Problems solved by technology

[0003] The strength of viscose fiber produced by the above process is generally about 2.2CN / dtex, and it is easy to elongate under a small load, so its shrinkage rate is large, easy to wrinkle, easy to deform, etc. Weft or mixed with other synthetic fibers, which greatly limits its application

Abstract

The invention relates to a viscose filament yarn semi-continuous spinning machine and a spinning process thereof. The viscose filament yarn semi-continuous spinning machine comprises a frame. A glue spray device, a lower solidifying roller and an upper solidifying roller are arranged on the frame. An upper drafting disc is coaxially arranged at the end part of the upper solidifying roller and a lower drafting disc is coaxially arranged on the lower solidifying roller. Since the upper drafting disc and the lower drafting disc are arranged for drafting nascent filaments to break down a large draft multiple into a plurality of small draft multiples for times of drafting, the invention has the advantages that the one-step large-multiple drafting is avoided, the situation that the fiber elongation is reduced because the filaments are damaged is avoided, viscose filament yarns with high strength and elongation which satisfies process requirements can be spun, the strength of the viscose filament yarns can reach above 2.5CN / dtex and the viscose filament yarns can be used as both the warps and the wefts of fabrics.

Description

technical field [0001] The invention relates to a viscose filament production equipment, in particular to a viscose filament semi-continuous spinning machine and a spinning process thereof, belonging to the technical field of spinning. Background technique [0002] At present, viscose filament semi-continuous spinning machine, such as figure 1 Shown, generally comprise frame 1, be provided with viscose pipe 2, metering pump 4, filter 6, bath 13, spinneret 14, lower coagulation roller 7 and upper coagulation roller 9 on the frame 1, upper coagulation roller 9 The end of the upper drafting disc 10 is provided, and the viscose from the viscose pipe 2 enters the filter 6 after being metered by the metering pump 4, and the filtered viscose is ejected from the spinneret 14, and is solidified in the bath 13 to form Primary filaments, the primary filaments are wound to the upper drafting disc 10 through the acid scraping rod 12, then wound from the upper drafting disc 10 to the upp...
