Abstract
A carpet printing method is disclosed, and an apparatus for carrying out the method. The method includes the steps of supporting a piece of fabric on a perforate belt, generating a foam adjacent to the fabric and directing the foam through the belt to treat the fabric. The apparatus includes a pan having pipes for admitting dye and air into the pan to generate a foam. A belt is disposed across the open top of the pan, the belt carrying the fabric. The air both foams the liquid and provides pressure within the pan to urge the foam through the belt and into the fabric.
Claims5
A process for treating fabric including the steps of generating a foam within an unobstructed pan having an open top, directing said foam towards said open top with the walls of said pan, placing a porous belt over the open top of said pan in sealing engagement therewith, placing said fabric on said belt, placing a porous means over said fabric for holding said fabric to assure that said fabric is against said belt, and maintaining said foam at a sufficiently high pressure that said foam passes through said porous belt and into said fabric for treatment of said fabric, and further characterized in that the step of generating a foam is carried out adjacent to said porous belt.
