* Polyamide mutifilament chemical called polyamide,China's commodity called polyamide mltifilament also called nylon.
* The stability of the alkali,best in 10% concentration of caustic soda solution impregnation 100 h,basic don't reduce the fiber strength and the effect of ammonia water is also stable.
* Density of 1.12-1.14 g/cm³
* Melting point is 215-220℃, softening point is 160-180℃
* High resilience, when 100% elongation, rebound 3%
* Wear-resisting performance is best.
* Uv protection performance is good.
* Breaking elongation(%): 14-28
