Description Not Available
Jute fabric was dyed with several direct dyes and thereafter applied selective aftertreatment like copper sulphate/potassium dichromate, dye fixing agent, etc. Evaluation of dyed samples using a computerised colour matching system shows a appreciable improvement of colour strength in fabrics treated with a dye fixing agent, while a decreasing trend was observed in case of fabrics treated with copper sulphate/potassium dichromate. Aftertreatment with copper sulphate/potassium dichromate and with dye fixing agents results in improvement of washing fastness as measured by computer colour matching system. Dyes which have wave length of maximum absorption (λmax) in the lower side of the visible range show higher light fastness property. A marginal improvement of light fastness was achieved in case of copper sulphate/potassium dichromate treatment while a marginal decrease in light fastness was observed in case of dye fixing agent treatment.
