ABSTRACT:
The invention provides novel, improved wear indicating brush filaments and novel, improved coextrusion process for their manufacture. Essentially, the filaments of the present invention are coextruded filaments which include a longitudinal surface providing a boundary about the cross-sectional area of the filament and the longitudinal surface and/or the cross-sectional area presents a two colored region adapted to provide a visual signal indicative of wear in response to filament use. The filaments can be natural or synthetic materials. In filaments of the present invention, the colored region provides an initial color or color intensity viewable to the user. As wear is produced by continuing use of the filaments, the intensity of the colored region changes to a point which signals the user that the filament no longer provides the requisite performance characteristics for effectively performing its assigned function.
