“…In the last 20 years, the production of textile flax fibres and tows has increased considerably, and in 2019, the Food and Agriculture Organisation of the United Nations (FAOSTAT, www.fao.org) estimated the total world production to be up to 1,000 k tons, led by France with 85% of the world textile flax fibre production (Gomez-Campos et al, 2021;Manian et al, 2021). The renewed interest in flax and other plant fibres used in areas other than textile applications, such as composite design and engineering, is due in part to global warming and the low environmental impact of flax fibre production, especially compared to synthetic fibres (Le Duigou et al, 2011).…”
