Hemp bast fibre is produced in the phloem tissue of the stem. Consequently, the plants are grown close to each other so that branching is limited and long slender stems are produced (Fairbairn, 1976). The properties of hemp fibre, its harvesting and processing have been described by Judt (1995) and Clarke (1981: p. 150). Two types of fibres are present in cannabis stems—bark or bast fibres (23–28% by weight) and core fibres (75–70%). The two vary in their physical characteristics and chemical composition (Judt, 1995).
