SUMMARY
The main focus of this paper is the influence of processing parameters in enzymatic hemp separation on the fibre quality. The effect of NaOH-, EDTA- and Soda-pre-treatment, and enzymatic treatment with Lyvelin® was determined. The results show that processing parameters from, e.g., flax treatment can not easily be transferred to hemp, since there is a different pectin structure. NaOH treatment with low concentrations has only a very limited effect on fibre quality. In opposite to results known from flax, EDTA treatment has no effect on hemp separation. More successful is fibre pre-treatment by soda even in low concentrations. In addition the soda pre-treatment improves the efficiency of the subsequent enzymatic step.
