A rear knitted fabric part is formed on the rear needle bed by the front yarn feeding port and a front knitted fabric part is formed on the front needle bed by the rear yarn feeding port using the flat-knitting machine. Consequently, the front knitted fabric part and the rear knitted fabric part are connected by intersecting the first knitting yarn and the second knitting yarn at end in knitting width direction of the front knitted fabric part and the rear knitted fabric part. When intersecting the first knitting yarn and the second knitting yarn, the knitted fabric is formed so that one of end stitch of the front knitted fabric part and end stitch of the rear knitted fabric part becomes a rear stitch while the other becomes a front stitch in the knitted fabric forming method.SELECTED DRAWING: Figure 1

Description

[Technical field]

[0001] The present invention relates to a method for knitting a fabric in which a rear knitted fabric part is knitted on a rear needle bed by a front yarn feeder, a front knitted fabric part is knitted on a front needle bed by a rear yarn feeder, and both knitted fabric parts are joined together. [Background technology]

[0002] For example, Patent Document 1 discloses a method of knitting a knitted fabric by knitting a rear knitted fabric portion on a rear needle bed with a front yarn feeder and knitting a front knitted fabric portion on a front needle bed with a rear yarn feeder. The front needle bed and the rear needle bed face each other. The front yarn feeder is disposed closer to the front needle bed than the rear yarn feeder. The front yarn feeder feeds a first knitting yarn, and the rear yarn feeder feeds a second knitting yarn. The first knitting yarn and the second knitting yarn cross at the ends of the front knitted fabric portion and the rear knitted fabric portion in the knitting width direction depending on the positional relationship between the front yarn feeder and the rear yarn feeder and the progression order of both yarn feeders. This crossing of the knitting yarns joins the front knitted fabric portion and the rear knitted fabric portion. Patent Document 1 further discloses that a miss pattern is formed at the left and right boundaries between the front knitted fabric portion and the rear knitted fabric portion to make the crossing of the knitting yarns less noticeable and to make the appearance of the left and right boundaries the same.

[0003] [Patent Document 1] JP 2010-53490 A Summary of the Invention [Problem to be solved by the invention]

[0004] The miss pattern formed at the boundary between the front knitted fabric part and the back knitted fabric part may be conspicuous depending on the structure patterns of both knitted fabric parts. In such a case, there is a need to make the intersection of knitting yarns at the boundary less conspicuous by using a knitting method other than the knitting method of Patent Document 1.

[0005] One object of the present invention is to provide a method for knitting a knitted fabric that can make the intersection of knitting yarns for joining a front knitted fabric portion and a rear knitted fabric portion less noticeable. [Means for solving the problem]

[0006] The knitting method of the knitted fabric of the present invention includes the steps of: A flat knitting machine including a front needle bed, a rear needle bed opposing the front needle bed, a front yarn feeder that feeds a first knitting yarn, and a rear yarn feeder that feeds a second knitting yarn, A knitting method for a knitted fabric, in which a rear knitted fabric portion is knitted on the rear needle bed by the front side yarn feeder, and a front knitted fabric portion is knitted on the front needle bed by the rear side yarn feeder, thereby crossing the first knitting yarn and the second knitting yarn at end portions in a knitting width direction of the front knitted fabric portion and the back knitted fabric portion, When the first knitting yarn and the second knitting yarn are crossed, one of the end stitches of the front knitted fabric portion and the end stitches of the back knitted fabric portion is knitted so as to be a purl stitch and the other is knitted.

[0007] As one embodiment of the knitting method of the knitted fabric of the present invention, The flat knitting machine includes a carriage having four cam systems mounted thereon, One embodiment of the present invention is to knit the front knitted fabric portion and the back knitted fabric portion while moving the carriage in one direction. Effect of the Invention

[0008] According to the knitting method of the present invention, when the first knitting yarn and the second knitting yarn are crossed, the knitted stitches and the purl stitches are aligned on either side of the boundary between the front knitted fabric section and the back knitted fabric section. As a result, a step is formed between the knitted stitches and the purl stitches at the boundary between the two knitted fabric sections. The crossing of the knitted yarns is easily hidden by this step. Therefore, in the knitted fabric obtained by the knitting method of the present invention, the crossing of the knitted yarns joining the front knitted fabric section and the back knitted fabric section is less noticeable. In addition, the step formed by the alignment of the knitted stitches and the purl stitches is less noticeable than the miss pattern of Patent Document 1.

[0009] By knitting the front and rear fabric portions while moving the carriage in one direction, the fabric can be knitted extremely efficiently. For example, when knitting the front and rear fabric portions by circular knitting using one yarn feeder, the carriage must be moved back and forth. [Brief description of the drawings]

[0010] [Figure 1] FIG. 1 is a schematic diagram of a carriage carrying four cam systems. [Diagram 2] FIG. 2 is a first knitting step diagram of the knitting method of the knitted fabric according to the first embodiment. [Diagram 3] FIG. 3 is a second knitting process diagram following FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, a knitting method for a knitted fabric according to an embodiment will be described with reference to the drawings.

[0012] <Embodiment 1> In this embodiment, an example of an embodiment of a knitting method for a knitted fabric of the present invention using a four-bed flat knitting machine will be described with reference to the drawings.

[0013] The four-bed flat knitting machine includes a lower front needle bed, a lower back needle bed, an upper front needle bed, and an upper back needle bed. Hereinafter, the lower front needle bed, the lower back needle bed, the upper front needle bed, and the upper back needle bed are respectively referred to as FD, BD, FU, and BU. The FD and BD face each other. The FU arranged above the FD and the BU arranged above the BD face each other. The four-bed flat knitting machine further includes multiple yarn feeders and carriages. The relationship between the needle beds, yarn feeders, and carriages will be briefly explained using the schematic diagram of FIG. 1.

[0014] FIG. 1 is a schematic diagram of a part of a flat knitting machine 5 seen from the FD side. In FIG. 1, FU is omitted. A carriage 6 provided in the flat knitting machine 5 moves back and forth on the needle bed. In this example, the carriage 6 has four cam systems 6A, 6B, 6C, and 6D arranged in the longitudinal direction of the needle bed. Each cam system has a cam corresponding to FD, BD, FU, and BU. Also, FIG. 1 shows, of the multiple yarn feeders, a front yarn feeder 8 arranged on the FD, FU side, and a rear yarn feeder 9 arranged on the BD, BU side of the front yarn feeder 8. The yarn feeders 8 and 9 are attached to rails 7 arranged above the needle beds so as to be able to run.

[0015] Next, an example of a method for knitting a fabric using the flat knitting machine 5 shown in Fig. 1 will be described with reference to Fig. 2 and Fig. 3. "S+number" in the left column of Fig. 2 and Fig. 3 indicates the number of the knitting process. The right column shows the knitting state of the stitches in each knitting process. The black dots in the right column indicate knitting needles, and the inverted triangle marks indicate the front yarn feeder 8 or the rear yarn feeder 9. The straight arrow indicates stitch transfer. The newly knitted stitches in each knitting process are shown in thick lines.

[0016] S0 in Fig. 1 shows a state in which the front knitted fabric portion 2 is held in the FD, and the back knitted fabric portion 3 is held in the BD. The front knitted fabric portion 2 is knitted with a second knitting yarn 9Y fed from a rear yarn feeder 9. The back knitted fabric portion 3 is knitted with a first knitting yarn 8Y fed from a front yarn feeder 8. In this example, the knitting method of the knitted fabric of the present invention is performed at the left and right ends of the knitted fabric 1 from this state of S0, and a tubular knitted fabric 1 is knitted. The knitted fabric 1 is knitted by all needle knitting. All needle knitting means that knitting is performed with no empty needles between adjacent stitches.

[0017] In S1, the rear yarn feeder 9 is moved to the right to knit a new front knitted fabric section 2. All stitches of the new front knitted fabric section 2 are face stitches. A face stitch is a stitch that is pulled out from the old stitches from the inside to the outside of the tubular knitted fabric 1. Unlike this example, the rear knitted fabric section 3 may be knitted first.

[0018] In S2, of the left end stitch 3L and the right end stitch 3R in the knitting width direction of the back knitted fabric portion 3, the right end stitch 3R is transferred from BD to FU. The stitches in the back knitted fabric portion 3 other than the end stitch 3R remain engaged in BD.

[0019] In S3, the front yarn feeder 8 is moved rightward to knit a new back knitted fabric section 3. In the new back knitted fabric section 3, the end stitch 3R on the right side is a purl stitch, and the stitches other than the end stitch 3R are face stitches. The purl stitches are stitches pulled out from the old stitches from the outside to the inside of the tubular knitted fabric 1. As a result of S3, the first knitting yarn 8Y and the second knitting yarn 9Y cross each other on the outside of the knitted fabric 1 in the knitting width direction.

[0020] In S4, the end stitch 3R of the back knitted portion 3 formed in FU in S3 is transferred to BD. By S4, all stitches of the front knitted portion 2 are held in FD, and all stitches of the back knitted portion 3 are held in BD. The end stitch 2R and the end stitch 3R are arranged at positions sandwiching the boundary between the front knitted portion 2 and the back knitted portion 3 on the right side of the page. The end stitch 2R is a knit stitch, and the end stitch 3R is a purl stitch.

[0021] The knitting indicated by S1 to S4 is performed by unidirectional movement of the carriage 6 (see FIG. 1). Specifically, the knitting of S1, S2, S3, and S4 is performed by cam system 6A, cam system 6B, cam system 6C, and cam system 6D, respectively, mounted on the carriage 6. In other words, by moving the carriage 6 in one direction, the knitting of the front knitted fabric portion 2, the transfer of the end stitch 3R of the back knitted fabric portion 3 on the traveling direction side of the carriage 6, the knitting of the back knitted fabric portion 3, and the return of the end stitch 3R to the original needle bed are performed in this order.

[0022] In S5 of Fig. 3, of the end stitch 2L on the left side and the end stitch 2R on the right side in the knitting width direction of the front knitted fabric portion 2, the left end stitch 2L is transferred from FD to BU. The stitches in the front knitted fabric portion 2 other than the end stitch 2L remain engaged in the FD.

[0023] In S6, the rear yarn feeder 9 is moved leftward to knit a new front knitted section 2. The left end stitch 2L of the new front knitted section 2 is purl, and the stitches other than the end stitch 2L are knit. As a result of S6, the first knitting yarn 8Y and the second knitting yarn 9Y that cross each other at the right end of the knitted fabric 1 are entangled, and the front knitted section 2 and the back knitted section 3 are joined.

[0024] In S7, the end stitch 2L formed in BU in S6 is transferred from BU to FD.

[0025] In S8, the front yarn feeder 8 is moved leftward to knit a new back knitted portion 3. All the stitches of the new back knitted portion 3 are face stitches. Therefore, the end stitch 2L and the end stitch 3L on either side of the boundary between the front knitted portion 2 and the back knitted portion 3 on the left side of the page are purl stitches and face stitches, respectively. Unlike this example, one of the end stitches on the right side of S6 and the end stitches on the right side of S8 may be a face stitch and the other a purl stitch.

[0026] The knitting shown in S5 to S8 is performed by moving the carriage 6 (see FIG. 1) in one direction. Specifically, the knitting of S5, S6, S7, and S8 is performed by cam system 6D, cam system 6C, cam system 6B, and cam system 6A, respectively, which are mounted on the carriage 6. In other words, by moving the carriage 6 in one direction, the transfer of the end stitch 2L of the front knitted fabric section 2 on the moving direction side of the carriage 6, knitting of the front knitted fabric section 2, returning the end stitch 2L to the original needle bed, and knitting of the back knitted fabric section 3 are performed in this order.

[0027] From S8 onwards, by repeating knitting similar to S1 to S8, a tubular knitted fabric 1 can be knitted, which includes a front knitted fabric portion 2 and a back knitted fabric portion 3 joined by the intersection of the first knitting yarn 8Y and the second knitting yarn 9Y. In this knitted fabric 1, the front knitted fabric portion 2 and the back knitted fabric portion 3 are lined up on either side of the boundary between them. As a result, a step is formed between the front knitted fabric portion 2 and the back knitted fabric portion 3 at the boundary position. The intersection of the knitting yarns 8Y and 9Y is easily hidden by this step. Therefore, in the knitted fabric 1 obtained by the knitting method of the knitted fabric of the present invention, the intersection of the knitting yarns 8Y and 9Y joining the front knitted fabric portion 2 and the back knitted fabric portion 3 is less noticeable. The step is less noticeable than the miss pattern of Patent Document 1.

[0028] Here, if the knitted stitches and purl stitches are arranged on either side of the boundary between the front knitted fabric portion 2 and the back knitted fabric portion 3, the intersection of the knitting yarns 8Y, 9Y at the boundary is less noticeable. Therefore, the combination of knitted stitches and purl stitches at the boundary is not limited to the combination of the end stitches 2L, 3R being purl stitches and the end stitches 2R, 3L being knit stitches as illustrated in Figures 2 and 3. For example, the end stitches 2L, 3R may be knitted and the end stitches 2R, 3L may be purl stitches.

[0029] According to the knitting method of the knitted fabric of this example, two stages of the front knitted fabric section 2 and the back knitted fabric section 3 can be knitted during one reciprocating movement of the carriage 6. Also, in this example, there is no empty course where only the movement of the carriage 6 is performed. Therefore, the knitted fabric 1 can be completed efficiently.

[0030] <Other embodiments> In the embodiment, the front knitted fabric portion 2 and the back knitted fabric portion 3 are made of a plain stitch structure, but they can also be made of a rib structure, garter structure, or other structure patterns. For example, the front knitted fabric portion 2 and the back knitted fabric portion 3 can be made of a rib structure. In that case, it is recommended that some of the stitches of the back knitted fabric portion 3 are transferred to FU in S2, and some of the stitches of the front knitted fabric portion 2 are transferred to BU in S5. If not only the end stitches 2L, 3R but also the stitches adjacent to the end stitches 2L, 3R are purl stitched as in the rib structure, the intersection of the knitting yarns 8Y, 9Y becomes even more easily hidden by the step.

[0031] The front knitted fabric portion 2 and the back knitted fabric portion 3 may be knitted in a C-shape. In that case, the knitted fabric portions 2, 3 are joined at one end in the knitting width direction of both knitted fabric portions 2, 3, and are not joined at the other end.

[0032] The knitting method of the knitted fabric of the present invention can also be implemented by a flat knitting machine equipped with two or three cam systems. The knitting method of the knitted fabric of the present invention can also be implemented by a two-bed flat knitting machine. When using a two-bed flat knitting machine, the front knitted fabric section and the back knitted fabric section are knitted by needle-free knitting. Needle-free knitting means knitting with empty needles arranged between adjacent stitches. The empty needles arranged between adjacent stitches are used for transferring stitches and forming stitches. [Explanation of symbols]
