Bleaching agent "Vinipron"
Strongly binds with dyes containing sulfonyl groups, providing a powerful decolorization effect! [Samples are being given away to 10 lucky winners in a lottery]
"Vinipiron" is a bleaching agent that exhibits a powerful decolorizing effect on direct dyes, reactive dyes, and sulfur dyes. This product is a water-soluble resin, chemically distinct from surfactants. It strongly binds with dyes containing sulfonic groups, such as direct dyes, reactive dyes, and sulfur dyes, and its affinity is stronger than that between cellulose and the dye, causing the dye to detach from the fiber and dissolve in water. Re-adhesion of the dissolved dye to the fiber does not occur. 【Features】 ■ Water-soluble resin ■ Strongly binds with dyes containing sulfonic groups ■ Dyes detach from the fiber and dissolve in water ■ Re-adhesion of dissolved dyes to the fiber does not occur *For more details, please refer to the PDF document or feel free to contact us. ★ We are currently giving away samples to 10 lucky individuals selected from those who download the materials!
