Abstract

The invention provides a low-temperature and environmental-friendly disperse yellow dye composition, mainly comprising 20-80 parts by weight of component A, 0-80 parts by weight of component B and / or 0-80 parts by weight of component C, wherein the component A is a dye shown in the formula (I), the component B is a mixture of dyes shown in the formula (II) and the formula (III), and the component C is a dye shown in the formula (IV); when used for dyeing, the low-temperature and environment-friendly disperse yellow dye composition provided by the invention is excellent in fastness, high in dyeing speed, good in leveling property, good in color matching compatibility with low-temperature (disperse red 3B and disperse blue 2BLN) dyes, good in synchronous leveling property with blending products and good in color rendering.

Description

(1) Technical field [0001] The invention relates to a dye composition, in particular to a low-temperature environment-friendly disperse yellow dye composition suitable for dyeing polyester fibers or fabrics. (2) Background technology [0002] With the continuous strengthening of people's awareness of environmental protection, the European Union has also promulgated a series of laws and regulations on textile eco-environmental protection issues. Disperse Yellow 23 has been listed as a banned dye due to its cleavage under certain conditions and the production of suspected carcinogenic substances. However, as one of the three primary colors at low temperature, Disperse Yellow 23 is often mixed with Disperse Blue 2BLN and Disperse Red 3B, and its usage is relatively large. Many products that replace Disperse Yellow 23 have also appeared on the market, such as Chinese patents CN1667051A and CN101760045A. However, the level dyeing property of the substitute product and the synch...
