Flax fiber is the oldest textile fiber in the world, and fabrics made from flax fiber are used in a wide range of applications as industrial goods such as clothing fabrics, upholstery fabrics, tablecloths, bedding, and automotive supplies. With the emergence of new varieties, new technologies, new spinning methods, new weaving methods and new finishing processes, the development momentum of the linen products industry is getting better and better. The main production areas of flax products are mainly France, Belgium and Netherlands, and although the planting area of flax in China is relatively high, the output of flax fiber only ranks sixth.
Linen yarn fiber fabric is known as "air conditioning". Linen yarn has good heat dissipation performance because linen yarn is a bundle of fibers in the fiber. Bundle fibers are formed by the bonding of flax yarn single cells with the help of gum, because there is no more air retention conditions, and its thermal conductivity (air permeability) is good.
