Embodiment 1

[0093] The former dye A1 shown in formula (I) gets 2 grams, A18 gets 8 grams, the former dye B1 shown in formula (II) gets 5 grams, B30 gets 7.5 grams, the former dye C6 shown in formula (III) gets 12.5 grams, the former dyestuff D3 shown in formula (IV) gets 15 grams, then adds 67 grams of dispersant MF, 8 grams of sodium lignin sulfonate, 153 grams of water and carries out dispersion treatment together with sand mill, then spray drying, to obtain final product Dye compositions of the invention.

Embodiment 2～27

[0095] According to the preparation method of Example 1, according to the data shown in Table 5, at least one dye A, at least one dye B, at least one dye C, at least one dye D and dispersant MF, sodium lignosulfonate Blending with water, sand milling to disperse, and spray drying to obtain finished disperse dyes. Among them, the structural formulas defined by the substituents of the dyes A, B, C, and D are shown in Tables 1 to 4.

[0107] Take 2.5 grams of the disperse dyes prepared in Examples 1-27 and disperse them in 500 milliliters of water to form a dye suspension, draw 20 milliliters and mix them with 80 milliliters of water, adjust the pH of the dyeing bath to 4-5 with acetic acid, and heat up to 70 °C At the same time, put 5 grams of polyester fiber cloth for dyeing, heat up from 70°C to 130°C within 30 minutes, keep warm for 50 minutes, cool to below 90°C, drain and wash. Then put the cloth sample into 100 milliliters of reduction cleaning solution containing 1 gram per liter of caustic soda and 3 grams per liter of sodium hydrosulfite to clean at 80° C. for 20 minutes. According to the national standard GB / T2397-2003, the lifting power of the disperse dyes prepared in Examples 1 to 27 was measured, and the national standard GB / T3921-2008, GB / T3920-2008, GB / T8427-2008, GB / T5718-1997 were used to test their resistance Washing, rubbing, light fastness and sublimation color fastness. The test resu...

Abstract

The invention discloses a navy blue or black disperse dye composition. The navy blue or black disperse dye composition contains one or more of dye A shown as formula (I), one or more of dye B shown as formula (II), one or more of dye C shown as formula (III) and one or more of dye D shown as formula (IV). The navy blue or black disperse dye composition provided by the invention has the characteristics of high chromogenic intensity, excellent lifting power and excellent color fastness when applied in textile dyeing, can reach the dyeing depth consistent with conventional fastness dyes, and does not contain 24 kinds of forbidden aromatic amines or forbidden carcinogenic and allergenic dyes, etc. and meets the requirements of environmental protection. (formula (I), formula (II), formula (III), formula (IV)).

Description

technical field [0001] The invention relates to the field of fine chemicals, in particular to a navy blue or black disperse dye disperse dye composition. Background technique [0002] Monoazo-type disperse dyes occupy an important position in the dyeing and printing of hydrophobic fibers, especially polyester fiber products, because of their simple synthesis process, low price, complete chromatogram, good application and fastness performance, and are widely used. Disperse dyes. [0003] In recent years, with the enhancement of people's awareness of environmental protection and health, consumers have higher and higher requirements for the color fastness level and ecological performance of textiles. For disperse dyes, products with conventional fastness requirements are still widely used in the market, such as disperse navy blue EXN-SF and disperse navy blue EXN-SF, which are generally composed of C.I. disperse blue 291:1, C.I. Black EXN-SF, these dyes are still lacking in w...
