Problems solved by technology

[0003] At present, there are many disperse violet dye compositions mixed in the Chinese market, 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 will inevitably affect the dye uptake rate, shade and dyeing fastness
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

[0033] According to the data shown in Table 1, dye component A, component B and auxiliary agent diffusing agent NNO (sodium methylene bis-naphthalene sulfonate), dispersant MF (methylnaphthalene sulfonic acid formaldehyde condensate), diffusing agent CNF (benzyl naphthalene sulfonate formaldehyde condensate), sodium lignosulfonate (such as commercially available dispersants Reax 83A, Reax 85A), etc., after adding water and blending, grind and disperse with a sand mill, and then spray dry. The dye components and auxiliary agents therein can be prepared by methods known in the art, and commercially available products can also be used.

Abstract

The invention relates to a disperse violet complex dye composition. The disperse violet complex dye composition is composed of a component A shown in formula (1) and a component B shown in formula (2). In the formula (1), R1 is H or -NHCOCH3, R2 and R3 are respectively C1-C4 alkyl, -CH2CH2COOCH3 or -CH2CH2OCH3; in the formula (2), X3 is H, NHCOCH2CH3 or NHCOCH3, R2 is CH2CH2OCOCH3 or CH2CH2CN. The composition provided by the invention is simple in components, bright in colour, excellent in each fastness such as colour fastness to sunlight, colour fastness to washing and fastness to rubbing, particularly the sublimation fastness is significantly improved. The formula (1) is as shown in the specification.

Description

technical field [0001] The invention relates to a disperse dye composition, in particular to a disperse violet composite dye composition suitable for dyeing and printing polyester and its blended fabrics. Background technique [0002] Disperse dyes can be roughly divided into disperse orange, disperse blue, disperse yellow, disperse red, etc., and several different disperse dyes can be matched in a certain proportion to obtain disperse black, disperse green, disperse violet and other disperse dyes. [0003] At present, there are many disperse violet dye compositions mixed in the Chinese market, 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 dye uptake rate, shade and dyeing fastness of the dye. Moreover, the contamination to other fibers is serious...
