Abstract: Disposable article that include fibers formed from compositions comprising thermoplastic polymers and waxes are disclosed, where the wax is dispersed throughout the thermoplastic polymer.

Abstract: The present invention relates to a process of forming a soft bulky nonwoven web from a batt using thermobonding and to a soft bulky nonwoven web with a bond impression pattern and shape. The process comprises several steps including feeding a batt to a nip between first and second surface of first and second roller, where at least the first of the surfaces comprises spaced apart bonding protrusions surrounded by recessed areas. The bonding protrusions and the bond impression shape in the web exhibit a ratio of the greatest measurable width to the greatest measurable length of at least 1:2.5 and the perimeters thereof comprise a convex portion. The bonding protrusions are symmetric and/or have a certain angle to the machine direction.

Abstract: The present disclosure, in part, relates generally to an absorbent article to be worn about the lower torso. The absorbent article comprises a chassis comprising a topsheet, a backsheet, an absorbent core disposed between the topsheet and the backsheet, and a pair of longitudinal barrier cuffs attached to the chassis. Each of the longitudinal barrier cuffs is formed of a web of material. The web of material comprises a first nonwoven component layer comprising fibers having an average diameter in the range of about 8 microns to about 30 microns, a second nonwoven component layer comprising fibers having an average diameter of less than about 1 micron, and a third nonwoven component layer comprising fibers having an average diameter in the range of about 8 microns to about 30 microns. The second nonwoven component layer is disposed intermediate the first nonwoven component layer and the third nonwoven component layer.

Abstract: The present invention refers to a multilayered nonwoven web having layers of different color. The nonwoven web is pattern bonded to obtain bonded areas have a different color versus the unbonded areas.

Abstract: An article having as a component a section of nonwoven web formed predominately of polymeric fibers is disclosed. The section of nonwoven web may have a pattern of consolidating bonds impressed on the surface. The bonds may have at least one bond shape; and the bond shape may have a perimeter with a greatest measurable length and greatest measurable width. The perimeter may have a convex portion and an aspect ratio of length/width of at least 2.5. Other features may be imparted relating to the density and orientations of the bonds relative machine and cross directions of the web. The bond shape reflects the shape of a corresponding bonding protrusion on a bonding roller. It is believed that the shape, density and/or orientation of the bonding protrusions affect air flow through the bonding nip in a way that may be utilized to enhance loft of the resulting bonded nonwoven web.
