Embodiment Construction

[0020] The present invention is further illustrated below by means of examples, but the present invention is not limited to the scope of the examples. For the experimental methods that do not specify specific conditions in the following examples, select according to conventional methods and conditions, or according to the product instructions.

[0021] In the embodiment of the present invention,

[0022] Dye monomer A is C.I. reactive black 5 (commercially available conventional product);

[0023] Dye monomer B is Ciba Reactive Brown P-6R;

[0024] Dye monomer C is Ciba Reactive Yellow P-2RN.

[0025] Example Mix the dye monomer A, dye monomer B, dye monomer C and co-solvent, and adopt the commonly used monomer powder blending method in this industry. The powder blending needs to ensure that the lower part of the material returns to the upper part. 3 times, with a total mixing time of 3 hours. For the above mixing methods, samples should be taken from the top, middle and bo...

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 invention relates to a black dye, a dye composition and applications thereof. Background technique [0002] At present, the reactive black dyes used for viscose fiber 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 dyes compounded with black 39 and brown 11. 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 getting higher and higher, so that the requirements for the performance of reactive dyes used in textile dyeing are becoming increasingly stringent. Reactive dyes must not only have excellent color fastness and dyeing performance, but also meet environmental protection requirements. Contents of the invention [0004] The present invention provides a black dye, a dy...
