Method and device for the production of back-foamed air-permeable textile products

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.

1 .- 5 . (canceled) 
     
     
         6 . An article comprising:
 a back-foamed air-permeable textile product in which the foam is molded and adhered to a back side of the textile product without the interposition of a film and without the foam penetrating the textile product to a visible face of the textile product;   wherein the foam is a polyurethane foam formed from liquid reaction products molded directly to the back side of the textile product; and   wherein the back-foamed air-permeable textile product is permeable to transportation of atmospheric moisture and a circulation of air.   
     
     
         7 . The article of  claim 6  wherein:
 foam cells molded directly adjacent to the back side of the textile product are opened to a greater extent than foam cells adjacent thereto.
