Abstract:
Sodium dithionite (Na2S2O4) is a conventional reducing agent for indigo dyeing with
cotton in an alkaline solution in order to reduce an indigo pigment to a water soluble leuco
form. In this study, three monosaccharides (glucose, fructose and galactose) were studied as
eco-friendly reducing agents to compare with Na2S2O4. Two alkaline media: NaOH and
Ca(OH)2 were applied in the reducing system. The optimum condition for reduction of
natural indigo was found at 50oC and 30 min. The results showed that surface and crosssection
of the dyed cotton fabrics using Na2S2O4 and monosaccharides as reducing agents in
NaOH solution could give darker blue shade than in Ca(OH)2 solution. In addition, color
strengths (K/S) of fabrics in NaOH medium from glucose were higher than the ones from
other reducing sugars and Na2S2O4. On the other hand, Na2S2O4 gave higher color strength
fabrics than that from monosaccharides in Ca(OH)2 solution. From the build-up study, shade
depths of cotton fabrics increased as indigo concentrations in the dyebath were raised.
Therefore, monosaccharides could effectively use as green reducing agents in NaOH solution
for natural indigo dyeing on cotton fabrics.
