Air permeable rain barrier comprising slanted capillary apertures

摘要

The present invention relates to rain protection and rain barrier articles like raincoats, roof liners for buildings or tents and other protection covers intended to prevent entry of rainwater. According to the present invention the articles are provided with or by at least one breathable layer of a resilient, three dimensional web (55) which consists of a liquid impervious polymeric film having apertures (53). These apertures (53) form capillaries which are not perpendicular to the plane of the film but are disposed at an angle of less than 90 DEG relative to the plane of the film and installed to retard entry of rain. <IMAGE>
