How to distinguish dacron and polyamide fiber on a daily basisHow to distinguish dacron and polyamide fiber on a daily basis? Here's how to popularize it: Dacron imitate silk feels strong, burnish is bright, but not downy enough, have the effect of glint, feel is smooth, flat quite, flexibility is good. After hand knead silken surface loosen without apparent crease. After weft and warp are dipped in water, it is not easy to tear. Nylon luster is dim, the surface seems to be coated with a layer of wax feeling, color is not bright. Feel firm, the hand after squeezing the fabric loosen, there are creases, can be slowly restored to its original state. High fastness of warp and weft. Nylon properties: strength, good wear resistance, ranking the first of all fibers. Its wear 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. Nylon fabric has excellent elasticity and elastic recovery, but it is easy to be deformed under small external force, so its fabric is easy to be crumpled in the process of wearing. Poor ventilation and air permeability, easy to generate static electricity. The hygroscopicity of polyamide fiber is better among synthetic fiber fabrics, so the clothes made of polyamide fiber are more comfortable than those made of polyester. Good corrosion resistance and corrosion resistance. Heat and light resistance is not good enough, ironing temperature should be controlled below 140℃. Pay attention to the condition of washing and maintenance during wearing and using, so as not to damage the fabric. Polyamide fabric is a light fabric, and is only listed after polypropylene and acrylic fabric in synthetic fiber fabric. Therefore, it is suitable for making mountaineering clothing and winter clothing. Polyester performance: high strength. The strength of short fiber was 2.6 ~ 5.7cN/ Dtex, and that of high strength fiber was 5.6 ~ 8.0cN/ Dtex. Due to its low hygroscopicity, its wet strength and dry strength are basically the same. The impact strength is 4 times higher than that of nylon and 20 times higher than that of viscose. Good elasticity. Elasticity close to wool, when stretched at 5% ~
