Abstract

The invention discloses an environment-friendly type composite disperse green dye composition and a dye. The environment-friendly type composite disperse green dye composition comprises the following components in mass fraction: 25-70% of one or more components A with structures as shown in formula (I), 20-55% of one or more components B with structures as shown in formula (II), 0-40% of one or more components C with structures as shown in formula (III) and 0-20% of one or more components D with structures as shown in formula (IV). The disperse green dye prepared from the disperse green dye composition disclosed by the invention is high in lifting power, good in deep dyeing property and excellent in light fastness, fastness to rubbing, fastness to sublimation and the like. The dye is suitable for dyeing and printing of dacron and blended fabrics thereof, and is an economical and environment-friendly disperse green dye with high washing fastness.

Description

technical field [0001] The invention relates to the technical field of dye preparation, in particular to an environment-friendly composite disperse green dye composition suitable for dyeing and printing polyester and its blended fabrics and the dye prepared from the composition. Background technique [0002] With the rapid development of synthetic fibers, especially polyester fibers, disperse dyes, as special dyes for polyester fibers, have gradually become one of the fastest-growing dyes. In order to improve the application performance of disperse dyes and meet the requirements of environmental protection, while developing new varieties of disperse dyes, its commercial processing technology and compounding technology have also become the focus of research. [0003] There is a lack of pure green dyes in disperse dyes, so most of them are color matching. At present, the common green disperse dyes in the market are mainly disperse SE-4B, or disperse Brilliant Blue S-BG and di...
