Description
技术领域
本发明属于纺织材料技术领域，具体涉及一种抗蛋白质污染的再生纤维素织物的制备方法。
背景技术
随着现代工艺技术的不断发展，对纺织品的功能性的要求也越来越高。众所周知，纺织品的吸附性好，与污渍、奶渍、油渍等物质接触后，就会难以清洗，因此抗蛋白质污染的纺织品也营运而成。
中国专利CN 104419998A公开的一种强效抗污纤维材料，将蓖麻油环氧乙烷缩合物和钛酸丁酯抗蛋白质污染剂加入到聚四氟乙烯和尼龙的原料中，经熔融纺丝制备得到具有强效抗污功效的纤维材料。中国专利CN202047291U公开的一种抗蛋白质污染皮革，将皮革包括纳米涂层、普通油处理层、PVC面层、PVC发泡层和基布，通过纳米材料提高皮革的抗蛋白质污染能力。中国专利CN 1710179A公开的一种纳米防污抗紫外涂层纺织品、服装及加工工艺，将纳米氧化钛、纳米氧化锌、纳米氧化硅制成纳米整理剂，对织物进行整理得到拒水拒油的防污纺织品或者服装。
由上述现有技术可知，目前针对纺织品的抗蛋白质污染整理多是针对油渍和污渍，对于蛋白质奶渍类的抗污整理并不多见，奶渍也属于日常生活中较为常见的污渍，奶渍属于蛋白质，其抗污整理不同于油渍和水渍，研究一种具有抗蛋白质污染的织物也具有一定的市场前景。
发明内容
本发明要解决的技术问题是提供一种抗蛋白质污染的再生纤维素织物的制备方法，本发明选用姜片和萝卜的植物有效成分结合枯草杆菌蛋白酶、纳米二氧化钛和聚乙二醇作为抗蛋白质污染整理剂，对活化的再生纤维素织物进行抗蛋白质污染整理，得到绿色环保的抗蛋白质污染再生纤维素织物。
为解决上述技术问题，本发明的技术方案是：
一种抗蛋白质污染的再生纤维素织物的制备方法，包括以下步骤：
(1)新鲜的姜片和萝卜清洗干净后，捣碎，加入氯化钠和去离子水中，加热煮沸，过滤得到植物提取液，再加入枯草杆菌蛋白酶、纳米二氧化钛和聚乙二醇，充分搅拌得到抗蛋白质污染整理剂；
(2)将再生纤维素织物置于乙醇溶液中，振荡清洗，取出，水洗烘干，经活化处理后得到预处理的再生纤维素织物；
(3)将步骤(2)制备的活化的再生纤维素织物先浸渍于没食子酸乙酯溶液中，取出，再浸渍于步骤(1)制备的抗蛋白质污染整理剂中，二浸二轧，取出，预烘，用乙醇水溶液清洗，烘干，得到抗蛋白质污染的再生纤维素织物。
作为上述技术方案的优选，所述步骤(1)中，姜片、萝卜和氯化钠的质量比为1:1-2：0.5-0.8。
作为上述技术方案的优选，所述步骤(1)中，加热煮沸的时间为2-3h。
