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, its production equipment investment is low, raw materials are cheap, energy consumption is minimal, environmental pollution is low, and it 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 wet and dry conditions

2. The density of polypropylene fiber is 0.919/cm’, which is the smallest among all industrial synthetic fibers. Its density is only 66% of polyester (1.389/cma) and 80% of nylon (1.149/cm3). Considering the price and density of the silk, the cost of using polypropylene high-strength silk as raw material will be much lower than that of polyester or nylon industrial silk. In addition, because polypropylene has low moisture absorption (MO.1%), it is especially suitable for marine products and other products that require non-hygroscopicity.

3. Good wear resistance and flexibility

4. Resistance to mildew. Polypropylene is not eroded by insects and bacteria.

5. Good stability to chemicals. Since polypropylene has no active groups in its molecular structure, it has very good stability to acids, alkalis and other chemicals, 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 excellent resistance to ultraviolet radiation degradation can be achieved by using polypropylene chips with stabilizers. The product is suitable for outdoor use. It is difficult to dye polypropylene fiber, but it has been solved by adding dye auxiliaries or coloring the original liquid
