The present invention relates to a method for producing a compound paralledled raw silk in which a cocoon thread is connected around a core thread made of a yarn other than the cocoon thread.

機)의 회전접서기(回轉接緖器) 아래에 코어실용 실공급관을 설치하고, 코어실로부터의 인출코어실을 회전접서기에 삽통하고, 코어실을 중심으로 그 주위에 누에고치에서 뽑아낸 고치실을 엉킨 상태로 끌어낸 다음, 켄넬시스템(Kennel system)을 거쳐서 섬도(纖度)를 감지하고, 유제(油制)를 부여하는 오일링(oiling)을 실시하여 작은 리일(reel)에 감는, 복합포합법(Compound cohesion method)이라 불리우는 조사 방법이 있었다.Conventional Automatic Irradiator

Install a thread supply pipe for the core thread under the rotary folding machine of the machine, insert the core thread from the core thread into the rotating folding machine, and pull the cocoon around the core thread from the cocoon around it. After pulling out the cocoon thread, the fineness is sensed through the Kennel system, and the oiling is applied to the small rail to give an emulsion. There was an investigation method called the compound cohesion method.

In the form of the composite composite yarn 50 according to this method, the cocoon chamber 52 should completely cover the core chamber 51. However, in the case where the core chamber 51 is other than the cocoon chamber, the cocoon chambers 52 are actually sericin ( sericin), and only a part of the cocoon thread is joined to the core thread 51 by sericin.

Therefore, the cocoon chamber 51 and the core chamber 52 are easily separated, and the cocoon chambers are not joined to each other over a long section.

Therefore, in particular, during re-reeling, the peeling phenomenon such as the circular section is often generated.

A hybrid entanglement method has been developed in which a cocoon thread is entangled around a core chamber made of a yarn other than the cocoon chamber by an air jet nozzle installed above the thread guide tube.

The composite articulator 60 thus made is subjected to a fineness sensor through a kennel system, oiled with an emulsion, and wound on a small thread.

Since the entanglement of the cocoon thread 62 with respect to the core thread 61 is good for the composite entangled yarn 60 irradiated by the compound entanglement method, the yarn 62 is wound around the core thread extension, so that the stretchability Knitting paper using the yarn is excellent in elasticity and fatigue resistance.

On the other hand, however, the cocoon chamber 62 and the other fibers 61 are easy to separate, particularly when dried on a reel and then re-reeling, to be easily separated due to the difference in heat shrinkage between the two. Glasses-shaped round nodes are generated and separation of the cocoon chamber 62 and the core chamber 61 is likely to occur, and the smoothness is inferior.

In view of the above, the present invention provides a composite-layered yarn in which separation does not occur between the fibers of the core yarn other than the cocoon chamber and the cocoon thread wound around it, and no circular shape of the spectacles is generated. The purpose is to get.

In the irradiation method in which a cocoon thread is connected around a core chamber made of a thread other than the cocoon chamber, and wound around a kennel system, the coil is wound at a high speed of 330 m / min or more to give a irradiation tension of 17 g / 20 d or more. By spraying hot air at 50 ℃ or higher around the rail to promote dry drying, the focusing of the cocoon and core threads was increased to improve the paralleling quality.

EMBODIMENT OF THE INVENTION Hereinafter, the irradiation method of this invention is demonstrated next with drawing of the apparatus which performs this method.

In the illustrated device, a folding machine 2, a first pulley 4 for constructing a kernel system, a fineness sensor 5, and a second upper part of a reeling-off section 1 are provided. The swing arm (8) having the third pulley (7) at the tip of the pulley (6), the interlocking member (9), the oil ring roller (10), and the upper rail (11) are installed, and the periphery of the rail (11) The drying pipe 12 and the fan 13 are installed in the air, and hot air is blown onto the rail by the rotation of the fan 13 to dry the raw sand wound on the rail 11.

A cover 14 is provided around the drying pipe 12.

The rocking arm 8 lifts the tip of the rocking arm 8 when an abnormality occurs in the thread and the tension of the thread is increased, and the rotation of the rail 11 is stopped by a mechanism (not shown). By lengthening and materially lightening, it is possible to stop the rail 11 immediately by the tension of the yarn which is generated momentarily, thereby preventing the cutting of live sand.

The cocoon feeder 15 circulates on the front face of the yarn disassembly unit 1 and folds the folding machine 2.

The core thread 16 made of fibers other than the cocoon thread is wound from the lower part of the folding machine 2 by the thread guide tube 19 in the state wound around the cheese winding machine 17 on the frame 18. Is guided to the center of the

The boiled cocoons 21 hanging on the cocoon feeder 15 are folded into the folding machine 2 and introduced into the thread decomposing unit 1, so that an appropriate amount, preferably 4 to 5, is raised.

On the other hand, the core thread 16 made of fibers other than the cocoon or the cocoon thread wound on the cheese winding machine 17 is the central position of the cocoon 20 from the lower part of the folding machine 2 through the thread guide tube 19. It enters and is sent out together with the cocoon chamber 22, and the cocoon chamber 22 adheres and covers around the core chamber 16, and is wound up at a high speed of 330 m / min or more with a composite yarn of 20d.

At this time, the irradiation tension is 17g / 20d or more.

In the case where the cocoon feeder 15 is folded to the folding machine 2 for the high-speed irradiation, the interval from the next folding to the next folding is shortened to about 2.0 seconds to prevent the occurrence of seal stains.

The yarn wound on the rail is dried by blowing hot air of 50 ° C. or more by the drying pipe 12 and the fan 13 provided on the upper, side, and bottom of the rail.

The hot air spouted at the rail is 50 ° C or higher because the irradiation speed is high. If the temperature is lower than this temperature, the yarn wound on the rail to be raised cannot be sufficiently dried.

In the method of the present invention, as described above, the yarn 25 irradiated because of being raised at a high speed is increased in tension during irradiation and is in a state of 17 g / 20 d or more of irradiation tension, so that the cocoon yarns and the cocoon yarn and the core yarn are firmly secured. Overlapping is included and it becomes a straight form.

Therefore, separation of the cocoon thread and the core thread does not occur easily, and the occurrence of loops such as eyeglass-shaped circular knots is suppressed, and adjacent cocoon threads are connected to each other in a state where they overlap each other, and as shown in FIG. The joining by (sericin) is performed sufficiently, and the part 26 which becomes a shape by the joining is twisted and joined with the core thread 16 in the state containing the filament yarn 27 which comprises the core thread 16. do.

In the present invention, since the yarn under irradiation is wound at a high speed of 330 m / min or more, the irradiation tension is increased, but no knot is generated, and the yarn is smooth.

The occurrence conditions of large, medium and small nodes according to the irradiation speed during the irradiation are shown in the first table and the second table.

Tables 1 and 2 above show the results of the biopsy test, and the test method will be described more specifically as follows.

(1) large node inspection

This test examines the types and masses of mass nodes present in life and death.

As a lighting device for node inspection, the number of large and large nodes in each panel (127mm in width and 457mm in width) is examined by inspection on both sides of the inspection panel by comparing the number of large and medium nodes to the standard picture of the large and medium nodes.

The result is 1 point for oversized node and 1 point for large node for 0.4 point, and 0.1 point for node for total node. The total score of 100 panels is subtracted from 100 points.

Here, each node type and its definition are as follows.

① super major defects

At least ten times the minimum length or size of each species of stem

② intertwined (waste)

Having lumps of cocoon or green thread in thread

③ large slugs

The length of the part where the thread is remarkably thickened is 7 mm or more

④ bad cast

The thread suddenly thickening due to thread breaking or connection

⑤ very long knot

The length of the cut end of the thread being more than 10 mm or shorter than that.

⑥ heavy corkscrew

Significantly large shape of spiral section of cocoon chamber

(2) small node test

This test examines the degree of somite present in life and death.

With the same lighting system as large and medium node inspection, the small, size and distribution of small nodes in each panel are examined and scored by 100 point method in comparison with the standard image of small node.

인 열등파넬의 평균점으로 표시한다.Results are averaged at 100 panels and 100 panels

It is expressed as the average point of the inferior panel.

Here, each node type and its definition are as follows.

① small sag body (smallslug)

The length of the part where the thread becomes remarkably thick is 2 mm or more, less than 7 mm, or a part of the thread is bulky.

② long knot

With a length of cut end of the thread of not less than 3 mm and less than 10 mm

③ corkscrew

Spiral part of cocoon thread is slightly larger.

④ big ring, cleavage node

The part of cocoon which comprises a thread is separated from a thread, and the length of the part which becomes annular (or branched) is 10 mm or more.

The inspection of the joint portion as described above is made by using a ceriprene winding device that is to rotate the inspection plate, wound the raw sand of a certain length to a certain interval.

According to Tables 1 and 2, it is evident that the occurrence of the above defects can be minimized when irradiated at a high speed of 330 m / min or more.

[Table 2]

Small node test (total number of appearances of sericoprene and 100 panels)

According to the method of the present invention, in the irradiation method in which a cocoon chamber is connected around a core chamber made of a yarn other than the cocoon chamber, and wound around a rail via a kennel system, the irradiation tension of 17 g / 20 d or more is reduced by winding at a high speed of 330 m / min or more. In addition, since the overlapping property was improved by blowing hot air of 50 ° C. or higher around the rail, the cocoon threads, the cocoon thread, and the core thread were firmly included, so that the overlapability was good, and the straight form was obtained.

As a result, separation of the cocoon thread and the core thread does not occur well, and the round shape of the spectacles is eliminated, and a smooth thread can be obtained.
