A novel reactive printing paste urea-free for various cellulosic fabrics

A novel printing paste for linen and viscose fabrics with reactive dyes was applied attempting to tackle the issue of water contamination caused by the excessive use of urea in cellulosic fabric printing with reactive dyes. This 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 those printed with the conventional printing paste that contained urea, the K/S of the samples printed with 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, colour strength, elongation, and tensile strength. Investigated how these factors impacted the fabric's colour strength, fastness, elongation, and tensile strength.
