Provided are disposable diapers that are easy to manufacture. This problem is solved by a boxer-shorts-type disposable diaper including an outer member having ventral and dorsal outer members and a crotch outer member extending therebetween and to be placed through the crotch of a wearer, and an inner member containing an absorber body and joined to the interior face of at least the crotch outer member, wherein the ventral/dorsal outer members are joined in the middle of the width direction in the crotch-side end to the crotch outer member to form ventral/dorsal seams, respectively, the areas extending along the edges of the leg openings in the ventral/dorsal outer members are stretchable in the width direction, and the areas extending along the edges of the leg openings in the crotch outer member are stretchable in the front-back direction.

A reusable undergarment is disclosed with a multi-layer gusset assembly that is permanently affixed in the undergarment to absorb liquids excreted by a wearer of the undergarment and is reusable after washing. The panty also includes body fabric, elastic trim, and non-wicking hydrophobic thread that is sewn through the trim, which sandwiches the body fabric and gusset assembly. The trim may be a single piece of fabric with a waterproof finish that is folded widthwise to form a hollow channel that redistributes excess liquid at the edge of the gusset assembly without leaking. In some manufacturing processes, a waterproof finish may be applied to the elastic trim, and the edge of the gusset assembly may be positioned offset from a fold-line of the trim when folded widthwise. The shape and positioning of the gusset assembly may be cone-shaped in some embodiments.

A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, and wherein in at least one of the microzones, the first region exhibits a Contact Angle of greater than 90 degrees, as measured by the Contact Angle Test Method detailed herein, and the second region exhibits a Time to Wick of less than 10 seconds, as measured by the Time to Wick Test Method detailed herein.

The present invention relates to an apparatus for deforming a web to created deformed nonwoven which comprises a pair of counter-rotating rolls that form a nip therebetween, the pair of rolls comprising: a first roll comprising a surface, a plurality of protrusions extending radially outwardly from the surface of the first roll, and a plurality of concaves formed inwardly from the surface of the first roll; and a second roll comprising a surface; and a process for producing a deformed web comprising the steps of (a) forming a fibrous web; (b) subjecting the fibrous web to bonding treatment to bond at least part of fibers constituting the fibrous web to obtain a precursor nonwoven; and (c) subjecting the precursor nonwoven to a deformation forming unit comprising an apparatus according to the present invention.

Wound cleaning device having a carrier layer and a wound cleaning layer arranged thereon, designed for holding wound exudate and/or solid wound components and having cleaning threads, the carrier layer and/or the wound cleaning layer being provided with at least one storage material that increases the capacity for holding wound exudate.

A method for making a high topography nonwoven substrate includes generating a foam including water and synthetic binder fibers; depositing the foam on a planar surface; disposing a template form on the foam opposite the planar surface to create a foam/form assembly; heating the foam/form assembly to dry the foam and bind the synthetic binder fibers; and removing the template from the substrate after heating the foam/form assembly, wherein the substrate includes a planar base layer having an X-Y surface and a backside surface opposite the X-Y surface; and a plurality of projection elements integral with and protruding in a Z-direction from the X-Y surface, wherein the projection elements are distributed in both the X- and Y-directions, and wherein the density of a projection element is the same as the density of the base layer.

An AHP is disclosed having a topsheet, a backsheet joined with the topsheet, an absorbent core, disposed between the topsheet and the backsheet, and a poly(acrylic acid)-based superabsorbent polymer (SAP), partly derived from recycled resources. The SAP exhibits defined Saline Flow Conductivity and Absorption Against Pressure values. Methods for making the aforementioned AHP are also disclosed.

The present application discloses novel hot-melt adhesive formulations, with excellent processability, even in processes at high line-speed and at a relatively low temperature, the formulations suitable for strongly bonding substrates that have openings, holes, voids or pores, both macroscopic and microscopic ones, like perforated plastic films, both with bidimensional or tridimensional structure; fibrous substrates, both woven and non-woven; porous plastic films, and the like, all mentioned substrates being widely used for the manufacturing of absorbent hygienic articles. The hot-melt formulations include, as their main or even unique constituent, at least one polymer composition formed by two polyolefins, substantially non-stereospecific, as showed by the low value of their crystallization enthalpy at time zero, the polyolefins having average Number Molecular Weights Mn that do not differ for more than about 6,000 g/mole, being the single average Number Molecular Weights of said polyolefins ranging from about 3,000 g/mole and about 30,000 g/mole.

Water-absorbing resin particles are disposed, the water-absorbing resin particles including: a polymer particle containing a crosslinked polymer having a monomer unit derived from an ethylenically unsaturated monomer including at least one kind of compound selected from the group consisting of (meth)acrylic acid and a salt thereof; and a plurality of inorganic particles disposed on a surface of the polymer particle, in which a proportion of a (meth)acrylic acid and a salt thereof is 70 to 100 mol % with respect to a total amount of monomer units in the crosslinked polymer. In a case where a water absorption speed index I=(value of non-pressurization DW after 10 seconds)×6 [mL/g], and a water absorption speed index II=(value of non-pressurization DW after 3 minutes)/3 [mL/g], a static suction index α calculated by the following formula:

α=(I+II)/2

is 5.0 mL/g or higher.

The invention relates to a nonwoven fabric sheet comprising at least two adjacent layers of spunbonded nonwoven webs, one of which is an elastic layer in the form of a spunbonded nonwoven web comprising elastic fibers formed from a thermoplastic elastomer polymer material. The invention further relates to a method of manufacturing such nonwoven and the use of such nonwoven.
