What is pp line?

The pp line is spun into silk after being polymerized into polypropylene by using propylene as a raw material. The pp line has the following characteristics:

1. High strength.

The pp line generally has a breaking strength of 4.5 to 7 g/denier. This value is comparable to the high-strength varieties of polyester and nylon in synthetic fibers. There is no loss in strength during wet conditions.

2. Good wear resistance and elasticity.

The wear resistance of pp line is second only to nylon in chemical fiber. When the elasticity is 3%, the elastic recovery rate can reach 96%, so the clothes made of pp line are not only durable, but also have a firm appearance and good dimensional stability.

3. Light weight (0.91), corrosion resistance, acid and alkali resistance.
