PP Staple Fiber

Polypropylene staple fiberis divided into long fiber, short fiber, spunbonded non-woven fabric, melt-blown non-woven fabric and other four main types. It is a synthetic fiber spun from isotactic polypropylene obtained from propylene polymerization, and PP staple fiber name is polypropylene in China. Different products in the application industry play different roles, the main characteristics are light texture, high strength, good elasticity, wear resistance, corrosion resistance, improve luster, enhance hand feel, increase softness, improve drape. It has electrical insulation and warmth, but its hygroscopic and dyeing properties are slightly poor, and it is generally used in combination with other materials. PP staple fiber can be used in building materials, textile industry, decorative building materials, nonwovens, medical and health materials and cigarette filters. Most of the production process adopts porous, low speed and continuous process, namely short spinning process. PP staple fiber and cotton blend, can be made into cotton cotton muslin, bed sheets, that is, fiber and viscose blend can be made into blankets, polypropylene pure spinning and blending wool, polypropylene blankets, carpets, polypropylene cotton wool filter for smoke.

What are polypropylene fibers made of?

Polypropylene (PP) is a thermoplastic "additive polymer" made from a combination of propylene monomers. Plastic components are used in a variety of applications in industries as diverse as consumer packaging, automotive and textiles.

By adding PP fibers to cement mortar, the weight or volume of the mortar does not increase or settle. These fibers are a good substitute for hot steel reinforcement in concrete. We can add polypropylene fibers in short and separated forms to various forms of concrete.

PP fibers are also used for plastic strength. By adding them to plastics, cracking of plastics due to impact or cracking due to humidity and temperature changes can be reduced.
