Chemical processing is essential for proper separation of individual bast fibres from fibre bundles. Hemp fibres were subjected to different scouring agents and their effect on tensile strength, elongation, fibre fineness and per cent fibre weight loss was studied. Alkalis were found effective in improvement of fineness but alkali scoured fibres exhibited less tensile strength in comparison to acid scoured fibres. Fibres of selected scouring method were bleached to improve their appearance, colour and softness. After each chemical processing, fibre fineness and whiteness value increased but tensile strength and elongation decreased gradually.Keywords
