Analysis of the physical and chemical properties of polypropylene high-strength yarn!

1. Strong elongation polypropylene high-strength yarn has high strength, long elongation, high initial modulus and excellent elasticity. So polypropylene has good abrasion resistance. In addition, the wet strength of polypropylene is basically equal to the dry strength, so it is an ideal material for making fishing nets and cables.

2. Hygroscopicity and dyeability polypropylene high-strength yarn has very little hygroscopicity, almost no moisture absorption, and the moisture regain under general atmospheric conditions is close to zero. But it has a wicking effect, passing water vapour through the capillaries in the fabric, but does not have any absorption effect on its own. Polypropylene has poor dyeability and incomplete chromatogram, but it can be compensated by the method of dope dyeing.

3. Acid and alkali resistance polypropylene high-strength yarn has good chemical corrosion resistance, and polypropylene has good resistance to acid and alkali, so it is suitable for use as filter material and packaging material.

4. Light resistance, etc. polypropylene high-strength yarn has poor light resistance, poor thermal stability, easy aging, and is not resistant to ironing. However, its performance can be improved by adding an anti-aging agent during spinning. In addition, polypropylene has good electrical insulation, but it is easy to generate static electricity during processing.

Suining Tongjia Chemical Fiber Factory was founded in 2013. The main products are 300D-3000D high-strength polypropylene filament, polypropylene double-twisted yarn, polypropylene industrial yarn, high-strength polypropylene yarn, etc.
