US Patent 3,766,872, granted October 23, 1973, describes a textured embroidered fabric and the process for making it. A first face yarn is stitched with a soluble bobbin yarn (polyvinyl alcohol) and overlaid by a second face yarn secured with an insoluble bobbin yarn. Boiling dissolves the soluble yarn, freeing the first stitches to form a textured, raised mass that is then finished and brushed. The patent covers preferred materials (low-twist, heat-shrinkable polyester; polyester-cotton ground), Schiffli machine embroidery, a worked example, and five claims, with drawings of the fabric at successive stages.
