摘　　要：研究了7种常用偶氮类活性染料染色棉织物在光、汗复合条件下的褪色情况,系统分析了ISO、AATCC和ATTS标准汗液、AATCC汗液组分、光源功率、照射波长、空气组分以及染料用量对偶氮类活性染料染色织物耐光、汗复合色牢度的影响.结果表明,ATTS标准汗液为测试汗液时,染色织物光汗褪色最严重;AATCC汗液组分中,组氨酸、乳酸和氯化钠对染料耐光汗牢度都有明显影响,其中氯化钠影响最大;光源功率越大,染色织物褪色越快;在汗液存在条件下,可见光和紫外光都导致了染色织物的褪色;氧气浓度的增加加剧了染色织物的褪色;随着染料用量的增加,染色织物的耐光、汗牢度均有所提高.The color fading of seven conventional reactive azo-dyed cotton fabrics under combination ac- tion of perspiration and light were investigated. The effects of standard perspiration of ISO, AATCC and ATTS, perspiration components of AATCC, light source power, radiation wavelengths, air component and dye concen- trations on the color fastness to perspiration and light were systematically analyzed. The results showed that the perspiration of ATTS had the most obvious effect on color fading of reactive azo-dyes on cotton. L-histi- dine, lactic acid and sodium chloride in AATCC perspiration all influenced the color fastness, and sodium chlo- ride played the most important role. All dyes faded faster as the light source power got stronger. Visible light and ultraviolet light both contributed to the light-perspiration fading. The increase of oxygen concentration was helpful to the color fading of dyed fabric. The color fastness to combination of perspiration and light in- creased with increasing dye concentrations.
