✦ Synopsis

Excimer laser irradiation of polymers can be used to generate a modi-Ðcation of the surface morphology at the irradiated regions. The normally smooth surface of synthetic Ðbres can be modiÐed by this non-contacting technique to a regular, roll-like structure, which has a great e †ect on general properties of the Ðbre, e.g. adhesion of particles and coating, wetting properties and optical appearance.

Examples of practical, textile applications of this e †ect for modiÐcation of macroscopic properties of fabrics and non-wovens are discussed. In the laboratory, UV-laser irradiation was used to change the optical appearance of fabrics and to improve dust Ðltration properties of non-wovens. The adhesion of pigment dyes and particles on poly(ethylene terephthalate) and polyamide Ðbres could be greatly improved. Improvement of laser treated high performance Ðbres adhesion towards rubber and epoxy resin has been demonstrated. Some other applications of UV-laser treatment of polymeric material are brieÑy discussed.
