Description

一种前处理与染色一浴的织物染色工艺
技术领域
本发明属于纺织印染技术领域,具体涉及一种前处理与染色一浴的织物染色工艺。
背景技术
涤纶纤维是由聚对苯二甲酸乙二酯制成的疏水性纤维,由于涤纶分子链结构紧密,缺乏羧基、磺基等亲水性基团而不能用直接染料、酸性染料、碱性染料等染色,现有的染色方法大都采用高温高压、热熔或载体存在条件下用分散染料染色,但在高温高压染色中,一些分散染料耐高温分散稳定性差,导致染色不均匀的问题经常出现,同时由于在高温高压条件下设备安全性的限制,染色批量小、浴比大、劳动强度高、各项消耗大的问题非常明显,且生产工艺流程长、各项能源消耗大,排污严重、生产效率低下,这就与生态染色的发展趋势严重背离,提高上染百分率,但载体易残留在织物或者纤维上,影响偶氮分散染料的日晒牢度,同时使用时会污染环境和毒害人体,且也存在容易褪色的问题,影响织物的服用性能,有待进一步改进。
发明内容
本发明的目的是克服现有技术的缺点,提供一种工艺流程短、染色均匀、色牢度高的涤纶的染色工艺。
本发明采用如下技术方案:
一种前处理与染色一浴的织物染色工艺,包括如下步骤:
(1)、前处理与染色一浴:进布,加水,加0.5-1.5g/L的冰醋酸、0.5-0.8g/L的分散剂、0.5-0.8g/L的渗透剂,以2.5-3.5℃/min升温至75-85℃,加入0.5-1.5g/L的高温匀染剂,保温反应15-25min,加入染料,接着以1-2℃/min升温至105-115℃,加入1-2g/L的烧碱、2-3g/L的双氧水,保温反应5-15min,然后以1.5-2.5℃/min升温至130-140℃,保温反应35-45min,最后以2.5-3.5℃/min降温至65-75℃,排液;
(2)、后处理:加水,加入0.2-0.6g/L的碱性还原清洗剂、0.8-1.2g/L的冰醋酸,以2.5-3.5℃/min升温至75-85℃,清洗15-25min,排液,重新加水,并加入0.3-0.8g/L的液蜡,处理10-20min;
所述高温匀染剂包括以下重量份的原料:十二烷基苯磺酸钠20-25份、单硬脂酸甘油酯7-12份、对苯二甲酸二甲酯15-20份、二羧基聚醚8-12份、乙撑双硬脂酰胺5-8份、甘油醚油酸酯12-15份、对甲苯磺酸9-12份、异丁基三乙氧基硅烷25-30份、水420-480份。
进一步的,所述前处理与染色的浴比为1:4.5-5.5。
进一步的,所述染料包括0.6%的朱红NR染料、1.1%的H4GFS大红染料和0.28%的S-5BL红玉染料。
进一步的,所述碱性还原清洗剂为碱性还原清洗剂DR-84CN。
进一步的,所述分散剂为分散剂P-19。
进一步的,所述渗透剂为渗透剂JFC。
由上述对本发明的描述可知,与现有技术相比,本发明的有益效果是:本发明将前处理与染色合并,采用同一浴比,缩短了工艺流程,减少了资源的浪费,并且加入的高温匀染剂,组分简单、原料成本低、对环境友好,无污染,符合生态染色的发展趋势,且该高温匀染剂的各成分之间能相互协调作用,使高温匀染剂体现出较好的缓染性、移染性和分散性,保证涤纶染色均匀、提高染色的色牢度;在前处理与染色这个步骤中,通过加入分散剂、高温匀染剂和渗透剂,通过三者之间的相互配合,使染色后的织物不会出现色条、色斑等疵点现象,加入的高温匀染剂,能够高温条件,具有较好的缓染性、移染性和分散性,与分散剂和渗透剂配合使用,保证制得的织物,染色均匀,色牢度高。
