Process for the production of coated textiles
A process for the production of coated textiles comprises the steps of: providing a textile substrate having a first side and a second side opposing the first side; contacting at least a part of the first side of the textile substrate with a spreadable polyurethane mechanical foam; applying a reduced pressure to at least a part of the second side of the textile substrate opposing the first side which has been contacted with the polyurethane mechanical foam; and solidifying the polyurethane mechanical foam with which the textile substrate has been contacted. The invention further relates to a coated textile obtainable by such a process, in particular a synthetic leather.
