Abstract

The invention discloses a triazine structure contained monoazo compound and a preparation method and usage thereof. The triazine structure contained monoazo compound is shown as the following formula (1), wherein each perssad is defined in the instruction. Extremely dark dyeing can be obtained when the triazine structure contained dye is used for terylene, terylene superfine fiber, combination fabrics of the terylene superfine fiber and spandex, and the triazine structure contained dye is excellent in each fastness.

Description

A technical field [0001] The invention relates to an azo compound containing a triazine structure, a preparation method and an application thereof, and belongs to the technical field of chemical material preparation. Two background technology [0002] For a long time, the coupling components used as dyes often contain acetanilide groups, such as blue 291:1, purple 93. However, they have poor washing fastness and are difficult to dye deep, especially in the case of polyester and spandex blends, it is even more difficult to dye deep, and the washing fastness is even worse. Therefore, there is a need for an economical new dye with good depth and high wash fastness. Three invention content [0003] The object of the present invention is to provide a monoazo compound containing a triazine structure, which has excellent deep color dyeing performance, light fastness, sublimation fastness and washing fastness, a preparation method and its application. [0004] The technical solu...
