The characteristics and performance of polypropylene high-strength yarn.

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

2. density. The advantage of polypropylene fiber is that it is light in texture. Its density is only 0.91g/cm3, which is the lighter density variety among common chemical fibers. Therefore, polypropylene fiber of the same weight can obtain a higher coverage area than other fibers.

3. Strong extensibility. Polypropylene has high strength, large elongation, high initial modulus and excellent elasticity. Therefore, polypropylene high-strength yarn has good abrasion 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 moisture absorption, almost no moisture absorption, and the moisture regain rate under ordinary atmospheric conditions is close to zero. But it has a wicking effect and can transmit water vapor through the capillary in the fabric, but it does not have any absorption effect. Polypropylene fiber has poor dyeability and incomplete chromatograms, but the coloring of the original solution can be used to make up for the shortcomings.

5. Acid and alkali resistance. Polypropylene fiber 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 filter materials and packaging materials.

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

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