DEFINITION

Classification: 8/137

Processes for cleaning and laundering textile fabrics and fibers, including a fluid or chemical treatment. Includes also combinations and after treatments incidental to such operations not elsewhere classifiable.

(1) Note. Because of the similarity to treatment of textile fibers and fabrics, methods for washing and cleaning of furs, skins and leather are included in subclasses 137+ and in subclasses 147+ when the treatment is merely manipulative in nature.

(2) Note. Included herein are processes wherein fabric conditioners, e.g., softeners, etc., have been added to the laundering fluids.
