DEFINITION

Classification: 428/397

(under subclass 364) Product claimed in terms of the particular shape of a section transverse to the longitudinal axis thereof or wherein the particular shape or arrangement of the constituent thereof is claimed and wherein the transverse section is other than circular and of uniform diameter.

(1) Note. See (1) Note under subclass 364 for placement of a coated rod, strand, fiber, etc.

(2) Note. A rod, filament or fiber with surface deformities, e.g., ridges, furrows, etc., is included under this definition and will be found in subclass 400.

373+, for a conjugate or composite or collateral fiber or filament of side-by-side or other nonuniformly circular configuration.

SEE OR SEARCH CLASS 8, Bleaching and Dyeing; Fluid Treatment and Chemical Modification of Textiles and Fibers, for the process provided for in that class for preparing a fiber or monofilament of particular cross section;

112, for the process of treating a strand or fiber to improve its felting properties; subclasses 114+ for a process of treating a rod or strand to produce an ornamental effect (e.g., creping, etc.); subclasses 115.51+ for the process of chemically modifying a fiber and the corresponding product and subclass 130.1 for the process of swelling or plasticizing a synthetic strand or fiber and the corresponding product.
