Problems solved by technology

[0005] The disadvantage of this color masterbatch is that only bisphenol A type liquid epoxy resin and other auxiliary agents are used to load dyes, and it is still necessary to make a dye solution when used. This traditional dyeing process makes the dye-loaded resin and auxiliary agents It is still only attached to the surface of the polyester fiber, and there is inevitably a limitation of the level dyeing caused by the traditional dyeing process; and the fuel only attached to the surface of the fiber also has the problem of poor color fastness, and the dye molecules that have been adsorbed on the fabric are still dyed. Migration is easy to occur, which also poses a great challenge to whether the level dyeing of the fabric can be maintained

Abstract

The invention discloses color master batch capable of improving the level dyeing property and a preparation method of the color master batch. Raw materials of the color master batch comprise carrier resin and super absorbent resin, wherein the super absorbent resin is a grafted copolymer formed by grafting starch or cellulose with at least two hydrophilic monomers, and a disperse dye is adsorbed in the super absorbent resin. The super absorbent resin is added to the color master batch and used for loading the disperse dye, countless 3D space network structures are distributed in the super absorbent resin formed by graft polymerization of the starch and at least two hydrophilic monomers, when the super absorbent resin is soaked in a suspension of the disperse dye, the disperse dye can enterthe 3D space network structures with water, and when the super absorbent resin is dried, water molecules are evaporated and the disperse dye is firmly locked in the super absorbent resin. When the color master batch is utilized for preparing polyester fibers, the disperse dye can be uniformly dispersed into the polyester fibers without migration, and therefore, the level dyeing property of the disperse dye is guaranteed to the greatest degree.

Description

technical field [0001] The invention belongs to the technical field of color masterbatches, and in particular relates to a color masterbatch for improving level dyeing property and a preparation method thereof. Background technique [0002] Levelness refers to the ability of a dye to level itself on a fabric during the dyeing process. In addition to being affected by the physical properties of dye molecules and fiber substrates, it is also restricted by various factors such as temperature, dyeing rate, and dyeing auxiliaries used. Therefore, it is often difficult to obtain a fabric with better level dyeing property by directly dipping the fabric into the dyestuff for dyeing. [0003] In order to improve the level dyeing of fabrics, the Chinese invention patent application with application number CN 201710599876.6 discloses a color masterbatch for improving the level dyeing of polyester webbing. The color masterbatch is made of the following raw materials in parts by weight:...
