Note(s)

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

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