Composites material with improved high viscosity fluid intake
View Patent ↗A liner system suitable for use in personal care absorbent products having a composite material including a substructure applied to a first layer. The first layer and the substructure define a plurality of voids for accommodating passage of fluids through the composite material. In one embodiment, high viscosity fluids including the particles contained therein pass through a plurality of apertures in the first layer. The voids defined by the first layer and the substructure entrap the particles to accommodate passage of fluids through the composite material.
1. A composite material, comprising:
a first layer forming a plurality of apertures; and
a substructure bonded to the first layer at a plurality of bonding locations to form a plurality of compartments, the first layer apertures forming fluid communication between the first layer and the substructure and the compartments entrapping particles contained within a fluid which passes.
2. The composite material of claim 1 , wherein the compartments have a triangular cross section.
3. The composite material of claim 1 , wherein each compartment has a height of about 0.1 cm to about 2.0 cm.
4. The composite material of claim 1 , wherein each compartment has a width of about 0.1 cm to about 2.0 cm.
5. The composite material of claim 1 , wherein the first layer comprises a film.
6. The composite material of claim 1 , wherein the first layer comprises a film and fiber combination.
7. The composite material of claim 1 , wherein the first layer comprises a spunbond material.
8. The composite material of claim 1 , wherein the first layer comprises a hydrophobic material.
9. The composite material of claim 1 , wherein the first layer includes a plurality of apertures having a diameter of about 100 microns to about 10,000 microns.
10. The composite material of claim 1 , wherein the first layer has a basis weight of about 0.3 osy to about 2.5 osy.
11. The composite material claim 1 , wherein the first layer has a basis weight of about 0.44 osy to about 1.0 osy.
12. The composite material of claim 1 , wherein the substructure comprises a three-dimensional nonwoven material.
13. The composite material of claim 1 , wherein the substructure comprises a spunbond material.
14. The composite material of claim 1 , wherein the substructure comprises a melt spun material.
15. The composite material of claim 1 , wherein the substructure is pleated, corrugated, thermoformed or embossed.
16. The composite material of claim 1 , wherein the substructure is bonded to the first layer by one of point bonding, adhesive bonding and spiral bonding.
17. A personal care absorbent product comprising the composite material of claim 1 .
18. The composite material of claim 1 , wherein the material is one of a spacer layer, a fastener, a filter medium, an air filter, a liquid filter, a facemask, and a wipe.
19. A combination comprising:
a liquid permeable composite material of claim 1 ;
an outer cover bonded to the liner; and
an absorbent core positioned between the outer cover and the liner.
20. The composite material of claim 1 , wherein the substructure is pleated.
21. A feminine hygiene product comprising the composite material of claim 1 .
22. A wound care product comprising the composite material of claim 1 .
23. A diaper comprising the composite material of claim 1 .
24. Training pants comprising the composite material of claim 1 .
25. Swim wear comprising the composite material of claim 1 .
26. Absorbent underpants comprising the composite material of claim 1 .
27. An adult incontinence article comprising the composite material of claim 1 .
