5反胶束体系活性染料染色研究

iming at the high concentration electrolyte pollution of reactive dyeing, level dyeing property and K/S value of dyed fabrics were used as evaluation indexes for selecting out the D5 reverse micelle dyeing process as follows: the Na2CO3 concentration of 40g/L and process duration of 30min. The influences of water content W0 of reverse micelle and addition of neutral electrolyte Na2SO4 on the reactive dyeing were investigated, and the results indicated that K/S value of dyed fabrics decreased with the increase of W0 at the same dye concentration(%o.w.f), Na2SO4 had no promotion effect on reactive dyeing in D5 reverse micelle system, which can realize \\\"salt-free dyeing\\\" of reactive.
