What material is PP yarn? What does PP yarn contain?

The chemical molecules of PP yarn are also very different, and are made of polypropylene fibers. Polypropylene has good heat resistance, and its density is only 0.91g/cm3, which is a light density variety of common chemical fibers, so the same weight of polypropylene has a higher coverage area than other fibers.

What material is PP yarn

What is PP yarn? PP yarn raw material; About the introduction of PP yarn, we start with its big point. The advantage of large is light texture, its density is only 0.91g/cm3 is a common chemical fiber of light density varieties, so the same weight of polypropylene than other fibers to get a higher coverage area. The tensile polypropylene fiber has high strength, large elongation, high initial modulus and excellent elasticity. So the wear resistance of polypropylene is good; In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is the ideal material for making fishing nets and cables; Hygroscopicity and dyeability, light quality and good heat preservation; Almost no moisture absorption, but the core absorption ability is very strong, moisture absorption and sweating effect is obvious; The hygroscopic property of polypropylene is very small, almost non-hygroscopic, and the moisture regain rate under general atmospheric conditions is close to zero. In addition, the electrical insulation of polypropylene is good, but it is easy to produce static electricity during processing. Because the thermal conductivity of polypropylene is small, the heating property is good; High strength polypropylene filament strength is second only to nylon, but the price is only 1/3 of nylon; The size of the fabric is stable, the wear resistance and elasticity are good, and the chemical stability is good.

Dongguan Donghong New Material Co., Ltd. Founded in 1991, located in Wentang Brick Kiln 冚 Industrial Zone, Dongcheng District, Dongguan City, Guangdong Province, is a medium-sized enterprise specializing in the production of various types of polypropylene yarn, with more than 800 employees. At present, our company has 16 polypropylene filament yarn production lines, forming an annual output of 20,000 tons of polypropylene yarn production scale.
