Factors Affecting The Colour Yield Of An Acid Dye On Nylon Fabric

ABSTRACT The factors that affect the colour yield of an acid dye on nylon fabric were investigated at a constant temperature of 500C, usingC.I. Acid Yellow 23,with citric acid and sodium chloride as auxiliaries. It was observed from the absorbance results that the colour yield of C.I. Acid Yellow 23 improved with increase in time of dyeing, while the absence or increase beyond 1% (acid) and 5% (salt) reduced the colour yield of the acid dye on the nylon fabric. Also, at a constant dyeing...
