Non-woven structures and methods of making the same

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. Also provided are personal care

1 . A layered, composite material comprising a fibrous, fluid-permeable anchoring layer having tensile strength of at least about 5 N/5 cm 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/5 cm, 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.
