Raw material characteristics:
1. Lightweight, the lightest among all chemical fibers.
2. High strength, good elasticity, abrasion resistance, corrosion resistance, good abrasion resistance and resilience, the strength is similar to polyester, and the resilience rate is much larger than that of polyester; chemical resistance is better than ordinary fibers.
3. It has electrical insulation and warmth retention. Polypropylene fiber has a high electrical resistivity (7×1019Ω.cm) and low thermal conductivity. Compared with other chemical fibers, polypropylene has the best electrical insulation and warmth retention properties, but when processed Easy to generate static electricity.
4. Poor heat resistance and aging resistance, but it can be improved by adding anti-aging agents during spinning.
5. The hygroscopicity and dyeability are poor, and most of the colored polypropylene fibers are produced by coloring before spinning. It can be used for coloring, fiber modification, and blending with fuel complexing agent before melt spinning.
Polypropylene non-woven fabric use:
1. Used in disposable sanitary products, such as sanitary napkins, surgical gowns, caps, masks, bedding, diaper fabrics, etc. Sanitary napkins for women, disposable baby and adult diapers have now become common products that people consume daily.
2. The polypropylene fiber after chemical or physical modification can have various functions such as exchange, heat storage, electrical conductivity, antibacterial, deodorization, ultraviolet shielding, adsorption, desquamation, isolation selection, agglutination, etc. It will become an artificial kidney, Artificial lungs, artificial blood vessels, surgical thread and liquid absorbent gauze are important materials in various medical fields.
3. There is a growing market for labor protection clothing, disposable masks, disposable hats, surgical gowns, disposable bed sheet, pillowcases, mattress materials, etc.
