The combination of utilisation of fibres from industrial hemp waste and degumming using deep eutectic solvents can contribute to a more sustainable textile industry. This study therefore evaluates the effect of deep eutectic solvent treatment on fibres from Finola hemp grown for food production. A deep eutectic solvent (DES) consisting of choline chloride and urea with molar ratio 1:2 was chosen as well as a microwave-assisted treatment method to replace the traditional oil bath which consumes more energy and time. The results showed that the treatment had a degumming effect on the fibres. It was indicated by a significant smaller diameter. After evaluation, the most efficient treatment combination was concluded to be treatment at 100 W/g with bath ratio 1:20 (weight: volume) and 12 heating cycles consisting of 0.5 min microwave heating with 1 min between. The fibres had a significant reduction in mean length, from 37.8 mm to 29.8mm. The other results were however deemed to outweigh the length reduction.
