Abstract

A novel printing paste for linen and viscose fabrics with reactive dyes was applied attempting to tackle the issue of water contamination caused by using urea excessively in cellulosic fabric reactive dye printing. This novel paste eliminated urea entirely and allowed for the maximum fixation of reactive dyes on the fabrics. In place of 150g/kg urea, an amalgamation of nonionic and anionic wetting agents was used to print reactive dye on linen and viscose textiles. Comparing the samples printed with the novel printing paste to the ones that were printed using the conventional paste which contained urea, the color strength of the printings printed using the novel paste rose by about 189.78% and 168.95% for linen and viscose textiles, respectively. The wetting agent concentration, steaming temperature, and steaming duration were all determined via variable appraisals. examined the effects of these factors on the fabric's fastness, color strength, elongation, and tensile strength. Investigated how these factors impacted the fabric's color strength, fastness, elongation, and tensile strength.
