Patentanspruch:Claim: Verfahren zur Herstellung von Mehrkomponentenfasern aus thermoplastischen Kunststoffes, wobei eine Grundkomponente in Form einer Kunststoffolie zusammen mit einer zweiten, ein anderes Schrumpfvermögen aufweisenden Komponente in Form einer Fadenschar in stoffschlüssigem Verbund extrudiert und die mit der Fadenschar versehene Kunststoffolie — ggf. nach Verstreckung — in Fasern zerlegt wird und letztere durch Schrumpfung gekräuselt werden, wobei die Fadenschar in bezug auf die Extrusionsrichtung der Kunststoffolie wellen- oder kreuzförmig extrudiert wird, nach Patent 2223780, dadurch gekennzeichnet, daß mehrere Kunststoffolien extrudiert und zwischen diesen eine oder mehrere Fadenscharen angeordnet werden.Process for the production of multi-component fibers Made of thermoplastic plastic, with a basic component in the form of a plastic film together with a second component having a different shrinkage capacity in The form of a group of threads is extruded in a cohesive bond and the one provided with the group of threads Plastic film - if necessary after stretching - is broken down into fibers and the latter by shrinkage be crimped, the thread sheet waving with respect to the extrusion direction of the plastic film or is extruded in a cross shape, according to patent 2223780, characterized in that extruded several plastic films and arranged between these one or more sets of threads will. Das Hauptpatent hat ein Verfahren zur Herstellung von Bikomponentenfasern aus thermoplastischen Kunststoffen zum Gegenstand, wobei eine Grundkomponenti; in Form einer Kunststoffolie zusammen mit einer zweiten, ein anderes Schrumpfvermögen aufweisenden Komponente in Form einer Fadenschar in stoffschlüssigem Verbund extrudiert und die mit der Fadenschar versehene Kunststoffolie — ggf. nach Verstreckung — in Fasern zerlegt wird und letztere durch Schrumpfung gekräuselt werden, welches dadurch gekennzeichnet ist, daß die Fadenschar in bezug auf die Extrusionsrichtung der Kunststoffolie wellen-S oder kreuzförmig extrudiert wird. Durch das Verfahren nach dem Hauptpatent können Fasern extremer Fälligkeit und Bauschigkeit erzeugt werden.The main patent has a process for the production of bicomponent fibers from thermoplastic Plastics to the subject, with a basic componenti; in the form of a plastic film together with a second one that has a different shrinkage capacity Component extruded in the form of a thread sheet in a cohesive bond and with the Plastic film provided with a thread bundle - if necessary after stretching - is broken down into fibers and the latter be crimped by shrinkage, which is characterized in that the thread sheet in relation is extruded in the direction of extrusion of the plastic film in a wave-S or cross shape. Through the procedure According to the main patent, fibers of extreme maturity and bulk can be produced. Demgegenüber liegt der Erfindung die Aufgabe zugrunde, das Verfahren nach dem Hauptpatent soIn contrast, the invention is based on the object, the method according to the main patent so ίο weiter auszubilden, daß Mehrkomponentenfasern aus thermoplastischen Kunststoffen hergestellt werden können, deren Fälligkeit und Bauschigkeit entsprechend dem mehrkomponentigen Aufbau weiter gesteigert istίο continue to train that multi-component fibers Thermoplastics can be produced, their maturity and bulkiness accordingly the multi-component structure is further increased Zur Lösung der Aufgabe lehrt die Erfindung, daß mehrere Kunststoffolien extrudiert und zwischen diesen eine oder mehrere Fadenscharen angeordnet werden. — Der Ausdruck Mehrkomponentenfasern meint im Rahmen der Erfindung einen Aufbau von Fasern, die zumindest aus einem Faden und zwei angeschlossenen Kunststoffolien bestehen. In werkstoffmäßiger Hinsicht kann der Aufbau so getroffen werden, daß die Folien und die Fasern aus gleichem Kunststoff bestehen, ma.i kann jedoch auch mit unterschiedlichen Kunststoffen arbeiten.To solve the problem, the invention teaches that several plastic films are extruded and between them one or more sets of threads are arranged. - The term multicomponent fibers means im Within the scope of the invention a structure of fibers, which consists of at least one thread and two connected Plastic foils exist. In terms of materials, the structure can be made so that the foils and the fibers are made of the same plastic, ma.i however, it can also work with different plastics. Die erreichten Vorteile sind darin zu sehen, daß bei dem erfindungsgemäßen Verfahren ohne weiteres Mehrkomponentenfasern hergestellt werden können, deren Fälligkeit und Bauschigkeit nicht nur durch die Effekte bestimmt ist, die für die Bikomponentenfasern des Hauptpatentes wesentlich sind, sondern zusätzlich durch den mehrkomponentigen Aufbau.The advantages achieved are to be seen in the fact that in the process according to the invention without further ado Multicomponent fibers can be produced whose maturity and bulkiness are not only due to the Effects is intended for the bicomponent fibers of the main patent are essential, but also due to the multi-component structure.
