Abstract (en)
[origin: DE19756760A1] To produce doll's hair, a filament (10) of a thermoplastic plastics material is extruded by dry spinning. During extrusion, an agent is introduced to form radial projections (12) at the surface (11) of the filament (10). The projections (12) are distributed evenly over the filament surface, as gas bubbles. The agent, to develop the surface projections, is chemical or physical. The filament (10) is hollow, with a ring-shaped cross section.
