摘要： A latex dipped article, particularly a fabric supported glove which is flexible and fatigue resistant, comprising a fabric liner, with a shape of a hand. The fabric liner is coated with a foam polymeric latex material which is then treated with an aqueous silicone or non-silicon based surface active agent to facilitate the formation of percolative surface structure through bursting of bubbles in the foam layer and stripped off the excess polymeric material. Then the stripped material is removed gently by exposing to a flowing fluid which further enhances the texture of the percolative coating that results an excellent grip in dry, wet and oil environments.

摘要： A multi-layered multifunctional polymeric latex article is provided. A first polymeric latex layer, having nitrile butadiene, is resistant to chemical permeation whilst the second polymeric latex layer disposed on the first layer, being a composite layer of polychloroprene and Nano clay, is resistant to chemical degradation. The third layer disposed on the second layer is a polychloroprene layer having a unique micro-roughened surface texture pattern, providing an improved grip and friction in both wet and dry conditions. The second and third layers are disposed during the wet gelled stages of the first and second layers respectively. The gelled third layer is dipped in a solvent mixture whereby a chemical reaction causes the gelled surface of the third layer to texturize by swelling and fixing, creating a continuous and discontinuous wavy micro-roughened surface which is then cured causing formation of ionic crosslinks in the third polymeric layer.
