粘胶纤维的生产分为粘胶制造、纺絲、整理三大部分。原液车间生产供纺絲用的粘胶,粘胶是一种褐色有特殊气味的胶状物体。制造用的原料是浆粕(纸浆或棉浆),NaOH和CS_2。生产时先将浆粕浸于装NaoH溶液的漫渍机内浸硷,制成硷性纤维素,再经压榨、粉碎、老成、置于黄化鼓内加入CS_2(2200公斤硷性纤维素加CS_2 200公斤), Viscose fiber production is divided into viscose manufacturing, spinning, finishing three parts. The dope workshop produces viscose for spinning, and the viscose is a brown, jelly-like object with a special smell. Raw materials for manufacturing are pulp (pulp or cotton pulp), NaOH and CS_2. During the production, the pulp was immersed in alkali so as to impregnate the soaking pulp in a NaoH solution to prepare alkaline cellulose, which was crushed, aged and placed in a yellowing drum for adding CS_2 (2,200 kg of alkaline cellulose plus CS_2 200 kg),
