Abstract
A spray dyeing method includes continuously moving a substrate in a direction; spraying an organic pigment onto the substrate using a spraying system while moving the substrate forward through a dyeing station; and allowing the substrate coated with the organic pigment to pass through a drying station including an infrared irradiation unit to cure the organic pigment. Using the spray dyeing method, in fiber or fabric dyeing, it is possible to dye using a much smaller amount of water by opening a molecular structure of a polymer that makes up the substrate through infrared irradiation after dyeing by pigment spraying to cure the pigment.
Claims4
A spray dyeing method, comprising:
- continuously moving a substrate in a direction;
- spraying an organic pigment onto the substrate using a spraying system while moving the substrate forward through a dyeing station;
- and
- allowing the substrate coated with the organic pigment to pass through a drying station including an infrared irradiation unit to cure the organic pigment,
- wherein curing the organic pigment comprises:
- irradiating infrared light in a first wavelength band onto the substrate coated with the organic pigment;
- and
- after irradiating the infrared light in the first wavelength band, irradiating infrared light in a second wavelength band onto the substrate, wherein the second wavelength band is different from the first wavelength band.
