1. Direct dye and cotton dyeing accelerators
When dyeing cotton with direct, sulfur,还原, and indigo dyes, sodium metabisulfite can be used as a mordant.
Direct Dye Yarn Retarder
Direct dyes are widely used in protein fibers, particularly for silk dyeing, resulting in higher color fastness compared to general acid dyes.
3. Acid Dye Retarder
During the dyeing process of animal fibers such as silk and wool with acid dyes, sulfuric acid and acetic acid are often added to promote the coloration of the pigment acid. Additionally, mordant powder is used as a retardant to slow down the dyeing.
4. Earth color protector for refining bamboo silk fabrics
During the refining process of printed or dyed silk fabrics, the dye may peel off, resulting in stains on the ground color or other processed fabrics.
