    摘要: Polyaryiene sulfone fiber material, especially web, is obtained by oxidizing polyarylene sulfide fiber material with a peracid/acid mixture of an organic acid at 60 to 100° C. for 10 seconds to 45 minutes. Since this process provides a substantative degree of oxidation within a very short reaction time, one advantage of the process is that the rapidity of the oxidation renders continuous processes for oxidizing polyarylene sulfide fibers economical.
