Wet spinning method of low-proportion high-spun flax macrofiber

Abstract

The invention provides a wet spinning method of low-proportion high-spun flax macrofiber, which comprises the steps of: a first step, combing original flax fiber to obtain flax macrofiber; a third step, carrying out hemp proportioning on the flax macrofiber obtained after crystal transition modification in a former step, gilling, paralleling and spinning by a roving process to obtain flax roving; and a fifth step, carrying out wet spinning on the flax roving obtained after water blanching in a former step by a wet spinning frame to obtain the flax yarn. The wet spinning method is characterized in that a second step of carrying out crystal transition modification treatment on the flax macrofiber is performed between the first step and the third step, and a fourth step of carrying out water blanching on the flax roving is performed between the third step and the fifth step. The method has the advantages that the utilization ratio of the flax macrofiber is greatly improved and reaches more than 70%, and the material resources are saved; high-count linen yarn can be spun according to the fiber proportion of the traditional wet spinning method; and the water blanching replaces the scouring blanching in the traditional wet spinning method, so that the process is simplified, the energy sources are saved and the cost is lowered.

Description

technical field [0001] The invention relates to a flax fiber wet spinning method, in particular to a low-profile and high-spin long flax fiber wet spinning method, which belongs to the field of high-end textile materials. Background technique [0002] Such as figure 1 As shown, the traditional flax long fiber wet spinning method is to use the flax long fiber obtained after carding the original flax fiber as the raw material for wet spinning, and the flax long fiber is spun into flax through the processes of blending, needle combing, slivering, drawing, and roving. After roving, the flax roving is scoured and bleached, and then wet spun into flax spun yarn by wet spinning frame. Among them, needle combing, slivering and drawing are generally carried out on a combing machine. [0003] The disadvantage of adopting the above-mentioned traditional wet spinning method is that the utilization rate of flax long fibers is only about 49%, and the flax spun yarns spun out have low co...
