The difference between polyester and nylon, polyester---polyester fiber, also known as POLYESTER, is characterized by good air permeability and moisture removal. There is also strong resistance to acids and alkalis, and UV resistance. Nylon---Nylon is also called Nylon, polyamide fiber. The advantages are high strength, high wear resistance, high chemical resistance and good deformation resistance and aging resistance. The disadvantage is that it feels hard. How to distinguish between the two? Polyester has a strong sense of silk-like texture and bright finish, but it is not soft enough to have a flashing effect, smooth, flat and elastic. After squeezing the silk surface tightly, loosen it without obvious crease. After the warp and weft are wetted with water, they are not easy to tear. Nylon finish is relatively dull, the surface feels like a layer of wax, and the color is not bright. The hand feels stiff, and the fabric is loosened after squeezing it tightly. There are creases and can slowly return to its original shape. High fastness of warp and weft.
Nylon performance: strong, good abrasion resistance, ranking first among all fibers. Its abrasion resistance is 10 times that of cotton fiber. Therefore, its durability is excellent. Nylon fabric has excellent elasticity and elastic recovery, but it is easy to deform under a small external force, so its fabric is easy to wrinkle during wearing. Poor ventilation and easy to generate static electricity.
The hygroscopicity of nylon fabric is a better variety among synthetic fiber fabrics, so work clothes made of nylon are more comfortable to wear than polyester work clothes. It has good resistance to moth and corrosion. The heat resistance is not good enough, the ironing temperature should be controlled below 140℃. Pay attention to the conditions of cleaning and maintenance in the process of wearing and using, so as not to damage the fabric. Nylon fabric is a light fabric, which is only listed after polypropylene and polyacrylonitrile fabrics in synthetic fabrics. Therefore, it is suitable for making ski wear and winter work wear.
Polyester performance: high strength. Due to its low hygroscopicity, its wet strength and dry strength are basically the same. The impact resistance is 4 times higher than nylon and 20 times higher than viscose fiber. Good flexibility. The elasticity is close to that of wool, and it can almost completely recover when it stretches 5% to 6%. The wrinkle resistance is better than other fibers, that is, the fabric does not wrinkle and has good dimensional stability. The elasticity is 2 to 3 times higher than that of nylon. Good water absorption. Good grindability. The abrasion resistance is second only to the best abrasion resistance of nylon, better than other natural fibers and synthetic fibers, and the durability is second only to polyacrylonitrile fibers. preservative. It is resistant to bleaching agents, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. It is resistant to dilute alkali, not afraid of mildew, but hot alkali can make it decompose. Poor colorability.
Polyester fabric has poor hygroscopicity and has a stuffy feeling when worn. At the same time, it is easy to be charged with static electricity and contaminate dust, which affects appearance and comfort. However, it is very easy to dry after washing, and the wet strength hardly drops, does not deform, and has good wash and wear properties. Polyester is the most heat-resistant fabric among synthetic fabrics, with a melting point of 260°C and an ironing temperature of 180°C. With thermoplasticity, it can be made into pleated skirts with long-lasting pleats. At the same time, polyester fabrics have poor melting resistance and are prone to forming holes in the presence of soot and sparks. Therefore, you should avoid contact with cigarette butts, sparks, etc. when wearing. The durability of polyester fabric is better, except that it is worse than polyacrylonitrile fiber, its light fastness is better than natural fiber fabric. Especially the light fastness behind the glass is very good, almost on par with polyacrylonitrile fiber. Polyester fabric has good resistance to various chemicals. Acids and alkalis do not damage it too much, and they are not afraid of molds and insects. Polyester fabric has good wrinkle resistance and shape retention, so it is suitable for outerwear.
