A composite includes a first substrate and a second substrate joined in a bonding region, wherein the first substrate comprises a first Peak Force Tensile Strength and the second Peak Force Tensile Strength. The first Peak Force Tensile Strength is greater than or equal to the second Peak Force Tensile Strength. The bonding region has a Bond Density of about 10% to about 22%; and a Composite Tensile Strength at Peak Force that is within about 15% of the second Peak Force Tensile Strength.

An underpants-type disposable diaper wherein the end portions of elastic members are kept from being drawn in, and the bonding strength in side sealed portions is kept from deteriorating. The diaper has outer member defining front and back body sections, wherein side portions of the outer member in the front and back body sections are joined to form side sealed portions, which produce a waist opening and a pair of leg openings. The front and/or back body sections, are provided with a tortuous elastic member extending with curvature from one to the other of the side sealed portions, and bonded thereto with adhesive. The amount of adhesive applied to a zone neighbouring the inner zone of each side sealed portion is larger than that applied to the outer zone of each side sealed portion.

The inventors have discovered hot melt adhesive compositions that can be formulated to have a high percentage of environmentally conscious components and still provide performance over a broad temperature range.

The invention features a hot melt adhesive composition including from 5% by weight to 50% by weight of a styrene block copolymer, from 15% by weight to 75% by weight of a bio-based tackifying agent, and from 5% by weight to 40% by weight of an aliphatic plasticizer having a cyclo-aliphatic content of no greater than 1% by weight as tested by .sup.1H-NMR Spectroscopy, wherein said hot melt adhesive composition has an environmentally conscious component content of at least 50% by weight.

A multi-layered wound dressing including a fibrous absorbent layer for absorbing exudate from a wound site. The wound dressing also includes a support layer configured to reduce shrinkage of at least a portion of the wound dressing.

A system for manufacturing elastic strand nonwoven panels including an unwind module, a lamination module and a folding module. Elastic strand material is fed from cores disposed on the unwind module through rollers towards the lamination module, where the elastic strand material is attached to a nonwoven web to form an elastic strand nonwoven web. At the folding module, the elastic strand nonwoven web is folded over itself by operation of plates underneath which the elastic strand nonwoven web is fed under tension.

Disclosed is a wearable article comprising a main body and a ring-like elastic belt comprising an outer cover layer, a backsheet, a front belt artwork region; and a back belt artwork region; and wherein one or both of the front and back belt artwork regions comprises a belt artwork; a transitional region on the front waist panel and the back waist panel where the outer cover layer exists; and a crotch artwork region on the crotch panel comprising a crotch artwork; wherein at least some of the belt artwork and some of the crotch artwork are printed on the backsheet, wherein when the opacity of the outer cover layer is OC and the opacity of one or both of the front belt and the back belt comprising the belt artwork is OB, respectively, the difference between OC and OB is less than about 20%.

An absorbent article comprising: a liquid permeable topsheet, a liquid impermeable backsheet, and an absorbent core positioned between said topsheet and backsheet, wherein the absorbent core comprises an absorbent material, said absorbent material comprising cellulose fibers and/or superabsorbent polymers, and wherein said absorbent material is contained within at least one core wrap substrate enclosing said absorbent material, and wherein a top layer of said core wrap is adhered to a bottom layer of said core wrap by a first adhesive to form one or more channel forming areas substantially free of said absorbent material, wherein said top layer comprises said first adhesive arranged to define a first adhesive area and said bottom layer comprises a second adhesive arranged to define a second area, wherein said first adhesive area is greater than said second adhesive area, and wherein said first and second adhesive areas comprise one or more adhesive stripes, wherein at least one of said adhesive stripes of the first adhesive area overlap said channel forming areas.

A composite web including a first continuous web having a first face and a second face; the first web includes a molded portion having at least one protrusion, at least partly delimited by a base portion, on the first face; the composite web includes a segment of a second continuous web joined to the second face of the first web at least at the base portion.

Described herein is an absorbent article. The absorbent article includes an assembly of components and an adhesive composition joining at least two of the assembly of components together. The adhesive composition includes from about 50 wt. % to about 80 wt. % of one or more copolymers and a blend of one or more heterophase copolymers. The one or more copolymers include from about 30 mole % to about 70 mole % of monomer units selected from ethylene. 1-butene, and mixtures thereof. The one or more copolymers also include from about 30 mole % to about 70 mole % of propene monomer units. The adhesive composition is free of polyisobutylene and has a viscosity of from about 2,000 mPa.Math.s to about 11,500 mPa.Math.s at 150° C.

A method for forming a wearable absorbent article may comprise forming, by a system, an absorbent chassis comprising an absorbent core, a first lateral end, a second lateral end, and a length in a longitudinal direction extending between the first lateral end and the second lateral end. The method may further comprise forming, by the system, a reusable belt, and attaching, by the system, the belt to the absorbent chassis via at least one temporary fastener component formed on at least one of the absorbent chassis or the belt, resulting in formation of a wearable absorbent article unit.
