Problems solved by technology

[0005] At present, some golden disperse dyes that replace C.I. Disperse Yellow 23 appearing on the market, after being gradually put into practical use by printing and dyeing manufacturers, it is found that they have poor compatibility with Disperse Blue 2BLN, Disperse Red 3B, etc. in the color matching process. Overflow dyeing is prone to color blooming, so printing and dyeing manufacturers urgently need an effective substitute for the old yellow RGFL

Abstract

The invention provides an environmental-friendly combined disperse dye and a preparation method thereof. The environmental-friendly combined disperse dye is basically composed of the following components in parts by mass: 0.5-75 parts of monomeric dyes A shown as a formula (I) and 0.5-75 parts of monomeric dyes B shown as a formula (II). The environmental-friendly combined disperse dye disclosed by the invention is very applicable to dyeing and printing of polyester materials and acetate fiber materials, is excellent in light fastness, high in coloring property and bright in colored light, has high covering power, leveling property, lifting property and purification performance, is a main light-colored dye in dyestuff, can realize monogenetic use and has high blending performance. The structural formula is as shown in the specification.

Description

[0001] (1) Technical field [0002] The invention relates to an environment-friendly combined disperse dye and its preparation method and application. The environment-friendly combined disperse dye is especially suitable for dyeing and printing polyester materials and acetate materials. [0003] (2) Background technology [0004] Judging from the current situation of textile fabrics, the proportion of fabrics made of a variety of fibers is increasing year by year, such as some domestic high-end fabrics, including polyester blended fabrics. The disperse dyes currently available on the market cannot well meet the printing and dyeing needs of such textiles. There are many kinds of yellow disperse dyes used for dyeing polyester materials and acetate materials, such as C.I. Disperse Yellow 23 (old yellow RGFL) is used in a relatively large amount, but due to the instability of the disazo molecular structure of the dye under certain conditions Aromatic amines that can be cracked to ...
