A method, apparatus, and system for reticulating an adhesive on a workpiece. The workpiece may be perforated with a plurality of passages that extend through a first side to a second side. To reticulate an adhesive on the first side of a workpiece, a flow of heated fluid is provided through a nozzle. The nozzle provides the fluid at a first pressure to a first group of the perforations. Once the temperature at the first side of the workpiece reaches a specified range, the fluid pressure may be increased or otherwise set in order to clear the perforations by forcing the adhesive out of or away from each of the perforations. Temperature of the adhesive, pressure within the nozzle, and/or light passage through the perforations may be monitored for logical control or quality assurance.

A hydroformed composite material includes an expanded spun bonded nonwoven layer having a loft of at least about 1.3 times greater than an original loft of an original unexpanded spun bonded nonwoven web from which the expanded spun bonded nonwoven layer was created, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed composite material includes a formed film layer that includes a plurality of extended cells containing continuous fibers and/or fibrils of the expanded spun bonded nonwoven layer.

A hydroformed expanded spun bonded nonwoven has a first substantially planar surface on one side thereof and a second surface on an opposite side thereof. The second surface includes a plurality of protuberances in a pattern. The hydroformed expanded spun bonded nonwoven web has an average loft of at least about 1.3 times greater than an original average loft of an original unexpanded spun bonded nonwoven web from which the hydroformed expanded spun bonded nonwoven web was created and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed expanded spun bonded nonwoven web includes bicomponent fibers combining a polymer with PLA in a ratio of polymer/PLA within a range of about 20/80 to 80/20.

The foam and fiber composite can provide an absorbent article with improved dryness and an improved liquid distribution capability. The foam and fiber composite can be formed from at least two materials. The first material is an open cell foam material and the second material is a fibrous material. A plurality of the fibers forming the fibrous material can be fluid inserted into the open cell foam material thereby forming the foam and fiber composite. In various embodiments, the foam and fiber composite can be incorporated into an absorbent article as a component of an absorbent system located between a topsheet layer and a backsheet layer of the absorbent article.

A method for hydroforming a spun bonded nonwoven web includes applying a plurality of pressurized liquid jets onto an original unexpanded spun bonded nonwoven web having an original loft while the web passes over a forming structure. A plurality of spun bonded fibers in the original unexpanded spun bonded nonwoven web are reoriented from a closely packed substantially horizontal orientation to a more loosely packed orientation with greater vertical spacing between the fibers to produce a hydroformed expanded spun bonded nonwoven web having a loft of at least about 1.3 times greater than the original loft of the original unexpanded spun bonded nonwoven web, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web. The hydroformed expanded spun bonded nonwoven web has a surface with a plurality of protuberances in a pattern corresponding to the pattern of apertures in the forming structure.

A method for hydroforming a composite precursor material includes forming a composite precursor material comprising an original spun bonded nonwoven web and a polymer film layer. The method also includes applying a plurality of pressurized liquid jets onto an outer surface of the original spun bonded nonwoven web while the composite precursor material passes over a forming structure to push and reorient a plurality of spun bonded fibers from a closely packed substantially horizontal orientation to a more loosely packed orientation with greater vertical spacing between the fibers to produce a hydroformed composite material comprising an expanded spun bonded nonwoven layer having a loft of at least about 1.3 times greater than the original loft of the original spun bonded nonwoven web, and an air permeability of at least about 1.2 times greater than an original air permeability of the original unexpanded spun bonded nonwoven web.
