Description

一种阻燃防刀割布及其制备方法
技术领域
本发明涉及一种阻燃防刀割布及其制备方法，属于纺织材料与防护材料技术领域。
背景技术
和平与发展是世界的两大主题，也是我们国家的主题。但是在社会主义经济建设繁荣发展的今天，在我们日常生活中，仍然存在着许多不稳定的因素，例如持刀抢劫、盗窃等案件时有发生，这严重威胁着我国公民的人身安全，与此同时，更是严重威胁着我国执法人员的人身安全。如何在与持刀的歹徒、罪犯搏斗过程中更好地保护执法人员的生命安全，成为越来越被人关注的热点问题。因此，防刀割服装也因而面临着紧迫的需求。
然而，常规的服装用纺织材料都不能有效防范刀割，目前市面上有防刀割手套、防刀割包等产品，多采用夹层、涂层结构，这种结构材料不适合做服装用，目前尚未有真正意义上适合做服装用的防刀割全纺织材料或防刀割布的相关应用报道。
一款优异的服装用防刀割布料，不仅要首先保证其优异的防刀割性能，还要保证布料的透气性、柔软性与舒适性，并具有对高温、火灾等多复杂环境的适应能力，这对于保障执法人员的工作质量具有重大意义；与此同时，发明一款能够真正可以用于防刀割的服装用布料，具有重大的市场经济意义和社会意义，为我国社会主义经济和谐、健康、快速、稳定发展提供强有力的保障。
