Abstract

The invention discloses an environment-friendly yellow dye composition which consists of the following compositions in weight percentage: 7.5 to 27 percent of dye compound A shown as formula (1), 6.8 to 25 percent of dye compound B shown as formula (2), 0.01 to 0.1 percent of dye compound C shown as formula (3) and the balance being an additive. The dye composition has good compatibility, wide application range of the PH value in dyeing, high coloration amount, good level dyeing property and good fastness, has prominent advantages in fastness of sublimation and washing, and is an environment-friendly yellow dispersed dye with various superior performances.

Description

technical field [0001] The invention relates to an environment-friendly yellow disperse dye composition, which is especially suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] With the improvement of living standards in recent years, people's awareness of environmental protection has gradually increased. Therefore, like the printing and dyeing industry, higher requirements are also placed on the dyeing performance and environmental protection performance of dyes. For example, C.I.DISPYELLOW 23# has been widely used because of its superiority in bright shade, cheap price, level dyeing, covering, light fastness, acid and alkali resistance, and sweat resistance, and has become an indispensable coloring of polyester fiber. One of the basic shades. However, recent studies have found that p-aminoazobenzene in its dye structure is a carcinogen, which does not meet the German government's Oeko-Tex Standard 100 and the European Union's ...
