Brush and method for its fabrication

Abstract

A brush has a bristle section comprising a plurality of bristles, bristle bundles or pins and is fixed to a bristle carrier. To reduce the risk of dirt accumulation and mold and bacteria formation, in the vicinity of the bristle section the bristle carrier surface is at least zonally and preferably full-surface sealed. The seal can be formed by a coating or by a bristle carrier surface layer compacted or compressed by thermal energy.
