Production of Long Hemp Fibers Using the Flax Value Chain

Hemp is finding a strong renewal of interest in the production fine fibers for garment textiles. This resource long-line would come as complement to highly demanded flax fibers, whose large north-west Europe cannot be extended. In Normandy, where complete industrial value chain exists flax, it intended adapt hemp, and this was demonstrated from field scutched with chain. region, early harvesting necessary leave enough time dew-retting permit dry storage stems before mid-September. An early-flowering variety (USO-31) harvested using dedicated hemp equipment obtain 1 m parallel aligned windrow that can further processed by equipment. The scutching process well fiber’s morphological mechanical properties were particularly studied. Adapted parameters reduced advancing speed beating turbine velocity led long fiber yields about 18% stem mass. Stem reaching 6 tons/ha leading 1.1 fibers. tensile sufficient textile applications, their thickness after hackling range suitable yarns. Compared other crops grown produced 2020 case study provides good incomes farmer, higher than traditional such wheat or barley, results should encourage farmers grow purposes.
