Description

Acid dyes chromatography aphy is complete,bright color,insolation fastness and wet process with the dye variety and fastness diffrences.And compared with the direct dyes,acidic dyes structure is simple, the lack of a long struggled with double with sexual structure and plane, so for the cellulose fibre lack direct sex, can not be used in cellulose fiber dyeing.Different types of acid dyes, due to the different molecular structure,thus their dyeing performance is different, the dyeing method is also different.
