Linen yarn is spun from flax fibres, and the fineness of linen yarn is typically measured in "Nm" (metric number). For example, pure linen yarn 36N (L36N) means that 1 kilogram of raw material can be spun into 36 lengths of 1,000 metres each.
Linen fabric offers excellent health benefits, with unique antibacterial properties. Flax, a member of the Lamiaceae family, emits a subtle fragrance. Scientific experiments using direct contact methods have proven that linen products have significant antibacterial effects, with inhibition rates of over 65% against international standard strains such as Pseudomonas aeruginosa and Candida albicans, and over 90% against Escherichia coli and Staphylococcus aureus. Linen fabric has an air permeability rate of over 25%, resulting in excellent heat conduction (breathability), and can rapidly and effectively lower the surface temperature of the skin by 4-8°C.
Linen fibres are smooth and straight, resembling segments of bamboo under magnification (50x), without the twists found in cotton or wool fibres. This feature makes it easier to remove dust or dirt from linen fabrics, as the particles have no place to lodge.
Linen fibres contain more than 18% hemicellulose, several times higher than cotton, which helps protect the skin from UV damage when worn. Linen fabric also reduces perspiration more effectively than other fabrics, with its water absorption rate being several times faster than satin, rayon, or even cotton.
Pure linen yarn comes in two types: short-spun and long-spun. Most long-spun linen yarn is automatically spun into cone-shaped spools without knots.
