Reverse micellar dyeing of cotton fabrics with PEG-based non-ionic surfactant in heptane non-aqueous medium with the use of reactive dyes with different reactive groups was investigated. Single jersey knitted fabrics were used in this study. The experimental results reveal that samples dyed by both one-bath and two-bath heptane reverse micellar methods can achieve higher colour yield than the conventional...
Use of reactive dyes of red, blue and yellow colours for exhaustion dyeing of cotton conventional water-based dyeing method and PEG-based solvent-assisted reverse micelle dyeing method was investigated. Calibration curves of both dyeing approaches were established. The calibration results show that red dye can achieve higher absorbance value than yellow and blue dyes and the R-square of the curves...
The effect of hydrophilic-lipophilic balance (HLB) of polyethylene glycol-based non-ionic surfactants of polyoxyethylene stearyl ether and polyoxyethylene tridecyl ether series of seven types on reverse micellar dyeing system of cotton was studied in non-aqueous heptane solvent medium. The relationships between HLB values of surfactants and reflectance, K/Ssum value and levelness of the dyed samples...
