Flax fiber exists in the phloem tissue of hemp stem. After retting and degumming, part of the gum is removed, so that the adhesive fiber bundle is partially loose, and then it is processed into "beating flax", which is a process fiber composed of 10~20 single fibers.

Wool and linen interwoven cool fabric: flax fiber and wool textile are a new way to realize the lightness and coolness of wool fabric. Due to the large difference in fineness, elasticity, elongation, crimp and other properties between wool and flax fibers, it is difficult to control the process during blending, such as serious flying wool and winding roller, more broken ends, low production efficiency, large consumption, low spinning count, etc., wool and flax are often used to interweave to form a plain product of wool, hemp and weft. Due to the structure of double warp and single weft, the cloth surface is light, smooth, smooth and firm. The warp density of this wool and flax product is often higher than the weft density formed by stiff flax yarn. Most of the surface is wool fiber, so the future finishing will focus on wool fiber. Wool and linen interwoven cool fabric has the advantages of wool and linen, and has a good market in the field of re-use.
