Description

  The present invention relates to a method for preventing unraveling of a knitting yarn so that a knitting yarn surplus portion generated by switching the knitting yarn during knitting of the knitted fabric is not unraveled when knitting the knitted fabric using a flat knitting machine.

  In a knitted fabric having a stripe pattern or an intarsia pattern, the knitting yarn is switched during the knitting of the knitted fabric. The portion where the knitting yarn is switched includes a yarn insertion portion for introducing the knitted yarn after switching to the knitted fabric portion knitted with the knitting yarn before switching, and the end of the knitting fabric portion knitted with the knitting yarn before switching. There is a yarn take-out portion for drawing out the knitting yarn, and it is necessary to prevent the knitting yarn from being unwound at the yarn inserting portion and the yarn take-out portion. The present applicant has proposed a knitting yarn unclamping method that causes the flat knitting machine to perform the unclamping (see, for example, Patent Document 1).

In Patent Document 1, when a knitted fabric is knitted using a flat knitting machine having a knitting needle having a transfer blade on one side surface of a needle body having a hook, a knitting yarn end that is generated when the knitting yarn is switched. A method for unwinding a knitting yarn for unwinding a portion is disclosed. More specifically, in the knitting width direction of each needle bed, the side where the blades of the knitting needles are disposed is defined as the blade side, and the side where the blades are not disposed is defined as the reverse blade side, and the following [1] to [3] Is doing.
[1] The yarn feeder is moved from the blade side to the reverse blade side, and a specific stitch that is one of the stitches of the existing knitted fabric portion that is locked to the needle bed is split, and the first drawn out from the specific stitch Create a new stitch.
[2] Using the same yarn feeder as in [1] above, knitting a second new stitch continuous in the wale direction of the specific stitch.
[3] The first new stitch and the second new stitch are overlapped.

  Here, the split increase is the movement of the stitches P pulled out from the stitches P while moving the stitches P locked to the knitting needles XX of the needle beds X to the knitting needles YY of the needle beds Y facing the needle beds X. This is a known knitting technique for knitting to XX.

JP 2014-156669 A

  According to the method for preventing unraveling of a knitting yarn disclosed in Patent Document 1, the remaining end of the knitting yarn can be firmly unraveled, but if the strength of the knitting yarn to be unraveled is low, the knitting yarn breaks in the middle of unraveling knitting. There was a case.

  The present invention has been made in view of the above circumstances. The purpose of the present invention is to prevent the knitting yarn from breaking when the knitting yarn surplus end is released. As in Patent Document 1, the knitting yarn surplus end is firmly released. An object of the present invention is to provide a method for preventing unraveling of knitting yarn.

  The present inventors have studied various causes of knitting yarn breakage by the method for preventing unraveling of a knitting yarn of Patent Document 1. As a result, when forming the first new stitch by splitting a specific stitch, we obtained knowledge that the cause is that the yarn feeder is moved from the blade side to the reverse blade side to increase the split. It was. When the yarn feeder is moved from the blade side to the reverse blade side and the split is increased, the sinker loop of the first new stitch (the portion connecting the stitches) is entangled so as to bind the two sinker loops of the specific stitch ( (See S1 in FIG. 1 of Patent Document 1). While the knitting yarn is firmly unwound due to the entanglement between the sinker loops, the knitting yarn becomes difficult to move, so that a large tension acts on the knitting yarn when forming a new stitch in the knitting after increasing the split. . Based on the above findings, the present inventors have completed the following method for preventing unraveling of the knitting yarn.

The present invention includes a first needle bed and a second needle bed opposed to each other in the front-rear direction, and a yarn feeder for supplying a knitting yarn, and the knitting needles provided on the first needle bed and the second needle bed have hooks. A knitting yarn for unwinding a knitting yarn surplus portion generated by switching a knitting yarn during the knitting of a knitted fabric using a flat knitting machine having a transfer blade on one side of the needle body Related to the method of preventing the release of This knitting yarn unclamping method is defined as follows when the side of the knitting needle where the blade is disposed is defined as the blade side and the side where the blade is not disposed is defined as the reverse blade side among the knitting width directions of the needle beds. Step A to Step C are provided.
-Step A of knitting the first stitch following the wale direction of the specific stitch at the switching position of the knitting yarn among the stitches of the existing knitted fabric portion locked to the first needle bed or the second needle bed.
A step B in which the first stitch is increased and the second stitch drawn from the first stitch is knitted. Here, the increase in the process B is performed by moving the yarn feeder from the reverse blade side toward the blade side.
A step C of fixing the second knitting stitch directly or indirectly to the first knitting to prevent the knitting yarn surplus portion from being released.

  As one form of the method for preventing unraveling of the knitting yarn of the present invention, in step C, the second stitch is overlapped with the first stitch, and the second stitch is knitted by knitting a continuous stitch in the wale direction of the overlapped stitch. Can be directly fixed to the first stitch.

  As one form of the method for preventing unraveling of the knitting yarn of the present invention, in step C, the third stitch that is continuous in the wale direction of the second stitch is knitted, the third stitch is overlapped with the first stitch, and the double stitch By knitting the stitches following the wale direction, the first stitch can be indirectly fixed to the second stitch.

  In a flat knitting machine having a knitting needle having transfer blades, the knitting needle hook of the first needle bed and the knitting needle hook of the second needle bed do not face each other directly. The opposing knitting needles of the second needle bed are arranged at positions shifted from the knitting needles of the first needle bed to the side where the blades of the knitting needles of the first needle bed are located. Therefore, when knitting the second stitch by splitting the first stitch, depending on whether the yarn feeder is moved to the blade side or the reverse blade side, the second stitcher loop with respect to the first stitcher loop The way of entanglement is different. In the method for preventing unraveling of the knitting yarn according to the present invention, contrary to the technique of Patent Document 1, the yarn feeder is moved from the reverse blade side toward the blade side to increase the first stitch, and the second stitch is increased. No sinker loops tie up the two sinker loops of the first episode. For this reason, even if a new stitch is formed after the increase, it is difficult for a large tension to act locally on the knitting yarn, so that it is possible to prevent the knitting yarn from being cut off during unwinding.

  Further, according to the knitting yarn unwinding prevention method of the present invention, the knitting yarn surplus portion can be firmly unwound. This is because a knot is formed at the surplus end portion of the knitting yarn, as shown in an embodiment to be described later, by performing the method for preventing unraveling of the knitting yarn of the present invention.

  The method for preventing the unraveling of the knitting yarn, in which the second stitch is directly fixed to the first stitch, is particularly suitable when inserting the yarn, and can finish the yarn insertion portion neatly.

  The method for preventing the unraveling of the knitting yarn, in which the second stitch is indirectly fixed to the first stitch, is particularly suitable when the yarn is discharged, and the yarn discharge portion can be finished finely.

FIG. 3 is a knitting process diagram of the knitting yarn release prevention method according to the first embodiment. FIG. 2 is a loop diagram in the vicinity of a knitting yarn surplus end portion that is unwound according to the knitting process diagram of FIG. 1. FIG. 5 is a knitting process diagram of a method for preventing knitting of a knitting yarn according to Embodiment 2.

<Embodiment 1>
In the first embodiment, based on the knitting process diagram of FIG. 1, the existing knitted fabric portion 10 knitted with the first knitting yarn Y1 fed from the first yarn feeder 8 is fed from the second yarn feeder 9. An example in which the second knitting yarn Y2 to be knitted is inserted will be described. For the first knitting yarn Y1 and the second knitting yarn Y2, knitting yarns of different colors and types can be used. In FIG. 1, “S + number” indicates the number of the knitting process, FB indicates the front needle bed, and BB indicates the rear needle bed.

  The knitting needle in FIG. 1 is a latch needle that opens and closes a hook provided at the tip of a needle body by swinging the latch, and a transfer blade is provided on one side surface of the needle body. Of the knitting width directions of FB and BB, the side where the blade of the latch needle is disposed is defined as a blade side D1, and the side where the blade is not disposed is defined as a reverse blade side D2. In the flat knitting machine of this example, the right side of the paper in FB is the blade side D1, the left side of the paper is the reverse blade side D2, and in BB, the left side of the paper is the blade side D1, and the right side of the paper is the reverse blade side D2.

  In S0, a state in which the existing knitted fabric portion 10 is knitted on the FB with the first knitting yarn Y1 fed from the first yarn feeder 8 is shown. From this state, yarn insertion is performed using the second yarn feeder 9 for feeding the second knitting yarn Y2.

  In S1, among the stitches of the existing knitted fabric part 10, the stitch switching position, that is, the stitch at the position where knitting with the second knitting yarn Y2 is started (fourth stitch from the left) is selected as the specific stitch 11. Following this specific stitch 11, knitting of a new knitted fabric portion starting in the wale direction of the existing knitted fabric portion 10 is started. First, the second yarn feeder 9 is moved to the right side (blade side D1 in the FB), and the first stitch 1 following the wale direction of the specific stitch 11 is knitted (step A). In the case of this example in which yarn insertion is performed, a portion extending from the first stitch 1 to the opposite side to the second yarn feeder 9 is the knitting yarn surplus end portion 5.

  In S2, the 1st stitch 1 latched by the knitting needle of FB is moved to the knitting needle of BB which counters. This S2 is performed in order to perform the knitting by moving the second yarn feeder 9 from the reverse blade side D2 with respect to the first stitch 1 during the knitting of the next S3.

  In S3, the second yarn feeder 9 is moved from the reverse blade side D2 to the blade side D1 on the left side of the sheet, that is, BB, and the first stitch 1 is increased (Step B). Specifically, while the first stitch 1 locked to the BB knitting needle is moved to the opposing FB knitting needle, the second knitting yarn Y2 is pulled out from the first stitch 1, and the first stitch 1 is locked. The second stitch 2 is knitted on the knitting needles of BB. By increasing the split while moving the second yarn feeder 9 from the reverse blade side D2 to the blade side D1, the two sinker loops 2a and 2b of the second stitch 2 are identified as shown in the loop diagram of FIG. The one side portion 11A that is the right side portion of the stitch 11 and the one side portion 1A of the first stitch 1 are crossed, but the other side portion 11B that is the left side portion of the specific stitch 11 and the first stitch 1 It does not cross the other side portion 1B. Therefore, a series of second knitting yarns Y2 extending from the second yarn feeder 9 to the first stitch 1 are easy to move, and it is difficult for local tension to be applied to the second knitting yarn Y2. Here, the one side portion 11A (1A) is a portion on the opposite side to the moving direction of the second yarn feeder 9 in S3 of FIG. 1 in the needle loop constituting the specific stitch 11 (first stitch 1). The other side portion 11B (1B) is a portion of the needle loop constituting the specific stitch 11 (first stitch 1) on the moving direction side of the second yarn feeder 9 in S3 of FIG.

  In S4, the second yarn feeder 9 is moved to the right side of the drawing, and the second yarn feeder 9 is stopped at a position on the right side of the first stitch 1 and the second stitch 2. In S5, the second stitch 2 locked to the BB knitting needle is overlapped with the first stitch 1 of the FB (part of the process C). The movement of the second yarn feeder 9 in S4 is a part of the second knitting yarn Y2 extending from the second yarn feeder 9 between the two stitches 1 and 2 when the first stitch 1 and the second stitch 2 are overlapped in S5. This is done to prevent pinching. By preventing a part of the second knitting yarn Y2 from being sandwiched between the first stitch 1 and the second stitch 2, the stitch surface is finished beautifully. By not performing S4, even if a part of the second knitting yarn Y2 is sandwiched between both stitches 1 and 2, the unraveling can be prevented.

  In S6, the knitting yarn surplus is obtained by knitting the stitch 4 continuous in the wale direction of the overlap of the first stitch 1 and the second stitch 2 and fixing the second stitch 2 directly to the first stitch 1. The end portion 5 is prevented from being unwound (the remaining portion of the process C). The moving direction of the second yarn feeder 9 when knitting the stitch 4 is not particularly limited. The reason why the stitch 4 is knitted by moving the second yarn feeder 9 to the left side (reverse blade side D2 in the FB) in S6 is that, as a result of performing S4, It is only because the double yarn feeder 9 was arranged. If S4 is not performed, the stitch 4 may be knitted by moving the second yarn feeder 9 to the right in S6.

  After S6, a new knitted fabric portion that continues in the wale direction of the existing knitted fabric portion 10 may be knitted. For example, the second yarn feeder 9 is moved to the left side, and a new knitted fabric portion following the wale direction of the existing knitted fabric portion 10 is knitted.

  FIG. 2 shows a loop diagram of the yarn insertion portion that has been unfastened by the above method. If the knitting yarn surplus end portion 5 is pulled in the direction of pulling out from the knitted fabric after the knitting is finished, the overlapping stitch of the first stitch 1 and the second stitch 2 is shrunk, and a knot is formed in the portion surrounded by the two-dot chain line, The knot is fixed between the specific stitch 11 and the stitch 4. By forming the knot, it is possible to suppress the unraveling of the knitting yarn excess end portion 5. Here, the two sinker loops 2a and 2b of the second stitch 2 cross only the one side portion 11A of the specific stitch 11 and the one side portion 1A of the first stitch 1, so that the knitting yarn excess end portion 5 is pulled. When forming the knot, the two sinker loops of the first stitch 1 are not fastened by the sinker loops 2a and 2b of the second stitch 2. Therefore, the second knitting yarn Y2 is easy to move from the knitting yarn surplus end 5 to the stitch 4, and the second knitting yarn Y2 is difficult to cut. Further, no knot is formed on the specific stitch 11, and the overlap of the first stitch 1 and the second stitch 2 becomes a knot, so that the surface of the specific stitch 11 is not disturbed, and the quality of the knitted fabric is not affected by the knot. Can be prevented from being damaged.

  The method for preventing unraveling of the knitting yarn described in the first embodiment is particularly suitable when inserting a yarn as illustrated in FIG. Since the double stitches of the first stitch 1 and the second stitch 2 are shrunk, the stitches 4 that follow the wale direction of the double stitches and the stitches of the new knitted fabric portion knitted in the course direction following the stitches 4 are wales. This is because the stitch row is almost aligned in the direction.

<Embodiment 2>
In the second embodiment, an example in which the first knitting yarn Y1 for knitting the existing knitted fabric portion 10 is extracted will be described based on the knitting process diagram of FIG. The way of viewing FIG. 3 is the same as that of FIG.

  In S1, the first yarn feeder 8 is moved to the right side of the drawing, and the final course of the existing knitted fabric portion 10 is knitted with the first knitting yarn Y1 (step A). In this case, the stitch knitted last in S1 is the first stitch 1, and the stitch of the existing knitted fabric portion 10 therebelow is the specific stitch 11.

  In S2, the 1st stitch 1 latched by the knitting needle of FB is moved to the knitting needle of BB which counters. In S3, the first yarn feeder 8 is moved toward the left side of the paper (blade side D1 in BB), the first stitch 1 is split and the second stitch pulled out from the first stitch 1 is obtained. 2 is knitted (step B). Also in this case, as in the first embodiment, the two sinker loops of the second stitch 2 cross only one side portion (the right side portion of the paper) of the specific stitch 11 and one side portion of the first stitch 1. The two sinker loops of the first stitch 1 are not tightened by the sinker loop of the second stitch 2. Therefore, a series of first knitting yarns Y1 extending from the first yarn feeder 8 to the first stitch 1 are easy to move, and it is difficult to apply a large local tension to the first knitting yarn Y1.

  In S4, the first yarn feeder 8 is moved to the right side, and the third stitch 3 continuous in the wale direction of the second stitch 2 is knitted (part of step C). The third stitch 3 is the last stitch knitted with the first knitting yarn Y1. Therefore, the portion extending from the third stitch 3 to the first yarn feeder 8 becomes the knitting yarn surplus end portion 5. By knitting the third stitch 3, the second stitch 2 is confirmed.

  In S5, the first yarn feeder 8 is moved to the left, and the third stitch 3 is a twisted stitch. By setting the third stitch 3 to be a twisted stitch, the sinker loops of the third stitch 3 intersect each other, and a frictional force is generated between the two sinker loops, so that the knitting yarn surplus portion 5 is difficult to unravel. However, even if the third stitch 3 is not twisted, the knitting yarn surplus portion 5 can be prevented from unraveling, so S5 need not be performed.

  In S6, the third stitch 3 is overlapped with the first stitch 1 as shown by the thick arrow (a part of the process C). After S6, a new knitted fabric portion continuous in the wale direction of the existing knitted fabric portion 10 knitted with the first knitting yarn Y1 is knitted using the second knitting yarn fed from a second yarn feeder (not shown). To do. At that time, the stitch following the wale direction of the overlap of the first stitch 1 and the third stitch 3 shown in S6 is knitted with the second knitting yarn, and the first stitch 1 and the second stitch 2 are the third stitch. 3 is indirectly fixed (the rest of the process C).

  When the knitting yarn surplus end 5 is pulled in the direction of pulling out from the knitted fabric after knitting, the second stitch 2 and the third stitch 3 and the second side crossing the one side portion (the right side portion of the paper) of the specific stitch 11 are obtained. The two sinker loops of stitch 2 shrink. As a result, also by the knitting yarn unwinding prevention method of this example, a knot is formed at the knitting yarn surplus end portion 5 as in the first embodiment, and the knitting yarn surplus end portion 5 is unwound by the knot.

  The method for preventing the unraveling of the knitting yarn that indirectly fixes the second stitch 2 to the first stitch 1 via the third stitch 3 shown in the present embodiment is particularly suitable when performing threading as illustrated in FIG. It is. As shown in S6, when the knitted fabric is viewed from the front side, that is, when the knitted fabric is viewed from the back side to the near side, the third stitch 3 is overlapped on the back side of the first stitch 1, This is because the third stitch 3 and the second stitch 2 are difficult to see from the front side of the knitted fabric.

<Other embodiments>
With the knitting yarn release prevention method described in the first embodiment, the knitting yarn surplus portion at the yarn take-out portion can also be released. In addition, the knitting yarn unwinding method described in the second embodiment can also be used to prevent the knitting yarn surplus portion at the yarn insertion portion from unwinding.

  In the knitting yarn release prevention method of the present embodiment, when performing a split increase on the first stitch, the yarn feeder is moved from the reverse blade side of the knitting needle to which the first stitch is locked toward the blade side to increase the split. There is no limitation on the moving direction of the yarn feeder when the first stitch is knitted. For example, in S1 of FIG. 1, the second yarn feeder 9 is moved to the left side of the page, and the first stitch 1 is knitted on the FB knitting needle. Then, without moving the first stitch 1 of the knitting needle of the FB to the opposing BB, the second yarn feeder 9 is moved to the right side of the drawing to increase the first stitch 1 to form the second stitch 2. . In this case, the second yarn feeder 9 is moved from the reverse blade side D2 to the blade side D1 in the FB, and the first stitch 1 is increased.

  In addition, in the knitting yarn release prevention method of the present embodiment, a flat knitting machine including a latch needle is used. However, the knitting yarn release prevention method includes a knitting needle having transfer blades, for example, a compound needle. It can also be performed using a flat knitting machine. The flat knitting machine to be used may be a four-bed flat knitting machine.
