Title Improved Regenerated Cellulose Recovery Process Using a Humid Gas to Remove Coating Solvent Abstract of the Disclosure In a regenerated cellulose recovery process wherein (1) coated, softened, regenerated cellulose is comminuted, (2) the softener is removed leaving coated regenerated cellu- loss having open internal pores, (3) the coating is removed from the regenerated cellulose by flushing with a coating solvent, and (4) the regenerated cellulose is dried of coat- ing solvent, the improvement wherein the regenerated cellu- lose is dried of coating solvent by contacting the regenerated cellulose having a solvent content of at least about 6% by weight at an elevated temperature with a gas stream containing an effective amount of water vapor to raise the regenerated cellulose water content to about 7 to 22% by weight and to reduce the coating solvent content of the regenerated cellulose. In a preferred embodiment, steam is selected as the gas stream and residual coating solvent is reduced to less than about 1% by weight. - 1 -
