摘要
A process for the continuous production of laminated elastic fabrics having good permeability to air and/or water vapor, which comprises coating a first web of fabric in the tensionless state with a foamed aqueous preparation which contains a self-crosslinking copolymer, e.g. based on acrylate, optionally a curable, crosslinking polyfunctional aminoplast precondensate or aminoplast former, a surface-active foaming agent and a stabilizer as well as, optionally, further assistants, wet bonding a second web of fabric, optionally under low tension, to the coated side of the first web, then drying both webs and pressing them together and finally subjecting them to a thermosetting treatment.
