This research aims to the ability of indigo discharge printing for the Denim with Eco-friendly materials showing the impact of the preparation material’s (Potassium permanganate ), use, and its influence’s knowledge on the fabrics in the in the study’s situation, as the importance of this research is cleared in the ability of the functional properties on the Denim by using discharge printing to advance the level’s quality of the final product and the energy and resources consuming limit that has an environmental feedback, as well as suitable fabrics were produced for this reason with various sizes of weft and warp yarns, whereas the descriptions of these yarns were constant in all the produced fabrics under the research: cotton 100% but with different numbers 8/1, 12/1, 16/1 and the cotton warp 100% with various numbers 8/1, 12/1, 16/1 by using 17 picks/cm, by using weave structure (twill 1/2), and after the first preparations’ procedure on the produced fabrics that were done under the research according to the specific changes and descriptions. Then it was done by a printed dough which is made of artificial thickener with the addition of the Potassium permanganate material, with three concentration (2%, 4%, 6%), and the drying was done on the room’s temperature, then washing samples with water which contain sodium meta bisulfite (a helper material) that helps in breaking the permanganate, after that, . The results were analyzed statistically using analysis of variance, to obtain correlation, in addition to use ( radar-chart multi-axis ) which was used to evaluate quality of clothes produced under study . The results reveal that the fabrics under the weave structure Twill 2/1 with warp yarn 16/1 cotton and weft yarn 12/1 cotton after treated by Potassium permanganate, (2%) is the best ever for all performance by factor of quality 99.24And the least samples produced under research were the weave structure Twill 2/1 with warp yarn 12/1 cotton and weft yarn 16/1 cotton after treated by Potassium permanganate, (6%) by factor of quality 84.20
