Method and apparatus for treating continuously moving staple length textile fibrous materials to uniformly apply a liquid treating composition, such as a dye or other chemical thereto, wherein loose staple fibers are temporarily formulated into a web for continous delivery by gravity down a conveying chute into the nip portion of a pair of applicator rollers containing a treating liquid on their surfaces, and wherein the fiber conveying chute and its discharge end are maintained at preferred angles of inclination and distances from the nip of the two applicator rollers to facilitate continuous delivery of the fibers uniformly through the nip portion of the applicator rollers to improve the application of liquid materials thereto. The fibers are thereafter continuously conveyed for heat treatment in loose random staple length form and under compression through a RF energy confined heating tube.
In a method of treating staple length fibers to dye or otherwise chemically treat the same while continuously transporting the fibers in a predetermined path of travel to a point of collection, and including the steps of continuously delivering a metered amount of the fibers in generally loose random form, condensing the loose fibers into a web to increase their cohesion to each other, passing the web into and through a pair of nip rollers of a dye or chemical liquid composition applicator to impregnate the fibers with the liquid composition and express excess liquid therefrom, breaking up the web into smaller discrete fiber masses, and heating the moving liquid-impregnated fibers in a confined zone with high frequency energy while the fibers are maintained under compression to react the dye or other chemical with the fibers before their collection;
An improved method for uniformly impregnating staple length textile fibers while continuously moving the fibers in a desired path of treatment to a point of collection comprising the steps of continuously conveying a metered amount of loose fibers along said path, temporarily condensing the fibers into a web form to increase their cohesive integrity, passing the web under influence of gravity downwardly over a smooth fixed support and through and unsupported zone surface immediate for introduction into the nip of a pair of nip rollers having horizontal rotational axes disposed in a common vertical plane and carrying a treating liquid on their surfaces to impregnate the fibers, initially accelerating the speed of the condensed web in its downward movement and thereafter decelerating the speed of the web during its movement over the lower portion of the fixed support surface to further condense the same and ensure its longitudinal continuity as it passes from the support surface into the treating liquid and the nip portion of the rollers, breaking up the liquid impregnated fiber web exiting the rollers, and further treating the moving impregnated fibers before their collection.
A method of uniformly impregnating textile staple length fibers which are continuously moving in a desired path of treatment to a point of collection, comprising the steps of
