Application
In the leather processing hair - removal phase, sodium thiosulfate is of great significance. It is capable of cleaving the disulfide bonds (-S - S -) existing in the hair. Once these bonds are broken, the adhesion between the hair and the leather weakens. As a result, the hair can be easily detached from the leather surface, which greatly facilitates the hair - removal process in leather manufacturing.
In the printing and dyeing industry, the condition of dyes is of vital importance for their successful bonding with fabrics. There are specific dyes that can form a strong connection with fabrics only when they are in a reduced state. This is precisely where sodium thiosulfate becomes essential. Owing to its reducing property, sodium thiosulfate is able to convert certain oxidized dyes into a reducible state that is appropriate for the dyeing procedure.
