Sulfur Dyeing With Non-Sulfide Reducing Agents

Amit Madhu


Sulfur dyeing realized as the most economical and the promising way to obtain heavy shades on cellulosic in industries. Traditional sulfur dyeing is done with sodium sulphide as reducing agent which is the major reason for effluent. In this study we employed reducing sugars for sulfur dyeing and compared with conventional one. The cotton fabric is subsequently dyed with sulfur black and brown dyes using glucose and fructose reducing sugar. Comparable color strength with good wash fastness is observed with these non sulphide reducing agents.
