Abstract
A method for producing back-foamed air-permeable textile products, whereas, instead of providing a film or the like to prevent the penetration of reaction products or foam to the visible face, the pressure created during the reaction is intentionally decreased so that none of the reaction products nor the foam created by the reaction of the reaction products is able to penetrate the textile product. With a product manufactured in this way, the climatic comfort is improved and a better acoustic effect can be achieved. The disclosure also relates to a device which is suitable for carrying out the method and to a corresponding back-foamed air-permeable textile product.
