Embodiment Construction

[0020] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the described examples. The experimental methods that do not specify specific conditions in the following examples are selected according to conventional methods and conditions, or according to the product description.

[0021] In the embodiment of the present invention,

[0022] The dye monomer A is C.I. Reactive Black 5 (commercially available conventional product);

[0023] Dye monomer B is Ciba refined reactive brown P-6R;

[0024] The dye monomer C is Ciba refined active yellow P-2RN.

[0025] Example The dye monomer A, dye monomer B, dye monomer C and co-solvent are mixed, and the monomer powder mixing method commonly used in the industry is used. The powder mixing needs to ensure that the lower mouth material returns to the upper mouth. 3 times, the total mixing time is 3 hours, the above mixing methods are sampled from the top, middle ...

Abstract

The invention discloses a black dye, a dye composition, and an application of the dye. The dye composition comprises, by mass, 50-70% of a dye monomer A represented by formula (1), 20-30% of a dye monomer B represented by formula (2) and 8-22% of a dye monomer C represented by formula (3); and the total percentage of the dye composition is 100%. The dye prepared from the de composition is a composite dye, has excellent dye fastness and dye performances, guarantees the blackness, has good hand feeling, and is especially suitable for dyeing cellulose materials.

Description

technical field [0001] The present invention relates to a black dye, a dye composition and its application. Background technique [0002] At present, the reactive black dyes used for viscose printing on the market are mainly dual reactive black dyes compounded with reactive black 5# and reactive orange 133#, and monochloro-s-triazine P-type reactive compound compounded with black 39 and brown 11. For dyes, the former has excellent blackness but poor hand feeling, and the latter has good hand feeling but poor blackness. [0003] With the improvement of living standards, people's requirements for textile products are also getting higher and higher, so the requirements for various properties of reactive dyes used in textile dyeing are becoming more and more stringent. Reactive dyes must not only have excellent color fastness and dyeing properties, but also meet environmental protection requirements. SUMMARY OF THE INVENTION [0004] The present invention provides a black dy...
