Description
技术领域
本发明涉及毛条染色技术领域，特别涉及一种提高天丝纤维可梳理性的染色方法。
背景技术
天丝纤维由于具有天然纤维的吸湿性，涤纶纤维的干湿高强力，粘胶纤维的悬垂性及真丝纤维的手感，因而具有良好的使用性能。但天丝纤维也有明显的弱点，由于天丝纤维原纤间结合较弱且没有弹性，如受机械摩擦，天丝纤维外层会发生断裂，形成毛茸，特别在湿态情况下，更易产生，严重时还会缠结成棉粒，给染色及梳理带来了较大的困难。
基于上述情况，本发明提出了一种提高天丝纤维可梳理性的染色方法。旨在有效地降低天丝纤维染色过程中的纠缠毡化，在复洗烘干时利用低张力的牵引系统，减少断头问题，提高成球性能，为有效梳理提供坚实的基础。
发明内容
本发明为了弥补现有技术的缺陷，提供了一种简单高效的提高天丝纤维可梳理性的染色方法。
本发明是通过如下技术方案实现的：
一种提高天丝纤维可梳理性的染色方法，其特征在于：包括低密度装球，低损伤染色和低张力的复洗烘干，其中：
（1）低密度装球即降低天丝球的装缸密度，降低压球机压力，使染笼的装缸密度由0.35g/cm³降低为0.28g/cm³，从而实现低穿透力柔性染色，最大限度的减少天丝纤维毡化和原纤化；
（2）低损伤染色过程采用染色、固色一浴法和从外向内的循环方式，染色泵速由75%降低为55%，以减轻染液的穿透力，缩短染色时间，减少染色过程对天丝纤维的损伤；低损伤染色步骤如下：
按浴比1:10计算，副缸进水将按配方比例的硫酸钠加入副缸搅拌均匀，加入主缸运转10min；料缸1将配方比例的染料和渗透剂SP-2溶解加入主缸运转10min，使染液均匀穿透被染天丝球；然后，以0.8℃/min的速率升温至50℃运转5min，使染液各组分均匀稳定的向天丝纤维内部渗透，再以1℃/min的速率升温至80℃运转20min，以使染料充分渗透至天丝纤维内部；从料缸2加入碳酸钠调整染液pH至9~9.5，继续80℃保温40min，以使染料分子充分与天丝纤维发生反应固色；固色完毕后降温排水并溢流冲洗，再用热水60℃冲洗10min，使剩余染料冲洗干净确保牢度要求；最后，加入抗静电剂和柔软剂在50℃运转10min，以提高天丝纤维的抗静电性能和可梳理性；
（3）低张力的复洗烘干是指在复洗机的压辊之间增加传送带，天丝纤维铺在传送带上面，通过传送带的辅助作用来减少生产过程中的张力，以减少断头的产生。
所述低损伤染色过程中染液的各原料及重量配比为：
染料：1~10份，硫酸钠：60~80份，渗透剂SP-2：0.5~1份，水：1000份。
为了提高其均匀程度，避免复洗加料不匀的现象，所述述低损伤染色过程后处理中加入1% o.w.f的抗静电剂FN 1027和0.5% o.w.f的柔软剂GA处理，以提升其在后道复洗以及梳理过程中的抗缠绕和可梳理性能。
本发明的有益效果是：该提高天丝纤维可梳理性的染色方法，能够有效降低染色对天丝纤维的损伤及天丝纤维间的纠缠毡化，降低天丝纤维的断头，减少梳理难度，对于天丝混纺产品的开发及使用具有非常好的推广使用价值。
