The invention relates to drawn filaments based on linear, branched or cyclic aliphatic or partially aromatic polyamides, wherein the filaments have been drawn at a temperature between the glass transition temperature and the melting point and wherein the filaments are cooled to room temperature under full tensile load. Filamentos estirados a base de poliamidas lineales, ramificadas o cíclicas, alifáticas o semiaromáticas, donde los filamentos han sido estirados a una temperatura entre la temperatura de transición vítrea y el punto de fusión y donde los filamentos se enfrían a temperatura ambiente bajo una carga de tracción total.
