摘 要:采用有色涤纶长丝与天然纯棉纤维为原料,制备出一种具有间隔色彩效果的新型复合纱线。为探讨该复合纱线的工艺优化方案,研究了涤纶长丝预加张力、捻系数、后区牵伸倍数(E后)、涤纶长丝含量等工艺参数对纱线的性能影响。结果表明,有色涤纶长丝张力为15 cN、捻系数为380、后区牵伸倍数为1.5、涤纶长丝含量为20%时,纱线的综合性能较佳,且纱线色彩丰富、具有独特的立体视觉效果。该纺纱方法科学地实现了纤维间色彩的调配,达到物理配色的目的,对提高色纱产品品质、促进色纱的实际生产应用等具有指导意义。

Abstract:A new-type of interal color composite yarns was manufactured with colored polyester filament and 100% natural cotton fiber. In order to explore the process optimization of the composite yarns, the effect of process parameters such as pre-tension of polyester filament, twist coefficient, draft multiple in back zone (Eback), and the content of polyester filament on yarn properties were studied. The results show that the optimal overall performance can be achieved if the tension of colored polyester filament is 15 cN, twist coefficient is 380, draft multiple in back zone is 1.5, and the content of polyester filament is 20%. With such parameters, the composite yarns are colorful and have a unique three-dimensional visual effect. The spinning method has scientifically realized color matching of fibers and attained the purpose of physical color matching, which is of guiding significance to improving the quality of colored yarn products and promoting the real production and application of colored yarns.

Key words:spinning process parameters; physical color matching; interal color; colored polyester filament ; composite yarns

随着经济的快速发展,人们对纺织品的多样性、时尚化的要求日益提高,色纺纱在纺织品中的运用也逐步广泛,市场发展前景广阔[1-2]。传统色纺纱通常是将纤维先进行染色,再将两种或两种以上不同颜色的纤维混合,纺制成具有独特混色效果的纱线。在染色过程中,本色纤维需经受酸、碱、高温等作用,在获得色彩的同时,纤维中的蜡质、脂、胶等物质被去除或減少,导致染色之后纤维的聚合度下降、强力损失、可纺性下降[3-5]。且纤维染色环节中使用到的染料、助剂等种类繁杂,导致废水中的污染物成分复杂,酸碱性波动大,相较于其他行业废水水量大,处理难度高,环境污染大[6]。……
