PCT No. PCT/US80/01387 Sec. 371 Date Oct. 17, 1980 Sec. 102(e) Date Oct. 17, 1980 PCT Filed Oct. 17, 1980 PCT Pub. No. WO82/01567 PCT Pub. Date May 13, 1982.To impregnate loose cotton staple and like fibers with chemicals, a mass of such fibers is fed into and through a series of compartments in a baffled housing assembly and is there acted upon by a series of cooperating rotating paddle assemblies while in contact with a chemical containing aqueous liquor at room temperature and atmospheric pressure. The paddle assembly initially produces, with the liquid, turbulent columns of bubbles within each of the compartments, with the result that the cotton fibers are located in the thin walls between the bubbles. The paddles forming the paddle assemblies comprise thin rigid smooth flat sheets of expanded metal with a uniform array of sharp-edged holes therein and are arranged to pick up the frothy mass of cotton and water from the columns and then position the fibers in thin films of chemical-bearing liquor on the flat rapidly moving paddle surfaces and dewater the resulting extremely thin films, and knead the fibers individually by impacting and/or massaging actions and thereby impregnate the lumen of each of such fibers with such liquor and thereby permanently locate such chemicals within such fibers.
