Bonding apparatus and method
The present disclosure relates to methods and apparatuses for mechanically bonding substrates together. The apparatuses may include a pattern roll including a pattern element protruding radially outward. The pattern element includes a pattern surface and includes one or more channels adjacent the pattern surface. The pattern roll may be positioned adjacent an anvil roll to define a nip between the pattern surface and the anvil roll, wherein the pattern roll is biased toward the anvil roll to define a nip pressure between pattern surface and the anvil roll. As substrates advance between the pattern roll and anvil roll, the substrates are compressed between the anvil roll and the pattern surface to form a discrete bond region between the first and second substrates. As such, during the bonding process, some yielded substrate material flows from under the pattern surface and into the channel to form a channel grommet region.
ABSORBENT ARTICLE
An absorbent article comprising a top-surface sheet 3, a back-surface sheet 2, and absorber 4 interposed between, and a pair of left and right side sheets 7 over an entire length on both side portions of a skin-contact surface side. An inner side in a width direction of each of the side sheets 7 is folded back in the width direction to be laminated in a plurality of layers. A laminated portion 8 of the side sheets 7 includes lower layer side embossed portions 9 for joining the bottom layers of the side sheets 7 and a top-surface sheet 3, and skin-side embossed portions 10 obtained by integrally denting the side sheets 7 of the laminated portion 8 from the skin-contact surface side. The lower-layer-side embossed portions 9 and the skin-side embossed portions 10 are formed in different plane patterns. The absorbent article suppresses deterioration of touch to the skin and obtains good wearing feeling while ensuring sufficient joining strength in a joining portion of side sheets.
Disposable absorbent lift device
The present invention relates to a disposable absorbent pad comprising multiple layers. In particular, the absorbent pad of the present invention maintains skin dryness by absorbing moisture while preventing leakage to the skin or the bed linens, allowing air circulation at the surface of the patient's skin to prevent heat buildup, and is strong enough to allow the patient to be repositioned, even when the pad is wet. In a particular embodiment the first layer is comprised of a fluid-permeable, porous material, the second layer is disposed under the first layer and is comprised of at least one super absorbent material, and a base layer disposed under the second layer.
Apertured webs and methods for making the same
Patterned apertured webs are provided. The patterned apertured webs include a plurality of land areas and a plurality of apertures defined in the patterned apertured webs. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured webs have an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test.
THREE-DIMENSIONAL SUBSTRATE AND ABSORBENT ARTICLES COMPRISING THE SAME
The present disclosure is directed to a three-dimensional substrate comprising a first layer and a second layer intermittently bonded to the first layer, and comprising a first longitudinal edge and a second longitudinal edge, wherein the three-dimensional substrate comprises a first region longitudinally extending along the first longitudinal edge and having a first peel force, a second region longitudinally extending along the second longitudinal edge and having a second peel force, and a third region located between the first and second regions in a transversal direction and having a third peel force, and wherein at least one of the first peel force and the second peel force is higher than the third peel force or, the first peel force and the second peel force are higher than about 0.15N/50.8 mm; and an absorbent article comprising the same.
Diaper structure with enhanced tactile softness attributes
A diaper structure with enhanced softness attributes is disclosed. The diaper structure may include an innermost layer formed of a first nonwoven web, and an outermost layer formed of a second nonwoven web. The first and second nonwoven webs may have a combined basis weight of at least about 30 gsm. The ratio of the first web basis weight to the second web basis weight may range from 30/70 to 70/30.
FLEXIBLE AND COMPLIANT MECHANICALLY-DEFORMED NONWOVENS FOR USE IN ABSORBENT ARTICLES
A mechanically deformed nonwoven comprising a plurality of protrusions extending outwardly from a first surface of the nonwoven and having openings c corresponding to the protrusions in a second surface of the nonwoven. The nonwoven has a Horizontal Bending Drop at 100 mm of at least 75 mm and a Z-Compliance Index of at least 50 mm.sup.3/N. The nonwoven can be used in absorbent articles such as diapers as an acquisition layer between the absorbent core and the backsheet and/or as a masking layer between an absorbent layer core and the backsheet.
Breathable and microporous thin thermoplastic film
Breathable, thermoplastic films, laminates, and methods of making films having a basis weight less than or equal to 15 gsm and a water vapor transmission rate of at least about 500 grams H.sub.2O/24-hour/m.sup.2, wherein the film has a ratio of the MD load at break to the CD load at break of less than about 10, and at least one of a machine-direction notched Elmendorf tear strength of at least about 5 g or a machine-direction notched trapezoidal tear strength of at least about 15 g.
Nonwoven fabric comprising a high loft spunbond layer
The invention relates to a fabric comprising at least one high loft spunbond nonwoven layer having crimped multicomponent fibers, wherein a first component of the multicomponent fibers comprises a first polymer A and a second component of the multicomponent fibers comprises a blend of the first polymer A and a second polymer B, wherein the melt flow rate of polymer A is at least 25% higher than the melt flow rate of polymer B and wherein the second component comprises at least 40 wt.-% of polymer B.
Apertured webs and methods for making the same
A patterned apertured web includes a plurality of first arrays forming a first zone in the patterned apertured web. At least some of the first arrays include a first plurality of land areas and a first plurality of apertures. At least some of the first plurality of land areas surround at least some of the first plurality of apertures. The first plurality of apertures of the first zone have a plurality of Interaperture Distances, according to the Aperture Test. The Interaperture Distances of the first zone have a first distribution having a first mean and a first median. The first mean is greater than the first median by at least 4%.
