Abstract
Abstract Bristle articles comprise a bristle carrier and bristles mechanically or thermally fixed thereto and formed from plastic monofilaments, optionally combined into bundles. For increasing the cleaning, distributing or application function of such bristle articles, over at least part of their length the monofilaments are flocked with short plastic fibres. Such bristle articles can be produced in that the surface of the monofilaments is provided with an adhesive or the surface thereof is heated to the soft plastic state and subsequently the fibres are applied to the monofilament in an electrostatic field. Instead of this, it is also possible to subsequently apply the fibres to the bristles connected to the bristle carrier, e.g. by means of an adhesive.
