| 权利要求 | 2. A woven or knitted fabric as claimed in claim 1, in which the crimp yarn consists of polyamide fibers. 3. A woven or knitted fabric as claimed in claim 2, characterized in that as cation-active antimicrobial compound alkylaryl ammonium chlorides are used, especially ''''Eulan-Asept'''' of Bayer, Leverkusen. 4. A woven or knitted fabric as claimed in claim 1, wherein the crimp yarn consists of endless threads having 20 to 200 elementary filaments or fibrils of very high torsion crimp. 5. A woven or knitted fabric as claimEd in claim 4, wherein said elementary filaments have a titer of 3 denier or less. 6. A woven or knitted fabric as claimed in claim 1, characterized in that it is of high elasticity. 7. A woven or knitted fabric as claimed in claim 1, characterized in that it includes a plurality of layers which consist of crimp yarn and between which woven or unwoven textile interlayers of natural or synthetic or regenerated fibers are disposed, which are treated with cation-active antimicrobial compounds. 8. A woven or knitted fabric as claimed in claim 1, characterized in that as cation-active antimicrobial compound benzalkyl ammonium derivates are used. 9. A woven or knitted fabric as claimed in claim 1, characterized in that as cation-active antimicrobial compound phenolic polyoxymethylene derivates are used. 10. A woven or knitted fabric as claimed in claim 1, characterized in that as cation-active antimicrobial compound alkylaryl ammonium chlorides are used, especially ''''Eulan-Asept'''' of Bayer, Leverkusen. 11. A woven or knitted fabric as claimed in claim 1, characterized in that it is used as surgical dressing. 12. A woven or knitted fabric as claimed in claim 1, characterized in that it is used as surgical face mask. 13. A surgical dressing comprising one or more layers of woven or knitted fabric which fabric is made from crimp yarn and treated with cation-active antimicrobial compounds. 14. A surgical face mask comprising one or more layers of woven or knitted fabric which fabric is made from crimp yarn and treated with cation-active antimicrobial compounds. 15. An antimicrobial woven or knitted fabric comprising crimp yarn having molecules with anion groups, the fabric being treated with cation-active antimicrobial compounds such that the antimicrobial compounds are combined with the anion groups of the crimp yarn. 16. A woven or knitted fabric as claimed in claim 15, in which the crimp yarn consists of polyamide fibers. 17. A woven or knitted fabric as claimed in claim 16, wherein the crimp yarn consists of endless threads having 20 to 200 elementary filaments or fibrils of very high torsion crimp. 18. A woven or knitted fabric as claimed in claim 17, wherein said elementary filaments have a titer of 3 denier or less. 19. A woven or knitted fabric as claimed in claim 15, characterized in that as cation-active antimicrobial compound alkylaryl ammonium chlorides are used, especially ''''Eulan-Asept'''' of Bayer, Leverkusen. |
