Abstract

The invention refers to a kind of low-temperature green disperse dyes and is especially adaptable to the printing and dyeing of polyester material and vinegar acyl material. The low-temperature green disperse dyes in the invention is composed of the following components: in amounts of weight, between 15% and 50% of chromatid A, between 3% and 25% of chromatid B and the rest of the auxiliary agent. The low-temperature green disperse dyes in the invention has strong fastness, high tintage, vivid color, good level-dyeing property and building up properties, can be used as homochromy products, also can mix with blue of 2BLN and red of 3B and has excellent compatibility.

Description

(1) Technical field [0001] The invention relates to a low-temperature environment-friendly disperse dye, which is especially suitable for printing and dyeing polyester materials and acetate fiber materials. (2) Technical background [0002] There are many types of yellow disperse dyes used for dyeing polyester materials and cellulose acetate materials, among which C.I. Disperse Yellow 23 (old yellow RGFL) is used in a large amount, but it will be cracked under certain conditions to produce suspected carcinogenic substances, or Aromatic amines, which are harmful to humans, have been listed as banned disperse dyes by Germany and other EU countries. Therefore, at present, manufacturers urgently need to find a variety that can effectively replace the old yellow RGFL, and the yellow light must be close to it, and the performance must also be similar to it. The dyes form an effective compatibility, on the other hand, they must be environmentally friendly and can meet the needs of...
