Description
技术领域
一种活性分散染料一浴涤棉混纺纱染色工艺,属于涤棉染色技术领域。
背景技术
涤棉混纺织物的染色,长期以来采用的是二浴法的染色工艺(包括染色前处理、分散染料染涤纶、还原清洗、水洗、活性染料套染棉和水洗步骤),即先在高温(130℃ )用分散染料染涤纶纤维,还原清洗后,再在常温(60℃以下)用活性染料染棉纤维。该传统工艺包括染色前处理、分散染料染涤纶、还原清洗、水洗、活性染料套染棉和水洗步骤,因为工序繁杂,加工耗时长(12h),造成生产效率较低。
二浴法工艺虽然能获得较好的染色效果,但因为工序繁杂,湿加工耗时长,水、电、汽消耗大,污水排放量大等问题,造成生产成本偏高。
现在多数厂家在用的一浴两步法工艺虽然工艺流程缩短,但在一浴中两种染料会互相影响,造成色光出现偏差,对样重演性差。
发明内容
本发明要解决的技术问题是:克服现有技术的不足,提供一种生产效率高、工艺流程短、色光偏差小的活性分散染料一浴涤棉混纺纱染色工艺。
本发明解决其技术问题所采用的技术方案是:该活性分散染料一浴涤棉混纺纱染色工艺,其特征在于,工艺步骤包括:前处理、一浴染色和后处理步骤;
所述的一浴染色步骤中同步进行分散染料染涤纶和活性染料套染棉,具体为:
1)染料配比:分散染料0.05%owf~0.28% owf,活性染料0.17% owf~0.3% owf;助剂:非离子高温匀染剂0.4 g/l ~0.6g/l,修补剂0.4 g/l ~0.6g/l,醋酸0.8 g/l ~1.3g/l,烷基酚聚氧烯醚磷酸酯1.8 g/l ~2.3g/l,硫酸钠37 g/l ~ 43g/l,碳酸钠13 g/l ~17 g/l;
2)染色过程:涤棉混纺纱进入染液后,先调整温度38℃~45℃,加入硫酸钠,运转9min ~ 11min;再加入活性染料和分散染料运转9 min ~11min,再加入剩余助剂运转9 min~11min,继续按0.95℃/min ~1.1℃/min的升温速率将温度提升至63℃~67℃,运转27 min~33min,再按0.95℃/min ~1.1℃/min的升温速率将温度升到128℃~133℃,运转37min~43min即完成染色。
本发明采用活性分散染料一浴的新工艺,在一浴中实现了两种纤维染色,去除了还原清洗及后处理步骤,生产效率大幅提高。且由于工艺流程缩短,能耗大幅降低。本发明主要对染料配方和染色工艺进行调整,消除一浴色光偏差。本发明的染料在助剂的作用下,具有良好溶解度、稳定物理状态、良好着色能力及高色牢度、可在近中性条件下固色以及在高温时基本不水解的优点,本发明工艺下,活性染料和分散染料在本配方中相互无影响,色光不会出现偏差,对样重演性强。
从染料配性、牢度性能、对染色条件的敏感性及成本等方面考虑,百斯特公司的活性染料及分散染料效果更佳。
优选的,所述染色过程:涤棉混纺纱进入染液后,先调整温度40℃~42℃,加入硫酸钠,运转10min;再加入活性染料和分散染料运转10min,再加入剩余助剂运转10min,继续按1℃ /min的升温速率将温度提升至65℃,运转30min,再按1℃ /min的升温速率将温度升到130℃,运转40min即完成染色。优选的染色条件下,染料的色牢度更高。
优选的,所述的非离子高温匀染剂为三苯乙烯苯酚聚氧乙烯醚和脂肪醇聚氧乙烯醚按质量比6~9:1的复配物。
优选的,所述的修补剂为苯甲酸二丁酯和月桂醇聚氧乙烯醚苯甲酸酯按质量比4~7:1的复配物。
本发明优选的非离子高温匀染剂和修补剂配方是本发明在高温条件下实现活性分散染料一浴的重要助剂;使用其他的非离子高温匀染剂或修补剂的效果不料想。
优选的,所述的后处理为:调节水洗溶液的水温至46℃~55℃,洗涤时间为12 min~18min;再向水洗溶液加碱性皂洗剂1.3g/l~1.7g/l后,将温度提升至93℃~94℃,运转17min ~25min,再将温度升至96℃~100℃洗涤17min~25min;再加入醋酸调节洗涤溶液pH至6.8~7.2,洗涤17 min ~25min。本发明提供的良好的后处理工序简单,节能减排,染色效率高,能更好的提高染色后的色牢度,放置在后处理过程中出现串色。
优选的,所述的碱性皂洗剂的加入量为1.5 g/l,碱性皂洗剂加入后将温度提升至95℃,运转20min,再将温度升至98℃洗涤20min。
优选的,所述的加入醋酸调节洗涤溶液pH至7,洗涤20min。
上述优选的后处理条件能更好地保证颜色色光纯正。
与现有技术相比,本发明的一种活性分散染料一浴涤棉混纺纱染色工艺所具有的有益效果是:1、本发明工艺采用一浴一步法,生产时间仅耗时8h,较原工艺缩短7h,生产效率大幅提高,同比两浴两步工艺,一浴两步工艺,能有效提高产量。
2、本发明工艺由于生产时间缩短,水、电、蒸汽消耗也相应减少,降低了生产成本。主要是减少了中间的升温,降温过程,及还原清洗。
3、本发明工艺生产颜色色光纯正,符样率高,对样难度降低,本工艺采用染化料比其它有更佳的稳定性,所做的多项测试确保了两种染料有更好的相容性。
