PP spunbond nonwoven fabric

The core differences of PP spunbond nonwoven fabric with different weight are concentrated in three dimensions: physical properties, applicable scenarios, and procurement costs. Based on your previous selection needs, the specific differences are as follows: 1、 Core performance differences 1. Low weight (9-30g/㎡): The fabric is lightweight, highly breathable, with low tensile strength, overall soft feel, light weight per unit area, and almost no stiffness. 2. Medium weight (30-80g/㎡): Balanced performance, balancing breathability and tensile strength, flat and uniform fabric surface, with basic stiffness, making it the most widely used mainstream range in the market. 3. High weight (80-150g/㎡): The fabric surface is thick, with high tensile and tear strength, strong load-bearing capacity, and good stiffness. Some high weight products have a harder hand feel and are more difficult to fold and store. 2、 Differences in applicable scenarios 1.9-30g/㎡: Communication cable core wrapping, disposable mask surface, agricultural ultra-thin seedling covering cloth, only suitable for extremely lightweight wrapping and protective scenarios. 2.30-80g/㎡: ordinary shopping bags, medical isolation gowns, diaper surface, home bed sheets, are the main selection range for daily civilian and conventional sanitary materials. 3.80-150g/㎡: Suitable for industrial scenarios that require high load-bearing and wear resistance, including load-bearing shopping bags, geotextiles, automotive interiors, and engineering protective materials. 3、 Cost and processing differences The higher the weight, the more raw materials are consumed per square meter, and the purchasing unit price increases synchronously. Although the ton price of 120g/㎡ products is close to that of low weight products, the cost per square meter is six times that of 20g/㎡ products. 2. Fabrics with excessive weight (>120g/㎡) will become harder, and the heat sealed edges are prone to brittleness and cracking, requiring higher adaptability for downstream bag making and laminating equipment.

There is no unified universal mandatory national standard for the tensile strength and elongation of PP spunbond nonwoven fabric. The core indicators vary significantly with weight and application scenarios, and there are clear testing execution standards. The specific benchmarks are as follows: 1、 Core Test Execution Standards The industry standard for testing is GB/T 24218.3 or GB/T 3923.1-2013, corresponding to international standards ISO 13934-1 and ASTM D5035. The testing requires taking samples from both the longitudinal (MD) and transverse (CD) directions for testing. 2、 Benchmark indicators for conventional products of different weights 1.15g/㎡ conventional spunbond fabric: longitudinal tensile strength of about 30N/5cm, elongation at break of 90% -100% 2.40g/㎡ ordinary spunbond PP fabric: longitudinal tensile strength of about 85N/5cm, transverse strength of about 72N/5cm, elongation at break of about 25% 3.50g/㎡ conventional spunbond fabric: longitudinal tensile strength can reach 124N/5cm 4.150g/㎡ industrial grade geotextile: The national standard requires a longitudinal fracture strength of ≥ 9.0kN/m 3、 Industry requirements for special scenarios 1. Ordinary conventional PP spunbond non-woven fabric: The elongation at break is generally in the range of 90% -100%, and the ductility is excellent 2. Medical protective scenarios: It is necessary to balance tension and high elongation to avoid clothing tearing during wearing and activities 3. Common problems with inferior products: Some manufacturers excessively add filler masterbatch to increase tensile strength, which can lead to extremely low elongation at break, brittle materials, and easy tearing and damage in actual use. When purchasing, both indicators need to be verified at the same time, not just the tensile strength. Contact us for samples or a quote

1、 Complete production process 1. Raw material pretreatment: Mix polypropylene particles with antibacterial masterbatch such as nano zirconium phosphate loaded with silver in precise proportions, and remove moisture through hot air drying to avoid the formation of bubbles during subsequent melting processes that may affect spinning quality. 2‌. Melt extrusion: The mixed raw materials are fed into a screw extruder and heated to melt and plasticize in the temperature range of 220-250 ℃. The melt is then transported to the spinning component through a metering pump at a constant quantity and pressure. 3. Spinning into a web: The melt is extruded through the micropores of the spinneret to form continuous filaments, which are drawn by high-speed airflow and evenly laid on a moving web curtain to form a fiber web. 4. Reinforcement molding: The fiber mesh is reinforced by hot bonding using a hot rolling mill. Some high-end products are equipped with a water jet/needle punching composite process to ensure that the antibacterial components are evenly attached to the inside of the fiber, avoiding rapid loss during subsequent use. 5. Post treatment and finished product: After cooling and shaping, performance verification, the product is cut and rolled according to the specified width to obtain the final product. The qualified product can still maintain a stable antibacterial rate after 5 water washes. 2、 Core application areas 1‌. In the field of medical protection, it is used to make disposable surgical gowns, sterilization bags, inner layers of medical masks, and surgical drapes. It can effectively inhibit the growth of pathogenic bacteria, reduce the risk of cross infection, and comply with the GB/T20944.3 medical antibacterial material standard. 2. In the field of hygiene for mother and baby: As the surface layer of diapers, the bottom fabric of sanitary napkins, and the base material of urine pads, it is skin friendly and non irritating, avoiding the proliferation of bacteria in intimate use scenarios and improving the hygiene of use. 3‌. Household daily use areas: pet pads, antibacterial and dust removal wiping cloths, home textile lining, can suppress odors and mold growth, suitable for damp and prone to bacterial growth in home scenes. 4‌. In the field of industrial filtration, spunbond filtration substrates for fresh air systems and air conditioners are used to prevent bacterial adhesion and mold growth after long-term use, thereby improving the hygiene level of air filtration.

As of August 21, 2026, public information shows that PP raw material prices are relatively strong, but downstream demand for PP non-woven fabrics is still weak, and the market is in a stage of "cost support, demand game". 1. PP raw material prices continue to rise According to data from Shengyi Society, the reference price for PP wire drawing on August 21st was 9216.67 yuan/ton, an increase of 2.71% from 8973.33 yuan/ton on August 1st. On August 19th, the mainstream price of PP wire drawing in Qingzhou market was about 9150-9250 yuan/ton. The current price support mainly comes from the strengthening of crude oil and propylene costs, as well as some equipment maintenance; However, the downstream delivery efforts are insufficient, and the continued significant increase in prices still requires demand coordination. 2. The industry's operating rate is at a relatively low level The operating rate of the PP non-woven fabric industry in July 2026 was about 38.14%, a decrease of 2.48 percentage points from the previous period. The demand shows obvious differentiation: 1. The demand for takeaway insulated bags and packaging non-woven fabrics is relatively acceptable; 2. The demand for sanitary materials such as diapers has decreased; 3. Industrial and agricultural products such as geotextile, waterproof cloth, covering cloth, and seedling raising cloth are in the off-season. 3. Market judgment: Short term cost push, future demand dependent The main contradictions in the current industry can be summarized as follows: PP raw material price increase → spunbond non-woven fabric cost increase → factory pressure to raise prices; But insufficient terminal orders → cautious downstream procurement → limited transmission of price increases. 4. Actual impact on production and export enterprises: 1. The competition for regular white and low weight products is still fierce, and simply following the price increase of raw materials can easily lead to losing orders. 2. Packaging bags, insulation bags, furniture packaging, medical protection, and high-strength composite materials are more worthy of attention. 3. It is recommended to use a valid quotation and include a clause for PP raw material price fluctuations in the bulk order. 4. In foreign trade development, emphasis should be placed on weight stability, tensile strength, uniformity, color consistency, and delivery time, rather than just quoting low prices.   Contact us for samples or a quote

Meta Description: Discover what spunbond polypropylene (PP) nonwoven fabric is, how it's made, its key properties, and why it's a critical material across industries from medical to agriculture.   If you've ever used a reusable shopping bag, worn a disposable medical gown, or noticed a protective cover over a newly seeded field, you've likely encountered spunbond polypropylene. This versatile engineered fabric is one of the most widely used nonwoven materials in the world. But what exactly is it, and what makes it so special? This guide breaks down the essentials of spunbond polypropylene (PP) fabric, explaining its manufacturing process, unique characteristics, and the reasons behind its global popularity. The Simple Definition Spunbond polypropylene is a type of nonwoven fabric made from 100% polypropylene polymer. The term "spunbond" refers to the specific manufacturing process where continuous filaments are spun, laid into a web, and then bonded together—without weaving or knitting. The result is a strong, uniform, and porous sheet material that balances performance with cost-effectiveness. How is Spunbond Polypropylene Made? (The 3-Step Process) Understanding the production process helps explain the fabric's consistent quality and properties. 1. Extrusion & Spinning Polypropylene resin—in the form of small pellets—is melted and extruded through a die called a spinneret, which contains hundreds of tiny holes. As the molten polymer is forced through these holes, it forms continuous, fine filaments (like endless strands of spider silk). 2. Web Formation These still-soft filaments are then stretched (a process called drawing) by high-speed air, which aligns their molecules, increasing their strength. They are then pneumatically laid onto a moving conveyor belt in a random, overlapping pattern, forming a uniform, unbonded web. 3. Bonding The final and critical step is bonding the web to give it integrity. For polypropylene, the primary method is thermobonding. The web passes through heated calendar rollers (often with an embossed point-bond pattern). The heat slightly melts the PP filaments at their交叉点, fusing them together as they cool. This creates a strong but breathable fabric. Key Properties & Advantages: Why It's So Widely Used The combination of the base material (polypropylene) and the spunbond process results in a unique set of properties: High Strength-to-Weight Ratio: Despite being lightweight, it offers excellent tensile and tear resistance, especially in the machine direction. Dimensional Stability: It does not fray or unravel like woven textiles, and it is resistant to stretching and shrinking. Inherently Inert & Hypoallergenic: Polypropylene is chemically resistant to most acids, alkalis, and solvents. It is also non-toxic and safe for skin contact, making it ideal for hygiene products. Moisture Resistance: PP is hydrophobic—it does not absorb water. This makes the fabric an excellent moisture barrier and allows it to dry quickly. Breathable & Porous: The point-bonded structure allows air and vapors to pass through, preventing condensation and increasing comfort in applications like protective covers. Cost-Effective Manufacturing: The process is fast, continuous, and highly automated, allowing for high-volume production at a low cost per square meter. Customizable: Its properties can be easily modified. It can be treated to be hydrophilic (water-absorbing), given UV stabilization for outdoor use, or have antimicrobial and anti-static properties added. Weight (GSM), color, and width can all be tailored.   Common Applications Across Industries This versatility translates into hundreds of everyday and industrial uses: Medical & Hygiene: The #1 use. Surgical gowns, drapes, face masks, shoe covers, diaper liner stock, and adult incontinence products. Geotextiles & Agriculture: Weed control fabric, crop covers, soil stabilization mats, and drainage layers due to its durability and permeability. Packaging: Reusable tote bags, protective furniture wraps, breathable produce packaging, and mailer envelopes. Furniture & Bedding: As a backing for carpets and upholstery, and as a protective dust cover in mattresses and furniture. Filtration: Used as a pre-filter layer in HVAC systems, water filters, and vacuum bags.   Spunbond vs. Other Nonwovens: A Quick Comparison Spunbond vs. Meltblown: Meltblown PP creates extremely fine fibers, resulting in superior filtration (used in N95 masks) but is less strong. Often, they are combined to form SMS (Spunbond-Meltblown-Spunbond) fabric, which is strong, breathable, and an excellent barrier—common in medical gowns. Spunbond vs. Needlepunched: Needlepunched fabrics are mechanically entangled, making them thicker and more felt-like, ideal for insulation or wipes, but generally less smooth and consistent than spunbond. Spunbond vs. Woven Polypropylene: Woven PP is made from tapes, is heavier, and can have a checkerboard look. It's very strong for bags but is less cost-effective for disposable/lightweight applications and is not a true barrier.   Partner with a Spunbond Polypropylene Expert As a manufacturer specializing in spunbond polypropylene, we control the process from resin to roll.

  Dear Valued Customers and Partners, did you know that proper storage is a critical factor in preserving the superior performance of our polypropylene (PP) spunbond nonwoven fabric?    Incorrect storage conditions can lead to product aging, reduced fabric strength, or even render the material unusable, ultimately disrupting your production process and final product quality. To help you maximize the potential of our high-quality non-woven products, we have prepared this detailed scientific storage guide.   Core Storage Principles:   1. Palletize and Keep Off the Ground   Use Pallets: Always place all rolls or sheets on sturdy, flat wooden or plastic pallets. This not only prevents packaging damage but also effectively isolates moisture from the floor.   No Direct Ground Contact: Never stack products directly on the ground, as even concrete floors can become damp under certain conditions, posing a latent threat to the non-woven fabric.   2. Provide an Ideal Indoor Environment   Control Temperature & Humidity: The warehouse or storage room should be kept cool and dry. We recommend an ambient temperature between 15°C - 30°C and a relative humidity of 50% - 65%.   Ensure Good Ventilation: Maintain adequate air circulation to prevent stuffiness and moisture buildup. Ensure that vents do not introduce external dust.   3. Protect from UV Light and Heat   Avoid Sunlight/UV Rays: Ultraviolet (UV) light is the primary cause of polypropylene degradation. It is essential to store nonwoven fabric in a location completely shielded from direct sunlight. Windows should be covered with blackout curtains or UV-blocking film.   Keep Away from Heat Sources: Store products away from any heat sources such as radiators, boilers, or heaters, as sustained high temperatures can cause material deformation or performance degradation.   4. Follow Stacking Guidelines   Limit Stacking Height: Adhere to the maximum number of stacking layers indicated on the packaging. Over-stacking can exert excessive pressure on the bottom rolls, causing permanent deformation and issues in subsequent processing.   Practice FIFO (First-In, First-Out): Establish and strictly follow a FIFO inventory management system. This ensures that the oldest stock is used first, preventing natural aging due to prolonged storage.   Conclusion: By following these simple storage principles, you can significantly extend the service life of your PP spunbonded nonwoven fabric, and ensure its consistent performance.   Proper storage is not only a protection for the product but also a safeguard for your production efficiency.
