活性染料染色特征参数在染料配伍选择中的应用

 为测定不同实验组染料的S、R、E、F值，选用不同组合的高温型活性染料，按设计的工艺条件染纯棉织物。以实验组染料的渐进上染性能与拼色配伍性关系为对照，讨论S、R、E、F值与染料的吸附速度、固着效率及配伍性能的关系。采用比较S、R、E、F值雷达图形相似程度的方法，推测染料的配伍性能。用不同S、R、E、F值的染料组合进行拼色染色，不同时段的取样结果表明，染料的S、R、E、F值对拼色效果存在较大的影响。实验结果证明, 活性染料的染色特征值（S、R、E、F值）对于染料的配伍选择具有重要的指导意义。

Application of dyeing parameters in compatibility selection of reactive dyes

Three groups of high temperature reactive dyestuffs were chosen to dye cotton fabric according to designed process conditions for getting their dyeing parameters S,R,E and F.By examing the behavior of step dyeing with compatibility of color matching,the relationship between S,R,E and F value and the dye absorption rate,fixation rate and compatibility of dyes was discussed.The compatibility of dyes was inferred by the similarity of S,R,E and F radar graphics.The samples dyed for different durations indicated that S,R,E and F have great influence on color matching and provide important guide to the selection of dyes for compatibility.
