摘　　要：兰纳素红系列染料在弱酸浴中上染羊绒具有颜色艳丽、匀染性好等优点,但是由于染料自身结构的原因,导致这一系列染料的耐汗渍牢度不高。针对这一问题,在企业实际染色工艺的基础上采用色牢度提升剂雅可固,通过调节p H值,保温时间,后处理保温温度等一系列工艺优化来提高耐汗渍色牢度,通过实验得出兰纳素红6G是系列染料中最优的染料;兰纳素红B羊绒染色后进行酸处理,然后在p H值5,雅可固3%(owf),40℃下后处理,得色牢度最佳;兰纳素红5B上染羊绒提高耐汗渍色牢度的方案为染色后进行酸处理,然后再加雅可固处理,其中雅可固用量为2%(owf),保温温度为40℃,p H值5。Cashmere dyed with Lanasol red reactive dyes has the advantages of bright color, good levelness etc. Due to differences in dye their own performance, the fastness of the Lanasol red dyes to perspiration is not high. Aimed at this problem, Jacobian solid color fastness and color fastness promoting agent are used in improving the fastness to perspiration, by adjusting the pH value, the holding time. The dyeing of cashmere Lanasol red B treatment stage optimal process parameters value after heat treatment temperature is 40 ℃, pH value 5, yake solid dosage is 3% （owl）. For dyeing of cashmere Lanasol red 5B processing stage optimal process parameters value after heat treatment temperature is 40℃ , pH value 5, yake solid dosage is 2% （owf）.
