Why do you choose polypropylene staple fiber as the acoustic insulation material?

First, let's look at the characteristics of polypropylene staple fiber:

1. Polypropylene staple fiber has excellent moisture conductivity, flexibility, mesh combing, excellent thermal adhesion.

2. Polypropylene staple fiber has high strength, strong crimping elasticity, light weight, low melting point, good surface permeability, acid and alkali resistance and wear resistance better than other fibers;

It has been a research topic in the field of automobile development to legislate more and more effective noise reduction detection method standards and product regulations on the production of vehicle sound absorption and sound insulation materials using polypropylene staplet fiber. At present, the conventional measures to reduce automobile noise include measuring the noise of automobile and engine in anechoic chamber. The design of air muffler is to improve the combustion system, reduce the roughness of fuel injection and combustion, and improve the stiffness of cylinder block and other structural parts, especially the sheet metal parts of the body. A large area of plates near the noise source should be sprayed with soundproof materials, the engine soundproof cover and the tire pattern design should be improved, and soundproof materials should be installed in the car.

Application scope of polypropylene staple fiber:

Polypropylene staple fiber is mainly used for acupuncture carpet, automobile interior, non-woven fabric, rope, decorative materials, medical and health care products, etc. Staple fiber is also called cut fiber. Long bundles of chemical fibers are cut or drawn into fibers of the same length as the various natural fibers. Natural fibres such as whiskers and asbestos can also be used. The length of staple fiber is generally 35 ~ 150mm. According to the specification of natural fiber can be divided into cotton, wool, carpet and long and short fiber. They can be spun pure or blended with natural or other fibers in different proportions to make yarns, fabrics, and felt.
