摘　　要：介绍了GB/T 14576—2009《纺织品色牢度试验耐光、汗复合色牢度》的测试方法,并对其不同测试方法进行了差异分析。试验结果表明,织物对酸、碱的敏感程度不同,且对于大多数产品来说,其耐碱性最差;此外,在酸性条件下,酸性越强,织物的变色越严重,而该标准中酸性汗液有两种,二者的配制及pH存在差异,故而二者试验结果不等效,不可互换。因此,为了更规范且避免分歧,应注明所使用的酸性汗液种类。希望对第三方检测机构、企业在质控方面给予一定的指导。The test methods of GB/T 14576—2009 textiles-tests for color fastness-colour fastness to light of textiles wetted with artificial perspiration were introduced, and different test methods were analyzed. The test results showed that the fabrics had different sensitivity to acid and alkali, and for most products, it was the least resistant to alkali. Moreover, under acidic conditions, the stronger the acidity was, the more serious the discoloration of the fabric was. However, there were two types of acidic sweat in this standard, and they were different to the preparation and pH value, so the test results were not equivalent and could not be interrupted. Therefore, in order to be more standardized and avoid controversy, the type of acidic sweat used should be indicated, to give some guidance to third-party testing institutions and enterprise quality control.
