Overview of Discharge Printing Techniques on Denim Fabric

Abstract

ischarge printing: is a type of printing in which the ink is applied to a previously colored cloth, often known as the 'ground' shade. The dyes used for the ground shade must be carefully chosen such that when a proper print paste is applied, the dyed cloth is permanently decolored locally, resulting in a 'white' discharge patterning look. Discharge printing produces vivid, opaque graphics on dark textiles while maintaining a delicate feel. The patterns on the cloth are created by the chemical degradation of the original dye in the printed sections in the discharge technique. With these factors in mind, the current study attempted to optimize the discharge printing recipe by adjusting the dye and discharging agent concentrations. of dye and discharging agent, for denim cotton fabric dyed with eco-friendly reactive dye and to assess the physical and color fastness properties of printed samples.

Various Printing Techniques of Intelligent Lyocell Fabric to Enhancing its Performance Properties

“…Direct, discharge, and resist printing are the three types of printing. [28][29][30][31][32][33][34] Direct printing involves printing colored pastes directly on the fabric. The fabric is first dyed with a background color for discharge printing, which is then removed by reagents, or reducing agents, conveyed in a print paste.…”

Various Printing Techniques of Cotton/Polyester Blended Fabrics to Enhancing its Performance Properties

“…The colored discharge is obtained by adding, to the paste, some dyes stable to the discha1gi1Eg agent fixed places where the ground dye is destroyed. [4,62,63]…”

Denim Manufacturing and Washing as a Fashioned Garments

“…The adoption of genetically modified cotton is another option for reducing pesticide consumption. [7] Cotton can also be blended with lycra, polyester, lyocell, wool, flax, hemp, and other materials to create unique denim styles. Even though many of these fibers are now being used in denim, it is quite impossible that they will ever totally replace cotton.…”
