A multi-lobed fiber includes a fiber and additives. The fiber has a cross-section including a core portion and a plurality of lobes. Each of the lobes includes an inner end connected to the core portion, and an outer end protruding from the core portion. The additives are disposed in the fiber. Each of the additives includes an outer point distal to the core portion, and the outer point of the additive is closer to the core portion than the outer end of the lobe.

The present invention is directed to articles comprising nanofibers. The nanofibers, having a diameter of less than 1 micron, may comprise a significant number of the fibers in one layer of the web contained by the article. Preferably, the nanofibers are produced in a melt film fibrillation process. The articles include diapers, training pants, adult incontinence pads, catamenials products such as feminine care pads and pantiliners, tampons, personal cleansing articles, personal care articles, and personal care wipes including baby wipes, facial wipes, and feminine wipes.

A fibrous structure including filaments wherein the filaments comprise one or more filament-forming materials and one or more active agents that are releasable from the filament when exposed to conditions of intended use, the fibrous structure further having at least three regions. Methods of treating fabrics with a fibrous structure are also provided herein.

Bags, such as L-sewn bags and multi-substrate bags, are formed at least in part from an open mesh material that includes filaments that intersect one another. At least some of the filaments are composite filaments having a carrier portion of a relatively high melting point and a bonding portion of a relatively low melting point, the bonding portion of each composite filament being thermally bonded to other filaments at points of intersection. The material may be a non-woven fabric that contains at least two layers of weft filaments that may be bordered on one or both sides by a layer of warp filaments. When compared to other open mesh materials, the open mesh material disclosed herein has a superior combination of some or all of high strength, light weight, high dimensional stability, and openness. Also disclosed herein are methods of making and using such bags.

A method for manufacturing a composite material includes forming a composite precursor material comprising a nonwoven layer comprising a plurality of fibers and a polymer film layer laminated to the nonwoven layer; forming a plurality of apertured extended cells in the polymer film layer, each of the apertured extended cells having a continuous sidewall extending away from the nonwoven layer that terminates in an aperture at a distal end; and, while forming the plurality of apertured extended cells, pushing, with a fluid, at least one of the fibers into at least one of the apertured extended cells so that a portion of the at least one of the fibers extends into the at least one of the apertured extended cells and through the aperture at the distal end.

An air through bonded nonwoven material is provided. The air-through bonded nonwoven material comprises a plurality of fibers, a first plurality of areas formed in the fibers and having a first fiber to fiber bond density, and a second plurality of areas formed in the fibers and having a second, different fiber-to-fiber bond density. The first plurality of areas do not overlap with the second plurality of areas. The first fiber to fiber bond density is greater than the second fiber to fiber bond density. The first plurality of areas are substantially free of a film. The second plurality of areas are substantially free of a film.
