Fig. 2. Microscopy images of hemp fibres. (a) Fibre strips from the un-retted un-processed stems before acid hydrolysis, (b) un-retted un-processed fibres after acid hydrolysis—the arrow shows a long fibre still apparently intact after acid hydrolysis, (c) decorticated fibres from un-retted stems before acid hydrolysis, (d) decorticated fibres from un-retted stems after acid hydrolysis—the arrow points a shive, (e) decorticated and carded fibres from un-retted stems before acid hydrolysis, and (f) decorticated and carded fibres from un-retted stems after acid hydrolysis. Scale bars equal 5mm.
