Abstract
本发明公开了一种非浸泡抗菌防臭棉的制备工艺。所述非浸泡抗菌防臭棉制备工艺包括以下步骤：对干燥的棉纤维进行预处理；对预处理后的棉纤维进行抗菌处理，制得抗菌棉纤维；对聚氨酯纤进行抗菌处理，制得抗菌聚氨酯纤维；将制得的抗菌棉纤维、抗菌聚酰胺纤维与亚麻纤维、聚乳酸纤维混纺并卷，制得抗菌防臭棉。本发明所述的抗菌防臭棉制备工艺中将普通棉纤维进行抗菌处理，与抗菌聚酰胺纤维混纺达到抑菌灭菌效果，避免臭味的产生。制备的抗菌防臭棉抗菌性能、耐水洗性能优异，且不会不会破坏皮肤自然平衡。
Description
技术领域
本发明涉及织物处理技术领域，具体涉及一种非浸泡抗菌防臭棉的制备工艺。
背景技术
人们在日常生活中会不可避免接触到各种各样的细菌、霉菌、病毒等微生物，普通的棉质纺织品由于不具备抗菌性能，在人们日常穿着过程中，残留的人体分泌物为微生物提供了良好的生存环境，特别是在高温潮湿、通风较差的环境中细菌和霉菌会大量滋生和繁殖，使得棉织物发臭、发霉变色，甚至严重影响人类生命健康，因此人们对棉织物的改性和抗菌功能化的需求越来越旺盛，要求也越来越高。
制备抗菌性的棉织物原理和方法不尽相同，目前棉织物抗菌功能化主要通过抗菌整理剂对棉织物整理从而获得抗菌性，具体常采用浸轧、喷涂、浸渍等工艺对织物进行抗菌整理。整理剂与纺织品之间主要依靠物理吸附结合，一般不依靠化学键连接，因而织造的棉织物耐水洗牢度差，抗菌功能性不持久，随着洗涤次数增加，棉织物的抗菌效果会逐渐消失。常用的抗菌整理剂为纳米银离子抗菌剂，纳米银离子抗菌剂是一种溶出型抗菌整理剂，在抗菌过程中会杀死人体皮肤表面的有益菌群，破坏皮肤自然平衡，增加细菌侵害感染几率。
针对采用纳米银抗菌整理剂获得抗菌性的棉织物出现的耐水洗牢度差、抗菌效果递减的问题，中国专利(CN 106192395 B)公开了一种改性棉织物表面增强纳米银抗菌棉织物耐水性性能的方法。方法具体包括以下步骤：步骤一：将棉织物浸渍到0.5-5mol/L的半胱氨酸盐酸盐溶液中，然后置于烘箱中160-180℃加热5min，使半胱氨酸羧基与纤维素羟基发生酯化反应从而将其键接到棉织物表面，取出棉布，清洗三次，置于烘箱中在60-80℃的温度下烘干，得到改性棉织物；步骤二：将0.001-0.01mol/L柠檬酸钠溶液一次性倒入0.005-0.05mol/L硝酸银溶液中，不断搅拌最后得到亮白色稳定纳米银溶胶，将步骤一得到的改性棉织物浸渍在纳米银溶胶中5-10min，通过巯基的络合作用固定纳米银，取出后60-80℃烘干，清洗，然后在烘箱中烘干，获得抗菌棉织物。上述发明是用半胱氨酸盐酸盐改性棉织物表面增强纳米银抗菌棉织物耐洗性能的方法，使半胱氨酸羧基与纤维素羟基发生酯化反应从而将其键接到棉织物表面，再使纳米银与改性棉织物表面巯基发生络合作用，固定纳米银颗粒。上述发明虽对棉织物表面进行改性增强纳米银的耐水洗性，但使用半胱氨酸羧基与纤维素羟基发生酯化反应将其键接到棉织物表面，制备工艺复杂，很难用于大规模低成本的生产实践。
因此，本发明提供一种非浸泡的抗菌防臭棉的制备工艺，制得抗菌性能、耐水洗性能非常优异的棉织物，制备工艺简单，适用于工业化生产。

更进一步地，所述二乙烯三胺-乙醇溶液、六水合硝酸锌溶液和硝酸银溶液组成的混合溶液为二乙烯三胺-乙醇溶液、六水合硝酸锌溶液、硝酸银溶液按质量比1.5:1.2-2.5:2.5-4组成，混合溶液pH值为10-11。

(2)本发明采用共混纺丝工艺对聚酰胺纤维进行抗菌处理，添加薄荷脑具有防臭抗菌性能。非浸泡抗菌防臭棉由抗菌棉纤维与抗菌聚酰胺纤维混纺而成，具有吸汗、速干、广谱抗菌、长效杀菌性、防臭性能，安全且具有良好的耐水洗性。
