技术领域
本发明涉及纺织品染整领域，特别是一种酸性阳离子交换纤维的染色方法。
背景技术
离子交换纤维是一种纤维状离子交换材料，当离子交换纤维跟电解质溶液接触时，纤维上的离子能跟溶液里的离子作有选择性的交换。它分阳离子交换纤维、阴离子交换纤维和两性离子交换纤维。离子交换纤维可用于吸附重金属及色素，其作为新性功能高分子材料，具有独特的化学及物理吸附和分离性能，在一些相关领域有着不可替代的作用。
随着新型阳离子改性纤维的推广和应用，其面料不仅光泽性、透气性、吸水性好，还有个特性是低温可染色性能。一般情况下，阳离子交换纤维的染色采用二浴法来染色。二浴法染色工艺主要存在的问题是：工艺流程长、染色时间长、耗水、耗能、排污量大，且容易损伤产品，产品起毛起球、颜色不稳定。
发明内容

（2）配制染料：将染料原料加入水中搅拌均匀，所述染料包括以下重量份数的组分：30-40份聚酰胺树脂、15-30份苯并蒽酮、15-20份吖啶稠环烃、10-20份有机羧酸化合物、10-15份聚醚改性硅氧烷、5-10份脂肪醇聚氧乙烯醚、12-36份光稳定剂和5-15份抗氧剂；
（3）染色：将含有酸性阳离子交换纤维放入染缸，进水到规定水量，升温到30±5℃时加入吸水速干剂、分散匀染剂和冰醋酸，转2-5min后加入分散染料，继续转3-8min后加入沉淀防止剂，继续转2-5min后加入染料，继续转3-8min后以1-1.5℃/min升温到80±2 ℃，保温8-12min后再以0.5-1℃/min升温到100±2℃，接着再以1.5-2℃/min升温到130 ±2℃，保温55±5min后降温到80℃以下排水；
（4）后处理：对染色后的酸性阳离子交换纤维进行热水洗，皂洗，水洗，柔软处理。
优选的是，步骤（1）中所述有机醇为乙二醇、三甘醇、丙三醇中的一种。
