Abstract
Excimer laser irradiation of polymers can be used to generate a modification of the surface morphology at the irradiated regions. The normally smooth surface of synthetic fibers can be modified by this technique to a regular, roll-like structure, which is of great effect to general properties of the fiber, e.g. adhesion of particles and coating, wetting properties, and optical appearance. A systematic study of the properties of the laser-induced surface structure as a function of experimental conditions is reported for varying types of polymer including high- performance fibers like aramides. The experimental data support a synergetic understanding of the effect, where laser-induced temperature fields and intrinsic stress fields are understood as cooperative driving forces of the effect. Examples of practical, textile applications of this effect for modification of macroscopic properties of fabrics and nonwovens are discussed. In laboratory scale UV-laser irradiation was used to change the optical appearance of fabrics and to improve dust filtration properties. The adhesion of pigment dyes and particles on poly(ethylene terephthalate) fibers could be improved to a degree similar to natural fibers like cotton.
