The flax is also called as yamamai and flax, is divided into three types of fiber and oil, and is an annual herbaceous plant. The clothing is one of the main fiber raw materials of the clothing in spring and summer due to good moisture absorption, fast moisture conduction and relatively thin diameter. In general, a cloth woven from flax fibers is referred to as a flax fabric.
The linen fabric has natural air permeability, hygroscopicity, freshness, antibacterial property and other properties, and is popular with consumers all the time, but the linen is natural fiber, and the material has high toughness but no elasticity. Other fabrics can slowly recover to the original shape after being deformed, but flax cannot do the deformation, and only wrinkles once being deformed, so that the wearing performance of the fabric is seriously influenced by the characteristic.
