Polyamide generally refers to nylon、 and the emergence of nylon has transformed the appearance of textiles. Its synthesis is a major breakthrough in the synthetic fiber industry and also a very important milestone in polymer chemistry. Polyamide is mainly used for synthetic fibers、 and its most prominent advantage is that its wear resistance is higher than all other fibers、 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to blended fabrics can greatly improve their wear resistance; When stretched to 3-6%、 the elastic recovery rate can reach ; Can withstand tens of thousands of twists and turns without breaking. The strength of polyamide fibers is 1-2 times higher than cotton、 4-5 times higher than wool、 and 3 times higher than viscose fibers. However、 polyamide fibers have poor heat and light resistance、 as well as poor retention、 resulting in clothes that are not as crisp as polyester. In addition、 both nylon 66 and nylon 6 used for clothing have the disadvantages of poor moisture absorption and dyeing properties. Therefore、 a new variety of polyamide fibers、 nylon 3 and nylon 4、 has been developed、 which have the characteristics of light weight、 excellent wrinkle resistance、 good breathability、 good durability、 dyeing properties、 and heat setting. Therefore、 they are considered to have great development prospects. This type of product has a wide range of uses and is a good material for replacing metals such as steel、 iron、 and copper with plastics. It is an important engineering plastic; Cast nylon is widely used as a wear-resistant component in mechanical equipment、 replacing copper and alloys as wear-resistant parts. Suitable for making wear-resistant parts、 transmission structure parts、 household appliance parts、 automotive manufacturing parts、 screw prevention mechanical parts、 chemical machinery parts、 and chemical equipment. Such as turbines、 gears、 bearings、 impellers、 cranks、 instrument panels、 drive shafts、 valves、 blades、 screw rods、 high-pressure washers、 screws、 nuts、 sealing rings、 shuttles、 sleeves、 shaft sleeve connectors、 etc. Due to its non-toxic、 lightweight、 excellent mechanical strength、 wear resistance、 and good corrosion resistance、 polyamide is widely used as a substitute for copper and other metals in the manufacturing of bearings、 gears、 pump blades、 and other parts in industries such as machinery、 chemicals、 instruments、 and automobiles. Polyamide melt spun into silk has high strength、 mainly used as synthetic fibers and can be used as medical sutures. Used for various medical and knitted products in civilian use、 it can be blended or pure spun into various medical and knitted products. Nylon filament is commonly used in the knitting and silk industry、 such as weaving single stockings、 elastic stockings and other wear-resistant nylon stockings、 nylon gauze、 mosquito nets、 nylon lace、 elastic nylon outerwear、 various nylon silk or interwoven silk products. Nylon short fibers are mostly used to blend with wool or other chemical fiber products to make various wear-resistant and durable clothing materials. In industry、 nylon is widely used in the production of cords、 industrial fabrics、 cables、 conveyor belts、 tents、 fishing nets、 etc. Mainly used as parachutes and other military fabrics in national defense
