Apparatus and method for manufacturing yarn for spliced wool with excellent elasticity

The present invention relates to an apparatus and method for manufacturing a yarn for ply-twisted wool fabric having excellent elasticity, and more particularly, to a stretchable yarn used for manufacturing a fabric including a spandex core.

Fabrics containing spandex yarns are woven using yarns of pure wool, polyester or wool blend wool and yarns of spandex yarns, and have excellent elasticity. It refers to the elastic fabric used. Conventionally, as a method of manufacturing a yarn for wool containing spandex yarn, a method of combining two strands of worsted yarn and one strand of spandex bare yarn and twisting them together is used.

However, when the yarn is manufactured by twisting in this way, since the yarn is formed in a spirally twisted form, the spandex core protrudes on the surface of the worsted yarn and is exposed on the surface of the wool during weaving, thereby damaging the quality of the wool. There is a problem in that uniform elasticity cannot be obtained after weaving and processing due to the difference in elasticity of spandex examination between cheese and cheese.

The present invention is made in view of the above problems, and an object thereof is to provide a silver yarn for wool having elasticity that is not exposed to the outside by spandex screening.

Another object of the present invention is to provide a woolen yarn containing spandex core having uniform elasticity and shape stability when manufacturing the fabric.

Another object of the present invention is to provide a manufacturing apparatus and a manufacturing method particularly suitable for manufacturing a yarn for stretchable wool.

In order to achieve the above object, the elastic yarn for wool of the present invention is a spandex core having a length of 0.4 to 0.6 times the length of the worsted yarn in the natural state with respect to the length of the worsted yarn with two strands of the same length as the length of the worsted yarn. The two strands of worsted yarn are ply-twisted in a form surrounding the outer periphery of the spandex core by stretching and placing them between the 2 strands of worsted yarn and braiding, and twisting the 3 strands arranged side by side. The method includes the steps of separating and withdrawing two strands of worsted yarn that are blown side by side from the braided cheese so as to open up in an inverted Y-shape, and supplying spandex cores in a stretched state between the two widened worsted yarns; The worsted yarn of the Samjiyan guide passes through the left and right side rings of the Samjiyan guide, and the spandex check passes through the central ring to determine the position, and the 3 strands of the yarn passing through the Samjiyan guide pass through the stopper guide in parallel. It consists of a step of drawing out in an organized form, and twisting and winding the three strands arranged side by side through a twisting device, and an apparatus for manufacturing the same is a braided yarn that draws out the two stranded yarns attached side by side. with cheese; Jigwan to withdraw spandex examination; a vertical feeder driven to limit the supply rate of the spandex screening to 0.4 to 0.6 of the worsted yarn supply rate; The spandex core passes through its central ring, and the two strands of worsted yarn drawn from the braided cheese are passed through each of its both side rings so as to be separated in an inverted Y-shape; a yarn guide for a stopper for passing the three strands of yarn that have passed through the Samji yarn guide in a form arranged side by side through a narrow slit hole thereof; While passing through the stopper yarn guide, it is configured to include a twisting device for twisting and winding three threads arranged side by side.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic diagram showing an embodiment of the present invention, wherein two parallel pieces of worsted yarn (1-1) (1-2) released from cheese (2) wound up by braiding two strands of worsted yarn (1) are reversed Y Separate the two strands in a Y-shape by allowing them to pass through both rings (4) and (5) of the samji yarn guide (3, 三枝 yarn guide) having three thread passage and support rings while separating them in a shape of a Y-shape so that the two strands are separated and continuously drawn out. The paper tube 8 is provided to rotate by the driving roller 7 between the braided cheese 2 and the Samjiyan guide 3, and when the paper tube 8 rotates, the spandex test wound on the paper tube 8 is (9) is drawn out, and the spandex core (9) released from the branch pipe (8) passes between a pair of transfer rollers (10, 11) and then passes through the central ring (6) of the Samjiyan guide (3). It is supplied between the worsted yarns (1-1) (1-2) passing through the both sides of the loops (4) (5) of the Samjiyan guide (3).

The three strands of yarn that have passed through the Samji yarn guide 3 are adjacent to each other while passing between the upper and lower discharge rollers 12 and 13 and pass through the inside of the stopper yarn guide 14 . The stopper yarn guide 14 has a narrow slit-type hole 15, and this hole is to the extent that 2 strands of worsted yarn and 1 strand of spandex can be blown through. The bobbin inserted into the spindle shaft of the extension device 16 by arranging the worsted yarns 1-1 and 1-2 on the left and right sides of (9) in a close contact form (three threads are gathered side by side and restrained) It is a means to be supplied to (17).

The rotating ring 18, which is a part of the twisting device 16, moves up and down along the spindle shaft 20 direction. At this time, the yarn is twisted while guiding the rotation with respect to the spindle rotation, and the twisted yarn is wound around the bobbin 17. .

When the traveler 19 rotates on the rotating ring rail while twisting the yarn and winding it on the bobbin 17, tension is applied to the yarn. 2) to be smoothly drawn out and supplied, and for the spandex screening (9), the withdrawal speed is drawn out at a rate of about 0.5 of the length of the worsted yarn (1) draw-out by a kind of break-in drive roller 7 and vertical feed rollers 10 and 11 limited as much as possible.

It is possible to control the rotation speed of the conveying roller 10 with a separate drive motor, but after the rotation shaft of the discharge roller 12 and the rotation shaft of the conveying roller 10 are meshed with a gear, the gear diameter ratio of both sides is adjusted. speed can be easily obtained.

That is, when the gear ratio of the feed roller 10 and the discharge roller 12 is set to 2 : 1 to form a gear train, the worsted yarn 1 by the tension generated when the traveler 19 rotates and is continuously fired on the bobbin 17 . ) from the braided cheese (2) is 1 m in length, the spandex core (9) can only be pulled out about 0.5 m from the paper tube (8). ) will be fired together.

In this way, in response to the rotational speed of the bobbin 17, the spandex core 9 is supplied at a length of 1:1 with the worsted yarn 1 and is not twisted, and is supplied at a length of about 0.5 times the supply length of the worsted yarn 1, , the reason for twisting and twisting after stretching by the difference in length between the two by tension is that when the spandex core 9 is stretched to a ply-twisted yarn in a loosely or taut state than that, it cannot have uniform elasticity and the elasticity is also significantly It is recommended to supply so that the ratio of the supply length of the worsted yarn (1) and the spandex core (9) is 1: 0.4 to 0.6, preferably 1: 0.5 in a natural state without stretching, and maintaining this ratio improves elasticity. is the determining factor.

The shape of the twisted yarn is a form in which the worsted yarn and the spandex core are spirally twisted together in the conventional case, but in the yarn according to the present invention, the worsted yarn located on both sides of the spandex core 9 located in the center maintaining a straight line ( 1-1)(1-2) takes a twisted form by winding the spandex core 9 in a spiral. This is completely different from simply winding the spandex core (9) in a straight line with the worsted yarn (1-1) (1-2) spirally wound around the periphery. A straight line is maintained because it is always constrained to be positioned at the center by the stopper yarn guide 14 .

Therefore, no matter where the twisted yarn is cross-sectioned at any position, the elastic yarn is manufactured so that the spandex core 9 is located in the center and the worsted yarns 1-1 and 1-2 are located on the left and right sides thereof. will lose

On the other hand, if the size of the worsted cheese is too large, the cutting phenomenon occurs. Therefore, it is preferable to set the size of pure woolen yarn 600g/cheese and blend yarn 800g/cheese size.

Table 1 below shows an example of the traveler usage standards according to the material and thickness of the worsted yarn and the thickness of the spandex core.

[Table 1]

Here, unexplained reference numerals 21 and 22 are stale wires and anti-varuning rings for guiding the braided threads.

According to the present invention, since spandex screening is made of worsted yarn and ply-twisted yarn with a constant draw ratio, it has excellent elasticity and shape stability in both the warp and weft direction and warp and warp direction when weaving a fabric using it. It does not protrude to the outside by the worsted yarn that is wound around the circumference in a spiral, so it does not impair the dignity when manufacturing clothes, etc.
