Composite with an absorbent layer
The present invention relates to a multilayer product 1 having at least one first layer 2 , an absorbent intermediate layer 3 and a second layer 4 , whereby at least the first layer 2 contains at least one first material 5 and one second material 6 . The first layer 2 and/or the second layer 4 is at least partially liquid permeable. The first material 5 has a higher melting point than the second material 6 , with the second material 6 creating a bond to the second layer 4.
1. A composite multilayer absorbent product comprising: a liquid permeable spunbond nonwoven first layer, a second layer, and an adsorbent intermediate layer located between said first and second layers, said absorbent intermediate layer including a blend of absorbent fibers and a powder, said blend being located in selected areas across the multilayer absorbent product and defining zones between said selected areas that are free of said blend, at least the first layer including a first polymeric material and a second polymeric material, wherein the first polymeric material has a higher melting temperature than the second polymeric material, and wherein the second polymeric material of the first layer creates a bond with the second layer in said zones, and the powder of the intermediate layer is immobilized by the second polymeric material in said selected areas.
2. The multilayer product according to claim 1 , wherein the first layer contains first fibers comprising the first material and contains second fibers comprising the second material.
3. The multilayer product according to claim 1 , wherein the first layer contains first fibers comprising the first material and contains second fibers comprising the first material and the second material.
4. The multilayer product according to claim 1 , wherein the second material is in contact with the intermediate layer.
5. The multilayer product according to claim 1 , wherein the second material is chemically and/or physically bonded to the second layer and/or penetrates into the second layer.
6. The multilayer product according to claim 1 , wherein the second material seals the intermediate layer at the sides in interaction with the second layer.
7. The multilayer product according to claim 1 , wherein only the second material of the first layer is in contact with the second layer.
8. The multilayer product according to claim 1 , wherein the second layer contains the second material of the first layer.
9. The multilayer product according to claim 1 , wherein the second material of the first layer is at least partially fused with the second layer.
10. The multilayer product according to claim 1 , wherein the first layer comprises a homopolymer as the first material and contains a polyethylene as the second material.
11. The multilayer product according to claim 1 , wherein the first layer comprises bicomponent fibers.
12. The multilayer product according to claim 1 , wherein a hygiene article contains the multilayer absorbent product to absorb a fluid.
13. The multilayer product according to claim 1 , wherein an article contains the multilayer absorbent product to influence the odor of its environment.
14. The multilayer product according to claim 11 , wherein the bicomponent fibers contain said first and second materials.
15. A composite multilayer absorbent product comprising a liquid permeable spunbond nonwoven first layer, a second layer, and an absorbent intermediate layer located between said first and second layers, said absorbent intermediate layer including a blend of absorbent fibers and a powder, said blend being located in selected areas across the multilayer absorbent product and defining zones between said selected areas that are free of said blend, at least the first layer including bicomponent fibers containing a first polymeric material and a second polymeric material, wherein the first polymeric material has a higher melting temperature than the second polymeric material, and wherein the second polymeric material of the bicomponent fibers of the first layer creates a bond with the second layer in said zones, and the powder of the intermediate layer is immobilized by the second polymeric material in said selected areas.
16. The multilayer product according to claim 15 , wherein the first polymeric material comprises polypropylene and the second polymeric material comprises polyethylene, and wherein the polymeric materials are in a side-by-side arrangement in the bicomponent fibers.
