polypropylene spunbond nonwoven fabric

                              The difference between spunbonded nonwoven and pp nonwoven Spunbonded nonwovens and PP nonwovens are two different nonwovens production processes and products. They have significant differences in production processes, performance characteristics, application fields, etc. The characteristics of these two nonwovens and the differences between them will be described in detail below. 1. Spunbonded nonwoven fabrics Spunbonded nonwoven fabric is a non-woven fabric produced using a spunbond process. Spunbond is a process in which polymers are made into fibers directly through melt spinning techniques, and then these fibers are bonded together through thermal bonding or chemical bonding methods to form a nonwoven fabric. Spunbonded nonwoven fabrics have the following characteristics: 1. Production process: Adopt melt spinning technology, continuous production, high efficiency. 2. Fiber structure: The fiber is thick and has a network structure with good strength and toughness. 3. Physical properties: High strength and tensile properties, wear resistance and tear resistance. 4. Purpose: Widely used in packaging, disposable supplies, building materials and other fields. 2. PP non-woven fabrics PP nonwoven fabric is a kind of nonwoven fabric made from polypropylene (PP) as raw material and using nonwoven process. PP non-woven fabrics have the following characteristics: 1. Raw materials: Mainly use polypropylene, an environmentally friendly, non-toxic and odorless material. 2. Production process: Polypropylene fibers are bonded together through a hot pressing or hot rolling process. 3. Fiber structure: The fiber is fine and the structure is even. 4. Physical properties: High softness, breathability and moisture absorption. 5. Purpose: Widely used in disposable hygiene products, medical hygiene, home decoration and other fields. 3. The difference between spunbonded nonwoven fabrics and PP nonwoven fabrics 1. Production process: Spunbonded non-woven fabrics use melt spinning technology, while PP non-woven fabrics are produced through hot pressing or hot rolling processes. 2. Raw materials: Spunbonded non-woven fabrics have many types of raw materials, such as polyethylene, polypropylene, etc., while PP non-woven fabrics mainly use polypropylene. 3. Fiber structure: The fibers of spunbonded non-woven fabrics are thicker and have a network structure, while the fibers of PP non-woven fabrics are delicate and have a uniform structure. 4. Performance characteristics: Spunbonded non-woven fabrics have high strength and tensile properties, wear resistance and tear resistance;PP non-woven fabrics have high softness, breathability and moisture absorption. 5. Application fields: Spunbonded non-woven fabrics are widely used in packaging, disposable supplies, building materials and other fields;PP non-woven fabrics are mainly used in disposable hygiene products, medical hygiene, home decoration and other fields. IV. Conclusion To sum up, there are obvious differences between spunbonded nonwovens and PP nonwovens in terms of production processes, raw materials, fiber structure, performance characteristics and application fields. Which nonwoven product to choose should be decided based on specific needs and application scenarios. For example, for areas that require higher strength and wear resistance, such as packaging materials, spunbonded nonwovens may be more suitable; while for areas that require softness, breathability and moisture absorption, such as disposable hygiene products, PP nonwovens may be more suitable. Fuzhou Henghua New Materials Co., Ltd. focuses on producing pp non-woven fabrics and other series products.

  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.
