Application
During the hair - removal stage of leather processing, sodium thiosulfate plays a crucial role. It has the ability to break the disulfide bonds (-S - S -) present in the hair. When these bonds are disrupted, the connection between the hair and the leather is weakened. Consequently, the hair can be effortlessly removed from the surface of the leather, making the hair - removal process in leather production much more convenient.
In the printing and dyeing industry, the state of dyes is of utmost significance for their effective attachment to fabrics. Some particular dyes are only capable of establishing a firm bond with fabrics when they are in a reduced state. This is exactly where sodium thiosulfate comes into play. Because of its reducing nature, sodium thiosulfate can transform certain oxidized dyes into a reducible condition that is suitable for the dyeing process.
