    摘要： A method for the production of a breathable multilayer synthetic leather with a backing layer of a textile sheet, at least one intermediate layer applied to the backing layer and based on an at least to some extent open-cell whipped polyurethane foam and, applied full-surface to the at least one intermediate layer, an outer layer based on a polyurethane. In a first step, the outer layer is applied to a peelable underlay and is hardened, and then at least one intermediate layer is applied to the outer layer, and then the backing layer is laid onto the at least one intermediate layer and the underlay is released from the outer layer, where, to form the outer layer, an aqueous aliphatic polyurethane dispersion in liquid form is applied to the underlay, and immediately after application of the polyurethane dispersion the water content of the same is evaporated by introducing heat within a time sufficiently short to bring about filming-free drying of the polyurethane dispersion on the underlay, forming the outer layer with micropores. A corresponding breathable multilayer synthetic leather is also provided.

    摘要： 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.
