Abstract

Provided are layered non-woven structures comprising a fibrous, water-permeable anchoring layer and a fibrous layer having fibers entangled about the anchoring layer, including patterned and non-patterned structures The structures provide high drapeability Also provided are personal care products such as sanitary pads and wipes comprising the present structures and methods of making the structures.

Claims (22)

1. A layered, composite material comprising a fibrous, fluid-permeable anchoring layer having tensile strength of at least about 5 N/5cm and a fibrous layer comprising fibers entangled about said anchoring layer, said composite material comprising a cross-section of entangled region and a cross-section of unentangled region, said entangled region and unentangled region being visibly distinct from one another.
2. The composite material of claim 1 having an LSV of greater than about 20 grams.
3. The composite material of claim 1 having an LSV of greater than about 50 grams.
4. The composite material of claim 1 having a drapeability of greater than about 8 gsm/g.
5. The composite material of claim 1 wherein said material has a drapeability of greater than about 16 gsm/g.
6. The composite material of claim 1 wherein said material has a density of less than about 0.15 g/cc.
7. The composite material of claim 1 wherein said material has a density of less than about 0.12 g/cc.
8. The composite material of claim 1 wherein said anchoring layer is selected from the group consisting of spun-bonded material, through air-bonded material, and combinations of two or more thereof.
9. The composite material of claim 8 wherein said anchoring layer comprises a spun-bonded material comprising one or more polyolefin fibers.
10. The composite material of claim 1 wherein at least a portion of the fibers of said fibrous layer having fibers entangled about said anchoring layer comprise cellulose fibers.
11. The composite material of claim 10 wherein said cellulose fibers comprise wood pulp.
12. The composite material of claim 10 wherein said wood pulp comprises mercerized pulp.
13. A personal care product comprising a material of claim 1.
14. The personal care product of claim 13 wherein said product comprises a sanitary pad or wipe.
15. The personal care product of claim 13 wherein said product is a sanitary pad comprising a topsheet comprising the material of claim 1.
16. The personal care product of claim 13 wherein said anchoring layer comprises a body-faceable surface of said sanitary pad.
17. A method of forming a layered, composite material comprising urging a stream of fluid into contact with a layered structure comprising a layer of unbonded fibers and a fluid-permeable, anchoring layer having a tensile strength of at least about 5 N/5cm, wherein said anchoring layer is positioned to a least partially shield said layer of unbonded fibers from said stream of fluid, to produce a composite material comprising a cross-section of entangled region and a cross-section of unentangled region, said entangled region and unentangled region being visibly distinct from one another.
18. The method of claim 17 further comprising positioning a translatable mask between such stream of fluid and such layered structure to at least partially shield said layered structure from said stream of fluid.
19. The method of claim 17 wherein said stream entangles at least a portion of the fibers of said layer of unbonded fibers about said anchoring layer.
20. The method of claim 17 wherein said anchoring layer comprises a spun-bonded material comprising one or more polyolefin fibers.
21. The method of claim 17 wherein at least a portion of the unbonded fibers comprise cellulose fibers.
22. The method of claim 21 wherein said cellulose fibers comprise mercerized pulp.
