Absorbent product comprising colored areas

Abstract

An absorbent product comprising a liquid permeable topsheet (7), a liquid impermeable backsheet(8), and an absorbent core (11) enclosed between the topsheet (7) and the backsheet (8), said absorbent core (11) comprising an absorbent fibrous layer (9), a liquid inlet layer (1), and a carrier layer (10), in which a transversally central region (4) isarranged in the liquid inlet layer (1), said region (4) extending along the entire longitudinal length (L1) of the absorbent core (11), and comprising a plurality of slits (2) arranged in a pattern, wherein the slits (2) are in the form of dilated slit openings (3a) in a part of said central region (4), which is comprised in an intermediate portion (16) of the absorbent core, and the slits (2) are in the form of non-dilated slits (3b) in parts ofsaid central region (4), which are comprised in one or both of front and rear portions (15, 17)of the absorbent core; and a method of manufacturing an absorbent product (100), comprising the steps of: cutting (130) slits (2) in a central region (4) of a continuous web of liquid inlet material (101) and extending (131) the web transversally in the cross machine direction, whereby the slits (2) aredilated into openings (3a);applying adhesive (132) to a continuous web of carrier material (110);combining (133) the continuous web of liquid inlet layermaterial (101) and cutting (134) inlet layer components (126) from the combined web (125);providing (135) absorbent components (122); enclosing (136) the inlet layer component (126) and absorbent component (122) between continuous websof topsheetmaterial (107) and backsheet material (108); joining (137) at least the topsheet material (107) and the backsheet material (108) along the outer edges of the absorbent product;cutting (138) the combined material into a desired shape, thus obtaining the absorbent product (100).

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...
