ABSTRACT:
A process and apparatus are disclosed for removing ammonia from fabric which has been previously treated with liquid ammonia, by subjecting the fabric to a solution of water saturated with ammonia maintained at a temperature level high enough to vaporize ammonia in the fabric without requiring commercially uneconomical input of heat energy. Subsequent steps remove the remainder of the ammonia and water trapped in the fabric, the system providing essentially complete recovery of all ammonia at substantially reduced heat energy expenditure.
