Description

The present invention relates to a method for knitting a fabric that prevents fraying of knitting yarns on a flat knitting machine.

When knitting a fabric with a striped or intarsia pattern using a flat knitting machine equipped with multiple feeders, the knitting yarn is switched. When switching the knitting yarn, it is necessary to fix the knitting yarn to the fabric to prevent it from fraying. In Patent Document 1, the knitting yarn is knotted on the flat knitting machine to prevent it from fraying.

JP 2017-186694 A

The method described in Patent Document 1 knits knots by split knitting using a knitting needle with a transfer blade. The blade is formed on the side of the knitting needle. In Patent Document 1, the direction of feeder movement when performing split knitting is limited. Depending on the configuration of the knitted fabric, this limitation on the feeder movement direction may reduce the knitting efficiency of the knitted fabric.

One of the objects of the present invention is to provide a method for knitting a fabric that can easily prevent fraying of the knitting yarn, regardless of the knitting needle configuration.

<1> The knitting method of the knitted fabric of the present invention is
A knitting method for a knitted fabric, which knits a knitted fabric including a first knitted fabric portion using a flat knitting machine having a first needle bed and a second needle bed facing the first needle bed,
a fray prevention step of temporarily suspending knitting of the knitted fabric at least either before or after knitting the first knitted fabric portion on the first needle bed, and fixing a knitting yarn extending from a first feeder used for knitting the first knitted fabric portion to an existing row of stitches held on the first needle bed at that time;
The fray prevention step includes:
A step A of moving the first feeder in a first direction within the knitting width of the existing stitch row to knit an anchor stitch consisting of a hanging stitch or a tuck stitch overlapping a stitch of the existing stitch row;
a step B of moving the first feeder in a second direction opposite to the first direction, knitting a first stitch consisting of a hanging stitch on the first needle bed or the second needle bed, and retaining the first stitch on the second needle bed;
a step C of moving the first feeder in the first direction and locating it at a position beyond the first stitch;
a step D of moving the first feeder in the second direction to knit a second stitch following the first stitch in the wale direction;
a step E of overlapping the second stitch with a stitch of the existing stitch row held on the first needle bed;
and a step F of moving the first feeder in the first direction to position the first feeder at a position beyond the second stitch,
After the fray-preventing step, knitting of the knitted fabric is resumed, and stitches that are continuous in the wale direction with the double stitches formed in step E are knitted.

When the fray prevention process is carried out before knitting the first knitted fabric portion, the existing stitch row is made up of a knitted fabric portion other than the first knitted fabric portion. On the other hand, when the fray prevention process is carried out after knitting the first knitted fabric portion, the existing stitch row may be made up of (1) the first knitted fabric portion, (2) a knitted fabric portion other than the first knitted fabric portion, or (3) the first knitted fabric portion and a knitted fabric portion other than the first knitted fabric portion.

<2> In the knitting method of the knitted fabric described in <1> above,
In the step C, a third stitch is knitted at a position on the first direction side of the anchor stitch, and the third stitch is held on the second needle bed.
In the step F, a fourth stitch is knitted which is continuous with the third stitch in the wale direction,
The fray prevention step further comprises:
a process G of overlapping the fourth stitch with a stitch of the existing stitch row;
and a step H of moving the first feeder in the second direction to position it at a position beyond the fourth stitch,
After the fray-preventing step, knitting of the knitted fabric may be restarted, and stitches continuous in the wale direction of the double stitches formed in step G may be knitted.

<3> In the knitting method of the knitted fabric described in <1> or <2> above,
The fray prevention step further comprises:
A step I of knitting a fifth stitch following the anchor stitch in the wale direction after the step E;
and a step J of overlapping the fifth stitch with a stitch of the knitted fabric held on the first needle bed.

In the knitting method for knitted fabrics of the present invention, the movement of the knitting yarn is restricted by anchor stitches before fray prevention of the knitting yarn begins. This allows the knitting yarn to be fray-prevented while tension is applied to the knitting yarn.

In the knitting method for a knitted fabric of the present invention, the anchor stitch and the first stitch are knitted in opposite directions and are connected by a knitting yarn. The anchor stitch and the first stitch, which are connected by the knitting yarn, restrict each other's movement. Furthermore, as shown in the embodiment, the first stitch is twisted, and the knitting yarn is wound across the twisted first stitch. As a result, the knitting yarn fixed to the knitted fabric is less likely to fray.

In the knitting method for the knitted fabric described in <2> above, a third stitch is knitted on the opposite side of the first stitch, with the anchor stitch in between, and the third stitch and the first stitch are connected by the knitting yarn. The first stitch and the third stitch, which are connected by the knitting yarn, constrain each other's movement. In addition, the fourth stitch, which follows the third stitch in the wale direction, and the second stitch, which follows the first stitch in the wale direction, are connected by the knitting yarn, and they constrain each other's movement. Furthermore, as shown in the embodiment, the third stitch is twisted, and the knitting yarn is wound across the twisted third stitch. As a result, the knitting yarn fixed to the knitted fabric is less likely to fray.

In the knitting method for the knitted fabric described in <3> above, the fifth stitch following the anchor stitch in the wale direction restricts the movement of the anchor stitch. As a result, the knitting yarn fixed to the knitted fabric is less likely to fray.

FIG. 1 is a schematic diagram of knitwear, which is an example of a knitted fabric according to an embodiment. FIG. 2 is a first knitting process diagram illustrating a knitting method for a knitted fabric according to an embodiment. FIG. 3 is a second knitting process diagram following FIG.

The knitting method for the knitted fabric according to the embodiment will be explained below with reference to the drawings.

<Embodiment 1>
In embodiment 1, an example of knitting the knitted fabric 1 shown in FIG. 1 using the knitted fabric knitting method of the present invention will be described. The knitted fabric 1 of this example is knitwear having a body with an intarsia pattern. The body includes a base knitted fabric portion 2 that occupies the majority of the body, and multiple first knitted fabric portions 3, 4 that form the intarsia pattern. The base knitted fabric portion 2 and the first knitted fabric portions 3, 4 are different in color. The first knitted fabric portion 3 and the first knitted fabric portion 4 may be the same in color or different in color. The feeder for knitting the base knitted fabric portion 2 is different from the feeder for knitting the first knitted fabric portions 3, 4. The feeder for knitting the first knitted fabric portion 3 and the feeder for knitting the first knitted fabric portion 4 may be the same in color or different in color. When the first knitted fabric portion 3 and the first knitted fabric portion 4, which are different in color, are knitted using a single feeder, the knitting yarn fed from the feeder includes, for example, a first yarn and a second yarn connected by a splicer.

In this example, the first knitted fabric portions 3, 4 have a diamond shape. End stitches 3S, 4S, which are the starting point of knitting the first knitted fabric portions 3, 4, are arranged at the bottom of the diamond shape. End stitches 3E, 4E, which are the ending point of knitting the first knitted fabric portions 3, 4, are arranged at the top of the diamond shape. Note that the shape of the first knitted fabric portions 3, 4 may be a shape other than a diamond shape, such as a rectangle or a circle.

The knitted fabric 1 is knitted starting from the hem of the body. First, a portion of the base knitted fabric portion 2 is knitted in a tubular shape. Next, a portion of the base knitted fabric portion 2 is knitted in a C-shape, and a first knitted fabric portion 3 is knitted in the center of the base knitted fabric portion 2 in the knitting width direction. Before and after the first knitted fabric portion 3 is knitted, a knitting yarn extending from the feeder used to knit the first knitted fabric portion 3 is fixed to the base knitted fabric portion 2. After the first knitted fabric portion 3 is knitted, a portion of the base knitted fabric portion 2 is knitted in a tubular shape. Then, a portion of the base knitted fabric portion 2 is knitted in a C-shape, and a first knitted fabric portion 4 is knitted in the center of the base knitted fabric portion 2 in the knitting width direction. The first knitted fabric portion 4 is knitted in the same way as the first knitted fabric portion 3.

In this example, the first knitted fabric portions 3, 4 are knitted on the front needle bed FB. In this example, the knitting method of the present invention is applied to fix the knitting yarn to the knitted fabric 1 before knitting the first knitted fabric portion 3, after knitting the first knitted fabric portion 3, before knitting the first knitted fabric portion 4, and after knitting the first knitted fabric portion 4. Below, with reference to Figures 2 and 3, an example of knitting the thread insertion portion, which fixes the knitting yarn to the base knitted fabric portion 2 of the knitted fabric 1 before knitting the end stitch 3S of the first knitted fabric portion 3, will be described. The knitting example shown in Figures 2 and 3 is intended to prevent the knitting yarn 9Y that constitutes the thread insertion portion from fraying. In this knitting example, the feeder used to knit the first knitted fabric portion 3 is called the first feeder 9.

The flat knitting machine used in this example is a two-bed flat knitting machine. A two-bed flat knitting machine has a front needle bed FB and a back needle bed BB that face each other. In this example, the front needle bed FB is the first needle bed, and the back needle bed BB is the second needle bed. The knitting needles provided on the flat knitting machine are latch needles that include a needle body with a hook and a latch that opens and closes the hook. A blade for transferring stitches is formed on the side of the needle body of the latch needle. Unlike this example, the flat knitting machine used for knitting may also be a four-bed flat knitting machine. The knitting needles may also be compound needles that include a needle body with a hook and a slider that opens and closes the hook.

The "S + number" in the left column of Figures 2 and 3 indicates the knitting step number. The right column shows the knitting state at each knitting step. The black dots in the right column indicate the knitting needles of the front needle bed FB and the back needle bed BB. The circle marks in the right column indicate the stitches 20, 22, and 24 of the base knitted fabric portion 2 in Figure 1, and the inverted triangle mark indicates the first feeder 9. The stitches 20, 22, and 24 form the existing stitch row 5 that is held on the front needle bed FB before the first knitted fabric portion 3 is knitted. The parts related to the knitting operation at each knitting step are indicated by thick lines. The left-pointing arrows and right-pointing arrows outside the column indicate the first direction R1 and the second direction R2, respectively. The first direction R1 and the second direction R2 are the directions of movement of the first feeder 9 along the length of the needle bed.

As shown in step S1 of Figure 2, the base knit fabric portion 2 is knitted in a needle-off state. The needle-off state is a state in which an empty needle is positioned between adjacent stitches in the knitting width direction. The stitches held on the front needle bed FB and the stitches held on the back needle bed BB are offset in the knitting width direction. From this state, knitting of the knitted fabric 1 is temporarily interrupted, and a fray-stop process is carried out to secure the knitting yarn 9Y extending from the first feeder 9 to the existing stitch row 5. In step S1 related to the fray-stop process, first, the first feeder 9 is moved in a first direction R1, and an anchor stitch 10 is knitted (process A). In this example, the anchor stitch 10 is a hooked stitch formed on an empty needle of the back needle bed BB. In this example, the left direction is the first direction R1, and the right direction is the second direction R2. Knitting the anchor stitch 10 places tension on the knitting yarn extending from the first feeder 9 to the needle bed, making knitting after the anchor stitch 10 easier.

Unlike this example, if the anchor stitch 10 is knitted when the first feeder 9 moves to the right, the right direction is the first direction R1. The anchor stitch 10 may also be a tuck stitch formed in a stitch 20 of an existing stitch row 5 held on the front needle bed FB.

Next, in step S1, the first feeder 9 is moved in the second direction R2, a first stitch 11 consisting of a hang stitch is knitted, and the first stitch 11 is held on the back needle bed BB (process B). In this example, the first stitch 11 is knitted on an empty needle of the back needle bed BB. In other words, the first stitch 11 is held on the back needle bed BB at the same time as it is knitted. The first stitch 11 is positioned on the second direction R2 side of the anchor stitch 10. The knitting direction of the first stitch 11 is opposite to the knitting direction of the anchor stitch 10. Unlike this example, the first stitch 11 may also be knitted on an empty needle of the front needle bed FB. In that case, the first stitch 11 is moved to the back needle bed BB before process C, which will be described later.

In step S1, the first feeder 9 is further moved in the first direction R1 and positioned beyond the first stitch 11 (process C). In this example, the first feeder 9 is further moved in the first direction R1 and a third stitch 13 is knitted at a position closer to the anchor stitch 10 in the first direction R1. In this example, the third stitch 13 is knitted on an empty needle of the back needle bed BB. Unlike this example, the third stitch 13 may also be knitted on an empty needle of the front needle bed FB. In that case, the third stitch 13 is moved to the back needle bed BB before process D, which will be described later. The knitting direction of the third stitch 13 is opposite to that of the first stitch 11. The third stitch 13 is not a required stitch.

The anchor stitch 10 and the first stitch 11 are connected by the knitting yarn 9Y. Similarly, the first stitch 11 and the third stitch 13 are connected by the knitting yarn 9Y. The connection of the knitting yarn 9Y restricts the movement of the anchor stitch 10, the first stitch 11, and the third stitch 13 relative to one another.

In step S2, the first feeder 9 is moved in the second direction R2, and a second stitch 12 is knitted that follows the first stitch 11 in the wale direction (process D). Since the first stitch 11 is held on the back needle bed BB, the second stitch 12 is knitted on the back needle bed BB.

In step S3, the second stitch 12 is moved from the back needle bed BB to the front needle bed FB, and the second stitch 12 is overlapped on the stitch 22 of the existing stitch row 5 held on the front needle bed FB (process E). At the time of step S3, the first stitch 11 is in a twisted state. The movement of the second stitch 12 swaps the top and bottom of the knitting yarn extending from the anchor stitch 10 to the first stitch 11 with the knitting yarn extending from the second stitch 12 to the third stitch 13. As a result, the knitting yarn extending from the second stitch 12 to the third stitch 13 is wrapped around the portion of the first stitch 11 on the first direction R1 side. The first wrap of the knitting yarn is formed around the first stitch 11. The second stitch 12 is positioned inside the tubular base knitted fabric portion 2 and is difficult to see from the outside of the knitted fabric 1.

In step S4 of Figure 3, the first feeder 9 is moved in the first direction R1 and positioned beyond the second stitch 12 (process F). This movement of the first feeder 9 causes the knitting yarn 9Y extending from the second stitch 12 to the first feeder 9 to cross the twisted first stitch 11. The knitting yarn 9Y crossing the first stitch 11 wraps around the portion of the first stitch 11 on the second direction R2 side, pulling the first stitch 11 in the first direction R1. This knitting yarn wrap is the second knitting yarn wrap around the first stitch 11. Because two knitting yarn wraps are formed around one first stitch 11, the first stitch 11 is even less likely to fray.

In step S4 of this example, the first feeder 9 is further moved in the first direction R1 to knit a fourth stitch 14, which follows the third stitch 13 in the wale direction. The fourth stitch 14 is connected to the second stitch 12 by the knitting yarn 9Y. Therefore, the second stitch 12 and the fourth stitch 14 are mutually restricted in their movements, preventing fraying of the knitting yarn 9Y. Here, if the third stitch 13 is not knitted in step S1, the fourth stitch 14 is not knitted.

In step S5, the fourth stitch 14 is moved from the back needle bed BB to the front needle bed FB, and the fourth stitch 14 is overlapped with the stitch 24 of the existing stitch row 5 held on the front needle bed FB (process G). At the time of step S5, the third stitch 13 is in a twisted state. The movement of the fourth stitch 14 swaps the top and bottom of the knitting yarn extending from the first stitch 11 to the third stitch 13 with the knitting yarn extending from the second stitch 12 to the fourth stitch 14. As a result, the knitting yarn extending from the second stitch 12 to the fourth stitch 14 is wrapped around the portion of the third stitch 13 on the second direction R2 side. The first wrap of the knitting yarn is formed around the third stitch 13. The fourth stitch 14 is positioned inside the tubular base knitted fabric portion 2 and is difficult to see from the outside of the knitted fabric 1.

In step S6, the first feeder 9 is moved in the second direction R2 and positioned beyond the fourth stitch 14 (process H). This movement of the first feeder 9 causes the knitting yarn 9Y extending from the fourth stitch 14 to the first feeder 9 to cross the twisted third stitch 13. The knitting yarn 9Y crossing the third stitch 13 wraps around the portion of the third stitch 13 on the first direction R1 side, pulling the third stitch 13 in the second direction R2. This knitting yarn wrap is the second knitting yarn wrap around the third stitch 13. Because two knitting yarn wraps are formed around one third stitch 13, the third stitch 13 is even less likely to fray.

In step S6 of this example, the first feeder 9 is further moved in the second direction R2 to knit a fifth stitch 15 that follows the anchor stitch 10 in the wale direction (process I). The fifth stitch 15 is connected to the fourth stitch 14 by the knitting yarn 9Y. Therefore, the fourth stitch 14 and the fifth stitch 15 mutually restrict movement, suppressing fraying of the knitting yarn 9Y.

After step S6, the fifth stitch 15 is overlapped on the stitch 20 of the base knitted fabric portion 2 held on the front needle bed FB (process J). The fifth stitch 15 is positioned on the inside of the tubular base knitted fabric portion 2 and is difficult to see from the outside of the knitted fabric 1.

Once the knitting process described above is completed, knitting of the first knitted fabric portion 3 and the C-shaped base knitted fabric portion 2 begins. As a result, the double stitches formed in step S3 of Figure 2, step S5, and step S6 of Figure 3 are fixed. The end stitch 3S, which is the starting point of the first knitted fabric portion 3, is knitted at a position offset in the knitting width direction from, for example, the anchor stitch 10, the first stitch 11, and the third stitch 13. The end stitch 3S formed in such a position is less likely to be affected by the yarn insertion portion. Therefore, the shape of the end stitch 3S is less likely to be distorted.

The knitting method of this example makes it possible to easily prevent the knitting yarn from fraying, regardless of the knitting needle configuration. Furthermore, with the knitting method of this example, the anchor stitch 10 and the first stitch 11 pull each other in a direction toward each other, and the first stitch 11 and the third stitch 13 pull each other in a direction toward each other. Therefore, with a fabric 1 knitted using the knitting method of this example, there is no need to manually tighten the knitting yarn at the thread insertion section.

The knitting example shown in Figures 2 and 3 can also be used to knit a yarn release section that secures the knitting yarn to the base knitted fabric section 2 of the knitted fabric 1 after knitting the end stitch 3E of the first knitted fabric section 3. When knitting the yarn insertion section of the first knitted fabric section 4 after knitting the yarn release section of the first knitted fabric section 3, it is advisable to shift the first stitch 11 of the yarn release section of the first knitted fabric section 3 and the first stitch 11 of the yarn insertion section of the first knitted fabric section 4 in the knitting width direction. By dispersing the fray-prevented sections, the fray-prevented sections become less noticeable.
