Description

一种棉织物漂白染色工艺
技术领域
本发明属于纺织品印染技术领域，具体涉及一种棉织物漂白染色工艺。
背景技术
棉织物又称棉布，是以棉纱为原料织造的织物。棉织物以优良的服用性能成为最常用的面料之一，广泛用于服装面料、装饰织物和产业用织物。随着纺织印染加工的深入发展，棉织物品种日益丰富，外观和性能及档次也不断提高。但棉织物易褪色，色牢度不高，荧光染色效率也不高，且易发霉变质，此外，由于棉纤维是电的不良导体，容易发生静电、粘毛、起球等问题。
发明内容
针对现有技术的不足之处，本发明的目的在于提供一种棉织物漂白染色工艺。
本发明的技术方案概述如下：
一种棉织物漂白染色工艺，包括以下步骤：
S1：预处理：将全棉面料浸入预处理液中，控制浴比为1：(5-10)，40-55℃浸渍处理0.5-1.5h，脱液、烘干后，得预处理后全棉面料；
所述预处理液包括以下质量百分比原料：三乙醇胺5-10％、脂肪醇聚氧乙烯醚硫酸钠2-3％、十四烷基二甲基苄基氯化铵1-1.5％、去离子水补足余量；
S2：精练漂白：将棉针织物加入精练漂白液中，控制浴比为1：(12-16)，升温至45-55℃，再保温处理30-50min，再升温至95-105℃，继续搅拌30-50min，冷却、脱液、烘干后，得漂白后棉针织物；
所述精练漂白液包括以下质量份原料：50wt％双氧水8-12份、次氯酸钠5-10份、偏硅酸钠1-3份、精练剂3-6份、精练酶0.5-2份、氢氧化钠5-8份、茶皂素2-3份、乙二胺四乙酸二钠2-3份、稀土盐助剂1-2份、去离子水100份；
S3：染色处理：将漂白后棉针织物置于荧光染色液中，控制浴比为1：(10-15)，调节pH至4.5-5.5，40-50℃预热处理0.5-1h，再以1-5℃/min的速率升温至95-105℃，保温染色处理1-1.5h后，进行水洗、固色、干燥，得染色后棉织物；
所述荧光染色液包括以下质量百分比原料：酸性荧光染料1-2％、聚氧乙烯脂肪醇醚0.5-1％、琥珀酸烷基酯磺酸钠0.5-1％、柠檬酸3-5％、去离子水补足余量；
S4：柔软处理：将染色后棉织物干燥后，再其表面均匀涂覆柔软剂，涂覆量为60-100g/m2，100-110℃热处理0.5-1h，自然冷却后即可。
优选的是，所述精练剂由以下质量百分比原料组成：脂肪酸甲酯乙氧基化物10-20％、脂肪醇聚氧乙烯醚5-10％、异辛醇聚氧乙烯醚磷酸酯10-20％、十二烷基磺酸钠4-8％、乙二醇单丁醚5-10％、消泡剂2-4％、三乙烯四胺六乙酸3-5％、去离子水补足余量。
优选的是，所述精练酶包括以下质量份原料：碱性纤维素酶10-15份、碱性果胶酶3-5份、碱性蛋白酶5-10份、木聚糖酶4-8份、漆酶3-5份。
优选的是，所述稀土盐助剂包括硝酸镧、醋酸镧、氯化镧、硝酸铈、醋酸铈、氯化铈、醋酸铕、氯化铕、硝酸铕、硫酸铕、醋酸镝、氯化镝、硝酸镝、硫酸镝中的一种或多种。
优选的是，所述固色的具体操作方法为：将水洗后棉针织物置于0.5-2wt％固色剂水溶液中，控制浴比为1：(5-10)，45-55℃浸渍处理1h，排液后，再于100-120℃汽蒸处理15-30min。
优选的是，所述固色剂包括氯化十六烷基吡啶、溴化十六烷基吡啶、胺醛树脂型双氰胺甲醛初缩体中的一种或多种。
优选的是，所述酸性荧光染料包括酸性玫瑰红B、偶氮荧光桃红中的一种或两种。
优选的是，所述柔软剂包括以下质量份原料：聚醚环氧硅油20-30份、有机硅季铵盐抗菌剂2-3份、二环氧三甘醇缩水甘油醚2-3份、乙酰丙酮铬0.5-1份、丝素蛋白5-10份、聚吡咯3-5份、聚乙二醇3-5份、去离子水10-15份。本发明的有益效果：
