Description

一种涤纶面料的染色处理方法
技术领域
本发明属于面料加工处理技术领域，具体涉及一种涤纶面料的染色处理方法。
背景技术
涤纶是合成纤维中的一个重要品种，是我国聚酯纤维的商品名称。是以精对苯二甲酸（PTA）或对苯二甲酸二甲酯（DMT）和乙二醇（MEG）为原料经酯化或酯交换和缩聚反应而制得的成纤高聚物——聚对苯二甲酸乙二醇酯（PET），经纺丝和后处理制成的纤维。涤纶是一种常用的纺织面料，在实际使用时需要进行染色处理，但现有的染色处理方法较为简单，步骤搭配不合理，导致面料的使用特性较差，不稳定，需要进一步的改进。
发明内容
本发明的目的是针对现有的问题，提供了一种涤纶面料的染色处理方法。
本发明是通过以下技术方案实现的：
一种涤纶面料的染色处理方法，包括如下步骤：
（1）辐照处理：
将涤纶面料放入到紫外线辐照箱内进行辐照处理，1~1.5h后取出备用；
（2）染色剂制备：
a.按对应重量份称取下列物质备用：7~9份甲基丙烯酸甲酯、2~4份硬脂酸盐、1~3份丙三醇、1~2份聚乙烯醇、0.5~1.5份过硫酸钙、1~3份醋酸乙酯、0.2~0.5份壬基酚聚氧乙烯醚、0.5~1份石蜡、5~7份染料、100~110份去离子水；
b. 将操作a称取的所有物质共同投入到搅拌罐内，超声处理1~2h后取出得染色剂备用；
（3）染色处理：
将步骤（1）处理后的涤纶面料放入到步骤（2）所得的染色剂内，然后加热保持染色剂的温度为50~55℃，不断搅拌处理1~1.5h后将涤纶面料取出烘干即可。
进一步的，步骤（1）中所述的辐照处理控制紫外线辐照箱内的功率为550~600W，紫外线的波长为270~300nm。
进一步的，步骤（2）操作a中所述的硬脂酸盐为硬脂酸钠、硬脂酸镁、硬脂酸锌中的任意一种。
进一步的，步骤（2）操作b中所述的超声处理时控制超声波的频率为400~450kHz。
本发明相比现有技术具有以下优点：
本发明优化改善了染色处理的方法，其中先对涤纶面料进行了辐照处理，提升了涤纶面料的表面活性，之后又配制了一种专用的染色剂，其对涤纶面料的亲和性高，共同处理后的涤纶面料的皂洗牢度为5~6级，染色剂结合牢固，K/S值为9.3~9.5，染色性能良好，极具市场竞争力和推广使用价值。
