Abstract

Abstract A layer of adhesive is applied over and around the damaged portion of a fabric. When the adhesive has dried the damaged portion is removed by cutting through the fabric and layer of adhesive thereby leaving an opening which is preferably round. A piece of the same fabric somewhat larger than the opening is similarly coated with a layer of adhesive and then cut to form a patch identical in shape and size to the opening formed in the fabric. The patch is then fitted in the opening in the fabric and a piece of adhesive tape applied thereover and over adjacent portions of the fabric to temporarily hold the patch in place. An adhesive which on drying and setting forms a flexible heatresistant layer is applied over the back surface of the patch and adjacent portions of the fabric. A piece of a coarsely woven cloth is then applied over the layer of adhesive while it is still soft and pressed thereagainst so that the adhesive flows into and at least partially through the interstices of the cloth. When the adhesive has substantially completely dried the piece of adhesive tape is removed from the front surfaces of the patch and fabric. The adhesive or adhesives used in the practice of this invention preferably contain a color additive designed to impart a color to the adhesive which will match or blend with the color of the fabric being mended.
