 CHEMICAL FEATURES IN THE MANUFACTURE OF ARTIFICIAL FILAMENTS, THREADS, FIBRES, BRISTLES, OR RIBBONS; APPARATUS SPECIALLY ADAPTED FOR THE MANUFACTURE OF CARBON FILAMENTS [2]
 

Notes

(1)

 Attention is drawn to the Note following the title of class D 01.

(2)

 Processes using enzymes or micro-organisms in order to:
 

(i)

 liberate, separate or purify a pre-existing compound or composition, or to
 

(ii)

 treat textiles or clean solid surfaces of materials
 

are further classified in subclass C 12 S. [5]
