(2) High strength, good elasticity, abrasion resistance, corrosion resistance, high strength of polypropylene fiber (same in dry and wet state), is the ideal material for fishing nets and cables; good wear resistance and resilience, strength and polyester and nylon are similar, resilience can be comparable to nylon and wool, much larger than polyester and viscose fibers; Poor quality, easy pilling and deformation, anti-microbial, moth-free; chemical resistance is better than general fibers.
(3) Polypropylene fibers have high resistivity (7 *1019_.cm) and low thermal conductivity. Compared with other chemical fibers, polypropylene fibers have the best electrical insulation and thermal insulation, but they are prone to static electricity during processing.
(4) The heat resistance and ageing resistance of polypropylene fibers are poor, the melting point of polypropylene fibers is low (165-173 C), and the stability of light and heat is poor. Therefore, the heat resistance and ageing resistance of polypropylene fibers are poor and ironing resistance is not good. But the anti-aging property can be improved by adding anti-aging agent in spinning.
(5) poor hygroscopicity and dyeability
