Where is the market competitiveness of polypropylene high-strength yarn?

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 has low investment, raw materials are cheap, energy consumption is minimal, environmental pollution is less, and it has obvious technical and economic advantages.

Main properties of polypropylene high-strength yarn:

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

2. The density of polypropylene is 0.919 / cm ’, which is the lower 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, the cost of using polypropylene high-strength yarn as raw material will be much lower than that of polyester or nylon industrial yarn. In addition, due to its low moisture absorption (MO.1%), it is particularly suitable for marine products and other products that do not require moisture absorption.

3. Good wear resistance and flexibility.

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

5. Good stability to chemicals. Because there is no active group in the molecular structure of polypropylene, the stability to acids, alkalis and other chemicals is very good, even better than polyester and nylon, so it is suitable for many chemical fields.
