Embodiment 1

[0024] Mix 29 grams of dye monomer A, 92 grams of dye monomer B, 158 grams of dye monomer C, and 721 grams of sodium lignosulfonate, add 1500 grams of water, grind and disperse with a grinder, and then spray dry. About 1000 grams of finished product were obtained.

[0025] The above-mentioned sodium lignosulfonate can be replaced by an equivalent amount of naphthalenesulfonic acid formaldehyde condensate (NNO) or methylnaphthalenesulfonic acid formaldehyde condensate (MF) or benzylnaphthalenesulfonic acid formaldehyde condensate (CNF). Sodium lignosulfonate, naphthalenesulfonate formaldehyde condensate (NNO), methylnaphthalenesulfonate formaldehyde condensate (MF), benzylnaphthalenesulfonate formaldehyde condensate (CNF) any two or three or four mixture.

Embodiment 2

[0027] Mix 300 grams of dye monomer A, 9 grams of dye monomer B, 150 grams of dye monomer C, and 721 grams of sodium lignosulfonate, add 1500 grams of water, grind and disperse with a grinder, and then spray dry. About 1000 grams of finished product were obtained.

[0028] The above-mentioned sodium lignosulfonate can be replaced by an equivalent amount of naphthalenesulfonic acid formaldehyde condensate (NNO) or methylnaphthalenesulfonic acid formaldehyde condensate (MF) or benzylnaphthalenesulfonic acid formaldehyde condensate (CNF). Sodium lignosulfonate, naphthalenesulfonate formaldehyde condensate (NNO), methylnaphthalenesulfonate formaldehyde condensate (MF), benzylnaphthalenesulfonate formaldehyde condensate (CNF) any two or three or four mixture.

Abstract

The invention discloses a composite type dispersion dye essentially comprising the following constituents: colorant monomer A 2.9-30 wt%, colorant monomer B 0.9-9.2 wt%, colorant monomer C 1.5-15.8%, and balancing auxiliary agents.

Description

technical field [0001] The invention relates to a composite environment-friendly disperse dye, which is especially suitable for printing and dyeing polyester materials and acetate fiber materials. technical background [0002] When polyester materials and acetate materials are dyed gray, most of them use low-temperature ternary colors C.I. Disperse Blue 56 (Disperse Blue 2BLN), C.I. Disperse Red 60 (Disperse Red 3B), and C.I. Disperse Yellow 23 (Disperse Yellow RGFL), but due to the Under certain conditions, it will crack to produce suspected carcinogenic substances, or aromatic amines that are harmful to the human body have been listed as banned disperse dyes by Germany and other EU countries, and the gray series of disperse dyes made of the above-mentioned low-temperature old ternary colors are also available. There are disadvantages such as low dyeing rate, compatibility and compatibility that cannot meet the requirements, so it is still difficult to control the cylinder ...
