Embodiment 1

[0136] A spinning process of a semi-continuous high-speed spinning machine with four spinning rollers, including glue supply, filament molding, spinning and winding, and the spinning is completed by a spinning device 4, which includes four The spinning roll 40 that is arranged laterally with respect to the operating surface 102 of the spinning surface 101, the four spinning rolls 40 are respectively a drafting roll 404, a coagulating roll 405, an acid removal roll 406 and a godet roll 407, and the filament 8 Around the drafting roll 404, the coagulation roll 405, the acid removal roll 406 and the godet roll 407 in turn, the drafting, coagulation and deacidification in the spinning step are completed under the rotation of the spinning roll 40; the drafting roll 404, The speed control of coagulation roll 405, acid removal roll 406 and godet roll 407 is the following combination:

[0137] The speed control of the drafting roller 404 is 30r / min; the speed control of the coagulatio...

Embodiment 2

[0146] On the basis of embodiment 1, concrete process route is:

[0147] The viscose spinning stock solution is supplied with glue through the rubber supply pipe 202, the flow rate is controlled by the metering pump 201, and then enters the spinneret 301 through the filter 203, and the spinneret on the spinneret 301 sprays out filaments, and the filaments enter the tube to form After the device 303 or the bath forming device 302 is solidified and formed, the formed filaments travel to the spinning roll 40 arranged transversely relative to the operating surface 102 of the spinning surface 101, and the filaments surround the spinning roll 40 and are completed under the rotation of the spinning roll 40. Drafting, coagulation and deacidification in the spinning step, in the process of said drafting, coagulation and deacidification, the silk sliver is also washed by water washing device 42, and the silk sliver is exported from the spinning roller 40 and passes through the funnel, I...

Embodiment 3

[0149] On the basis of embodiment 1, preferred:

[0150] The semi-continuous high-speed spinning machine includes a frame 1, and the two ends of the four spinning rollers 40 are respectively fixed above the two sides of the frame 1, and are connected with a driving device to rotate.

[0151] Furthermore, the four spinning rollers 40 are respectively connected with the driving device, which can realize independent and real-time speed-adjusted rotation.

[0152] The above solution can more easily control the speed coordination of each spinning roller 40, and can realize real-time online speed regulation, and also can change the specifications and types of filaments online without replacing gears and other transmission components.

Abstract

The invention relates to a spinning technology of a four-spinning-roller semi-continuous high-speed spinning machine, and belongs to the technical field of semi-continuous spinning machine spinning. The spinning technology comprises glue supply, thread forming, spinning and winding, wherein spinning is finished through a spinning device, the spinning device comprises four spinning rollers transversely arranged opposite to the operation surface of a spinning surface and are surrounded by threads, and drafting, solidification and acid removing are finished through rotating of the spinning rollers in the step of spinning. The spinning technology of the four-spinning-roller semi-continuous high-speed spinning machine solves the problems that a semi-continuous spinning machine in the prior art is insufficient in thread reaction, and therefore the spinning speed can not be increased, and production efficiency and product quality can not be given consideration to; the arrangement directions of the spinning rollers can be changed to increase the spinning speed of the spinning machine without changing structures of other parts of the original four-spinning-roller semi-continuous high-speed spinning machine, the threads can move farther and can more sufficiently react in an acid bath, and both production efficiency and product quality are given consideration to.

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 with four spinning rollers, belonging 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, des...
