What are the properties and advantages of  PP yarn?

The biggest advantage is that the texture is light, and its density is only 0.91g/cm3, which is the lightest of the common chemical fibers, so the same weight of polypropylene yarn can obtain higher coverage than other fibers. High-strength polypropylene has high strength, high elongation, high initial modulus and excellent elasticity, so polypropylene yarn has good abrasion resistance.

In addition, the wet strength of PP yarn is basically equal to dry strength, so it is an ideal material for making fishing nets and cables; hygroscopicity and dyeing properties are light and warm; almost no moisture absorption, but wicking ability is strong, and moisture absorption and perspiration are obvious; Polypropylene yarn has little hygroscopicity and is almost non-hygroscopic. The moisture regain under atmospheric conditions is close to zero.

At the same time, the PP yarn has good electrical insulation, but it is easy to generate static electricity during processing. Because the thermal conductivity of polypropylene yarn is small, the thermal insulation is good; the strength is high, the strength of polypropylene yarn is second only to nylon, but the price is only 1/3 of nylon; the fabric is stable in size, wear-resistant and elastic, and good in chemical stability. .

The advantages and performance of PP yarn are very obvious, and it is a powerful chemical fiber product.
