The costs of the fibre pulping of hemp fibres have clearly to be reduced for competition reasons. Therefore investigations are carried out at the ATB Potsdam --Bornim for the optimization of the rebound stress. Results from tests with green hempshows, that a high yield of fibres >28% and a defective ratio of the fibre output of only 1 to 2% are possible. From the complete part of the shabbies >50% are given off in a one run.
