Problems solved by technology

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, and it can absorb dyes, resulting in Staining defects (such as color flowers, color spots, etc.)
[0003] Existing dyeing processes usually require a separate desizing step, and the process is long

Abstract

The invention discloses a dye composition which is composed of dyes disclosed as general formulae (I), (II), (III) and (IV) and assistants. The invention also discloses a preparation method and dyeing method of the dye composition. The dye composition disclosed by the invention has the advantages of favorable oxidation resistance and short process when being used in a dyeing technique.

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, ...
