The present invention provides a sanitary napkin that is thin (less than 5 mm in thickness), highly absorbent and has a lateral flexibility allowing for controlled deformation when in use, namely the assumption of a 'W' pattern. This controlled deformation provides a good comfort potential and simultaneously reduces the likelihood of bunching due to compression forces exerted laterally against the napkin by the thighs of the wearer. In a specific example, the sanitary napkin is characterized by a pair of preferential bending zones extending along the longitudinal axis of the sanitary napkin and by a pair of longitudinal adhesive zones on the liquid-impervious barrier layer of the sanitary napkin, that register with the preferential bending zones. The longitudinal adhesive zones fasten the sanitary napkin to the undergarment at the areas at which the sanitary napkin is intended to fold when subjected to lateral compression. This feature allows the napkin to fold and adopt a desired three-dimensional deformation profile in a predictable manner when laterally compressed.

Thin sanitary napkin allowing for controlled deformation when in use

The invention provides a sanitary absorbent article, such as a feminine protection device, having a fibrous, liquid permeable body-facing cover layer, and an absorbent system, which exhibits particular rewet characteristics when subjected to mechanical stress. The sanitary absorbent article has a thickness of less than or equal to 5 mm, a capacity of at least 18 grams, a rewet potential of less than or equal to 0.8 grams, and a flexural resistance of less than 700 g.

Sanitary napkin with improved liquid retention capability

A sanitary absorbent napkin has a laminate structure coprising a first liquid-permeable sheet of material, a second liquid-permeable sheet of material disposed adjacent the first sheet, and an absorbent member for absorbing liquid and disposed adjacent to the second sheet. The second sheet is arranged to receive the liquid deposited on the first sheet and to transfer liquid to the absorbent member. The napkin has a thickness of less than or equal to about 5 mm, when dry, and a penetration time of less than 15 seconds.

Sanitary absorbent napkin

The present sanitary napkin is thin (less than 4 mm in thickness), highly absorbent and has a flexural resistance which provides controlled deformation when in use, namely the assumption of a &ldquo;W&rdquo; pattern (good for absorption performance) or a &ldquo;M&rdquo; pattern (which enhances comfort). This controlled deformation provides a good comfort potential and simultaneously reduces the likelihood of bunching due to compression forces exerted laterally against the napkin by the thighs of the wearer. The sanitary napkin is characterized by a flexural resistance of not less than about 400 g. The sanitary napkin has a cover layer, a barrier layer and an absorbent system having at least one preferential bending zone which allows the napkin to adopt a certain three-dimensional deformation profile in response to lateral compression.

Disposable absorbent pad

Disposable absorbent product

A highly absorbent and flexible calendered and perf-embossed cellulosic pulp fluff sheet for use in disposable absorbent products such as sanitary napkins, wound dressings, bandages, incontinence pads, disposable diapers and the like. The invention also extends to a method for manufacturing the highly absorbent and flexible pulp fluff sheet and its method of use in disposable absorbent products.
