Application range of polypropylene staple fiber:

Polypropylene staple fiber is mainly used in needled carpet, automotive interior, non-woven fabrics, ropes, decorative materials, medicine and health products. Short fiber is also called cut fiber. Long bundles of chemical fibers are cut or drawn into fibers equal in length to the various natural fibers. Natural fibers such as whiskers and asbestos can also be used. The length of the staple fiber is generally 35 ~ 150mm. According to the specifications of natural fibers can be divided into cotton, wool, carpet and medium and long fibers. They can be spun pure or blended with different proportions of natural fibers or other fibers to make yarns, fabrics and felt.

Why can polypropylene staple fibers be used for automotive isolation materials

The legislative work of using polypropylene staple fiber to produce acoustic insulation materials for vehicles, and the formulation of more and more effective noise reduction detection method standards and product regulations have always been the research topic of the development of the automotive field. At present, the conventional measures to reduce the noise of automobiles include measuring the noise of automobiles and engines in anechoic chambers, and the design of air mufflers is to improve the combustion system, reduce the roughness of fuel injection and combustion, and improve the stiffness of structural parts such as cylinder blocks, especially body sheet metal parts. Soundproof material is sprayed on a large area of plates near the noise source, engine soundproof cover is installed, tire pattern design is improved, and soundproof material is installed inside the car.
