Salt-free Dyeing of Cotton Woven Fabric with Reactive Dyes in Triton X-100 Reverse Micellar Media

摘要

The nonionic reverse micelles used for dyeing cotton fiber were prepared with a non-ionic surfactant Triton X-100 (TX-100) by injecting small amount of reactive dye aqueous solution. The percentage of dye bath exhaustion in TX-100 reverse micelles and in bulk water was carried out and compared, respectively. The effect of inorganic salt was also discussed. The results indicated that the dyeing properties of the reactive dyes on cotton fabric increased with decreasing NaCl concentration and increasing initial dye concentration in TX-100 reverse micelle. The percentage of dye bath exhaustion obtained in reverse micelles was higher than that in bulk water.
