Problems solved by technology

The fabrics of military uniforms often use wool fabrics. Due to the particularity of military uniforms, corresponding dyes are often required to have excellent light fastness. At present, there is a shortage of green acid dyes with high light exposure in the market, and existing products often cannot meet the demand. For the above problems, it is important to develop green acid dyes suitable for dyeing wool fabrics and having excellent light fastness

preparation example Construction

[0055] The present invention also provides a preparation method of the green acid dye according to the present invention, comprising the following steps:

[0056] After mixing the dye components, use a sand mill or a grinder to granulate them in the presence of auxiliary materials; or granulate the dye components with a sand mill or a grinder in the presence of auxiliary materials. After treatment, mixing is performed again.

[0057]Specifically, the method includes: mixing the dye monomer compounds of the green acid dye composition according to the ratio, and using a pulverizer such as a sand mill or a grinder to form particles in the presence of an auxiliary agent; In the presence of auxiliary agents, the dye monomers are separately processed into micronized particles with a pulverizer such as a sand mill or a grinder, and then mixed in the above-mentioned proportions.

[0058] The present invention also provides a use of the green acid dye according to the present inventio...

Abstract

The invention provides a green acid dye composition, a green acid dye and a preparation method and application thereof. The green acid dye composition comprises the following components: a component A as shown in a formula (I), a component B as shown in a formula (II) and one or two components C as shown in a formula (III), wherein R is hydrogen or-NHCOCH3. The green acid dye composition and the green acid dye disclosed by the invention are excellent in lifting power and good in compatibility, and have good washing fastness, rubbing fastness and excellent light fastness.

Description

technical field [0001] The invention relates to a green acid dye composition, a green acid dye, a preparation method and application thereof, and belongs to the field of dyes. Background technique [0002] Wool is mainly composed of protein. Human use of wool can be traced back to the Neolithic Age. It spread from Central Asia to the Mediterranean and other parts of the world, and became the main textile raw material in Asia and Europe. Wool fabrics have the characteristics of plump hand feeling, good warmth retention and comfortable wearing, which are deeply loved by people. The military uniform fabrics are often made of wool fabrics. Due to the particularity of military uniforms, the corresponding dyes are often required to have excellent light fastness. At present, there is a lack of high sun light green acid dyes on the market, and the existing products often cannot meet the needs. In view of the above problems, it is important to develop a green acid dye suitable for d...
