A process for the production of coated textiles comprises at least the steps of a) bringing a textile substrate into contact with an aqueous dispersion A comprising at least one salt and at least one modified cellulose, b) bringing a textile substrate into contact with an aqueous dispersion B comprising at least one polymer selected from the group consisting of polyurethane, polyacrylate and polybutadiene and c) precipitation of the polyurethane in or on the textile substrate. The salt of dispersion A is an organic onium salt of one or more elements of the fifth main group of the periodic table of the elements. The invention further relates to a coated textile obtainable by a process according to the invention and to the use of organic onium salts of one or more elements of the fifth main group of the periodic table of the elements for the production of coated textiles.

PERCOLATIVE SURFACE TEXTURED POLYMERIC LATEX COATING FOR A FABRIC SUPPORTED GLOVE AND METHOD OF MAKING

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.

Process for the preparation of a non-woven microfibrous suede-like synthetic fabric

The present invention refers to a process for the preparation of a non-woven microfibrous suede-like synthetic fabric that does not require the use of organic solvents and that makes it possible to obtain a finished product offering a good hand, excellent resistance to yellowing and high durability. It comprises needle-punching a felt of sea/island fibers, (a) impregnation with hot aqueous solution of PVOH having a degree of saponification of at least 94% or (b) impregnation with hot water followed by impregnation with cold PUR, removing the sea component, impregnating with PUR, coagulating the PUR, removing the PVOH, grinding the surface, dyeing and splitting in two sheets.

COAGULATION MANUFACTURING METHOD

A method for producing a coagulated article includes coagulating an aqueous urethane resin composition with an alcohol solvent having 2 to 6 carbon atoms. A coagulated article having excellent texture and having excellent texture can be obtained. Further, an alcohol solvent with the number of carbon atoms being small is used for a coagulating bath, which means that the burden on the environment is small. Therefore, a coagulated article obtained by the method can be advantageously used in producing gloves, a coating material, a simulated leather sheet, and the like. With respect to the alcohol solvent, from the viewpoint of achieving a further improvement in the texture of the coagulated article due to having high penetrating property into a resin-blended liquid and an isopropyl group having appropriate hydrophobicity, 2-propanol is preferably used.

Polishing pad

A polishing pad is provided with a compression elastic modulus of 0.17 MPa or more and 0.32 MPa or less produced by preparing a nonwoven fabric formed of bundles of ultrafine fibers with an average monofilament diameter of 3.0 m or more and 8.0 m or less, preparing a polishing pad base by impregnating the nonwoven fabric with a polyurethane based elastomer in an amount of 20 mass % or more and 50 mass % or less relative to the mass of the polishing pad base, and laminating the polishing pad base with a porous polyurethane layer containing wet-solidified polyurethane as primary component which has openings with an average opening diameter of 10 m or more and 90 m or less in its surface to serve as polishing surface layer.
