Description

The object of the present invention is to provide an improved method for producing artificial fibers of any length and suitable for spinning in the same way. What kind of cotton is used? If cotton is drupu fiber or for n-denn blend B with other fibers.

According to the present invention. The discharging solution from the filter is interrupted by spraying some kind of liquid in it, in order to break the discharged drinks; the composition of the outlet from the holes, 11 enters the coagulum bath in the form of individual fibers of a certain length.

The method can be carried out with the nomosh annarat shown in the drawing.

FIG. 1 shows a vertical section of an annarat. FIG. 2 is a view of the apparatus at a right angle to FIG. 1 and FIG. 3 - vpd apparatus above. A nozzle with an outlet and a subdivision for a measuring cell fiber can be brought to the upper non-working position, and the GHTs are shown in this polo / capy for better clarification of the proposed co-structure. FIG. 4 represents

It is a general view of the apnarata, partly in section, depicted in conjunction with a coagulum bath and a pump.

As this is a video from the drawing, the device consists of a round wave 5, the diaphragm 6 is attached to the bottom, a spraying finger with a finger or a protrusion 7 resting on a rotating Cam Ibuy 8 with many cams. When the cam washer is 8, the diaphragm 6 is raised and lowered and acts as a pump.

A chamber 9 is formed between the D1 afragma and the bottom of the vapna 5, which connects to the tube 10 supplying liquid through the automatic check valve 11 and the passage 12. With the mentioned chamber 9, the passage 13 goes through the connection, leading through the second automatic valve 14 to the passage 15 formed in one or two fingers 16, noped on the base of the vapia 5. On these fingers there are 16 cores; kitts are rotated cylindrical or the like part 17 with axis 1 1M passage 18, combined with passage 15. The cylindrical or the similar part 17 is designed as that she can t be

we derive from its regular worker a position in the worgpkalnaya, such as 11ok; Ano in FIG. 1-3.

The passage 18 is made in the form of a tube, which in its lower part is connected to the body 17, and in its upper part is provided with an outlet nozzle 19, the cone of which is 19%, the base of which is surrounded by a series of nozzles or holes 19.

The passage 18 in the cylindrical part is interrupted by a gap 20 that connects the annular channel 21, which in turn is connected by means of an inlet 22 to the second lip 16 to the tube 23. The other end of the tube 23 is connected through an iodine filter 24 and the metering pump 25 to the tube 30, to which the pulp composition is pressurized.

The exit sonlo 19 sinks the node of the surface of the conventional coagulum bath 26, and is partially surrounded by the funnel end 27 of the siphon tube 28, leading to an inlet 29, inside which a vacuum is maintained sufficient to suck fluid from the bath.

During operation, the cellulosic composition passes from tube 30 through pump 25, filter 24, tube 23 and feed 22 to annular channel 21 and into gap 20 leading to passage 18. Diaphragm pump 6 is empty from pipe 10 through valve 11 and passage 12 into chamber 9, from which liquid is pushed through passage 13 and through claian 14 into passage 15, from where it enters clearance 20 and subdivides the column of cellulose composition entering into passage 18 and flowing through tube 18 to nozzle 19, so that ejected in the form of short or measured fibers of appropriate length .

Short or measured fibers of any desired length are obtained in the manner described, by varying the amount of water injected with pump 6 into each 18 or each interval, or adjusting the speed of the pasos so that the frequency with which portions of water are subsequently pumped.

Any suitable liquid, except water, can be used to serve as a divider between the individual threads of the composition. If desired, the MOHjex separation medium is gaseous.

Fibers extending from several orifices of the nozzle 19 are held separately by the above cone 19i until the norm, they will not strengthen sufficiently in a coagulation solution to avoid combining them into one common thread.

After the individual fibers have been strengthened in the coagulation vapia, they are collected in the funnel-shaped end 27 of the siphon tube 28 and assembled along with the coagulation solution into the passageway 29, after which they can be separated from the excess coagulation fluid (which returns). into the bath) and collected as it is done with cotton fibers for the bristle yarn. The resulting fibers can be poured into any further processing, both in conjunction with cotton, and with other fibers.

The subject matter of the invention.

1. A method for producing artificial fibers of defined length, characterized in that the spinning solution coming out of the die is interrupted at certain intervals of time by spraying some liquid into it to break the strand yarn into individual fibers of a certain length.

2. An arrangement for carrying out the method according to claim 1, characterized by the application of a membrane pump 6 for injecting fluid from tube 10 through chamber 11, passage 12, chamber 9, passage 13, valve 14 and passage 15 into the gap 20, in order to subdivide solution on separate columns of a certain height (Fig. 1 and 2).
