对实施例一及实施例二、对比例所制备的仿羊皮面料进行防色迁移测试,包括耐升华牢度和耐贮存色牢度。
当温度达到一定温度时,纤维里的染料从粉末状固体直接变成气体逸出,而逸出的染料遇冷后又凝结成固体,沾到织物表面或其他织物上,通常表现为分散染料,这是一种热迁移现象,也是常称的耐升华牢度,一般采用耐干热(热压除外)色牢度进行测试。耐升华牢度的测试标准为:GB/T 5718-1997《纺织品色牢度试验耐干热(热压除外)色牢度》。
当温度低于染料升华温度和不能升华的染料情况时,不同颜色组成的织物在储存或使用中发生染料由一处向另一处迁移,通常是深色部分向浅色部分转移,通常这种现象称为染料迁移(色迁移),可用染料转移性能或耐贮存色牢度测试。耐贮存色牢度测试标准为GB/T 32008-2015《纺织品色牢度试验耐贮存色牢度》。方法概述:将待测试样与预湿的多纤维贴衬或指定织物形成组合,组合试样夹到耐汗渍色牢度仪试验架中并固定好试验架,将试验架放入规定的试验条件的恒温恒湿装置中,用灰色样卡评定试样的变色和多纤维贴衬或指定织物的沾色。试验条件是24±2℃、相对湿度为80±5%,时间为48小时。
测试结果如下:
实施例一 实施例二 对比例
耐升华牢度 4 4 2-3
耐贮存色牢度 4-5 4-5 3
可见实施例一及实施例二所制备的烫金面料具有良好的防色迁移效果。
以上详细描述了本发明的较佳具体实施例。应当理解,本领域的普通技术人员无需创造性劳动就可以根据本发明的构思做出诸多修改和变化。因此,凡本技术领域中技术人员依本发明的构思在现有技术的基础上通过逻辑分析、推理或者有限的实验可以得到的技术方案,皆应在由权利要求书所确定的保护范围内。
