A method of treating carpet and apparatus for dyeing of carpet 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. A method and apparatus for solid color dyeing uses a number of reciprocating spray nozzles, each spray nozzle receiving mixed dye and air from a corresponding mixing chamber and spraying the dye, which is foamed or atomized by the air, directly onto a carpet. Separate valves control the dye going into each mixing chamber and are mounted on a fluid control chamber. The field of spray width is adjustable such that different width carpets may be dyed.
