Abstract

See full text

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.
