Comparing flax and hemp fibres yield and mechanical properties after scutching/hackling processing

Increasing the production of high-performance natural fibres that minimise their impact on environment is a challenge flax (Linum usitatissinum L.) cannot address alone. In traditional territories, hemp (Cannabis sativa can be complementary source high added value if yield long line maximised to levels equivalent one flax. The objective present work was establish process parameters maximising fibre using dedicated scutching and hackling devices. A lab-scale scutching/hackling device used sets which best improve as consequence tow fibres. Decreases in straw processing transfer beating speeds during were necessary so less aggressive Very yields obtained after at laboratory scale (18 % mass). These very results, combined field indicate productive these ones showed tensile properties completely suitable for textile use well load bearing composite materials. If potential mechanical morphological demonstrated lab-scale, this should improved industrial scale. Suggestions reach goal are provided prevent too transformation into tows keep maximum. When optimised device, it has providing amounts per hectare than with about 20 lower
