| Abstract: |
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.

What is claimed is:
1. A process for the continuous production of laminated elastic fabrics having good permeability to air and/or water vapour, which process comprises coating a first web of fabric in the tensionless state with a foamed aqueous preparation which contains
- (a1) a self-crosslinking acrylate-based copolymer,
- (a2) a self-crosslinking vinyl-acrylate copolymer or
- (a3) a self-crosslinking olefin-vinyl copolymer,
- (b) optionally a curable, crosslinking, polyfunctional aminoplast precondensate or aminoplast former,
- (c) a surface-active foaming agent,
- (d) a stabiliser,
- (e) optionally a wetting agent,
- (f) optionally a thickener, and
- (g) an amine or alkanolamine containing 1 to 4 carbon atoms or ammonia,
bonding a second web of fabric, optionally under low tension, to the coated side of the first web, then drying and optionally pressing both webs together and finally subjecting them to a thermosetting treatment.
