Abstract

The invention discloses an environment-friendly type yellow disperse dyestuff composition, comprising 35-71 wt% of ingredient A, 1.2-4.6 wt% of ingredient B, 5.2-13 wt% of ingredient C and 22.6-51 wt% of ingredient D, wherein the ingredient A contains one or more compounds as shown in formula (I), the ingredient B contains one or more compounds as shown in formula (II), the ingredient C is the compound as shown in formula (III) and the ingredient D contains one or more compounds as shown in formula (IV). The environment-friendly type yellow disperse dyestuff composition provided by the invention has gorgeous colors during the dyeing process, good lifting force, excellent fastness in all aspects, especially has good compatibility when blending with Disperse-Blue 2BLN and Disperse-Red 3B as well as basically consistent dyeing rate; and under the same dyeing depth, less dosage of the dye is used, dye cost is low, the pH value has a wide application range; and the environment-friendly type disperse yellow dyestuff composition is valuable and has good reproducibility.

Description

technical field [0001] The invention relates to a disperse dye composition, in particular to an environment-friendly yellow disperse dye composition, which is suitable for dyeing and printing polyester and its blended fabrics, acetate fiber and nylon. Background technique [0002] As one of the most original three primary colors, Disperse Yellow 23# has the advantages of bright colors, excellent performance and wide application. However, Disperse Yellow 23# has been listed as a banned dye by Germany and other European Union countries because it will crack under certain conditions to produce carcinogens or aromatic amines that are harmful to human body. In order to meet the needs of export, substitutes for disperse yellow 23# appeared on the market, such as disperse yellow SE-3R produced by Wenzhou Kaikai Leather Co., Ltd., although it is an environmentally friendly product, it is different from other two primary colors disperse blue 2BLN and disperse red The compatibility o...
