COOPERATIVE PATENT CLASSIFICATION
​
D06L
DRY-CLEANING, WASHING OR BLEACHING FIBRES, FILAMENTS, THREADS, YARNS, FABRICS, FEATHERS OR MADE-UP FIBROUS GOODS; BLEACHING LEATHER OR FURS [2017-01]
NOTES

  • In this subclass, the term "bleaching" also covers "optical bleaching".
  • This subclass does not cover treatment of textiles by purely mechanical means, which is covered by subclasses D06B, D06C or D06F.
