Regulation polypropylene synthetic fiber as raw silk is made of high-strength polypropylene, etc., with excellent crystallinity and good strength. Usually the strength of high-strength polypropylene yarn with synthetic fibers of polyester, nylon hair match.

Since the high-strength polypropylene yarn softness than the long-chain molecules, so its wear resistance and elasticity are very good, such as 3% elongation, elastic recovery rate of 96% to 100%. Thus, high-strength polypropylene silk costumes do not only durable and keeps its appearance, good dimensional stability. The proportion of high-strength polypropylene filament synthetic fiber is the lightest kind, lighter than water. High-strength polypropylene yarn no hydrophilic gene, so its moisture absorption is extremely small, so clothing made of poor ventilation, but easy to dry.

Precisely because of these characteristics of polypropylene, polypropylene high-strength wire is widely used, it will not mildew, rot and insects, and low prices.
