Optimization of non-aqueous and less water dyeing process of cotton fabric by response surface methodology
In order to improve the fixation rate of reactive dyes,response surface methodology was used to optimize the dyeing process of cotton fabric in D5 system in non-aqueous and less water medium.The interaction among sodium carbonate concentration,fixation time and fixation temperature was studied,and the optimum process parameters were optimized:sodium carbonate concentration 48 g/L,fixation time 10min and fixation temperature 89℃.According to the optimum process conditions,the predicted fixation rate is 75.67%.The fixation rate calculated by experiment is 76.73%,which is consistent with the predicted value.
