METHOD FOR FORMING A COMPOSITE ELASTIC MATERIAL |
摘要 |
A method for forming a composite elastic material. An elastic member having at least one elastic strand is fed onto a rotating forming structure exhibiting a multiplicity of apertures therein. The elastic member has a surface facing the forming structure and another surface facing away from the forming structure. A thermoplastic film is extruded onto the surface of the elastic member facing away from the forming structure. A pneumatic vacuum is applied to the thermoplastic film and the elastic member so that the thermoplastic film is simultaneously apertured and bonded to the elastic member thereby forming a breathable composite elastic material. |
