Dyeing auxiliaries, their manufacturing methods, and the dyeing processes in which they are applied

Abstract

This invention provides a dyeing auxiliary agent, its manufacturing method, and the dyeing process in which it is applied. Using animal glue, tartaric acid, epichlorohydrin, and sodium bisulfite as raw materials, a surfactant derived from hydrolyzed animal glue is synthesized through reaction. The auxiliary agent utilizes its agglomeration properties to capture and carry dyes from dyeing and finishing wastewater into cellulosic fabrics, thereby increasing the dyeing rate of the fabric and reducing the dye residue rate in the subsequent wastewater.
