Abstract
A method and apparatus is provided for controlling the distribution of color on a web of textile material in a textile dyeing process. The apparatus includes a color sensor for sensing a selected color characteristic of the textile web, such as, for example, the distribution of color, at a sensing location downstream of a nip device of a textile padding machine. The nip device removes excess dye liquor from the textile web to dispose the textile web at an initial moisture content as it exits the textile padding machine. The amount of the dye liquor removal through the nip operation is controlled in response to the color characteristic sensed by the color sensor so that the textile web is disposed at an initial moisture content upon exiting the textile padding machine which facilitates a desired color distribution when the textile web is subsequently dried.
