Claims (8)
- Nichtgewebtes Vlies, das mindestens zum Teil aus Endlosfäden oder zusammengesetzten Fasern hergestellt wird, die aus mindestens zwei Komponenten aus thermoplastischen polymeren Materialien bestehen, dadurch gekennzeichnet, dass es mindestens teilweise aus einheitlichen Fäden oder Fasern besteht, die zu 5 % bis 50 % ihres Gewichts ein Polymer umfassen, das dazu bestimmt ist, das Bindemittel darzustellen, und in ihrem Querschnitt mindestens zwei unterschiedliche Polymerbereiche oder -zonen aufweisen, die das Bindemittel darstellen, und/oder mindestens zwei unterschiedliche Polymerbereiche oder -zonen aufweisen, die die strukturelle(n) Komponente(n) des resultierenden Vlieses darstellen, wobei dieses Vlies nach der Herstellung einer Behandlung durch Thermobindung unterzogen wird.
- Nichtgewebtes Vlies nach Anspruch 1, dadurch gekennzeichnet, dass die Fasern oder Fäden zu 10 % bis 30 % des Gewichts das bindende Polymer umfassen.
- Nichtgewebtes Vlies nach irgendeinem der Ansprüche 1 und 2, dadurch gekennzeichnet, dass das bindende Polymer mehrheitlich in den peripheren Zonen der zusammengesetzten Fäden und Fasern gelagert ist und im Bereich von mindestens zwei unterschiedlichen Zonen der äußeren Oberfläche dieser Fäden oder Fasern sichtbar ist.
- Nichtgewebtes Vlies nach irgendeinem der Ansprüche 1 bis 3, dadurch gekennzeichnet, dass der Anteil der äußeren Oberfläche der Fäden oder Fasern, der vom bindenden Polymer besetzt ist, höher ist als der Gewichtsanteil dieses Polymers in der Zusammensetzung der Fäden oder Fasern.
- Nichtgewebtes Vlies nach irgendeinem der Ansprüche 1 bis 4, dadurch gekennzeichnet, dass das bindende Polymer und das oder die Polymere, die die strukturellen Komponenten darstellen, inkompatibel sind.
- Nichtgewebtes Vlies nach irgendeinem der Ansprüche 1 bis 5, dadurch gekennzeichnet, dass die einheitlichen Faden oder Fasern nach der Extrusion eine multisegmentierte und zusammengesetzte Struktur aufweisen und einem Trennungsvorgang unterzogen werden, wodurch gespaltene Fadenkomponente entstehen, von denen jede im Querschnitt mindestens zwei unterschiedliche Zonen des bindenden Polymers und/oder mindestens zwei unterschiedliche Polymerbereiche oder -zonen vereint, die dazu bestimmt sind, die strukturelle Komponente(n) des resultierenden Vlieses zu bilden.
- Nichtgewebtes Vlies nach irgendeinem der Ansprüche 1 bis 6, dadurch gekennzeichnet, dass die Fäden oder Fasern im Querschnitt eine äußere zylindrische Struktur und eine innere Struktur aufweisen, die aus der Gruppe gewählt wird, die aus den Strukturen in Lamellenform, in Form von Orangenschnitzen mit oder ohne zentraler Öffnung, in Sattelitenform mit oder ohne Ausstülpungen und in ergänzenden Auszahnungen besteht.
- Nichtgewebtes Vlies nach irgendeinem der Ansprüche 1 bis 6, dadurch gekennzeichnet, dass die Fäden oder Fasern im Querschnitt eine äußere multilappige Struktur aufweisen und die das Bindemittel darstellende Polymerbereiche oder -zonen vorzugsweise im Bereich der Extremitäten der Lappen gelegen sind.
