Patent

CA 2205538

The present invention provides a garment (e.g., a surgical gown) having adhered thereto a conformable, thin polymeric barrier film (2). The barrier film provides fluid resistance to the garment while still allowing the garment to "breathe". In addition, preferred barrier films are resistant to the transmission of pathogens. The barrier film of the present invention, prior to being applied to a fabric substrate, is preferably provided as an assembly in the form of an individual sheet, a roll of material, or a pad of stacked sheets. The assembly preferably comprises a relatively thin, conformable polymeric film; a pressure sensitive adhesive (3) attached to at least a portion of one surface of said film; a means (4, 5) for protecting said adhesive prior to application of the film to a fabric substrate; and a means for handling (10) said adhesive coated film during application of said film to said fabric substrate, wherein said handling means is attached to said film more tenaciously than said protecting means is attached to the adhesive surface of said film.

La présente invention concerne un vêtement (tel qu'une blouse de chirurgien) sur lequel est appliqué un film-barrière (2) polymère, mince, apte à épouser une forme. Le film-barrière confère au vêtement une résistance aux fluides tout en le laissant toujours "respirer". De plus, les films-barrière préférés résistent à la transmission d'agents pathogènes. Le film-barrière de la présente invention, avant d'être appliqué à un substrat en tissu, se présente de préférence sous la forme d'un ensemble tel qu'une feuille individuelle, un rouleau de matériau ou une plaque de feuilles empilées. L'ensemble comprend de préférence un film polymère apte à épouser une forme, relativement mince; un adhésif (3) sensible à la pression fixé à au moins une partie d'une surface de ce film; un élément (4, 5) servant à protéger l'adhésif avant l'application du film sur un substrat en tissu; et un élément (10) servant à manipuler ce film revêtu de l'adhésif lors de son application sur un substrat en tissu, cet élément de manipulation étant fixé au film plus solidement que ne l'est l'élément de protection à la surface adhésive du film.
