Why is the application of polypropylene high strength yarn so extensive? Let's take a look today!

Polypropylene high strength yarn is widely used in all walks of life because of its many excellent characteristics. First of all, the strength of polypropylene high-strength silk is extremely high, comparable to polyester and polyamide industrial silk, and is not affected by humidity, maintaining the same strength under wet and dry conditions. Secondly, it has an extremely low density and is the lightest of all industrial synthetic fibers, only 66% of polyester and 80% of polyamide, which makes polypropylene high-strength fibers more portable in application.

In addition, polypropylene high strength yarn has excellent wear resistance, flat wear resistance is second only to nylon, and has significant stability to inorganic acids and alkali. At the same time, it is almost non-hygroscopic, the shrinkage rate of the fabric is small, and it has the effect of sweating and quick drying, which is very suitable for making swimsuits, diving suits and so on.

Polypropylene high strength yarn also has good aging resistance, not easy to be attacked by insects and bacteria, excellent chemical resistance, even better than polyester and nylon, making it suitable for chemical industry, environmental protection, food and other fields. Its application scope covers fire hose, sling, safety belt, conveyor belt, woven geotextile, industrial thread, cable, industrial filter cloth, fishing nets, building reinforcement materials, packaging materials, etc.

Due to the simple production process, low cost and excellent performance of polypropylene high-strength yarn, it has become a very competitive fiber raw material in the field of industrial silk, widely replacing traditional materials such as polyamide and polyester. Therefore, polypropylene high-strength yarn plays an indispensable role in modern industry and daily life.
