Method for braiding a tubular braid

Abstract

A knitting method of a tubular knitted fabric, which can make a knitting thread difficult to be pulled out without hand work. In knitting a tubular knitted fabric including a first knitted fabric portion, a knitting thread extending from a first thread feeder used in knitting of the first knitted fabric portion is prevented from being pulled out. A first thread feeder is moved to a first direction, and a first loop is knitted. A specific loop in a loop row existing in the vicinity of the first loop is moved to a first needle bed from a second needle bed of a flat knitting machine, and a specific knitting needle in which the specific loop is latched is made to be an empty needle. The first loop is moved to the specific knitting needle. The first loop is increased in number of needles, and a second loop pulled out from the first loop is knitted. An overlapping loop in which the second loop is overlapped on the first loop is formed. The specific loop is returned to the specific knitting needle. The end loop is continuously knitted in a loop longitudinal direction of the overlapping loop.

Description

Technical Field

[0001] This invention relates to a method for weaving tubular fabrics on a flat knitting machine to prevent the braided yarns from coming loose. Background Technology

[0002] When knitting fabrics with patterns such as stripes or inlays using a flat knitting machine equipped with multiple thread feeders, it is necessary to switch the knitting thread. When switching the knitting thread, it is necessary to secure the knitting thread to the fabric to prevent it from coming undone. In Patent Document 1, the knitting thread is prevented from coming undone by tying a knot on the flat knitting machine.

[0006] The problem that the invention aims to solve

[0007] In the method described in Patent Document 1, after the weaving is performed by a horizontal knitting machine, the knots of the knitting threads need to be tied manually. If there are many parts where the knitting threads are switched, this manual operation is time-consuming.

[0008] One of the objectives of this invention is to provide a method for weaving tubular fabrics that prevents the yarn from unraveling without requiring manual labor.

[0009] The means to solve the problem

[0010] <1> The method for knitting a tubular knitted fabric according to the present invention uses a flat knitting machine equipped with a first needle bed and a second needle bed facing the first needle bed to knit a tubular knitted fabric including a first knitted fabric section in a total needle state. The method includes an anti-loosening step in which, when knitting a first loop following the terminal loop of the first knitted fabric section by the first needle bed, a knitting thread extending from a first thread feeder used in the knitting of the first knitted fabric section 3 is fixed to the first loop. The anti-loosening step includes steps A, B, C, D, E, and F. In step A, the first thread feeder is moved in a first direction to knit the first loop. In step B, a specific loop that is near the first loop in the existing loop column that was locked on the second needle bed before step A is moved toward the first needle bed, and the specific knitting needle that locked the specific loop becomes an empty needle. In step C, the first loop is moved toward the specific knitting needle. In step D, a needle is added to the first loop, and a second loop pulled from the first loop is knitted on the specific knitting needle. In step E, an overlapping loop is formed that overlaps the second loop on the first loop. In step F, the specific loop is returned to the specific knitting needle, and the terminal loop is continuously knitted in the longitudinal direction of the overlapping loop.

[0011] Here, the first coil is the coil that forms the basis for weaving the terminal coil. That is, the first coil is the coil in which the terminal coil is continuously woven in the warp direction of the coil. In the weaving method of the tubular braid of the present invention, the terminal coil is continuously woven in the warp direction of the overlapping coils, including the first coil. It doesn't matter which step A or step B is performed in the order described above.

[0012] <2> In the method of weaving the tubular braid described in <1> above, there is a step X, which is performed after step D and before step E, by moving the first wire feeder in the same direction as the weaving direction of the second coil, and weaving a new second coil that is continuous in the longitudinal direction of the second coil.

[0013] <3> In the method of weaving the tubular braid described in <1> or <2> above, the terminal coil is woven by moving the first wire feeder in a second direction opposite to the first direction.

[0014] The effects of the invention

[0015] In the method of knitting the tubular knitted fabric of the present invention, a first loop is knitted next to the terminal loop of the first knitted portion, and then a second loop pulled out from the first loop is knitted by increasing stitches. As a result, the knitting yarn connecting the second loop and the first loop is wound around the first loop, making the first loop difficult to move. Furthermore, in the method of knitting the tubular knitted fabric of the present invention, by forming an overlapping loop that overlaps the first and second loops, and continuously knitting the terminal loop in the warp direction of the overlapping loop, the terminal loop fixes the first loop, which has become difficult to move due to the winding of the knitting yarn. That is, in the method of knitting the tubular knitted fabric of the present invention, anti-unraveling is performed not relative to the terminal loop, but relative to the first loop next to the terminal loop. Because the first loop is very difficult to unravel, it is not necessary to manually tighten the winding of the knitting yarn relative to the first loop. The terminal loop, which is continuous in the warp direction of the difficult-to-unravel first loop, also becomes difficult to unravel.

[0016] In the method for weaving the tubular braid described in <2> above, a new second coil is continuously woven in the longitudinal direction of the second coil woven in step D. In this case, as shown in the embodiment described later, since the braiding thread is wound twice relative to the first coil, the first coil becomes more difficult to unravel. Furthermore, the weaving direction of the second coil in step D is the same as the weaving direction of the new second coil in step X. In this case, as shown in the embodiment described later, since the braiding thread is wound once on the right side and once on the left side of the first coil, the first coil is less likely to become crooked and is thus neatly formed.

[0017] In the weaving method of the tubular braid described in <3> above, the weaving direction of the first coil is a first direction, and the weaving direction of the terminal coils that are continuous in the longitudinal direction of the first coil is a second direction. The first coil woven in the first direction tends to stretch in the first direction, and the terminal coil woven in the second direction tends to stretch in the second direction. The tension acting on the first coil and the tension acting on the terminal coil roughly cancel each other out, and the first coil and the terminal coil tend to become straight in the longitudinal direction of the coils.

[0022] In order to implement the invention

[0023] The following describes a method for weaving a tubular braided fabric according to an embodiment, based on the accompanying drawings.

[0024] <Implementation Method 1>

[0025] In Embodiment 1, the weaving method of the tubular braided fabric of the present invention is described. Figure 1 The example shown is a tubular knitted fabric 1. In this example, the tubular knitted fabric 1 is a knitted garment with large front and back panels, which have an intarsia pattern. The front and back panels have a base knitted section 2 occupying most of the front and back panels and multiple first knitted sections 3 and 4 constituting the intarsia pattern. The base knitted section 2 is a different color from the first knitted sections 3 and 4. The colors of the first knitted sections 3 and 4 can be the same or different. The yarn feeder used for knitting the base knitted section 2 is different from the yarn feeder used for knitting the first knitted sections 3 and 4. The yarn feeder used for knitting the first knitted section 3 and the yarn feeder used for knitting the first knitted section 4 can be the same or different. When the first knitted sections 3 and 4 of different colors are knitted by a single yarn feeder, the knitting yarn supplied from that yarn feeder includes, for example, a first thread and a second thread connected by a splicer.

[0026] In this example, the first braided sections 3 and 4 have a diamond shape. Beginning coils 3S and 4S, which are the initial coils of the first braided sections 3 and 4, are arranged at the lower end of the diamond shape. Terminal coils 3E and 4E, which are the final coils of the first braided sections 3 and 4, are arranged at the upper end of the diamond shape. Furthermore, the shapes of the first braided sections 3 and 4 can be other than diamond shapes, such as rectangular or circular shapes.

[0027] The tubular knitted fabric 1 is knitted from the lower hem of the front and back panels. First, a portion of the base knitted fabric 2 is knitted into a tubular shape. Next, a portion of the base knitted fabric 2 is knitted into 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. Once the first knitted fabric 3 is finished, a portion of the base knitted fabric 2 is knitted into a tubular shape. Thereafter, a portion of the base knitted fabric 2 is knitted into a C-shape, and a first knitted fabric 4 is knitted in the central portion of the base knitted fabric 2 in the knitting width direction. The first knitted fabric 4 is knitted in the same manner as the first knitted fabric 3.

[0028] In this example, the weaving method of the tubular braided fabric of the present invention fixes the braiding yarn constituting the first braided part 3 to the first braided part 3 before weaving the terminal loop 3E of the first braided part 3, and fixes the braiding yarn constituting the first braided part 4 to the first braided part 4 before weaving the terminal loop 4E of the first braided part 4. Hereinafter, based on... Figure 2 and Figure 3 This describes a weaving example in which the braiding yarn constituting the first braided section 3 is fixed to the yarn exit section of the tubular braided fabric 1 before the terminal loop 3E of the first braided section 3 is woven. Figure 2 and Figure 3 The weaving example shown is an example of how to prevent the weaving yarn 9Y that constitutes the yarn section from coming loose.

[0029] The flat knitting machine used in this example is a four-bed flat knitting machine. The four-bed flat knitting machine has a lower first needle bed, a lower second needle bed, an upper first needle bed, and an upper second needle bed. Hereinafter, the lower first needle bed, lower second needle bed, upper first needle bed, and upper second needle bed will be labeled FD, BD, FU, and BU, respectively. FD and BD face each other. FU, located above FD, and BU, located above BD, face each other. FD and FU, and BD and BU, can move laterally relative to each other. In Embodiment 1, BU is not used. The flat knitting machine can also be a two-bed flat knitting machine. The knitting needles in the flat knitting machine are combination needles having a needle body with a hook and a guide plate for opening and closing the hook. The needle body has a hook, and the guide plate opens and closes the hook. The guide plate has two blades that clamp the needle body. The combination needle can also have a holding mechanism that temporarily holds the loop in the guide plate.

[0030] Figure 2 and Figure 3 The "S + number" in the left column indicates the knitting process number. The right column indicates the knitting status within each process. The black dots in the right column represent the knitting needles for FD, BD, and FU. The knitting needles for BU are not shown in the diagram. The diamond mark in the right column indicates... Figure 1 The loops of the base knitted section 2 are indicated by circles, and the loops of the first knitted section 3 are indicated by circles. The inverted triangle indicates the first thread feeder 9. In this example, the portion of the base knitted section 2 that is secured to the BD is referred to as the existing loop column 5. The portions related to the knitting action of each knitting process are indicated by thick lines. The right-hand and left-hand 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 thread feeder 9 along the length of the needle bed.

[0031] exist Figure 2 In step S0, it indicates that the weaving has been completed. Figure 1The state of the third-to-last braided coil row in the first braided section 3. This braided coil row corresponds to the vicinity of the upper end of the diamond shape. In the braiding process following this state, the second-to-last braided coil row, including the first coil 11, is braided, and then the final braided coil row, including the terminal coil 3E, is braided. In this example, the second braided coil row is composed of the first coil 11, and the final braided coil row is composed of the terminal coil 3E.

[0032] In step S0, the loops of the first knitted section 3 are secured to knitting needles E, F, and G of FD. The loops of the base knitted section 2 are secured to knitting needles A, B, C, D, H, I, J, and K of FD and knitting needles A to K of BD. The base knitted section 2 is knitted into a C-shape. The base knitted section 2 and the first knitted section 3 are knitted in a total stitch state. The total stitch state refers to the state where there are no empty stitches between adjacent loops in the knitting width direction. In step S0, the connection between the loops is illustrated, but after step S1, the connection between the loops shown in step S0 is omitted.

[0033] In step S1, the first yarn feeder 9 is moved in the first direction R1, and after the looped coil 10 is woven on the knitting needle D of FD, the terminal coil 3E is woven (refer to...). Figure 1 The first coil 11 preceding the first braided section 3 (step A). ​​The first coil 11 is the coil of the second-to-last row of braided coils in the first braided section 3. As described later, the terminal coil 3E is braided in the longitudinal direction of the first coil 11. That is, the first coil 11 is the coil continuously braided in the longitudinal direction of the terminal coil 3E, i.e., the coil that forms the basis of the terminal coil 3E. The tuck coil 10 is a coil used to connect the base braided section 2 and the first braided section 3 in the braid width direction. The braiding of the first coil 11 is easily performed by the tuck coil 10. The tuck coil 10 is not necessary.

[0034] In step S2, the first wire feeder 9 is moved in the second direction R2 and stopped at a position beyond the first coil 11. The second direction R2 is the opposite direction of the first direction R1.

[0035] In step S3, the specific loop 50, which is locked on the knitting needle F of BD, is moved towards the knitting needle G of FU, making knitting needle F an empty needle (step B). The specific loop 50 is the loop that is located near the first loop 11 at the time of step S2. The specific loop 50 can be a loop located opposite the first loop 11, or it can be a loop located next to one or two loops of the loop located opposite the first loop 11. The knitting needle F of BD is the specific knitting needle 6 with the specific loop 50 locked. Here, if the knitting needle is a combination needle with a holding mechanism, the specific loop 50 can also be temporarily stored on the combination needle FD with the loop already locked.

[0036] In step S3, the first coil 11 is further moved toward the specific knitting needle 6, which has become an empty needle (step C). In step S2, by retracting the first thread feeder 9 toward the second direction R2, the knitting thread 9Y can be prevented from wrapping around the first coil 11 when the first coil 11 is moved in step S3.

[0037] In step S4, the first yarn feeder 9 is moved in the first direction R1 and stopped at a position beyond the first loop 11. In step S5, the first yarn feeder 9 is moved in the second direction R2 to add a stitch to the first loop 11 (step D). Adding stitches is a well-known knitting method. In this example, the first loop 11, which is fixed on the knitting needle F of BD (i.e., the specific knitting needle 6), is moved towards the knitting needle F of FD, and the knitting yarn 9Y is pulled out from the first loop 11 to form the second loop 12. The second loop 12 is fixed on the specific knitting needle 6.

[0038] In this example, after the first coil 11 is braided in the first direction R1 in step S1, the second coil 12 is braided in the second direction R2 in step S5. Therefore, the braided yarn connecting the second coil 12 and the first coil 11 is wound around the portion of the first coil 11 on the first direction R1 side. The first coil 11 becomes difficult to move due to the winding of the first braided yarn 9Y relative to the first coil 11.

[0039] Alternatively, unlike this example, after step S3, the first thread feeder 9 is moved in the first direction R1 to add needles to the first coil 11. In this case, the braided yarn connecting the second coil 12 and the first coil 11 is wound around the portion of the first coil 11 on the second direction R2 side.

[0040] In step S6, the first wire feeder 9 is moved in the first direction R1, and then stops at a position past the second coil 12. Figure 3In step S7, the first thread feeder 9 is moved in the second direction R2, and a new second coil 12 is woven continuously in the longitudinal direction of the second coil 12 (step X). By weaving the new second coil 12, the second coil 12 woven in step S5 by adding needles is removed from the needle bed. In addition, by weaving the new second coil 12, the knitting thread connecting the second coil 12 woven in step S5 and the first coil 11 is also wound around the portion of the first coil 11 on the second direction R2 side. The first coil 11 becomes more difficult to unwind due to the winding of the second knitting thread 9Y relative to the first coil 11. In particular, in this example, because the knitting thread 9Y is wound once on the right and once on the left side of the first coil 11, the first coil 11 is less likely to be crooked and is neatly made. If the first coil 11 is neatly made, the terminal coil 3E that is continuous in the longitudinal direction of the first coil 11 is also neatly made.

[0041] Next, in step S7, a tufted loop 15 is knitted on the knitting needle C of FD. The tufted loop 15 is used for knitting to connect the base knitted portion 2 and the first knitted portion 3 in the knitting width direction.

[0042] In step S8, the first yarn feeder 9 is moved in the first direction R1 and stopped at a position beyond the second coil 12. In step S9, the second coil 12, which is locked on the knitting needle F of BD, is moved towards the knitting needle F of FD. That is, an overlapping coil 13 is formed, in which the second coil 12 overlaps the first coil 11 (step E). The second coil 12 is hidden inside the tubular shape of the tubular knitted fabric 1 and is difficult to notice.

[0043] In step S10, the first thread feeder 9 is moved in the second direction R2 and stopped at a position beyond the overlapping coil 13. In step S11, the specific coil 50 is returned to the specific knitting needle 6 (step F). In step S10, by retracting the first thread feeder 9 in the second direction R2, the winding of the knitting yarn 9Y can be suppressed during the movement of the specific coil 50 in step S11.

[0044] In step S12, the first thread feeder 9 is moved in the first direction R1 and stopped at a position beyond the overlapping coil 13. In step S13, the first thread feeder 9 is moved in the second direction R2, and a looped coil 16 is woven on the knitting needle G of FD. Furthermore, in step S13, the terminal coil 3E is continuously woven in the coil warp direction of the overlapping coil 13. The movement of the first thread feeder 9 in step S12 allows the weaving direction of the terminal coil 3E to become the second direction R2. By continuously weaving the terminal coil 3E in the coil warp direction of the overlapping coil 13, the first coil 11, which has become difficult to move due to the knitting thread 9Y being wound twice, is fixed. That is, in this example, anti-unraveling is performed relative to the first coil 11, which is not the terminal coil 3E. The terminal coil 3E, which is continuous in the coil warp direction of the difficult-to-unravel first coil 11, also becomes difficult to unravel.

[0045] In this example, the first coil 11 is woven toward the first direction R1 (see reference). Figure 2 In step S1), the terminal coil 3E is braided toward the second direction R2. The first coil 11, braided toward the first direction R1, is easily stretched toward the first direction R1, and the terminal coil 3E, braided toward the second direction R2, is easily stretched toward the second direction R2. The tension acting on the first coil 11 and the tension acting on the terminal coil 3E cancel each other out, and the first coil 11 and the terminal coil 3E easily become straight in the longitudinal direction of the coils.

[0046] The first braided section 3 is woven using the braiding process described above, and the braiding thread 9Y constituting the first braided section 3 is prevented from unraveling by the first loop 11 of the first braided section 3. Alternatively, after the weaving of the first braided section 3 is completed, the braiding thread 9Y extending from the first thread feeder 9 can be connected to the base braided section 2 by a loop.

[0047] As other embodiments, such as Figure 4 As shown, the weaving method of the tubular braided fabric of the present invention can also be applied to the weaving of a tubular braided fabric 1 having a first braided fabric portion 3 with a rectangular shape. Figure 4 In this case, the final row of loops in the first braided section 3 is woven towards the right side of the paper. The terminal loops 3E are woven to be hidden inside the base braided section 2. By doing so, the appearance of the first braided section 3 is not compromised on the surface of the tubular braid 1.

[0048] A flat knitting machine can also be a flat knitting machine with transfer needle beds on the upper part of both the FD and BD. In this case, the transfer needle bed located on the upper part of the FD is considered as the first needle bed, and the transfer needle bed located on the upper part of the BD is considered as the second needle bed.
