Abstract
本发明公开了一种棉织物的印染前处理工艺，包括原布准备、烧毛、退浆、煮练、漂白、丝光，其中，退浆和煮练采用生物酶结合氢氧化钠的方式进行。本发明所公开的棉织物的印染前处理工艺处理效果好，安全环保。
Description
技术领域
本发明涉及一种印染前处理工艺，特别是一种棉织物的印染前处理工艺。
背景技术
棉织物的经纱，在织造前大都先经过浆纱，以提高经纱的强度、耐磨性和光滑程度。而浆料在染整过程中会影响织物的润湿性，并阻碍化学品对纤维接触，因此织物染整前一般都先经退浆处理。而棉纤维伴生物、棉籽壳以及退浆后残余浆料则必须通过煮练除去，以使织物获得良好的润湿性及外观。
对棉织物的退浆和煮练，通常采用碱处理，但该种处理方式会产生大量的碱性废水，对环境造成不良影响；目前市场上新兴的生物酶法具有反应迅速、环保有效地优点，但同时生物酶具有强烈的专一性，无法有效地去除棉织物中所有需要去除的成分。
发明内容
本发明的目的在于克服现有技术中存在的缺陷，提供了一种棉织物的印染前处理工艺，包括原布准备、烧毛、退浆、煮练、漂白、丝光；其中，退浆和煮练采用生物酶结合氢氧化钠的方式进行，具体步骤为：
1）退浆处理：采用淀粉酶浸渍法，浴比为1：20，加入浓度为3-5g/L的淀粉酶，0.5-2g/L的渗透剂JFC，调整pH为6-7，温度为60-70℃，浸渍时间为30-60min，然后进行水洗，时间为5min；
2）煮练处理：采用纤维素酶浸渍法，浴比为1-30，加入浓度为10-15g/L的纤维素酶，0.5-2g/L的非离子表面活性剂，调整pH为5-6，温度为50-60℃，浸渍时间为45-90min，然后进行水洗，时间为10min；
3）进一步处理：采用绳状汽蒸法，加入浓度为15-20g/L的氢氧化钠，1-2g/L的过硫酸钾，1-2g/L的渗透剂JFC，0.3-0.5g/L的表面活性剂，轧余率为110%，温度设为100℃，处理时间为15min。
本发明的优点和有益效果在于：先采用淀粉酶和纤维素酶处理，可将棉织物中的大部分浆料和纤维素进行分解去除，一方面降低了烧碱的处理负荷，可减少后续烧碱处理时的用量，减少污水量，降低对环境的影响；另一方面，生物酶将许多大分子物质分解成了小分子物质，提高了碱液的渗透率和降解速度，进而降低了处理时间，同时提高了处理效果，处理后的棉织物外观和手感更佳，具有更高的经济价值。

2）煮练处理：采用纤维素酶浸渍法，浴比为1-30，加入浓度为10-15g/L的纤维素酶，0.5-2g/L的非离子表面活性剂，调整pH为5-6，温度为50-60℃，浸渍时间为60min，然后进行水洗，时间为10min；
3）进一步处理：采用绳状汽蒸法，加入浓度为15-20g/L的氢氧化钠，1-2g/L的过硫酸钾，1-2g/L的渗透剂JFC，0.3-0.5g/L的表面活性剂，轧余率为110%，温度设为100℃，处理时间为15min。
