Problems solved by technology

[0002] 1-Amino-4-hydroxyl-2-phenoxy-9,10-anthraquinone is an important bright red dye, and its typical commercially available products are Disperse Red 3B and Disperse Red FB, but these products are harmful to dyeing solutions and cloth surfaces For example, the pH value of the dyeing medium must be controlled at weak acidity (4.0-6.5). When the dyeing medium is weakly alkaline or the fibers contain alkaline substances, it is easy to appear blue on the cloth surface. spots, while the dye depth decreases, resulting in an increase in the color of the wastewater
In addition, after the dye is solvated into purple, it still shows bright red after high-temperature dyeing. The existing technology needs to achieve the effect of purple dyeing through color matching of dyes, and there are obvious problems.

Embodiment 1

[0045] Mix 10.0g of 1-amino-4-hydroxy-2-phenoxy-9,10-anthraquinone, 1.5g of dispersant CNF, 2.0g of 1815, 0.2g of sodium hydroxide and 75.0g of water in percentage by mass, and grind thoroughly. Then add 0.2g of ethanol, 0.6g of sodium polyacrylate, 4.5g of water-soluble polyester, 0.3g of water-soluble polyether and 5.7g of water, and stir thoroughly to obtain a liquid purple-red disperse dye A.

[0046] In the intermittent high-temperature dyeing machine, add 100Kg of polyester fabric (adjust the pH value of the solution to 10.0), 4Kg of liquid purple-red disperse dye A and 800Kg of water, raise the temperature to 120°C, and keep it at this temperature for 30 minutes. After dyeing, use 50 ℃ hot water washing, made bright purple polyester fabric.

Embodiment 2

[0048] Mix 20.0g of 1-amino-4hydroxy-2-phenoxy-9,10-anthraquinone, 3.8g of dispersant CNF, 2.0g of 1815, 0.5g of sodium hydroxide and 65.0g of water in percentage by mass, and grind thoroughly, Then add 0.3g of ethanol, 0.3g of sodium polyacrylate, 5.0g of water-soluble polyester, 0.4g of water-soluble polyether and 2.7g of water, and stir thoroughly to obtain liquid purple-red disperse dye B.

[0049] In the intermittent high-temperature dyeing machine, add 100Kg of polyester fabric (adjust the pH value of the solution to 9.0), 2Kg of liquid purple-red disperse dye B and 800Kg of water, raise the temperature to 120 ° C, and keep it at this temperature for 30 minutes. After dyeing, use 50 ℃ hot water washing, made bright purple polyester fabric.

Embodiment 3

[0051] Mix 10.0g of 1-amino-4-hydroxy-2-phenoxy-9,10-anthraquinone, 3.8g of dispersant CNF, 1.0g of 1815, 0.5g of borax and 75.0g of water in percentage by mass, grind thoroughly, and then add 0.3g of ethanol, 0.3g of sodium polyacrylate, 5.0g of water-soluble polyester, 0.4g of water-soluble polyether and 3.7g of water were thoroughly stirred to obtain liquid purple-red disperse dye C.

[0052] In the intermittent high-temperature dyeing machine, add 100Kg of polyester fabric (adjust the pH value of the solution to 8.0), 4Kg of liquid purple-red disperse dye C and 800Kg of water, raise the temperature to 135 ° C, and keep it at this temperature for 30 minutes. After dyeing, use 50 ℃ hot water washing, made bright purple polyester fabric.

Abstract

The invention discloses an aubergine liquid disperse dye as well as a preparation method and application of the dye. The aubergine liquid disperse dye is prepared from 1-amino-4-hydroxy-9,10 anthraquinone and CNF, 1815, alkali, ethanol, sodium polyacrylate, water soluble polyester and water soluble polyether; by adding water soluble polyester and polyether as well as sodium polyacrylate, an aubergine dyeing product is obtained for the first time, thus solving the problem that aubergine needs to be formed by color matching of the prior art, and widening the hue of 1-amino-4-hydroxy-9,10 anthraquinone dye.
