Flax fiber is the first natural fiber used by human beings. It is the only bundle plant fiber among the natural fibers. It has a natural spindle structure and unique pectin beveled holes. The resulting excellent moisture absorption, breathability, anti-corrosion, bacteriostasis, low static and other characteristics make flax fabric a fabric that can breathe naturally, known as the "fiber queen".

Long term exposure to ultraviolet radiation can damage human body. The hemicellulose contained in flax textile products is the best material to absorb ultraviolet rays. Hemicellulose is actually immature cellulose. The hemicellulose content of flax fiber is more than 18%, which is several times higher than that of cotton fiber. When it becomes clothing, it can protect the skin from ultraviolet rays.
