DEFINITION

Classification: 8/115.51

CHEMICAL MODIFICATION OF TEXTILES OR FIBERS OR PRODUCTS THEREOF:

Processes for treating textiles, fibers, fabrics fibrous of filamentary materials, cloth, gauze, etc., (herein referred to as "materials") to affect a chemical modification thereof.

(1) Note. Subclasses 115.51+ includes processes or products thereof modifying the chemical or physicochemical properties of "materials", i.e., the "materials" are acted upon by a chemical or other agent as distinguished from the mere coating, impregnating, precipitation of a substance within the "materials" structure which are classified in Class 427. Excluded from here also are those processes or products thereof which are concerned with the coating, impregnation of precipitation by an in situ chemical reaction which does not chemically involve the substrate "material". Also found here are those chemical effects on a component normally associated with a "material", for example, sericin of silk.

(2) Note. The chemical modification of paper is classified here because of its similarity to other cellulosic "materials".

(3) Note. In the case of coating or impregnating processes

or products thereof, where doubt exists as to whether or not a chemical modification has occurred, the process or product thereof is classified in Class 427 and generally cross-referenced to this class, subclass 115.51.

(4) Note. The chemical modification of a substance other than a textile or fiber with subsequent processing to produce a textile, fiber, web, etc., is not classified here. For example, the chemical modification of polyvinyl chloride with subsequent fiber formation with no claimed structure of characteristics is in Class 525.

(5) Note. The heat treating of "materials", e.g., to produce carbon fiber precursors, is properly classified here despite the lack of a chemical agent since the chemical nature of composition of the "material" was altered.

(6) Note. Patents claiming a product derived from chemically modified "material" are classified on the basis of the process for chemically modifying the "material". SEE OR SEARCH THIS CLASS, SUBCLASS:

114+, for processes including chemical modification of the "material" which produces and ornamental effect.

162, Paper Making and Fiber Liberation,

157.1+, which utilizes fibers (including those chemically modified) in paper making processes.

252, Compositions,

8.61+, for durable finishes for textile materials, including antistatic and textile softening compositions, and subclasses 8.81+ for textile processing aid compositions, such as lubricants.

260, Chemistry of Carbon Compounds, and its daughter classes appropriate subclasses for the preparation of carbon compounds employing fibers or other "materials" as a reactant whether or not its composition is known, in which the fiber or other material reactant and/or product has no claimed structure of characteristics.

423, Chemistry of Inorganic Compounds,

447.1, in which the chemical modification results in a "material" of substantially pure carbon.

427, Coating Processes, for coating processes which do not modify the chemical or physicochemical properties of textiles and fibers.

428, Stock Material of Miscellaneous Articles, for a "material" obtained by a Class 8 process and whose structure or characteristics meet the required definition for that class.

510, Cleaning Compositions for Solid Surfaces, Auxiliary Compositions Therefor, or Processes of Preparing the Compositions,

515+, for nondurable antistatic compositions used in the course of a laundering operation or in a finishing step, such as rinsing or drying, accompanying laundering.
