Influence of Low Temperature Dyeing Accelerant on Acrylic Fiber Dyed with Cationic Dyes

The dyeing behavior of cationic dyes to acrylic fiber with self-made low temperature dyeing accelerant was investigated in this study.Compared with conventional dyeing,the acrylic yarn was dyed with Cationic Turquoise Blue X-GB at 85℃ in the presence of accelerant and absence of accelerant,respectively.The influence of low temperature dyeing accelerant on the dyeing mechanism of acrylic fiber dyed with cationic dye was analyzed through kinetics and thermodynamics study.The results show that adding dyeing accelerant can heighten the equilibrium dye-uptake,dyeing rate constants,diffusion coefficients,and shorten half-dyeing time for acrylic fiber dyed with cationic dyes.Furthermore,the partition coefficient,the standard affinity,and the dye saturation value also increased in the dyeing at 85 ℃.
