Problems solved by technology

Patent CN1580133A (a low-temperature environment-friendly disperse dye) discloses a low-temperature type yellow dye composition, but after gradual use by manufacturers, it is found that the golden sublimation fastness is poor, the light fastness is not ideal, and it is not resistant to alkali. Under alkaline conditions, the color deviation is relatively large, and the red light is obvious
Patent CN103740135A (a low-temperature environment-friendly disperse yellow dye composition) discloses a low-temperature yellow dye composition. In component A, acetoxyethyl is introduced, and in component C, disperse yellow with a pyridone structure is introduced. This makes the alkali resistance of the composition greatly limited

Embodiment 1～20

[0036] According to the data shown in Table 1, dye component A, dye component B, dye component C and auxiliary agents (dispersant MF, diffusing agent CNF, sodium lignosulfonate), after adding water and blending, use a sand mill Grind and disperse, followed by spray drying.

[0037] Wherein, component A can adopt commercially available product, the dispersion yellow 54# that Zhejiang Shanyu Technology Co., Ltd. produces;

[0038] Component B can use Disperse Orange 25# produced by Zhejiang Shanyu Science and Technology Co., Ltd.;

[0039] Component C can use Disperse Orange 29# produced by Zhejiang Shuangguan Dye Co., Ltd.;

Embodiment 19

[0048] The yellow disperse dye composition that above-mentioned embodiment is made carries out performance test, and test method is as follows:

[0049] According to the method similar to GB / T2394-2003, each take 0.5 grams of the disperse dyes prepared in Examples 1 to 18, Comparative Examples 1 to 3, and the comparative samples prepared in Comparative Examples 1 to 3, and prepare them with water so that the concentration is 0.5g / 500ml of disperse dye suspension, mix 20ml with 80ml of water, adjust the pH value of the dyeing bath to 5 with acetic acid / sodium acetate, then raise the temperature to 60°C, and put 2g of polyester fiber fabric respectively, press figure 1 Carry out high temperature and high pressure dyeing, cool to 80 ℃ and sample.

[0050] Observe the shade of the cloth sample and adopt GB / T2397-2012 (lifting force), GB / T8427-2008 (light fastness), GB / T3921-2008 (washing fastness), GB / T3920-2008 (rubbing fastness), GB / T5718-1997 (sublimation fastness) measures i...

Abstract

The invention discloses an environmental-friendly composite dispersing yellow dye composition and a dye. The composition comprises, by weight, 10%-65% of a component A, 0%-35% of a component B, 0.5%-35% of a component C and the balanced 20%-85% of an auxiliary. The composition has the advantages that each colour fastness of the composition is excellent, the chromogenic power is high, the color isbrilliance, the leveling property and promotion are good, the composition can be used as a single-color species and can be used by matching with dispersing dyes of 2BLN blue, 3B red, SE-GFL ruby, SE-2R blue and the like, and the compatibility is excellent.

Description

technical field [0001] The invention relates to the technical field of dye preparation, in particular to an environment-friendly compound disperse yellow dye composition used for printing and dyeing polyester materials and acetate materials and a dye prepared from the composition. Background technique [0002] With the rapid development of synthetic fibers, especially polyester fibers, disperse dyes, as special dyes for polyester fibers, have gradually become one of the fastest-growing dyes. In order to improve the application performance of disperse dyes and meet the requirements of environmental protection, while developing new varieties of disperse dyes, its commercial processing technology and compounding technology have also become the focus of research. [0003] There are many types of yellow dyes used for disperse dyeing. Previously, disperse yellow 23 (simple structure, easy to obtain raw materials, easy synthesis, and cheap price) was used in a large market as a sha...
