Abstract

The invention discloses a red dye composition. The red dye composition comprises dyes shown in the general formulas (I) and (II) and assistants. The invention also discloses a preparation method of the red dye composition and a dyeing method adopting the red dye composition. The red dye composition has the advantages of good oxidation resistance and short dyeing process.

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, ...
