摘　　要：分析了合纤长丝类织物在绳状染色过程中产生折痕的原因,并提出解决方法。合纤长丝在纺丝过程中受到多次牵伸,存在很大残余内应力。在染整过程中,合纤长丝第一次遇热、遇湿会发生强烈收缩;当织物纵向受力不均匀时,纤维经纬分子链段发生剧烈运动,从而产生较大差异。染色后的织物表面对光的反射方向不一致,产生犹如“鸡爪印”的表观现象。在间歇式绳状湿加工(如前处理、染色)过程中,对张力和温度进行控制,使织物纤维能够均匀收缩,可有效避免这种折痕的产生。In this paper, the causes of crease formation in rope dyeing process of the synthetic filament fabrics are analyzed, and a solution is proposed. The synthetic filaments are subjected to multiple drawings during the spinning process, and there is a large residual internal stress. In dyeing and finishing process, the synthetic filaments are heated and wet at the first time, they will shrink strongly; when the fabric in the longitudinal direction is uneven, the fiber latitude and longitude molecular segments undergo vigorous movement, resulting in large differences. The surface of the dyed fabric is inconsistent in the direction of light reflection, resulting in an apparent phenomenon like a "chicken paw print". In the intermittent rope wet processing(such as pre-treatment, dyeing), the tension and temperature are controlled to make the fabric shrink evenly, which can effectively avoid such creases.
