Correlating Crystallite Orientation Dispersions with Wet Spinning Yields in Long Staple Flax
Narrow crystallite orientation dispersion below 14 degrees FWHM maximizes wet spinning yields and fine count limit up to Nm 60 in long staple flax.

Yarn Fineness
Metric measurement defines the length of a single gram of fibre based on the number of metres per unit of mass. The nm 60 yarn provides a specific count where sixty metres of the single strand weigh exactly one gram. This classification determines the physical diameter of the product after spinning process completion at the mill.
It serves as the standard notation within European and global trade for identifying the thickness of linen produced from flax fibre. Industry production records define this count by calculating the ratio of mass to total length during the finishing stage.
Spinning Specification
High spinning precision allows a mill to achieve such fine gauge through consistent drafting of the flax rovings. Operators adjust the distance between rollers to ensure uniform diameter throughout the final bobbin weight. Variations in humidity inside the facility alter the moisture regain of the natural fibres which influences the measured mass.
Quality inspectors monitor these parameters before transferring the material to the warping or weaving department. Each reel undergoes automated testing to verify the target density matches the technical request of the buyer. A deviation exceeding the allowed tolerance in the output forces a reassessment of the drafting machinery settings.
Commercial Application
Fabric manufacturers select this specific fineness to produce lightweight apparel textiles that require durability along with a refined drape. Fine counts allow for higher density in the reed of the loom which creates a smoother hand in the finished cloth surface. Export documents reference this numerical count to establish the value of the shipment based on the weight of the base material.
Precision in the spinning phase ensures that the final cloth remains consistent across large production batches. Accurate density control guarantees the integrity of the material performance under tension during industrial garment assembly.
