Abstract

This research aims to: (1) determine the optimum ratio of ethanol-water for the extraction of tannin from soursop leaves, (2) determine the optimum time for the extraction of tannin from soursop leaves, (3) determine the proper fixation material to produce optimal color fastness of natural dyes tannin from soursop leaves, dan (4) find a natural dye from soursop leaves that can be applied as a natural dye in textiles with high quality and environmentally friendly. This research used experimental method. Soursop leaf was extracted using soxhletation methods at 80oC (rasio of ethanol-water = 1:1, 1:2, 1:4, extraction time = 1, 2, 3 hours). The tannin qualitative test done with FeCl3 method.. The tannin quantitative test done with Folin-Ciocalteu method. Dyeing process included mordanting , coloring, fixation (with Tunjung, chalk, and Tawas). The color fastness was tested with Laundrymeter and Crockmeter. The research concluded that: (1) the optimum ratio of ethanol-water for extraction of tannins from soursop leaves is 1: 1, (2) the optimum time for extraction of tannin from soursop leaves is 2 hours, (3) fixation material that produces optimal color fastness of natural dyes soursop leaves is tawas
