Abstract
(EN)
A disposable absorbent hygiene product (1) is provided, comprising a main part (10) having an body facing surface intended to face the body of a user and a garment facing surface intended to face away from the body of a user, the main part comprising a liquid permeable topsheet (11) at the body facing surface, a liquid impermeable backsheet (12) at the garment facing surface, and an absorbent assembly (13) arranged between the topsheet and the backsheet; main part having a having a front end (14) and a back end (15), and defining a longitudinal direction (L) from said front end towards said back end and defining a transversal direction (T) perpendicular to the longitudinal direction, wherein the absorbent assembly (13) is divided by two, imaginary, transversally extending lines (T 1, T2) into a front region (Rf) towards said front end, having a longitudinal length of from 10 to 40% of the absorbent assembly longitudinal length; a back region (R b) towards said back end, having a longitudinal length of from 10 to 40% of the absorbent assembly longitudinal length; and a central region (R c) between said front region and said back region, wherein in the front and back regions, the absorbent assembly comprises cellulosic fibers optionally mixed with super absorbent polymers, with a super absorbent polymer concentration of from 0 to 30 weight%, based on the total weight of cellulosic fibers and super absorbent polymer, and a cellulosic fiber basis weight of from 50 to 200 g/m2; and wherein said central region provides from 70% to 100% of the total retention capacity of the absorbent assembly, wherein the liquid permeable topsheet material comprises a hydrophilically treated polypropylene spunbond nonwoven or spunbond/meltblown composite nonwoven, having a basis weight of from 8 to 20 g/m2; and wherein an acquisition layer material is provided sandwiched between said topsheet and said absorbent assembly, being an through air bonded nonwoven having a basis weight of from 40 to 60 g/m2 and a caliper of at least 0.9 mm as measured according the method NWS P 120.6, option A, at 0.5 kPa pressure.
