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,EandF.By examing the behavior of step dyeing with compatibility of color matching,the relation ship between S,R,Eand Fvalue and the dye absorption rate,fixation rate and compatibility of dyes was discussed.The compatibility of dyes was inferred by the similarity ofS,R,EandFradar graphics.The samples dyed for different durations indicated thatS,R,Eand Fhave great influence on color matching and provide important guide to the selection of dyes for compatibility.
