Embodiment

[0019] Such as figure 2 As shown, the method of spinning high-grade knitting yarn with flax long fiber is as follows:

[0020] (1) if image 3 As shown, after the commercially available flax long fiber is dried and pretreated at 135°C, it is dried and the water content is less than 1%, and the dried flax long fiber is put into a closed modified processor, After evacuating the modified processor, fill it with gaseous ammonia, so that the internal pressure of the modified processor is 3MPa, and then fill it with liquid ammonia, so that the liquid ammonia is immersed in all the long flax fibers and the internal pressure of the modified processor is 5Mpa, hold the pressure for 4 minutes Finally, liquid ammonia is removed, and then heating and vacuuming are carried out alternately to remove residual gaseous ammonia and liquid ammonia. When the pressure in the modified processor is heated until the pressure does not increase basically, the air pressure is balanced. Open the cover ...

Abstract

The invention provides a method for spinning high-grade knitting yarns by using long flax fibers. The method comprises the steps of: carrying out crystallization modification treatment on the long flax fibers, carrying out gilling, combing, slivering, drawing, roving, boiling-off, bleaching and spinning operations sequentially, and carrying out electronic yarn clearing and waxing simultaneously in a spooling process, thereby forming the knitting yarns. According to the method provided by the invention, the crystallization modification treatment is carried out on the long flax fibers, so that the fibers are soft in texture and have an improved uniformity for dry adjustment, therefore a foundation for spinning the high-grade knitting yarns is laid; and electronic yarn clearing and waxing operations are simultaneously carried out in the spooling process owing to the facts that the fibers are soft in texture and have an improved uniformity for dry adjustment after the crystallization modification treatment is carried out on the long flax fibers, therefore the spinning efficiency is improved, and the knitting yarn quality is improved.

Description

technical field [0001] The invention relates to a method for spinning high-grade knitting yarn with flax long fibers, belonging to the technical field of spinning. Background technique [0002] Linen fabric has excellent properties such as moisture absorption, breathability, anti-mold and anti-bacteria, anti-radiation, etc., and has been paid more and more attention by people. However, flax fiber is rigid, hard, rough, and poor in elasticity, and does not meet the requirements of soft and uniform knitting yarn spinning. Therefore, it is generally only spun into woven yarn, which limits the application of flax fiber and the development of flax products. . [0003] The traditional method of spinning flax long fiber into knitting yarn is as follows: figure 1 As shown, it includes needle-carding, combing, slivering, drawing, roving, scouring, bleaching, and spun yarn for flax long fibers to be spun into woven yarns, and then mechanical yarn clearing and air automatic blowing a...
