  • Patent number: 8088461
    Abstract: The present invention aims to provide anti-slip gloves which exhibit excellent anti-slipping effects under slippery conditions such as wet conditions caused by moisture, detergents or oils, provide an excellent durability in repeated use, keep down production costs, and can be used in various applications. The glove of the invention has an anti-slip layer comprising pulverized fragments of a foamed melamine resin, or a mixture of pulverized fragments of a foamed melamine resin and NBR particles contained in a resin or rubber formed on the surface thereof. The pulverized fragments of the foamed melamine resin are particulate subfragments obtained by pulverizing the foamed melamine resin. The foamed melamine resin has a three-dimensional lattice structure, and the pulverized fragments of the foamed melamine resin obtained by pulverizing the foam have cut limbs extending three dimensionally, which are obtained by cutting the lattice parts.
