Description

The present invention relates to a knitting method for a knitted fabric having an end region by a flat knitting machine and a knitted fabric having an end region obtained by the knitting.

In the flat knitting machine, a stitch row in the course direction is sequentially knitted in the wale direction to form a knitted fabric product. The final stitch row of the knitted fabric product in the wale direction is subjected to bind-off processing to prevent loosening.

For example, Patent Document 1 describes that the final stitch rows in the wale direction such as a knitted fabric that is knitted in a tubular shape with front and rear needle beds are sequentially connected in the course direction by bind-off processing. It is also described that the last stitch of the bind-off stitch is knitted to prevent runback. Since the stitches to be knitted to prevent run-back remain in a string shape, it is necessary to manually end the yarn after knitting (Fig. 2 of Patent Document 1 and page 3, column 6, line 33 to line 38 of specification 3). See line).

Patent Document 2 describes performing a bind-off process for forming a belt-like shape in a plurality of stages on the end portion of the tubular knitted fabric in the wale direction. The bind-off process proceeds while holding the starting point, and finally the end point can be joined to the starting point. A knitting for runback prevention is required for the joint between the starting point and the ending point, as in Patent Document 1.

Japanese Patent No. 2747914 JP, 2012-180616, A

In the bind-off process for the final stitch row in the wale direction, even if it is possible to prevent unraveling, if the final stitch after the bind-off process is removed from the knitting needle, there is a risk that run-out will start from the removed stitch and unraveling will start. is there. In order to prevent this loosening, knitting is performed for about 20 courses in the wale direction with a width of 1 to 3 stitches to form a string-like knitted fabric. Even if the string-shaped knitted fabric is unraveled, the knitted fabric product is not unraveled.

However, although the string-like knitted fabric is not necessary for the knitted fabric product, it will protrude from the knitted fabric. Since such protrusions reduce the commercial value of the knitted fabric product, it is necessary to prevent loosening and to flatten the protrusions to improve the finish in a manual post-process.

An object of the present invention is to provide a knitting method for a knitted fabric having a termination region and a knitted fabric having the termination region for improving finish of bind-off processing of the final end in the wale direction of the knitted fabric, and reducing the trouble of a post-process. is there.

The present invention uses a flat knitting machine having at least a pair of front and rear needle beds, and in a knitting method of a knitted fabric having an end region for unraveling in a wale direction final stitch row of a knitted fabric by bind-off processing
The end region is divided into one side and the other side in the knitting width direction with a dividing line, and the direction facing one side from the dividing line is one direction and the direction facing the other side is the other direction.

FIG. 2 is a knitting process chart showing a schematic procedure for the first half of the process D of FIG. FIG. 3 is a knitting process diagram showing a schematic procedure for the latter half of the process D of FIG. FIG. 4 is an enlarged photograph showing the inside of the tubular knitted fabric 1 having the end region 3 knitted by the knitting method of FIG. FIG. 5 is an enlarged photograph showing the outer side of the tubular knitted fabric 1 having the end region 3 knitted by the knitting method of FIG.

1 to 5, a knitting method of a knitted fabric having an end region and a knitted fabric having an end region will be described as an embodiment of the present invention. For convenience of description, parts not described in the drawings to be described may be referred to with reference signs described in other drawings.

FIG. 1 schematically shows a method of knitting the termination region 3 as an embodiment of the present invention. The terminal region 3 is a two-bed flat knitting machine having at least a pair of front needle beds FB (hereinafter referred to as FB) and rear needle beds BB (hereinafter referred to as BB) that face each other in the front-rear direction, and is a tubular knitting machine. It is formed on the terminal side in the wale direction of the base knitted fabric 2 which is the main part of the fabric 1. The stitch row formed in FB and BB is shown by a straight line. Transfer can be performed between the FBs and BBs facing each other, and racking for shifting the relative position between the FBs and BBs is also possible. As the knitting needle, for example, a compound needle as described in Japanese Patent No. 2946325 is used, and a knitting needle capable of holding a stitch temporarily to a knitting needle that holds another stitch is used. However, in the following description of the knitting method, even in the case of knitting using both FB and BB needle beds such as rib knitting, a stitch row is formed on the needle bed for knitting the front stitch. .. The formation of the stitch row is simplified and only the result is shown. When the holding is not used or is not available, the needle pull-out knitting may be performed in which every other stitch is locked to the knitting needle to prepare an empty needle. If a four-bed flat knitting machine is used, knitting is possible without preparing empty needles.

The base knitted fabric 2 knits a tubular knitted fabric by alternately knitting with FB and BB while supplying the knitting yarn from the same yarn feeder 4. The left side and the right side of the dividing line (SL) in the figure are defined as one side and the other side, respectively. The knitting method of this embodiment includes the following steps A, B, C, and D.

The end region 3 is a so-called C-shape in which the base knitted fabric 2 is lap-knitted, and then the process A and the process B are alternately knitted, and knitting of the knitted fabric held on the BB is repeated between the processes. Form by knitting. Specifically, the knitting row 3Bc of the BB is knitted in the other direction after the knitting row 3Rc on one side of the FB starts knitting in the other direction (rightward in the drawing) and folds back. Subsequently, the knitting sequence 3Lc on the other side of the FB starts knitting in one direction (to the left in the drawing) and folds back to form a reciprocal knitting, and then knitting the knitting sequence 3Bc of the BB in one direction is repeated. Hereinafter, each step will be described.

In the process A, the terminating region 3 for preventing the final stitch row in the wale direction of the knitted fabric 1 from being unraveled is divided into one side and the other side in the knitting width direction by the division line SL, and the stitch row 3Rc on one side is divided into the division line SL. Move it in the direction away from and provide an empty needle. The stitch row 3Rc locked by the FB on one side is temporarily transferred to the BB, the BB is racked, and the stitch row 3Rc is returned to the FB in a state of being relatively moved by one pitch (1P) in one direction, An empty needle is provided on the section line SL side. Similarly, new widening stitches a, b, c, d are sequentially formed on the empty needle, and knitting is performed on the stitch row moved in one direction to form a new stitch row 3Rc continuing in the wale direction. ..

In this embodiment, the first course stitch row 3Rc in the end region 3 following the base knitted fabric 2 is formed by feeding the knitting yarn from the yarn feeder 4 from the knitting end on one side toward the division line SL. To do. The stitch row 3Rc locked by the knitting needle on one side is moved in one direction by one pitch to provide an empty needle. The stitches adjacent to the empty needle are split and increased to form a new widening stitch a on the empty needle. Next, the yarn feeder 4 is folded back and moved in one direction from the division line SL to form a stitch course 3Rc of the second course following the stitch row 3Rc of the first course, and then the stitch row 3Rc is the same as that of the first course. And move it in one direction to provide an empty needle between it and the widening stitch a. The vacant needle is split and increased with respect to the stitches adjacent to the vacant needle in the moved stitch row 3Rc of the second course, and a new stitch b is formed on the vacant needle. It should be noted that the new widening stitches a and b can also be formed by multiplying stitches instead of split stitching.

When the stitch row 3Rc is reciprocally knitted in the FB, a new stitch is knitted by moving the yarn feeder 4 in the other direction with respect to the stitch of the base knitted fabric 2 held on the BB. Since the stitch row 3Rc of the FB is displaced in one direction, a stitch shift occurs between the FB and the BB. However, it is sufficient to perform the wrap-around knitting for shifting the stitch at the left end portion of the FB to the BB. This knitting is also applied to the shift between the stitch row 3Lc of the FB and the BB.

In the next step B, the stitch row 3Lc is formed on the other side of the FB in the same manner as the step A on the one side. The stitch row 3Lc formed on the other side of the division line SL is moved in the other direction away from the division line SL to provide an empty needle on the division line SL side. The stitches adjacent to the empty needle are split and increased, new new stitches α, β, γ, δ are formed on the empty needle, and a new stitch row 3Lc that follows the wale direction of the stitch row moved in the other direction is formed. ..

In the present embodiment, the process A and the process B are alternately repeated in a C-shaped knitting pattern in the vicinity of both sides of the section line SL until the course for the wale direction forming the end region 3 is obtained. Repeating the formation of the stitch rows 3Rc, 3Lc so as to be connected by the stitch row 3Bc knitted by the BB, widening stitches a, b, c, d; α, β, γ, δ are formed on both sides of the dividing line SL. In addition, the knitted fabrics 3R and 3L are also formed.

In the process C, the knitted fabric 1 is subjected to a bind-off process for the final wale stitch row to form a course bind-off portion 3C. The stitch rows 3Rc, 3Bc, 3Lc locked to the knitting needles of FB and BB are the final stitch rows of the knitted fabric 1 in the wale direction. When the moving distance of the stitch rows 3Rc and 3Lc locked by FB from the partition line SL becomes large, the knitting yarns connected to the stitch row 3Bc locked by BB at the ends of the knitting width are extended, It is preferable to perform the twist knitting as described above.

In this embodiment, the end of the one side stitch row 3Rc on the parting line SL side is set as the first stitch 3Cs of the course bind off portion 3C, and the bind off process proceeds in one direction. When the bind-off processing of the stitch row 3Rc of the FB is completed, the bind-off processing is performed in the other direction on the stitch row 3Bc of the BB, and subsequently the bind-off processing is also performed in one direction on the stitch row 3Lc of the FB. The stitch adjacent to the widening stitch δ in the stitch row 3Lc is the last stitch 3Ce of the course bind-off portion 3C. Except for the stitch 3Ce, the stitches that follow the stitch rows 3Rc, 3Bc, 3Lc in the wale direction are removed from the knitting needle by the bind-off process, so the movements of the widening stitches a, b, c, d; It will be easier.

In the process D, the stitches in the forming order of the widening stitches a, b, c, d; α, β, γ, δ formed on one side and the other side with the section line SL as a boundary are overlapped. As described above, the binding process is performed between the FB and BB, and the bind-off process is performed in the reverse order of the formation order. By this bind-off processing, the knitted fabric 3R formed by the one side stitch row 3Rc and the knitted fabric 3L formed by the other side stitch row 3Lc are joined, and the wale bind-off portion 3W is formed at the joined portion. Step D is performed as described below.

FIG. 2 shows the general procedure for the first half of step D of FIG. 1 at D0 through D4. Step D0 shows the end state of step C in FIG. 1, and in FB, widening stitches a, b, c, d; α, β, γ, δ are formed on both sides of the dividing line SL, and the widening stitch δ is in the other direction. The last stitch 3Ce of the course bind-off portion 3C is locked to the knitting needle adjacent to. From the yarn feeder 4, the knitting yarn following the last stitch 3Ce of the course bindoff portion 3C is supplied. In the next step D1, the widening stitches a, b, c, d on one side are transferred to BB. In the next step D2, BB is moved by 1 pitch (1P) in the other direction with respect to FB, the widening stitch a is transferred to FB, and the double stitching is formed by overlapping with the widening stitch α locked by FB. To do. In the next step D3, BB is further moved in the other direction by 2 pitches (2P) with respect to FB, the widening stitch b is transferred to FB, and the double stitching is overlapped with the widening stitch β locked by FB. To form. Similarly, by the process D4, the widening stitches γ and δ locked by the FB are also overlapped with the widening stitches c and d to form a double stitch.

In the above description, all of the widening stitches a, b, c, and d are once transferred to BB in the step D1, and then transferred one by one to the FB in the following steps to be overlapped. Further, in order to provide overlapping stitches in the order of formation, the stitches are moved to the BB one by one in the order of the widening stitches d, c, b, and a so as to face the widening stitches α, β, γ, δ of the FB, respectively. You may make it pile up at once after arrange|positioning.

FIG. 3 shows a schematic procedure of the latter half of the process D of FIG. 1 from D5 to D9. In step D5, the last stitch 3Ce of the course bind-off portion 3C is further overlapped with the overlap stitches δ and d formed in step D4 of FIG. 2 to form a third overlap stitch. In step D6, a new stitch is formed on the third stitch. This stitch becomes the first stitch 3Ws of the wale bind-off portion 3W. In step D7, the new stitch is further overlapped with the double stitches γ and c to form a third double stitch. In step D8, a new stitch is formed on the third stitch. Thereafter, in the same manner, the final third stitch is formed by the step D9, and a new stitch is formed for the third stitch in the step D9. This new stitch is formed as the last stitch 3We of the wale bind-off portion 3W at the position of the stitch row preceding the final stitch row in the wale direction by a plurality of courses. Even if a string-like knitted fabric is added to the last stitch 3We to prevent runback, the flat finish of the final stitch row in the wale direction of the knitted fabric 1 is not hindered, and the work of the subsequent process is reduced. You can enable it.

Although the widening stitches a, b, c, d; α, β, γ, δ are formed by four stitches on both sides of the dividing line SL, other numbers may be used. If the number of widening stitches is large, the position where the last stitch 3We of the wale bind-off portion 3W is formed can be separated from the final end of the wale. If the number of courses in the end region 3 is combined with the collar length, the position of the last stitch 3We becomes the boundary with the body, so that it is difficult to stand out.

4 and 5 show enlarged examples of the inside and outside of the tubular knitted fabric 1 having the end region 3 knitted by the knitting method of FIG. 1, respectively. The knitted fabric 1 is knitwear, the end region 3 is a collar portion formed by rib knitting, and the final stitch row in the wale direction is bind-off processed. The end region 3 has a plurality of courses formed prior to the final stitch row in the wale direction, and is provided with the knitted fabrics 3R and 3L on both sides which are sectioned by the section line SL in the middle in the course direction. The bind-off process is performed by the wale bind-off part 3W and the course bind-off part 3C. The wale bind-off portion 3W joins the knitted fabrics 3R and 3L on both sides by bind-off processing from the final stitch row in the wale direction toward the starting end side of the end region 3. The course bind-off portion 3C is applied to the final stitch row in the wale direction, and the bind-off treatment in the course direction 3Cd is performed so as to follow the wale bind-off portion 3W. This is formed before the wale bind off portion 3W. Since the final stitch 3We of the bind-off process does not remain in the final stitch row in the wale direction, it becomes flat and the finish can be improved. The last stitch of the bind-off process is formed at the position of the stitch row on the starting end side of the multi-course end region 3 with respect to the final stitch row in the wale direction, and further inside the tubular knitted fabric. Even if the knitted fabric 5 is added, the finish of the course bind-off portion 3C is not hindered, and it is possible to reduce the trouble of the post-process. In this embodiment, a loosening stopper 6 is added to the end of the cord-shaped knitted fabric 5 with a highly elastic yarn. In addition, since the bind-off process is completed at an inconspicuous place, a simple unraveling process can be performed, which makes it possible to reduce the trouble of the post-process.

Although the knitted fabric 1 of this embodiment is a tubular knitted fabric, it may be a C-shaped knitted fabric having an opening. For example, the present embodiment may be applied to a collar portion or a hem portion. Since the wale bind-off portion 3W formed in the present embodiment is similar to the rib knitting structure, by forming the end region 3 by rib knitting, the joints on both sides of the parting line SL can be made inconspicuous. However, since the final stitch of the wale bind-off portion 3W can be formed apart from the final stitch row in the wale direction even in the end region 3 of another structure, the same effect as that of the present embodiment can be obtained in terms of finish and runback prevention. Is obtained.
