Abstract

Nowadays, synthetic dyes are commonly used as colouring agent. Synthetic dyes have superior properties related to natural dyes such as brighter colouration, more fadeproof and cheaper. However, synthetic dyes are considered as nonevironmental-friendly chemicals. Therefor, it is suggested to use natural dyes that have environmental-friendly properties as colouring agent. Aim of this study was to find the best fixer chemical between Al2(SO4)3 solution, Ca(OH)2 solution, and C6H8O7 solution. Natural dye which was applied to mordanted white cloth was then fixed using above fixer chemicals. Fadeproof and rubproof of each coloured cloth was then measured.
