近年来,国外化纤研究发展的新构思是要求制成成衣后穿着舒适、安全,而要提高这两项性能,往往需作化纤结构的改造。如粘胶和铜氨纤维的舒适性被再研究用来进入塑状结构;聚丙烯腈纤维触肤温暖而需进一步改善吸湿性;聚酰胺纤维应研究抗静电以改进触肤舒 In recent years, the new concept of foreign chemical fiber research and development is to require comfortable and safe clothing after being made into garments. To improve these two properties, it is often necessary to reform chemical fiber structures. For example, the comfort of viscose and cuprammonium fibers are re-researched to enter the plastic structure; the polyacrylonitrile fiber skin is warm and needs to improve the hygroscopicity; the polyamide fiber should be researched antistatic to improve the skin-skin comfort.
