1.其实聚酯纤维就是涤纶，它的仿丝绸感强、光泽明亮，但不够柔和，具有闪光的效果，但是具有手感滑爽、平挺、弹性好，手捏紧绸面后松开无明显折痕，经、纬沾水后，不易扯断的特性。

In fact, 1. polyester fiber is polyester, its silk like sense of strong, bright and shiny, but not soft, with flash effect, but has a smooth feel, very flat, good elasticity, hand pinch silk surface after release no creases, warp and weft count, characteristic is not easy to break.

2. 锦纶就是通常说的尼龙纤维，是把尼龙材料拉成很细的纤维，再织布而成的，尼龙的具体学名叫做聚酰胺。光泽较暗淡，表面摸起来有一层蜡的感觉，色彩不鲜艳。手感硬挺，手捏紧面料后松开，有折痕，能缓慢恢复原状。经、纬纱牢度大。腈纶是聚丙烯腈纤维在我国的商品名，国外则称为“奥纶”、“开司米纶”。通常是指用85%以上的丙烯腈与第二和第三单体的共聚物，经湿法纺丝或干法纺丝制得的合成纤维。丙烯腈含量在35%～85%之间的共聚物纺丝制得的纤维称为改性聚丙烯腈纤维锦纶，学名聚酰氨纤维，是中国所产聚酰胺类纤维的统称，强度高.耐磨性,回弹性好，可以纯纺和混纺作各种衣料及针织品。

2. nylon is usually called nylon fiber, the nylon material is drawn into very fine fiber, and then woven, the specific name of nylon is called polyamide. The luster is dim, the surface feels a layer of wax, and the color is not bright. Feel stiff, hand pinch fabric loosen, creased, slowly recovered. The fastness of the warp and weft is large. Acrylic is polyacrylonitrile fiber in China's foreign trade name, is called "used" and "Cashmere fiber". It usually refers to a synthetic fiber produced by a copolymer of more than 85% acrylonitrile and second and third monomers by wet spinning or dry spinning. The acrylonitrile content in 35% ~ 85% between the copolymer spinning fiber called modified polyacrylonitrile fiber nylon, polyamide fiber name, is referred to as Chinese, produced by polyamide fiber. The wear resistance of high strength, good elasticity, can be pure and blended spinning for a variety of clothing and fabric needle.
