Abstract
A pattern is printed with adhesive as a design on certain selected areas of a shrinkable substrate and the adhesive is dried. Flock is preferably applied to the selected design prior to drying. Supplemental adhesive is then applied to other areas ("background" areas) of the substrate, and is dried. Preferably such supplemental adhesive is applied over the surface of the entire substrate and over the adhering flock that has already been applied, and the entire substrate plus existing flock is covered with additional flock, followed by drying of the adhesive. The entire substrate thus prepared is then subjected to shrinkage, causing differential shrinkage of the design areas and the background areas, and producing a fabric having a novel three-dimensional pattern or design. The fabric product preferably has a plurality of upstanding flock fibres and the substrate is shrunken more tightly in some areas than in others.
