Abstract
Abstract An improved abrasion and cut resistant surface is provided for work gloves, work shoes and like wearing apparel. The surface of the invention provides a porous surface particularly useful in work environments where it is necessary for a workman to use gloves, but which gloves are breathable and have moisture absorbing properties. The surface of the invention is a foam surface laminated to a substrate. The foam, prior to lamination, may be foamed with varying amounts of air depending upon the degree of abrasion resistance required. The foaming may be by mechanical or chemical means.
