PROBLEM TO BE SOLVED: To obtain plush woven or knitted stuff, soft, bulky, and highly repulsive, by jetting high-pressure columnar fluid streams onto woven or knitted stuff of solvent-spun cellulosic fibers, and rubbing the stuff. SOLUTION: This plush woven or knitted stuff covered with fibrils is obtained by jetting high-pressure (20 to 150 kg/cm2) columnar fluid streams onto woven or knitted stuff of solvent-spun cellulosic fibers with an amine oxide-based solvent (e.g. N-methylmorpholine-N-oxide), and then rubbing the stuff, preferably using a machine (e.g. the one rubbing the stuff with liquid streams), to fibrillate the cellulosic fibers.
