Problems solved by technology

[0003] For example, in the printing and dyeing of hydrophobic synthetic materials, the traditional black and blue dyes mixed with C.I. Disperse Blue 291:1, C.I. Disperse Violet 93, and C.I. It is not satisfactory when blending fibers such as / cotton, polyester / ammonia, etc., and because the compounded dyes will crack under certain conditions to produce aromatic amines that are harmful to the human body, they have been listed as banned azo dyes by the European Union

Abstract

The invention provides a composition of disperse black dyes, which mainly comprises one or a plurality of components A, the structures of which are shown as the formula (I), one or a plurality of components B, the structures of which are shown as the formula (II), one or a plurality of components C, the structures of which are shown as the formula (III) and one or a plurality of components D, the structures of which are shown as the formula (IV). The composition of the disperse black dyes of the invention, after merchandizing treatment, can be provided for dyeing at liquid state or cream state after being corpuscular or at powder state and granule state after being dried by a spray drying method. When hydrophobic fiber materials are dyed with dyestuff prepared by the composition of the disperse black dyes of the invention, black dyed fabric with excellent washing fastness and well performed sun-proofness and perspiration-proofness can be obtained by adjusting the proportion among different components. The composition of the invention is particularly applicable to the printing and dyeing of medium-high grade plus materials such as superfine denier fabric and the blend fabric of polyester / cotton and polyester / ammonia.

Description

(1) Technical field [0001] The invention relates to a disperse black dye composition, in particular to a disperse black dye composition suitable for printing and dyeing hydrophobic fiber materials. (2) Background technology [0002] With the development of ultra-fine polyester fiber and the development of polyester, spandex, cotton and other blended fabrics, ordinary disperse dyes can no longer meet their dyeing needs during printing and dyeing. Decreased fastness, stains are not easy to remove and other problems. In addition, due to the slow development of new structures of disperse dyes, it is increasingly important to commercialize existing products. Through the research on compounding synergies of disperse dyes, a new disperse dye composition is composed of specific components, so that it has excellent dyeing performance and fastness performance, and is used for printing and dyeing of hydrophobic fiber materials, especially medium and high-grade hydrophobic fiber materi...
