FIELD: mechanical engineering. SUBSTANCE: bristle has core of relatively solid flexing elasticity plastic and at least one layer of plastic having rubber elasticity and profiled by extruding on core. This layer may be coated with other layer made in the form of film adapted for leveling said profile. Method involves simultaneously extruding core and rubber elasticity layer, with following extruding thereof on core, with film-like layer being applied after extrusion process. EFFECT: improved strength combined with soft surface, increased efficiency in cleaning and absorbing substances. 29 cl, 3 dwg
