APPARATUSES AND METHODS FOR MAKING ABSORBENT ARTICLES WITH ELASTOMERIC LAMINATES
The present disclosure relates to methods and apparatuses for making elastomeric laminates with deactivated regions that may be used as components of absorbent articles. The methods and apparatuses may be configured with a pattern roll and a pressing surface adjacent the pattern roll. The pattern roll may include a bonding surface and a protuberance. As the pattern roll rotates, first and second substrates are welded together between the bonding surface and the pressing surface to create bonds between the first and second substrates. As the pattern roll continues to rotate, the first and second substrates and one or more stretched elastic strands are compressed between the pressing surface and the protuberance to sever the one or more stretched elastic strands to create deactivated regions in the elastomeric laminate. The processes and apparatuses may be configured to help prevent ends of the severed elastic strands from retracting in an uncontrolled fashion.
Crimped fiber spunbond nonwoven webs/laminates
An article includes a chassis having a topsheet, backsheet and an absorbent core disposed between the topsheet and backsheet; and an ear joined to the chassis. The ear includes a ring-rolled laminate having a first nonwoven web and an elastomeric film; wherein the first nonwoven web has a crimped spunbond fiber nonwoven web.
Wearable article having elastic belt
Disclosed is a wearable article continuous in a longitudinal direction and a transverse direction comprising a center chassis and a ring-like elastic belt comprising a front belt and a back belt; the front and back belt each formed by a laminate comprising a plurality of elastic bodies running in the transverse direction, an inner sheet, an outer sheet, and an outer sheet fold over; wherein at least one of the front belt and the back belt has: a) the longitudinal edge of the center chassis being distal than, preferably at least about 10 mm distal than, the outer sheet fold over proximal edge; b) in the left and right side panels: b-1) at least one elastic body, preferably at least two elastic bodies, disposed between the outer sheet and the outer sheet fold over in regions where the inner sheet does not overlap; b-2) one to no more than about 8 elastic bodies disposed between the outer sheet and inner sheet in regions where the outer sheet fold over overlaps in the thickness direction, and b-3) the remaining elastic bodies disposed between the outer sheet and the inner sheet in regions where the outer sheet fold over does not overlap in the thickness direction, wherein any elastic body disposed between the outer sheet and the inner sheet is disposed at least about 5 mm away from the inner sheet distal edge.
Elastomeric laminate with soft noncrimped spunbond fiber webs
An absorbent article includes a first waist region, a second waist region, and a crotch region disposed between the first and second waist regions. The article also includes a chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet; and an ear joined to the chassis. The ear includes a laminate formed from a first nonwoven and second nonwoven and an elastomeric material sandwiched between said first and second nonwovens. The laminate further includes a plurality of ultrasonic bonds.
Absorbent article and method for producing same
An absorbent article includes a novel design printing portion suitable for a stretchable region. An absorbent article has an elastic film stretchable structure, in which an elastic film is stacked between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded together directly or through the elastic film by a large number of sheet bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region. The stretchable region is contracted in a stretchable direction by a contraction force of the elastic film is extensible in the stretchable direction. A design printing portion is provided in a portion located in the stretchable region in the elastic film.
Wearable article having elastic belt
Disclosed is a wearable article continuous in a longitudinal direction and a transverse direction comprising a center chassis and a ring-like elastic belt comprising a front belt and a back belt; the front and back belt each formed by a laminate comprising a plurality of elastic bodies running in the transverse direction, an inner sheet, an outer sheet, and an outer sheet fold over, wherein at least one of the front belt and the back belt has: a) the longitudinal edge of the center chassis distal than, preferably at least about 10 mm distal than, the outer sheet fold over proximal edge, and b) in the left and right side panels: b-1) at least one elastic body, preferably at least 2 elastic bodies, disposed between the outer sheet and the outer sheet fold over in regions where the inner sheet does not overlap in the thickness direction; and b-2) the remaining elastic bodies disposed between the outer sheet and the inner sheet in regions where the outer sheet fold over does not overlap in the thickness direction.
PANTS-TYPE DISPOSABLE DIAPER AND METHOD FOR MANUFACTURING PANTS-TYPE DISPOSABLE DIAPER
A disposable diaper includes: a belt portion and an absorbent main body. The belt portion includes an exterior sheet and an elastic film that is stretchable at least in the lateral direction, the exterior sheet and the elastic film are joined to each other at joining portions, the elastic film includes a stretchable layer and a low stretchable layer, the stretchable layer stretches and contracts in the lateral direction, and the low stretchable layer is overlaid on the stretchable layer and has lower stretchability than the stretchable layer. In at least one of the joining portions, the low stretchable layer is continuous, and in at least a part of a periphery portion of the at least one of the joining portions, the stretchable layer and the low stretchable layer are separated from each other.
ABSORBENT ARTICLES WITH CURVED ELASTICIZED LAMINATES
Absorbent articles having curved elasticized laminates and apparatuses and methods for forming such articles are disclosed. In one embodiment, an absorbent article having a front waist region, a crotch region, and a rear waist region may comprise a chassis comprising bodyside liner, an outer cover, an absorbent body. The article may further comprise a pair of elasticized laminates attached to the chassis to form elasticized leg cuffs. Each of the first pair of elasticized laminates may comprise a laminate material forming a fold and an elastomeric member disposed between the laminate material. Each of the first pair of elasticized laminates may be attached to the chassis such that the fold comprises an outermost longitudinal edge of the article throughout the crotch region, and the fold and the elastomeric member of each of the elasticized laminates may extend in a curving manner throughout the crotch region.
