Abstract:
In this study, three different bleaching recipes (Full bleaching, Half bleaching, No bleaching) were used on 100% cotton S/J fabric samples before dyeing them in different shades (0.5%, 1%, 1.5% & 2%) using reactive dye to verify possible changes in color of depth of fabric sample. Bleaching agent used in this study is 50% H2O2. The color strength (K/S value), Wash fastness, Dry & Wet rubbing fastness, Water fastness & CMC decision were evaluated after the dyeing process. The findings that were collected after testing shows that the Full bleached fabric sample were better than the half & no bleached fabric sample. Half bleached & no bleached fabric sample were more redder or greener and less saturated in shade than full bleached fabric sample. The entire set of full bleached, half bleached & no bleached dyed samples demonstrated good wash and rubbing fastness over a spectrum of different shades.
