【Product performance】
(1) light weight
Polypropylene fiber density of 0.90-0.92 g / cm3, in all chemical fiber is the lightest, 20% lighter than nylon, 30% lighter than polyester, 40% lighter than viscose fiber, it is suitable for winter clothing Such as skiswear or ski suits, mountaineering suits and other fabrics.
(2) high strength, good elasticity, wear resistance, corrosion resistance
High strength (dry, wet the same), is the manufacture of fishing nets, cable ideal material; wear resistance and resilience, and strength and polyester and nylon similar to the rebound rate with nylon, wool comparable to the polyester Lun, viscose fiber is much larger; polypropylene's dimensional stability is poor, easy to play and deformation, anti-microbial, no boring; chemical resistance is better than the general fiber.
(3) with electrical insulation and warmth
Polypropylene fiber resistivity is very high (7 × 1019Ω.cm), thermal conductivity is small, compared with other chemical fibers, polypropylene electrical insulation and warmth of the best, but easy to produce static electricity.
(4) heat resistance and aging resistance is poor
Polypropylene fiber low melting point (165 ~ 173 ℃), the stability of light and heat is poor, so the heat resistance of polypropylene, aging resistance is poor, impatient ironing. But can be added by adding anti-aging agent in the spinning to improve its anti-aging properties.
