| dc.description.abstract | The present study was conducted to standardize dyeing process of reactive dye for cotton using tie and dye technique. Red hot reactive dye was selected for dyeing of white cotton fabric. Standardization of dyeing variables viz, dye concentration, dyeing temperature, dyeing time, dyeing pH and different auxiliaries concentrations were optimized on the basis of percent dye absorption and visual appearance. Colour fastness properties of tie-dyed samples were also evaluated regarding washing, sunlight, perspiration and rubbing fastness. It is summarized that 4 percent was the optimum dye concentration on the basis of maximum percent dye absorption whereas on the basis of colour fastness 2 percent was optimized. Thus 2 and 4 percent were selected as light and medium shades of red reactive dye. The optimum dyeing temperature was 80°C, time was 90 minutes and pH was 10.5 for both the dye concentrations. 60g/l of sodium sulphate concentration was selected for 2% dye concentration and 70g/l for 4% dye concentration as it gave maximum dye absorption. 15 g/l concentration of sodium carbonate was selected for 2% dye concentration and 20g/l for 4% dye concentration as it gave maximum dye absorption Samples were tied and dyed with the standardized dyeing conditions and dyed samples were assessed for their colour fastness properties. Samples with 2 percent dye concentration gave better colour fastness properties than 4 percent dye concentration. Shopping bags were developed by object binding, knotting and leharia technique using reactive dye were highly appreciated by the experts as well as consumers. Training on use of hot reactive dyes for tie and dye technique using standardized dyeing conditions was imparted to rural women. Training was found to be very effective as there was significant gain in knowledge. | en_US |
