Abstract
A method is disclosed for imparting a graphic design to the upper surface of a fabric suitable for use as a wall or floor covering. The graphic design is formed by an elongated pile article having a plurality of filament bundles attached to an elongated support strand. The fabric may be a tufted, woven, nonwoven, flocked fabric or a needled felt. The elongated pile article may be attached to the fabric by various methods, including ultrasonically bonding, applying an adhesive, sewing, stapling or using plastic fasteners. A transfer sheet is disclosed to aid in attaching by ultrasonically bonding, the sheet being made from a fusible material having the elongated pile article is attached thereto. The transfer sheet is positioned on the fabric, the elongated pile article is then ultrasonically bonded, melting a portion of the transfer sheet material, and the unmelted portion is then removed.
