A method of carpet treating and apparatus for the dyeing of intricate patterns is provided wherein a plurality of spray nozzles are disposed in a spray line transverse to the direction of movement of a carpet. Each spray nozzle is connected to a mixing chamber where air and treating liquid preferably dye, are applied at selected pressures between 0 and 60 p.s.i. Depending on the relative pressure of the air and liquid dye, the mixture is caused to be either atomized or foamed through the spray nozzles onto the face of a moving carpet web. Each nozzle is connected to its own separate mixing chamber the input of which are controlled through a corresponding control valve which turns on and off the spray nozzle by opening and closing a corresponding gas valve and corresponding dye valve.
