Notes[n] D01:
  • 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.
D01B MECHANICAL TREATMENT OF NATURAL FIBROUS OR FILAMENTARY MATERIAL TO OBTAIN FIBRES OR FILAMENTS, e.g. FOR SPINNING (crude extraction of asbestos fibres from ores B03B; apparatus for retting D01C).
Notes[n] D01B:
  • Attention is drawn to the Note following the title of class D01 .
D01C CHEMICAL OR BIOLOGICAL TREATMENT OF NATURAL FILAMENTARY OR FIBROUS MATERIAL TO OBTAIN FILAMENTS OR FIBRES FOR SPINNING; CARBONISING RAGS TO RECOVER ANIMAL FIBRES.
Notes[n] D01C:
