Generation of redox systems by fiber materials on the reduction of vat and sulfur dyes: Research and practical implementation

Abstract

An essential part of the processes of refinement of textile materials from natural cellulose fiber is based on redox reactions of the components of process solutions both with admixtures in the fiber and with cellulose. The reducing agents involved in these processes are used in the alkaline treatment of textile materials as antioxidants whose function is to prevent oxidative destruction of cellulose; reducing agents are also introduced into vat or sulfur dye compositions to convert these insoluble dyes into soluble leuco compounds.
