The growth environment of flax determines its characteristics, such as roughness, broadness, high strength, good hygroscopicity, no sticking to the body, high rigidity, small winding degree, and difficulty in dyeing, which requires high processing technology for finished products. The flax fibers before treatment exist in the form of flax bundles, and the fibrils are bonded together with colloids, etc. After treatment, the colloids are removed, and the lignin, pectin, fat wax and other parts inside the fibers are removed, , the consumption is stronger, the spinnability is enhanced, and the flax fiber maintains the above characteristics, but also has a softer, more delicate and stronger consumption. Linen yarn is divided into dry spinning and wet spinning. Wet spinning products have natural luster, less hairiness, and high spinning count. The process is more complicated and costly than dry spinning products. Dry spinning products are difficult to spin to high counts, and the opposite sex is often added. With the help of fiber, it can be seen that wet spinning is better than dry spinning, which is not the same.
　　Flax is a cellulose fiber that grows between 37°-55° north latitude. my country&39;s production area is between 37°-47° north latitude, that is, Heilongjiang Province is my country&39;s main producing area, accounting for more than 95% of the national output. Flax has high requirements on natural conditions. It is suitable for planting on black soil, and the soil is rotated to maintain soil fertility. It needs sufficient water during the growth period, and the temperature gradually rises. The mature period has more than 12 hours of light, and the growth period is about 85 days. Weaving flax is obtained from bast tissue, and the hemp fiber is extracted through the process of retting, breaking stems, and beating hemp, and then through the processes of carding, roving, spun yarn and other spinning processes, yarns of various counts are presented. in front of you. Different methods are used to make flax, and the quality of flax is different. Among them, rain hemp is made from dew, sunlight and suitable temperature under natural conditions, and the earth is used as a bed. The colors of dark gray, variegated and rain hemp are the main colors of linen products.
　　The heat dissipation performance of linen is 5 times that of wool and 19 times that of silk. Under hot weather conditions, wearing linen clothing can make the skin surface temperature 3-4 degrees Celsius lower than wearing silk and cotton fabrics.
