Polyamide is mainly used for synthetic fibers. Its prominent advantage is that its wear resistance is higher than that of all other fibers, 10 times higher than cotton and 20 times higher than wool. Adding some polyamide fibers to blended fabrics can Greatly improve its wear resistance; when stretched to 3-6%, the elastic recovery rate can reach 100%; it can withstand tens of thousands of times of bending without breaking.
The strength of polyamide fiber is 1-2 times higher than that of cotton, 4-5 times higher than that of wool, and 3 times that of viscose fiber. However, the heat resistance and light resistance of polyamide fiber are poor, and the retention is not good, and the clothes made of it are not as crisp as polyester. In addition, both nylon-66 and nylon-6 used for clothing have the disadvantages of poor hygroscopicity and dyeability. For this reason, new polyamide fibers of nylon-3 and nylon-4 have been developed. Lightweight, excellent wrinkle resistance, good air permeability, good durability, dyeability and heat setting, etc., so it is considered to be promising.
This type of product has a wide range of uses, and is a good material for plastics to replace metals such as steel, iron, and copper. It is an important engineering plastic; cast nylon widely replaces wear-resistant parts of mechanical equipment, and replaces copper and alloys as wear-resistant parts of equipment. . It is suitable for making wear-resistant parts, transmission structural parts, household electrical appliances parts, automobile manufacturing parts, screw rod preventive mechanical parts, chemical mechanical parts, 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, sleeve connectors, etc.
Substitute copper and other metals
Because polyamide has non-toxic, light weight, excellent mechanical strength, wear resistance and good corrosion resistance, it is widely used to replace copper and other metals in the manufacture of bearings, gears, Pump blades and other parts. Polyamide has high strength after melt spinning and is mainly used as synthetic fiber and as medical suture.
Used in various medical and knitwear
For civilian use, it can be blended or purely spun into various medical and knitwear. Nylon filament is mostly used in knitting and silk industry, such as weaving monofilament stockings, elastic stockings and other wear-resistant nylon socks, nylon gauze scarves, mosquito nets, nylon lace, elastic nylon outerwear, various nylon silk or interwoven silk products. Nylon staple fibers are mostly used to blend with wool or other chemical fiber wool products to make various wear-resistant and durable clothing materials.
Nylon is widely used in the industry to make cords, industrial fabrics, cables, conveyor belts, tents, fishing nets, etc. In national defense, it is mainly used as parachute and other military fabrics.
