    • It is an object of the present invention to overcome the problem of fibrillation which is a drawback found in solvent-spun regenerated cellulosic fibers and to thereby provide high-quality regenerated cellulosic fibers. The regenerated cellulosic fibers are produced by the use of a spinning dope of cellulose dissolved in a solvent containing N-methylmorpholine N-oxide under the conditions that the average degree of polymerization of cellulose contained in the spinning dope is held to 400 or lower and 5% to 30% by weight of the cellulose is adjusted to a degree of polymerization of 500 or higher. Thus a pseudo-liquid-crystalline phenomenon can be allowed to occur in the stretched filaments during spinning, so that the resulting regenerated cellulosic fibers have improved resistance to fibrillation as well as improved dyeability and feeling.
    • 本发明的目的是克服原纤维化问题,这是在溶剂纺丝再生纤维素纤维中发现的缺点,从而提供高质量的再生纤维素纤维。 再生纤维素纤维是通过使用溶解在含有N-甲基吗啉N-氧化物的溶剂中的纤维素的纺丝原液在纺丝原液中所含的纤维素的平均聚合度保持在400以下且5以下的条件下制造的 将30%(重量)的纤维素调节至聚合度为500以上。 因此,在纺丝期间,拉伸长丝中可能会发生伪液晶现象,因此所得到的再生纤维素纤维具有改善的抗纤维化性能,以及改善的染色性和感觉性。
