人造纤维有粘胶纤维、醋酯纤维、铜铵纤维和蛋白纤维等多种,它们都是纺织的好原料。其中象粘胶纤维,在我国目前人造纤维工业中,已占据重要的地位。粘胶纤维是以天然纤维素为原料制成的。比如造纸用的木材、棉短绒、芦苇、甘蔗渣、高粱杆、龙须草、小麦杆、蓖麻杆、棉杆和稻草等,都可以用来造粘胶纤维。在制造过程中,一般都要把天 Man-made fibers include viscose fibers, acetate fibers, cuproammonium fibers, and protein fibers, which are all good raw materials for textiles. Among them, viscose fiber has occupied an important position in China’s current man-made fiber industry. Viscose fibers are made from natural cellulose. For example, wood used for papermaking, cotton linters, reeds, bagasse, sorghum rods, rushes, wheat straws, ramie rods, cotton stalks, and rice straw can all be used to make viscose fibers. In the manufacturing process, generally have to put the day
