Polypropylene staple fiber can be divided into cotton type, wool type, carpet type and medium and long type short fibers according to the specifications of natural fibers. They can be spun purely or blended with natural or other fibers in varying proportions to make sliver, fabric and felt. For example, general-grade pitch carbon fiber is cut into 150mm long, 15μm in diameter, carbon fiber with a strength of 800MPa and a modulus of 41GPa, and mixed with phenolic carbon fiber (length 70mm, strength 200MPa, diameter 14μm) in a ratio of 8:2 to obtain Stable and uniform sliver. Woven into various shapes of fabrics or chopped fibers for reinforcement of composite materials such as cement and aluminum alloys.

Features of polypropylene staple fiber: polypropylene staple fiber has low density, light weight, and can float on the water; polypropylene yarn has high strength and strong tensile strength; polypropylene staple fiber has certain acid and alkali resistance and corrosion resistance, even if soaked Don't worry about it in sea water; polypropylene staple fiber has low hygroscopicity and almost no moisture absorption; polypropylene staple fiber is an environmentally friendly and pollution-free product.

Polypropylene staple fiber is made of polypropylene through the processes of melting, drawing, spinning and cutting. In the process of making polypropylene staple fibers, functional masterbatches, such as anti-aging masterbatches, flame retardant masterbatches, etc., can be added as needed to increase the performance of polypropylene staple fibers. Polypropylene staple fiber for felt is a polypropylene staple fiber specially used for making felt, which is used for filter material.
