摘要:
The present invention relates to absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or panty liners which have an aperture film topsheet on the surface facing the wearer in use. According to the present invention the articles are provided also with an apertured backsheet for breathability. The backsheet comprises at least one breathable layer of a resilient, three-dimensional web which consists of a liquid impervious polymeric film having apertures. These apertures form capillaries which are not perpendicular to the plane of the film but are disposed at an angle of less than 90° relative to the plane of the film.

The present invention relates to absorbent articles such as sanitary napkins and the use of breathable backsheet constructions therein to provide improved topsheet performance. In particular, the present invention relates to a moisture vapour permeable, liquid impermeable backsheet and its use for the provision of a dry wearer facing surface, preferably a topsheet of an absorbent article.

Absorbent members and methods of making the same are disclosed. In one embodiment, the absorbent member is a unitary absorbent fibrous web having a density profile through its thickness. In such an embodiment, the density profile may be relatively centered through the thickness of the web and the maximum density of the web is located between about 35% and about 65% of the distance through the thickness of the web.

An anatomically shaped disposable absorbent article having a front end portion and a rear end portion and a periphery, and comprising a liquid pervious topsheet, a multilayer backsheet joined to said topsheet and an absorbent core intermediate the backsheet and the topsheet. The anatomically shaped disposable absorbent article has lobes provided by the topsheet and the backsheet extending beyond the absorbent core and has a reduced tendency to form folds in the lobes during the use.

The present invention relates to resilient, three dimensional, perforated plastic webs which allow passage of water vapour, and preferably of 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 apertures. Theses apertures 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. The capillaries also have a length L which has a preferred value as compared to the distance that separates a capillary from adjacent ones. The present invention also relates to absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or pantiliners which have a topsheet on the surface facing the wearer in use. According to the present invention the articles are provided also with an apertured backsheet for breathability. The backsheet comprises at least one breathable layer of a resilient, three dimensional, perforated plastic web as described above.

The present invention relates to resilient, three dimensional, perforated plastic webs which allow passage of water vapour, and preferably of air, but 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 comprising apertures which form capillaries having a length which is at least twice if compared to the dimension of the respective aperture in the polymeric film surface. The present invention also relates to absorbent articles like baby diapers, adult incontinence articles and in particular to sanitary napkins or pantiliners which have a topsheet on the surface facing the wearer in use. According to the present invention the articles are provided also with an apertured backsheet, preferably for breathability. The backsheet comprises at least one layer of a resilient, three dimensional, perforated plastic web as described above.
摘要:
A breathable microporous film having improved extensibility is disclosed. The microporous breathable film is formed from a mixture of a thermoplastic polymer and particles of an inorganic filler, and is provided with breathability by stretching it in at least one direction. The microporous film is provided with a better extensibility by selecting the particle size of the inorganic filler, and the moisture content of the particles of inorganic filler and of the thermoplastic polymer when they are blended together to provide the mixture, and by controlling the Dart Resistance of the film. A composite layered breathable structure comprising the microporous film is also disclosed, and moreover a disposable absorbent article comprising a microporous breathable film which is imparted extensibility by means of mechanical straining.
