Abstract
Disclosed herein is a method for dyeing and removing colored impurities, which includes providing a polyester fabric and an adsorption material, spraying a coloring material onto a surface of the polyester fabric to form a colored layer, subjecting the polyester fabric thus dyed to a heating treatment for the colored layer to adhere to the surface of the polyester fabric, attaching or applying the adsorption material onto the colored layer and subsequently heating and/or applying a pressure to the adsorption material so that the adsorption material is coated on the colored layer to adsorb colored impurities therefrom, and removing the adsorption material.
Claims4
A method for dyeing and removing colored impurities, comprising:
- a) providing a polyester fabric and an adsorption material that is non-viscous and ductile at room temperature;
- b) spraying a coloring material onto a surface of the polyester fabric to form a colored layer on the surface of the polyester fabric, so as to dye the polyester fabric;
- c) subjecting the polyester fabric thus dyed to a heating treatment, so that the colored layer adheres to the surface of the polyester fabric, the colored layer containing colored impurities;
- d) attaching the adsorption material onto the colored layer, followed by heating and applying a pressure to the adsorption material, so that the adsorption material is softened and coated on the colored layer, and the colored impurities in the colored layer are adsorbed by the adsorption material;
- and
- e) removing the adsorption material.
