Abstract: A recyling process for liquid treatment of denim scrap comprising placing denim scrap on a support surface (50) to form a thickness of flat, layered denim scrap (7). To the top surface is applied a compression plat (56) to form the thickness of denim scrap into a compact cake (54). Then treatment liquid is passed through the interior of the compact cake (54) in a direction parallel to the surfaces of the scrap, the liquid passing between opposed surfaces of the denim pieces. The treatment liquid can be a solvent for oxidized indigo dye; an aqueous solution containing a desizing agent; an aquueous solution containing a reducing agent for indigo dye; a solution containing desizing and reducing agent; an aqueous solution containing a reducing agent for indigo dye; or a sequences of these liquids.
