Abstract
Method for quickly forming and modifying the structure of a film or filamentary polymeric material, characterized in that it comprises the extrusion of a molten polymer material capable of being hot-spun and presenting a crystallization, by passing through a hole or row to the formation of a film or of a fused filamentary material, the circulation of the film or of the molten filamentary material formed, in the longitudinal direction, by a solidification zone having a gaseous atmosphere at a temperature lower than the glass transition temperature of the material, so that the film or the fused filamentary material is transformed to the solid state, the circulation of the film or material formed, in the longitudinal direction, by a treatment zone having a gaseous atmosphere at a temperature above the temperature of vitreous transition of the material or lower than the melting temperature of the material, with a residence time of approximately 0.0001 to 0.8 seconds, so that a remarkable crystallization of the previously solidified film or filamentous material appears, and the removal of the resulting film or filamentary material from the area of treatment, at a speed of 1,000 to 6,000 m/minute, under a tension of approximately 0.1 to 1.0 g/denier, the treatment of the film or of the filamentous polymer material being carried out after extrusion, under a constant tension, in the absence of insulation against stresses along the film or filamentary material between the hole and the collection point from the treatment zone.
