DEFINITION

Classification: 252/8.81

TEXTILE PROCESSING AID COMPOSITIONS, OR PROCESSES OF PREPARING (E.G., LUBRICANTS OR ANTISTATIC AGENTS FOR FIBER, YARN, FABRIC, ETC.):

(under the class definition) Compositions specialized and designed to facilitate the processing of textile materials, such as the conversion of fibers, filaments, yarns, or fabrics into the finished product (such as thread or yarn; knitted, woven, or nonwoven fabric; or garment, carpet, blanket, etc.) whereupon the finish may be removed by such means as washing or scouring.

(1) Note. Such finishes are applied to staple fiber or continuous-filament yarns in order to reduce the tendency toward breakage of the individual fibers or filaments making up the yarn when subjected to mechanical processing, such as spinning, twisting, winding, texturizing by crimping or false twisting, etc.

(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. 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.

427, Coating Processes, appropriate subclasses, for processes of applying processing aid compositions to textile materials.

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

224+, and 357+, for textile materials carrying processing aid compositions. 508, Solid Antifriction Devices, Materials Therefor, Lubricant or Separant Compositions for Moving Solid Surfaces, and Miscellaneous Mineral Oil Compositions, for nontextile lubricant compositions

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.
