Abstract
A pattern is placed on one surface of a carpet backing by the use of sublimable dyes. A carpet facing is tufted into the backing with the face yarns on the side of the backing opposite from the side of the backing containing the pattern of dyes. Subsequent heating causes the sublimable dyes to move from the carpet backing surface through the carpet backing and then through the face yarn to provide a dyed patterned face yarn. A latex coating is provided to the carpet backing to lock the tufted carpet face yarns to the carpet backing and to lock residual dye to the surface of the carpet backing.
