DEFINITION

Classification: 252/8.61

DURABLE FINISHES FOR TEXTILE MATERIALS, OR PROCESSES OF PREPARING (E.G., CREASE RESISTANT, MOISTURE ABSORBENT, ANTISTATIC, ETC., FINISHES):

(under the class definition) Compositions specialized or designed for forming a lasting, nonfugitive finish on a textile substrate, such as fabric, yarn, or fiber, or processes of preparing the compositions.

(1) Note. Formation of these durable finishes (e.g., permanent-press, etc.) usually requires an additional step, such as application of heat, in order to "set" the coating after application.

(2) Note. Processes involving the mere use of a claimed composition are included in this and indented subclasses. If no composition is claimed or significant process steps are involved in addition to such mere use, the patent is classifiable in other appropriate classes.

(3) Note. As used herein, the term "textile materials" includes fabrics (woven, knitted, etc.), yarn, filaments, and fibers.

(4) Note. Patents including claims to both a composition and a textile material treated with the composition are classified in the class providing for the treated material and cross-referenced to this or indented subclasses.

112, for carroting compositions and subclasses 125+ for mercerizing baths. 427, Coating Processes, appropriate subclasses for processes of producing durable finishes on textile materials.

428, Stock Material or Miscellaneous Articles, appropriate subclasses, particularly

224+, and 357+, for textile materials carrying durable finishes.

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.

516, Colloid Systems and Wetting Agents; Subcombinations Thereof; Processes of Making, Stabilizing, Breaking, or Inhibiting, appropriate subclasses for subject matter relating to: colloid systems (such as sols*, emulsions, dispersions, foams, aerosols, smokes, gels, or pastes) or wetting agents (such as leveling, penetrating, or spreading); subcombination compositions of colloid systems containing at least an agent specialized and designed for or peculiar to use in making or stabilizing colloid systems; compositions and subcombination compositions specialized and designed for or peculiar to use in breaking (resolving) or inhibiting colloid systems; processes of making the compositions or systems of the class; processes of breaking (resolving) or inhibiting colloid systems; in each instance, when generically claimed or when there is no hierarchically superior provision in the USPC for the specifically claimed art.
