Claims (18)
- Monofile in Form von Bikomponentenfäden des Kernmanteltyps umfassend einen Kern, der ein flüssig-kristallines Polymer enthält, und einen im wesentlichen homogenen Mantel, der einen Polyester enthält.
- Monofile nach Anspruch 1, dadurch gekennzeichnet, daß der Mantel Polyethylenterephthalat, Polybutylenterephthalat, Polyethylen-2,6-naphthalat oder Poly-(1,4-bis(hydroxy-methyl)-cyclohexanterephthalat enthält.
- Monofile nach Anspruch 1, dadurch gekennzeichnet, daß der Mantel Polycarbonat enthält.
- Monofile nach Anspruch 1, dadurch gekennzeichnet, daß der Mantel einen elastomeren Polyester enthält.
- Monofile nach Anspruch 4, dadurch gekennzeichnet, daß der Mantel als elastomeren Polyester Polytetrahydrofuranbutylenterephthalat enthält.
- Monofile nach mindestens einem der Ansprüche 1 bis 5, dadurch gekennzeichnet, daß der Mantel aus einer Mischung von 1 bis 5 Gew.-% Polycarbonat und dem Rest zu 100 aus einem oder mehreren Polyestern besteht, die kein Polycarbonat sind.
- Monofile nach mindestens einem der Ansprüche 1 bis 6, dadurch gekennzeichnet, daß der Mantel 1 bis 15 Gew.-% des flüssig-kristallinen Polymers enthält, aus dem der Kern aufgebaut ist.
- Monofile nach mindestens einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß der Mantel aus einer Mischung besteht, welche 1 bis 20 Gew.-% eines fluorhaltigen Polyolefins und den Rest zu 100 Gew.-% Polyester enthält.
- Monofile nach mindestens einem der Ansprüche 1 bis 8, dadurch gekennzeichnet, daß die Querschnittsfläche des Kerns 40 bis 90 % und die Querschnittsfläche des Mantels 10 bis 60 % der gesamten Querschnittsfläche des Monofils ausmacht.
- Monofile nach mindestens einem der Ansprüche 1 bis 9, dadurch gekennzeichnet, daß das Monofil einen runden, ovalen, rechteckigen oder n-eckigen Querschnitt mit n ≥ 3 aufweist.
- Monofile nach mindestens einem der Ansprüche 1 bis 10, dadurch gekennzeichnet, daß der Kern zentriert angebracht ist.
- Monofile nach mindestens einem der Ansprüche 1 bis 11, dadurch gekennzeichnet, daß der Kern asymmetrisch angeordnet ist.
- Monofile nach mindestens einem der Ansprüche 1 bis 12, dadurch gekennzeichnet, daß der Kern und/oder der Mantel 0,1 bis 3 Gew.-% Mono- und/oder Polycarbodiimid als Verschlußmittel enthält.
- Monofile nach mindestens einem der Ansprüche 1 bis 13, dadurch gekennzeichnet, daß der Durchmesser der Monofile mindestens 0,08 mm, vorzugsweise mindestens 0,1 mm, beträgt.
- Verfahren zur Herstellung von Monofilen in Form von Bikomponentenfäden des Kernmanteltyps, dadurch gekennzeichnet, daß man ein Kernmaterial, welches ein flüssig-kristallines Polymer enthält, und ein im wesentlichen homogenes Mantelmaterial, welches einen Polyester enthält, als Schmelze durch ein Werkzeug zur Herstellung von Kernmantelfäden extrudiert, die austretenden Monofile unterhalb der Spinndüse mittels eines temperierten Gasstroms oder einer Flüssigkeit auf eine Temperatur abkühlt, welche mindestens 0 bis 30°C unterhalb der Glasumwandlungstemperatur des Mantelmaterials liegt, wobei man Austrittsgeschwindigkeit (Spritzgeschwindigkeit), ausgedrückt in Volumen pro Fläche und Zeit, und Abzugsgeschwindigkeit so aufeinander abstimmt, daß ein Spinnverzug von 1:5 bis 1:30, vorzugsweise 1:8 bis 1:15, erhalten wird und die Monofile gegebenenfalls aufspult und sowie gegebenenfalls tempert.
- Verwendung der Monofile nach mindestens einem der Ansprüche 1 bis 14 oder hergestellt nach einem Verfahren gemäß Anspruch 15 zur Herstellung von Sieben oder Filtern.
- Verwendung der Monofile nach mindestens einem der Ansprüche 1 bis 14 oder hergestellt nach einem Verfahren gemäß Anspruch 15 zur Herstellung von Papiermaschinenbespannungen, insbesondere für die Forming-, die Preß- und die Trockenpartie.
- Verwendung der Monofile nach mindestens einem der Ansprüche 1 bis 14 oder hergestellt nach einem Verfahren gemäß Anspruch 15 zur Verstärkung von Elastomeren.
