Problems solved by technology

[0006] However, there is a major problem in the existing flax spinning process: the combed long flax and machine short flax need to be processed separately after the combing process, so that the flax spinning must be completed by two sets of systems. Considering it from a different perspective, the manpower, equipment costs and equipment occupied by the two systems are much more than that of the one processing system.
[0008] Therefore, the existing flax spinning system equipment has poor versatility, long process flow, and relatively large damage to fibers during the processing. The existence of these problems not only reduces the benefits and efficiency of flax spinning, but also restricts the production of flax spinning to varying degrees. Change and development of technology and equipment

Embodiment 1

[0025] The flax imported from France is used as raw material, and processed through the following procedures:

[0026] Hemp→drawing and cutting process→needling process (1-2 steps)→combing process (→re-combing process)→pinning process (3-4 steps)→roving process→scouring and bleaching process→wet spinning Spinning process.

[0027] Table 1 shows the comparison of the raw material performance index and the drawing strip performance index.

[0028] Table 1 Performance comparison of hemp and stretch cut strips

[0029] The results in Table 1 show that after stretching and cutting, the strength and splitting degree of the spun hemp are improved, the length meets the requirements of short spinning, and the uneven strength and length are reduced. These changes are beneficial to the post-spinning process. carried out.

Abstract

The invention relates to flax tow-to-yarn direct spinning method. It includes the following steps: combing, gilling, roving, boiling off, bleaching, spinning, and tow-to yarn direct spinning. The invention has the advantages of little fiber damage, high regularity, increasing flax yarn quality, simplifying original spinning system, shorting process scheme.

Description

technical field [0001] The invention belongs to the field of textile engineering, in particular to a flax stretch-cut spinning processing method. Background technique [0002] Existing flax spinning (wet method) is divided into long hemp spinning and short hemp spinning. Generally, combing machine is used to comb the primary processed flax. Its main function is to comb out flax from the flax. Long, neat, high-strength combed hemp, and the hemp is further split into finer process fibers to remove some non-spinnable impurities. At the same time, combing also produces waste that accounts for nearly 50% of the total raw material. Hemp is machine short hemp. Long linen and short linen separated after combing enter the long spinning and short spinning systems respectively. [0003] In long hemp spinning, the combed long hemp is first passed through the sliver forming machine to obtain continuous slivers, and then enters the needle carding process, so that the slivers are merged ...
