Absorbent article having waist gasketing element
An absorbent article for wearing about the lower torso of a wearer includes a first waist region having a first waist edge, a second waist region having a second waist edge, and a crotch region disposed between the first and second waist regions. The article further includes a first longitudinal edge, a second longitudinal edge, and a chassis having a topsheet, a backsheet, and an absorbent core disposed between the topsheet and backsheet. A waist gasketing element is joined to the chassis and disposed in one of the first waist region or the second waist region. The waist gasketing element has a top layer and a bottom layer, an inboard lateral edge and an outboard lateral edge, and first area, A1. The top layer is bonded to the bottom layer in a closure bond region by a closure bonding technique. The closure bond region has an aggregate closure bond area, BA, which is at least about 10% of the first area, A1.
Shaped Nonwoven
A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, wherein the intensive property is one or more of thickness, basis weight, or volumetric density, and wherein the first surface has a TS7 value different than a TS7 value of the second surface.
BREATHABLE ABSORBENT ARTICLE
An absorbent article including a non-woven substrate of one or more layers of meltblown fibers and a first layer of spunbond fibers and a second layer of spunbond fibers. The absorbent article further includes an absorbent core comprising at least one of fibers or a superabsorbent polymer. At least one of the non-woven substrate or the absorbent may be treated with an alcohol repellency (AR) treatment.
Apertured nonwoven
An apertured nonwovens having a first nonwoven layer is described. The first nonwoven layer includes cellulose-based fibers and a plurality of apertures, wherein the plurality apertures have a minimum aperture distance between two adjacent apertures which has a relative standard deviation no greater than about 40%, as measured according to the Aperture Quality Test. The apertures have an aperture size no greater than about 2.2 mm.sup.2 and have an occlusion no greater than about 9%, as measured according to the Aperture Quality Test, or the apertures have an aspect ratio no greater than about 2.5 as measured according to the Aspect Ratio Test.
Garment-like absorbent articles
Garment-like absorbent articles are disclosed. The garment-like absorbent articles may include two nonwoven components that have coordinating and/or substantially similar repeat patterns of apertures and/or bonds. The two nonwoven components may also have certain repeat unit areas, repeat unit width, and repeat unit lengths to aid in softness and to provide improved aesthetic appearance to consumers.
Shaped nonwoven
A nonwoven fabric. The nonwoven fabric can include a first surface and a second surface and a visually discernible pattern of three-dimensional features on one of the first or second surface. Each of the three-dimensional features can define a microzone comprising a first region and a second region. The first and second regions can have a difference in values for an intensive property, wherein the intensive property is one or more of thickness, basis weight, or volumetric density, and wherein the first surface has a TS7 value of less than about 15 dB V2 rms.
PANT-TYPE WEARABLE ARTICLE
A wearable article has a front elastic belt region, a back elastic belt region, a crotch region, a waist opening, and two leg openings. Each elastic belt region has a laminate having an inner sheet, an outer sheet, and an elastic member. The elastic member is bonded continuously for at least about 10 mm in the direction of stretch in a region adjacent side edges of the elastic belts. At least the outer sheet includes a first repeating pattern of apertures having a Longitudinal Orientation. Each aperture has an aspect ratio of no more than 3, a transverse dimension APT of at least 0.4 mm, and a longitudinal dimension APL. APT is at least 10% greater than APL. The apertures are spaced apart with a longitudinal pitch DF2 of no more than 5 mm and a transverse pitch DF1. APL is not larger than 50% of DF2.
Nonwoven thermal bonding pattern with low fuzz
A nonwoven comprising a pattern of thermal bonds with anti-fuzz properties according to at least three and preferably all four of the following conditions: a) the pattern comprises thermal bonds disposed in parallel rows having a pitch angle (P) of from 0.5 to 15 relative to the machine direction or the cross-machine direction; and/or b) the bonding area of all the thermal bonds ranges from 17% to 30% of the area of the nonwoven, and/or c) the pattern comprises larger bonds and smaller bonds having different individual area, and/or d) the pattern comprises elongated bonds having different major directions.
Highly Extensible Nonwoven Webs and Absorbent Articles Having Such Webs
A highly extensible nonwoven web is provided. The highly extensible nonwoven web may include continuous multi-component fibers. The continuous multi-component fibers may include polypropylene, wherein the polypropylene has a crystallinity of less than about 41%. The polypropylene may have a melting temperature of less than about 161 C. The highly extensible nonwoven web may define a plurality of apertures. The apertures may be patterned. The highly extensible nonwoven web may form a portion of an absorbent article.
ABSORBENT ARTICLE
An absorber, a liquid impervious sheet covering a back surface side of the absorber and having air permeability, and a cover nonwoven fabric covering a back surface side of the liquid impervious sheet are provided. The cover nonwoven fabric has a large number of holes penetrating the front surface and back surface at intervals in a region overlapping with the liquid impervious sheet. Edge portions of the holes bend-up toward a front surface side. In a region having the holes in the cover nonwoven fabric, rows of the holes, which are aligned in the front-back direction at intervals in the front-back direction narrower than the dimension in the front-back direction of each of the holes, are repeatedly formed at predetermined intervals in the width direction, and the interval of the adjacent two holes in the width direction is wider than the dimension in the front back-direction of the hole.
