Abstract

Es ist ein Verfahren zum Herstellen einer Borste insbesondere für eine Zahnbürste beschrieben, bei dem ein Filamentfaden nach dem Extrudieren abgekühlt, wieder erwärmt und verstreckt sowie gegebenenfalls unter Spannung erwärmt wird. Erfindungsgemäss wird der Filamentfaden spannungslos oder zumindest nahezu spannungslos erwärmt. Dies stellt ein zusätzliches Annealing dar, mit dem insbesondere die Verschleisseigenschaften der Borste wesentlich verbessert werden.
