Application
In the printing and dyeing industry, the state of dyes is crucial for their effective bonding with fabrics. Some dyes can firmly attach to fabrics only when they are in a reduced condition. Herein lies the significance of sodium thiosulfate. Due to its reducing characteristic, sodium thiosulfate has the ability to transform some oxidized dyes into a reducible form suitable for the dyeing process.
It is employed in the dechlorination stage following the bleaching of paper. By doing so, it helps to stabilize the whiteness of the paper and safeguards paper fibers from the harm caused by residual substances, thus effectively extending the time that the paper can be preserved.
