Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circular knitting machine for producing circular knitted fabrics having unevenness and a circular knitted fabric produced by the method.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circular knitting machine for manufacturing a circular knitted fabric having unevenness, and more particularly, to a circular knitting machine for manufacturing circular knitted fabric having unevenness for realizing a single yarn unevenness at the time of manufacturing circular knitted fabric.

A way to express the sense of volume on a fabric is to weave the fabric so that it has a sense of volume when weaving it.

[0002] Conventional fabrics have been made by fabricating woven fabrics made of plain weave with resin to form irregularities, or to place stretch yarns in a part of the fabrics.

However, such a fabric sheet has a drawback that the concave and convex state is weak and the expected effect can not be obtained.

In order to solve such a problem, a stretch yarn (spandex yarn) is inserted at regular intervals in the direction of inclination of the fabric, and the fabric is woven and shrunk to inflate the superstructure housing part to form the uneven fabric, Has been disclosed in Korean Registered Utility Model No. 20-0204671 (design name: uneven fabric), which is a soft and elastic fabric.

However, since the irregular fabric is a flat fabric, it is used in combination with polyester fiber and spandex yarn, so it is difficult to apply it to circular knitted fabric. Since the unevenness of polyester fiber is formed by swelling of the polyester fiber due to the expansion and contraction of spandex yarn, It is difficult to implement in reality.

Therefore, it is urgently required to develop a circular knitting machine which can be applied to a circular knitted fabric and which can realize unevenness of a single yarn.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a circular knitting machine for manufacturing a circular knitted fabric having unevenness for realizing one kind of yarn unevenness in manufacturing a circular knitted fabric.

A circular knitting machine for manufacturing a circular knitted fabric having unevenness according to the present invention is a circular knitting machine for producing a circular knitted fabric by up-down movement and back-and-forth movement of a circular knitting needle by a cylinder cam for vertically moving a circular knitting needle and a dial cam for moving back and forth, (100) are formed in two rows, and the arrangement state becomes a state of an uphill knit (110) - a miss (120) - a miss (120) Miss 120 and the downward movement becomes a knit 110 -MIS 120 -MIS 120, the ascending is a miss 120 -MIS 120 - The cylinder cams 200 are formed in two rows and the upward movement is performed in the order of the knit 210, the miss 220, and the miss 220, Knit 210 and knit 210 are repeated six times, and the downward direction is a state in which the miss 220, the knit 210, and the knit 210 are repeated six times, (210) - Miss (220) - Scan the form to be repeated 220 times to 6 it characterized in that the dog is a set 36.

The number of circular needles operated by the respective cylinder cams 200 is three to twelve.

Further, the yarn to be woven is characterized by being a nylon DTY yarn.

The yarn to be woven is characterized by being a synthetic yarn of nylon DTY yarn and spandex yarn.

At this time, the synthetic yarns of nylon DTY and spandex yarn are characterized by 91 to 97% by weight of DTY and 3 to 9% by weight of span.

The present invention is applicable to the production of circular knitted fabrics. Unlike the conventional method of embossing two yarns, it is possible to fabricate one type yarn unevenness, thereby making it possible to manufacture a fabric having a beautiful appearance, It is possible to obtain a fabric having excellent unevenness and excellent appearance, and having a unique sense of aesthetics and excellent ventilation and feel of the fabric.

Moreover, since it can be realized as one kind of yarn, the manufacturing is simple and the productivity can be improved.

In addition, in the case of embodying a yarn having elasticity, even if it is stretched or shrunk, the shape of the concavo-convex shape can be maintained without changing.

FIGS. 1 and 2 are views showing a dial cam of a circular knitting machine for manufacturing circular knitted fabrics having irregularities according to the present invention, and FIGS. 3 and 4 are views showing a cylinder cam of a circular knitting machine for manufacturing circular knitted fabrics having irregularities according to the present invention FIG. 5 is a diagram showing the organization of a circular knitting machine for manufacturing circular knitted fabrics having irregularities according to the present invention, and FIG. 6 is a photograph showing a circular knitted fabric manufactured by circular knitting machines for producing circular knitted fabrics having unevenness according to the present invention.

A circular knitting machine for manufacturing a circular knitted fabric having unevenness according to the present invention comprises a diaer cam and a cylinder cam.

The dial cam 100 serves to move the circular knitting needle back and forth. The dial cam 100 serves to form concavities and convexities in the same direction as the weaving direction of the woven fabric of the knitting machine, that is, the circumferential direction of the fabric to be woven by moving the circular knitting needle back and forth.

The cylinder cam 200 serves to move the circular knitting needle up and down. The cylinder cam 200 serves to form concavities and convexities in the same direction as the longitudinal direction of the fabric to be woven in the circular knitting machine by moving the circular knitting needle up and down.

Figs. 1 and 2 show the arrangement states of the dial cams, and Figs. 3 and 4 show the arrangement states of the cylinder cams.

The dial cam 100 is formed in two rows, and the upward and downward directions are alternately arranged so that the number of the dial cams is one. As shown in FIG. 1, when the uphill is in the form of a knit 110, a miss 120, and a miss 120, a downward run may be miss 120, miss 120, As shown in FIG. 2, when the downward movement is in the form of a knit 110, a miss 120, and a miss 120, the upward movement is miss 120, (120).

The cylinder cam 200 is formed in two rows and the upward movement is repeated six times for the knitting 210 to the miss 220 and the miss 220 to the knitting 210 to the knitting 210 The knee 210 is repeated 6 times and the knee 210 is repeated 6 times while the knit 220 is repeated 6 times. And 36 pieces become a set.

Fig. 5 shows an organization chart according to the arrangement of the dial cam and the cylinder cam.

In Fig. 5, the dial cams denote A and B, where A is up and B is down. Also, the cylinder cam represents 1 and 2, 1 represents up, and 2 represents down.

The upward movement of the dial cam is changed to the knit 110-the miss 120-the miss 120 and the upward movement of the cylinder cam-the first knit 210 -the miss 220- The yarn is weaved in the knit 110 section of the upward movement A of the dial cam and the knit 210 of the upward movement of the cylinder cam to woven the circular knitted fabric. Since the yarn is not woven in the region of the miss 220 of the upward movement of the cylinder cam, the circular knitted fabric remains swollen and is woven.

When the downward movement of the cylinder cam 2 becomes the miss 220, the knit 210, and the knit 210, the gap between the miss 120 of the upward movement of the dial cam and the knit 210 of the downward movement of the cylinder cam, This weave knitted fabric is knitted. The yarn is not woven in the second miss 220, which is the downstream of the cylinder cam, so that the circular knitted fabric keeps the swollen state and is woven.

Repeated three times in this form, one woven or woven fabric is woven.

On the contrary, when the upward movement of the dial cam A is changed into a knit 110, a miss 120, and a miss 120, the two-way knitting 210, the miss 220, 220, the yarn is weaved in the knit 110 section of the upward direction A of the dial cam and the knit 210 of the downstream direction of the cylinder cam so that the circular knitted fabric is woven. The yarn is not woven in the second miss section 220, which is the downstream of the cylinder cam, so that the circular knitted fabric remains in a swollen state on the opposite side and is woven.

When the cylinder cam 2 is a knit 210 - a miss 220 - a miss 220, a section of the miss 120 of the upward A of the dial cam and a knit 210 of the downstream of the cylinder cam 210 This weave knitted fabric is knitted. The yarn is not woven in the second miss section 220, which is the downstream of the cylinder cam, so that the circular knitted fabric remains in a swollen state on the opposite side and is woven.

Repeating three times in this fashion results in the woven fabric being woven into one embossed or convex type fabric and the other adjacent convex or concave type fabric.

If the already woven fabric is tucked in, the adjacent woven fabric will become a convex portion.

Fig. 6 shows a photograph of a circular knitted fabric woven in the form of concavities and convexities.

And the recessed portion 300 of the fabric and the convex portion 400 are alternately woven together.

At this time, it is preferable that the number of needles operated by each cylinder cam 200 is three to twelve.

If the number of needles is too small, the irregularities of the fabric to be woven become uneven and the boundaries of the irregularities become vague, so that the effect of irregularities can not be exhibited. When the number of needles is too large, It is desirable to maintain an appropriate number of the needles operated by the respective cylinder cams.

At this time, the yarn to be woven is preferably a nylon DTY (Draw Textured Yarn) yarn.

The yarn to be woven may be made of a single yarn twist giving a twist to a single yarn or a twist twist giving a twist to a double yarn twist.

When the yarn is made into a core yarn in a single yarn twist, it is preferably in the same direction (Z twist) as the twist direction of the nylon DTY. In the case of a single yarn twist, a restoring force may be generated in which the twisted yarn is going to return to its original state. Therefore, when the twist direction of the yarn is twisted in the same direction (Z twist) as that of the nylon DTY, the restoring force is reduced.

It is also preferable that the yarn to be woven is a synthetic yarn of nylon DTY yarn and spandex yarn.

When the yarn to be woven becomes a synthetic yarn of nylon DTY yarn and spandex yarn, the yarn becomes more stretchy than the fabric made of nylon DTY yarn.

At this time, it is preferable that the ratio of nylon DTY yarn to synthetic yarn of spandex yarn is 91 to 97% by weight of nylon DTY yarn and 3 to 9% by weight of spandex yarn.

If the ratio of the spandex yarn is too small, the shape of the concave / convex portion can be maintained, but the stretching shrinkage becomes small. If the ratio of the spandex yarn is excessively large, the elongation is large but it is difficult to maintain the shape of the concavo-convex portion.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
