What are the performance characteristics of polypropylene engineering fibers?

(1) Light weight

Polypropylene fiber has a density of 0.90-0.92 g/cm3, which is 30% lighter than polyester and 40% lighter than viscose fiber, so it is very suitable for fabrics for winter clothing, such as flocking fillers or ski suits and mountaineering suits.

(2) High strength, good elasticity, wear resistance and corrosion resistance

Polypropylene has high strength (same in dry state and wet state), and is an ideal material for manufacturing fishing nets and cables; it has good wear resistance and resilience, strength is similar to polyester and nylon, and its rebound rate is comparable to nylon and wool.

(3) With electrical insulation and thermal insulation

polypropylene engineering fibers has high electrical resistivity (7×1019Ω.cm) and small thermal conductivity. Compared with other chemical fibers, polypropylene has good electrical insulation and thermal insulation, but it is prone to static electricity during processing.

Shandong Zhiwei Chemical Fiber Products Co., Ltd. was established in 2003. After several years of hard work, it has developed into a professional large-scale polypropylene chemical fiber company integrating production and sales. The main products are: polypropylene yarn, polypropylene yarn, polypropylene fiber Medium-strength yarn, polypropylene high-strength yarn, high-strength polypropylene yarn, polypropylene rope, safety net, polypropylene engineering fibers, polypropylene mesh fiber, polyester fiber.
