Embodiment 1

[0026] Such as figure 2 Shown, a kind of dry-spinning method of flax short fiber spinning high-count yarn provided by the invention, its steps are:

[0027] The first step is to use the flax staple fiber that falls after combing the original flax fiber as the raw material for dry spinning;

[0028] The second step is to carry out crystal transformation modification treatment on flax staple fiber. During the crystal transformation modification process, the modified medium is recycled, which is a pollution-free and zero-emission treatment process;

[0029] combine image 3 , the specific steps of the crystal transformation modification treatment are:

[0030] Carry out drying pretreatment to the flax staple fiber, make it dry and free of moisture, put it into a closed modified kettle, after vacuuming the modified kettle, first fill it with ammonia gas to make the pressure in the modified kettle greater than 3MPa, Subsequently, fill in liquid ammonia to make it immerse all fl...

Abstract

The invention provides a dry spinning method for spinning flax short fiber into high count yarn, comprising the following steps: step 1, original flax fiber is combed to enable flax short fiber to fall down, and then the flax short fiber is used as the raw material for dry spinning; step 3, crystallized and modified flax short fiber obtained in the step 1 is subjected to flax assorting, and the crystallized and modified flax short fiber is spun into flax rough yarn through 3-4 times of gilling, combing, slivering, drawing and roving procedures; step 4, the flax rough yarn is dry-spun into high quality and high count flax fine yarn by a dry spinning frame; the drying spinning method is characterized in that a step 2 is carried out between the first step and the third step; and step 2, the flax short fiber is subjected to crystallization and modification treatment. The dry spinning method has the advantages that the dry spinning method can be used for spinning flax short fiber into 50 metric count according to the fiber proportion which is adopted by the traditional dry spinning method used for spinning flax short fiber into 36 metric count flax yarn, and the technological and process innovation that low-quality flax short fiber can be spun into high quality and high count flax yarn is realized; and the caustic soda and glacial acetic acid treatment adopted in the traditional dry spinning method is replaced by the crystallization and modification treatment, so that no exhaust gas and liquid waste are generated in the whole technological process.

Description

technical field [0001] The invention relates to a flax fiber spinning method, in particular to a dry spinning method for spinning high-count yarns of flax short fibers, and belongs to the field of high-end textile materials. Background technique [0002] Such as figure 1 As shown, the traditional flax short fiber dry spinning method is to use the short fiber that falls after the original flax fiber is combed as the raw material for dry spinning. After the slivering, drawing and roving processes are spun into flax rovings, the flax rovings are spun into flax spun yarns by dry spinning frame. [0003] The flax spun yarn spun by the above-mentioned traditional dry spinning method has low count, uneven evenness and rough hand feeling, so it cannot be used for high-end textiles. Contents of the invention [0004] The purpose of the present invention is to provide a dry spinning method capable of spinning low-quality flax staple fibers into high-quality and high-count flax yar...
