The modern society has developed. After the increase in life, it will pay attention to some things around you, and you will start with some things like you. It is expected a quality, good elasticity, good chemical stability, low manufacturing cost, and recirculation performance. There is also a good dyeing performance, dimensional stability, halvingness, soft feeling, comfortable and colorful taking fabrics. Then the polypropylene short fiber has the characteristics of light, good elasticity, good chemical stability, low manufacturing cost, simple recirculation processing, etc. Transfer, keep the skin dry, in commonly used fibers, its thermal conductivity is the lowest, even lower than wool, is an ideal warm material. The polypropylene has a strong anti-fouling and deodorant ability, small up, and its hydrophobic properties result in antibacterial, non-toxic, not mold and anti-microorganisms. Therefore, polypropylene can be applied to the manufacture of functional sportswear, fashion fabrics, sanitary materials, and the like. However, generally polypropylene has no high crystalline structure, it is not easy to perform yarn dyeing, fabric dyeing, can only be color mother particles, so color is not rich, so that the yarn, fabric dyeing range is limited, constrained polypropylene staple fibers in textile Application in the field of clothing.

Premium performance of polypropylene staple fibers

Polypropylene staple fiber with polyamide fibers, polyester fiber light, viscose fiber light, etc. have their own advantages, polypropylene short fibers are mainly raw materials with polypropylene resins, after melt spinning, drafting, curl, drying stereotype , Packages and other process processes are colored and colorless, and they specify the fluffy fibers of the number and length.

So the polypropylene staple fiber has those quality performance? Light, the density is 0.9 ~ 0.92 g / ccC, which is the lightest in all synthetic fibers, which is 20% lighter than the polyamide fiber, 30% lighter than the polyester fiber, 40% minus the viscous fiber; intensity; High (dry state and wet state), wear resistance and return elasticity; anti-microorganisms, not mildew; chemical resistance is also superior to general synthetic fibers. Further, compared with other synthetic fibers, the electrical insulation and warmth of polypropylene fibers is preferably, its resistivity is high (7 × 1019 ohm, cm), and the thermal conductivity is small.

However, the polypropylene short fiber has a low melting point (165 ~ 173 ° C), poor light, thermal stability, sooth polypropylene fiber heat resistance, poor aging resistance, usually takes the addition of heat stabilizers and anti-aging agents to improve their performance. Its hygroscopicity and dyeness are the worst in the synthetic fibers, and the slot margin is less than 0.03%, and the ordinary dyes cannot be colored, and therefore, in the spinning, a quantity of coloring masterbills are added to the raw material polypropylene. Coloration.
