DIFFERENCES IN TAMARIND, KANDIS ACID AND BELIMBING WULUH MORDANTS ON THE DYEING RESULTS OF KEDONDONG PAGAR (LANNEA NIGRITANA) BARK EXTRACT ON COTTON MATERIAL

Abstract

The absorbency of the dye is affected by the mordant. Mordant can be an acid. This study aims to describe the difference of Mordant on the results of dyeing kedondong pagar stem bark extract on cotton material. This type of research is experimental research. This study uses primary data derived from 15 panellists, analysed by Friedman K-related Sample test with Statistical Product And Service Solution application. The results of dyeing with tamarind mordant produced Clam Shell Pink colour #D2AAA0. Colour lightness is quite bright. Washing resistance in the first and second wash the colour has no change at all, the third wash the colour changes slightly or decreases. The result of dyeing with kandis acid mordant produces the colour Clam Shell Pink #E1B19F. The colour is very light. Washing resistance in the first and second wash the colour slightly changes or decreases, the third wash the colour looks changed or reduced. The result of dyeing with belimbing wuluh mordant produces Warm Brown colour #D3A599. Light dark colour. Washing resistance in the first wash the colour has no change at all, in the second wash and the third wash the colour slightly changes or decreases. The results of the analysis of the Friedman K-related Sample test for light dark colour with a significance value < the significance level = 0.000 < 0.05 with the result that Hₐ is accepted and H 0 is rejected, meaning there is a significant difference. washing resistance is a significance value < the significance level = 0.00 < 0.05 with the result that Hₐ is accepted and H₀ is rejected, meaning there is a significant difference. It can be concluded that there is a difference in the mordant of tamarind, kandis acid and belimbing wuluh on the dyeing of kedondong pagar bark extract.
