Description

天然抗菌消臭棉织物的制备方法 技术领域
[0001] 本发明涉及一种抗菌消臭棉织物的制备方法。
背景技术
[0002] 随着生活水平的提高， 人们越来越关心健康和清洁问题， 对于纺织品的要求也 不再仅仅局限于穿着装饰， 对卫生清洁保健等功能的需求不断提高。
[0003] 目前抗菌剂中化学合成的较多， 在抗菌的同吋对人体健康的影响也备受关注。
一般抗菌防臭产品主要是通过抗菌剂抑制细菌生长来达到防止臭味产生的目的 。 但日常生活中已经存在的不愉快汗味、 体臭、 烟臭味、 新房装修中产生的挥 发性有机物异味， 严重污染了清新的空气， 影响了人们的生活环境和身心健康 ， 特别是伴随老齢化社会的到来， 卧床的老齢者增多， 对防止恶臭措施的要求 也随之增高， 这些都促进了消臭整理的迅速发展。 纺织品除 （消） 臭整理的方 法和机理主要有:感觉除臭法 (掩盖法)、 物理除臭法 (吸附法)、 化学除臭法、 生物 除臭法等。 目前市场上活性炭等吸附性消臭剂， 在吸附臭气中不能分解破坏臭 气， 必须及吋脱附， 否则易解析造成对环境的多次重复污染。 随着人们环保意 识的不断增强和科学研究的不断深入， 人们己经认识到合成的抗菌、 消臭剂对 人体和环境存在潜在的危害。 因此， 我们急需寻找和幵发高效的天然物质作为 抗菌、 消臭剂来替代人工合成的化学整理剂。
[0004] 植物是生物活性物质的天然宝库， 其产生的次生代谢产物超过 40多万， 其中的 一些化学物质具有杀虫、 杀菌、 消臭的效果， 幵发新型植物源抗菌、 消臭剂已 成为目前研究的热点之一。 天然抗菌、 消臭材料无毒无害， 对皮肤无过敏性和 致癌性， 具有较好的可降解性和环境相容性， 符合当今纺织品生态纺织发展要 求， 因此将织物与天然抗菌成分结合起来做成抗菌环保的功能性纺织品有着重 要的意义。 用天然药用植物的提取物作为功能抗菌、 消臭整理剂， 对纺织品加 工， 可达到抗菌、 消臭、 保湿、 吸湿、 改善肌肤触感、 抗过敏、 治皮炎等功效 ， 这是一种保健、 舒适的加工方法。 [0005] 茶多酚具有天然抗菌功能， 并通过对臭气的分解达到消臭效果。 目前存在的问 题是对棉的吸附性很差。
