DEFINITION

Classification: 427/249.3

Fiber or fibrous web or sheet base: (e.g., strand, filament, fabric, cloth, etc.)

(under subclass 249.1) Process wherein the carbon or carbide coated base is a fiber, fibrous web, or sheet.

(1) Note. A fiber is considered to be a relatively short, slender, flexible element of macroscopic size and finite length and having a width and thickness of the same order of magnitude. A fiber is generally of staple length to facilitate its being spun, twisted, or otherwise secured together into a composite strand but may be of shorter length requiring bonding, felting, or matting to form a strand or layer. It may be of animal (e.g., wool, rabbit hair, etc.), vegetable (e.g., cotton, jute, hemp, etc.), or mineral (e.g., asbestos, glass, metal, etc.) origin and may be either natural, modified, or synthetic.

(2) Note. A strand is considered to be a relatively slender and flexible element having a width and thickness of the same order of magnitude and a length which is either (a) indeterminate or (b) coextensive with the length or width of a sheet or layer with which it may be associated. A strand may be a monofilament or it may include either a plurality of filaments or fibers disposed in parallelism (e.g., tow, etc.) or constituent fibers and/or filaments knitted, plaited, braided, twisted, interlaced, interlocked, or otherwise secured together to form a unit such as roving, thread, yarn, cord, rope, or cable.

(3) Note. A filament is considered to be a fine threadlike body or structure whose width and thickness are of the same order of magnitude.

(4) Note. A fibrous web is considered to be a sheet of random or organized fibers having length and width each greater than its thickness and with at least its longitudinal dimension indeterminate.

(5) Note. A fabric is used in the manufacture of household furnishings (e.g., draperies, upholstery, etc., and roofing, clothing, tires, etc.) and is generally claimed as a textile, cloth, or fabric.
