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.

Provided is a porous layer structure including a base material (A) and a urethane foam layer provided on the base material (A), wherein the urethane foam layer is a foam layer formed by foaming a urethane prepolymer having an isocyanate group, the urethane foam layer has a density of 0.10 to 0.60 g/cm.sup.3, and the urethane prepolymer substantially contains no volatile component and satisfies a predetermined composition.

The present invention relates to a coated fabric for an air bag obtained by applying an elastomer resin onto at least one side of a woven fabric made from synthetic fiber. The applied amount of the elastomer resin is 25 to 60 g/m.sup.2. The average resin thickness on warp and weft at head top of the woven fabric surface is 8 μm to 45 μm. The number of foams having diameter of 30 μm or larger is 100 or more/cm.sup.2 on the surface of a resin layer.

A method for producing a breathable film based on polyvinyl chloride (PVC), including the following steps. Preparing a paste-like compound including a first fraction composed of PVC, a second fraction composed of a foreign material, and a third fraction composed of adjuvants and/or additives that that are mixed together to form the paste-like compound, applying the paste-like compound to a base, and drying and gelling the paste-like compound, which has been applied to the base, through the addition of heat, thus forming the film in which pores extending from the one surface of the film to the other are formed, which give the film breathability.

A composite material formed by combining a polyurethane material with an unclickable foam layer and a scrim layer through roll and flat form technology. The composite material is embossed to form pillowlike chambers or cells delineated by a network of emboss pattern lines formed by the bonding between these layers.

A composite scaffold having a highly porous interior with increased surface area and void volume is surrounded by a flexible support structure that substantially maintains its three-dimensional shape under tension and provides mechanical reinforcement during repair or reconstruction of soft tissue while simultaneously facilitating regeneration of functional tissue.

Textiles backed with a polyurethane cushion are produced by applying a layer of frothed polyurethane-forming mixture to a surface of the textile. The mixture contains both water and a physical blowing agent. The layer expands due to the action of the water and the physical blowing agent and cures to form an attached cushion having a density of 176 g/L or less.

A composite scaffold having a highly porous interior with increased surface area and void volume is surrounded by a flexible support structure that substantially maintains its three-dimensional shape under tension and provides mechanical reinforcement during repair or reconstruction of soft tissue while simultaneously facilitating regeneration of functional tissue.

The present invention relates to a man-made leather having excellent air permeability and manufacturing method thereof, and more particularly, to a man-made leather having excellent air permeability capable of maintaining a permeability by urethane-coating only on a cotton portion of base fabric (20) formed with holes and capable of pattern transfer on release paper, and manufacturing method thereof.

According to the man-made leather having excellent air permeability and manufacturing method thereof, the air permeability can be maintained on the man-made leather by urethane-coating only on a cotton portion of base fabric (20) formed with holes while maintaining the luxury of fabric texture per se and toughness.

The use of long-chain citric acid esters as additives in aqueous polymer dispersions for production of porous polymer coatings, preferably for production of porous polyurethane coatings, is described.
