Abstract
Method of production of filaments, oriented and stretched, from thermoplastic polymers, comprising the extrusion of a molten thermoplastic polymer material through a spinneret with outlet on a quencher bath, the removal of the bath from the resulting filaments and the stretching of the same to guide them, introducing and continuously withdrawing tempering liquid in said bath, characterized in that the rate of passage of the tempering liquid through the bath is regulated in order to maintain it at a temperature of at least 38.88º c, and because the filaments they are removed from the bath according to a stretching ratio comprised between that in which the resistance to rupture of the filaments stops increasing with the increase of the levels of stretching and 10% above it, which increases the production rhythm, interruptions in production decrease and quality is improved.
