This embodiment will be described with reference to the drawings. It should be noted that the present embodiment is merely an example, and those which have been appropriately modified without departing from the spirit of the present invention shall be included in the scope of the present invention.

1. 1. Embodiment 1
(1) Structure of Warp Knitting Machine The warp knitting machine of the first embodiment includes a front side knitting needle row FN and a back side knitting needle row BN, and the front side base cloth 1 is knitted by the front side knitting needle row FN, and the back side knitting needle is knitted. This is a so-called double raschel machine in which the back side base cloth 2 is knitted by the row BN, and the front side base cloth 1 and the back side base cloth 2 are connected at at least a part of these base cloths. The front side knitting needle row FN and the back side knitting needle row BN are each in which a large number of knitting needles are arranged in a row in the width direction of the double raschel machine. The gauge is, for example, 24E (the number of knitting needles per inch is 24).

Further, as shown in FIG. 1, the double raschel machine of the first embodiment has a pair of jacquard bars JB3 and JB4 on the front side (hereinafter, "front jacquard bars JB3 and JB4") and a pair of jacquard bars on the back side. It is a so-called double jacquard double raschel machine equipped with card bars JB6 and JB7 (hereinafter, "back jacquard bars JB6, JB7").

Jacquard bars JB3, JB4, JB6, and JB7 each carry out basic movements to organize a basic organization. Along with this, a plurality of jacquard guides provided in each of the jacquard bars JB3, JB4, JB6, and JB7 perform basic exercises for organizing a basic organization.

In addition to the basic movements for organizing the basic tissue, each of these jacquard guides can be displaced independently by the action of the jacquard mechanism. Therefore, a plurality of jacquard guides can perform different exercises. When the jacquard mechanism operates, the jacquard guide is displaced by a distance of 1 G (distance between two adjacent knitting needles) from the position during knitting of the basic structure. As for the direction of displacement, the jacquard guides of the front jacquard bars JB3 and JB4 are on the left, and the jacquard guides of the back jacquard bars JB6 and JB7 are on the right. The jacquard mechanism can act only at the time of overlap, at the time of overlap, or at both overlap and overlap.

Further, the double raschel machine of the first embodiment is provided with at least one guide bar on the front side of the front jacquard bars JB3 and JB4, and at least one guide bar on the back side of the back jacquard bars JB6 and JB7. To be equipped with.

In FIG. 1, two guide bars GB1 and GB2 are provided as guide bars on the front side of the front jacquard bars JB3 and JB4, and two guide bars are provided as guide bars on the back side of the back jacquard bars JB6 and JB7. It is equipped with guide bars GB8 and GB9. However, in the knitting of the warp knitted fabric 10, at least one of the two guide bars GB1 and GB2 on the front side may be used, and it is not always necessary to use two of them. Further, in the knitting of the warp knitted fabric 10, at least one of the two guide bars GB8 and GB9 on the back side may be used, and it is not always necessary to use two of them.

Further, the double racquard machine of the first embodiment includes at least one guide bar between the front jacquard bars JB3 and JB4 and the back jacquard bars JB6 and JB7. In FIG. 1, one guide bar GB5 is provided as such a guide bar.

The guide bars GB1, GB2, GB5, GB8, and GB9 each perform basic exercises for organizing the knitting structure. Unlike the jacquard guide, the plurality of guides provided in the guide bars GB1, GB2, GB5, GB8, and GB9 cannot perform different exercises from the other guides provided in the same guide bar.

In each of the guide bars GB1, GB2, GB5, GB8, and GB9, the number of guides per inch is the same as the number of knitting needles per inch. Then, in each of the guide bars GB1, GB2, GB5, GB8, and GB9, each guide is arranged at a position corresponding to each knitting needle.

On the other hand, the jacquard bars JB3, JB4, JB6, and JB7 are half-gauge jacquard bars, respectively. Then, the pair of two jacquard bars makes the whole pair full gauge. That is, in each of the jacquard bars JB3, JB4, JB6, and JB7, the number of jacquard guides per inch is half the number of knitting needles per inch, and one jacquard guide is used for every two knitting needles. Have been placed. Here, the position of the jacquard guide is deviated by one knitting needle between the two jacquard bars in a pair. By pairing the two jacquard bars, the same number of jacquard guides as the number of knitting needles are aligned, and each guide is arranged at a position corresponding to each knitting needle.

Therefore, by pairing the jacquard bars JB3 and JB4, the same number of jacquard guides as the number of knitting needles are prepared, and the jacquard guides are arranged at positions corresponding to the respective knitting needles. Further, by pairing the jacquard bars JB6 and JB7, the same number of jacquard guides as the number of knitting needles are prepared, and the jacquard guides are arranged at the positions corresponding to the respective knitting needles.

In the above reed arrangement, the guide bar GB1 to the back jacquard bars JB6 and JB7 can overlap the front side knitting needle row FN, and the front jacquard bars JB3 and JB4 to the guide bar GB9 overlap the back side knitting needle row BN. It is possible to wrap.

The warp knitting machine of the first embodiment has the same structure as a well-known double raschel machine except for the above structure.

(2) Manufacturing method of warp knitted fabric 10 In the double raschel machine having the above structure, the front side base cloth 1 is knitted by at least one of the guide bars GB1 and GB2 on the front side of the front jacquard bars JB3 and JB4. NS. Further, the back side base cloth 2 is knitted by at least one of the guide bars GB8 and GB9 on the back side of the back jacquard bars JB6 and JB7.

The front jacquard bar JB3, JB4 and the jacquard mechanisms of the back jacquard bars JB6 and JB7 act in parallel with the knitting of the front side base cloth 1 and the back side base cloth 2, respectively. The jacquard thread supplied from JB4 (hereinafter referred to as "front jacquard thread") and the jacquard thread supplied from back jacquard bars JB6 and JB7 (hereinafter referred to as "back jacquard thread") are front. It is woven into the side base cloth 1 and the back side base cloth 2. The jacquard yarn woven into the front side base cloth 1 and the back side base cloth 2 appears on the surface of these base cloths to form a jacquard pattern.

The jacquard pattern is a pattern formed by jacquard threads appearing on the surface of the warp knitted fabric 10.

Further, in parallel with the formation of the jacquard pattern, the jacquard mechanisms of the front jacquard bars JB3 and JB4 and the back jacquard bars JB6 and JB7 act respectively, so that the front jacquard yarn and the back jacquard yarn are warped. The front side base cloth 1 and the back side base cloth 2 are connected to each other at least a part of the knitted fabric 10.

Here, since the connecting position between the front side base cloth 1 and the back side base cloth 2 and the position other than the connecting position (non-connecting position) are formed by the jacquard yarn, each of them is the surface of the warp knitted fabric 10. Corresponds to the components of the jacquard pattern that appear in. For example, when the front jacquard yarn is woven into the back side base fabric 2 and the back jacquard yarn is woven into the front side base fabric 1 to form the connecting portion, the back jacquard yarn is woven into the front side. It appears on the surface of the base cloth 1 and becomes a component of the jacquard pattern on the front surface of the warp knitted fabric 10.

It is desirable that the connected position and the non-connected position extend over a plurality of courses and a plurality of wales, respectively.

Further, in parallel with the formation of the jacquard pattern, the guide bar GB5 between the front jacquard bars JB3 and JB4 and the back jacquard bars JB6 and JB7 is formed between the front side base cloth 1 and the back side base cloth 2. Insert the insertion thread between them. The insertion thread inserted by the guide bar GB5 is pressed and compressed from the front side base cloth 1 and the back side base cloth 2 at the connecting position between the front side base cloth 1 and the back side base cloth 2. On the other hand, at the non-connected position between the front side base cloth 1 and the back side base cloth 2, the insertion thread inserted by the guide bar GB5 is not pressed by the front side base cloth 1 and the back side base cloth 2 and is not compressed. .. Therefore, the portion formed by the non-connected position bulges more than the portion formed by the connected position.

As a result of knitting as described above, on the surface of the warp knitted fabric 10, the portion formed by the connected position becomes a concave portion, and the portion formed by the non-connected position bulges into a convex portion. Since the connected position and the non-connected position are related to the jacquard pattern appearing on the surface of the warp knitted fabric 10, unevenness matching the jacquard pattern is formed on the warp knitted fabric 10.

As one of the preferred forms, the front side guide bar GB1 or GB2 forms a chain knitting structure on the front side base cloth 1, and the back side guide bar GB8 or GB9 forms a chain knitting structure on the back side base cloth 2. Will be done. Further, due to the action of the jacquard mechanism, in each of the front side base cloth 1 and the back side base cloth 2, the position where the front jacquard yarn and the back jacquard yarn connect the adjacent wales of the chain knitting structure and the position where they do not connect. And are formed. On top of that, the position where the adjacent wales on the front side base cloth 1 are not connected and the position where the adjacent wales on the back side base cloth 2 are not connected are in the front-rear direction (the direction perpendicular to the surface of the warp knitted fabric 10, that is, the warp knitting). When it coincides with the front and back directions of the ground 10, a hole penetrating the warp knitted fabric 10 is formed at that position.

(3) Specific organization example 1
An example of knitting the warp knitted fabric 10 as described above will be described. The warp knitted fabric 10 in this knitting example is used, for example, for the upper of shoes.

The organization chart of this knitting example is shown in FIG. In each knitting organization chart, F indicates a course knitted by the front knitting needle row FN, and B indicates a course knitted by the back side knitting needle row BN. In the first embodiment, the guide bars GB2, GB5, GB8, GB9, and the jacquard bars JB3, JB4, JB6, and JB7 are used for knitting.

In this knitting, the guide bars GB2, GB5, GB8, and GB9 are each supplied with a full set of yarns. That is, in each of the guide bars GB2, GB5, GB8, and GB9, the thread is supplied to all the guides. As a result, the same number of yarns as the number of knitting needles in one knitting needle row is supplied to each of the guide bars GB2, GB5, GB8, and GB9.

Further, the front jacquard bars JB3 and JB4 and the back jacquard bars JB6 and JB7 are also supplied so as to have a full set of threads. That is, in each of the jacquard bars JB3, JB4, JB6, and JB7, the thread is supplied to all the jacquard guides. As a result, the same number of yarns as the number of knitting needles in one knitting needle row is supplied to the entire front jacquard bars JB3 and JB4. Further, the same number of yarns as the number of knitting needles possessed by one knitting needle row is supplied to the entire back jacquard bars JB6 and JB7.

As shown in FIG. 2A, the knitting structure of the guide bar GB2 is a chain knitting structure in which stitches are formed in the same wales, and is 0-1 / 1-1 / 1-0 / 0-0 //. It consists of repeating units.

In such a notation, the odd-numbered ones (0-1 and 1-0 in the above example) indicate the action of the front knitting needle row FN on the knitting needles, and the even-numbered ones (above). In the example, 1-1 and 0-0) indicate the action of the back side knitting needle row BN on the knitting needle.

The knitting structure of the guide bar GB5 shown in FIG. 2C is an insertion structure, and is composed of a repeating unit of 0-0 / 1-1 / 1-1 / 0-0 //. The knitting structure of the guide bar GB8 shown in FIG. 2E is a chain knitting structure, and is composed of repeating units of 1-1 / 1-0 / 0-0 / 0-1 //. The knitting structure of the guide bar GB9 shown in FIG. 2 (f) is an insertion structure, and is composed of repeating units of 1-1 / 0-0 / 0-0 / 1-1 / /.

In this way, the guide bar GB2 and the guide bar GB8 form stitches on all the wales and courses of the front side base cloth 1 and the back side base cloth 2. Here, since the knitting structure by the guide bar GB2 and the guide bar GB8 is a chain knitting structure, adjacent wales cannot be connected to each other without the jacquard yarn. As will be described later, jacquard yarns connect adjacent wales.

The insertion thread inserted by the guide bar GB5 plays a role of bulging the warp knitted fabric 10 as described later. Further, the insertion thread inserted by the guide bar GB9 plays a role of reinforcing the warp knitted fabric 10.

FIG. 2 also shows the basic structure of the jacquard bars JB3, JB4, JB6, and JB7, that is, the knitting structure of the jacquard bars JB3, JB4, JB6, and JB7 when the jacquard mechanism does not work. The basic structure of the front jacquard bars JB3 and JB4 shown in FIG. 2B is composed of repeating units of 1-0 / 1-2 / 1-2 / 1-0 //. The basic structure of the back jacquard bars JB6 and JB7 shown in FIG. 2D is composed of repeating units of 1-0 / 1-2 / 1-2 / 1-0 //.

In FIG. 3, the above basic structure by the front jacquard bars JB3 and JB4 is shown by a broken line, and an example of the knitting structure by the front jacquard bars JB3 and JB4 when the jacquard mechanism operates is shown by a solid line. ..

In addition, in each organization chart, H in the figure indicates that the jacquard mechanism does not act. In this case, the jacquard guide is in the same position as when organizing the basic organization. Further, T in the figure indicates that the jacquard mechanism is operated. In this case, the jacquard guide will be displaced from the position where the basic tissue is organized. Although T and H are described in the upper and lower stages of one needle position, the upper stage T or H indicates that the jacquard mechanism is activated or not operated at the time of overlap, and the lower stage T or H indicates that the jacquard mechanism is activated or not operated at the time of underlapping. Indicates that the card mechanism is activated or not activated.

3 (a) and 3 (b) show an example of a knitting structure when the front jacquard bars JB3 and JB4 overlap with the front side knitting needle row FN due to the action of the jacquard mechanism. The knitting structure of FIG. 3A is one of what is called a thick structure, and is composed of repeating units of 1-0 / 2-2 / 2-3 / 1-1 / /. The knitting structure of FIG. 3B is one of what is called a thin structure, and is composed of repeating units of 1-0 / 2-2 / 1-2 / 1-1 / /.

By overlapping the front jacquard bars JB3 and JB4 with respect to the front knitting needle row FN in this way, the front side base cloth 1 is formed by the front jacquard yarn and the yarn supplied from the guide bar GB2. At this time, the front jacquard yarn appears on the surface of the front side base fabric 1 (the surface of the warp knitted fabric 10 on the front side).

Here, when knitting the thick structure of FIG. 3A, the front jacquard yarn reciprocates between three needles in the wale direction (weft direction) in one repeating unit while forming a needle loop, and is reciprocated between three needles in FIG. When knitting the thin tissue of (b), two needles reciprocate in the wale direction in one repeating unit while forming a needle loop. Therefore, the front jacquard yarn connects the wales having different chain knitting structures by the yarn supplied from the guide bar GB2. The thick structure of FIG. 3 (a) is thicker than the thin knitted structure of FIG. 3 (b) because the swing width in the wale direction (weft direction) is larger and the front side base cloth 1 is thicker.

FIG. 3C shows an example of a knitting structure in which the front jacquard bars JB3 and JB4 are wrapped only within the same wales by the action of the jacquard mechanism. The knitting structure of FIG. 3C is one of what is called a hole structure, and is composed of repeating units of 1-0 / 0-1 / 0-1 / 0-0 //.

When knitting the hole structure shown in FIG. 3C, the front jacquard yarn does not connect the adjacent wales of the chain knitting structure by the threads supplied from the guide bars GB2 and GB8. Further, in the hole structure of FIG. 3C, the front jacquard bars JB3 and JB4 overlap with the front side knitting needle row FN and the back side knitting needle row BN, and the front jacquard yarn is the front side base cloth 1 and the front side base cloth 1. It is woven into the back side base cloth 2. Therefore, the front side base cloth 1 and the back side base cloth 2 are connected.

3 (d) and 3 (e) show an example of the knitting structure when the front jacquard bars JB3 and JB4 overlap with the back side knitting needle row BN by the action of the jacquard mechanism. The knitting structure of FIG. 3D is composed of repeating units of 1-1 / 2-3 / 2-2 / 1-0 //. The knitting structure of FIG. 3 (e) consists of repeating units of 1-1 / 1-2 / 2-2 / 1-0 //.

By overlapping the front jacquard bars JB3 and JB4 with respect to the back side knitting needle row BN in this way, the front jacquard yarn is woven into the back side base cloth 2. At this time, the front jacquard yarn appears on the surface of the back side base fabric 2 (the surface of the warp knitted fabric 10 on the back side).

Here, when the front jacquard yarn knits the knitting structure shown in FIG. 3 (d), the front jacquard yarn reciprocates between three needles in the wale direction in one repeating unit while forming a needle loop, as shown in FIG. 3 (e). When knitting a knitted structure, two needles reciprocate in the wale direction in one repeating unit while forming a needle loop. Therefore, the front jacquard yarn connects the wales having different chain knitting structures by the yarn supplied from the guide bar GB8. In the knitting structure of FIG. 3D, the back side base cloth 2 is thicker because the swing width in the wale direction (weft direction) is larger than that of the knitting structure of FIG. 3E.

In FIG. 4, the above basic structure by the back jacquard bars JB6 and JB7 is shown by a broken line, and an example of the knitting structure by the back jacquard bars JB6 and JB7 when the jacquard mechanism operates is shown by a solid line. ..

4 (a) and 4 (b) show an example of the knitting structure when the back jacquard bars JB6 and JB7 overlap with the back side knitting needle row BN by the action of the jacquard mechanism. The knitting structure of FIG. 4A is one of what is called a thick structure, and is composed of repeating units of 1-1 / 2-3 / 2-2 / 1-0 //. The knitting structure of FIG. 4B is one of what is called a thin structure, and is composed of repeating units of 0-0 / 1-2 / 1-1 / 1-0 //.

By overlapping the back jacquard bars JB6 and JB7 with respect to the back side knitting needle row BN in this way, the back side base cloth 2 is formed by the back jacquard yarn and the yarns supplied from the guide bars GB8 and GB9. .. At this time, the back jacquard yarn appears on the surface of the back side base fabric 2 (the surface of the warp knitted fabric 10 on the back side).

Here, the back jacquard yarn reciprocates between three needles in the wale direction in one repeating unit while forming a needle loop when knitting the thick structure of FIG. 4 (a), and the back jacquard yarn reciprocates between three needles in the wale direction, as shown in FIG. 4 (b). When knitting a thin tissue, two needles reciprocate in the wale direction in one repeating unit while forming a needle loop. Therefore, the jacquard yarns supplied from the back jacquard bars JB6 and JB7 connect the wales having different chain knitting structures by the yarns supplied from the guide bar GB8. The thick structure of FIG. 4 (a) is thicker than the thin structure of FIG. 4 (b) because the back side base cloth 2 has a larger swing width in the wale direction (weft direction).

FIG. 4C shows an example of a knitting structure in which the back jacquard bars JB6 and JB7 are wrapped only within the same wales by the action of the jacquard mechanism. The knitting structure of FIG. 4C is one of what is called a hole structure, and is composed of repeating units of 1-0 / 0-1 / 1-1 / 1-0 //.

When knitting the hole structure shown in FIG. 4C, the back jacquard yarn does not connect the adjacent wales of the chain knitting structure by the threads supplied from the guide bars GB2 and GB8. In the hole structure of FIG. 4C, the back jacquard bars JB6 and JB7 overlap with the front side knitting needle row FN and the back side knitting needle row BN, and the back jacquard yarn is on the front side base cloth 1 and the back side. It is woven into the base cloth 2. Therefore, the front side base cloth 1 and the back side base cloth 2 are connected.

4 (d) and 4 (e) show an example of the knitting structure when the back jacquard bars JB6 and JB7 overlap with the front side knitting needle row FN due to the action of the jacquard mechanism. The knitting structure of FIG. 4D is composed of repeating units of 1-0 / 2-2 / 2-3 / 1-1 / /. The knitting structure of FIG. 4 (e) consists of repeating units of 1-0 / 1-1 / 1-2 / 0-0 //.

By overlapping the back jacquard bars JB6 and JB7 with respect to the front side knitting needle row FN in this way, the back jacquard yarn is woven into the front side base cloth 1. At this time, the back jacquard yarn appears on the surface of the front side base cloth 1 (the front side surface of the warp knitted fabric 10).

Here, when the back jacquard yarn knits the knitting structure of FIG. 4 (d), it reciprocates between three needles in the wale direction in one repeating unit while forming a needle loop, and the back jacquard yarn reciprocates between three needles in the wale direction, as shown in FIG. 4 (e). When knitting a knitted structure, two needles reciprocate in the wale direction in one repeating unit while forming a needle loop. Therefore, the back jacquard yarn connects the wales having different chain knitting structures by the yarn supplied from the guide bar GB2. In the knitting structure of FIG. 4D, the front side base cloth 1 is thicker because the swing width in the wale direction (weft direction) is larger than that of the knitting structure of FIG. 4E.

In the first embodiment, one knitting structure in FIGS. 3A to 3E is selected at each knitting position as a knitting structure by the front jacquard bars JB3 and JB4. At the same time, one knitting structure in FIGS. 4A to 4E is selected at each knitting position as the knitting structure by the back jacquard bars JB6 and JB7. In this way, the combination of the knitting structure by the front jacquard bars JB3 and JB4 and the knitting structure by the back jacquard bars JB6 and JB7 is realized at each knitting position.

Depending on this combination, holes can be formed in the warp knitted fabric 10, and specific threads can be made to appear on the front side and back side surfaces of the warp knitted fabric 10. Then, by changing the combination for each knitting position, a jacquard pattern can be formed on the front side and back side surfaces of the warp knitted fabric 10. In addition, unevenness can be formed according to the jacquard pattern.

For example, as the knitting structure by the front jacquard bars JB3 and JB4 at a certain position, a knitting structure that overlaps with the front side knitting needle row FN shown in FIGS. As the knitting structure by the back jacquard bars JB6 and JB7, a knitting structure that overlaps with the back side knitting needle row BN shown in FIGS. 4A or 4B is selected. In this case, the front jacquard yarn appears on the front surface of the warp knitted fabric 10, and the back jacquard yarn appears on the back surface. Further, in this case, the front side base cloth 1 and the back side base cloth 2 are not connected.

Further, as the knitting structure by the front jacquard bars JB3 and JB4 at another position, a knitting structure that overlaps with the back side knitting needle row BN shown in FIG. 3 (d) or (e) is selected and is the same. As the knitting structure by the back jacquard bars JB6 and JB7 at the position, a knitting structure that overlaps with the front side knitting needle row FN shown in FIG. 4D or (e) is selected. In this case, the back jacquard yarn mainly appears on the front surface of the warp knitted fabric 10, and the front jacquard yarn mainly appears on the back surface. Further, in this case, the overlap of the front jacquard bars JB3 and JB4 with respect to the back side knitting needle row BN and the overlap of the pair of back jacquard bars JB6 and JB7 with respect to the front side knitting needle row FN are alternately performed. The sinker loop of the front jacquard thread and the sinker loop of the back jacquard thread intersect and become entangled. As a result, the front side base cloth 1 and the back side base cloth 2 are connected while being attracted to each other.

In this way, a portion where the front jacquard yarn appears and a portion where the back jacquard yarn appears are formed on the front surface of the warp knitted fabric 10. Then, by supplying different types of threads to the front jacquard bars JB3 and JB4 and the back jacquard bars JB6 and JB7, a jacquard pattern is formed on the front surface of the warp knitted fabric 10. Similarly, a portion where the front jacquard yarn appears and a portion where the back jacquard yarn appears are formed on the back side surface of the warp knitted fabric 10. Then, by supplying different types of threads to the front jacquard bars JB3 and JB4 and the back jacquard bars JB6 and JB7, a jacquard pattern is formed on the back surface of the warp knitted fabric 10.

Note that different types of threads are threads in which at least one of color, luster, ease of dyeing, texture, etc. is different.

By the way, the insertion thread inserted by the guide bar GB5 is inserted between the front side base cloth 1 and the back side base cloth 2. Then, at the connecting position where the front side base cloth 1 and the back side base cloth 2 are connected, the insertion thread inserted by the guide bar GB5 is pressed from the front side base cloth 1 and the back side base cloth 2. Is compressed. Therefore, the warp knitted fabric 10 does not swell on either the front side or the back side in the portion including the connection position between the front side base cloth 1 and the back side base cloth 2.

On the other hand, in the non-connected position where the front side base cloth 1 and the back side base cloth 2 are not connected, the insertion thread inserted by the guide bar GB5 cannot be pressed from the front side base cloth 1 and the back side base cloth 2. Not compressed to. Therefore, in the portion where the front side base cloth 1 and the back side base cloth 2 are not connected to each other, the warp knitted fabric 10 bulges to at least one of the front side and the back side.

In this way, unevenness is formed on the surface of the warp knitted fabric 10 in accordance with the jacquard pattern, which is composed of a concave portion which is a non-bulging portion and a convex portion which is a bulging portion.

For reference, FIG. 5 shows how unevenness is formed on the warp knitted fabric 10. As shown in the figure, at the connecting position 5 where the front side base cloth 1 and the back side base cloth 2 are connected by the jacquard thread 3, the insertion thread (not shown) inserted by the guide bar GB 5 is the front side base cloth. It is pressed and compressed from 1 and the back side base cloth 2. On the other hand, at the non-connecting position 6 where the front side base cloth 1 and the back side base cloth 2 are not connected by the jacquard thread 3, the insertion thread 4 is not compressed and the warp knitted fabric 10 is bulged. By forming the bulging position and the non-bulging position in this way, unevenness is formed in the warp knitted fabric 10.

Further, in the portion where the front side base cloth 1 and the back side base cloth 2 are not connected and bulge, the sinker loop of the jacquard thread in the base cloth of either the front side base cloth 1 or the back side base cloth 2. If is longer than the sinker loop of the jacquard yarn in the other base fabric, the warp knitted fabric 10 bulges more on the side of the base fabric having the longer sinker loop.

For example, as the knitting structure by the front jacquard bars JB3 and JB4, the thick structure shown in FIG. 3A in which a stitch is formed on the front side base cloth 1 and reciprocates between three stitches in the wale direction is selected. At the same time, as the knitting structure by the back jacquard bars JB6 and JB7, the thin structure shown in FIG. 4B, which forms a stitch on the back side base cloth 2 and reciprocates between two stitches in the wale direction, is selected. In this case, since the sinker loop of the jacquard yarn in the front side base cloth 1 is longer than the sinker loop of the jacquard yarn in the back side base cloth 2, the warp knitted fabric 10 bulges more toward the front side.

Further, the hole structure shown in FIG. 3 (c) is selected as the knitting structure by the front jacquard bars JB3 and JB4 at a certain position, and the hole shown in FIG. 4 (c) is selected as the knitting structure by the back jacquard bars JB6 and JB7 at the same position. The geological organization is selected. As a result, the unconnected position where the adjacent wales on the front side base cloth 1 are not connected and the unconnected position where the adjacent wales on the back side base cloth 2 are not connected coincide with each other in the front-rear direction, and the position on the warp knitted fabric 10 is adjusted to that position. A hole is formed. Here, since the hole structure of FIG. 3 (c) and the hole structure of FIG. 4 (c) connect the front side base cloth 1 and the back side base cloth 2 as described above, the front is front at the opening end of the hole. The side base cloth 1 and the back side base cloth 2 are connected.

The material and thickness (fineness) of the thread used in the first embodiment are not limited. As the yarn, various yarns such as filament yarn and spun yarn can be adopted. Further, as the material of the thread, natural fibers such as silk and cotton, synthetic fibers made of polyester and nylon, and the like can be adopted.

Further, if the thickness of the insertion thread inserted from the guide bar GB5 changes, the amount of swelling of the warp knitted fabric 10 changes. In order to increase the amount of swelling of the warp knitted fabric 10, it is desirable that the insertion yarn supplied to the guide bar GB5 is thicker than the other yarns, and the constant length type count (dtex) is three times that of the jacquard yarn. The above is more desirable.

For example, the guide bars GB2 and GB8 are supplied with polyester yarn of 100 dtex or less, the guide bar GB9 is supplied with polyester yarn of 100 to 200 dtex, and the jacquard bars JB3, JB4, JB6 and JB7 are supplied with polyester yarn of 100 to 200 dtex. The yarn is supplied, and the guide bar GB5 is supplied with a polyester yarn of 500 to 700 dtex.

The same can be said for the material and thickness of the thread in the following second and third embodiments.

It is formed. The line portion 212 corresponds to a sewn portion in quilting.

(3) Effect In the conventional general manufacturing method of quilting, the front fabric and the back fabric are manufactured individually, and then a core material such as cotton is inserted between the front fabric and the back fabric, and finally. Was sewn in place.

However, according to the third embodiment, the front side base cloth 1 as the front cloth and the back side base cloth 2 as the back cloth are knitted at the same time, and the insertion thread from the guide bar GB5 is inserted as the core material at the same time as the knitting. At the same time, the front side base cloth 1 and the back side base cloth 2 are connected. Therefore, according to the third embodiment, the quilting can be manufactured dramatically and efficiently as compared with the conventional case.

Further, since the holes can be formed in the quilting while knitting as described above, it is possible to manufacture the quilting with holes dramatically more efficiently than in the conventional case.

4. Modification Example The above embodiment is an example, and the scope of the invention is not limited thereto. Various omissions, substitutions, and changes can be made to the above embodiments without departing from the gist of the invention. An example of modification to the above embodiment will be described below.

First, in addition to the shoe uppers and the like already exemplified, the warp knitted fabric of each of the above embodiments includes clothing such as outerwear, interior goods, automobile interior materials, automobile materials such as ceiling materials and seat materials, and hygiene. It can be used for various items such as medical supplies such as materials and medical clothing, bedding, chairs, backpacks and shoulder straps of rucksacks.

Further, the above knitting examples 1 to 3 are merely examples, and various knitting methods other than the knitting examples 1 to 3 can be implemented according to the warp knitting machine of the above embodiment.

Further, in the above embodiment, two color threads are prepared, one color thread is supplied to the front jacquard bars JB3 and JB4, and the remaining one color thread is the guide bars GB2, GB5, GB8, GB9 and the back jacquard. It was supplied to bars JB6 and JB7. However, the number of types of yarns used and the method of supplying those yarns to the jacquard bar and the guide bar are not limited to those of the above embodiment.

For example, three color threads are prepared, one color thread is supplied to the front jacquard bars JB3 and JB4, another one color thread is supplied to the back jacquard bars JB6 and JB7, and the remaining one color thread is supplied. Is supplied to the guide bars GB2, GB5, GB8, and GB9.

Further, for example, the front jacquard bars JB3 and JB4 or the back jacquard bars JB6 and JB7 are supplied with multicolored threads so that the colors change in the width direction of the jacquard bars. In this case, a jacquard pattern whose color changes in the width direction (weft direction) of the warp knitted fabric is formed.

Further, in each of the above embodiments, the weft can be inserted as an insertion thread between the front side base cloth 1 and the back side base cloth 2 by using the same structure as the weft insertion Raschel machine. As a result, the weft yarn and the insertion yarn inserted by the guide bar GB5 are inserted between the front side base cloth 1 and the back side base cloth 2, so that the warp knitted fabric can be further expanded. can. However, if the weft is inserted between the front side base cloth 1 and the back side base cloth 2, all the adjacent wales are connected to each other, so that a hole cannot be formed in the warp knitted fabric.

Further, two or more guide bars may be provided between the pair of jacquard bars on the front side and the pair of jacquard bars on the back side.
