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.
