Weak acid dye

Abstract

The invention discloses weak acid dye, which is prepared from the following ingredients in parts by weight: 14 to 16 parts of methyl blue, 23 to 26 parts of methyl green, 31 to 33 parts of basic fuchsin, 10 to 16 parts of sodium citrate, 13 to 18 parts of iron ions, 2 to 5 parts of alginic acid, 10 to 12 parts of bean sprout powder, 17 to 20 parts of fish meal, 11 to 18 parts of seed liquid, 21 to24 parts of arrowroot flour and 9 to10 parts of herba houttuyniae. The weak acid dye has the advantages that the weak acid dye adopting the technical scheme is natural and does not have foreign odor;the coloring speed is high; the color fading cannot easily occur.
