A top sheet for an absorbent personal care product is a water-permeable composite web produced by hydro-entangling a web of chemical free natural and/or cellulosic staple fibers and/or blend of natural and cellulosic staple fibers and a web of man-made continuous filament yards such that a first side of the composite web exposes the chemical free natural and/or cellulosic staple fibers and/or blend of natural and cellulosic staple fibers and an opposite second side of the composite web has the man-made continuous filament yarns. The web of chemical free natural and/or cellulosic staple fibers and/or blend of natural and cellulosic staple fibers is hydrophilic and the web of man-made continuous filament synthetic yarns is hydrophobic. The composite web weights between about 20 gsm and about 40 gsm.

Hydroformed composite material and method for making same

A hydroformed composite material includes an expanded spun bonded nonwoven layer having a loft of at least about 1.3 times greater than an original loft of an original unexpanded spun bonded nonwoven web from which the expanded spun bonded nonwoven layer was created, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed composite material includes a formed film layer that includes a plurality of extended cells containing continuous fibers and/or fibrils of the expanded spun bonded nonwoven layer.

Patterned Apertured Webs

A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.

Laminates for absorbent articles and methods of making the same

Three-dimensional laminates and methods for making the same are provided. The three-dimensional laminates may be apertured and may have welds between various substrates. The three-dimensional laminates may be used in absorbent articles, such as diapers and pants, for example, as topsheets, as topsheets and acquisition layers, or as outer cover materials, for example. The three-dimensional laminates may be produced on an absorbent article manufacturing line.

ABSORBENT ARTICLE COMPRISING A TOPSHEET/ACQUISITION WEB LAMINATE

An absorbent article for personal hygiene comprises a longitudinal axis, a transversal axis perpendicular to the longitudinal axis, a topsheet/acquisition web laminate, a liquid impermeable backsheet, and an absorbent core. The absorbent core is located between the topsheet/acquisition web laminate and the backsheet. The topsheet/acquisition web laminate comprises a liquid permeable topsheet and an acquisition web in a face to face relationship. The topsheet/acquisition web laminate comprises three-dimensional protrusions extending from a plane of the topsheet/acquisition web laminate. The acquisition web is a nonwoven fibrous web comprising an upper layer facing towards the topsheet and a lower layer facing towards the absorbent core. The average diameter of the fibers in the upper layer is higher than the average diameter of the fibers in the lower layer.

Absorbent Articles

Absorbent articles comprising material webs are disclosed herein. The material webs described herein can provide a bevy of benefits when utilized in the context of absorbent articles, and such material webs can facilitate the manufacturing of absorbent article.

MULTI-COMPONENT TOPSHEETS HAVING THREE-DIMENSIONAL MATERIALS

The present disclosure is directed to multi-component topsheets having three-dimensional materials. The present disclosure is directed to absorbent articles having multi-component topsheets having three-dimensional materials. The three-dimensional materials may have apertures. The topsheets may have a first material, a second material, and a third material. The first and second materials may be the same and the third material may be different from the first and second materials. The first and second materials may have a lower basis weight than the third material.

Method Of Making Nonwoven Material Having Discrete Three-Dimensional Deformations With Holes In Selected Portions Of The Protrusions
20170259550 · 2017-09-14 ·

Nonwoven materials having discrete three-dimensional deformations therein forming protrusions that extend outward from the first surface of the nonwoven material and wide base openings adjacent to the second surface of the nonwoven material are disclosed. At least some of the three-dimensional deformations may have improved protrusion dimensions after compressive forces are applied on the nonwoven material. In some cases, at least some of the protrusions may have one or more holes therein or completely therethrough. Methods of making the same are also disclosed.

Absorbent article

An objective is to provide an absorbent article that can prevent backflow and can reduce water retention in a front sheet as much as possible. In an incontinence pad 1 for use with a medium or larger volume that absorbs 20 cc or a larger volume of urine, a front sheet 3 is formed by coating a water repellent on a spunlace nonwoven fabric that is made of 100 wt. % of cotton fiber. On a skin facing surface side, in a plan view, recess part lines 20, 21 of a diamond-shaped lattice pattern are formed from many first recess part lines 20 that go along a predetermined inclination angle direction and are formed with a constant gap in the pad longitudinal direction and many second recess part lines 21 that go along the inclination angle direction obtained by reversing the first recess part lines 20 in a width direction by the pad longitudinal direction and are formed with a constant gap in the pad longitudinal direction, partition areas 22 of a diamond-shaped lattice shape partitioned by these recess part lines 20, 21 are arranged adjacently in the longitudinal direction and the width direction. Furthermore, many open holes 10 penetrating through both sides are formed at least at an excretion hole corresponding part H.

Absorbent articles with multi-pieces acquisition layer

An absorbent article having a front side, a back side, a longitudinal axis notionally extending in a longitudinal direction from the middle of the front side to the middle of the back side. The absorbent article has a length L measured along the longitudinal axis. The absorbent article comprises a liquid permeable topsheet on the wearer-facing side, a liquid impermeable backsheet on the garment-facing side, an absorbent core between the topsheet and the backsheet, and an acquisition layer comprising two or more discrete longitudinally-orientated stripes of an acquisition material between the topsheet and the absorbent core. The topsheet forms recesses at the surface of the absorbent article in the gaps between the stripes.
