CARDED STAPLE FIBER NONWOVENS
A disposable absorbent article is described. The disposable absorbent article has a topsheet, a backsheet, and an absorbent core disposed between the topsheet and the backsheet. A carded staple fiber nonwoven having a basis weight of between about 50 grams per square meter (gsm) and about 100 gsm, includes a blend of absorbing fibers, stiffening fibers and filler fibers. The carded staple fiber nonwoven has a pore volume radius mode of between about 60 m and about 120 m.
Method Of Manufacturing A Wet-Laid Nonwoven Fabric
A method of manufacturing a wet-laid nonwoven web includes the following steps: feeding a pulp suspension onto a forming screen for depositing a fibrous web thereon, wherein the pulp suspension has industrially produced, inorganic fibers or fibers of synthetically produced polymers and the pulp suspension is substantially free from binders, such as chemical binders, and hydraulic consolidation of the fibrous web to generate the nonwoven web through water jet needling of the fibrous web.

Manufactured cloth wipers
Creating a set of manufactured cloth wipers from a set of cut sheets made from a non-woven substrate that has wood-pulp fibers hydroentangled with polyester. Saturating the set of cut sheets to a mixture of a mildew inhibitor and fabric softener and water. Removing water from the cut sheets with a water extractor and then partially drying the cut sheets in a dryer. Optionally, compressing a set of semi-dry cut sheets into a tightly compressed block; and placing the compressed block into a shipping container that allows for additional drying of the compressed block of cut sheets.

Hydro-formed film with three-dimensional micro-apertures
A method of processing a polymeric web includes providing a forming screen configured for supporting and moving with the web in a machine direction. The forming screen has a plurality of elliptical screen openings, each having a major axis perpendicular to the machine direction and a minor axis parallel to the machine direction. The method includes continuously depositing the web onto the forming screen and passing the web and forming screen through a water stream having a pressure level sufficient to cause the web to be forced into the screen openings, thereby forming protrusions extending from the planar surface of the web. Each protrusion has an apex, an opening at the apex, and an elliptical cross-section parallel to the planar surface of the web. The elliptical cross-section has a protrusion axis ratio that may be selected so as to produce a desired protrusion axis ratio.
METHOD FOR STRENGTHENING A NONWOVEN FABRIC
The invention relates to a method for strengthening a nonwoven fabric by means of a water jet treatment. The method according to the invention is characterized in that the nonwoven fabric contains flat fibers in the form of collapsed hollow viscose fibers with a ratio of width B to thickness D of B:D10:1.

Extensible non-woven, method for producing an extensible non-woven and use of same
The invention relates to an extensible non-woven, in particular, cover sheet material for a multi-layer laminate comprising hydroentangled staple fibers, where the non-woven contains 5 to 25 wt % of binder fibers made of thermoplastic material, in particular 10-15 wt % of binder fibers, and is in addition to hydroentanglement thermally bonded. Furthermore, the invention relates to an elastic multi-layer laminate for use in an elastic component for personal hygiene products composed of elastic base material covered on one or both sides by cover material, where the cover material is formed from extensible non-woven fabric.
