摘要： A porous sheet of material is first passed through an impregnation bath containing a polymer solution and then through a coagulation bath which produces string-forming polymers physically incorporated in the pores of the sheet. The sheet is then passed between a relatively rigid vibrating means engaging one side thereof and a resilient pressure means engaging the opposite side thereof, the resilient pressure means holding the sheet of material in contact with the vibrating means. The sheet is subsequently dried.

摘要： THIS INVENTION RELATES TO A PROCESS FOR THE PRODUCTION OF A LAMINATED SHEET MATERIAL INCLUDING A LAYER OF TEXTILE MATERIAL AND A MICROPOROUS LAYER OF HIGH-POLYMER PLASTIC MATERIAL WHEREIN THE SURFACE OF THE LAMINATE COMPRISES POLYMERIC MATERIAL HAVING A MICROPOROUS STRUCTURE PROVIDED WITH EMBOSSMENTS. IN THE PROCESS, A SOLUTION OF HIGH-POLYMER PLASTIC MATERIAL IS APPLIED TO A LIQUID-AND GAS-PERMEABLE AUXILIARY SHEET MATERIAL THE SURFACE OF WHICH HAS FINE PROJECTIONS OR DEPRESSIONS CORRESPONDING TO THE DESIRED EMBOSSMENTS, THE POLYMER IS PRECIPITATED ON THE AUXILIARY SHEET MATERIAL, A TEXTILE SHEET MATERIAL BEING APPLIED TO THE LAYER OF HIGH-POLYMER MATERIAL PRIOR TO PRECIPITATION OR SIMULTANEOUSLY THEREWITH, OR AFTERWARDS, AND THE LAMINATE OF POLYMER MICROPOROUS LAYER AND TEXTILE LAYER IS SEPARATED FROM THE AUXILIARY SHEET MATERIAL.
