2101050 9213129 PCTABS00014 A process and apparatus for treating fabric articles containing cellulosic material to provide control shrinkage and durable-press properties for the fabric includes a system for exposing the fabric to an aerosol mist that uniformly supplies a liquid cellulosic cross linking agent and moisture to the fabric. Optionally, a liquid catalyst can be incorporated in the aerosol mist, whereby each droplet of the aerosol mist contains liquid cellulosic cross linking agent, moisture and catalyst promoting cross linking agent. Exposure of the fabric to the aerosol mist containing moisture, cross linking agent and catalyst, the fabric is cross linked at an elevated temperature and subsequently cleaned of cross linking chemicals. The fabric can also be treated using an aerosol mist containing other liquid chemical agents. Equipment for carrying out the process essentially includes a chamber having aerosol mist generating nozzles in communication with the interior of the chamber and appropriate supplies for compressed air and liquid chemicals in communication with the nozzles. Appropriate ventilating and heating systems are associated with the chamber.
