Problems solved by technology

[0006] In order to solve the defects that the processing equipment used in the existing ramie opening process and carding process causes a sharp increase in ramie grains and difficult elimination of ultra-long fibers, and the invention patent of the simple roller stretching method that the inventor has applied for There are many problems in doubling yarns, the present invention further provides a more complete processing scheme, that is, to provide a roller-needle plate hybrid ramie stretch-cutting spinning equipment, thereby forming a stretch-cutting process to replace the existing The unique opening process and combing process have created good conditions for improving the quality of ramie products

Embodiment

[0023] The ramie refined hemp produced in Hunan is adopted, and its properties are shown in Table 1:

[0024] Table 1 Performance indicators of refined hemp

[0025] average length

[0026] After adopting the roller needle-plate mixed type ramie stretch-cutting spinning equipment of the present invention to above-mentioned lean hemp raw material to process, the quality performance index of its semi-finished product and finished product is as shown in table 2 and table 3:

[0027] Table 2 Comparison of quality indicators between stretch-cut sliver and carded hemp sliver (stretch-cut distance is 110mm)

[0028] As can be seen from Table 2, the length uniformity of the fibers after stretch cutting is significantly improved, especially the content of ultra-long fibers above 120mm is significantly reduced, and the hemp grains in the fiber strips are greatly reduced than those in the carded hemp strips; although the strength is reduced, However, since the weaker fibers ar...

Abstract

The present invention belongs to the field of textile engineering technology. It relates to a roller stave mixed type ramie draft-cutting spinning equipment, and it is formed from roller draft cutting device and stave device.

Description

Technical field: [0001] The invention belongs to the field of textile engineering, and relates to a roller needle-plate hybrid ramie stretch-cut spinning device. 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] In the existing ramie spinning process, the softening process is mainly to loosen and soften the dry hemp by kneading it. The softening machine used in this process is generally the equipment of the CZ141 type; part of the extra-long fiber, and preliminarily loosen the dry hemp. The opening machine used in this process is generally a type of equipment such as C111B, FZ001 or FZ002; the carding process is mainly to further refine the fiber after opening. The carding machine used in this process is generally a CZ191 type of equipm...
