Flax, also known as crow and flax, can be divided into three categories: fibre, oil and fibre-oil. They are annual herbs. Because of its good hygroscopicity, fast moisture conduction and relatively fine diameter, it is one of the main fiber materials for clothes in spring and summer. Usually, the fabric woven from linen fibers is called linen fabric.

Flax fabrics have the functions of temperature regulation, anti-allergy, anti-static and anti-bacterial. Because flax has good moisture absorption and can absorb 20 times its own weight of water, it feels dry. Nowadays, the birth of wrinkle-proof and non-iron flax products and the emergence of blended products have further expanded the market of flax products. In the world, flax weaving is mostly shuttle looms and rapier looms. The products include fine and elegant linen handkerchiefs, shirt materials, crepe, fancy yarn products, sportswear and flax wool blended products. Household products include curtains, wall cloths, tablecloths, bedding and so on. Industrial products include canvas, baggage tents, insulation cloth, filter cloth and aviation products.

Flax can be interwoven or blended with wool, polyester and other fibers to form textile products with unique style and good quality and low price.

Cool wool-linen interwoven fabrics: Flax fibers and wool textiles are new ways to realize the lightening and cooling of wool fabrics. Because wool and linen fibers differ greatly in fineness, elasticity, elongation, crimp and other properties, the blending process is difficult to control, such as serious flying wool and winding rollers, broken ends, falling flax, low production efficiency, high consumption, low spinning count, etc. Now wool and linen are often interwoven to form plain wool, warp and weft products. The surface is light, smooth and firm. The warp density of wool and linen yarn is usually higher than that of stiff linen yarn, and wool fibers are mostly displayed on the fabric, so the finishing is focused on wool fibers. Cool wool-linen interwoven fabrics have the advantages of both wool and flax, and have a good market in the realm of re-wear.

Flax fiber nonwovens composites: Flax fiber nonwovens/unsaturated polyester composites can be fabricated by vacuum-assisted resin transfer molding (RTM). Because flax is relatively cheap, its density is smaller than all inorganic fibers, and its elastic modulus and tensile strength are similar to inorganic fibers, glass fibers can be partially replaced as reinforcing materials in the composites. Compared with glass fibers and carbon fibers, flax fibers are soft. Through proper degumming treatment and reasonable carding process, needle-punching processing method can produce non-woven reinforced felt with quantitative and fluffy degree. At the same time, the damage of fibers is small and the effect of thickening is good. As a reinforcing material, flax fibers have short production process, no need of weaving and processing.  The advantages of low cost are conducive to energy saving and environmental protection.
