What are the physical and chemical properties of polypropylene high-strength yarn?


1. form. The main raw material of polypropylene high-strength yarn is polypropylene. The longitudinal surface of polypropylene is flat and smooth, and the cross section is round.

2. density. The advantage of polypropylene is its light texture. Its density is only 0.91g / cm3, which is a lighter density among common chemical fibers, so polypropylene with the same weight can get a higher coverage area than other fibers.

3. Strong stretch. Polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene high-strength silk has good wear resistance. In addition, the wet strength of polypropylene is basically equal to the dry strength, so polypropylene high-strength yarn is an ideal material for making fishing nets and cables.

4. Hygroscopicity and dyeability. Polypropylene has very little hygroscopicity and hardly absorbs moisture. Under normal atmospheric conditions, the moisture regain is close to zero. But it has a wicking effect and can transfer water vapor through the capillary in the fabric, but it does not have any absorption effect itself. Polypropylene has poor dyeability and incomplete chromatograms, but it can be compensated by the method of coloring the original solution.

5. Acid and alkali resistant. Polypropylene has good chemical resistance. In addition to concentrated nitric acid and concentrated caustic soda, polypropylene high-strength yarn has good resistance to acids and alkalis, so it is suitable for use as a filter material and packaging material.

6. Light resistance, etc. Polypropylene has poor light resistance, poor thermal stability, easy aging, and is not resistant to ironing. But by adding anti-aging agent during spinning.


The above is the physical and chemical properties of polypropylene high-strength yarn.
