Abstract	The use of biodegradable polymers is increasingly attracting interest over the last years, since they can reduce the environmental effects related to disposal of traditional plastics and, in general, the use of fossil, non-renewable resources. One of the most promising applications is represented by fibers production. However, the orientation and the crystallinity degrees can significantly affect the mechanical properties. Therefore, it is of interest to investigate on the optimum processing conditions, in order to improve the mechanical properties. In particular, while crystallinity can be slightly modified by the processing, orientation can be significantly improved. In this work, the effects of hot stretching on the mechanical and structural properties of fibers made from two different families of biodegradable blends were investigated. The orientation proved to significantly change the mechanical properties, and it was shown that factors such as the different relaxation times, the different crystallization temperatures and the cooling rate can give opposite effects in the three investigated polymer systems with significant consequences on the mechanical behaviour of the fibers. In particular, the behaviour during fiber production in hot stretching, and the orientation mechanisms were studied and explained on the basis of rheological and thermal properties of the polymers.
