摘　　要：针对丝棉织物染色同色性差的问题,采用M型活性染料对丝棉织物进行同浴染色,探究了丝棉比例以及染色条件(盐浓度、碱浓度、棉上染时间、棉固色时间、真丝染色pH值)对染色同色性的影响。结果表明:随着棉纤维比例的增大,棉织物和真丝织物的同色性变差;不同比例的丝棉织物同浴染色时,所适用的染色工艺条件不同;丝棉织物的色差ΔE1均在2.00左右,固色率均达到70%左右,耐皂洗色牢度和耐干、湿摩擦色牢度等级均达到4级及以上。In order to solve the problem of poor same color property of silk/cotton fabrics,M-type reactive dyes were used to dye silk cotton fabrics in the same bath,and the effects of silk cotton ratio and dyeing conditions(salt concentration,alkali concentration,cotton dyeing time,cotton fixing time,and silk dyeing pH value)on the same color property were explored.The results show that the same color property of cotton fabrics and silk fabrics deteriorates with the increase of the proportion of cotton fibers.When silk and cotton fabrics are dyed in the same bath with different properties,different dyeing process conditions should be applied.The color difference between cotton fabric and silk fabric are about 2.00,the color fixation rate are about 70%,and the washing fastness and wet and dry rubbing fastness are both equal to or higher than grade 4.
