Mainly used in the synthesis of polyamide fiber, its most outstanding advantage is higher than all the other wear resistance is 10 times higher than the cotton fiber, wear resistance, 20 times higher than in the wool blended fabric slightly adding polyamide fiber, can greatly improve the wear resistance; when stretched to 3-6%, elastic recovery rate can up to 100%; through tens of thousands of times the folding deflection without rupture.

    The strength of polyamide fiber is times higher than that of cotton and 4-5 times higher than that of wool, which is about 3 times of that of viscose fiber. But the polyamide fiber, heat resistance and light resistance is poor, also to maintain the poor clothes made of polyester as crisp. In addition, for clothing and nylon -66 nylon -6 has hygroscopicity and dyeing the shortcomings of the poor, for the development of new varieties of polyamide fiber polyamide fiber, nylon -3 and nylon -4, with light weight, good wrinkle resistance and good air permeability and good durability, dyeing and heat setting etc. Therefore, is considered to be very promising.

    This kind of products are widely used, is a good material of plastic and steel, iron, copper and other metals, is an important engineering plastics; wear resistant parts of cast nylon instead of a wide range of machinery and equipment, instead of copper and alloys for wear-resistant equipment. Applicable to the production of wear-resistant parts, transmission parts, household electrical appliances parts, auto parts, screw rod to prevent mechanical parts, chemical machinery parts, chemical equipment. Such as turbine, gear, bearing, impeller, crank, dashboard, drive shaft, blades, valves, screw, high pressure washers, screws, nuts, sealing ring, shuttle, sleeve, sleeve connector etc.
