How to improve the color fastness of reactive dyesReactive dyes dye cellulose fibers to form chemical bonds with the fibers in the form of covalent bonds. Therefore, theoretically, the covalent bond between the dye and the fiber can give the dyed fabric excellent dye fastness. But in fact, its dyed Read More

Level dyeing problem of reactive dyesWhen reactive dyes are dyed, special bath softeners have been used to prevent rope creases or to promote dye penetration.Since reactive dyes are water-soluble, anionic levelling agents are generally not used. However, some reactive dyes have low solubility in alk Read More
