High-fastness black and blue disperse dye composite

Abstract

The invention discloses a high-fastness black and blue disperse dye composite, which comprises the following components in percentage by weight: 7 to 42 percent of component A, 45 to 90 percent of component B and 3 to 13 percent of aids, wherein the component A is a compound shown by a formula (I), and the component B is one or more of compounds shown by a formula (II). The high-fastness black and blue disperse dye composite provided by the invention has excellent levelling property, beautiful and bright color light, strong deep dyeing property, high color yield and excellent fastness such as sublimation resistance fastness, washing resistance fastness, friction resistance fastness and the like, and particularly by the addition of the component A, the sublimation fastness of the black and blue disperse dye composite is improved obviously.

Description

technical field [0001] The invention relates to the field of preparation of disperse dyes, in particular to a high fastness black and blue disperse dye composition. Background technique [0002] In recent years, disperse dyes have developed very rapidly in my country, and the varieties of disperse dyes have also increased year by year. However, the overall quality of disperse dyes is still in an unstable state. From the results of national supervision and spot checks over the years, it can be seen that the quality pass rate is still fluctuating, sometimes even very big. [0003] At present, the disperse dyes exported by my country are of good quality whether they are filter cakes or finished products, but the disperse dyes that exist in the domestic market contain relatively high content of secondary dyes, impurities, salt and heavy metals, etc., and the composition is complex and the melting point is relatively high. Low, under the same conditions, it will inevitably affect ...

Problems solved by technology

[0002] In recent years, disperse dyes have developed very rapidly in my country, and the varieties of disperse dyes have also increased year by year. However, the overall quality of disperse dyes is still in an unstable state. From the results of national supervision and spot checks over the years, it can be seen that the quality pass rate is still fluctuating, sometimes even very big

[0003] At present, the disperse dyes exported by my country are of good quality whether they are filter cakes or finished products, but the disperse dyes that exist in the domestic market contain relatively high content of secondary dyes, impurities, salt and heavy metals, etc., and the composition is complex and the melting point is relatively high. Low, it will inevitably affect the dye uptake, shade and color fastness of the dye under the same conditions

At present, the problem reflected in the market is that most disperse dyes contaminate other fibers seriously, and the sublimation fastness, thermal migration fastness and wet rubbing fastness of many varieties cannot meet the needs.
