    Abstract: A work glove including a glove base material made of fiber and a foam layer composed of a thermoplastic resin or a rubber provided thereon, the foam layer having irregularities formed by heat press on the surface is provided. Heat press induces collapse and thermal fusion of foam, leaving traces of the foam on the surface of a foamed material. The foam layer produced by this technique has both film strength and abrasion resistance without deterioration in the non-slip properties usually possessed by the foam layer.
