Physical and Mechanical Characterization of Flax Fibers: From Elementary Fiber to Yarn
Summary
A French textile physics lab followed one industrial batch of flax from single fibres, through technical fibre bundles, to dry-spun yarns of four counts (83 to 111 tex) made after four gill-drafting passages. Single fibres were fine (0.22 tex) but very variable. Bundles longer than 150 mm were far stiffer (25.6 N/tex specific modulus) than bundles under 50 mm (14.4 N/tex). After the last drafting pass, mean fibre length was 110.9 mm and the airflow fineness index fell by about 18%. The finest yarn reached 17.1 cN/tex tenacity against 11.0 for the coarsest, so finer yarns came out stronger and stiffer. Limits: one flax batch only, high scatter (CV up to 67%), and no direct measurement of fibre alignment or twist.

Why it matters for Egyptian factories
Egypt grows flax and has a long linen tradition, and EU buyers want more linen and linen-blend home textiles and apparel. The paper gives spinners concrete numbers on how fibre length and drafting translate into yarn strength, which helps when choosing counts and preparation settings for flax yarns.
