The present invention is designed for denim by knitting Indego cotton yarn with excellent design through circular knitting machines, and exhibiting the fabric effect sufficiently while having the inherent elasticity, flexibility, breathability, and heat retention of the knit fabric. The present invention relates to a circular knitting machine for indigo denim fabric production and indigo denim fabric knitted through the same.

In general, indigo fabric refers to a fabric in which natural indigo dye is not dyed on cotton yarn and colored on the surface of the cotton yarn by a loop dying method. Therefore, the original index white of the cotton yarn is left inside the cotton yarn, after which the dyed indigo fabric undergoes the washing process, and the indigo-specific silhouette effect appears according to the part discolored and the degree thereof. Because of this silhouette effect, Indigo fabric has become one of the spotlight.

Therefore, many attempts have been made to manufacture fabrics for indigo denim to make jeans using the indigo fabric, but in the case of making denim fabrics with cotton weaving yarns of indigo yarns, a high density of twill ( Tewll) has a problem in that it is very difficult to apply to the jeans because the texture is not very rough and stiff as well as having a lot of wrinkles because it has a tissue.

In other words, the production of denim fabric is generally made through a cotton weaving machine which is divided into warp and weft yarns. This is because the tensile strength, which is generally recognized as a tough property, must be satisfied to some extent due to the characteristics of the jeans. However, if the indigo yarn is made through a cotton weaving machine as described above, there is no elasticity, so the fit is greatly reduced, which is not suitable for denim.

On the other hand, in order to compensate for these problems, indigo yarns and elastic yarns such as spanners were mixed to solve this elasticity problem to some extent, but in this case, it still does not retain the functions of ventilation, heat retention, etc. The problem still could not be solved.

In addition, the span yarn mixed with the indigo yarn in order to have a separate elasticity increases the manufacturing cost and manufacturing process of the fabric to significantly reduce the productivity.

In particular, when spanning yarn to indigo yarn is significantly different from other mixed fiber yarns including indigo yarn, the knitting process and post-treatment process are very demanding and not only high technology is required but also a difference in dyeability. do.

The present invention has been made in consideration of the above-mentioned conventional problems, and is indigo denim fabric manufacturing circular knitting machine that has all the flexibility, breathability, warmth, elasticity as well as elasticity without being mixed with elastic yarn having elasticity and manufactured using the same The purpose is to provide a fabric for indigo denim.

In order to achieve the above object, the present invention provides a knitting cam piece, a miss cam piece, and a chinking to perform the operations of knitting, miss, and tugging on the outer circumferential surface of a cylinder forming a track of a single needle. In the circular knitting machine in which the cam plate on which the cam pieces are installed is radially repeatedly installed, the cam plate comprises a first end cam consisting of an arrangement sequence of a miss cam piece, a knitting cam piece, a knitting cam piece and a miss cam piece, and an arrangement of a knitting cam piece, a miss cam piece, a knitting cam piece and a miss cam piece. And a third stage cam formed of a sequence of a second stage cam and a knitting cam piece-a knitting cam piece-a miss cam piece-a miss cam piece.

The present invention is a circular knitting machine in which a cam plate provided with a knitting cam piece and a miss cam piece and a tucking cam piece to perform weaving, passing and walking operations on an outer circumferential surface of a cylinder forming a track of a single needle is radially repeated. The first stage cam consists of the following sequence: Miss Cam: Knitting Cam, Knitting Cam, and Chink Cam. The second stage cam consists of the arrangement order of Knitting Cam, Miss Cam, Knitting, Miss, and Knitting Cam. -It comprises a third stage cam consisting of the arrangement order of the miss cam piece.

In this case, the knitting needle is a pair of the first short needle passing through the first end cam, the second short needle passing through the second end cam, and the third short needle passing through the third end cam, and the number of knitting needles per inch is 22 to It is set to 26 pieces (22 to 26 gauge).

And the subject innovation is in the fabric knitted through a circular knitting machine having a multi-stage cam made of a combination of at least any one of a knitting cam piece and a miss cam piece and a tucking cam piece, the fabric is 100 of 10 / S (20 / S + 2) thickness It is characterized by knitting indigo cotton yarn colored natural indigo dye on% white cotton yarn.

In this case, the fabric may be mixed and knitted into a rayon yarn of 10 / S (20 / S + 2) thickness on the indigo cotton yarn to have a weight of 7.5 oz / yd to 10 oz / yd and a thickness of 0.5 mm.

Alternatively, the fabric has a weight of 10oz / yd ~ 13oz / yd and a thickness of 0.9mm ~ 1.0mm knitting yarn mixed with 25 / S thick acrylic / wool (20% acrylic: 80% wool) blend in the indigo cotton yarn The acrylic / wool blend yarn may be formed in a protrusion shape on the inner side of the finished fabric.

The features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments based on the accompanying drawings. Prior to this, terms or words used in the present specification and claims are defined in the technical spirit of the present invention based on the principle that the inventor can appropriately define the concept of the term in order to best describe his or her own design. It must be interpreted to mean meanings and concepts.

1 and 2, the circular knitting machine for producing indigo denim fabric of the present invention is an annular cylinder (10) in which a plurality of knitting needles 40 are arranged in a vertical direction, and the outer wall surface of the cylinder (10) As a conventional single circular knitting machine having a cam plate 20 which is fixed repeatedly in a radial manner, a cam piece 30 forming a track of the knitting needle 40 is fixed inside the cam plate 20.

The cam piece 30 is the knitting cam piece 31 and the miss cam piece 32 and the chinking to perform the operations of knitting, miss, and tugging on the outer circumferential surface of the cylinder 10. Cam pieces 33, the path of the knitting needle 40 to move along the cam piece 30 in accordance with the arrangement state of the cam piece 30 is changed while the tissue of the knitted fabric is different.

Therefore, the arrangement state of the cam piece 30 is a very important factor that determines the nature and function of the fabric to be knitted.

In the cam plate 20 of the present invention, the cam pieces 30 are installed in three rows and four rows.

The cam plate 20 includes a first end cam A consisting of an arrangement sequence of a miss cam piece 31, a knitting cam piece 32, a knitting cam piece 32, and a miss cam piece 31, and a knitting cam piece 32 and a miss cam piece. (31)-Knitting cam piece (32)-Second cam (B) consisting of the arrangement order of the miss cam piece 31, Knitting cam piece (32)-Knitting cam piece (32)-Miss cam piece (31)-Miss cam piece (31) ) Is provided with a third end cam (C) consisting of an arrangement order.

The single needle 40 passes through the first and second end needles 41 and 41 passing through the first end cam A and the second end cam 42 passing through the second end cam B. The third fragment needle 43 is arranged in a series and vertically arranged in the cylinder 10 such that the number of knitting needles per inch is 22 to 26 (22 to 26 gauge).

When the indigo cotton yarn is knitted using the circular knitting machine for producing the indigo denim fabric having the configuration as described above, a fabric of the structure as shown in FIG. 3 is obtained.

That is, when the circular knitting machine operates, the first short needle needle 41 enters the first end cam A while the cylinder 10 rotates and passes along the miss cam piece 31 as it is. Entering the two-stage cam (B) to perform the weaving operation along the knitting cam piece 32, the third short needle 43 then enters the third stage cam (C) piece to perform the weaving motion along the knitting cam piece (32). do. The operation of the knitting needles 40 is made in a continuous and sequentially, as a result is to obtain a fabric for indigo denim having a knitting structure as shown in FIG.

When the indigo denim fabric has such a knitting structure, it has elasticity, flexibility, breathability, and thermal insulation, instead of lowering the density basically compared to the twill structure obtained through a cotton weaving machine. In particular, it has elasticity inherent to knitting without mixing separate stretch yarns.

At this time, the yarn fed into the circular knitting machine is suitable for indigo cotton yarns in which natural indigo dyes are colored in 100% white cotton yarns of 10 / S (20 / S + 2) thickness. This is because the finished fabric is too light when the thickness of the indigo cotton yarn is larger than 10 / S, and the fabric is too light when the thickness of the indigo cotton yarn is more than 10 / S, so it is not suitable for denim.

On the other hand, the circular knitting machine may be made by knitting two kinds of yarn. That is, in the circular knitting machine, two types of 100% white cotton yarn of 10 / S (20 / S + 2) thickness and an indigo cotton yarn colored with natural indigo dye, and 10 / S (20 / S + 2) rayon yarns of 10 / S (20 / S + 2) thickness are inputted. Can be. And the blended yarn is mixed and knitted to have a thickness of 0.5mm while having a weight of 7.5oz / yd ~ 10oz / yd of the finished fabric.

In this way, the thickness of the fabric is light and the rayon yarn changes sweat absorption according to the change of temperature, thus increasing the wearer's comfort, making it suitable as a summer denim fabric. Even if the fabric is manufactured through a cotton weaving machine using the yarns as described above, the fabric is rough and wrinkled by the twill weave, sweat is not absorbed and the ventilation is not made is not suitable as a summer denim fabric.

On the other hand, as shown in Figure 4, as another embodiment of the circular knitting machine of the present invention, the circular knitting machine cam plate 20 is a miss cam piece 31-knitting cam piece 32-knitting cam piece 32-tucking cam piece 33 The first end cam (D) consisting of the arrangement order of the second end cam (B) consisting of the arrangement order of the knitting cam piece (32)-miss cam piece (31)-knitting cam piece (32)-miss cam piece (31) The cam piece 32, the knitting cam piece 32, the miss cam piece 31, and the miss cam piece 31 may be constituted by a third end cam C.

In this case, two kinds of yarns are introduced into the circular knitting machine. That is, the yarn fed into the circular knitting machine is indigo cotton yarn colored natural indigo dye on 100% white cotton of 10 / S (20 / S + 2) thickness, acrylic / 25 / S (50 / S + 2) thickness Wool (20% acrylic: 80% wool) Two types of blended yarn. And the mixed yarn is mixed and knitted to have a thickness of 0.9mm ~ 1.0mm while having a weight of 10oz / yd ~ 13oz / yd.

When the yarn is put into the circular knitting machine having the cam piece arrangement structure as described above, the fabric is obtained, as shown in FIG. 5.

That is, when the circular knitting machine operates, the cylinder 10 rotates and the first short piece needle 41 enters the first end cam D and passes along the miss cam piece 31 as it is. Entering the two-stage cam (B) to perform the weaving operation along the knitting cam piece 32, the third short needle 43 then enters the third stage cam (C) piece to perform the weaving motion along the knitting cam piece (32). do. This is the same as the knitting operation described above, wherein the yarn being knitted is an indigo cotton yarn.

On the other hand, the first short needle (41) moves along the first end cam (D) and passes through the lasting tucking cam piece (33), the first short needle (41) passing through the tucking cam piece (33) The acrylic / wool yarn which is pre-feeded to the circular knitting machine, not to the indigo cotton yarn, will be walked over. As a result, the acrylic / wool yarn is left in the form of a projection (W) on the inside of the fabric.

The operation of these knitting needles 40 is made in a continuous and sequentially, as a result is to obtain a fabric for indigo denim having a knitting structure as shown in FIG.

Accordingly, the indigo denim fabric knitted has a lower density than the twill weave obtained through a cotton weaving machine, so it can have elasticity, flexibility, and breathability, and its unique stretchability is not required to be blended with a separate stretch yarn having elasticity. Will have

In particular, it is suitable as a winter denim fabric because the insulation is improved due to the acrylic / wool blend yarn left in the form of protrusions (W) in the form of a winter, and has a suitable weight and thickness as a winter denim fabric is excellent in fit.

According to the circular knitting machine for manufacturing indigo denim fabric according to the present invention configured as described above, by placing the cam pieces consisting of knitting cam pieces, miss cam pieces and tucking cam pieces in three stages and four rows, elasticity that is hard to find in fabrics produced through cotton weaving machines Indigo denim fabric can be used to make both the warmth and breathability of the indigo fabric.

In addition, even if not blended using a separate functional yarn, such as stretch yarn has the elasticity to the fabric itself has the effect of lowering the material cost and production cost of the fabric.

In addition, according to the indigo denim fabric according to the present invention, since it is manufactured through a circular knitting machine, it is excellent in elasticity, heat retention, and ventilation compared to the fabric of the twill tissue, and thus the fabric is light and soft because it does not need to be mixed with another elastic yarn such as spanner. It has no wrinkles and can make the silhouette effect peculiar to Indigo fabric, making it possible to produce jeans with excellent fit and fashion.

In addition, when blended with rayon yarn, the sweat absorption of the fabric is excellent, it is possible to produce a jeans suitable for the summer season.

In addition, when the acrylic / wool yarn is mixed, the fabric is ensured warmth has the effect of producing a suitable jeans for the winter.

Although the present invention has been illustrated and described in connection with specific embodiments, the present invention may be variously modified and changed without departing from the spirit or the scope of the present invention provided by the following Utility Model Registration Claims. It should be included in the scope of the present invention.
