Embodiment 1—7

[0053] According to the data provided in Table 1, after mixing the dye monomer A, dye monomer B, dye monomer C, dye monomer D, dye monomer E and auxiliary agents, grind and disperse them with a grinder, and then spray dry them. Produce disperse dyes.

Embodiment 7

[0057] Take 1 gram of the disperse dyes prepared in Examples 1-6 and disperse them in 1000 milliliters of water, absorb 20 milliliters and mix them with 60 milliliters of water, adjust the pH of the dyeing bath to 5 with acetic acid, heat up to 65 ° C, and put 2 Dye the polyester / cotton cloth in 4 minutes, heat up from 65°C to 120°C within 4 minutes, keep it warm for 50 minutes, and start sampling when it cools down to 80°C. The national standards GB / T3921-1997, GB / T3920-1997, GB / T8427-1998, GB / T5718-1997 were used to test the color fastness to washing, rubbing, light and sublimation respectively. The test results are shown in Table 2.

Abstract

The invention discloses a disperse dye. The disperse dye is composed of, by weight, 28 to 30% of a dye monomer A, 22 to 25% of a dye monomer B, 12 to 15% of a dye monomer C, 10 to 13% of a dye monomer D, 8 to 10% of a dye monomer E, and an auxiliary agent being the balance. After dyeing by the disperse dye, a textile fabric has improved washability, friction resistance and color fastness to light and sublimation and acquires ideal durability.

Description

technical field [0001] The present invention relates to a dye mixture. Background technique [0002] Disperse dyes are a class of non-ionic dyes with low water solubility. Disperse dyes were first used in the dyeing of acetate fibers, known as acetate dyes. With the development of synthetic fibers, nylon and polyester have appeared one after another, especially polyester, because of its high alignment, less fiber voids, and strong hydrophobicity. The fiber needs to be swollen under high temperature and hot melting, so that the dye can enter the fiber and be dyed. With the development of synthetic fibers, people also put forward new requirements for dyes, that is, dyes with better hydrophobicity and dispersibility are required. At present, dyes can basically meet the requirements of hydrophobicity and dispersibility, but in terms of durability, the existing disperse dyes cannot meet people's requirements.
