两种化学纤维化学纤維,包括人造纤維和合成纤維,正在世界紡織业中占着越来越重要的地位。五十多年前,人造纤维已經开始商业性的生产,合成纤維則仅有二十多年的历史。所謂人造纤維是由天然纤維素經过化学加工制成的纤維,而合成纤維則是完全用人工从极簡单而原始的材料,一步一步地合成类似天然纤維的材料。后者的出現,說明了人类已經有能力用不受自然条件 Two chemical fiber chemical fibers, including man-made fibers and synthetic fibers, are taking an increasingly important position in the world textile industry. More than fifty years ago, man-made fibers had begun commercial production, and synthetic fibers only had a history of more than two decades. The so-called artificial fiber is a fiber made of natural cellulose by chemical processing, and synthetic fiber is entirely artificially synthesized from a very simple and primitive material, step by step, similar to natural fiber materials. The appearance of the latter shows that human beings have the ability to use natural conditions
