Polypropylene high strength yarn manufacturers introduce what is polypropylene.

Polypropylene fiber is the name of polypropylene fiber, it is made of propylene as raw material by polymerization, melt spinning fiber. Its shape, the vertical surface is straight and smooth, and the cross-section is circular. The advantage of polypropylene is that it is light in texture, 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. Strong elongation, high strength, large elongation, high initial modulus, excellent elasticity. So polypropylene wear resistance 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. Hygroscopic and dyed polypropylene have very little hygroscopic properties, almost no hygroscopic properties, and the moisture regain rate under general atmospheric conditions is close to zero. However, it has a core suction effect, which can transfer water vapor through the capillary tubes in the fabric, but does not have any absorption effect itself. The dyeing property of polypropylene is poor and the chromatography is incomplete, but the method of stock solution coloring can be used to make up for the deficiency. Acid resistance and alkali resistance, polypropylene has good chemical resistance, in addition to concentrated nitric acid, concentrated caustic soda, polypropylene has good resistance to acid and alkali, so it is suitable for filter materials and packaging materials. Light resistance, polypropylene light resistance is poor, thermal stability is poor, easy to age, not resistant to ironing. However, the anti-aging properties can be improved by adding anti-aging agents during spinning. In addition, the electrical insulation of polypropylene is good, but it is easy to produce static electricity during processing.
