The core information of antibacterial PP spunbond non-woven fabric is as follows: 1、 Core Technology and Performance The mainstream adopts a silver zinc composite inorganic slow-release antibacterial system, which is processed through melt blending or post finishing dipping and rolling processes, with an antibacterial rate of ≥ 99.9% against common pathogenic bacteria such as Escherichia coli and Staphylococcus aureus. It is resistant to high temperatures and compatible with spunbond processes, skin friendly and non irritating, in compliance with RoHS and REACH environmental regulations, and does not damage the basic physical properties such as breathability and stretchability of the fabric. 2、 Mainstream application scenarios 1. In the field of medical and health care: used for disposable protective clothing, surgical drapes, medical masks, and disinfectant bags, meeting medical grade hygiene compliance requirements; 2. In the field of maternal and child hygiene: as the surface layer of diapers, the bottom fabric of sanitary napkins, and the substrate of urine isolation pads, to prevent bacterial growth; Household daily use areas: pet pads, dust removal wiping cloths, non-woven fabric lining for home textiles, to suppress odors and mold growth; 3. Industrial filtration field: spunbond filtration substrates for fresh air and air conditioning to prevent bacterial growth after long-term use of the filter materials. 3、 Selection criteria and procurement considerations for PP spunbond nonwoven fabric 1. Core selection criteria 1. Basic parameters: Prioritize confirming that the weight and width match the production equipment. Choose 20-50g/㎡ for conventional sanitary material scenarios and 40-60g/㎡ for medical protection scenarios, balancing strength and breathability. 2. Antibacterial grade: Basic models with antibacterial rate ≥ 90% must be selected for ordinary civilian scenarios, while medical/maternal and child scenarios must meet AATCC 100 and GB/T 20944.1 standards with antibacterial rate ≥ 99%. 2. Virtual label identification method 1. Do not rely solely on verbal promises from the manufacturer. It is necessary to request an antibacterial performance testing report issued by a third-party authoritative organization to verify whether the testing standards match your usage scenario. 2. After receiving the sample cloth, you can conduct a simple test on your own: cover the contaminated sample on the surface of the cloth and culture for 24 hours, compare it with ordinary non-woven fabric to observe the growth of bacterial colonies, and preliminarily verify the antibacterial effect. 3. Procurement landing process 1. First, clarify the usage scenario and performance requirements with the manufacturer, apply for free sample fabric, complete the full performance verification, and then place a small batch trial order to confirm that the fabric is fully compatible with our own production process. Then, proceed with large-scale orders to reduce trial and error costs. In July 2026, the mainstream ton price of this category was in the range of 12000-15000 yuan. Products that are much lower than this price are likely to have insufficient addition of antibacterial masterbatch and performance that does not meet the standards. It is important to pay close attention to this when purchasing.

Based on the background of supply and demand, as well as price trends in the PP non-woven fabric market in July 2026, there is currently no clear signal of a turning point in the industry. Combining with existing market dynamics, the following analysis can be made: 1. Current market fundamentals As of mid July 2026, the operating rate of the PP non-woven fabric industry was 38.15%, a slight decrease of 0.13% compared to last week. The upward movement of upstream polypropylene fiber material costs led to a slight increase in product prices. However, industry and agriculture are still in the traditional off-season, and core downstream demand such as geotextiles, waterproof fabrics, and nursery fabrics continues to be weak, resulting in an overall supply-demand stalemate in the market. 2. Prediction of potential turning point time window 1. Short term dimension: From late July to early August, if geopolitical conflicts push up crude oil prices again, leading to a significant increase in upstream PP raw material costs, or if downstream agricultural and industrial sectors experience concentrated inventory replenishment after the off-season ends, the market may experience a temporary slight upward turning point; 2. Mid term dimension: Around September 2026, with the traditional peak season for downstream demand of gold, silver, and silver starting, coupled with the adjustment of the supply and demand pattern after the concentrated deployment of new production capacity in the second half of the year, the market is likely to usher in a clear trend turning point. 3. The key factors that trigger a turning point in the core 1. Upstream end: significant fluctuations in international crude oil prices, progress of new PP production capacity deployment, and centralized maintenance of oil to coal PP plants; 2. Demand side: The release rhythm of centralized orders in downstream geotextile, sanitary materials, and packaging fields, as well as the incremental situation of export orders.

  If you're sourcing nonwoven fabric, you've probably encountered a confusing array of options: Spunbond Meltblown SMS (spunbond + meltblown + spunbond) Spunlace Needle punch Thermal bond Chemical bond Each has its strengths and weaknesses. Each is suited to different applications. And each comes with a different price tag. In this article, we focus on the most common question buyers ask: "How does PP spunbond compare to the other nonwoven technologies — and which one should I choose?"   1. Spunbond vs. Meltblown These are the two most common nonwoven technologies — and they are often confused with each other. PropertySpunbondMeltblown Fiber diameter 15–35 microns 1–10 microns (much finer) Filtration efficiency Low to moderate Excellent Tensile strength High Low (brittle, easy to tear) Cost Lower Higher Typical applications Bags, gowns, covers, furniture Mask filter layers, oil absorbents, filtration media ✓ Spunbond wins on strength, cost, and versatility.✓ Meltblown wins on filtration, but is weaker and more expensive. Bottom line: If you need strong, durable, cost-effective fabric — choose spunbond. If you need filtration (e.g., mask middle layer) — choose meltblown.   2. Spunbond vs. SMS (Spunbond + Meltblown + Spunbond) SMS combines the strength of spunbond with the filtration of meltblown. It's often used in medical and hygiene products where both barrier and strength are needed. Property Single-Layer Spunbond SMS Fluid barrier Moderate High Bacterial filtration Low-moderate High Breathability Excellent Good Cost Low Higher (3 layers, more material) Typical applications Bags, dust covers, furniture, basic medical Surgical gowns, drapes, high-barrier masks ✓ Spunbond wins on cost, breathability, and simplicity.✓ SMS wins on barrier performance, but at a higher cost. Bottom line: If your application needs high fluid resistance (e.g., surgical gowns), choose SMS. If you need a good balance of performance and cost for lower-risk applications, single-layer spunbond is the smarter choice.   3. Spunbond vs. Spunlace (Hydroentangled) Spunlace uses high-pressure water jets to entangle fibers rather than thermal bonding. This creates a fabric that is soft, drapable, and cloth-like. Property Spunbond Spunlace Softness Good Excellent (cloth-like) Strength High Moderate Material options Mostly PP PP, polyester, rayon, cotton blends Cost Low Higher Typical applications Industrial, packaging, furniture, medical Wipes, beauty masks, face wipes, premium hygiene ✓ Spunbond wins on strength, cost, and durability.✓ Spunlace wins on softness and cloth-like feel. Bottom line: If you're making industrial bags, furniture covers, or medical gowns, spunbond is the better choice. If you're making premium facial wipes or skincare products that need a soft, cloth-like feel, spunlace is better — but expect to pay more.   4. Spunbond vs. Needle Punch Needle punch nonwoven is made by mechanically barbed needles that push fibers through the web, entangling them. This produces a heavy, thick, highly durable fabric. PropertySpunbondNeedle Punch Thickness Thin Thick Strength High (thin) Very high (thick) Weight (GSM) 10–150gsm 100–1000+ gsm (much heavier) Breathability Excellent Moderate Cost Low Higher (more material, slower production) Typical applications Packaging, medical, furniture, agriculture Carpet backing, geotextiles, insulation, automotive felt ✓ Spunbond wins on breathability, cost, and versatility in lighter applications.✓ Needle punch wins on thickness, weight, and heavy-duty durability. Bottom line: If you need thin, lightweight, breathable fabric — spunbond. If you need thick, heavy, felt-like fabric — needle punch.   5. Spunbond vs. Thermal Bond (Carded + Calender) Thermal bond (sometimes confused with spunbond) uses staple fibers (short cut fibers) that are carded into a web and then thermally bonded — no continuous filaments. PropertySpunbondThermal Bond (Carded) Fiber type Continuous filament Staple fiber (short cut) Linting/fraying None Can have surface lint Strength High Moderate Softness options Good Can be very soft Typical applications Medical, packaging, furniture, agriculture Wipes, filters, insulation, lightweight covers ✓ Spunbond wins on strength, lint-free performance, and production speed.⚠ Thermal bond can be softer but sacrifices strength and may lint.   Decision Guide: Which Nonwoven Should You Choose? Use this quick reference to match your application to the right nonwoven technology: If You Need...Choose...Why Low cost, high strength, durability Spunbond Continuous filaments = strong and affordable High filtration efficiency Meltblown Microfibers capture fine particles Fluid barrier + strength (surgical use) SMS Spunbond + meltblown combo Soft, cloth-like feel Spunlace Water-entangled for drape and softness Heavy, thick, felt-like material Needle punch Barbed needles create thick, dense fabric Lint-free, medical-grade cleanliness Spunbond No loose fibers, no fraying   Why Spunbond Is the Most Versatile Choice Among all nonwoven technologies, spunbond stands out for several reasons: Cost-effective — high-speed production, low raw material cost Strong — continuous filament structure provides superior tear strength Lint-free — no loose fibers, suitable for cleanroom and medical use Breathable — open structure allows air and moisture vapor to pass Printable — smooth surface accepts high-quality graphics Recyclable — single-polymer PP is compatible with recycling streams Versatile — works for packaging, medical, furniture, agriculture, and more At Heng Hua Nonwoven, we specialize in single-layer PP spunbond. Why? Because for the majority of applications, spunbond offers the best balance of performance, cost, and sustainability.

  No manufacturing process is perfect. Even with modern extrusion lines and strict quality controls, polypropylene spunbond nonwoven fabric can occasionally have defects. The difference between a good supplier and a great one is not whether problems occur — but how quickly they are identified, understood, and fixed. In this article, we'll walk through the most common quality issues in PP spunbond nonwoven, what causes them, and — most importantly — how to solve them. Whether you're a buyer, a converter, or a fellow manufacturer, this guide will help you spot problems early and work with your supplier to resolve them. 1. Pinholes & Visible Holes The Problem: Small, visible holes or thin spots in the fabric that allow light to pass through. These compromise barrier properties, tear strength, and appearance. Common causes: Contamination in the polymer melt (dust, degraded resin, or char) Clogged or partially blocked spinneret holes Inconsistent polymer flow due to pump or temperature fluctuations Foreign particles on the forming belt Solutions: Prevention: Install high-quality filtration systems and perform regular spinneret cleaning Inspection: Use online optical inspection (light table or laser scanners) to detect pinholes during production Fix: Adjust polymer melt temperature and pump speed to ensure consistent flow Quality check: Always hold a sample roll up to light or use a light table before shipment 2. Thickness Variation (GSM Fluctuation) The Problem: The fabric weight (GSM) is not consistent across the roll or along the length. Some areas are heavier, some lighter. This leads to uneven strength, poor print, and customer complaints. Common causes: Fluctuations in the extruder screw speed or polymer pump output Uneven cooling (quench air) — filaments cool at different rates Vacuum pressure variations on the forming belt Calender roller temperature or pressure inconsistency Solutions: Stabilize melt flow: Use a high-quality metering pump and maintain consistent extruder temperature Balance quench air: Ensure airflow is uniform across the full width of the web Maintain vacuum: Clean forming belts regularly and check for blockages Calender control: Monitor roll temperature and pressure across the width 3. Low Tensile Strength (Fabric Tearing Too Easily) The Problem: The fabric does not meet the specified tensile strength — it tears too easily in machine direction (MD) or cross direction (CD). This compromises durability for bags, covers, and gowns. ⚠️ This is one of the most common — and most frustrating — issues in the industry. Root causes of low tensile strength: A. Incorrect Basis Weight (GSM Too Low)The fabric is simply too light for the application. A 50gsm fabric will never have the tensile strength of a 100gsm fabric. If the supplier is offering "high strength" at a very low GSM, the numbers may not add up. Strength requires polymer mass — there's no shortcut. B. Insufficient PP Content — Excessive FillersSome manufacturers reduce cost by adding fillers (e.g., calcium carbonate, talc) to the polymer. This lowers the actual PP content per square meter. Fillers do not bond or provide strength — they weaken the fabric. A roll with 30% filler will have roughly 30% lower strength than a 100% virgin PP roll of the same GSM. C. Low-Quality PP Resin from Substandard SuppliersNot all PP resin is the same. Off-spec resin, recycled resin of unknown origin, or resin with inconsistent MFI (melt flow index) can cause weak filaments. Some small, unregulated suppliers offer resin at very low prices — but the resulting fabric fails tensile tests consistently. Quality resin costs more for a reason. D. Poor Process ParametersEven with good resin, a manufacturer that doesn't adjust its production parameters carefully will produce weak fabric. This includes: Insufficient filament drawing (stretching) Under-bonding or over-bonding at the calender Incorrect quench air temperature and speed Extruder temperature profiles that degrade the polymer A manufacturer must actively monitor and adjust these parameters during the run — not just set them once and walk away. Red flag: If a supplier offers spunbond fabric at a price that seems too good to be true — it probably is. The savings likely come from fillers, low-grade resin, or corners cut in production. The cost of field failures and customer complaints will far outweigh the upfront savings. 4. Uneven Fabric Surface (Waviness / Buckling) The Problem: When laid flat on a table or on a converting machine, the fabric does not lie smoothly. It shows waves, ripples, or buckling — especially near the edges. This is often called "wavy edges," "baggy fabric," or "camber." Why this matters: An uneven surface prevents smooth printing, causes misalignment in bag-making, and creates wrinkles in laminated products. In automated lines, it can cause jams and rejects. Common causes: Uneven winding tension — if tension is too high in the middle and low at the edges, the fabric will buckle Calender roll temperature variation — hot spots or cold spots create differential shrinkage Inconsistent filament lay-down — if the forming belt has uneven vacuum or the web is laid unevenly, the fabric will have built-in stress Excessive stretching during rewinding — especially for lightweight fabrics Moisture absorption or release — PP doesn't absorb water, but temperature changes during shipping can create temporary surface distortion Solutions: Winding tension control: Use automatic taper tension systems that reduce tension as roll diameter increases Calender maintenance: Ensure roll surfaces are clean, smooth, and uniformly heated Web formation: Clean forming belts and check vacuum uniformity across the width Slitting and rewinding: Use sharp, aligned blades and moderate tension Storage: Keep rolls on flat surfaces; avoid stacking heavy rolls on top of each other 5. Edge Curling (Dog-Ear / Roll Edge Lift) The Problem: The edges of the fabric curl upward or inward, making it difficult to unwind, feed through machines, or print on. This is especially problematic for bag making and converting lines. Common causes: Uneven tension across the web during winding Edge trimming that creates uneven edge stress Calender pressure being higher at the edges than the center Over-tight winding on the core Solutions: Calender adjustment: Ensure even nip pressure across the full width Winding tension: Use tapered tension control — reduce tension as the roll diameter increases Edge trimming: Trim edges cleanly and consistently to avoid stress points Slitting: Use sharp, properly aligned slitting blades to avoid edge distortion 6. Static Charge Build-Up The Problem: The fabric generates static electricity during unwinding or converting. This attracts dust, causes layers to stick together, and can interfere with automated equipment or electronic components. Common causes: Polypropylene's natural insulating properties Low humidity in the production or converting environment High-speed unwinding or slitting creates friction and static Solutions: Antistatic additives: Add internal antistatic agents (e.g., glyceryl monostearate) during extrusion Surface treatment: Apply topical antistatic finishes Environmental control: Maintain 45–55% relative humidity in the production and converting areas Grounding equipment: Use anti-static bars or ionizing air guns on unwinding and slitting machines 7. Uneven Width / Telescoping Rolls The Problem: The roll is not uniform — layers slide sideways (telescoping) or the width varies along the roll length. This makes it impossible to run on automated lines. Common causes: Incorrect winding tension Misaligned edge guides or slitting position Inconsistent fabric width from the production line Vibration in the winder Solutions: Precise edge guiding: Use automatic edge guide systems (with infrared or ultrasonic sensors) Controlled winding tension: Use taper tension to reduce tension as roll diameter grows Regular calibration: Ensure slitting and winding equipment are properly aligned Monitor width: Use online width measurement to catch deviations 8. Surface Defects — White Spots, Streaks, or Dark Specks The Problem: Visible blemishes on the fabric surface — white spots (unmelted resin), dark specks (carbonized polymer or contaminants), or streaks (uneven melt flow). These ruin print quality and appearance. Common causes: Unmelted resin pellets (white spots) from inadequate extrusion temperature Carbon buildup on the spinneret or die (dark specks) Contamination in the raw material Uneven melt flow due to temperature fluctuations Solutions: Precise temperature control: Maintain consistent extrusion and die temperatures Regular cleaning: Schedule spinneret and die cleaning to prevent carbon buildup Quality raw material: Source high-quality virgin resin from reputable suppliers Filtration: Use fine-mesh filters (e.g., 40–60 mesh) to remove contaminants Quick Troubleshooting Reference Quality IssueLikely Root CauseQuick Check Pinholes Clogged spinneret or contamination Hold fabric to light; check for repeats GSM variation Pump fluctuation or quench air imbalance Weigh samples from edge, center, edge Low tensile strength Low GSM, fillers, poor resin, or bad process parameters Test MD and CD; check ash content for fillers Uneven surface Winding tension or calender temperature variation Lay flat on table; check for waves Edge curling Uneven calender pressure or winding tension Lay flat; measure curl height Telescoping roll Winding tension or edge guide problem Check roll ends; measure width   The Bottom Line Quality issues in spunbond nonwoven are preventable, detectable, and solvable. The key is having a supplier that understands the root causes and has the systems in place to prevent them. Most quality problems trace back to three things: Cheap materials — fillers, low-grade resin, recycled content Poor process control — manufacturers who don't monitor or adjust parameters Choosing a supplier who invests in quality resin, careful production will save you headaches — and money — in the long run.

UV resistant PP spunbonded non-woven fabric is a special non-woven material that adds weather resistant masterbatch, light stabilizer and other additives in the production process of conventional PP spunbonded non-woven fabric to achieve UV resistance and anti-aging function. The core information is as follows: 1、 Core performance parameters It is made of 100% brand new polypropylene as raw material, with a conventional weight coverage of 9-150gsm, and a width that can be customized according to needs. In addition to its basic breathable, water repellent, and non-toxic characteristics, it can effectively resist outdoor UV erosion, greatly extending its service life in outdoor scenes. Some products have passed international certifications such as REACH and OEKO TEX. 2、 Mainstream application scenarios In the agricultural field, as a grass proof cloth, fruit tree cold proof cloth, and seedling cover cloth, it is suitable for outdoor strong ultraviolet areas, reduces pesticide use, preserves moisture and promotes growth; Outdoor engineering: used for car covers, geotechnical green coverings, and outdoor furniture fabrics, which are not easily brittle or broken after long-term outdoor use; Other scenarios: Outdoor sunscreen products, industrial protective products, suitable for long-term exposure to sunlight. 3、 Market situation in July 2026 The agricultural grade UV resistant products of Fuzhou Henghua New Materials Co., Ltd. are as low as USD1.66/KG, with a ton price 10% -20% higher than conventional ordinary PP non-woven fabrics. The price difference between products of different weight and weather resistance levels is significant, and color and width customization are supported. Conventional products are available in stock, while special customized products can be shipped in about 7 days.

1、 Raw material safety: the natural advantage of polypropylene The main raw material for PP nonwoven fabric is polypropylene (PP), which itself has high chemical stability. Just like mineral water bottles, they do not release harmful substances at daily temperatures. During the production process, plasticizers and other potentially toxic additives are not added, ensuring the safety of materials from the source. 2、 Process control: Transformation under high temperature During the manufacturing process, polypropylene fibers are formed through high-temperature melt blown or spunbond processes. This physical change is similar to melting ice into water and then freezing it, without producing new chemicals. Legitimate manufacturers will strictly control the production environment to avoid pollution risks during the processing. 3、 Application testing: Multi scenario verification From medical masks to food packaging, PP nonwoven fabric has undergone strict practical application testing. Under normal usage conditions, including contact with skin or short-term exposure to food, there will be no toxicity issues. However, it should be noted that long-term high temperature (over 120 ℃) environments may affect material properties.

As of early July 2026, the PP spunbond nonwoven fabric industry is showing a market trend of "cost decline but weak demand", while the production capacity is clearly upgrading towards green and functional upgrades. 1、 Recent market trends 1‌. Price and market trend: In late June 2026, due to the significant decline in the cost of raw material polypropylene (PP), the theoretical profit of PP non-woven fabric slightly rebounded. However, insufficient terminal orders led to limited follow-up of spot prices, and the market fell into a stalemate. The reference price for mainstream spunbond non-woven fabrics in Shandong region is about 12000 yuan/ton, and the actual price needs to be negotiated. 2‌. Supply and demand pattern: The industry is facing a two-way squeeze of "cost collapse and weak demand", with a lack of upward driving force, and there is a risk of passive downward shift in the short-term price center. Although global sales have reached 123.784 billion yuan by 2025 and are expected to grow to 184.8 billion yuan by 2032, there is currently significant pressure to reduce inventory. 2、 Technology and Application Trends 1. Performance optimization: Leading enterprises focus on lightweight and high-strength, uniform weight (10-100g/㎡), and customized functions (antibacterial, anti-static, flame retardant) to adapt to segmented scenarios such as medical, industrial filtration, and agricultural cold protection. 2. Green manufacturing: The production process emphasizes low-carbon and energy-saving, and the products comply with domestic and international environmental standards, helping to promote green upgrades in packaging, daily use, and other fields. The share of domestic materials in the international supply chain is steadily increasing. ‌

In July 2026, the overall price of PP spunbond nonwoven fabric in the domestic market was in a low fluctuation range. Due to factors such as raw material costs, specifications, usage, and procurement volume, the price difference between different categories was significant. The specific market situation is as follows: 1、 Bulk tonnage market 1. The mainstream quotation for SS/SS spunbond non-woven fabric in the Shandong market is 10300-11000 yuan/ton. The industry as a whole is driven by the decline in upstream polypropylene raw material prices, and theoretical profits have slightly recovered. However, weak terminal demand has led to actual transactions mainly being negotiated, and some low-end source prices can be lowered to 9500-10000 yuan/ton. 2、 Retail by specification/small batch price 1. Lightweight products for engineering protection and agricultural seedling cultivation: Low weight base models can be as low as 0.21-0.5 yuan/square meter, suitable for slope protection, grass prevention, and crop coverage scenarios; 2. Conventional home textiles, packaging, and mask fabrics: The unit price is mostly in the range of 0.9-8.8 yuan/meter, and the raw material products priced by kilogram are about 9.8-14 yuan/kilogram, supporting width and color customization; 3. High value-added functional products: such as antibacterial and sanitary grade, UV resistant and weather resistant, and food grade certified products, with a unit price of 10-15 yuan/piece/roll. The price of special customized products will further increase. The current market is in a stalemate stage of "cost decline but insufficient demand", with a lack of clear upward momentum in short-term prices, and there is still a possibility of a slight downward shift in focus.

  You've chosen the right fabric. The right GSM. The right width. The right color. But there's one more detail that matters — and it's often overlooked: What core tube size should your rolls have? It seems like a small detail. But choosing the wrong core size can affect shipping costs, production efficiency, and even fabric quality. Here's everything you need to know about selecting the right roll core tube for your PP spunbond nonwoven fabric. What Is a Roll Core Tube? A roll core tube (also called a paper core or cardboard core) is the cylindrical center around which nonwoven fabric is wound. It provides structural support to the roll and allows the fabric to be mounted on dispensing or converting equipment. Core tubes are typically made of high-density kraft paper — strong enough to support the roll weight during winding, handling, and shipping. The Three Standard Core Sizes In the nonwoven industry, there are three standard inner diameters you need to know: Core SizeInner Diameter (ID)How It Is Produced 3-inch core 76.2 mm Standard initial core — directly from the production line 2-inch core 50.8 mm Requires rewinding (converted from 3-inch) 1.5-inch core 38.1 mm Requires rewinding (converted from 3-inch) 3-Inch Core — The Industry Standard The 3-inch core is the most common size in the nonwoven industry. At Heng Hua Nonwoven, like most manufacturers, our production line produces fabric directly onto 3-inch cores. This is the "initial" or "primary" core — no extra steps, no additional handling, just straight from the line. Why 3-inch is the standard: Directly compatible with most nonwoven production lines Fits most converting equipment (bag making, mask machines, slitting lines) Strong enough for typical roll weights Cost-effective — no additional rewinding step required Lowest risk of quality issues 2-Inch and 1.5-Inch Cores — Rewinding Required Some customers request smaller cores — 2-inch or 1.5-inch — to reduce roll size. But unlike 3-inch, these are not produced directly on the main production line. They require a rewinding process (also called "slitting and rewinding" or simply "rewind"). In rewinding, a large 3-inch core roll is unwound, then rewound onto a smaller core. This adds an extra production step, which means: Higher cost — additional labor and machine time Longer lead time — rewinding takes time Potential quality risk — fabric is handled twice Why Choose a Smaller Core? The Container Advantage The main reason customers ask for 2-inch or 1.5-inch cores is shipping efficiency. A smaller core diameter means the overall roll diameter is smaller for the same roll length. Even a 1–2 cm reduction in roll diameter can make a significant difference — it might mean fitting one extra row of rolls when laid horizontally inside a shipping container. Over a full container load, that one extra row translates to real freight savings. For high-volume buyers, this is a compelling reason to consider smaller cores. Critical Rule 1: GSM Limits for Rewinding Important: For fabrics of 40gsm or lighter, we do not recommend rewinding. For 30gsm and below, rewinding is strongly discouraged. Why? Because lightweight nonwoven fabric is thin and delicate. The rewinding process subjects the fabric to tension, stretching, and mechanical handling. For light fabrics, this can cause: Thinning — the fabric stretches and becomes even lighter, changing the GSM Deformation — width shrinkage or uneven edges Surface damage — pilling, abrasion, or fiber disturbance Loss of uniformity — inconsistent GSM across the roll Rule of thumb: 30gsm and below: MUST use 3-inch core. Rewinding will damage the fabric. 40gsm: Rewinding is risky — evaluate carefully. 50gsm and above: Rewinding is generally safe with proper tension control. Critical Rule 2: Width Limits for Rewinding Rewinding is not just about GSM — fabric width matters just as much. Our rewinding machines have specific width capabilities. If a roll is too narrow, it cannot be rewound properly because the fabric will drift, shift, or wind unevenly. Our rewinding machine specifications: Rewinder 1: 1.6 meters (160 cm) width capacity Rewinder 2: 2.4 meters (240 cm) width capacity Width limits for rewinding: Fabric WidthRewinding Possible?Notes ≥ 140 cm (1.4m) Yes Stable rewinding, good edge alignment 130 cm (1.3m) and below No Fabric shifts, winds unevenly, edges become crooked 52 cm (0.52m) — too narrow No Cannot be rewound on our equipment Remember: 1.5 meters and 1.4 meters can be rewound. 1.3 meters and below cannot — the fabric will drift and wind crooked. Real-World Specification Examples Here are two examples to help you understand when rewinding works and when it doesn't: ✅ Example 1 — Rewinding OK Specification: 70gsm × 200cm width × 50m lengthRequested core: 2-inchVerdict: ✅ OK Why: 70gsm is heavy enough to handle rewinding tension. 200cm width is well within the 2.4m rewinder capacity. The fabric is stable, and 50m length is manageable. ✅ Example 2 — Rewinding OK Specification: 50gsm × 150cm width × 100m lengthRequested core: 1.5-inchVerdict: ✅ OK Why: 50gsm is above the 40gsm threshold. 150cm width is above the 130cm minimum. The 1.5-inch core is feasible with careful tension control. ❌ Example 3 — Rewinding NOT OK Specification: 25gsm × 52cm width × 200m lengthRequested core: 2-inchVerdict: ❌ NOT OK Why: 25gsm is below 40gsm — rewinding will stretch and thin the fabric. 52cm width is far below the 130cm minimum — the fabric will drift and wind crooked. This specification must stay on a 3-inch core. Decision Guide: Can Your Specification Be Rewound? Use this quick checklist to determine if your specification is suitable for rewinding to a smaller core: RequirementMust BeWhy GSM (fabric weight) ≥ 50gsm (ideally)> 40gsm (minimum) Below 40gsm, fabric stretches and thins during rewinding Fabric width ≥ 140cm Below 130cm, fabric drifts and winds unevenly Roll length Depends on GSM and width Longer rolls require more careful tension control Core Wall Thickness Matters Too Regardless of the inner diameter, the wall thickness of the core determines its compression strength. A thin core will crush under heavy roll weight or when clamped by a hydraulic chuck. Core SizeStandard WallHeavy-Duty Wall 3-inch core 5–6 mm 8–10 mm 2-inch core 5–6 mm 8–10 mm 1.5-inch core 4–5 mm 6–8 mm For any core size, if your roll weight exceeds 100–120 kg, we recommend upgrading to a heavy-duty wall. Summary: Core Size Decision Flow Quick decision guide: Is your fabric 40gsm or lighter? → Must use 3-inch core. No rewinding. Is your fabric width 130cm or narrower? → Must use 3-inch core. Cannot rewind. Is your fabric 50gsm+ and 140cm+ wide? → You can choose 2-inch or 1.5-inch via rewinding. Do you need maximum container efficiency? → Choose the smallest core that meets the above criteria. The Bottom Line Choosing the right core tube size is a balancing act between shipping efficiency and fabric quality — with physical machine limits in between. The rules are simple: 3-inch is the standard initial core — always works, lowest cost, lowest risk 2-inch and 1.5-inch require rewinding — extra cost and lead time, but improve container utilization 40gsm and below — do NOT rewind. Stay with 3-inch. 130cm width and below — do NOT rewind. Stay with 3-inch. 50gsm+ and 140cm+ — rewinding is feasible; choose 2-inch or 1.5-inch for container savings If you're unsure whether your specification can be rewound, just ask us. We'll check your GSM, width, and length against our rewinding capabilities and give you a clear recommendation. Looking for a reliable supplier of PP spunbond nonwoven rolls?

Detailed introduction of PP spunbond non-woven fabric: 1. Technical principles The production process of PP spunbond non-woven fabric mainly includes four steps: melting, spinning, mesh laying, and reinforcement. Firstly, the polypropylene particles are heated to a molten state and then extruded through the nozzle to form fine filaments. These filaments are stretched during the cooling process to form filaments with a certain strength. Then, these long filaments are randomly laid on the web forming machine to form a uniform fiber web. Finally, through methods such as hot rolling, chemical bonding, or mechanical reinforcement, the fibers in the fiber web are bonded to each other to form a stable non-woven fabric structure. 2. Characteristics *Non toxic and environmentally friendly: PP spunbond non-woven fabric uses polypropylene as raw material, which is non-toxic, odorless, and meets environmental requirements. It can be widely used in food packaging, medical supplies, and other fields. *High strength: Due to the characteristics of spunbond technology, PP spunbond non-woven fabric has high tensile strength and tear strength, and can withstand large external forces without being easily damaged. *Good breathability: The gaps between fibers make PP spunbond non-woven fabric have good breathability, suitable for occasions that require breathability, such as hygiene products, agricultural coverings, etc. *Soft and comfortable: PP spunbond non-woven fabric has a soft touch, comfortable to wear, and does not irritate the skin, so it is commonly used in the production of clothing, shoe materials, etc. Chemical corrosion resistance: Polypropylene material has good resistance to most chemicals, allowing PP spunbond nonwoven fabrics to be used in harsh environments. 3.

The main raw materials for spunbond nonwoven fabrics include polypropylene (PP), polyester (PET), polylactic acid (PLA), etc. The selection of these raw materials directly affects the performance and application areas of non-woven fabrics. The following are several common spunbond non-woven fabric materials and their characteristics: 1‌. Polypropylene (PP): Characteristics: Polypropylene is one of the most commonly used raw materials for spunbond nonwoven fabrics, with characteristics such as lightweight, chemical corrosion resistance, and UV resistance. Application scenarios: Widely used in fields such as healthcare, hygiene, packaging, etc. 2‌. Polyester (PET): Features: Polyester non-woven fabric has high strength, high temperature resistance, and good filtration performance. Application scenarios: mainly used for filtering materials, geotextiles, etc. 3. Polylactic acid (PLA): Characteristics: PLA is a biodegradable material with excellent environmental performance. Application scenarios: Suitable for environmentally friendly packaging, medical supplies, etc. In addition, the selection of raw materials for spunbond nonwoven fabrics also needs to consider processing techniques (such as spunbond and needle punching methods) and the performance requirements of the final product (such as breathability, wear resistance, etc.). The combination of different raw materials can meet diverse market demands.

      From a Nonwoven Roll Manufacturer to You Polypropylene (PP) fabric is everywhere. From medical gowns and shopping bags to furniture linings and agricultural covers — it's one of the most versatile materials in modern manufacturing. But like any material, PP fabric has strengths and weaknesses. Understanding both is key to choosing the right fabric for your application. Let's take an honest, balanced look at the pros and cons of polypropylene fabric.   What Is Polypropylene Fabric? Polypropylene fabric is a synthetic textile made from polypropylene resin, a thermoplastic polymer derived from petroleum. It can be produced as: Woven PP — flat tapes woven on a loom (heavy-duty bags, FIBC, tarpaulins) Spunbond nonwoven PP — continuous filaments bonded with heat (medical, hygiene, packaging, furniture) Meltblown PP — microfibers for filtration (mask filter layers) In this article, we focus primarily on spunbond nonwoven PP, the most versatile and widely used form.   The Pros of Polypropylene Fabric 1. LightweightPP fabric is extremely light. At comparable strength, it weighs 30–40% less than woven alternatives. This translates to lower shipping costs, easier handling, and less material waste. 2. Durable & Tear-ResistantSpunbond PP has uniform tear strength in all directions — unlike woven fabrics which tear easily along the weave. The continuous filament structure resists puncture and abrasion. 3. Chemical ResistancePP is highly resistant to most acids, alkalis, and solvents. It won't degrade from contact with common chemicals, making it ideal for industrial, agricultural, and medical applications. 4. Breathable Yet ProtectiveSpunbond fabric allows air and moisture vapor to pass through while blocking liquid and fine dust. This unique combination makes it perfect for medical gowns, diaper components, and agricultural covers. 5. Cost-EffectivePP fabric is significantly cheaper than alternatives like cotton, polyester, or laminates. High-speed production (up to 600 m/min) keeps costs low. 6. Excellent Print QualitySpunbond nonwoven has a smooth, paper-like surface that accepts high-quality flexo and gravure printing. Sharp logos, bright colors, and scannable barcodes are easy to achieve. 7. Lint-FreeUnlike cotton or woven fabrics, spunbond PP has no fraying or loose fibers. It cuts cleanly and stays clean — essential for medical, cleanroom, and food packaging applications. 8. RecyclablePP is 100% recyclable and has a well-established recycling stream. It can be reprocessed into new products, reducing environmental impact. 9. Hydrophobic (Water-Repellent)PP naturally repels water. It doesn't absorb moisture, so it stays dry, resists mold, and maintains strength even in humid conditions.   The Cons of Polypropylene Fabric 1. UV SensitivityThis is the biggest drawback. Without UV stabilizers, PP fabric degrades rapidly in sunlight — typically within 2–6 months. The polymer chains break down, causing brittleness, cracking, and loss of strength. Solution: UV stabilizers can extend outdoor life to 1–3 years. 2. Low Heat ResistancePP begins to soften around 150°C (302°F) and melts at approximately 160–170°C. It's not suitable for high-heat applications or environments where it contacts hot surfaces. Solution: Use alternative materials (e.g., polyester) for high-heat applications.(we focus on polypropylene) 3. Poor Adhesion Without TreatmentBecause PP is non-polar, adhesives and coatings don't stick easily to untreated surfaces. This can be a challenge for certain bonding or lamination processes. Solution: Corona treatment or plasma treatment improves surface energy for better adhesion. 4. Static Charge Build-UpPP is an insulator and can generate static electricity, especially in dry conditions. This can attract dust, cause discomfort (in clothing), or interfere with electronic components. Solution: Antistatic additives or surface treatments are available. 5. Not BiodegradableWhile PP is recyclable, it is not biodegradable. In landfill conditions, it persists for hundreds of years. This is a sustainability concern for single-use products. Solution: PP is widely recycled; closed-loop programs are growing. 6. Can Be Damaged by Oil and GreaseWhile PP resists most chemicals, it swells and softens when exposed to hydrocarbon solvents — including oils and greases. This limits its use in certain automotive and industrial settings.   Pros and Cons at a Glance AspectAdvantageDisadvantage Weight Lightweight, reduces shipping cost — Strength Uniform tear resistance Degrades with UV exposure Chemical resistance Resists most acids & alkalis Damaged by oils & solvents Breathability Excellent — Heat resistance Good up to ~100°C Softens at 150°C, melts at 170°C Printability Excellent (spunbond) Poor (woven PP) Recyclability 100% recyclable Not biodegradable Cost Low cost vs. alternatives —   How to Overcome the Limitations Most of PP's disadvantages have practical solutions: LimitationSolution UV degradation UV stabilizers Low heat resistance Avoid high-heat applications; use PP only below 100°C continuous Poor adhesion Corona treatment, plasma treatment, or primer Static charge Antistatic additives (e.g., glyceryl monostearate) Oil sensitivity Avoid contact with oils; use coatings if needed   When Should You Choose Polypropylene Fabric? Choose PP fabric when: You need lightweight, low-cost material You require breathability with fluid resistance (medical, hygiene) You want sharp, colorful print quality (packaging, bags) The application is indoor or protected from UV (furniture, medical, storage) You need chemical resistance (agriculture, industrial) Avoid PP fabric when: Continuous outdoor UV exposure (unless UV-stabilized) Operating temperatures above 100°C Contact with hydrocarbons (oils, gasoline, certain solvents) Biodegradable materials are required by regulation   The Bottom Line Polypropylene fabric is not a miracle material — but it is a practical, versatile, and cost-effective solution for a huge range of applications. Its strengths (lightweight, strong, chemical-resistant, breathable, printable, lint-free) far outweigh its weaknesses (UV sensitivity, heat limitations, oil sensitivity) — especially when you choose the right grade and additive package.
