Abstract

Es ist ein Verfahren und eine Vorrichtung zur Herstellung von Stapelfasern aus schmelzgesponnenen Hohlfasern beschrieben. Um die Herstellung mit möglichst geringem apparativen Aufwand betreiben zu können, werden die Hohlfasern in einem kontinuierlichen Faserfluß vom Schmelzspinnen bis zum Zerschneiden geführt, wobei die Hohlfasern beim Schmelzspinnen einer Polymerschmelze jeweils durch eine ringsegmentförmige Düsenöffnung mit einem Hülldurchmesser im Bereich von 0,2 mm bis 0,8 mm und einem Hohlanteil von max. 60 % vorzugsweise max. 40 % extrudiert werden.
