Embodiment Construction

[0023] The present disclosure relates to a hygienic absorbent product, such as a sanitary napkin, panty liner, incontinence guard or diaper. Absorbent products comprise an absorbent core disposed between a liquid-permeable topsheet and a liquid-impermeable backsheet. The absorbent product has a transverse rear end edge intended to be oriented rearwardly during use of the absorbent article and a front end edge intended to face forward towards the belly of the wearer. The absorbent core comprises an absorbent fibrous layer disposed on the side of the absorbent core closest to the liquid impermeable backsheet, and a liquid inlet foam layer disposed on the side of the absorbent core closest to the liquid permeable topsheet, and A carrier layer disposed between the liquid inlet foam layer and the absorbent fibrous layer. Absorbent products comprising foam materials are experienced as soft and are also aesthetically pleasing to many users. The continuous structure of many foam mat...

Abstract

An absorbent product includes a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core enclosed between the topsheet and the backsheet. The absorbent core includes an absorbent fibrous layer, a liquid inlet foam layer, and a carrier layer, in which a transversally central region is arranged in the liquid inlet foam layer. The transversally central region extends along the entire longitudinal length of the absorbent core and includes a plurality of slits arranged in a pattern, wherein the slits are dilated slit openings in a part of the central region within an intermediate portion of the absorbent core, and the slits are non-dilated slits in parts of said central region within one or both of front and rear portions of the absorbent core.

Description

technical field [0001] The present invention relates to an absorbent product, such as a sanitary napkin, comprising a liquid-permeable topsheet, a liquid-impermeable backsheet and an absorbent core enclosed therebetween, and to a method of making such an absorbent product . Background technique [0002] For absorbent products such as sanitary napkins, it is required that they be unobtrusive, soft and comfortable to wear and at the same time have reliable safety against leaks. [0003] For sanitary napkins designed to absorb menstrual fluids that are more viscous than urine, it is generally more difficult for body fluids to reach the absorbent core beneath the topsheet. Under the influence of the user's gravity, motion and pressure, menstrual fluid may readily migrate on the user-facing side of the topsheet. Migration of menstrual fluid to the edges of the product increases the likelihood of leaks and further smears menstrual fluid to the user's skin making cleanup more dif...
