Abstract

This research was done to exploit the extract of Ageratum conyzoides leaf as natural dyes on primissima cotton using Citrus aurantifolia, Al2(SO4)3, Ca(OH)2, and FeSO4 as mordant. Ageratum conyzoides was extracted using water as solvent in ratio of 1:10 with pre-mordanting method. The results of the dyed fabric was analyzed using various testing parameter such as rubbing color fastness and washing color fastness properties.The mordant materials affecting the color shade and the pH affecting the color strength. The color shade was yellow to dark yellow-green-grey. Color fastness on wet and dry rubbing showed the “good” value, while the value of color fastness to washing in the category “enough”. Based on the results, it can be concluded that the extract of Ageratum conyzoides leaf can be used as a natural dyes in primissima cotton fabric
