Description
技术领域
本发明涉及一种纺织品的染整工艺,具体涉及一种锦棉面料短流程染整工艺,属于面料的染整领域。
背景技术
锦纶具有耐磨、耐用、强度高、弹性好、比重小等特点,且具有一定的吸湿性,而棉织物具有柔软舒适透气等优良特性,因而锦棉织物既保持良好的透气和舒适性,又具有很好的高强及耐磨性,受到消费者的欢迎。
锦棉面料传统染整流程加工时,前处理多采用多浴多步法,即分别进行退浆、精练、漂白,染色则通常采用二浴法,先染棉再染锦纶,工艺流程长、耗时、耗能。
将传统染整工艺前处理工艺缩短,采用一浴法前处理,并同浴染棉及锦纶,则可显著缩短整个染整工艺。

锦棉面料短流程前处理工艺中,可以采用适于一浴法的复合助剂。
一种锦棉面料一浴法前处理剂,由螯合分散剂、仲烷基磺酸钠SAS60、XP-70、AEO-9、APG、水组成,以质量份计,螯合分散剂21-32份、仲烷基磺酸钠SAS6026-38份、XP-7014-19份、AEO-99-15份、APG11-17份、水560-680份;所述的螯合分散剂由马来酸酐混合双酯(如式1所示)、马来酸单酯化物(如式2所示)、丙烯酸、马来酸酐、引发剂、氢氧化钠、二硫化碳、水等聚合而成;聚合时,先将14份马来酸酐混合双酯、16份马来酸单酯化物、20份丙烯酸、6份马来酸酐及400份水置于反应釜中,搅拌溶解,通氮气30min,升温至70℃,加入0.7份引发剂,保温反应6h,然后降温至20℃以下,按[n(马来酸酐混合双酯)+n(马来酸单酯化物)]:n(NaOH):n(CS2)=1:4:3先加入NaOH,再缓慢滴加CS2,于25℃反应3h,再于45℃反应2h,得所述螯合分散剂;螯合分散剂分子结构如上述式3所示。
将560-680份水置于搅拌釜中,分别加入螯合分散剂、仲烷基磺酸钠SAS60、XP-70、AEO-9、APG,搅拌均匀后,过滤即可得锦棉面料一浴法前处理剂。
本发明锦棉面料短流程染整工艺,以螯合分散剂与常规助剂、碱及氧等化学品复配成前处理剂,将锦棉面料的退浆、精练、漂白传统前处理工艺缩成一步一浴法,缩短了前处理的工艺流程。
此外,还采用活性染料染棉、弱酸性染料染锦的一浴法染色工艺,缩短了染整工艺流程,节约了能源、资源,提高了生产效率。
锦、棉纤维染色后,为保证染色品的色牢度,通常会在染色后以清水浴加入专门的锦纶、棉用固色剂进行固色处理。若染色后不专门固色处理,而是在定型时,直接将固色剂同硅油柔软剂拼混,则容易出现助剂破乳、分层现象,易在面料表面形成难以去除的污垢、硅油斑。本发明短流程染整工艺,采用的硅油乳液,含硅大分子链中含有较高比例的阳离子电荷,以该阳离子硅油乳液对染色后的锦棉面料进行后整理,阳离子基团对活性染料、酸性染料起到固色作用,-Si-OCH3基团、环氧基团与锦纶的胺基、棉中的羟基反应,增强了硅油与面料的结合牢度,使锦棉面料具有柔软手感的同时还提高了面料的色牢度及抗菌性能,将固色、柔软整理同浴处理,缩短了流程。
