Problems solved by technology

[0004] With the continuous improvement of living standards, people have higher and higher requirements for the quality of textiles. Correspondingly, higher requirements have been put forward for the color fastness of dyed dyes. The existing market has excellent color fastness and is economical. There are not many permanent yellow disperse dyes, and yellow varieties that can be used as three primary colors are even rarer.

Embodiment 1

[0045] After 10 grams of compound of formula (I-1), 90 grams of compound of formula (II-1) and 200 grams of dispersant MF are mixed with 650 grams of water, they are ground, dispersed and dried to obtain the finished product. The dye can be provided to fabrics Yellow color with excellent fastness properties.

[0046]

Embodiment 2

[0048] After 15 grams of formula (I-1) compound, 85 grams of formula (II-2) compound and 200 grams of dispersant MF are mixed with 650 grams of water, they are ground, dispersed and dried to obtain the finished product. The dye can be provided to fabrics Yellow color with excellent fastness properties.

Abstract

The invention provides a yellow disperse dye composition. The yellow disperse dye composition comprises 5-95% by mass of component A and 5-95% by mass of component B, wherein the component A is selected from at least one of compounds shown as formula (I); the component B is selected from at least one of components shown as formula (II). The invention also provides a yellow disperse dye product. The yellow disperse dye product comprises the abovementioned yellow disperse dye composition and additives based on the weight ratio of 1: 0.2-5. The yellow disperse dye composition and the dye producthave the advantages of being high in degree of dyeing, high in improving power, outstanding in color fastness to sublimation, outstanding in crockfastness and rwashing fastness while being applicableto dyeing of hydrophobic fiber materials; the dyed yellow is full and bright.

Description

[0001] (1) Technical field [0002] The invention relates to a yellow dye composition and a dye product, in particular to a yellow disperse dye composition and a dye product suitable for printing and dyeing hydrophobic fiber materials. [0003] (2) Background technology [0004] With the continuous improvement of living standards, people have higher and higher requirements for the quality of textiles. Correspondingly, higher requirements have been put forward for the color fastness of dyed dyes. The existing market has excellent color fastness and is economical. There are not many permanent yellow disperse dyes, and yellow varieties that can be used as three primary colors are even rarer. Because the three primary color dyes can easily obtain various chromatograms, it can reduce the dye reserve of the dye application unit, facilitate dye management and reduce production costs. Therefore, it is of great industrial value to develop more yellow varieties suitable for three primary...
