Abstract

The present invention relates to a process for producing bristle materials suitable for inserting into toothbrushes and based on synthetic fibres which have been roughened on their surface by mechanical action, in particular by means of a blast apparatus, the roughening being accomplished on the endless fibre strand after stretching. Using these bristle materials, toothbrushes with an improved plaque-removing action can be produced.
