Today we will learn about the acid and alkali resistance of PP high-strength yarn.

Since 1957, with the technological advancement of spinning grade polypropylene and spinning technology, the output of polypropylene high-strength wire exceeded 5 million tons in 1996, accounting for 11.5% of synthetic fiber, which has received more and more attention in the development of chemical fiber in the world. . The longitudinal surface of the polypropylene high-strength yarn is straight and smooth with a circular cross section.

The biggest advantage of polypropylene in high-strength fiber density is its light weight. Its density is only 0.91g/cm3, which is the lightest of the common chemical fibers. Therefore, the same weight of polypropylene high-strength yarn can obtain higher coverage than other fibers.

Polypropylene has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, PP high-strength yarn has good resistance to acid and alkali, so it is suitable for use as filter materials and packaging materials. Light resistance, etc. His light resistance is poor, thermal stability is also poor, easy to age, not resistant to ironing.

PP high-strength yarn can be used not only for the production of carpets, but also for a wide range of decorative fabrics. It is characterized by bright colors, not easy to fade, and good antistatic effect. The polypropylene carpet yarn product can obtain the effect of imitation wool after extinction and twisting. It is suitable for the production of woven carpets. The carpet surface is similar to wool carpet, and the strip is full and resilience. Can be used in textiles, decorative fabrics, car blankets, carpet industry and many other fields.

Shanghai Jinci Industrial Co., Ltd. is a large-scale entity specializing in the production and sales of polypropylene (PP yarn).
