Abstract
Processes for dyeing fabric are provided. The process can include continuously moving the fabric in a machine direction; removing folds or creases from the fabric; spraying a first surface of the fabric with a dye; and exposing the fabric to atmospheric steam after spraying the dye on the first surface but prior to the dye drying on the first surface so that the dye migrates from the first surface to a second surface of the fabric and reacts with and affixes to a component of the fabric.
