Colorimetric properties of batik fabrics colored using gambier liquid waste

The process of batik and colouring on cotton and silk using gambier liquid waste, through the wax removal process in hot temperature affects the color characteristic and fastness properties of the fabric. The purpose was to study the effects of the batik process on the color and fastness properties the dyed fabrics. The study was conducted with the use of soda ash as the wax removal, and CaO, FeSO 4, Al 2 (SO 4 ) 3 as mordant with post mordanting method on cotton and silk fabrics. The results showed that the batik process affects the can provide varying color strength (3.7 - 16.7) with color coordinates in the range of yellowish (7.7 - 19.9) to reddish (5.7 - 24.8) and fairly good color fastness to excellent against washing, rubbing and light effects. The highest color strength was obtained when using mordant FeSO 4 which was applied to silk.
