ABSTRACT:
Process and apparatus for increasing the coherency of a filamentary tow by passing a tow through a turbulent fluid zone exerting a braking and vortical action on the filaments, and withdrawing the tow. Apparatus for forming the turbulent zone comprises fluid streams directed into a funnel-shaped treating chamber so that a major portion of the spent fluid discharges in a direction opposite to the tow motion. Tow delivery apparatus for delivering the tow to the treatment preferably includes a jet device for opening and forwarding the tow.
