1. An apparatus for treating fibers with an ozone-steam mixture, which comprises(a) a chamber having a substantially horizontal open end section, and a horizontal middle section elevated at least 15 cm above said end section, said middle section having a top wall which is sloped in both directions from a center line, the magnitude of slope being sufficient to convey condensed gases down the side walls of said middle section and said middle section having a length sufficient to provide a residence time within said middle section for fibers conveyed therein to be treated by the ozone-steam mixture prior to exiting said middle section;

  • (b) means for introducing ozone into the central longitudinal part of said horizontal middle section of said chamber; and

    separate means for introducing steam into the central longitudinal part of said horizontal middle section to create an ozone-steam mixture within said horizontal middle section, said means for introducing ozone and for introducing steam located within said horizontal middle section such that in conjunction with the elevation of said middle section said ozone-steam mixture is substantially confined therein; and

    (c) means for moving the fibers through said chamber.
