Description

TECHNICAL FIELD

[0001] The present application relates to a knitting method of a knitted fabric in which a knitted yarn is prevented from being dropped out on a flat knitting machine. BACKGROUND

[0002] When a knitted fabric having a stripe pattern or a jacquard pattern is knitted using a flat knitting machine provided with a plurality of feeders, a knitted yarn is switched. At the time of switching the knitted yarn, it is necessary to fix the knitted yarn to the knitted fabric in order to prevent the knitted yarn from being dropped out. In Patent Literature 1, a knot of the knitted yarn is knitted on the flat knitting machine, thereby preventing the knitted yarn from being dropped out.

[0003] PRIOR ART DOCUMENTS

[0004] PATENT LITERATURE

[0005] Patent Literature 1: Japanese Patent Application Laid-Open No. 2017-186694

[0006] The method described in Patent Literature 1 knits a knot by using a drop of a knitting needle having a blade for transferring a stitch. The blade is formed on a side surface of the knitting needle. In Patent Literature 1, a moving direction of the feeder at the time of the drop is limited. Depending on a structure of the knitted fabric, the limitation of the moving direction of the feeder sometimes reduces a knitting efficiency of the knitted fabric. SUMMARY

[0007] PROBLEMS TO BE SOLVED BY THE INVENTION

[0008] An object of the present application is to provide a knitting method of a knitted fabric in which a knitted yarn is prevented from being dropped out simply regardless of a structure of a knitting needle.

[0009] MEANS FOR SOLVING THE PROBLEMS

[0010] <1> A knitting method of a knitted fabric knits a knitted fabric including a first knitted fabric portion using a flat knitting machine provided with a first needle bed and a second needle bed opposite to the first needle bed, wherein

[0011] The knitting method of the knitted fabric has a drop-out prevention process at least one of before the first knitted fabric portion is knitted by the first needle bed and after the first knitted fabric portion is knitted by the first needle bed, in which the knitting of the knitted fabric is temporarily interrupted, and a knitted yarn extended from a first feeder used in the knitting of the first knitted fabric portion is fixed to an existing stitch column latched in the first needle bed at the time,

[0012] The drop-out prevention process includes:

[0013] Step A, in which the first feeder is moved in a first direction within the braiding width of the existing coil column to braid an anchoring coil consisting of a hanging loop or a coiled coil overlapping the coil of the existing coil column;

[0014] Step B, in which the first feeder is moved in a second direction opposite to the first direction, and a first loop composed of loops is woven by the first needle bed or the second needle bed, and the first loop is locked onto the second needle bed.

[0015] Step C, in which the first feeder is moved in the first direction and positioned beyond the first coil;

[0016] Step D, in which the first feeder is moved in the second direction to weave a second coil that is continuous in the longitudinal direction of the first coil;

[0017] Step E, in which the second coil overlaps with the coil of the existing coil array secured to the first needle bed; and

[0018] In step F, the first feeder is moved in the first direction and positioned beyond the second coil.

[0019] After the anti-fraying process, the weaving of the fabric begins again, weaving continuous loops in the longitudinal direction of the overlapping loops formed in process E.

[0020] When the anti-loosening process is performed before the first braided section is braided, the existing coil pattern is composed of braided sections other than the first braided section. On the other hand, when the anti-loosening process is performed after the first braided section is braided, for the existing coil pattern, (1) it can be composed of the first braided section, (2) it can be composed of braided sections other than the first braided section, and (3) it can be composed of the first braided section and braided sections other than the first braided section.

[0021] <2> In the above <1> The recorded weaving methods for woven fabrics can also be,

[0022] In step C, a third loop is also woven at a position closer to the anchoring loop in the first direction, so that the third loop is secured to the second needle bed.

[0023] In step F, a fourth coil, continuous in the longitudinal direction of the third coil, is also woven.

[0024] The anti-dispersion process also includes:

[0025] Step G, in which the fourth coil overlaps with the coils of the existing coil array; and

[0026] In step H, the first feeder is moved in the second direction and positioned beyond the fourth coil.

[0027] After the anti-fraying process, the weaving of the fabric begins again, weaving continuous loops in the longitudinal direction of the overlapping loops formed in the process G.

[0028] <3> In the above <1> or <2> The recorded weaving methods for woven fabrics can also be,

[0029] The anti-dispersion process also includes:

[0030] Step I, in which a fifth continuous coil is woven in the longitudinal direction of the anchoring coil after step E; and

[0031] Step J, in which the fifth coil is overlapped with the coil of the knitted fabric that is fixed to the first needle bed.

[0032] Invention Effects

[0033] In the weaving method of the present invention, after restricting the movement of the weaving yarn by anchoring the loops, the anti-runaway treatment of the weaving yarn begins. Therefore, the anti-runaway treatment of the weaving yarn can be performed while the weaving yarn is under tension.

[0034] In the weaving method of the present invention, the anchoring coil and the first coil are woven in opposite directions and connected by the weaving yarn. The anchoring coil and the first coil, connected by the weaving yarn, constrain each other's movements. Furthermore, as shown in the embodiment, the first coil is twisted, and the weaving yarn is wound around it in a manner that passes through the twisted first coil. As a result, the weaving yarn fixed to the fabric is less likely to come undone.

[0035] In the weaving method of the fabric described in <2> above, a third coil is woven on the opposite side of the first coil, separated by an anchoring coil. This third coil and the first coil are connected by weaving yarn. The first and third coils connected by the weaving yarn mutually constrain each other's movements. Furthermore, a fourth coil continuous in the warp direction of the third coil and a second coil continuous in the warp direction of the first coil are connected by weaving yarn, mutually constraining each other's movements. Moreover, as shown in the embodiment, the third coil is twisted, and the weaving yarn is wound in a manner that passes through the twisted third coil. As a result, the weaving yarn fixed to the fabric is less likely to unravel.

[0036] In the weaving method of the fabric described in <3> above, the fifth continuous coil in the longitudinal direction of the anchor coil constrains the movement of the anchor coil. As a result, the weaving yarn fixed to the fabric is less likely to come undone. Attached Figure Description

[0059] Hereinafter, a method for weaving the fabric according to the embodiments will be described based on the accompanying drawings.

[0060] <Implementation Method 1>

[0061] In Embodiment 1, the knitting method of the present invention is used to knit the fabric. Figure 1 The example of fabric 1 shown will be used for illustration. Fabric 1 in this example is a knitted garment having a body piece with an intarsia pattern. The body piece has a base knitted section 2 occupying most of the body piece and multiple first knitted sections 3 and 4 constituting the intarsia pattern. The color of the base knitted section 2 is different from the colors of the first knitted sections 3 and 4. The color of the first knitted section 3 can be the same as or different from the color of the first knitted section 4. The feeder used for knitting the base knitted section 2 is different from the feeder used for knitting the first knitted sections 3 and 4. The feeder used for knitting the first knitted section 3 and the feeder used for knitting the first knitted section 4 can be the same as or different. When knitting the first knitted sections 3 and 4 of different colors using a single feeder, the knitting yarn supplied from that feeder includes, for example, a first yarn and a second yarn connected by a splicer.

[0062] In this example, the first braided sections 3 and 4 have a rhombus shape. End loops 3S and 4S, serving as the starting points of the braiding in the first braided sections 3 and 4, are arranged at the lower end of the rhombus shape. End loops 3E and 4E, serving as the ending points of the braiding in the first braided sections 3 and 4, are arranged at the upper end of the rhombus shape. It should be noted that the shapes of the first braided sections 3 and 4 can also be other than rhombus shapes, such as rectangular or circular shapes.

[0063] The knitted fabric 1 is knitted starting from the hem of the body piece. First, a portion of the base knitted fabric 2 is knitted in a tubular shape. Next, a portion of the base knitted fabric 2 is knitted in a C-shape, and a first knitted fabric 3 is knitted in the central portion of the base knitted fabric 2 in the knitting width direction. Before and after knitting the first knitted fabric 3, the knitting yarn extending from the feeder used in knitting the first knitted fabric 3 is fixed to the base knitted fabric 2. After knitting the first knitted fabric 3, a portion of the base knitted fabric 2 is knitted in a tubular shape. Then, a portion of the base knitted fabric 2 is knitted in a C-shape, and a first knitted fabric 4 is knitted in the central portion of the knitting width direction of the base knitted fabric 2. The first knitted fabric 4 is knitted in the same manner as the first knitted fabric 3.

[0064] In this example, the first knitted sections 3 and 4 are knitted by 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 section 3, after knitting the first knitted section 3, before knitting the first knitted section 4, and after knitting the first knitted section 4. Hereinafter, based on Figure 2 and Figure 3A weaving example is described in which the weaving yarn is fixed to the yarn entry part of the base weaving part 2 of the weaving 1 before weaving the end loop 3S of the first weaving part 3. Figure 2 and Figure 3 The knitting example shown is used to prevent the knitting yarn 9Y constituting the yarn feed section from unraveling. In this knitting example, the feeder used in the knitting of the first knitted section 3 is referred to as the first feeder 9.

[0065] The flat knitting machine used in this example is a 2-bed flat knitting machine. A 2-bed flat knitting machine has a front needle bed (FB) and a rear needle bed (BB) facing each other. In this example, the front needle bed (FB) is the first needle bed, and the rear needle bed (BB) is the second needle bed. The knitting needles used in the flat knitting machine are latch needles, which have a needle body with a hook and a latch that opens and closes the hook. A leaf blade for transferring loops is formed on the side of the needle body in the latch needle. Unlike this example, the flat knitting machine used in this example could also be a 4-bed flat knitting machine. Alternatively, the knitting needles could be composite needles with a needle body with a hook and a sliding member that opens and closes the hook.

[0066] Figure 2 and Figure 3 The "S + number" in the left column indicates the knitting process number. The right column shows the knitting status of each knitting process. The black dots in the right column indicate the knitting needles of the front needle bed (FB) and the back needle bed (BB). The circular mark in the right column indicates... Figure 1 The loops 20, 22, and 24 of the base knitted section 2 are marked with an inverted triangle to indicate the first feeder 9. Loops 20, 22, and 24 constitute the existing loop column 5 that is momentarily locked to the front needle bed FB before knitting the first knitted section 3. Parts related to the knitting action of each knitting process are indicated with thick lines. The left and right arrows outside the column represent 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.

[0067] like Figure 2 As shown in step S1, the base knitted section 2 is knitted in a needle-withdrawn state. The needle-withdrawn state refers to a state where empty needles are arranged between adjacent loops along the knitting width direction. The loops secured to the front needle bed FB and the loops secured to the rear needle bed BB are staggered in the knitting width direction. From this state, the knitting of the knitted section 1 is temporarily interrupted, and an anti-slipping process is performed to fix the knitting yarn 9Y extending from the first feeder 9 to the existing loop array 5. In step S1 of the anti-slipping process, firstly, the first feeder 9 is moved in the first direction R1, and an anchoring loop 10 is knitted (step A). ​​In this example, the anchoring loop 10 is a loop formed on the empty needles of the rear needle bed BB. In this example, the left direction is the first direction R1, and the right direction is the second direction R2. By knitting the anchoring loop 10, tension is applied to the knitting yarn extending from the first feeder 9 to the needle bed, thus making the knitting after the anchoring loop 10 easier.

[0068] Unlike this example, when the anchor coil 10 is braided while the first feeder 9 moves to the right, the right direction is the first direction R1. Alternatively, the anchor coil 10 can also be a coiled coil formed on the existing coil row 5 of the coil 20 that is fixed on the front needle bed FB.

[0069] In step S1, the first feeder 9 is then moved in the second direction R2 to knit a first loop 11 consisting of a looper, securing the first loop 11 to the rear needle bed BB (step B). In this example, the first loop 11 is knitted on an empty needle of the rear needle bed BB. That is, while knitting the first loop 11, the first loop 11 is secured to the rear needle bed BB. The first loop 11 is positioned closer to the second direction R2 side than the anchoring loop 10. The knitting direction of the first loop 11 is opposite to the knitting direction of the anchoring loop 10. Unlike this example, the first loop 11 can also be knitted on an empty needle of the front needle bed FB. In this case, the first loop 11 is moved towards the rear needle bed BB before step C described later.

[0070] In step S1, the first feeder 9 is further moved in the first direction R1, positioned beyond the first coil 11 (step C). In this example, the first feeder 9 is further moved in the first direction R1 to knit a third coil 13 at a position closer to the anchor coil 10 in the first direction R1. In this example, the third coil 13 is knitted on an empty needle of the rear needle bed BB. Unlike this example, the third coil 13 can also be knitted on an empty needle of the front needle bed FB. In this case, before step D described later, the third coil 13 is moved towards the rear needle bed BB. The knitting direction of the third coil 13 is opposite to the knitting direction of the first coil 11. The third coil 13 is not a mandatory coil.

[0071] Anchor coil 10 and first coil 11 are connected by braided yarn 9Y. Similarly, first coil 11 and third coil 13 are connected by braided yarn 9Y. Through the connection of braided yarn 9Y, anchor coil 10, first coil 11 and third coil 13 mutually constrain each other's movements.

[0072] In step S2, the first feeder 9 is moved in the second direction R2 to weave a second coil 12 that is continuous in the longitudinal direction of the first coil 11 (step D). Since the first coil 11 is fixed to the back needle bed BB, the second coil 12 is woven into the back needle bed BB.

[0073] In step S3, the second coil 12 is moved from the rear needle bed BB to the front needle bed FB, so that the second coil 12 overlaps with the coil 22 of the existing coil row 5 fixed to the front needle bed FB (step E). At the moment of step S3, the first coil 11 is in a twisted state. By moving the second coil 12, the knitting yarn extending from the anchor coil 10 to the first coil 11 and the knitting yarn extending from the second coil 12 to the third coil 13 are interchanged. As a result, the knitting yarn extending from the second coil 12 to the third coil 13 is wound around the portion of the first coil 11 on the first direction R1 side. The first winding of the knitting yarn is formed in the first coil 11. The second coil 12 is disposed inside the tubular base knitted portion 2 and is difficult to see from the outside of the knitted fabric 1.

[0074] exist Figure 3 In step S4, the first feeder 9 is moved in the first direction R1 and positioned beyond the second coil 12 (step F). Through this movement of the first feeder 9, the braided yarn 9Y extending from the second coil 12 to the first feeder 9 traverses the twisted first coil 11. The portion of the braided yarn 9Y traversing the first coil 11 wound around the second direction R2 side of the first coil 11 pulls the first coil 11 towards the first direction R1. This winding of the braided yarn is a winding of the second braided yarn of the first coil 11. Because two braided yarns are formed for one first coil 11, the first coil 11 is less likely to unravel.

[0075] In step S4 of this example, the first feeder 9 is further moved in the first direction R1 to weave a fourth coil 14 continuously in the longitudinal direction of the third coil 13. The fourth coil 14 is connected to the second coil 12 via the braiding yarn 9Y. Therefore, the second coil 12 and the fourth coil 14 mutually restrain each other's movements, suppressing the unraveling of the braiding yarn 9Y. Here, if the third coil 13 is not woven in step S1, the fourth coil 14 is not woven.

[0076] In step S5, the fourth coil 14 is moved from the rear needle bed BB to the front needle bed FB, so that the fourth coil 14 overlaps with the coil 24 of the existing coil row 5 fixed to the front needle bed FB (step G). At the moment of step S5, the third coil 13 is in a twisted state. By moving the fourth coil 14, the knitting yarn extending from the first coil 11 to the third coil 13 and the knitting yarn extending from the second coil 12 to the fourth coil 14 are interchanged. As a result, the knitting yarn extending from the second coil 12 to the fourth coil 14 is wound around the portion of the third coil 13 on the second direction R2 side. The first winding of the knitting yarn is formed in the third coil 13. The fourth coil 14 is located inside the tubular base knitted portion 2 and is difficult to see from the outside of the knitted fabric 1.

[0077] In step S6, the first feeder 9 is moved in the second direction R2, positioning itself beyond the fourth coil 14 (step H). Through this movement of the first feeder 9, the braided yarn 9Y extending from the fourth coil 14 to the first feeder 9 traverses the twisted third coil 13. The portion of the braided yarn 9Y traversing the third coil 13 wound around the first direction R1 side of the third coil 13 pulls the third coil 13 towards the second direction R2. This winding of the braided yarn is a winding of the second braided yarn of the third coil 13. Because two braided yarns are formed for one third coil 13, the third coil 13 is less prone to unraveling.

[0078] In step S6 of this example, the first feeder 9 is further moved in the second direction R2 to weave a fifth coil 15 continuously in the longitudinal direction of the anchor coil 10 (step I). The fifth coil 15 is connected to the fourth coil 14 via the braided yarn 9Y. Therefore, the fourth coil 14 and the fifth coil 15 mutually restrain each other's movements, suppressing the unraveling of the braided yarn 9Y.

[0079] After step S6, the fifth coil 15 is overlapped with the coil 20 of the base knitted section 2, which is fixed to the front needle bed FB (step J). The fifth coil 15 is located inside the tubular base knitted section 2 and is difficult to see from the outside of the knitted fabric 1.

[0080] After the weaving process described above is completed, the first woven section 3 and the C-shaped base woven section 2 are woven. As a result, in Figure 2 Step S3 Figure 3 The overlapping loops formed in steps S5 and S6 are fixed. The end loop 3S, which is the beginning of the first braided part 3, is woven at a position offset from any one of the anchor loop 10, the first loop 11, and the third loop 13 in the braiding width direction. The end loop 3S formed at such a position is less affected by the yarn entry part. Therefore, the shape of the end loop 3S is less likely to be deformed.

[0081] According to the knitting method in this example, the knitting yarn can be easily prevented from unraveling regardless of the structure of the knitting needles. Furthermore, in this knitting method, the anchor loop 10 and the first loop 11 are pulled towards each other in a direction that brings them closer together, and the first loop 11 and the third loop 13 are also pulled towards each other in a direction that brings them closer together. Therefore, in the knitted fabric 1 knitted using this method, it is not necessary to manually tighten the knitting yarn at the yarn entry point.

[0082] Figure 2 and Figure 3The knitting example shown can also be used to knit the exit section of the base knitting section 2, which fixes the knitting yarn to the knitting fabric 1, after knitting the end loop 3E of the first knitting section 3. When knitting the entry section of the first knitting section 4 after knitting the exit section of the first knitting section 3, the first loop 11 of the exit section of the first knitting section 3 and the first loop 11 of the entry section of the first knitting section 4 can be staggered in the knitting width direction. By dispersing the anti-unraveling parts, the anti-unraveling parts are less conspicuous.
