A patterned apertured web is disclosed. The patterned apertured web includes a plurality of land areas in the patterned apertured web and a plurality of apertures defined in the patterned apertured web. At least some land areas of the plurality of land areas surround at least some apertures of the plurality of apertures. The patterned apertured web has an Effective Open Area in the range of about 3% to about 30%, according to the Aperture Test herein. The patterned apertured web has a plurality of Interaperture Distances, according to the Aperture Test herein. The Interaperture Distances have a distribution having a median and a mean. The plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape.

An absorbent article is disclosed. The absorbent article includes a core and a chassis. One or more discrete bonding zones bond the core to the chassis, and one or more unbonded zones of the core are not bonded to the chassis, forming a floating core. The core is not elastically coupled with the chassis. A method of making the absorbent article may include selectively bonding the chassis to the core at discrete bonding zones.

A method of forming a three-dimensional laminate for an absorbent article is provided. The method comprises providing a first nonwoven layer, providing a second nonwoven layer, and applying a pre-strain force to the first nonwoven layer or to the second nonwoven layer. The method comprises joining the first nonwoven layer to the second nonwoven layer while the first nonwoven layer or the second nonwoven layer is in a pre-strained condition, and releasing the pre-strain force to form the three-dimensional laminate.
摘要:
An interior body of a disposable diaper includes a liquid-permeable front sheet, a liquid-impermeable back sheet and a liquid-retaining absorbent core. The front sheet has a single sheet including spunbond layers on the front side and back side and a melt blown layer between the spunbond layers. The absorbent core has fiber aggregates and super-absorbent polymer particles. The front sheet is directly bonded to the skin side surface of the absorbent core. The length of the front sheet is longer than the length of the absorbent core, so that the front sheet has extended sections which extend outward in the lengthwise direction from both ends of the absorbent core in the lengthwise direction, while the extended sections are each continuously connected in the transverse direction with the front sheet or back sheet which overlaps with the extended section. The extended sections can directly contact the skin of the wearer.

A sanitary napkin has a facing layer joined to a backsheet, and an absorbent core disposed between the facing layer and backsheet. The facing layer has a first region comprising a plurality of apertures, and a second region comprising a plurality of out-of-plane deformations. The absorbent article provides a visual perception of comfort. In one embodiment, the sanitary napkin also comprises a deep-embossed channel.
摘要:
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.
摘要:
An elastic laminate web is disclosed. The elastic laminate web can be non-apertured or apertured, and comprises a first web, and a second web joined to the first web in a face to face relationship at a plurality of discrete bond sites having an aspect ratio of at least 2. The first and second webs form an interior region therebetween. An elastic material is disposed between the first and second webs. The elastic material is apertured in regions coincident the bond sites, such that the first and second webs are joined through the apertures. The laminate so produced can be stretched in a predetermined direction, such as by incremental stretching, to produce an apertured elastic laminate.
摘要:
Absorbent articles such as sanitary napkins, panty liners, adult incontinence devices, and the like, that have components that are bonded for improved integrity and an unbonded window on their body-facing side for improved acquisition are disclosed. The absorbent articles comprise a topsheet that is fused to an underlying liquid pervious or absorbent layer at a plurality of individual bonded areas. The absorbent articles have an unbonded window that is substantially free of bonded areas, which is surrounded by region of the absorbent article that contain bonded areas.
摘要:
A topsheet for use in body fluid absorptive articles is so improved that collapse and clogging of liquid passages therein may be reliably avoided. The topsheet includes an upper sheet, provided with skin-contacting areas and liquid passages, and a lower sheet provided with skin-non-contacting areas, areas welded to the liquid passages, and exposed areas. The exposed areas are welded to each of the liquid passages around lower openings thereof so as to protect the liquid passage against collapse and clogging. The exposed areas define a skin-contacting surface which rises up into each of the liquid passages without extending above the upper surface of the skin-contacting areas. The upper sheet cooperates with the lower sheet to define cavities extending in the direction of the topsheet thickness.
