Embodiment 1

[0039] In the embodiment of the present invention, based on the total mass of the acid dye composition used for dyeing in the same bath, calculated by weight percentage, the acid dye composition includes: 16% of compound A, 2% of compound B, 20 % compound C, 6% compound D, 9% compound E, 8% compound F and 39% dispersant. Among them, the dispersant is formed by compounding sodium methylnaphthalenesulfonate formaldehyde condensate and sodium lignosulfonate in a weight percentage of 3:7. After adding water and beating and mixing, disperse with a grinder, spray dry, and the process conditions for spray drying are: : The inlet temperature is 125°C, the outlet temperature is 58°C, and the finished product with a particle size of 0.7μm is obtained after drying.

Embodiment 2-9

[0053] According to the method described in Example 1, the difference is that each component shown in Table 1 and the content of each component are mixed, and the acid dye composition for same-bath dyeing of the embodiment of the present invention can also be obtained. The dye composition enables two kinds of fibers to be dyed in the same bath, has good dyeing effect, and has excellent light fastness, sublimation fastness, soaping fastness and rubbing fastness.

Embodiment 10

[0064] Take 0.5g of the dispersion / acidity (owf: 0.5%) prepared in Example 1, add water to 15g, make it dissolve, stir well and set to volume for later use.

[0065] 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 from room temperature to 120°C, keep warm for 40 minutes, 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.

Abstract

The embodiment of the invention discloses an acid dye composite for one bath dyeing. The composite comprises five or six of a compound A shown in the formula (I), a compound B shown in the formula (II), a compound C shown in the formula (III), a compound D shown in the formula (IV), a compound E shown in the formula (V) and a compound F shown in the formula (VI). The product prepared through the acid dye composite is bright in color and luster, has excellent sun-proof fastness, sublimation fastness, soaping fastness and friction fastness, causes small damage to fibers and is short in production period, small in energy consumption and low in production cost, the dyeing process is greatly shortened, the energy can be saved, the cost is reduced, the efficiency is improved, and sewage discharging is reduced.

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 for one-bath dyeing. 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 of multi-component fiber blended fabrics containing polyester and wool. [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 fibers are different. They should confli...
