Flax, also known as crow flax and flax, is used for fiber separation, oil, and fiber oil dual-use, all of which are annual herbs. Because of good moisture absorption, fast moisture transmission and relatively thin diameter, it is one of the main fiber raw materials for clothes in spring and summer. Usually, the cloth woven from flax fiber is called flax fabric.

Linen cloth is woven by twisting flax into thread. Its surface is not as smooth as chemical fiber and cotton cloth. It has a vivid concave and convex texture. Artists often make use of this subtle and interesting material beauty. In addition to synthetic fibers, linen is one of the strongest textiles.
