A product of substantial length and relatively small cross-section consisting of fibres and/or filament(s) with or without twist.
Note 1: Assemblies of fibres or filaments are usually given other names during the stages that lead to the production of yarn, e.g., tow, slubbing, sliver, or roving. Except in the case of continuous-filaments or tape yarns, any tensile strength possessed by the assemblies at these stages is generally the minimum that can hold them together during processing.
Note 2: Staple, continuous filament, and mono-filament yarns are included.
Note 3: No distinction is made between single, folded and cabled yarns.
Note 4: Zero-twist continuous filament yarns are included.
Note 5: Zero-twist and self-twist staple yarn are included.
Note 6: By the definition of fibre and filament, paper, metal, film and glass yarns are included.

A continuous strand of textile fibers that may be composed of endless filaments or shorter fibers twisted or otherwise held together. It may be made up of vegetable (linen, hemp, jute, sisal, ramie, cotton), animal (wool, mohair, silk), or artificial fibers (gold, silver and other metals rayons, nylon, orlon). Yarns are utilized in making fabric. Yarn is charachterized by its composition, its thickness (or grist or count), number of strands (or plies), direction and degree of twist, and the color.
