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 environment-friendly type composite disperse dye and a preparation method thereof. The environment-friendly type composite disperse dye is basically prepared from the following ingredients in parts by mass: 5 to 50 parts of dye monomer A which is as shown in a formula (I), 0 to 14 parts of dye monomer B which is as shown in a formula (II) and 2 to 25 parts of dye monomer C which is as shown in a formula (III). The environment-friendly type composite disperse dye provided by the invention is very suitable for dyeing and printing of polyester materials and acetate fiber materials, is good in light fastness, high in dyeing power, and bright in color light, has better covering property, better level-dyeing property, better lifting property and better absorption and purification property and is the main dye for dyeing medium to light color, and the environment-friendly type composite disperse dye not only can be used as monochrome, but also has better compatibility.

Description

[0001] (1) Technical field [0002] The invention relates to an environment-friendly composite disperse dye and its preparation method and application. The environment-friendly composite 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 t...
