Abstract

The invention discloses an active deep blue dye composition and a high-solubility active deep blue dye, and a preparation method and applications of the high-solubility active deep blue dye. The high-solubility active deep blue dye comprises 10-90 parts by weight of a component A represented by a formula (I), 10-90 parts by weight of a component B represented by a formula (II) and 0-50 parts by weight of an auxiliary agent. The composition as the active deep blue dye has the following advantages of high solarization fastness, high elevating power, high color fixation rate, high solubility, good level-dyeing property and good dyeing stability.

Description

technical field [0001] The invention belongs to the technical field of dye preparation, and in particular relates to a highly soluble reactive dark blue dye and a preparation method and application thereof. Background technique [0002] With the continuous increase of fiber varieties and the continuous development of dyeing technology, the dye market has higher and higher requirements for the dyeing performance and dyeing process of reactive dyes, which poses a great challenge to the improvement of the application performance of reactive dyes. Many varieties in the dyeing industry, such as reactive blue 2G and reactive blue BF, have been difficult to meet the requirements of customers and the market. Traditional reactive dark blue dyes generally have disadvantages such as low color fixation rate, low light fastness, and low solubility. Therefore, it is of far-reaching significance to research and develop reactive dark blue dyes with high color fixation rate, high light fast...
