Flax is also called flax and flax. It is used for fiber separation, oil use, and fiber and oil dual-use. It is an annual herbaceous plant. Flax fiber exists in the phloem tissue of the flax stem. After soaking and degumming, part of the gum is removed, so that the adherent fiber bundles are partially loosened. The flax fiber is then rolled and beaten into “beaten flax”, which is 10 to 20 single fibers. Craft fibers composed of fibers. Due to its good hygroscopicity, fast moisture conduction and relatively thin diameter, it is one of the main fiber raw materials for summer clothes. Usually, cloth woven from flax fibers is called linen fabric.
After the fiber is harvested from flax, it is bundled into small handfuls for retting and degumming. The temperature of warm water retting should be controlled between 28 and 32°C. After about 100 hours, the fiber is taken out and the flax poles are put into an umbrella shape. Rain and dew retting is to lay the harvested hemp stems flat. After being soaked in rain and dew on grass or flax, it is fermented by mold under suitable humidity conditions. After 7 to 10 days, the retting stems are broken, the xylem and impurities are removed, the fibers are combed, and then the texture is pressed. Semicolon. The short hemp that is knocked out is called the second rough hemp.
Advantages:
Linen fabric has the functions of temperature regulation, anti-allergy, anti-static, and antibacterial. Because linen has good hygroscopicity, it can absorb an amount equal to its own weight. 20 times the moisture, so linen fabrics feel dry. Nowadays, the birth of anti-wrinkle, no-iron linen products and the emergence of blended products have further expanded the market of linen products. Internationally, linen is mostly woven on projectile looms. and rapier looms, products include delicate and elegant linen handkerchiefs, Shirt fabrics, crepe, fancy yarn products, sportswear and linen and wool blended products. Household products include: curtains, wall coverings, tablecloths, bedding, etc. Industrial products include: canvas, luggage tents, insulating cloth, Filter cloth and aviation products
Linen can be interwoven or blended with wool, polyester and other fibers to form unique, high-quality and affordable textile products.
Wool and linen intertwined cooling fabrics: The use of flax fiber and wool textiles is a new way to achieve lightness and cooling of wool fabrics. Due to the properties of wool fiber and flax fiber in terms of fineness, elasticity, elongation, curl, etc. The difference is large, and the process is difficult to control when blending, such as serious flying wool and top rollers, many broken ends, nodding, low production efficiency, high consumption, low spinning count, etc. Nowadays, wool and linen are often used for spinning. The plain weave products are interwoven with wool warp and hemp weft. Due to the structure of double warp and single weft, the cloth surface is light, smooth, and smooth and strong. The warp density of this wool and linen product is often higher than the weft density formed by stiff linen yarn. Most of the wool fibers appear, so the post-finishing process focuses on wool fibers. Wool and linen intertwined cooling fabrics have the advantages of wool and linen, and have a good market in the field of re-wear.
Linen fiber nonwovensCloth composites: Linen fiber nonwovens can be made through vacuum-assisted resin transfer molding (RTM)/ Unsaturated polyester composite materials, because flax is relatively cheap and has a smaller density than all inorganic fibers, while its elastic modulus and tensile strength are similar to those of inorganic fibers. It can partially replace glass fibers as reinforcing materials in composite materials. Flax Compared with glass fiber, carbon fiber, etc., the fiber is soft and can be Degumming treatment, choosing a reasonable carding process, and using acupuncture processing methods can produce non-woven reinforced fiber mats with a certain quantity and bulkiness that meet the requirements. At the same time, the fiber damage is small and the thickening effect is good. As a reinforcing material, it has a production process It is short, does not require weaving, and has low processing costs, which is conducive to energy saving and environmental protection.
