摘要： Filaments are produced from polymers having an inherent viscosity of at least 0.7 measured in concentrated sulfuric acid and containing in the polymer chain at least 50 per cent of the repeating units :
by melting the polymer and heating the melt to a temperature of from about 20°C to about 80°C above the melting point of the polymer, passing the melt through a filter pack having a filtering area of at least about 8in (51.5 cm 2 ) and a total volume of at least about 1.2 in 3 (19.5 cm 3 ) per pound of polymer extruded per hour, and containing inert, irregularly shaped particles having a mesh size of about 25 to 140 to provide a pressure drop at least about 800 psig (57273 g/cm 2 ), extruding the melt through spinning openings of desired shape to form filaments. A preferred embodiment also includes the step of passing the filaments immediately upon extrusion through a heating zone maintained at a temperature of about 200 to 320°C and having a length of about 3 to 12 inches (7.6 to 30.5 cm). The process is capable of producing fibers and yarns having a dpf of about 2.8 to 100, a tenacity of about 1 to 4.5 grams per denier, an elongation at break of about 15 to 200 percent and modulus of about 20 to 80 grams per denier.
