Disclosure of Invention

In a conventional knitting method, a plurality of stitches separated in a knitting width direction sandwich a thread from front to back to hold the thread on a knitted fabric, and therefore the thread is arranged so as to pass through the knitted fabric. The thread material having such an arrangement is exposed on both the front and back sides of the knitted fabric. Therefore, it is difficult to satisfy the demand for hiding the thread on the reverse side of the knitted fabric, for example. Further, in the conventional knitting method, since the front side and the back side of the thread are sandwiched only by the stitches, there is also a problem that the position of the thread in the knitted fabric is easily deviated.

In view of the above-described problems, an object of the present invention is to provide a knitting method capable of firmly fixing a thread material to a knitted fabric without exposing the thread material to the front surface of the knitted fabric.

< 1 > the present invention provides a knitting method for fixing a thread material to a knitted fabric using a weft knitting machine having a first needle bed and a second needle bed opposed to each other with a needle bed gap therebetween,

performing an operation of fixing the thread material using a fixing yarn supplied from a first thread feeder provided in the weft knitting machine in a state where a first loop row which is a part of the knitted fabric is hooked on the first needle bed,

the operation has the following steps:

step A, knitting a first loop on an empty needle of the first needle bed or the second needle bed;

step B, knitting a second coil on the empty needle different from the step A;

a step C of knitting a third coil continuously in the wale direction of the first coil;

a step D of overlapping the third coil with the loops of the first coil row to form a state in which a portion of the fixed yarn connecting the second coil and the third coil crosses the tooth gap;

step E, the wire is arranged at the tooth mouth;

step F of knitting a fourth stitch continuously in the wale direction of the second stitch; and

a step G of overlapping the fourth coil in the coils of the first coil row and winding a portion of the fixed yarn connecting the fourth coil and the third coil around the wire material,

the first coil is a torsion coil.

< 2 > As an embodiment of the knitting method of the present invention, there can be mentioned the following embodiments:

at least one of the second coil, the third coil, and the fourth coil is a torsion coil.

< 3 > As an embodiment of the knitting method of the present invention, there can be mentioned the following embodiments:

the following step X is provided between the step E and the step F: and forming tucks on the coils of the first coil array.

< 4 > As an embodiment of the knitting method of the present invention, there can be mentioned the following embodiments:

in the step G, the fourth coil is disposed between the wire and the first coil row.

[ Effect of the invention ]

In the knitting method of the present invention, the thread material is fixed to the knitted fabric via the fixing yarn fixed to the knitted fabric. Therefore, the thread material is not exposed on the side opposite to the side of the knitted fabric to which the fixed yarn is fixed. In the knitting method of the present invention, the fixed yarn is firmly fixed to the knitted fabric, and the fixed yarn is wound around the thread material. Therefore, the thread is difficult to separate from the knitted fabric, and the position of the thread in the knitted fabric is difficult to be deviated.

Twisting a coil is a difficult coil to unwind. This is because the twist loops become small and become knots when the fixed yarn is stretched. Therefore, according to the knitting method of the above-described form < 2 >, the fixed yarn is more firmly fixed to the knitted fabric.

According to the knitting method of the above-described mode < 3 >, the fourth stitch is easily knitted by fixing the fixing yarn to the hook of the knitting needle by tucking before the fourth stitch is knitted on the second stitch. In particular, in the case where the second coil is not a twisted coil but a hanging coil, forming a tuck is effective. In addition, the portion of the fixed yarn extending from the third coil to the tuck is wound around the wire, and the wire is firmly held by the fixed yarn.

According to the knitting method of the above-described form < 4 >, the wire is sandwiched between the third and fourth coils and the tuck. As a result, the holding of the thread material by the fixing yarn becomes stronger.

Detailed Description

< embodiment 1 >

In embodiment 1, a knitting example in which a thread material is fixed to a knitted fabric using a two-bed flat knitting machine will be described as a knitting method of the present invention. In the following description, the front needle bed of the two-bed flat knitting machine is denoted by FB, and the rear needle bed is denoted by BB. In this example, BB is the first needle bed, and FB is the second needle bed. Of course, the knitting method of the present invention can be carried out using a four-bed flat knitting machine. In this case, the lower back needle bed and the upper back needle bed are the first needle bed, and the lower front needle bed and the upper front needle bed are the second needle bed.

The thread material in this example is a knitting yarn that can be fed from a yarn feeder, but is not suitable for knitting. Examples of such a knitting yarn include a thick and thin knitting yarn that cannot be accommodated in a hook of a knitting needle of a flat knitting machine, a chenille yarn that is easily caught by the hook, and a wide tape yarn such as a ribbon.

The knitting method of this example will be specifically described with reference to fig. 1. The "S + number" in fig. 1 indicates the number of the knitting step. The black dots indicate the needles and the capital letters indicate the positions of the needles FB, BB. The circle symbols represent the stitches of the knitted fabric 1. The colored circle symbol in S8 indicates the stitches of the knitted fabric 1 knitted in S8. The inverted triangle symbol indicates a first thread feeder 8 for feeding the fixed yarn 2 to the needle bed gap 1G and a second thread feeder 9 for feeding the thread material 3 to the needle bed gap 1G. The straight arrow in the up-down direction indicates the movement of the coil, and the straight arrow in the left-right direction indicates the movement direction of the second wire feeder 9.

S1 shows a state where the coils of the first coil array 10 are hooked to BB. The first row of loops 10 is a part of the knitted fabric 1. The knitted fabric 1 of this example is a single-piece knitted fabric such as a handkerchief. In this knitted fabric 1, the side on the BB side in the relative direction between FB and BB is the front side, and the side on the FB side is the back side. In this example, the thread material 3 is fixed to the back surface of the knitted fabric 1 in the subsequent knitting step. Unlike this example, the knitted fabric 1 may be a tubular knitted fabric. When the thread material 3 is fixed to the tubular knitted fabric, a four-bed flat knitting machine is preferably used. In the case of a four-bed flat knitting machine, the stitches of the tubular knitted fabric are not thickened.

In S1, the first yarn feeder 8 that feeds the fixed yarn 2 is moved to knit the first loop 21 with the knitting needle B that is an empty needle FB (corresponding to step a). The first stitch 21 is a twisted stitch formed when the first yarn feeder 8 is moved to the right to pass the knitting needle B and then moved to the left. Here, the fixed yarn 2 of the present example is a knitting yarn different from the knitting yarn constituting the knitted fabric 1. Unlike this example, the fixed yarn 2 may be the same as the knitting yarn constituting the knitted fabric 1. That is, the following steps may be performed using a yarn feeder for knitting the knitted fabric 1. In this case, the fixed yarn 2 becomes inconspicuous, and the thread end processing of the fixed yarn 2 is not required.

In S1, the second stitch 22 is knitted on the knitting needle D of the empty needle FB (corresponding to step B). The second coil 22 in this example is a torsion coil. The second coil 22 may also be a hanging loop. The second coil 22 formed of the loop is twisted when moving to BB in S3 described later, and becomes a twisted coil.

In S2, the third coil 23 continuing in the wale direction of the first coil 21 is knitted (corresponding to step C). The third coil 23 in this example is a twisted coil. It is also possible, unlike the present example, that the third coil 23 is a winding that is not a torsion coil.

In S3, the third stitch 23 is overlapped with the stitch 13 (see S1) of the first stitch row 10 hooked on the knitting needle B of BB (corresponding to step D). By moving the third coil 23, which is a twisting coil, from FB to BB, the third coil 23 is further twisted. That is, the third coil 23 is twisted twice. In addition, the portion of the fixed yarn 2 connecting the second coil 22 and the third coil 23 crosses the tooth gap 1G.

In S4, the second wire feeder 9 is moved to dispose the wire rod 3 at the tooth gap 1G (corresponding to step E). The wire 3 crosses over the fixed yarn 2 connecting the second coil 22 and the third coil 23.

In S5, the first yarn feeder 8 is moved to the left side of the knitting needle C and then moved to the right side to form a tuck 29 in the stitch 19 (see S1) of the first stitch row 10 hooked on the knitting needle C of BB (corresponding to step X). Tuck 29 overlaps knitted fabric 1 across the near side of thread 3, that is, across the opposite side of knitted fabric 1 to thread 3. The fixed yarn 2 connecting the third coil 23 and the tuck 29 is wound around the wire 3. More specifically, the portion of the fixed yarn 2 from the third coil 23 toward the tuck 29 extends from the inner side toward the front side of the wire 3, and the wire 3 is wound by half a turn from below the wire 3. Since the tuck 29 is formed to fix the yarn 2 to the hook of the knitting needle C, the fourth stitch 24 can be easily knitted in the following S6.

In S6, the fourth coil 24 is knitted continuously in the wale direction of the second coil 22 (corresponding to step F). The fourth coil 24 in this example is a loop. The fourth coil 24 may be a twisted coil, unlike this example.

In S7, the second yarn feeder 9 is moved to the left of the knitting needle D, and then the fourth loop 24 is moved to the knitting needle D of BB (corresponding to step G). Further, in S7, the second wire feeder 9 is moved to the right direction. The fourth coil 24 is twisted by moving from FB to BB, and becomes a twisted coil. In S7, the fourth coil 24 is disposed inside the thread material 3, that is, between the thread material 3 and the knitted fabric 1. Here, the third coil 23 knitted at S2 is arranged inside the wire 3, and the tuck coil 29 knitted at S5 crosses the near side of the wire 3. Therefore, the wire 3 is sandwiched between the third coil 23 and the fourth coil and the tuck coil 29. In addition, the portion of the fixed yarn 2 connecting the third coil 23 and the tuck 29, and the portion connecting the tuck 29 and the fourth coil 24 are wound around the wire 3. More specifically, the portion of the fixed yarn 2 from the tuck 29 toward the fourth stitch 24 extends from the near front side to the inside side of the wire 3, and the wire 3 is wound by half a turn from below the wire 3. As a result, the holding of the thread material 3 by the fixed yarn 2 becomes stronger.

The knitting of S1 to S7 may be performed a plurality of times at different positions in the knitting width direction. For example, knitting may be performed at positions S1 to S7, not shown, on the right side of the knitting needle D in fig. 1.

In S8, a yarn feeder, not shown, is operated to knit a new first stitch row 10. As a result, the fixed yarn 2 is firmly fixed to the first coil row 10.

According to the knitting method shown in fig. 1, the thread 3 is fixed to the knitted fabric 1 via the fixing yarn 2 fixed to the knitted fabric 1. Therefore, the thread material 3 is not exposed on the BB side surface of the knitted fabric 1, that is, the front surface side surface of the knitted fabric 1. Further, since the fixed yarn 2 wound around the thread 3 is firmly fixed to the knitted fabric 1, the thread 3 is less likely to be detached from the knitted fabric 1 and is less likely to be displaced from a predetermined position of the knitted fabric 1.

As a first modification of embodiment 1, in S7, only the fourth coil 24 may be moved without moving the second wire feeder 9. In this case, the wire 3 is sandwiched between the third coil 23 and the tucks 29 and the fourth coil 24.

As a second modification of embodiment 1, S5 may be omitted. In this case, after S4, the fourth coil 24 is knitted continuously in the wale direction of the second coil 22. Then, in S7, the wire 3 is not moved, and the fourth coil 24 may be overlapped on the coil 14 of the first coil row 10. In this case, the wire 3 is sandwiched between the third coil 23 and the fourth coil 24.

< embodiment 2 >

The thread material 3 is not limited to the knitting yarn. For example, the thread material 3 may be a thread material which may be damaged by a hook caught by a knitting needle, a thread material which may damage a hook, or the like. Examples of the wire material that may be damaged include an rfid (radio frequency identification) yarn. The RFID yarn is a knitting yarn in which a plurality of communication units are arranged at intervals in the extending direction of the knitting yarn. The communication unit includes an ID chip and an antenna. If the hook hooks the ID chip, there is a fear that the ID chip is damaged. If the hook bends the antenna, there is a fear that the communication performance of the antenna is degraded. In the knitting method of this example, the thread material 3 is not caught by the hook of the knitting needle. Therefore, even such a thread material that is easily damaged can be fixed to the knitted fabric 1 by the knitting method of this example.

Examples of the wire material that may damage the hook include hard wire materials such as metal wires and monofilament yarns. In the knitting method of this example, the thread material 3 is not caught by the hook of the knitting needle. Therefore, even with such hard thread materials, the knitting method according to the present example can be fixed to the knitted fabric 1.

Here, the wire may be in a form that cannot be supplied from the wire feeder. Examples of such a form include a form in which the length of the wire rod is short, a form in which the thickness of the wire rod is too large, and a form in which the wire rod cannot be bent. In this case, the flat knitting machine may be equipped with a mechanism for supplying the wire material to the needle bed gap. Examples of such a structure include a robot hand which holds the wire and arranges the wire at the tooth gap.
