耐光汗复合色牢度测试方法的改进

Improvement of Testing Method for Complex Colorfastness to Light and Perspiration

介绍了耐光汗复合色牢度的测试原理,指出国标CBB/T14576—2009《纺织品色牢度试验耐光、汗复合色牢度》中关于耐光汗复合色牢度检测方法的不足,并从人工汗液组分、曝晒方式这两个方面进行了探讨与改进。对比分析表明,日本ATTS(纤维制品技术研究会)测试标准中规定的人工汗液组分更接近人体的真实汗液,SN/T1461—2004《进出口纺织品耐光、汗复合色牢度试验方法》标准中试样采用包裹法更能保持其湿度;结合这两种测试方法的优点对20种颜色的试样进行试验,数据显示,所测得的检测结果比国标法测试的相应等级均低。

The testing principle of complex colorfastness to light and perspiration were introduced, the deficien- cy of testing this complex colorfastness using national standard GB/T 14576--2009 Textile Colo@~stness to Light and Perspiration were analyzed, and the improvement were discussed though factors of synthetic perspiration compo- nent and the exposure way to light. The results show that the synthetic perspiration specified in the Japan Ar[TS （Automatic Target Tracking System） Standard is much closer to the human body actual perspiration; the method of wrapping samples when testing formulated in SN/T 1461--2004 Import and Export Textiles Colorfastness to Light and Perspiration Test Method is good and can maintain the humidity of samples efectively. Conducted experiment to test complex color fastness to light and perspiration by using these two methods together, it is found that the re- sults are more tit to the customer＇s practical dressing requirements.
