ABSORBENT ARTICLES COMPRISING GARMENT-FACING LAMINATES
An absorbent article is provided. The absorbent article comprises a liquid permeable topsheet on a wearer-facing side of the absorbent article and a garment-facing laminate on a garment-facing side of the absorbent article. The garment-facing laminate comprises a first nonwoven layer and a second layer joined to the first nonwoven layer. The first nonwoven layer comprises a plurality of apertures. At least 3 of the plurality of apertures in a repeat unit have a different Effective Aperture Area, according to the Aperture Test herein, a different shape, or a different Absolute Feret Angle, according to the Aperture Test herein. The absorbent article comprises an absorbent core disposed at least partially intermediate the liquid permeable topsheet and the garment-facing laminate.
Roofing underlayment with hydrophobic nonwoven core
A roofing underlayment includes a hydrophobic nonwoven core layer that provides enhanced resistance to water infiltration. In addition to the hydrophobic nonwoven core layer, the roofing underlayment includes a coating layer adhered to a surface of the hydrophobic nonwoven core layer, and an exterior surface layer adhered to the coating layer. A roofing system that includes the roofing underlayment is also provided.
Extensible nonwoven fabric
Extensible nonwoven fabrics having improved elongation, extensibility, abrasion resistance and toughness. In particular, embodiments of the invention are directed to extensible spunbond fabrics comprising a polymeric blend of a metallocene catalyzed polypropylene, polyethylene, and a third polymer component.
Shaped nonwovens that exhibit high visual resolution
A nonwoven fabric is disclosed. The nonwoven fabric can include a first surface and a second surface and at least a first visually discernible zone 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, and the first visually discernible zone can exhibit a high visual resolution.
Patterned apertured webs
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 plurality of apertures include a first set of apertures defining a first shape and a second set of apertures defining a second shape. The first shape is positioned within the second shape.
Shaped Nonwovens that Exhibit High Visual Resolution
A nonwoven fabric is disclosed. The nonwoven fabric can include a first surface and a second surface and at least a first visually discernible zone 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, and the first visually discernible zone can exhibit a high visual resolution.
Nonwoven fabric, a laminated fabric, a nonwoven fabric product, a multicomponent fibre, a web, and a method of producing the nonwoven fabric
A nonwoven fabric comprising a meltspun fiber of a lignin compound. Also claimed a laminated fabric comprising the nonwoven fabric, a nonwoven fabric product comprising the nonwoven fabric, a structured multicomponent fiber comprising a lignin compound, a web comprising a meltspun fiber of a lignin compound and a method of producing a nonwoven fabric by forming a web of meltspun fiber comprising a lignin compound and bonding at least a portion of the fiber in the web to form the nonwoven fabric.
Filmless backsheets with good barrier properties
A multilayer nonwoven structure is described where the nonwoven structure comprises at least two spun bond layers and at least one easily meltable layer. The easily meltable layer is located between the at least two spunbond layers. The easily meltable layer is comprised of a polymer having a melting point at least 20° C. less than the melting point of the polymer which comprises the surface of the fibers which comprise the spun bond layer, or is made from a polymer which is readily absorbs some form of radiation. Under bonding conditions, the fibers which make up the easily meltable layer can be melted to form a film, thereby improving bather properties of the nonwoven structure.
Patterned Apertured Webs
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.
Nonwoven Webs With Hydrophobic And Hydrophilic Layers
A nonwoven web for use in an absorbent article is described. The nonwoven web has first and second nonwoven layers. The first nonwoven layer has a first plurality of fibers, an additive disposed, at least in part, on a portion of the first plurality of fibers, a first side and an opposing second side, wherein second side has a plurality of discontinuities. The second nonwoven layer has a second plurality of fibers, a first surface and an opposing second surface, and a plurality of tufts extending through at least a portion of the discontinuities in the first nonwoven layer, wherein the second nonwoven layer is attached to the first nonwoven layer such that at least a portion of the second plurality of fibers are in liquid communication with the first nonwoven layer, wherein the first nonwoven layer is hydrophobic and the second nonwoven layer is hydrophilic.
