| Abstract | ||||
| This work focuses on the effect of enzymatic treatment sequence on the natural dye absorption by cellulosic fabrics. The extent of enzymatic treatment and the dye absorption by cellulose fabrics without seriously affecting its mechanical properties were studied. Attempts have been made to modify the conventional enzymatic treatment sequence of cellulose fabrics, i.e. enzymatic treatment and post dyeing in separate two baths, or dyeing and post enzymatic treatment, using three natural dyes, Curcuma Turmeric, Henna, and Tea. Enzyme treatment enhanced the natural dye absorption and gave the highest results in terms of dye fastness. The extents of bio-attacked as well as dye ability using Cellulosic fabrics with different weaving structure under investigated follows the decreasing order: Lenin > fibran > cotton. The differences among these substrates inweaving structure for a given enzyme treatment condition, decrease in the depth of shade, K/S, follows the descending order: Henna dye > Tea dye > curcuma Turmeric dye. Further reveals that the effect of the used mordents on the depth of shade, K/S, follows the descending order: Chrome > alum> tin. | ||||
