Description

一种降低织带回缩率的低盐染色工艺
技术领域
本发明专利涉及一种染色工艺，具体涉及一种降低织带回缩率的低盐染色工艺。
背景技术
织带是以各种纱线和弹性芯线为原料制成狭幅状织物或管状织物，广泛用于服饰、鞋材、箱包、工业、农业、军需和交通运输等各产业领域中 ，在服装领域应用尤为广泛，随着社会的发展，织带的原材料由原先的棉线，纱线逐步发展到锦纶、维纶、涤纶、丙纶、氨纶、粘胶等，且编织方法及用途也发展到多元化。
织物内经纬纱的缩率是织物结构的重要参数之一,它关系到织物的许多物理机械性能、外观、织造工艺以及织物的分析和设计。纱线的不同染整工序对纱线的缩率有不同的影响。
活性染料由于色泽鲜艳、湿牢度优异、使用方便、适用性强等优点发展很快,然而传统活性染料染色需加入大量盐,如元明粉和食盐.电解质盐的应用,虽然减少了染料本身的污染,但对水源造成污染,使淡水盐化,破坏生态平衡,对水生物和土壤都有很大的危害,且污水中的可溶性盐的处理也较难。
发明内容
发明的目的：本发明的目的在于提供一种降低织带回缩率的低盐染色工艺，可以有效提升织带的染色性能，且织带的回缩率可以得到有效控制。
本发明采用的技术方案： 一种降低织带回缩率的低盐染色工艺，具体包括如下步骤：
a、 织带预处理：将织带送入蒸纱房进行蒸纱，控制蒸纱房温度以10℃/min的速率升至100℃，并保持该温度蒸纱10min，然后关掉蒸汽自然降温至常温，从蒸纱房取出织带自然晾干；
b、染料制备：在活性染料2%中投入促染剂40g/L和纯碱15g/L，控制浴比为10:1；
c、低盐染色：将步骤a晾干的织带投入步骤b制备的染料内，以1℃/min升温速度将染料温度升至80-90℃，并保温50min；
d、后处理：上色后的织带经过水洗固色后进行皂洗，然后送入定型烘干烫筒内，将织带在烫筒内卷绕3~5圈，控制烫干温度为90~100℃，使得织带表面水分刚好蒸发即可；
e、将织带从烫筒内取出形成成品，织带或缩率降至2~5%。
所述步骤d中固色温度为74-86℃，时间为13-28min。
所述纯碱组成为：碱金属磷酸盐：10-20%，碱金属氢氧化物：15-30%，碱金属碳酸盐：6-28%，有机烯酸：0.1-2%，有机膦酸1.6-16%，有机羧酸：0.01-5%，冠醚：0.01-2%，余量为水。
所述皂洗采用中性洗涤剂3g/L进行清洗，控制清洗温度为95℃以上，清洗时间2~6min。
所述促染剂为硫酸钠与氯化钾按照2:1混合而得。
有益效果：本发明所揭示的一种降低织带回缩率的低盐染色工艺，在染色前先用干蒸机对纱线进行干蒸，使纱线先进行充分的定型，并且能够充分提高纱线的缩率，在热定型烘干时，采用烫筒卷绕烫干形式，使得织带表面水分刚好蒸发即可，此时织带不会出现过度烘干而导致缩率增加的问题，这样做出的织带缩率能达到5-6%，满足客户的要求，也不会降低色穿度。
采用低盐染色工艺不仅可以实现对织带的有效染色，同时不会对环境造成影响。
具体实施方式
下面结合具体实施例对本发明的内容进行详细阐述：
