Problems solved by technology

For example, the disperse yellow E-GL produced by Zhegong Longsheng Co., Ltd. and the disperse yellow ERGFL produced by Zhejiang Shanyu Company are environmentally friendly products, but their compatibility with other two primary colors disperse blue 2BLN and disperse red 3B is poor , mainly manifested in the fact that it will run yellow when it is set after dyeing, which is easy to cause color runaway, which proves that the sublimation fastness of the above-mentioned dyes is poor

Embodiment 1

[0027] After mixing 40 grams of formula (I) compound, 10 grams of formula (II-1) compound, 1 gram of formula (II-2) compound, 53 grams of dispersant MF, and adding 160 grams of water, grind and disperse, spray dry, A finished product is obtained which provides a yellow shade to the fabric.

Embodiment 2

[0029] The disperse dye of embodiment 2-17 is prepared according to the method described in embodiment 1, difference is to adopt the weight ratio of component A, component B in the table below and auxiliary agent, add water and make slurry after blending, control the density of slurry The solid content is preferably 35-45%. Grinding and dispersing, and spray drying to obtain a finished product can provide fabrics with uniform yellow hue and good fastness performance. The auxiliaries in the following table are represented by abbreviations, respectively: dispersant MF is methylnaphthalenesulfonic acid formaldehyde condensate, diffusing agent NNO is naphthalenesulfonic acid formaldehyde condensate, diffusing agent CNF is benzylnaphthalenesulfonic acid formaldehyde condensate, Lignin 85A and 83A are different specifications of sodium lignosulfonate.

Abstract

The invention belongs to the technical field of dyes and particularly relates to a disperse yellow dye composition, which comprises a component A, a component B and an auxiliary agent, the component Ais a compound represented by a formula (I), the component B is selected from one or more of compounds represented by a formula (II) and X is selected from hydrogen and cyanoalkyl, and the invention also provides a preparation method and an application of the disperse yellow dye composition. The disperse yellow dye composition provided by the invention overcomes the defects of alkali resistance and sublimation fastness of the existing substitute disperse yellow 23 # product, has the advantages of bright colored light, good compatibility and wider pH value application range, has obvious advantages of light fastness and sublimation fastness, and is low in price, economical and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of dyes, and in particular relates to a disperse yellow dye composition, a preparation method and an application thereof. Background technique [0002] Traditionally, Disperse Yellow 23# has been widely used. Although Disperse Yellow 23# contains p-aminoazobenzene and does not meet the OKO-TEX100 standard, although the price is affordable and the performance is excellent, various companies have launched many alternative products one after another. For example, the disperse yellow E-GL produced by Zhegong Longsheng Co., Ltd. and the disperse yellow ERGFL produced by Zhejiang Shanyu Company are environmentally friendly products, but their compatibility with other two primary colors disperse blue 2BLN and disperse red 3B is poor , which is mainly manifested in the fact that it will run yellow when it is set after dyeing, which is easy to cause color runaway, which proves that the sublimation fastness of the abo...
