Working process of tow-to-yarn direct spinning of ramie

Abstract

The invention discloses a ramie draw-cutting spinning method, including ramie-softening working procedure, precombining working procedure, combing working procedure, gilling working procedure, roving working procedure, and spinning working procedure, it also includes a predraw-cutting working procedure and a draw-cutting working procedure arranged between the ramie-softening and precombining working procedures and the precombining working procedure is only one course of working procedure. The predraw-cutting and draw-cutting working procedures can achieve the effects of low fiber damage, high regularity of fiber length, high yield, and reducing ramie particles. The nonuniformity of fiber length in draw-cut ramie strips is about 20% lower than that in combed ramie strips, the super-long fiber content is largely reduced, and the number of ramie particles is remarkably reduced, thus assuring the improvement of ramie yarn quality. And at the same time, compared with loosening and combing machines, the draw-cutting device has simple mechanisms, small occupied land area and high output, thus able to shorten the whole flow of ramie spinning processing.

Description

Technical field: [0001] The invention relates to a yarn processing method, in particular to a ramie stretch-cut spinning processing method. Background technique: [0002] The existing ramie spinning processing flow is: [0003] Dry hemp → soft hemp process → opening process → hemp combing process → pre-combing process (2 steps) → combing process → needle carding process (3-4 steps) → roving process → spinning process. [0004] The problem that existing ramie spinning process flow exists is: [0005] After degumming to remove the colloid in the fiber, the ramie is relatively straight and neat, but the separation of the fiber is not complete, the fiber length is too long, and the difference is very large, so it needs to be loosened and combed in the subsequent process. In the hemp process, it is further separated and the ultra-long fibers are broken. In these processes, due to the strong carding action on the fibers by the use of combing needles and other parts, the fibers a...

AI Technical Summary

Problems solved by technology

[0007] It can be seen from the above that in the existing ramie processing procedures, the opening and carding procedures are the root causes of ramie grains, and there is no process at present that can completely and effectively eliminate the ultra-long fibers existing in ramie fibers. As a result, in the processing, due to the existence of hemp grains and ultra-long fibers, the processing and product quality are adversely affected
