Abstract

This research deals with treatment of cellulosic clothes fabrics (cotton-linen) with SLN PERIWET (fatty alcohol polyglycol ether and phosphoric acid ester) at four different concentrations (5, 10, 15, 25 g) before the dyeing process so that dyeing process procedures were conducted with a natural dye extracted from sumac under the following dyeing conditions: dye concentration of 2.5 g/l, temperature 100 ° ± 3 ° C and time of 60 minutes in the presence of a mixture of mineral stabilizers, a ferrous sulfate + potassium chromate as a concentration of 25 g / l.
At the end of the experiment, tests were performed on the dyed material, namely color depth test (K/S) and fastness to (light-washing-friction). Grading of strong and bright colors was obtained and the results showed clear values ​​to the impact of treatment material, where samples gave values ​​of color depth and higher degrees of fastness than those samples that have not been treated. Therefore, the research recommends using natural dyes due to the recently proven serious damage of artificial dyes and their carcinogenic effect on human health and harmful impact on the environment. The researcher also recommends the necessity of environmentally safe treatment of the material to allow better permeability of natural dyes and getting strong, bright and faster colors
