    CPC classification number: D01F6/74

    Abstract: The present invention concerns a process for making a polyareneazole multifilament yarn comprising: a) extruding a solution comprising polyareneazole polymer and polyphosphoric acid through a plurality of orifices to produce filaments; b) forming a multifilament yarn from said filaments; c) hydrolyzing at least some of the polyphosphoric acid in the yarn by heating the yarn to a temperature above about 120° C. for up to about two minutes; d) washing at least some of the hydrolyzed polyphosphoric acid from the yarn; e) drying the washed yarn; f) optionally, heating the yarn above about 300° C., and g) collecting the yarn at a speed of at least about 50 meters per minute.

    Abstract: A process for preparing high modulus, high tenacity fibers of aromatic polyamide wherein a first constant tension within 40-95% of the fiber breaking load is applied to washed fibers at a temperature of less than 50.degree. C. for a duration of greater than 5 seconds, and drying the fibers at a second constant tension which is from 10-100% of the first constant tension and at a temperature of more than the temperature of the first constant tension and less than 350.degree. C. until the fibers have a moisture content of about 2 to 10%.

    Abstract: The present invention concerns processes for reducing water in never-dried fiber comprising copolymer derived from the copolymerization of para-phenylenediamine, 5(6)-amino-2-(p-aminophenyl)benzimidazole; and terephthaloyl dichloride, the process having the following steps in a continuous process, (a) a step of drying a never-dried fiber having at least 0.1% sulfur at less than 150° C. until the moisture content of the fiber is less than 60 weight percent; and (b) a step of further drying the fiber above 150° C. while the moisture content of the fiber is no more than 60 weight percent; and the fiber being further heated to at least 350° C. in either an additional continuous or separate step.
