Abstract
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 continuous 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.
