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".

The mummies of ancient Egyptian pharaohs were wrapped in amazingly strong linen, making them completely preserved today. Linen fabric is known as "natural air conditioner". The heat dissipation performance of flax is excellent, because flax is the only bundle fiber among natural fibers. Bundle fibers are formed by the adhesion of flax single cells with the help of colloid. Because there is no more air left, the air permeability of flax fabric is as high as 25% or more, so its thermal conductivity (air permeability) is excellent. It can quickly and effectively reduce the skin surface temperature by 4-8 ℃.
