Here, there is a second such as a shoe upper (second knitted fabric portion) of the upper (first knitted fabric portion) or a cover (second knitted fabric portion) of a knitted garment (first knitted fabric portion). The knitted fabric portion is preferably a case where it is easy to rotate the portion where the first knitted fabric portion and the second knitted fabric portion are joined as the rotating shaft with respect to the first knitted fabric portion. However, in the joining by the overlapping yarn loops, one of the overlapping loops and the other loop restricts the movement of each other, so that it is difficult for the second knitted fabric portion to be rotated relative to the first knitted fabric portion.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a first knitted fabric portion and a second knitted fabric portion that are overlapped in a thickness direction, so that a joint portion of the two knitted fabric portions can be used as a rotating shaft. a braid that is joined by a swirling method. Further, another object of the present invention is to provide a first knitted fabric portion and a second knitted fabric portion which are superposed in the thickness direction and which are capable of being easily rotated by being able to rotate the joint portion of the two knitted fabric portions as a rotating shaft. The joining method of the braid.

The knitted fabric of the present invention is obtained by joining a first knitted fabric portion and a second knitted fabric portion which are overlapped in a thickness direction in an independent two-layer state. In the knitted fabric, when the n, m is an arbitrary natural number, the passing portion is supplied to each of the n-th knitting wefts of the second knitted fabric portion in the yarn loop gap from the yarn loop One of the first knitted fabric portions passes to the other surface side, and the first knitted fabric portion is exchanged with the upper and lower positions of the second knitted fabric portion in the thickness direction. Further, the end portion of the second knitted fabric portion is subjected to a detachment prevention treatment in the vicinity of the passing portion of the first knitted fabric portion, thereby the first knitted fabric portion and the second knitted fabric portion Engage at the position of the passing portion. Here, the yarn loop gap is composed of two yarn loops adjacent to the m-th knitting weft of the first knitted fabric portion, a sinker loop connecting the adjacent yarn loops, and the m+1th weave. A gap surrounded by a slat of a latitude ring. The sinker loop of the m+1th weft knitting loop is a plurality of yarn loops adjacent to the mth weft knitting loop which are connected to the two yarn loops which are continuous in the direction of the loop.

<Embodiment 1>

In the first embodiment, the upper 1 (see Fig. 1) having a portion knitted by the joining method of the knitted fabric of the present invention will be described. The position at which the joining method of the woven fabric of the present invention is applied is a portion in which the following instep cover 2 and the tongue 4 are joined. Hereinafter, each configuration of the upper 1 will be described, and then the manufacturing procedure of the upper 1 will be described. Finally, the specific procedure of joining the instep cover 2 to the tongue 4 will be described.

"Shoe noodles"

The upper 1 is a knitted fabric knitted by a flat knitting machine, and has an instep cover 2 covering the back side portion of the wearer's foot and a sole cover 3 covering the sole portion of the wearer.

A shoe opening portion 5 is formed above the instep cover 2, and the shoe opening portion 5 is composed of a shoe opening 5i into which the wearer inserts the foot, and a slit 5s extending from the shoe opening 5i toward the toe side. A tongue 4 is provided at a position of the slit 5s, and a shoehole 6 is provided at a position facing the slit 5s of the instep cover 2.

In the upper 1 of the present example, the configuration in which the instep cover (first knitted fabric portion) 2 and the tongue (second knitted fabric portion) 4 are joined is different from the conventional one. Hereinafter, the configuration of the joint portion between the instep cover 2 and the tongue 4 will be described in detail with reference to the II-II cross-sectional view of FIG. 2A and the yarn loop diagram of FIG. 2B.

The left side of the paper surface of Fig. 2A is the front side (one side) of the instep cover 2, and the right side is the back side (the other side) of the instep cover 2, the upper side is the toe side, and the lower side is the heel side. As shown in FIG. 2A, at the joint portion of the present example, the beginning end portion 2x and the end portion 2y of the instep cover 2 in the warp direction At a position therebetween, a passing portion 7 is formed in which the loop of the weft knitting loop between the beginning end portion 4x and the end portion 4y of the tongue 4 is passed from one side of the back cover 2 to the other side. The shorter the portion of the tongue 4 disposed on the back side of the instep cover 2, the more difficult it is for the tongue 4 to come into contact with the back of the wearer, so that the wearing comfort of the upper 1 of Fig. 1 is better.

Next, the state of the yarn loop in the vicinity of the joint portion including the passing portion 7 will be described based on the yarn loop diagram of Fig. 2B. In Fig. 2B, the instep cover 2 is shown in thin lines, and the tongue 4 is shown in thick lines. As shown in the figure, at the passing portion 7, the respective loops 4a to 4d of the nth knitting weft 4A of the tongue 4 pass through the loop gap of the instep cover 2 (n is an arbitrary natural number), and there is no instep cover. The portion of the loop of 2 that overlaps the loop of the tongue 4. The yarn loop gap through which the respective yarn loops 4a to 4d pass is the two yarn loops 2a, 2b to 2d, 2e adjacent to the mth weft knitting loop 2A of the first knitted fabric portion 2, and the adjacent yarn loop 2a, The gap between the 2b~2d, 2e-joined skein ring and the m+th woven weft ring 2B (m is an arbitrary natural number). In this example, the positions of the respective loops 4a to 4b of the tongue 4 are completely different. Therefore, the loop of the instep cover 2 and the loop of the tongue 4 are alternately one after another in a manner of engagement of the molars. Here, a plurality of yarn loops (for example, the yarn loops 4a, 4b) may be passed through one yarn loop gap.

The m+1th weft knitting ring 2B composed of the new yarn loops 2f to 2j is formed in the warp direction of the yarn loops 2a to 2e of the instep cover 2, and is in the warp direction of the yarn loops 4a to 4d of the tongue 4. The n+1th weft knitting ring 4B composed of the new yarn loops 4f to 4i is formed. By the weaving wefts 2B, 4B, the instep cover 2 and the tongue 4 are joined without falling off. For example, if the n+1th weft knitting ring 4B of the tongue 4 is subjected to the anti-stripping treatment in advance, even if the tongue 4 is stretched toward the front side, the sinker loop of the weft knitting 4B is hooked on the instep cover. 2, so the tongue 4 will not fall off the instep cover 2. Furthermore, the weft knitting loop for preventing the off-line of the tongue 4 is not limited to the n+1th weave. Latitude 4B.

As described above, in the upper 1 of the present example, the instep cover 2 is engaged with the tongue 4 by exchanging the instep cover 2 with the upper and lower positions of the instep cover 2 in the thickness direction of the tongue portion 4. Therefore, the tongue 4 can be easily rotated by using the instep cover 2 and the passing portion 7 of the tongue 4 as a rotating shaft. In the case of the upper 1 of the present example shown in Fig. 1, since the tongue 4 is easily swung toward the front side of the paper, the upper 1 is easily inserted into the upper.

Further, by joining the instep cover 2 to the tongue 4 by exchanging the positions in the thickness direction, there is also an effect that even if the instep cover 2 and the tongue 4 are knitted with knitting yarns of different colors, the vicinity of the passing portion 7 can be suppressed. The color is blurred.

"The manufacturing order of the upper"

The upper 1 of the present example is obtained by combining the sole cover 2 to which the instep cover 2 of the tongue 4 is joined and the instep cover 2 prepared separately from the instep cover 2 by using a flat knitting machine. It is also possible to woven the instep cover 2 integrally with the sole cover 3, unlike this example. As the flat knitting machine, two needle bed flat knitting machines or four needle bed flat knitting machines having one needle bed and one other needle bed in the forward and backward directions can be used. When knitting the instep cover 2 and the tongue 4, a knitting yarn or the like containing a hot melt yarn can be used. Preferably, at least a portion of the instep cover 2 and the tongue 4 are formed into a thick-walled woven structure by knitting using a front and rear needle bed (for example, a combination of a cylindrical knitting and a rib knitting).

The instep cover 2 and the tongue 4 can be woven in the order shown in the knitting concept diagram of FIG. The hollow arrow in the figure shows the traveling direction of the weaving (the direction of the loop), and the horizontal line in each of the portions 2, 4 shows the knitting width direction (the direction in which the yarn loops are arranged). Further, in Fig. 3, a lowercase letter is attached to a portion which is a main portion of the knitting.

First, the heel cover portion 20 which is a part of the instep cover 2 is knitted. Behind the feet The cover portion 20 is configured to set the portion of the heel side of the instep cover 2 to the shape conforming to the shape of the wearer's foot, and the knitting width on the side of the shoe opening portion 5 is narrowed. The line a-b in the figure is the needle-increasing portion of the heel cover portion 20, the line c-d is the needle-retracting portion, and the line b-d and the line a-c are the side edges in the knitting width direction.

Next, the left side portion of the body portion 21 is started to be knitted immediately after the side edge a-c of the heel cover portion 20 (the yarn ring indicated by the V mark), and the right side portion of the body portion 21 is knitted starting immediately after the side edge b-d of the heel cover portion 20. The left end portion and the right side portion of the main body portion 21 are knitted by using different yarn supply ports. The left side portion and the right side portion of the main body portion 21 are knitted in a state in which the needle bed is arranged side by side. Further, the tongue 4 is knitted independently of the main body portion 21 by using a yarn supply opening different from the main body portion 21 (the line e-f is the beginning end of the tongue 4). Then, after the instep cover 2 is engaged with the tongue 4 at the position of the line g-h, the instep cover 2 is completed.

"Joining method"

The procedure for joining the instep cover 2 (first knitted fabric portion) and the tongue 4 (second knitted fabric portion) will be described based on the knitting step diagram of Fig. 4 . The "S+ number" in Fig. 4 shows the serial number of the knitting step, and the black dot in the right column shows the knitting needle of the front needle bed (FB) and the rear needle bed (BB). The symbols in the figures are identical to the symbols in Figure 2B.

In S0, it is shown that the nth knitting weft 4A (including the yarn loops 4a to 4d) of the tongue 4 is locked to the knitting needle of the FB and the mth knitting weft 2A of the instep cover 2 (including the yarn loop 2a~) 2e) The state of the knitting needle stuck in BB. From this state, the tongue 4 is exchanged with the front and rear positions of the instep cover 2. Here, the nth weft knitting ring 4A is preferably a weft knitting ring which is a final stage of the tongue 4, or a knitting weft ring before the first to fifth stages. Further, the mth weft knitting ring 2A is preferably a weft knitting ring of No. 1 to No. 5 immediately following the needle raising portion (starting end portion 2x) of the instep cover 2. As a result, as shown in FIG. 2A, the end portion 4y of the tongue 4 and the beginning end portion 2x of the instep cover 2 are disposed at the passing portion 7. nearby.

In S1, BB is shifted by 1 pitch in the right direction, and the yarn loop 2e locked to the right end of the BB foot back cover 2 is moved to FB. Then, in S2, the yarn loop 4d locked to the right end of the tongue 4 of the FB is moved to the knitting needle of the BB which becomes the empty needle due to the movement of the yarn loop 2e of the instep cover 2 in S1.

In S3, the yarn loop 2d locked to the right end of the foot back cover 2 of the BB is moved to the knitting needle of the FB which becomes the empty needle due to the movement of the yarn loop 4d of the tongue 4 in S2. Then, in S4, the yarn loop 4c locked to the right end of the tongue 4 of the FB is moved to the knitting needle of the FB which becomes the empty needle due to the movement of the yarn loop 2d of the foot back cover 2 in S3.

Thereafter, the knitting ring that moves the one end side (right end side) of the instep cover 2 to the FB which becomes an empty needle due to the movement of the yarn loop of the tongue 4 (corresponding to the knitting of S3), and the tongue are repeatedly The one end side (right end side) yarn loop moves to the knitting needle of the BB which becomes an empty needle by the movement of the yarn loop of the instep cover 2 (the same knitting as S4). As a result, as shown in S5, the instep cover 2 and the front and rear positions of the tongue 4 are exchanged, as shown in Fig. 2B, the loops 4a to 4d of the tongue 4 pass through the adjacent loops 2a, 2b of the instep cover 2 Between 2d and 2e, it is in a state in which one side of the instep cover 2 passes to the other side.

After S5, the n+1th weft knitting ring 4B of the nth weft knitting ring 4A of the tongue 4 of the knitting needle of the BB is knitted (refer to FIG. 2B), and the knitting is immediately followed by the FB. The m+1th weft knitting ring 2B of the mth knitting weft 2A of the foot back cover 2 of the knitting needle 2 (refer to FIG. 2B). The two new weaving wefts 2B, 4B are independently woven. The n+1th weft knitting ring 4B of the tongue 4 can be subjected to the anti-stripping treatment by a press ring or the like, or can be continuously knitted in the warp direction of the n+1th weft knitting ring 4B (for example, 1). ~5 paragraph) after weaving the latitude Weaving the weft ring to prevent the off-line treatment. The engagement of the instep cover 2 with the tongue 4 is determined by the anti-offline treatment.

Here, the n-th knitting weft 4A of the tongue 4 in S5 may be subjected to a pressing process. Further, as the anti-stripping treatment other than the press ring, the final weft knitting of the tongue 4 is knitted by the knitting yarn which is shrunk by heat, and the tongue 4 is heat-treated.

"Modification"

In FIG. 4, the engagement of the instep cover 2 with the tongue 4 is determined after the instep relationship between the instep cover 2 and all of the loops of the tongue 4 is exchanged. On the other hand, each time the yarn loop of the instep cover 2 is exchanged with the front and rear positions of the loop of the tongue 4, a new loop of the yarn loop of the tongue 4 is knitted. Further, the yarn loop of the tongue 4 may be subjected to a loop process every time the yarn loop of the instep cover 2 is exchanged with the front and rear positions of the loop of the tongue 4. Alternatively, the loop of the instep cover 2 and the front and rear positions of the loop of the tongue 4 may be exchanged at one time.

Further, the joint portion similar to that of Fig. 2B can be formed by the intersection of the knitting yarns which are generated in the front and rear relationship of the yarn supply opening. When the yarn is supplied to the FB by the yarn supply opening on the BB side, the yarn is supplied to the BB side by the yarn supply opening on the FB side, and the knitting yarns supplied from the two yarn supply ports between FB and BB cross each other. Therefore, by operating the two yarn feeders by the loop of the tongue 4 between the adjacent loops of the instep cover 2, the same joint portion as that of Fig. 2B can be formed.

<Embodiment 2>

The application range of the joining method of the knitted fabric of the present invention is not limited to the upper. For example, in the case of forming a pocket with a cover for a knitwear, the joining method of the knit of the present invention can be applied when the cover is joined to the upper body portion. Further, it is also possible to knit an industrial material other than a shoe upper or a knit garment by using the joining method of the knitted fabric of the present invention.
