<p>Fibre, filament, yarn and/or surface formations containing any of these and/or debris material having on its surface a microstructure which contains point-like, linear and/or flat depressions and/or protrusions, extending to a depth or height of about 10 microns over about 10% to about 100% of the surface of the fibre and/or filament. A process for the production of the fibre, filament, yarn, surface formation and/or debris material consists of irradiating with a laser the fibre, filament, yarn, surface formations and/or debris material and thereby melting on and/or removing the surface thereof in a point like, linear and/or flat manner.</p> |
