Abstract
提供一种持久抗菌防污纺织品及其制备方法。所述纺织品上附有通式(I)或(II)的异氰酸酯甜菜碱型抗菌防污化合物。该纺织品具有持久的抗菌活性、耐洗性以及很强的亲水性。
Description
本发明涉及一种纺织品及其制备方法,更具体地,涉及一种持久抗菌防污纺织品及其制备方法。
纺织品能吸收人体分泌的汗液、皮脂等排出物,在温度和湿度合适的环境下,寄居在纺织品上的微生物可大量繁殖,分解人体分泌物,产生氨等带有异味的物质,或在织物上生成菌斑,以致在穿着或应用过程中,对人体产生不适或不良影响,使纺织品产生霉变、脆化甚至变质。随着社会的发展和人们生活水平的提高,产生了新的市场需求,消费者希望纺织品具有抗菌功能,
以满足文明舒适的生活需要。在纺织品中,天然纤维比合成纤维吸湿排汗性能好且穿着舒适,人们的内衣、袜子、毛巾、床单等贴身衣物绝大部分采用天然纤维材料,所以天然纤维材料成为抗菌织物的主流产品。抗菌织物是指在不改变织物本身感官或物理化学性状(
如强度、吸水性、手感、色差)
的前提下,运用各种抗菌剂对织物进行抗菌加工,不仅使纤维材料本身能抵抗微生物分解变质,也能使附着在织物上的微生物丧失活力或不过度繁殖,提高了纺织品的品质和消费者的生活质量,使抗菌织物也进入了家庭消费品行列。
目前市场上的抗菌制品,基本上是采用三种方法产生:一是先将抗菌剂加入纺丝材料中制成抗菌纤维,然后制成各种抗菌纺织品。该法抗菌效果持久,耐洗性好,但是技术含量高,难度大,涉及领域广,对抗菌剂要求高;常用来生产合成类纤维类产品。二是在织物印染后整理过程中加入抗菌剂(常被称为抗菌整理剂),然后制成各种抗菌纺织品。该法加工处理较为简单,而耐洗性及抗菌效果持久性较差。三是先将抗菌剂加入到纺丝材料中制成抗菌纤维,再在织物印染后整理过程中加入抗菌整理剂,然后制成各种抗菌纺织品,这种方法仅在具有高抗菌性能要求的特殊产品中使用,限制了使用范围。
本发明所要解决的技术问题是,为了克服现有技术中纺织品抗菌效果持久性差的问题,提供一种新颖的持久抗菌防污纺织品。该纺织品具有高效的抗菌效果,且具有很强的耐洗性以及抗菌效果持久;此外,该纺织品的制备方法简单,适合于大规模推广应用。
