The basic properties of high-strength polypropylene yarns are revealed!

1. high-strength polypropylene yarn form: The longitudinal direction of polypropylene is flat and smooth, and the cross section is round.

2. high-strength polypropylene yarnn stretchability: polypropylene fiber has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene has good wear resistance. In addition, the wet strength of polypropylene filaments is basically equal to dry strength.

3. high-strength polypropylene yarn hygroscopicity and dyeability: Polypropylene high-strength yarn has little hygroscopicity and hardly absorbs moisture. The general moisture regain rate under atmospheric conditions is close to zero. However, it has a wicking action and can transfer water vapor through the capillary in the fabric, and does not have any absorption by itself. High-strength polypropylene yarn has poor dyeability and incomplete chromatogram, but it can be used to make up for the lack of coloring.

4. high-strength polypropylene yarn is resistant to acid and alkali: polypropylene has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, polypropylene has good resistance to acid and alkali.

Suining Tongjia Chemical Fiber Factory's main products are 250D-3000D high-strength polypropylene yarn, polypropylene double-twisted yarn, polypropylene industrial yarn, high-strength polypropylene thread and so on. The product has high strength, light weight, small heat shrinkage, flame retardant, anti-aging, low thermal conductivity, etc. It is widely used in various industrial fabrics, cables, container bags, anti-crack engineering fibers and other products, sold throughout the country. And some exports.
