摘要:
A method of forming a substantially air-impermeable composite material includes introducing a sheet-form film and a loop material into a nip formed between a first roll and a second roll, introducing molten resin into the nip between the film and the loop material, and allowing the molten resin to cool so that the film becomes attached to the loop material by the cooled resin.

A process for making an embossed web includes providing a precursor web a first forming structure having a plurality of discrete first forming elements and a first pressure source and applying pressure between the first pressure source and the first forming structure to force the precursor web to conform to the first forming elements of to form a first embossed web having a plurality of first discrete extended elements. The first embossed web is then provided between a second forming structure having a plurality of discrete second forming elements and a second pressure source and pressure is applied between the second pressure source and the second forming structure to force the first embossed web to conform to the second forming elements to form a second embossed web having a plurality of second discrete extended elements. The resulting embossed web has a plurality of first and second discrete extended elements.

The present invention provides a roller nanoimprint apparatus capable of preventing a workpiece film with nanostructures having been transferred from the mold roller from being uneven in thickness and allowing easy replacement of the mold roller. The present invention is a roller nanoimprint apparatus including a mold roller and continuously transferring nanosizedprotrusions to a surface of a workpiece film by rotating the mold roller, wherein the mold roller is a cylindrical body having an outer circumference surface with nanosized recesses formed thereon, the roller nanoimprint apparatus further includes a fluid container having an elastic film inflatable by injecting fluid into the container, the fluid container being arranged in a region defined by an inner circumference surface of the mold roller, the mold roller is mounted or demounted when the elastic film is shrunken, and the mold roller is supported from the inside when the elastic film is inflated.
