The polypropylene yarn is made of polypropylene and then spun into filaments after being polymerized to obtain polypropylene. Polypropylene yarn has the following characteristics.

1.High strength, polypropylene yarn generally has a breaking strength of 4.5 - 7g/d. This value is comparable to high-strength polyesters and polyamides in synthetic fibers. There is no loss of strength in the wet state.

2.Good wear resistance and elasticity. The abrasion resistance of polypropylene yarn is second only to nylon in chemical fiber. Elasticity at 3% elongation, the elastic recovery rate up to 96-1 %, so clothes made of polypropylene yarn is not only strong and durable, but the appearance of crisp, good dimensional stability.

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