Note(s)

In this class, the following words are used with the meanings indicated:

  1. "fibre" means a relatively-short, elongated member of natural or artificial material;
  2. "filament" means an endless or quasi-endless, elongated member of natural or artificial material;
  3. "yarn" means a unitary assembly of fibres, usually produced by spinning.
  4. "thread" means an assembly of yarns or filaments, usually produced by twisting;
