Abstract
A pattern is placed on a porous transfer sheet by the use of sublimable dyes. Carpet face yarns are tufted into a backing material. The transfer sheet is placed adjacent the back of the carpet on the side of the carpet opposite from the carpet face yarns. Heated air causes the sublimable dye to move from the transfer sheet, through the carpet backing to the face yarns of the carpet to provide the dye pattern on the face yarns.
