20100049153 | COMPOSITE SHEET AND ABSORBENT ARTICLE COMPRISING COMPOSITE SHEET - A composite sheet which has a low basis weight, can be prevented from breaking during the production of an absorbent article or in use, and is good to the touch. The composite sheet is a sheet formed by bonding a stretch nonwoven fabric to a nonstretch nonwoven fabric with an adhesive. The stretch nonwoven fabric is bonded in a stretched state to the nonstretch sheet. The stretch nonwoven fabric has, on each side, strip-form sparse regions and strip-form dense regions alternately formed. The sparse regions and dense regions on one side are alternately formed in a second direction so that the dense regions on this side do not overlie the dense regions on the other side. The composite sheet has a maximum breaking strength of 20 N/50 mm or higher. | 02-25-2010 |

20110178489 | DISPOSABLE DIAPER - A disposable diaper having a tensile stress well compatible with a wearer's average body contour including convex and concave and thereby to reduce creating an uncomfortable feeling of tightness against the wearer. The disposable diaper including a front waist region that is divided into a first elastic zone extending in the transverse direction along a peripheral edge of the waist-opening, a second elastic zone lying next to the first elastic zone and extending in the transverse direction and a third elastic zone lying next to the second elastic zone extending in the transverse direction between the second elastic zone and the crotch region and the rear waist region is divided into a fourth elastic zone extending in the transverse direction along the peripheral edges of the waist-opening, a fifth elastic zone lying next to the fourth elastic zone and extending in the transverse direction and a sixth elastic zone lying next to the fifth elastic zone and extending in the transverse direction between the fifth elastic zone and the crotch region. The correlation among values of the tensile stress in the elastic zones can be represented by the sixth elastic zone>the second elastic zone>the third elastic zoneā§the fifth elastic zone>the first elastic zone and the fourth elastic zone. | 07-21-2011 |
20120022486 | ABSORBENT ARTICLE AND COMPOSITE SHEET - The present invention provides an absorbent article having a composite sheet with a plurality of gathers on an inner surface facing a wearer's body, which fits and adheres comfortably to the wearer's skin. The composite sheet is provided which includes a stretchable non-woven fabric which expands and contracts in at least one direction, a non-stretchable non-woven fabric, a junction which binds intermittently the stretchable non-woven fabric to the non-stretchable non-woven fabric in the stretching direction, and a plurality of gathers which is formed by loosening a unbounded area of the non-stretchable non-woven fabric in a contracted state, and is arranged along a direction intersecting the stretching direction, in which an apex of each gather does not reach the neighboring gather when the gathers lean to one side of the stretchable direction. | 01-26-2012 |
20120022488 | WEARING ARTICLE - A wearing article has a chassis and leg elastic members of a flat band shape that are attached to the chassis along leg side edges thereof. The chassis has regions each of which overlaps one of the leg elastic members and includes at least one series of depressions extending along the respective leg side edge. | 01-26-2012 |
20120029460 | DISPOSABLE WEARING ARTICLE - A disposable wearing article includes, in an elastic region in a periphery of at least a waist- or leg-opening, an elastic band formed of a fibrous non-woven fabric which is elastically contractible and has a plurality of first gathers extending in a length direction so as to undulate in a width direction thereof. | 02-02-2012 |
20120035564 | PULL-ON ARTICLE - A pull-on article comprises a chassis including a first waist region, a second waist region and a crotch region between the first and second waist regions. The article is shaped into a pull-on having a waist and a pair of leg openings by weld-bonding side edges of the first and second waist regions. The waist and leg openings are respectively provided along respective edged defining the waist and leg openings with waist and leg elastic members which are respectively formed into a tape shape having a relatively width dimension. The first and second waist regions, and the leg and waist elastic members are respectively formed of a fibrous non-woven fabric including at least thermoplastic fibers wherein the leg and waist elastic members include at least elastically extendible fibers as the thermoplastic fibers. | 02-09-2012 |
20130060220 | DISPOSABLE WEARING ARTICLE - The present invention provides a disposable wearing article adapted to inhibit sweating and an uncomfortable stuffiness. Front and rear waist regions of a disposable wearing article have inner surfaces thereof at least partially formed of elastic sheets. The elastic sheets are made of a mixture of elastic fibers and inelastic fibers and formed with ridges and grooves. The elastic sheets have a thickness in the ridges repetitively reduced and restored as the elastic sheets repeat elastic stretch and contraction in the waist circumferential direction. | 03-07-2013 |
20140102618 | METHOD FOR MANUFACTURING STRETCH SHEET - A method for manufacturing a stretch sheet draw a nonwoven fabric conveyed in a continuous state by teeth formed on an outer circumferential surface of a pair of rotating rollers by passing the nonwoven fabric through a gap between the rotating rollers meshing with each of the teeth. The method includes a step of joining a first end of the first nonwoven fabric roll and a second end of the other nonwoven fabric roll through a joint portion. The joint portion is arranged intermittently in a cross direction that crosses the conveyance direction. | 04-17-2014 |
