2-Naphthalenesulfonic acid, 6-hydroxy-5-[2-[4-[2-[4-(phenylamino)-3-sulfophenyl]diazenyl]-1-naphthalenyl]diazenyl]-, sodium salt (1:2) Use and Manufacturing
Using 2-anilino-5-aminobenzenesulfonic acid, 1-naphthylamine and Chevroic acid (2-naphthol-6-sulfonic acid) as raw materials, first diazonium 2-anilino-5-aminobenzenesulfonic acid And then coupling with 1-naphthylamine, and then diazotizing the coupling product and coupling with Chevroic acid to obtain the product. The finished product is obtained by salting out, filtering, drying and crushing.
Weak acid black VL is suitable for dyeing wool, nylon, silk and wool blended fabrics, suitable for dyeing loose hair, tops, skeins, and most suitable for dyeing felt hats, which are black. When used in the same bath dyeing of wool and other fibers, the wool is black, the nylon is dark blue, the silk is lighter in color, and the cellulose fiber and acetate fiber are stained. Can also be used for leather coloring.
