Performance characteristics (1) Lightweight Polypropylene fiber has a density of 0.90-0.92 g/cm3, which is the lightest among all chemical fibers, 20% lighter than nylon, 30% lighter than polyester, and 40% lighter than viscose fiber. Therefore, it is very suitable for use as a filler for winter clothing or as a fabric for skiing, hiking, and other clothing (2) High strength, good elasticity, wear resistance, and corrosion resistance Polypropylene fiber has high strength (the same in both dry and wet states), making it an ideal material for manufacturing fishing nets and cables; Good wear resistance and resilience, similar in strength to polyester and nylon, with a rebound rate comparable to nylon and wool, much higher than polyester and viscose fibers; Polypropylene has poor dimensional stability, is prone to pilling and deformation, is resistant to microorganisms, and is not moth prone; Chemical resistance is superior to general fibers (3) It has electrical insulation and warmth retention Polypropylene fiber has a high electrical resistivity (7 × 1019 Ω. cm), with a low thermal conductivity, polypropylene fiber has the best electrical insulation and warmth retention compared to other chemical fibers, but is prone to generating static electricity during processing (4) Poor heat and aging resistance Polypropylene fibers have a low melting point (165-173 ℃) and poor stability to light and heat. Therefore, polypropylene fibers have poor heat and aging resistance and are not resistant to ironing. . However, the anti-aging property can be improved by adding anti-aging agent during spinning(5) Poor hygroscopicity and dyeing properties Polypropylene fibers have the worst hygroscopicity and dyeing properties among chemical fibers, with almost no hygroscopicity and a moisture regain of less than 0.03%. . Fine denier polypropylene fiber has a strong wicking effect, and water vapor can be eliminated through the capillaries in the fiber. After being made into clothing, the comfort of the clothing is better, especially with ultrafine polypropylene fibers. Due to the increase in surface area, sweat can be transmitted faster, keeping the skin comfortable. Due to the non hygroscopic and low shrinkage of fibers, polypropylene fabrics have the characteristics of easy washing and quick drying Polypropylene fiber has poor dyeing properties, light color, and poor dyeing fastness. Ordinary fuels cannot dye it, and most colored polypropylene fibers are produced by pre spinning coloring. Raw material coloring and fiber modification can be used, and fuel complexing agent can be mixed before melt spinningFunction of testing report:1.
