Abstract

Claims (21)

1. A fiber material comprising:

a substrate of non-ionic, non-woven fibers, and

at least one additional component, which is an agent that comprises at least one group capable of forming a hydrogen bond,

wherein a combination of the substrate and the agent causes the fiber material to have an increased wet tensile strength of at least 5%, as measured in accordance with EN 29073-3:1992, as compared to an otherwise identical fiber material without the agent.

2. The fiber material according to claim 1 , wherein the combination of the substrate and the agent causes the fiber material to have an increased wet tensile strength of at least 10%, as measured in accordance with EN 29073-3:1992, as compared to an otherwise identical fiber material without the agent.

3. The fiber material according to claim 2 , wherein the non-ionic, non-woven fibers are crosslinked by the agent.

4. The fiber material according to claim 1 , wherein the combination of the substrate and the agent causes the fiber material to have an increased wet tensile strength of at least 15%, as measured in accordance with EN 29073-3:1992, as compared to an otherwise identical fiber material without the agent.

5. The fiber material according to claim 4 , wherein the non-ionic, non-woven fibers are crosslinked by the agent.

6. The fiber material according to claim 1 , wherein the fiber material has a wet tensile strength of at least 2.5 N/2 cm, as measured in accordance with EN 29073-3:1992.

7. The fiber material according to claim 1 , wherein the fiber material has a wet tensile strength of at least 3.0 N/2 cm, as measured in accordance with EN 29073-3:1992.

8. The fiber material according to claim 1 , wherein the fiber material has a wet tensile strength of at least 4.0 N/2 cm, as measured in accordance with EN 29073-3:1992.

9. The fiber material according to claim 1 , wherein the non-ionic, non-woven fibers comprises polyvinyl alcohol (PVA), a polysaccharide, and/or a polyurethane polymer with polyethylene glycol (PEG) and/or polypropylene glycol functionalities, and/or copolymers thereof.

10. The fiber material according to claim 1 , wherein the agent that comprises the at least one group capable of forming a hydrogen bond comprises at least one of the following groups: a hydroxyl group, a carboxyl group, an amino group, a sulfhydryl group, and/or hydrogen donor linkages comprising a glycolytic linkage, or a peptide bond.

11. The fiber material according to claim 1 , wherein an amount of agent in the fiber material, relative to the overall weight of the fiber material, is from 1% w/w to 40% w/w.

12. The fiber material according to claim 1 , further comprising at least one antimicrobial agent.

13. The fiber material according to claim 1 , further comprising at least one absorbing material.

14. The fiber material according to claim 1 , wherein the substrate of non-ionic, non-woven fibers is a web of non-ionic, non-woven fibers.

15. The fiber material according to claim 1 , wherein the substrate of non-ionic, non-woven fibers comprises cross-linked PVA.

16. The fiber material according to claim 1 , further comprising at least one superabsorbent material in the form of particles.

17. The fiber material according to claim 1 , wherein the amount of agent in the fiber material, relative to the overall weight of the fiber material, is from 15% w/w to 25% w/w.

18. The fiber material according to claim 1 , wherein the agent comprises at least two groups capable of forming a hydrogen bond.
