1、外文翻译一-测定织物液态水动 态传递的新测试方法的精度测定织物液态水动态传递的新测试方法的精度摘要一项由 AATCC（American Association of Textile Chemists and Colorists, 美国纺织化学师与印染师协会）最近提出的测试法解决了测试纺织面料和其他 多孔材料的吸湿导汗性能这一难题。这项测试方法和依照这项方法设计的仪器, 吸湿导汗性能测试仪（MMT）,以及评估指标的定义和等级，连同织物吸湿导汗 性能的分级方法都得到了改进。此项测试的样品为8块面料。这8块面料的结 构特征、材料各不相同，其中部分面料所使用的染整工艺不同。本文还对此方 法与其他测试方
