ABSORBENT STRUCTURE COMPRISING CO-FORMED LAYER

An absorbent structure is disclosed, which may be or form part of an absorbent core of an absorbent article. The structure has a caliper, a fluid-receiving side and a non-receiving side. The non-receiving side occupies a first x-y plane; the receiving side occupies a second x-y plane. The structure has a first zone constituting a first portion of the caliper proximate the non-receiving side, and a second zone constituting a second portion of the caliper proximate the receiving side. Each of the zones includes a co-formed blend of constituents. The blend may include AGM particles, spun filaments and/or cellulose fibers. In examples including AGM particles, particles in the first zone may have an average particle size smaller than that of particles in the second zone. In examples including filaments, filaments in the first zone may have an average filament size smaller than that of the filaments in the second zone.

Unitary absorbent structures comprising an absorbent core and/or an acquisition and dispersion layer for absorbent articles
10905604 · 2021-02-02 · ·

The present invention relates to a unitary absorbent structure and method thereof wherein said unitary absorbent structure comprises an absorbent core (5) and/or an acquisition and dispersion layers (2) (3) and comprising at least one non-woven fibrous substrate layer (23) having a void volume suitable to be penetrated by super absorbent particles. The super absorbent particles are dispersed in the substrate layer (23) according to a size distribution gradient by vacuum (8) and vibration along the depth direction or z-direction of said absorbent core (5) and/or acquisition (2) and dispersion (3) layers, the smaller particles are placed on the bodyside of the absorbent articles and the larger particles are located on the opposite side of the absorbent articles.

LINE-UP OF ABSORBENT ARTICLES HAVING MATCHING WAIST CIRCUMFERENCES
20180228664 · 2018-08-16 ·

A line-up of at least three hygiene absorbent articles of different sizes, each article comprising a pair of fasteners separated by a wingspan (W) that can be fastened to a fastening area (44) on the front region of the article so that the front region and the waist region form a waist opening. The fastening area in the front region comprises an innermost pair of fastening indicia (A-A), an outermost pair of fastening indicia (C-C) and preferably at least one intermediate pair of fastening indicia (B-B). The outer waist circumference of the article of a given size matches within 30 mm the inner waist circumference of the article of the next upper size in the line-up, the circumferences being calculated by adding the wingspan and the spacing between the innermost pair or outermost pair of indicia respectively.
