<p>A fiber, a filament, yarn and/or a flat article and/or nonwoven material containing these, which has on its surface a microstructure consisting of dotted, linear and/or areal depressions and/or elevations, which have a depth or height, respectively, up to ca. 10 micrometers and extend across ca. 10% to 100% of the surface of the fiber and/or the filament. A process for the manufacture of the fiber, the filament, yarn, flat article and/or nonwoven material provides that the fiber, the filament, yarn, flat article and/or nonwoven material is irradiated with a laser, and that as a result its surface is fused, melted on and/or removed in a dotted, linear and/or areal fashion.</p> |
