Abstract

The invention discloses a dye composition. The dye composition is composed of dyes having structures represented by general formula (I), general formula (I), general formula (II), general formula (III) and general formula (IV) respectively, and assistants. The invention also discloses a preparation method of the dye composition, and a dyeing method of the dye composition. The dye composition obtained in the invention has a good oxidation resistance, and the dyeing method using the dye composition has a short flow.

Description

technical field [0001] The invention belongs to the field of chemical industry, and more specifically relates to a dye composition and a preparation method thereof. Background technique [0002] When the polyester fabric contains PVA pulp, because the macromolecular PVA is extremely difficult to remove, at present, strong alkali / surfactant, strong alkali / oxidant (such as hydrogen peroxide, etc.) are used for desizing, and the desizing agent containing oxidant can Oxidation degrades macromolecular PVA into small molecules, and the resorption / adhesion ability of degraded PVA to dyes and fibers is weakened, which is conducive to the improvement of dyeing uniformity and color fastness (such as washing fastness and rubbing fastness). However, only using strong alkali / surfactant has the disadvantage of desizing and uncleanness. Because of the strong binding force between macromolecular PVA and fiber, the PVA remaining on the fiber cannot be effectively removed during acid dyeing, ...
