    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.

    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 sanitary napkin comprising a fluid permeable topsheet, a fluid permeable backsheet, and an absorbent core disposed therebetween is disclosed. The sanitary napkin can be a pantiliner. The absorbent core comprises relatively hydrophilic material defining a core outer periphery. The topsheet and the backsheet comprise relatively hydrophobic nonwoven material, at least one of the topsheet and the backsheet defining a sanitary napkin outer periphery that is substantially larger than the core outer periphery. The area between the core outer periphery and the sanitary napkin outer periphery is a breathable zone. The sanitary napkin further comprises a fluid impermeable barrier between the backsheet and the absorbent core, the fluid impermeable barrier being disposed within the core outer periphery.
