 Note

 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.
