    摘要： A nonwoven fibrous web and a method of making thereof. The nonwoven fibrous web includes greater than 0% but no greater than 30 wt % of a plurality of melt-blown fibers comprised of a crystalline (co)polymer; and at least 70 wt % of a plurality of randomly-oriented staple fibers, the plurality of randomly-oriented staple fibers including: at least 60 wt % of oxidized polyacrylonitrile fibers; and from 0 to 40 wt % of reinforcing fibers having an outer surface comprised of a (co)polymer with a melting temperature of from 100° C. to 350° C.; wherein the plurality of melt-blown fibers and the plurality of randomly-oriented staple fibers are bonded together to form a cohesive non-woven fibrous web.

    摘要： A process for continuously bonding staple fibers into an essentially non-twisted yarn comprising the steps of introducing into a fiber arrangement composed of staple fibers an excess of a liquid containing an adhesive in distributed form, squeezing excess liquid out of the fiber arrangement, compacting the fiber arrangement by applying pressure to form a moist slubbing, and for setting the adhesive and transforming the slubbing into a bonded yarn bringing into contact as by feeding the slubbing into a condensing vapor atmosphere.The yarn produced according to the aforementioned process, compared to a yarn set in dry air with the same quantity of adhesive, possesses a higher breaking length and rupture or break elongation and a smoother surface.
