Example Embodiment

[0206] Example 1

[0207] A spinning process of a semi-continuous high-speed spinning machine, including glue supply, thread forming, spinning and winding. The spinning is completed by a spinning device 4, and the spinning device 4 includes at least one relative to the spinning The spinning roller 40 is arranged transversely on the operating surface 102 of the surface 101, and the filaments surround the spinning roller 40, and the spinning roller 40 rotates to complete the drafting, coagulation and deacidification in the spinning step.

[0208] The above scheme is the basic technical scheme of the present invention. In the process, the thread travels on at least one spinning roller 40 arranged transversely to the operating surface 102 of the spinning surface 101, which can realize spinning on the basis of a semi-continuous high-speed spinning machine. The speed is increased, and the spinning roller 40 can be rotated stably without shaking, which avoids the problems of intertwining...

Example Embodiment

[0209] Example 2

[0210] On the basis of Example 1, the specific process route is:

[0211] The viscose spinning stock solution is supplied with glue through the rubber supply tube 202, and the flow is controlled by the metering pump 201, and then enters the spinneret 301 through the filter 203. The spinneret on the spinneret 301 ejects the filament, and the filament enters the tube to form After the device 303 or the bath forming device 302 is solidified and formed, the formed thread travels to the spinning roller 40 arranged transversely to the operating surface 102 of the spinning surface 101. The thread surrounds the spinning roller 40 and is completed under the rotation of the spinning roller 40 The drawing, coagulation and deacidification in the spinning step. In the process of drafting, coagulation and deacidification, the thread is also washed by the washing device 42. The thread is discharged from the spinning roller 40 and passes through the hopper 50. , Falling into t...

Example Embodiment

[0212] Example 3

[0213] On the basis of embodiment 1, preferably:

[0214] The semi-continuous high-speed spinning machine includes a frame 1, and the two ends of each spinning roller 40 are respectively fixed above the two sides of the frame 1 and connected to a driving device to rotate.

[0215] Furthermore, each of the spinning rollers 40 is respectively connected with a driving device to realize independent and real-time speed regulation rotation.

[0216] The above-mentioned solution can more easily control the rotation speed of each spinning roller 40, realize real-time online speed adjustment, and can also change the specifications and varieties of the thread online without changing gears and other transmission components.

Abstract

The invention relates to a spinning technology of a semi continuous high speed spinning machine, belongs to the technical field of semi continuous spinning machine spinning, and comprises the steps of glue supplying, filament forming, spinning and winding, wherein the spinning is accomplished by a spinning device which comprises one or more spinning rollers arranged on an operating surface corresponding to the spinning surface, the filament winds around the spinning roller, the drafting, solidification and deacidification of the spinning step are accomplished under the rotation of the spinning roller. According to the spinning technology provided by the invention, the problems that the spinning speed can not be accelerated and dual attention to the working efficiency and the product quality cannot be given, caused by the insufficiency reaction of the semi continuous high speed spinning machine filament, are solved, the changing of the spinning roller distribution direction enables the spinning machine to accelerate spinning speed and reserve the structure of other parts of the conventional device, the filament to walk farther, and the reaction of the filament and the acid bath to be more efficient, both the working efficiency and the product quality are considered.

Description

technical field [0001] The invention relates to a spinning process, more specifically, the invention relates to a spinning process of a semi-continuous high-speed spinning machine, which belongs to the technical field of semi-continuous spinning machine spinning. Background technique [0002] Pure methyl cellulose is extracted from cellulose raw material, called pulp. Treat with caustic soda and carbon disulfide to obtain orange-yellow cellulose xanthate sodium, and then dissolve it in dilute sodium hydroxide solution to become viscous spinning stock solution, called viscose. After the viscose is filtered, matured and defoamed, it is wet-spun, and the coagulation bath is composed of sulfuric acid, sodium sulfate and zinc sulfate. Sodium cellulose xanthate in the viscose reacts with sulfuric acid in the coagulation bath to decompose, and the cellulose is regenerated and precipitated. The obtained cellulose fiber becomes viscose fiber after washing, desulfurization, bleaching...
