Description: An experimental study was carried out using a drum carder to separate fibre from decorticated hemp material. The effectiveness of carding machine on fibre separation was investigated for three different numbers of turns of the licker-in cylinder and five different feeding masses. After carding, different fractions (fibre, core, fibre attached with core, waste) of the hemp material were manually separated and measured before and after carding. Based on those measurements, the effectiveness indicators were determined. The indicators included fibre purity, detaching effectiveness, and waste production. Highest fibre purity was found for maximum number of turn and for top amount of mass. Peak detaching effectiveness was noticed for highest number of turn and for maximum amount of mass. In case of waste fractions, minimum value was noticed for least number of turns. Only turn played significant role as a carding parameter for detaching effectiveness and waste production.
