Nylon and polyester, one difference
Polyester --- Polyester fiber, also known as POLYESTER, is characterized by good breathability and moisture removal. There is also a strong ability to resist acid, alkali and ultraviolet rays.
Nylon --- Nylon, also known as Nylon, polyamide fiber. The advantages are high strength, high wear resistance, high chemical resistance, good deformation resistance, and aging resistance. The disadvantage is that it feels hard.
Nylon and polyester, difference two
Polyester silk imitation has a strong feeling and bright luster, but it is not soft enough, has a flashing effect, and feels smooth, flat and flexible. After squeezing the silk surface, loosen it without obvious creases. After the warp and weft are dipped in water, it is not easy to break.
The gloss of nylon is dull, the surface is like a layer of wax, and the color is not bright. The hand feels stiff. After squeezing the fabric tightly, loosen it. There are creases, which can slowly restore the original state. The fastness of warp and weft is large.
Nylon and polyester, difference three
Nylon performance: strong, wear-resistant, ranking first among all fibers. Its abrasion resistance is 10 times that of cotton fiber, 10 times that of dry viscose fiber, and 140 times that of wet fiber. Therefore, its durability is excellent. The elasticity and elastic recovery of the nylon fabric are excellent, but it is easily deformed under a small external force, so the fabric is easily wrinkled during wearing. Poor ventilation and easy to generate static electricity. The hygroscopicity of nylon fabric is a better variety among synthetic fiber fabrics, so clothing made of nylon is more comfortable to wear than polyester clothing.
Has good resistance to decay and corrosion. The heat and light resistance are not good enough, the ironing temperature should be controlled below 140 ℃. Pay attention to the washing and maintenance conditions during wearing to avoid damage to the fabric. Nylon fabrics are light fabrics, which are only listed after polypropylene and acrylic fabrics in synthetic fiber fabrics. Therefore, they are suitable for mountaineering clothes and winter clothing.
Polyester performance: high strength. The short fiber strength is 2.6 to 5.7 cN / dtex, and the high strength fiber is 5.6 to 8.0 cN / dtex. Because of its low hygroscopicity, its wet strength is basically the same as its dry strength. The impact strength is 4 times higher than nylon and 20 times higher than viscose fiber. Good flexibility. The elasticity is close to wool, and when stretched by 5% to 6%, it is almost recoverable. The wrinkle resistance is better than other fibers, that is, the fabric is not wrinkled, and the dimensional stability is good. The elastic modulus is 22 ～ 141cN / dtex, which is 2 ～ 3 times higher than nylon.
Good water absorption. Good abrasiveness. The abrasion resistance is second only to the nylon with the best abrasion resistance, better than other natural fibers and synthetic fibers, and the light resistance is second only to acrylic. preservative. Resistant to bleach, oxidants, hydrocarbons, ketones, petroleum products and inorganic acids. It is resistant to dilute alkali and not afraid of mildew, but hot alkali can decompose it. Poor dyeing. Polyester fabric has poor hygroscopicity, wears a sultry feeling, and is easy to carry static electricity and dirt, which affects the appearance and comfort. However, it is very easy to dry after washing, and the wet strength hardly drops, does not deform, and has good washability. Polyester is the most heat-resistant fabric in synthetic fabrics, with a melting point of 260 ° C and an ironing temperature of 180 ° C.
It has thermoplasticity and can be made into a pleated skirt with long pleats. At the same time, the polyester fabric has poor resistance to melting, and it is easy to form holes in the case of soot and sparks. Therefore, you should try to avoid contact with cigarette butts and sparks. Polyester fabrics have good light resistance. In addition to being inferior to acrylic, their lightfastness is better than natural fiber fabrics. Especially the light resistance behind the glass is very good, almost comparable to acrylic. Polyester fabric has good resistance to various chemicals. It is not damaged by acids or alkalis, and it is not afraid of mold or worms. Polyester fabric has good wrinkle resistance and shape retention, so it is suitable for coats.
