摘要： A film for use in an absorbent article includes a first side and a second side opposite the first side, and a plurality of apertured protuberances arranged in a pattern having 60 to 120 protuberances per linear inch in at least one direction. Each of the protuberances includes a continuous sidewall extending from the first side. The second side has a plurality of apertures aligned with the plurality of apertured protuberances and land areas in between the apertures. The film has a melt index of at least about 8 g/10 min, and an air permeability of at least about 80 m3/m2/min.

摘要： A nonwoven composite that has a dimension in a machine direction and a cross-machine direction is provided. The composite comprises a nonwoven facing positioned adjacent to an elastic film. The nonwoven facing contains a spunbond web that is formed by necking a base spunbond web. The base spunbond web includes a plurality of fibers generally oriented in the machine direction and exhibiting a machine direction tensile strength and cross-machine direction tensile strength. The ratio of the machine direction tensile strength to the cross-machine direction tensile strength is about 4:1 or more.

摘要： An underpants-type disposable diaper has a display sheet containing a resin film between an inner member and at least one of a front side outer member and a back side outer member. A cover nonwoven fabric is provided with a plurality of holes having intervals and penetrating a front and a back is interposed from at least a crotch side edge of an outer member overlapping the display sheet to a side of a waist opening between the display sheet and a liquid impervious sheet. An internal surface and an external surface of the cover nonwoven fabric are bonded to facing surfaces, respectively, through a hot melt adhesive. Compatibility between prevention of deterioration of appearance of the display sheet and prevention of a decrease in air permeability is achieved.

摘要： In a dot pattern, both sufficient strength during the use of a diaper and the ease of tearing can be achieved, while inhibiting sticking of fiber waste of a non-woven fabric in the sealing device. The problems can be solved by the underpants-type disposable diaper characterized by a side seal section 13 is formed in a dot pattern in which a plurality of rows of dot-shaped welded parts 13s, 13b, disposed with intervals in a vertical direction, are disposed in a transverse direction, and non-welded parts 13n, disposed all over in the transverse direction, are disposed on both sides of each welded part 13s, 13b, in the vertical direction; the side seal section 13 has at least partly in the vertical direction a non-densely welded region LD and a densely welded region HD; and each welded part 13b in the densely welded region HD is larger in area than each welded part 13s in the non-densely welded region LD.

摘要： The present invention discloses and claims an absorbent article which utilizes an absorbent portion that includes superabsorbent yarn as part of the absorbent portion, such that liquid is wicked to the perimeter or select regions of the absorbent portion, or the perimeter of the absorbent article itself, taking full advantage of either the depth, width, length or combination of dimensions of the absorbent portion, or absorbent article. The superabsorbent yarn can be one or more of several types, including encapsulated yarn, multilayered encapsulated yarn, coated yarn and sliver-formed yarn as long as such yarn includes at least two components, those being a superabsorbent polymer and a second material which promotes distribution of liquid along the yarn length. In alternatives of the invention, such absorbent article utilizing the superabsorbent yarn provides passive visual signals to consumers, of article saturation levels prior to leakage.

摘要： [PROBLEM] To prevent an overlapping portion formed by overlapping the side portions of an enveloping sheet for enveloping an absorber from opening, and to enable a fluid to smoothly diffuse in the absorber.[SOLUTION] An incontinence pad (1) includes a permeable front-side sheet (3), a back-side sheet (2), an absorber (4) enveloped by an enveloping sheet (5) and disposed between the permeable front-side sheet and the back-side sheet, and bilaterally-symmetric embossments (10) formed in a front surface of the permeable front-side sheet (3). An overlapped portion (9) is formed on a front side of the absorber (4) along a longitudinal direction by overlapping the side portions of the enveloping sheet (5). The longitudinal length of one of the bilaterally-symmetrical embossments (10) that overlaps the overlapped portion (9) is greater than or equal to 70% of the longitudinal length (LS) of the overlapped portion (9), and the lateral length of one of the bilaterally-symmetrical embossments is greater than or equal to 10% of the lateral length (WS) of the overlapped portion (9). An adhesive for bonding the side portions of the enveloping sheet (5) is not applied to a longitudinal area of the overlapped portion (9) where the embossment (10) is formed.

摘要： A process for making a hydrophilic nonwoven structure comprising: forming a nonwoven structure comprising fibers; and exposing the nonwoven structure to an atmospheric plasma comprising an inert gas and a substance having a polar group and which can be vaporized or made into an aerosol and which forms a free radical upon exposure to a dielectric barrier discharge is provided. Also provided are nonwoven structures produced thereby and articles containing the nonwoven structures.
