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.
THREE-DIMENSIONAL SUBSTRATE COMPRISING A TISSUE LAYER
A three-dimensional substrate has a first surface, a second surface, land areas and comprises three-dimensional protrusions extending outward from the second surface of the three-dimensional substrate. The three-dimensional protrusions are surrounded by the land areas. The three-dimensional substrate is a laminate comprising at least two layers in a face to face relationship. The second layer comprise a tissue layer facing outward from the second surface of the three-dimensional substrate. The tissue layer comprises at least 80% pulp fibers by weight of the tissue layer.
Method Of Making Nonwoven Material Having Discrete Three-Dimensional Deformations With Holes In Selected Portions Of The Protrusions
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 ARTICLE
An absorbent article (1) comprising a top sheet (2), a back sheet (3) and an absorbent body (11) provided therebetween, wherein: the absorbent body (11) comprises plural layers of a sheet member and has a sealed part (14) in which the sheet members are bonded to each other and a non-sealed part (15) in which the sheet members are not bonded to each other, and an absorbent material is disposed in the non-sealed part (15), thereby forming an absorption area (16); the absorbent material disposed in the absorption area (16) contains an absorbent polymer in a proportion of 50 mass % or more the absorption area (16) is provided in a stripe shape extending in the front-rear direction; concave grooves (17) are formed from the top sheet (2) to the absorbent body (11) on one side and the other side in the width direction on a skin facing side of the absorbent article (1); and the concave grooves (17) are arranged such that the entire concave groove (17) overlaps with the absorption area (16) and end portions in the front-rear direction of the concave groove (17) are curved inward in the width direction.
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.
Absorbent articles with improved topsheet dryness
Absorbent articles having three-dimensional, apertured, liquid permeable topsheets, acquisition materials, liquid permeable backsheets, and absorbent cores are disclosed. The absorbent articles provide improved topsheet dryness, reduced collagen rewet, and improved modified fluid acquisition.
THREE-DIMENSIONAL NONWOVEN MATERIALS AND METHODS OF MANUFACTURING THEREOF
Three dimensional nonwoven materials and methods of manufacturing such materials are disclosed. In one embodiment, a method can include providing a precursor web that includes a plurality of fibers and transferring the precursor web to a forming surface having a plurality of forming holes. The method can also include directing a plurality of pressurized fluid streams of entangling fluid in a direction towards the precursor web on the forming surface to move at least some of the fibers into the plurality of forming holes to create a fluid entangled web. The method can further include removing the fluid entangled web from the forming surface such that the at least some of the fibers moved into the plurality of forming holes provide a plurality of nodes. The plurality of nodes can have an anisotropy value greater than 1.0 as determined by the Node Analysis Test Method.
Absorbent article
A compressed groove point (16) where compressed grooves (12) formed bilaterally and symmetrically on both sides of a center line (CL) in a lengthwise direction of a sanitary napkin (1) or lines extended from center lines of the compressed grooves (12) intersect with each other at a position corresponding to a front end (31) of a intergluteal cleft of a wearer is formed, and a right and left pair of outline inflection points (17) is formed in an outline of a rear end of the sanitary napkin (1) formed into a bilateral and symmetric wavelike shape. Easy deformation parts (18) that facilitate generation of a deformation in a transverse direction of the sanitary napkin (1) and are formed of the compressed grooves that become base edges of the deformation, are provided on or in the vicinity of two virtual lines (S) connecting the compressed groove base point (16) to the outline inflection points (17) on right and left sides, respectively, such that a distance between the two virtual lines (S) gradually increases toward a rea side.
