Overview of the performance characteristics of polypropylene fiber, today, the slightest margin of small with you understand:
(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.

(5) poor hygroscopicity and poor dyeing
Polypropylene fiber hygroscopicity and dyeing in the chemical fiber is the worst, almost no moisture, the moisture regain less than 0.03%. Fine denier polypropylene has a strong wicking effect, water vapor can be ruled out through the capillary in the fiber. After making clothing, clothing comfort is better, especially ultra-fine polypropylene fiber, due to surface area increases, can pass sweat faster, so that the skin to maintain a comfortable. As the fiber does not absorb moisture and shrinkage is small, polypropylene fabric with quick wash characteristics.

Polypropylene has poor dyeing, poor color, poor color fastness. Ordinary fuel can not make it stained, most of the colored polypropylene is used before the production of coloring. Can be used to color the liquid, fiber modification, in the melt spinning before mixing the fuel complexing agent.
