Development of Laminated Protective Fabric with Fluorescent Water-proof and Moisture-permeable Properties
Abstract: In this paper, a new kind of protective fabric with fluorescent water-proof and moisture-permeable properties is developed by laminating the fluorescent water-proof and moisture-permeable PU film prepared by mixing rare-earth strontium aluminate into polyurethane adhesive with the fine nylon substrate by way of transfer coating with release paper. The selection of the substrate and adhesive, the preparation of the film and the laminating process are introduced in details; the fluorescent performance and the water-proof and moisture-permeable properties are tested. The test results show that the laminated fabric can meet the requirements for making protective clothes.

目前消防、交警、船舶工勤人员等特种作业人员的工作环境往往为夜晚等寒冷、雨雪或大风等恶劣天气,其防护服必须具有荧光、防水透湿等多种功能。基于此,以稀土铝酸锶和PU为原料,本文开发了一款荧光防水透湿特种防护面料。
1 生产工艺
将掺杂稀土铝酸锶粉末的PU面层胶料涂覆于离型纸上烘干形成面层,将掺杂稀土铝酸锶粉末的PU底层胶料涂覆于面层,并半烘干形成粘结层,将基布和粘结层贴合、熟成,剥离离型纸后得荧光防水透湿面料,生产工艺见图 1。
1.1 基布选择
基布是开发荧光防水透湿面料的基础,必须具有平整细密、坚牢耐磨、色泽鲜艳、易洗快干和防风等特点。尼丝纺为锦纶长丝制织的纺类丝织物,具有平整细密,手感柔软,轻薄而坚牢耐磨,色泽鲜艳等特性。为此,以380 T尼丝纺印花面料(经纬丝:20 D锦纶长丝,经纬密:200根/英寸× 180根/英寸,幅宽:150 cm,克重:38 g/m2,织物组织:平纹)作为基布。
1.2 胶料制备
面层起主要的荧光防水透湿功能,因此面层胶料应选择滑移和抗阻塞性好的一液型单组份油性PU树脂,而底层作为和基布的粘结层,底层胶料应选用较柔软的60% ~80%高固型份的二液型油性PU树脂。……
