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 flax fiber is straight and smooth. In the 50 times magnified projection, it looks like bamboo without distortion of cotton and wool fibers. This feature makes the textiles with fine dust or dirt easy to remove because the dust cannot find a hiding place.
