Title: 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 of said 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) are dilated 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 topsheet material (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).
