procedure for the manufacture of synthetic boerstematerialer for positioning in tandboerster, fibres for positioning in tandboerster and tandboerster equipped with such fibres

摘要

The present invention relates to a method for producing on the basis of synthetic fibres bristles which are adapted to be stuck into toothbrushes and have been roughened on their surface by mechanical action, in particular by means of a blasting blower, the roughening being carried out on the continuous fibre strand after drawing. These bristles can be used to produce toothbrushes with improved plaque-removing action.
