Problems solved by technology

[0010] At present, there are many dye compositions mixed in the market in our country, and the quality is good, but the content of impurities, salt and heavy metals in the disperse dyes existing in the domestic market is relatively high, and the composition is complex, and the melting point is also low. Under the same conditions, it will inevitably affect the dyeing rate, shade and dyeing fastness of the dye
And the contamination to other fibers is relatively serious, and the sublimation fastness, thermal migration fastness and wet rubbing fastness of many varieties cannot meet the needs

Abstract

The invention discloses a composite disperse dye composition. The composite disperse dye composition comprises a component A and a component B. The component A comprises one or more compounds shown in the formula 1. In the formula 1, R1 represents H or -NHCOCH3 and R2 and R3 respectively represent C1-C4 alkyl, -CH2CH2COOCH3 or -CH2CH2OCH3. The component B comprises one or more compounds shown in the formula 2. In the formula 2, R4 and R5 respectively represent H or Cl. The composite disperse dye composition has excellent level-dyeing properties, color fastness to sunlight, color fastness to washing, color fastness to rubbing and the like, and through the use of the component B, sublimation fastness of the composite disperse dye composition is improved obviously.

Description

technical field [0001] The invention relates to a disperse dye composition, in particular to a composite disperse dye composition suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] Disperse dyes have small molecules and no water-soluble groups in their structure. They are uniformly dispersed in the dyeing solution with the help of dispersants for dyeing. It can dye polyester fiber, acetate fiber and polyester amine fiber, and become a special dye for polyester. Disperse dyes can be roughly divided into disperse orange, disperse blue, disperse yellow, and disperse red. Several different disperse dyes can be matched in a certain proportion to obtain disperse black, disperse green, disperse violet and other disperse dyes. [0003] Disperse Blue 148# is a new class of heterocyclic disperse dyes launched by BASF in Germany. Its structural formula is as follows: [0004] [0005] The dye has bright color, high strength, good fast...
