Problems solved by technology

[0002] In disperse dyes, blue-black series dyes are used in a large amount, but at present this series of dyes is difficult to have excellent dyeing performance and fastness performance at the same time, such as the dyeing color fastness of dyes in the patent CN1085924A is excellent, but the lifting power is poor; CN101768376A The dye lifting power in CN102344694A is good, but the light fastness is unsatisfactory; the dye lifting power and light fastness in CN102344694A are all very good, but the product chlorinated benzene and chlorinated toluene (Chlorinated benzenes and toluenes) content does not meet Oeko -Tex Standard 100 requirements

Abstract

The invention provides a composition of blue to black disperse dyes. The dyes mainly comprise the ingredients in parts by mass of 1-55 parts of at least one component A of which the structure is shown in the formula (I), 25-85 parts of at least one component B of which the structure is shown in the formula (II), and 5-45 parts of at least one component C of which the structure is shown in the formula (III). The composition of the disperse dyes disclosed by the invention can supply and dye in a micro-pelletized liquid state, a paste state or a powder and particle state which is dried by a spray drying process and the like, and a granular state after being commercialized. When the composition of the disperse dyes disclosed by the invention dyes the hydrophobic fiber materials, each dye performance and the color fastness are excellent and accord with the demands of Oeko-Tex Standard 100; and the blue to black fabrics can be obtained by adjusting the ratio of different components.

Description

(1) Technical field [0001] The invention relates to a blue to black disperse dye composition, in particular to a blue to black disperse dye composition suitable for printing and dyeing hydrophobic fiber materials. (2) Background technology [0002] In disperse dyes, blue-black series dyes are used in a large amount, but at present this series of dyes is difficult to have excellent dyeing performance and fastness performance at the same time, such as the dyeing color fastness of dyes in the patent CN1085924A is excellent, but the lifting power is poor; CN101768376A The dye lifting power in CN102344694A is good, but the light fastness is unsatisfactory; the dye lifting power and light fastness in CN102344694A are all very good, but the product chlorinated benzene and chlorinated toluene (Chlorinated benzenes and toluenes) content does not meet Oeko -Tex Standard 100 requirements. Chlorinated benzene and chlorinated toluene are not easy to decompose, not only have inhibitory a...
