粘胶和醋纤是人造纤维的主要品种。粘胶纤维是利用废棉、废木渣等天然纤维经过碱化而生成的碱纤维,再与二硫化碳作用生成纤维素黄原酸酯后经过纺丝处理而得到的纤维素大分子再生纤维,聚合度在300—600之间,在抽丝中由于自然收缩表面形成平行沟槽。醋纤是纤维素与醋酸酐反应而生成纤维素的二醋酸和三醋酸的衍生物,得到的是纤维醋酸酯纤维,也称醋酯纤维,聚合度在150—200之间,在抽丝
Viscose and vinegar fiber is the main varieties of man-made fibers. Viscose fiber is a cellulose macromolecule regenerated fiber obtained by spinning cellulose fiber using carbon fiber produced by alkali fiber generated from natural fiber such as waste cotton and waste wood residue and then reacted with carbon disulfide to polymerize Degree between 300-600, in the spinning due to the natural contraction of the surface to form parallel grooves. Vinegar fiber is the reaction of cellulose and acetic anhydride to produce cellulose diacetate and triacetate derivatives, fiber acetate fiber is obtained, also known as acetate ester fiber, the degree of polymerization between 150-200, in the spinning
