Description

涤粘混纺仿毛嵌腈纶织物的碱减量工艺
技术领域
本发明涉及一种织物碱减量工艺，特别涉及一种涤粘混纺织物的碱减量工艺。
背景技术
涤粘混纺织物兼具涤纶织物和粘胶织物的特点，强度高、弹性好、耐摩擦、吸湿性好。涤粘混纺织物经仿毛处理后，光泽柔和、回弹性好，具有精纺全毛织物的优点。腈纶纤维的耐光和抗辐射性能优越，耐酸及耐候性好，素有“合成羊毛”之称。常规涤粘混纺仿毛织物的碱减量处理大多选择在高温高压溢流缸内进行，一般有如下两种工艺：1、以水量计，加入40 g/L的36°Bé的氢氧化钠溶液，浴比采用1:10，在100℃下保温60min后水洗干净；2、以水量计，加入20 g/L的36°Bé的氢氧化钠溶液，浴比采用1:10，在120℃下保温30min后水洗干净。
上述两种工艺存在液碱用量大、减量温度高等问题。当涤粘混纺仿毛织物中嵌入腈纶条/格后，采用常规工艺进行碱减量处理时，腈纶条/格会严重泛黄且失去弹性，成品熨烫后起皱或气泡，严重影响服用性能。经分析，主要是因为腈纶纤维耐碱性和耐高温性较差，在强碱和高温湿热条件下水解易泛黄变硬，导致熨烫后与布面收缩不一致引起起皱或气泡。目前，还没有专门针对涤粘混纺仿毛嵌腈纶织物的合适的碱减量工艺，能够使得处理后的织物既达到手感要求，又不泛黄且弹性好，成品熨烫后平整并具有较高的服用性能。
发明内容
本发明的目的在于克服现有技术的不足，提供一种能使织物既达到手感要求，又不泛黄且弹性好，成品熨烫后平整并具有较高服用性能的涤粘混纺仿毛嵌腈纶织物的碱减量工艺。
为了达到上述目的，本发明的涤粘混纺仿毛嵌腈纶织物的碱减量工艺，包括如下步骤：
1、配制碱液：将36°Bé的氢氧化钠溶液、低温减量促进剂加入水中配制成碱液；以水量计，氢氧化钠溶液的加入量为5-15g/L，低温减量促进剂的加入量为3-5g/L；其中低温减量促进剂由水、平平加、十二叔胺和氯化苄组成；
2、碱减量处理：将涤粘混纺仿毛嵌腈纶织物投入上述配制的碱液中，碱减量浴比为1:8-12，然后升温至90-100℃，保温90-100min后水洗干净。
作为优选，步骤1中所述氢氧化钠溶液的加入量为10g/L，低温减量促进剂的加入量为4g/L。
作为优选，步骤1中所述低温减量促进剂由如下方法制备得到：在反应釜中搅拌溶解1047.5kg的水和2-5kg的平平加，然后加入100kg的十二叔胺，再滴加50kg的氯化苄，自动升温至 90℃保温 30 分钟后出料。
本发明的涤粘混纺仿毛嵌腈纶织物的碱减量工艺中氢氧化钠的用量为常规工艺的1/4-1/2，通过减少氢氧化钠用量和使用低温减量促进剂,使得织物中的腈纶纤维能够在较弱的碱性条件和较低的温度条件下水解，同时保证仿毛处理后的涤粘混纺纤维也能减量充分和均匀,能够使得处理后的织物既达到手感要求，又不泛黄且弹性好，成品熨烫后平整并具有较高的服用性能。
