N2 - Short-lived geotextiles find application in soil erosion protections and can improve seeding conditions on exposed surfaces. They usually are produced in the form of fibrous mats, which are fabricated from natural fibers or thermoplastic biopolyesters. In this work four different biopolyester were used for producing biodegradable fibers by a melt spinning process, which were then characterized by tensile testing. The fibers were exposed to artificial weathering in order to investigate the influence of moisture and UV-light radiation on the mechanical stability. The results were compared to non-stabilized polypropylene fibers, which are conventionally applied in synthetic geotextiles. Most biopolyester showed promising results regarding fracture strength even after 750 h of exposure. However the elongation at fracture was drastically reduced indicating embrittlement of the fibers.
