摘要： A breathable disposable absorbent articles of layered construction, each layer having a garment facing surface, and a wearer facing surface. The breathable disposable absorbent article comprises at least a first backsheet layer and a second backsheet layer. At least one of the breathable layers of the backsheet comprises a resilient, three-dimensional web, which consists of a liquid impervious polymeric film having apertures. The apertures form capillaries, which are not perpendicular to the plane of the film but are disposed at an angle of less than 90° measured from the plane of the film.

摘要： A resilient, three dimensional, perforated plastic webs which allow passage of water vapor and preferably air, and are resistant to the transmission of aqueous fluids at least in one direction. According to the present invention the perforated plastic webs consist of a liquid impervious polymeric film having open and closed capillaries. More than half of the capillaries are closed and preferably shorter than the capillaries with aperatures, and provide the resilient three dimensional web with an increased resistance crush and to collapse the capillaries under compression. The resilient, three dimensional, perforated plastic webs can be used as one of the layers of a backsheet in an absorbent articles, such as, sanitary napkins, pantiliners. baby diapers, adult incontinence, and the like.

摘要： The present invention relates to breathable absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or pantiliners. According to the present invention the articles are provided with an apertured backsheet for breathability. At least one of the breathable layers of the backsheet comprises a resilient, three dimensional web which consists of a liquid impervious polymeric film having apertures. The apertures form capillaries which are designed such that the backsheet provides an increased barrier to liquid passage out of the article and maintains water vapor permeability when the web is exposed to compressive pressure.
