Description

纤维素纤维织物湿法转移印花用浸轧液及其配制方法
技术领域
本发明属于纺织品印花技术领域,具体涉及一种纤维素纤维织物湿法转移印花用浸轧液及其配制方法。
背景技术
织物的转移印花工艺分为干法转移印花和湿法转移印花两种。干法转移印花即热转印,主要用于涤纶织物的转移印花;湿法转移印花前几年被称为冷转印,主要因为该项技术在研究初期是针对棉织物的转移印花,且采用冷堆固色工艺,为了与热转印相区别,且凸显其在节能减排方面的优势,故也称为冷转印。
采用冷堆固色固然有如下的优点:①节约能源;②染料利用率高,得色鲜艳;③染料可向纤维内部渗透,花型不易露白;④糊料始终处于润湿状态,易于水洗。但是该工艺在生产过程中存在的一些问题,也不容忽视,主要包括:①打样效率低,颜色不易把控;②精细线条花型在冷堆过程中易出现花型的渗化;③针对薄型织物,由于染料的直接性不同,冷堆过程中染料迁移到纤维内部及反面的量不同,从而导致色差及匹差增大。
现有技术通过采用蒸化固色工艺替代冷堆固色,同时配合适合蒸化工艺的染料和浸轧液,能够较好的解决上述问题。但是仍然存在湿法转移印花后的纤维素纤维织物得色率低、牢度不高(只有3-4级)的问题。
发明内容
本发明的目的在于针对现有技术的不足,提供一种能够提高湿法转移印花后织物得色率和牢度的纤维素纤维织物湿法转移印花用浸轧液及其配制方法。
实现本发明目的的技术方案是:一种纤维素纤维织物湿法转移印花用浸轧液,由下述重量百分比的组分配制而成:2%~5%的碳酸氢钠、0.1%~2%的碳酸钠、0.5%~2%的间硝基苯磺酸钠、5%~15%的尿素、0.5%~2%的螯合分散剂、1%~3%的防泳移剂、0.5%~2%糊料以及余量的水。
上述螯合分散剂为对铁、铜、镁、钙等离子有螯合分散作用的阴离子表面活性剂。
上述防泳移剂为对活性染料烘干时泳移有防止作用的阴离子表面活性剂。
上述糊料为改性淀粉、瓜儿豆胶、海藻酸钠、龙胶或者羧甲基纤维素钠。
上述糊料的粘度优选为400±20mPa·s(1%)。
上述纤维素纤维织物湿法转移印花用浸轧液的配制方法,具有以下步骤:
①按照配方依次称取水、碳酸氢钠、碳酸钠、间硝基苯磺酸钠、尿素、螯合分散剂、防泳移剂以及糊料待用;
②先将碳酸氢钠和碳酸钠依次加入到水中,边加边搅拌至完全溶解;然后加入间硝基苯磺酸钠,边加边搅拌至完全溶解;接着加入尿素,边加边搅拌至完全溶解;再接着依次加入螯合分散剂和防泳移剂,边加边搅拌至完全溶解;最后缓慢加入糊料,边加边快速搅拌至完全溶解;
③用200目滤网过滤步骤②得到的溶液,即得浸轧液。
本发明具有的积极效果:采用本发明的浸轧液进行纤维素纤维织物湿法转移印花,不仅能够使得织物颜色饱和丰满、均匀,得色率高,花型精细度高,而且水洗牢度可达4级以上。
