Claims
- 1. A method for increasing the wet strength of a tissue material having cellulose fibres and wet strength agent, the method comprises curing the tissue material by subjecting the tissue material to a method selected from the group of corona treatment, plasma treatment, electronic beam treatment, or treatment with UV light.
- 2. A method according to claim 1, wherein, by means of the method, the wet strength of the tissue material, expressed as wet tensile strength MD, is increased more than about 15% in comparison with the normal wet strength-increasing effect.
- 3. A method according to claim 1, wherein, by means of the method, the wet strength of the tissue material, expressed as wet tensile strength MD×CD, is increased more than about 9% in comparison with the normal wet strength-increasing effect.
- 4. A method according to claim 1, wherein, by means of the method, the wet strength of the tissue material, expressed as relative wet strength, is increased more than about 7% in comparison with the normal wet strength-increasing effect.
- 5. A method according to claim 1, wherein the method is performed during or immediately after drying the tissue material in a drying device of a paper machine.
- 6. A method according to claim 1, wherein the method is performed during or immediately after creping the tissue material.
- 7. A method according to claim 1, wherein the method is performed in a separate post-treatment line.
- 8. A method according to claim 1, wherein the method is performed in a separate converting line for articles of said tissue material and with a converted article of the tissue material.
- 9. A tissue material comprising cellulose fibres and wet strength agent, said tissue material having been subjected to the method according to claim 1.
- 10. A tissue material according to claim 9, the tissue material having a wet tensile index MD×CD which is higher than about 2.5 Nm/g.
- 11. A tissue material according to claim 9, wherein the tissue material comprises 0.5-2.0 weight-% (dry) PAE-resin as a wet strength agent.
- 12. A method according to claim 1, wherein the method is performed in a separate converting line for articles of said tissue material.
- 13. A method according to claim 1, wherein the method is performed with a converted article of the tissue material.
