Embodiment 1

[0035] In the embodiment of the present invention, based on the total weight of the acid dye composition, by weight percentage, it is 13% of compound A, 2% of compound B, 1.5% of compound C, 27% of compound D, and 9% of compound E , 22% of compound F and 25.5% of dispersing agent, wherein the dispersing agent is formed by compounding sodium methylnaphthalene sulfonate formaldehyde condensate and sodium lignosulfonate in a weight percentage of 3:7, adding water and beating After mixing, disperse with a grinder, spray dry, and finally form a finished product.

Embodiment 2～9

[0037] According to the method of Example 1, according to the composition of Compound A, Compound B, Compound C, Compound D, Compound E and Compound F shown in Table 1, the acid dye composition of the embodiment of the present invention can also be obtained, which also has light fastness Fastness, sublimation fastness, soaping fastness and rubbing fastness.

[0038] Table 1

[0039]

[0040]

[0041] In Examples 1-9 of the present invention, the process conditions of the spray drying are an inlet temperature of 120-130° C., an outlet temperature of 50-60° C., and a particle size of 0.1-1 μm.

Embodiment 10

[0043] Take 0.5g of the dispersion / acidity (owf: 0.5%) prepared in Examples 1-9, add water to 15g, make it dissolve, stir well and set to volume for later use. Take 5ml of the suspension in Plot, add 20ml of buffer solution (30g of glacial acetic acid + 90g of anhydrous sodium acetate diluted with water to 10kg), add 2.5g of cloth sample and add water to 100ml, put it into an infrared proofer, and set it at 1~1.5℃ / min, heat up from room temperature to 120°C, keep warm for 40min, start to cool down at 1-1.5°C / min and cool down to 60°C. The process is all over. After completion, rinse with clean water, dehydrate and dry the cloth sample.

[0044] The color fastness test is carried out on the cloth samples obtained after dyeing in Example 10, and the dyed cloth samples obtained by dyeing with the traditional dye dispersion / acid two-bath dyeing process are compared respectively. According to the dyeing method of the above-mentioned embodiment 10, the above-mentioned According to ...

Abstract

The embodiment of the invention discloses an acidic dye composition. The acidic dye composition is prepared from five or six of a compound A as shown in a formula (I), a compound B as shown in a formula (II), a compound C as shown in a formula (III), a compound D as shown in a formula (IV), a compound E as shown in a formula (V) and a compound F as shown in a formula (VI). Through a dye product ofthe acidic dye composition provided by the embodiment of the invention, two kinds of fiber can be subjected to one-bath dyeing, the dyeing effect is good, the fiber damage is small, the production period is short, the energy consumption is small, and the production cost is low. A product obtained through the dye product provided by the embodiment of the invention is excellent in color fastness indaylight, sublimation fastness, soaping fastness and rubbing fastness.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of textile printing and dyeing, in particular to an acid dye composition and dye products thereof. Background technique [0002] In recent years, with the rapid development of chemical technology and the increasing emphasis on environmental protection, based on the many advantages of disperse dyes, especially from the perspective of saving production costs and replacing banned wool dyes, wool polyester blended fabrics use disperse dyes in one bath. The dyeing method greatly simplifies the dyeing process and has broad practical prospects for blended fabrics containing polyester or wool multi-component fibers. [0003] Wool / polyester blended fabrics combine the advantages of wool and polyester fibers to a certain extent. To achieve the ideal dyeing effect and color in the same bath dyeing of the two fibers, the dyes, auxiliaries, and process conditions used for the dyeing of the two f...
