Polyamide is the generic name of polyamide fiber produced in China. Internationally, it is called nylon. High strength. Abrasion resistance, good resilience. It can be spun and blended for various garments and knitted products. The main varieties are nylon 6 and nylon 66, whose physical properties are similar. Nylon is better than polyester in moisture absorption and dyeing, and it is resistant to alkali but not acid, and its fiber strength will decrease when exposed to sunlight for a long time. Nylons have heat setting property, which can keep the bending deformation formed when heated. The performance of nylon fabric is strong and wear-resistant.

Its abrasion resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber, so its durability is good. The elasticity and elastic recovery of nylon fabric is very good, but it is easy to deform under small external force, so its fabric is easy to become wrinkled in the process of wearing. The moisture absorption of nylon fabric is better in synthetic fabrics, so the clothing made of nylon is more comfortable than polyester clothing. Heat and light resistance are not good enough, ironing temperature should be controlled at 140 ℃ or less.

In the process of wearing and using must pay attention to the conditions of washing and maintenance, so as not to damage the fabric. Nylon fabric is a light fabric, only after polypropylene and acrylic fabric in synthetic fiber fabric, so it is suitable for making mountain climbing clothes, winter clothes, etc. Nylon fabric use nylon filament can be made into elastic silk, short silk can be blended with cotton and acrylic to improve its strength and elasticity.

Besides the application in clothing and decoration, it is also widely used in industry such as cordage, transmission belt, hose, rope, fishing net, tire, parachute, etc.
