Among the industrial yarns of various synthetic fibers, the high strength and impact resistance of polypropylene high-strength yarn, as well as its flexibility and chemical resistance, make it a very competitive variety. In addition, it has low investment in production equipment, cheap raw materials, minimal energy consumption, and low environmental pollution, and has obvious technical and economic advantages.

Properties of polypropylene high-strength yarn:

1. The strength of polypropylene high-strength yarn is comparable to that of polyester and nylon industrial yarns, and the strength is exactly the same in dry and wet conditions

2. The density of polypropylene is 0.919 / cm ′, which is the smallest density among all industrial synthetic fibers. Its density is only equivalent to 66% of polyester (1.389 / cma) and 80% of nylon (1.149 / cm3). Considering the price and density of silk, using polypropylene high-strength yarn as raw material will cost much less than polyester or nylon industrial yarn. In addition, because polypropylene absorbs little moisture (MO.1%), it is especially suitable for marine products and other products that do not require moisture absorption.

3.Good abrasion resistance and flexibility

4. Resistant to mildew. Polypropylene is not attacked by insects and bacteria.

5. Good stability to chemicals. Because polypropylene has no active groups in its molecular structure, it has very good stability to acids, alkalis, and other chemicals, and is even better than polyester and nylon, making it suitable for many chemical fields.

6. UV resistance and dyeability have been resolved. Polypropylene itself has poor light resistance, but by using polypropylene chips with stabilizers, it can achieve excellent resistance to degradation by ultraviolet radiation, and the product is suitable for outdoor use. Polypropylene dyeing is difficult, but it has been solved by adding dyeing aids or dope coloring.
