Description

  The present invention relates to a knitting yarn fixing method for fixing a knitting yarn to a base stitch row locked to a needle bed when knitting a knitted fabric using a flat knitting machine.

  In a knitted fabric having a horizontal stripe pattern or the like, 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 fixing method (knitting yarn unclamping method) that causes the flat knitting machine to perform the unclamping (see, for example, Patent Document 1).

  In the fixing method described in Patent Document 1, first, the yarn feeder is moved from the state where the base stitch row is locked to the needle bed, and the number of the specific stitches in the base stitch row locked to the needle bed is increased. A first new stitch is formed. Then, the second new stitch is formed with respect to the first new stitch, and the two new sinker loops are intersected with one sinker loop of the specific stitch, so that the knitting yarn is entangled with the specific stitch. Fix it.

Japanese Patent Laying-Open No. 2015-17352

  In the knitting yarn fixing method of Patent Document 1, the yarn feeder must be kicked back several times, and the stitches must be transferred several times between the kickbacks. Therefore, when there are a large number of knitting yarn fixing portions in one knitted fabric, the time until the knitted fabric is completed becomes long. In recent years, with the diversification of consumer needs, there has been a demand for rapid supply of knitted fabrics, so there is a need to develop a knitting yarn fixing method that can efficiently fix knitting yarn to a base stitch row. .

  The present invention has been made in view of the above circumstances, and one of its purposes is to provide a knitting yarn fixing method capable of efficiently fixing a knitting yarn to a base stitch row.

The method for fixing a knitting yarn according to the present invention uses a flat knitting machine having one needle bed facing forward and backward and the other needle bed, from the state in which the base stitch row is locked to one needle bed to the needle bed. A knitting yarn fixing method for supplying knitting yarn and fixing the knitting yarn to the base stitch row, comprising the following steps.
[Step I] ... Using the knitting yarn, a pair of retaining stitches are continuously knitted to a pair of specific stitches that are part of the base stitch row and adjacent in the knitting width direction, and the specific stitches A crease is formed in the empty needle in the vicinity of.
[Step II]... Both stitches are overlapped to form a double stitch, and the additional stitch is transferred to a position where a hole formed in the base stitch row is filled in the process of forming the double stitch.
[Step III] ... A new base stitch row including the fixed stitch that continues in the wale direction of the double stitches and the additional stitches is knitted.

  Here, the additional stitches are for filling the holes formed in the base stitch row in the process of forming the double stitches, so they are not formed at positions far away from the specific stitches. It is preferable that the position where the additional stitch is formed is not more than three stitches away from the specific stitch in the knitting width direction. May be appropriately determined.

  As one form of the fixing method of the knitting yarn of this invention, the form which uses one side as a back stitch and the other is a front stitch among the pair of said fastening stitches can be mentioned.

  As one form of the knitting yarn fixing method of the present invention, the additional stitch can be formed by splitting one of the pair of specific stitches. Here, the split increase refers to a knitting operation in which the stitch P locked to the knitting needle X is transferred to the knitting needle Y facing the knitting needle X, and a new stitch Q pulled out from the stitch P is formed on the knitting needle X. (For example, see Japanese Patent No. 2604653). In this case, the stitch P transferred to the knitting needle Y becomes an additional stitch.

  As one form of the knitting yarn fixing method of the present invention, there can be mentioned a form in which the knitting yarn is fixed to a plurality of fixing portions having different knitting width directions in the base stitch row. In that case, all the knitting operations provided in the step I are performed on the same knitting course for all the fixed portions, and each knitting operation provided in the step II is the same for all the fixed portions. Performed in the organization course. The knitting operation of the process I is the knitting of the pair of fastening stitches and the knitting of the additional stitches. Further, the knitting operation in the step II is a transfer for forming the double stitches and a transfer of the additional stitches.

  As one form of the knitting yarn fixing method of the present invention, there can be mentioned a form in which shrink yarn is used for either the base knitting yarn constituting the base stitch row or the knitting yarn. Examples of the shrink yarn include a heat shrink yarn and an elastic yarn.

  In the knitting yarn fixing method according to the present invention, the knitting yarn is firmly fixed to the base stitch row only by knitting a pair of retaining stitches, overlapping both retaining stitches, and knitting a new stitch on the overlapping stitch. The knitting efficiency is superior to that of the prior art. In the knitting yarn fixing method of the present invention, holes formed by forming double stitches when fixing the knitting yarn can be filled with additional stitches, and the formation of holes in the knitted fabric can be suppressed.

  By knitting the front stitch and the back stitch, it is possible to increase the length of the connecting yarn connecting both the stitches as compared to the case where the both stitches are only the front stitch or only the back stitch. Thus, yarn breakage at the time of transferring the stitches and forming the double stitches can be suppressed. In addition, as shown in FIG. 2 of the embodiment described later, in the process in which the both-fastening stitches are deformed and the knitting yarn is entangled with the base stitch row, if the connecting yarn connecting the both fastening stitches is long, the both-fastening stitches are easily deformed. The knitting yarn is easily entangled with the base stitch row.

  By using a split increase for forming the additional stitches, the additional stitches are formed simultaneously with the knitting of the fastened stitches, so that the knitting efficiency of the knitted fabric can be improved.

  When there are a plurality of knitting yarn fixing portions in one base stitch row, in the conventional knitting yarn fixing method, one fixing portion must be processed and then another fixing portion must be processed sequentially. On the other hand, in the knitted fabric fixing method of the present invention, it is possible to process all the fixing points in a lump. Therefore, the knitting yarn fixing method of the present invention can fix the knitting yarn to the base stitch row much more efficiently than the conventional knitting yarn fixing method.

  An unprecedented three-dimensional knitted fabric can be knitted by using the base knitting yarn or the knitting yarn fixed to the base stitch row as the shrink yarn. For example, if the base stitch row is composed of shrink yarns, a knitted fabric having pile-shaped knitting yarns can be knitted as shown in FIG. If the inlay wire is made of shrink yarn when inlay knitting is performed, a three-dimensional knitted fabric having a hook shape can be knitted as shown in FIG.

FIG. 3 is a knitting process diagram according to the fixing method of the knitting yarn of the first embodiment. FIG. 3 is a loop diagram illustrating a state of a knitting yarn fixed by the knitting yarn fixing method according to the first embodiment. (A) is a photograph of a knitted fabric in which a pattern is formed with an inlay wire, and (B) is a photograph showing a photograph of a knitted fabric in which a brushed inlay wire is formed. (A) is a photograph of a knitted fabric in which a pile-shaped inlay wire is formed, and (B) is a diagram showing a photograph of a three-dimensional knitted fabric having a hook shape.

<Embodiment 1>
As one of means for forming a pattern on the knitted fabric, the stitches of the base stitch row constituting the knitted fabric are distributed to the front and back needle beds, and the base knitting yarn constituting the base stitch row is arranged between the distributed stitches. An inlay knitting in which a different knitting yarn (inlay wire) is inserted is known (for example, Japanese Patent Application Laid-Open No. 2007-277738). In the inlay knitting, a pattern is formed by an exposed portion formed by exposing the inlay wire to the surface of the base stitch row. However, in a tubular knitted fabric such as a sweater, it is difficult to form a pattern by inlay knitting. Since the inlay wire is only inserted between the stitches of the base stitch row, if any part of the inlay wire breaks, there is a risk that the inlay wire will be chained off the base stitch row. It is. In order to solve such problems, both ends of the exposed portion may be individually fixed to the base stitch row, but it takes an enormous amount of time to fix a large number of exposed portions by the conventional method of fixing a knitting yarn. Will be applied. Therefore, fixing the exposed portion of the inlay wire by the knitting yarn fixing method of the present invention improves the efficiency of fixing the exposed portion. Hereinafter, an example of the knitting yarn fixing method of the present invention will be described based on the knitting process diagram of FIG.

  In the present embodiment, a lower front needle bed (hereinafter referred to as FD) and a lower rear needle bed (hereinafter referred to as BD) that extend in the left-right direction and face each other in the front-rear direction, and are provided above these FD and BD, A four-bed flat knitting machine having an upper front needle bed (hereinafter referred to as FU) and an upper rear needle bed (hereinafter referred to as BU) in which a large number of knitting needles are arranged at the same pitch as that of the needle bed is used. In the flat knitting machine, stitches can be transferred between the front and back needle beds, and the BD and BU provided in the flat knitting machine can be racked left and right.

  “S + number” in the left column of FIG. 1 indicates the number of the knitting step, and the right column indicates the knitting state of the needle bed in each knitting step. The capital letter in the right column indicates the position of the knitting needle, and the arrow indicates the direction of transfer. The pentagonal mark indicates a yarn feeder 80 that feeds the base knitting yarn Y8 and a yarn feeder 90 that feeds the inlay wire Y9.

  In S1, the base knitting yarn Y8 is fed from the state in which the front knitted fabric portion and the rear knitted fabric portion of the tubular knitted fabric are locked to the knitting needles A to L of the FD and the knitting needles A to L of the BD, respectively. The yarn feeder 80 to be moved is moved to the right side of the drawing, and the base stitch row 10 (rear knitted fabric portion) is knitted. In the base stitch row 10, the stitches of the knitting needles C and D (I, J) of the BD are the specific stitches 1 and 2 in the knitting yarn fixing method of the present invention, and are adjacent in the knitting width direction.

  In S2, the yarn feeder 80 is moved leftward to knitting the front knitted fabric portion by one stage, and the knitting needles C, F, G, H, I, and L of the BD are knitted needles C, F, and G of the FU. , H, I, L. This stitch transfer is preparation for placing and fixing the inlay wire Y9 (see S3) to the base stitch row 10. The reason for transferring the specific stitch 1 is to knit the back stitch (see the fastening stitch 3 in S3) in the wale direction of the specific stitch 1. If the stop stitch 3 is a front stitch, the transfer of the specific stitch 1 is not necessary.

  In S3, the yarn feeder 90 for supplying the inlay wire Y9 is moved in the right direction, the stitch 3 is knitted on the knitting needle C (I) of the FU, and the knitting needle D (J) of the BD is increased (the present invention). Step I)). By performing the additional increase with the knitting needle D (J) of the BD, the specific stitch 2 locked to the knitting needle D (J) of the BD in S2 is transferred to the knitting needle D (J) of the FU and the specific stitch The fastening stitch 4, which is a new stitch pulled out from 2, is engaged with the knitting needle D (J) of the BD. The fastening stitches 3 and 4 are a pair of stitches that are continuously knitted by a single movement of the yarn feeder 90, and the fastening stitch 3 and the fastening stitch 4 are directly connected via a sinker loop. In addition, the specific stitch 2 transferred to the FU due to the additional increase is used as an additional stitch 5 in a subsequent process. That is, in S3, the knitting of the pair of retaining stitches 3 and 4 and the knitting of the additional stitch 5 are performed on the same knitting course for all of the plurality of fixed portions.

  Here, the additional stitch 5 can also be formed by increasing the number of the specific stitch 1. Further, the additional stitch 5 may be a hook formed on the empty needle. For example, a hook (increase 5) is formed on the knitting needle D (J) of the FU facing the specific stitch 2 of S2 or the knitting needle E (K) adjacent thereto. Alternatively, a stitch (increase) 5 may be formed on the knitting needle C (I) of the BD facing the specific stitch 1 of S2, the knitting needle B of the FU (BD knitting needle H), or the like.

  In S4, in the same knitting course, the additional stitch 5 locked to the knitting needle D (J) of the FU is transferred to the knitting needle C (I) of the BD (part of the process II). This transfer is an operation performed to fill the holes formed in the base stitch row 10 by reducing the number of stitches in the knitting width direction of the base stitch row 10 as the double stitches 7 are formed in the next S5. That is, in S4, among the BD knitting needles C and D (I, J) in which the specific stitches 1 and 2 are locked in S1, the BD knitting needle C ( Transfer the eye 5 to I).

  In S5, on the same knitting course, the stitches 3 formed on the knitting needles C (I) of the FU in S3 and the stitches 4 formed on the knitting needles D (J) of the BD by increasing the number are overlapped, and the BD A double stitch 7 is formed on the knitting needle D (J) (part of Step II).

  In S6, the stitches of the knitting needles F, G, H, and L of the FU are transferred to the knitting needles F, G, H, and L of the BD. By this S6, the inlay wire Y9 is inserted between the stitches of the base stitch row 10.

  In S7, the yarn feeder 80 is moved rightward, and a new base stitch row 11 is knitted on the knitting needles A to L of the BD (corresponding to step III of the present invention). The base stitch row 11 includes fixed stitches 8 and 9 continuing in the wale direction of the double stitch 7 and the additional stitch 5 in S6, and the inlay wire Y9 arranged in the base stitch row 10 is formed by the base stitch row 11. Fixed.

  In the knitting process described above, as shown in S3, the fastening stitches 3, 4 and the additional stitch 5 are formed on the same knitting course at the two fixed locations of the inlay wire Y9. Further, as shown in S4, the transfer of the additional stitches 5 at the two fixed points is performed in the same knitting course, and the stitches of the stitches 3 for forming the double stitches 7 at the two fixed points as shown in S5. The transfer is performed on the same organization course. Therefore, according to the knitting configuration, the inlay wire Y9 can be fixed to the base stitch row 10 more efficiently than in the conventional configuration in which the knitting yarn is sequentially fixed at each fixing point.

  After S7, when the inlay wire Y9 is arranged on the front knitted fabric portion locked to the FD, the FD is regarded as one needle bed in the present invention, and the same knitting as S1 to S7 is performed using the FD and BU. Just do it. Further, when the inlay wire Y9 is arranged and fixed on the base stitch row 11, the base stitch row 11 may be regarded as the base stitch row 10 of S1, and S2 to S6 may be performed.

  Next, the mechanism by which the inlay wire Y9 is firmly fixed to the base stitch row 10 by performing the knitting step will be described based on the loop diagram of FIG. The loop diagram of FIG. 2 is a loop diagram in which the rear knitted fabric portion locked to the BD of S7 in FIG. 1 is viewed from the outside of the cylinder, and the rear knitted fabric from FIG. 2 (A) to (D). The change with time of the stitches in the part is shown.

  When the inlay wire Y9 is pulled to the left and right from the state shown in FIG. 2A, the fastening stitches 3 and 4 are deformed so as to become one as shown in FIGS. 2B and 2C. The fastening stitches 3 and 4 are overlapped stitches 7 and are fixed by the fixing stitches 8 following the stitches 7, so that the fastening stitches 3 and 4 cannot be integrated into the inlay. The wire Y9 is wound around the base of the fixed stitch 8 (position of the sinker loop). Further, with the deformation of the fastening stitches 3 and 4, the specific stitch 1 is deformed in a direction approaching the fixed stitch 8, and the inlay wire Y 9 is fixed to the base stitch row 10.

  Further, as shown in FIG. 2D, the additional stitch 5 is disposed at a position where the hole of the base stitch row 10 is filled, and the increased stitch 5 suppresses the formation of a hole in the knitted fabric.

  If the above-described knitting yarn fixing method is used, for example, a knitted fabric such as a sweater having an inlay pattern as shown in FIG. 3A can be knitted. The white portion forming the handle in FIG. 3A is an exposed portion where the inlay wire is exposed on the front side of the knitted fabric (such as a portion crossing the knitting needles E to I of BD in S6 in FIG. 1). If both ends of each exposed part are firmly fixed by the above-described method of fixing the knitting yarn, even if one exposed part is cut, the other exposed part is not affected, and the inlay wire is made of the base stitch. It is never pulled from the queue. Therefore, it is possible to provide a tubular knitted fabric in which various patterns are formed using the inlay wire.

  If it is the structure which fixes the exposed part of an inlay wire separately, an exposed part can also be dared to cut | disconnect. As a result, as shown in FIG. 3B, a knitted fabric in which the inlay wire (see the white portion) is raised can be obtained. Since both ends of the exposed portion are securely fixed to the base stitch row, such a knitted fabric can be produced because the inlay wire does not come off the base stitch row even if the exposed portion is cut.

  Also, if the base stitch row is knitted with heat shrinkable yarn and the inlay wire is made non-heat shrinkable yarn and the finished knitted fabric is heat treated, when the base stitch row shrinks, the inlay wire that has not shrunk into a pile shape Protruding. As a result, as shown in FIG. 4A, a knitted fabric having an exposed portion (see the curved black portion) in a pile shape can be produced.

  Further, when the base stitch row is knitted with the non-heat-shrinkable yarn, the inlay wire is used as the heat-shrinkable yarn, and the finished knitted fabric is heat-treated, when the inlay wire is contracted, the base stitch row is pulled by the inlay wire. As a result, as shown in FIG. 4B, a three-dimensional knitted fabric with ridge-like irregularities can be produced.

<Modification>
Instead of inserting the knitting yarn Y9 between the front and rear stitches of the base stitch row 10 as in the first embodiment, the knitting yarn Y9 is placed along one side or the other side of the base stitch row 10, and the knitting yarn is provided. Y9 may be fixed to a plurality of fixing points in the base stitch row 10. For example, if the knitting yarn Y9 is fixed by performing the same knitting as S3 to S5 without transferring the stitches of the knitting needles F, G, H, and L in S2 of FIG. Arranged inside the knitted fabric. If the knitting yarn Y9 is a knitting yarn that is difficult to stretch, a tubular knitted fabric in which the elongation in the knitting width direction is suppressed by the knitting yarn Y9 is obtained.

<Embodiment 2>
The method for fixing a knitting yarn according to the first embodiment can also be used for preventing the knitting yarn from being unwound at the time of yarn insertion and yarn removal. For example, when a sweater with a horizontal stripe pattern is knitted, another knitted fabric portion is formed with a second knitting yarn having a different color from the first knitting yarn, in the wale direction of the knitted fabric portion knitted with the first knitting yarn. Organize. At that time, the first knitting yarn is taken out and the second knitting yarn is put into the yarn. If the knitting yarn fixing method of Embodiment 1 is used to fix the remaining end portions of these knitting yarns, the remaining end portions can be firmly fixed. In addition, the knitting yarn fixing method of Embodiment 1 can also be used for fixing an intarsia pattern knitting yarn.
