PATENT No 23.797 A/75 - The present invention refers to a process to produce fibrous structures having an high degreee of monoaxial orientation, by means of controlled extrusion of solutions, emulsions, suspensions of fibrogenous thermoplastic polymers. In particular, one fixes the optimum conditions of the extrusor design in order to obtain a birefringence higher than $0.1\hskip 2pt 10^{-4}$.
