Description

[0001] The present invention relates to a device for manufacturing fabrics including spandex,

The present invention relates to a knitting machine having a spandex material knitted by a knitting method, and more particularly, to a knitting machine having a spandex yarn and a bottom yarn including a spandex material, Thereby improving the quality and maintaining the span extension force.

The knitting machine is a kind of textile machine which produces nose by making the nose by the movement of the knitting yarn using the yarn supplied to the knitting needle, and softening the nose in the lateral and longitudinal directions to produce the knitted fabric (fabric).

The above-described knitting machine is divided into warp knitting machines for knitting warp yarns in the longitudinal direction and warp knitting machines for knitting the weft yarns in the lateral direction. The knitting machines belong to the category of the weft knitting machines. The knitting needles are arranged in a circle on the cylinders, The knitting yarn is fed to the knitting needle to continuously produce the knitted fabric, and the knitted fabric is finished through the cutting process. Such a knitted fabric production apparatus is basically fed to the knitting needle, and the span yarn has a lot of new shrinkage, so that the yarn is slackened by the tension when the yarn is fed.

Fabrics including spandex yarns of spandex are highly wearable due to their high elasticity and restoring force, and have recently been used as fabrics for a variety of garments such as functional garments. In the case of span yarn, the quality of the fabric, that is, the restoring force of the fabric, is determined by the content of the span. In order to increase the quality of the span yarn, the thickness of the span yarn is increased by raising the content of the span yarn. Height method has been used. This is because, in the case of a conventional fabric manufacturing apparatus, a single yarn is discharged from the bottom yarn and the span yarn in the span yarn in the span yarn.

However, when the thickness of the span yarn is increased, the restoring force of the span increases greatly, but the span stretching force decreases inversely. In case of spun fabrics, the restoring force is also important. However, since the fabric is stretched smoothly when stretched, the decrease in elongation of the fabric has been pointed out as a problem in that the production of spun fabrics is less competitive.

On the other hand, among the circular knitting machines, double cylinder circular knitting machines are widely used. The double cylinder circular knitting machine is made by the forward and backward movements of the upper needle positioned in the dial portion and the up and down movements of the lower needle located in the cylinder portion. In the case of a double cylinder type circular knitting machine, a pattern (pattern) is formed by changing the number of needles when the yarn is fed to the knitting needle. In the case of a circular knitting machine using a single span yarn feeding method, It is impossible to apply span yarn to each yarn by applying different tension to each yarn because of the limitation, and thus it is pointed out that the span yarn can not be put on the entire knitting yarn, so that the pattern and kind of the weaving yarn are very limited .

The present invention has been devised in order to solve the above-mentioned problems, and it is an object of the present invention to provide a spandex fabric comprising a spand yarn made of spandex material, The goal is to provide a technique for fabricating fabrics that can be manufactured.

On the other hand, by solving the limitations of the single span yarn yarn yarn, it is possible to provide yarns of different span types at different tensions and velocities for each knitting yarn even if the number of needles are different, The goal is to provide a technology that can be produced.

In order to attain the above object, according to an embodiment of the present invention, there is provided a spandex fabric manufacturing apparatus comprising spandex, spandex yarn made of spandex, and spandex fabricated by knitting a bottom yarn made of spandex, A plurality of yarns are supplied to the knitting needle so that a nose is generated in accordance with the reciprocating motion of the knitting needle, and the generated nose is knitted, An annular part for generating a tail of the set pattern; At least one bottom yarn feeder including a plurality of bottom yarn feeders arranged in a circle for feeding bottom yarns and at least two bottom yarn feeders including a plurality of circularly arranged span yarn feeders for feeding span yarns A span yarn yarn feeding portion for yarn feeding the yarn from the yarn feeding means to each yarn of the circular knitting machine so that at least one bottom yarn and at least two span yarns are fed from the yarn feeding means, A sudden death part; And a yarn feeding control unit for controlling a yarn feeding speed of the yarn fed from the bottom yarn feeder and the span yarn feeder to control the yarn feeding tension of the yarn.

According to the present invention described above, a span yarn feeder is configured to feed a plurality of spun yarns having a low denier (thickness) to a knitting needle at the same time, and a fabric is produced while simultaneously feeding a bottom yarn and a plurality of thin spun yarns to the knitting needle .

In this case, since the span yarn can be kept thin and the span content can be increased, and the stretching force for restoring the spandex can be increased and the spandex yarn can be stretched smoothly, the fabric including the spandex material having excellent quality can be manufactured It is effective.

Meanwhile, when a plurality of span yarns are included at the same time, even when a span yarn is partially cut at the time of fabrication, dyeing, and processing, the other span yarns are kept at the same time while the span content is high, Or the phenomenon of the increase is minimized.

On the other hand, as the tension of the spun yarn fed to the knitting needle and the yarn feeding speed are variously adjusted as the tension of each span yarn feeding portion is adjusted differently, the number of the knitting needles The spun yarn can be put on the entire knitting needle together. Therefore, according to the single cylinder circular knitting machine, the double cylinder circular knitting machine, and the jacquard fabric manufacturing apparatus, it is possible to produce a new fabric (kind and pattern) close to almost infinite.

As shown in FIGS. 1 and 2, the span yarn feeders 41 and 51 are connected to both sides of the center of the two cylindrical span yarn windings, The rotational force is changed so that the two cylinders are moved in opposite directions to each other so that the spun yarn is fed to the knitting needle.

Specifically, the two cylinders are coupled at different angles to the central axis of the drive plate of the span yarn feeder 41, 51, preferably the drive plate, so that the two cylinders are circularly circular The spun yarn is released from the winding and is fed to the knitting needle.

The first gear portion and the second gear portion may be detachably installed on the motor portion and the drive shafts 61 and 62 so as to have different gear ratios, respectively. For example, the first gear portion and the second gear portion are set in advance and are supplied while the gear box 60 is commercialized.

By replacing the use of coarse spun yarns with the use of a number of thin spun yarns as described above, spun yarns of 20 to 30 denier in thickness are conventionally used without the use of spun yarns of about 40 denier This experiment proved that it can be used.

The length of the span yarn can be set so as to increase from about 2.8 to 3.5 times during the sudden yarn feeding. In this case, when the yarn number of the bottom yarn is 30, 5.3cm. If the span yarn is shorter than the span yarn, the span is broken during the weaving operation, and the weaving operation is impossible. Even if the span yarn is too long, the weaving can not be performed.
