Description

Method for manufacturing tricot fabric with self-supporting loops

One aspect of the present invention relates to a method of manufacturing a tricot fabric having a self-supporting loop, and more particularly, a tricot fabric formed so that the loop is independent through the in-out diameter of the yarn on a tricot knitting machine, and a tricot fabric for manufacturing the same It relates to a method of manufacturing the fabric.

The content described in this section merely provides background information on the embodiments of the present invention and does not constitute the prior art.

Fabrics can be broadly divided into woven and knit (warp knitting, weft knitting). Among knits, warp knitting refers to a fabric that connects loops (nose, stitches) and loops in the warp direction, that is, in the longitudinal direction. direction, that is, in the horizontal direction.

A tricot is a kind of warp knitting, meaning that two or more guide bars are coordinated when knitting. The general knitting method is to knit only with warp beams. That is, the tricot fabric is woven through a thread on the branch of each guide in the longitudinal direction.

As the guide bar moves left and right in the tricot fabric, when viewed from the back of the fabric, a zigzag horizontal line is created. Also, the surface of the fabric looks like a plain stitch with a trough in the longitudinal direction.

Tricoat is a thin fabric with good shape stability. Because the yarn is woven in the form of a knot, the nose of the yarn does not come off easily, and it usually has some elasticity in the horizontal direction. It has the advantage that it does not look good and the edges do not come loose. These tricot fabrics range from heavy to light and are generally used for multiple applications, such as underwear, pajamas, housewear, linings, dresses, and upholstery.

On the other hand, it is common to perform a raising process to form a loop or to form a raising on the fabric. The raising process is a process of scraping the surface of the fabric at a constant rotational speed with a needle like a hook of a raising machine after making the fabric. For example, rubbing the skin with sandpaper is a similar principle to the rise of flesh, and this is called raising.

In the textile field, the raising process is a processing method to generally scrape or pull the fibers constituting the fabric to make the surface of the fabric fluff, to soften the texture of the fabric, to make the fabric look thicker, and to sometimes increase the warmth.

As a raising method, in the past, there was the teazel raising method, in which the surface of the fabric was scraped several times using pine needles or needles to make it fluff, or dried thistle seeds were used to raise the thorns. It is often used for raising soft fabrics such as blankets, flannel, or high-quality woolen fabrics or coated papers. The tea gel used here is a kind of thistle, which is now specially grown for raising, and there is also an artificial tea gel made of synthetic resin.

This tea gel raising machine attaches a lot of tea gel to the surface of a large drum and causes fluff by rotating it at high speed while in contact with the fabric. In general, a chimbo raising machine is used for raising low-grade wool fabrics, cotton wool fabrics, cotton flannel fabrics, and chemical fiber fabrics. In this machine, a chimney with needles bent in a certain direction is wound around a drum, and hair is raised while rotating it.

A general tricot fabric must be subjected to a raising process using the above-mentioned raising machine in order to raise the loop. In other words, since the tricot fabric is woven at an oblique angle, the shape is formed from left to right. The yarn that makes up the floor is not an in-out method, but a method in which all yarns are passed through a guide and weaved with a needle, so it is a loop that can make raising Both ends of the fabric are woven into the bottom yarn and attached to the bottom of the fabric. Therefore, there is no choice but to set up the loop through a raising process that takes out the loop separately.

However, if the loop is erected through the raising process, the loop is cut or the height of the loop is formed at different times during the raising process, resulting in a high loop defect rate and increasing the number of manufacturing steps for the fabric, which increases the manufacturing time and manufacturing cost. become a problem

In addition, in general, brushed velcro paper uses NYLON material with good yarn strength and elongation to lower the cut rate of loops during raising, which is more expensive than other chemical fibers (POLYESTER) and is highly affected by temperature and humidity. .

Therefore, research to simplify the process, reduce the defect rate of loops, and have price competitiveness is urgently needed.

One of the plurality of third loops 310 of the third yarn 300 may share a root with one of the first loop string 400 or the second loop string 410 , and The other one of the plurality of third loops 310 may be formed in the under-loop column 500 instead of the first loop column 400 and the second loop column 410 .

That is, the first loop array 400 according to the present embodiment may be formed by sequentially weaving the first loop 110 and the second loop 210 , and the second loop array 410 is the first loop array ( Contrary to 400), the second loop 210 and the first loop 110 may be sequentially interwoven.

In the first yarn 100 , a plurality of first loops 110 may be intersected in a zigzag manner (see FIG. 2 ), and in the second yarn 200 , a plurality of second loops 210 may be formed as a first yarn. Contrary to (100), it may be cross-formed in a zig-zag (see FIG. 3 ).

Here, the meaning that the first yarn 100 intersects the first loop 110 in a zig-zag manner means that, referring to FIG. 2 , one of the plurality of first loops 110 of the first yarn 100 has a first stroke. A first loop row 400 is formed in (a), a second loop row 410 is formed in a second process (b), and a first loop row 400 is formed again in a third process (c). and forming the second loop column 410 again in the fourth stroke.

In addition, referring to FIG. 3 , the second yarn 200 crosses the second loop 210 in a zig-zag manner according to the embodiment, among the plurality of second loops 210 of the second yarn 200 . One forms the second loop string 410 in the first stroke (a), the first loop string 400 in the second stroke (b), and the second loop string again in the third stroke (c) Forming 410 may mean forming the first loop column 400 again in the fourth stroke.

Specifically, referring to FIG. 2 , the first yarn 100 forms the first first loop 110 while returning to position number 2 -> 3 in the first stroke (a), and in the second stroke (b) A method of forming the second first loop 110 while returning to position number 1 -> 0, and forming the third first loop 110 while returning to position number 2 -> 3 again in the third stroke (c) to form a first yarn loop row.

Referring to FIG. 4 , the first yarn 100 and the second yarn 200 form a first loop string 400 and a second loop string 410 while forming zigzag loops opposite to each other as the stroke progresses. can do.

In the present specification, the first loop column 400 means a loop column in which the first loop 110 and the second loop 210 are alternately formed and extended in the vertical direction, and the second loop column 410 is also vertical. The second loop 210 and the first loop 110 are alternately formed in the direction and may refer to a loop column extending.

According to the embodiment, the first loop row 400 and the second loop row 410 have a position number assigned therebetween, but at a predetermined interval along the horizontal direction with the underloop row 500 having no loop formed therebetween. It may be formed to be spaced apart. Here, the under-loop row 500 means an empty loop row in which no loop is formed between the first loop row 400 and the second loop row 410, where the bottom yarns constituting the bottom structure of the fabric are crossed. connected in the form. In this specification, these floor yarns are expressed as under-loop.

That is, when the first yarn 100 forms the first loop 110 in the first stroke (a) and forms the second first loop 110 in the second stroke (b), the first loop 110 And the portion formed by the yarn connecting the first loop 110,

When the second yarn 200 forms the second loop 210 in the first stroke (a) and the second second loop 210 in the second stroke (b), the second loop 210 and the second second loop 210 are formed. The bottom structure formed by the portion formed by the yarn connecting the two loops 210 is called an underloop, and when this underloop is formed at a position where a position number is assigned, this is expressed as an underloop row 500 .

In the first loop row 400 and the second loop row 410, loops (the first loop 110 and the second loop 210) are woven with each other, but in the under loop row 500, no loops are woven. .

Referring to FIG. 5 , the third yarn 300 may also form a plurality of third loops 310 while a stroke is performed like the first yarn 100 and the second yarn 200 . Here, one of the plurality of third loops 310 of the third yarn 300 may share a root with one of the first loop string 400 or the second loop string 410 . That is, the first loop 110 or the second loop 210 constituting the first loop array 400 may be intertwined and fixed, but the other one of the plurality of third loops 310 is the first loop array 400 . However, since it is formed in the under-loop column 500 instead of the second loop column 410, there is no adjacent loop capable of fixing the loop up and down (meaning the vertical direction), so it is not fixed. As a result, the third loop 310 formed in the under-loop column 500 becomes self-supporting. Here, the expression that the loop is self-supporting means that the loop that is not fixed becomes a free end and stands up.

Specifically, referring to FIG. 5 , the third yarn 300 forms the first third loop 310 while returning to position number 1 -> 0 in the first stroke (a), and in the second stroke (b) The second third loop 310 is formed while returning to position number 3 -> 4, and the third third loop 310 is formed while returning to position number 1 -> 0 in the third stroke (c) again. Three yarns form a loop row, wherein the second third loop 310 is a self-supporting loop because it does not share a root because it is formed in an underloop row 500 with a position but no loops. For reference, in this specification, the under-loop row 500 means a row without loops formed by the yarns constituting the fabric base (that is, the first yarn 100 and the second yarn 200 in this embodiment). . Accordingly, a loop of yarn (the third yarn in this embodiment) that becomes a self-supporting loop in the underloop row may be formed.

Sharing a root here means that loops and loops are intertwined. Referring to FIG. 6 , according to the embodiment, the third loop 310 of the third yarn 300 is formed in the second loop row 410 in the first stroke (a), and in the second stroke (b) It is formed in the under-loop column 500 , and is again formed in the second loop column 410 in the third step (c). Therefore, in this case, the third loop 310 is interwoven with the loops constituting the second loop string 410 in the first stroke (a), and the loops constituting the second loop string 410 in the third stroke (c). It can share the root in a way that is intertwined with However, in the second stroke (b), since there is no first loop or second loop, there is no root to share, so it becomes self-supporting. The self-supporting loop, that is, the self-reliant loop, stands up from the floor structure in a ring shape, so it can perform functions such as arm velcro.

In the present embodiment, since some of the plurality of third loops 310 are formed in the second loop column 410 , the second loop column 410 is formed, and the second loop 210 is vertically adjacent to each other (in the vertical direction). It is to be fixed by being intertwined with the first loops (110). However, since the rest of the plurality of third loops 310 are formed in the underloop row 500 , there is no loop to be woven at the position, and there are no loops to hold up and down, so that they stand on their own.

According to the above-described embodiment, the third loop 310 formed in the under-loop column 500 may be formed in the under-loop column 500 by skipping the second loop 210 .

That is, in the above embodiment, the third loop 310 formed in the first stroke (a) shares a root with the second loop row 410, and the second third loop ( Since the 310 skips the first loop row 400 and is formed in the under-loop row 500 located to the left of the first loop row 400, an independent loop having a sufficient length can be formed.

7(a) and 7(b) of FIG. 7, FIG. 7(b) is the same pattern as FIG. The difference between FIG. 7(b) and FIG. 6 is that the position number is different.

In the tricot knitting machine, FIG. 6 shows the first first yarn 100 drawn out from the first bobbin row, the first second yarn 200 drawn out from the second bobbin row, and the first third drawn out from the third bobbin row. It shows the arrangement of the yarn 300 . And, FIG. 7(b) shows the second first yarn 100 drawn out from the first bobbin row, the second second yarn 200 drawn out from the second bobbin row, and the second third yarn drawn out from the third bobbin row ( 300) is shown.

Also, although not shown in the drawings, the N-th first yarn 100 drawn out from the first bobbin row, the N-th second yarn 200 drawn out from the second bobbin row, and the N-th third yarn drawn out from the third bobbin row Even the arrangement of (300) can be represented.

For simplicity of explanation, only the first and second yarns are indicated for the yarns drawn from each bobbin row.

6, the first yarn of the second yarn 200 returns to position number 1->0 in the first stroke (a) to make a loop, jumps to 2 and goes to 2->3 in the second stroke (b) Return and make a loop again, jump back to 1 and return to 1->0 in the third stroke (c) to make a loop. As the stroke progresses, the position number is 1->0->2->3 It can be seen that the sequence is repeated.

In addition, the first yarn of the first yarn 100 returns to position number 2->3 in the first stroke (a) to make a loop, jumps to 1 and returns to 1->0 in the second stroke (b) Enter and make a loop again, jump back to 2, and return to 2->3 in the third stroke (c) to make a loop. As the stroke progresses, the position number is 2->3->1->0 It can be seen that the sequence is repeated.

In addition, the first yarn of the third yarn 300 returns to position number 1->0 in the first stroke (a) to make a loop, jumps to 3, and returns to 3->4 in the second stroke (b) Enter and make a loop again, jump back to 1, and return to 1->0 in the third stroke (c) to make a loop. As the stroke progresses, the position number is 1->0->3->4 It can be seen that the sequence is repeated.

At this time, the third yarn 300 returns to 3 -> 4 in the second stroke (b), and when making a loop, there is no loop constituting the fabric base on the bottom, so it cannot share the root, so it becomes a self-supporting loop.

Referring to FIG. 7(b) compared to FIG. 6, the second yarn of the second yarn 200 returns to position number 3->2 in the first stroke (a) to make a loop, and jumps to 4 to make the second In stroke (b), return to 4->5 and make a loop again, and then jump back to 3 and return to 3->2 in the third stroke (c) to make a loop. In this case, the position as the stroke progresses The number can be seen as repeating in the order of 3->2->4->5.

In this case, the position number of the first yarn of the second yarn 200 is repeated in the order of 1->0->2->3, whereas the position number of the second yarn is 3->2->4->5 This is repeated in order, but the reason the position numbers are different is because there is an out-traffic. That is, in the present embodiment, this is because there is an out diameter between the first yarn and the second yarn of the second yarn 200 . That is, in the present embodiment, the first yarn and the second yarn of the second yarn 200 have an inner diameter, and the first yarn and the second yarn of the second yarn 200 have an out diameter, so the under loop row between the first and second yarns can be formed. The same may be applied to the first yarn and the second yarn of the first yarn 100 to be described later in this embodiment, and the first yarn and the second yarn of the third yarn 300 may also be equally applied.

Also, the second yarn of the first yarn 100 returns to position number 4->5 in the first stroke (a) to make a loop, jumps to 3 and returns to 3->2 in the second stroke (b) Enter and make a loop again, jump back to 4 and return to 4->5 in the third stroke (c) to make a loop. As the stroke progresses, the position number is 4->5->3->2 It can be seen that the sequence is repeated.

In addition, the second yarn of the third yarn 300 returns to position number 3->2 in the first stroke (a) to make a loop, jumps to 5 and returns to 5->6 in the second stroke (b) Enter and make a loop again, jump back to 3 and return to 3->2 in the third stroke (c) to make a loop. As the stroke progresses, the position number is 3->2->5->6 It can be seen that the sequence is repeated.

At this time, the third yarn 300 returns to 5->6 in the second stroke (b) and becomes a self-supporting loop because there is no loop at the bottom, so it cannot share a root when making a loop.

7(a) is a first yarn, a second yarn, a first yarn, a second yarn, and a third yarn 300 of the first yarn 100 and the second yarn 200 of FIGS. 6 and 7(b). and the second yarn overlaid.

Actually, this is the first yarn and the second yarn of the first yarn 100 and the Nth yarn and the first yarn and the second yarn of the second yarn 200 and the Nth yarn and the first yarn and the second yarn of the third yarn 300 and N Up to the second yarn is possible.

It should be noted here that the loop formed by the first yarn of the third yarn 300 returning around position number 3->4 and the loop formed by the second yarn of the third yarn 300 returning around 5->6 are adjacent. Since there is no loop to do, the loop and the loop are not intertwined, so it is not fixed and becomes an independent loop.

On the other hand, referring to FIG. 2 to form an underloop row 500 between the first loop row 400 and the second loop row 410 , the first yarn 100 is positioned in the first stroke (a). Returning to number 2 -> 3, the first loop 110 is formed, and while going from the first stroke (a) to the second stroke (b), it crosses to position number 3->1 to form an underloop, , in the second stroke (b), the first loop 110 is made while returning to position number 1->0, where the under loop by passing the yarn in the guide of the tricot fabric manufacturing apparatus can be implemented as an under-loop row occupying a position. That is, when the yarn passes through one of the plurality of branch columns of the guide, the underloop column 500 can be implemented by leaving the other adjacent one without passing through.

In the In Out diameter, the In diameter refers to the part where the yarn passes through the guide and the sinker and directly acts on the needle forming the tissue. It exists, but it means that the yarn is not passed through from the pass-through process.

Here, the under loop is, for example, the first loop 110 and the second loop in the process in which the first yarn 100 forms the first loop 110 and proceeds to the next stroke to form the first loop 110 again in the next stroke. 1 means a part connected with a yarn between the loops 110, and the under-loop row 500 does not simply mean an under-loop that forms a floor structure. This may mean that only the under-loop structure is formed because the loop is not continuously formed in the longitudinal direction in which the fabric is woven at a position where the loop of the yarn constituting the fabric base is not formed. For reference, in this embodiment, the yarn constituting the fabric base may include the first yarn 100 and the second yarn 200 , and the yarn forming the self-supporting loop as distinct from this is the third yarn 300 . may include

Here, the guide, sinker, and needle are present in the out pass, but the first yarn 100 and the second yarn 200, which form the bottom structure (under loop) of the fabric, are out (Out) is to prevent the formation of a loop in the position, and as a result, the third loop 310 of the third yarn 300 does not have a loop to be woven in the corresponding out position, so it is not fixed in the end, and the unfixed loop becomes self-supporting it will be a loop

In this specification, the under-loop and the under-loop column 500 are distinguished. The underloop simply means the straight line part of the yarn connecting the loop and the loop, but the underloop row occupies the position, and the straight line part of the yarn connecting the loop and the loop constituting the fabric base runs in the vertical direction. It means an empty loop column to form. That is, the loop of yarn constituting the base of the fabric and the straight line connecting the loop should occupy the position.

8 shows a state in which the fourth yarn forms a loop and an underloop as the stroke progresses. In order to distinguish the under-loop and the under-loop sequence, FIG. 8 and FIG. 2 will be compared and described.

First, looking at FIG. 8 , the fourth yarn returns to position number 1-> 0 in the first stroke (a) as the stroke progresses to make a fourth loop 600 , and moves straight to 0-> 1 while moving straight to the fourth Making an underloop 610, making a fourth loop 620 while returning back to 1->2 in the second stroke (b), making a fourth underloop 630 while moving straight to 2->1 , shows a state in which a fourth loop 640 is made while returning to 1->0, and a fourth under-loop 650 is made while linearly moving from 0->1. Here, although the

fourth underloops

610 , 630 , and 650 are underloops, they do not occupy positions, so they cannot be referred to as underloop rows in the present specification. On the other hand, referring to FIG. 2 , the first loop 110 returning to position number 2->3 in the first stroke (a) and the first loop 110 returning to 1->0 in the second stroke (b) ), the linearly moving part of the first yarn 100 crosses the empty loop row that does not form a loop, and at the same time, the first loop 110 and the second loop 210 are the yarns constituting the base of the fabric. Since it is a loop, this case is defined as an under-loop sequence in this specification.

Since the conventional general tricot loop is woven at an angle, the loop rows formed in the vertical direction are continuously formed along the horizontal direction. This is because both ends of the loop are woven into the yarn constituting the floor structure and fixed to the bottom of the fabric in the form of a knot because all the yarns that make up the floor go through the guide and reach the needle, not through the in-out diameter.

Therefore, a separate process for setting up the loop through the raising process is required. However, in the tricot fabric according to this embodiment, because the yarn constituting the floor structure is passed through in-out, that is, because the portion that is passed through the guide and the portion that is not passed through the guide are arranged at an intersection, an underloop row is formed in the portion that is not passed through, and , since the loop formed in the under-loop row formed in this way is not fixed by the loops constituting the other base base, the unfixed third loop 310 comes out to form an independent loop, and forms a single ring. The self-supporting loop formed in this embodiment can be used for various purposes, but it can be applied to the arm velcro function as an example. For reference, in this specification, the loops of the yarn constituting the base of the fabric are referred to as the first loop 110 and the second loop 210, and the loops of the yarn forming the self-supporting loop without constituting the base of the fabric are referred to as the third loop ( 310).

Another embodiment of the present invention may present an apparatus for manufacturing a tricot fabric in which the above-described method for manufacturing a tricot fabric is implemented.

The apparatus for manufacturing a tricot according to this embodiment includes: a first bobbin row in which a plurality of first bobbins wound with a first yarn 100 are arranged; a second bobbin row in which a plurality of second bobbins around which the second yarn 200 is wound are arranged; a third bobbin row in which a plurality of third bobbins on which the third yarn 300 is wound are arranged;

a first guide bar for guiding the first yarn 100; a second guide bar for guiding the second yarn 200; a third guide bar for guiding the third yarn 300; and a control unit for moving the first guide bar, the second guide bar, and the third guide bar left and right, respectively.

Here, the control unit controls the movement of the first guide bar, the second guide bar, and the third guide bar, so that the first yarn 100, the second yarn 200, and the third yarn 300 form a zigzag loop, respectively. The control is performed so that the first yarn 100 and the second yarn 200 intersect the first loop string 400 and the second loop string 410, respectively, and the third yarn 300 loops. One of them may be controlled to share a root with the first loop sequence 400 or the second loop sequence 410 .

The content of the control of the control unit according to the present embodiment may be substantially the same as the content of the above-described method for manufacturing the tricot fabric. An example of the control unit according to the present embodiment is a pattern wheel. By rotating the wheel on which the pattern is formed, it is possible to control the left and right movements of each of the plurality of guide bars so that a loop row is formed as the above-described stroke proceeds.

Another aspect of the present invention is a tricot fabric manufactured by the above-described method for manufacturing a tricot fabric. Since the manufacturing method of the tricot fabric according to the present embodiment has been described in the above-described embodiment, a detailed description thereof will be omitted.

The second embodiment of the manufacturing method of the tricot fabric

What will be described next is a method for manufacturing a tricot fabric according to another aspect of the present invention.

Before describing another aspect of the present invention, words described in another aspect of the present invention may have different meanings from those described in the above-described embodiments. For example, in the above-described embodiment, the first loop is a loop formed by the first yarn, the second loop is a loop formed by the second yarn, and the first loop and the second loop are alternately woven in the longitudinal direction to form the first loop. Although the row and the second loop row are formed, in this embodiment, the first loop is a loop formed by the first yarn, and a plurality of first loops may be woven in the longitudinal direction to form a first loop array.

In addition, in this embodiment, the second yarn may mean a yarn for making a self-supporting loop, unlike the above-described embodiment. That is, the second yarn in this embodiment is substantially the same as the third yarn in the above-described embodiment. That is, in this embodiment, the yarn constituting the fabric base is indicated as the first yarn, and the yarn forming the self-supporting loop without constituting the fabric base is indicated as the second yarn.

In the present specification, the yarn forming the base of the fabric may mean a yarn that does not form a self-supporting loop and forms the tissue of the fabric, and may mean the first yarn in this embodiment.

In addition, the yarn that does not form the fabric base is not directly related to the formation of the fabric structure, and may mean a fabric in which some loops are provided to form self-supporting loops, and may include the second yarn in this embodiment. .

Referring to Figure 9, another aspect of the present invention is described, in the method of manufacturing a tricot fabric comprising a plurality of longitudinal loop arrays formed in the longitudinal direction using at least one first yarn,

Fabric base forming step in which the first yarn alternately forms a first loop and a first underloop in a zigzag direction as the stroke progresses, and forms a plurality of first loop arrangements and a plurality of first underloop arrangements in a longitudinal direction (S200); and

As the stroke progresses, a second yarn different from the first yarn alternately forms a second loop and a second underloop in a zigzag direction, one of the second loops is formed in the first loop arrangement, The other one of the second loops may provide a method of manufacturing a tricot fabric having a self-supporting loop, including a self-reliant loop forming step (S210) of forming the first under-loop arrangement.

According to an embodiment, the longitudinal direction may be characterized in that the longitudinal direction of the warp of the tricot knitting machine.

In addition, the first yarn is a plurality of doedoe, each of the plurality of first yarn may be arranged at regular intervals in the horizontal direction of the tricot knitting machine.

In addition, the first loop arrangement is formed by the branches of the guide through which the first yarn is passed among the plurality of needles aligned in the transverse direction of the tricot knitting machine, and the first yarn is formed by the branches of the guide through which the first yarn is not passed through. It may be characterized in that the first under-loop arrangement is formed.

In addition, the first yarn and the second yarn may be respectively controlled by different guide bars.

In this embodiment, the first yarn is wound on the bobbin of the tricot knitting machine and pulled in the longitudinal direction to mean a yarn weaved by a configuration such as a guide, a sinker, a needle, and a tongue. Here, the position of the yarn is controlled by the guide controlled by the guide bar, and the yarn is knitted as the stroke progresses.

In the tricot knitting machine, a plurality of bobbins may be connected to one shaft to constitute a bobbin row, and a plurality of such bobbin rows may be provided.

One bobbin may include a plurality of yarns so that at least one yarn is unwound.

In this embodiment, the first yarn may mean a plurality. The first yarn may mean a plurality of yarns unwound from one bobbin, may mean a plurality of yarns unwound from a plurality of bobbins, or may mean a plurality of yarns unwound from a plurality of bobbin rows.

In this embodiment, a plurality of vertical (Y-axis) loop arrangement formed in the vertical direction (Y-axis) forms a loop arrangement while a plurality of loops are woven in the vertical direction (Y-axis), but such a loop arrangement is performed in the horizontal direction ( It may mean that a plurality are formed along the X-axis).

Looking at the configuration of the tricot knitting machine, a plurality of guides having a plurality of branches may be disposed, and each of a plurality of branches and a plurality of needles of these guides are disposed to cross each other in a structure in which a needle is inserted between the branches of the guide. In the structure where the yarn is passed through the guide, a loop may be formed in the guide, and the loop may not be formed in the out tube in which the yarn is not passed through the guide.

For example, 1:1 in-out (IN OUT) diameter may mean a case in which a branch in which the yarn is passed through and a branch in which the yarn is not passed are alternately positioned one by one in the branch row of the guide in which the needles are arranged along the horizontal direction.

In this embodiment, as well as in the case of 1: 1 In Out, 2: 1 In Out, 3: 1 In Out, N: 1 In Out It can include all cases such as 1 : N In Out Tongyeong, N : N In Out Tonggyeong. That is, only an out diameter is needed somewhere, and when one of the loops formed by the second yarn is located in the empty loop row generated due to the out diameter, an independent loop is formed at that position.

The loop is continuously formed as the stroke progresses at the position where the branch in which the guide's yarn is passed is located (in this specification, the position refers to the position of the guide's branch), and in the position where the branch in which the guide's yarn is not passed through is located, the loop is continuously formed. no loop is formed. A loop can be formed in a zigzag manner as the stroke progresses while the guide moves in the horizontal direction by the guide bar at the position where the branch of the guide is located.

Here, forming the loop zigzag means that the first yarn 100 in FIG. 2 returns to the position number 2->3 of the branch of the guide in the first stroke (a) to form the first loop 110 and then 3-> 1 to form an under-loop while linearly moving to the second stroke (b), and returning to 1->0 on the second stroke (b) again to form the first loop 110 can

In this embodiment, the meaning that the first yarn forms the first loop and the first underloop alternately means that the first yarn among the plurality of branches of the guide arranging in the transverse direction of the tricot knitting machine is the branch through which the first yarn is passed through. It may be characterized in that the first loop arrangement is formed by an in diameter, and the first under loop arrangement is formed by a branch in which the first yarn is not passed through, that is, by an out diameter.

Here, the first underloop arrangement has substantially the same meaning as the underloop arrangement in the above-described embodiment, and between the first stroke and the second stroke when the first yarn makes a loop in the first stroke and makes a loop again in the second stroke It may mean that the loop made in and the straight part of the yarn between the loops skips the guide position. That is, when the first yarn forms a loop in the first stroke and moves linearly by the guide while proceeding to the second stroke, it may mean a case in which the loop is formed again in the second stroke after moving beyond the position.

According to an embodiment, the first yarn and the second yarn may be controlled by different guide bars, respectively. one of the second loops forming a first loop with the first yarn forming a first loop and a first loop arrangement, a first underloop and a first underloop arrangement and a second yarn forming a second loop and a second underloop arrangement The loops formed in the loop arrangement and the other of the second loops are formed in the first underloop arrangement, and the loops formed in the first underloop arrangement are not fixed by the members of the adjacent loops. This can be done by control logic.

Another aspect of the present invention provides a tricot fabric manufactured by the manufacturing method according to the above-described embodiment.
