The brush (1) comprises a multiplicity of bristles (2) mounted on a core (3) and oriented transversely relative to this core. At least some of the ends (5) of the bristles (2) of the brush, furthest from the core (3), are shredded and have small hooks (6). These shredded ends (5) may be obtained by rotary grinding using a grinding wheel (8).
