  • METHOD AND DYE SOLUTION FOR POLYESTER FABRIC DYEING
    Publication number: 20140090188
    Abstract: A method for dyeing polyester fabric including preparing a dye solution with dye, water, a liquid carrier and an acidic agent. The dye solution is applied to the fabric in a desired pattern. The fabric and dye solution are then dried in a drier so that they reach a temperature where the carrier to enhances the permeability of the fabric and permits the dye to penetrate the fabric. The carrier is then driven out of the fabric by the dryer and no pressure is applied to the fabric during the drying process.
    Type: Application

  • Method and dye solution for polyester fabric dyeing
    Patent number: 8512420
    Abstract: A dye solution for dyeing polyester fabric including dye, a liquid carrier, an acidic agent, and a thickening agent. The carrier is selected to enhance the permeability of the polyester fabric at a certain temperature so that the dye can penetrate within the fabric. A method of printing designs on polyester fabric including creating a dye solution with water, a dye, a carrier liquid and an acidic solution. The dye solution is applied to the fabric in a desired pattern. The fabric and dye solution are then dried in as drier so that the temperature of the carrier is raised to permit the carrier to enhance the permeability of the fabric and have the dye penetrate the fabric. The carrier is then driven out of the fabric by the dryer and no pressure is applied to the fabric during the drying process.
