  • Patent number: 5156891
    Abstract: Resin-coated bottoms of pockets to provide extended life for the porous material. Coating one side of the pocket bottoms provides enhanced abrasion resistance and reduces seam slippage along the stitching on the pocket's bottom. The resin may include a polyurethane or a polyacrylate, with a polyester polyurethane combination finding particular utility. The resin fills many of the pores of material, but leaves others open. The open pores avoids perspiration and other moisture from adhering to the wearer's skin. Coloring the resin helps identify the resin's presence as well as providing an indication of origin for the garment or pocket itself. Typically, the only manufacturing of the pocket includes coating one side of the pocketing material with the uncured resin. The compound embedded on one side of the material then undergoes curing, generally through the application of heat, to form a coherent substance and open the pores.
