摘要

For the production of multilayer textile materials, a structure comprising a film-forming laminating adhesive and textile webs, in particular nonwovens, is proposed. This laminating adhesive enables the lamination of the textile web, is permeable to water vapour and impermeable to water, and, after radiation-curing and moisture-curing, forms the supporting material of the textile material. This laminating adhesive is prepared from mixtures of polyesters and polyethers or from polyether-esters by reaction of all the hydroxyl groups thereof with diisocyanates and reaction of some of the free NCO groups with hydroxyalkyl acrylates, followed by radiation-curing. The textile materials are produced by applying the laminating adhesive to a release layer, laminating with a first textile web, removing the release layer, and radiation-curing, thermally activing and laminating the material with the second textile web on the other side.
