Description

[Technical field]

[0001] The present invention relates to a knitted fabric having a rope pattern and a knitting method for a rope pattern. [Background technology]

[0002] A rope pattern can be knitted within the knitting width of the base knitted fabric using a flat knitting machine. The rope pattern is a structure pattern knitted by switching the positions of the first stitch row and the second stitch row arranged within the knitting width of the base knitted fabric. For example, a rope pattern knitting method is known in which the positions of the first stitch row and the second stitch row are switched at once using racking and stitch transfer.

[0003] When the number of stitches in the first knitting row and the number of stitches in the second knitting row that constitute the rope pattern are large, it is difficult to switch the positions of the first knitting row and the second knitting row at once. For example, when the number of stitches in each knitting row is four or more, the knitting yarn connecting the first knitting row and the base knitted fabric part and the knitting yarn connecting the second knitting row and the base knitted fabric part may break when switching between the first knitting row and the second knitting row. To address this problem, Patent Document 1 discloses a method of knitting a rope pattern by gradually switching between the stitches of the first knitting row and the stitches of the second knitting row to suppress yarn breakage.

[0004] [Patent Document 1] JP 2016-020546 A Summary of the Invention [Problem to be solved by the invention]

[0005] The rope pattern knitting method of Patent Document 1 is a method that can knit a rope pattern without being limited by the texture pattern of the base knitted fabric portion or the knitting width of the rope pattern, so the number of knitting steps increases.

[0006] One object of the present invention is to provide a method for knitting a rope pattern which can knit a rope pattern simply and easily regardless of the knitting width of the rope pattern, and a knitted fabric obtained by the method for knitting the rope pattern. [Means for solving the problem]

[0007] The knitted fabric having a rope pattern of the present invention is A base knitted fabric portion and a rope pattern arranged within the knitting width of the base knitted fabric portion, The base knitted fabric portion includes a first base portion and a second base portion that sandwich the rope pattern in the knitting width direction of the base knitted fabric portion, The rope pattern has a first rope pattern portion and a second rope pattern portion that extend toward the wale direction of the base knitted fabric portion while repeatedly crossing the knitting width direction of the base knitted fabric portion, The first rope handle portion includes a first interchanging portion that intersects with the second rope handle portion, The second rope handle portion includes a second interchange portion that intersects with the first rope handle portion, The first replacement section and the second replacement section each include a plurality of stitch rows that are continuous in the wale direction, The number of the plurality of stitch rows is greater than the number of stitch rows continuing in the wale direction of the base knitted fabric portion at the intersection of the first replacement portion and the second replacement portion, The first replacement portion and the second replacement portion are not connected to each other, and are not connected to the first base portion and the second base portion.

[0008] As one embodiment of the knitted fabric having a rope pattern of the present invention, The number of stitch rows continuing in the wale direction in the first exchange section is 50% or more and 120% or less of the number of stitches arranged in the knitting width direction in the first exchange section, The number of stitch rows continuing in the wale direction in the second exchange portion may be 50% or more and 120% or less of the number of stitches aligned in the knitting width direction in the second exchange portion.

[0009] The method for knitting a rope pattern of the present invention comprises the steps of: A flat knitting machine is provided with a first needle bed and a second needle bed facing each other, and the first needle bed and the second needle bed can be relatively racked. A method for knitting a rope pattern in which a rope pattern is arranged within the knitting width of a base knitted fabric portion, Steps A, B, and C are performed from a state in which the first base stitch row, the first stitch row, the second stitch row, and the second base stitch row are aligned in the knitting width direction on the first needle bed; In the step A, the number of courses of the first knitting row is increased without knitting the first base knitting row, the second knitting row, and the second base knitting row; In the step B, the number of courses of the second knitting row is increased without knitting the first base knitting row, the first knitting row, and the second base knitting row; In the process C, the left and right positions of the last first stitch row knitted in the process A and the last second stitch row knitted in the process B are interchanged.

[0010] As one embodiment of the method for knitting a rope pattern of the present invention, Among racking directions, a direction in which the first base stitch row is arranged is a first direction, and a direction in which the second base stitch row is arranged is a second direction; The step A comprises: A step A1 of moving the first base stitch row to the second needle bed; and a step A2 of repeating a plurality of times the step of racking the second needle bed relative to the first needle bed in the first direction, and then knitting a new first stitch row continuing in a wale direction of the first stitch row, The step B is A step B1 of moving the second base stitch row to the second needle bed; An example embodiment includes a process B2 in which the second needle bed is racked relative to the first needle bed in the second direction, and then a new second stitch row that continues in the wale direction of the second stitch row is knitted multiple times. Effect of the Invention

[0011] The knitted fabric having the rope pattern of the present invention is easily knitted by the knitting method of the rope pattern of the present invention described above. The knitting method of the rope pattern of the present invention can easily knit the rope pattern regardless of the knitting width of the rope pattern. The knitting method of the rope pattern of the present invention is particularly effective when the number of stitches in the knitting width direction of each of the first exchange section and the second exchange section is 4 or more. Therefore, a knitted fabric having a rope pattern with a high degree of freedom in the design of the rope pattern is knitted. A knitted fabric having such a rope pattern can meet the diverse needs of consumers.

[0012] In the knitted fabric having the rope pattern of the present invention, the number of knitted courses in the first exchange section and the number of knitted courses in the second exchange section in the exchange area are large. The number of knitted courses here refers to the number of stitch rows arranged in the wale direction. If the number of knitted courses in the first exchange section and the number of knitted courses in the second exchange section are large, the rope pattern is formed three-dimensionally in the exchange area. Therefore, the knitted fabric having the rope pattern of the present invention has an excellent appearance.

[0013] In the knitted fabric having a rope pattern of the present invention, if the number of stitch rows in the replacement section is 50% or more of the number of stitches in the replacement section, yarn breakage is unlikely to occur in the replacement area when knitting the knitted fabric having a rope pattern. Also, if the number of stitch rows in the replacement section is 120% or less of the number of stitches in the replacement section, slack in the rope pattern in the replacement area is suppressed.

[0014] According to the knitting method of the rope pattern of the present invention, the rope pattern can be easily knitted regardless of the knitting width of the rope pattern. In the knitting method of the rope pattern of the present invention, after knitting only a plurality of first stitch rows that are continuous in the wale direction, knitting only a plurality of second stitch rows that are continuous in the wale direction. In this way, the first base stitch row, the first stitch row, the second stitch row, and the second base stitch row are separated. Therefore, even if the positions of the first stitch row and the second stitch row are suddenly switched, yarn breakage is unlikely to occur.

[0015] By knitting a new first stitch row while gradually moving the first base stitch row in the first direction, it is easy to increase the number of new first stitch rows that are continuous in the wale direction. Also, by knitting a new second stitch row while gradually moving the second base stitch row in the second direction, it is easy to increase the number of new second stitch rows that are continuous in the wale direction. Details of these effects will be described in the embodiment described later. [Brief description of the drawings]

[0016] [Figure 1] FIG. 1 is a photograph showing a part of a knitted fabric having a rope pattern according to an embodiment. [Diagram 2] FIG. 2 is a schematic diagram of the knitted fabric having the rope pattern shown in FIG. [Diagram 3] FIG. 3 is a first knitting process diagram of the knitting method of the rope pattern shown in the embodiment. [Figure 4] FIG. 4 is a second knitting process diagram following FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, an example of an embodiment of a knitted fabric having a rope pattern and a knitting method of a rope pattern will be described with reference to the drawings.

[0018] <Embodiment 1> <Knitted fabric with rope pattern> The knitted fabric having a rope pattern of this example shown in the photograph of Figure 1 comprises a base knitted fabric portion and a rope pattern arranged within the knitting width of the base knitted fabric portion. The base knitted fabric portion of this example has a rib structure, but may also have a plain stitch structure. The knitted fabric having a rope pattern may be a single-layer knitted fabric or a tubular knitted fabric. Hereinafter, the "knitted fabric having a rope pattern" will be referred to simply as "knitted fabric".

[0019] As shown in the schematic diagram of FIG. 2, the base knitted fabric portion 2 of the knitted fabric 1 includes a first base portion 21 and a second base portion 22 that sandwich a rope pattern 3 in the knitting width direction of the base knitted fabric portion 2. On the other hand, the rope pattern 3 includes a first rope pattern portion 31 and a second rope pattern portion 32. The first rope pattern portion 31 and the second rope pattern portion 32 extend toward the wale direction of the base knitted fabric portion 2 while repeatedly intersecting with the knitting width direction of the base knitted fabric portion 2. In FIG. 2, the first rope pattern portion 31 is shown by hatching at 135°, and the second rope pattern portion 32 is shown by hatching at 45°. The wale directions of the first rope pattern portion 31 and the second rope pattern portion 32 are indicated by thick arrows or dashed arrows. Both base portions 21 and 22 are not hatched.

[0020] The rope pattern 3 has an exchange region 30 where the first rope pattern portion 31 and the second rope pattern portion 32 cross each other, and the positions of the two rope pattern portions 31, 32 in the knitting width direction are exchanged. The part of the first rope pattern portion 31 that corresponds to the exchange region 30 is the first exchange portion 3A. In FIG. 2, the part divided by two dotted chain lines extending diagonally downward to the right is the first exchange portion 3A. On the other hand, the part of the second rope pattern portion 32 that corresponds to the exchange region 30 is the second exchange portion 3B. In FIG. 2, the part divided by two dotted chain lines extending diagonally upward to the right is the second exchange portion 3B. In this example, the first exchange portion 3A is disposed on the back side of the second exchange portion 3B. The knitting width direction of the first exchange portion 3A is a direction that intersects with the wale direction of the first exchange portion 3A indicated by the dashed arrow. On the other hand, the knitting width direction of the second replacement portion 3B is a direction intersecting with the wale direction of the second replacement portion 3B indicated by the thick arrow.

[0021] Both ends in the knitting width direction of the first replacement portion 3A indicated by the hollow arrow are not connected to the first base portion 21, the second replacement portion 3B, or the second base portion 22. In addition, both ends in the knitting width direction of the second replacement portion 3B indicated by the filled arrow are not connected to the first base portion 21, the first replacement portion 3A, or the second base portion 22. The first rope pattern portion 31 and the second rope pattern portion 32, except for the first replacement portion 3A and the second replacement portion 3B, are connected to the base knitted fabric portion 2 in the knitting width direction of the base knitted fabric portion 2. The first rope pattern portion 31 and the second rope pattern portion 32 are also connected to each other except for the first replacement portion 3A and the second replacement portion 3B.

[0022] Each of the first and second replacement sections 3A and 3B is made up of a plurality of stitch rows continuing in the wale direction. The number of the plurality of stitch rows is greater than the number of stitch rows continuing in the wale direction of the base knitted fabric section 2 at the intersection of the first and second replacement sections 3A and 3B. The number of stitches in the knitting width direction of each stitch row in the replacement sections 3A and 3B in this example is the same. The number of stitch rows continuing in the wale direction in the first replacement section 3A is preferably 50% to 120% of the number of stitches aligned in the knitting width direction in the first replacement section 3A. In addition, the number of stitch rows continuing in the wale direction in the second replacement section 3B is preferably 50% to 120% of the number of stitches aligned in the knitting width direction in the second replacement section 3B. For example, if the number of stitches aligned in the knitting width direction is 10, the number of stitch rows aligned in the wale direction is preferably 5 to 12. The number of stitches in the knitting width direction of the first replacement section 3A is preferably 4 or more. There is no upper limit to the number of stitches, and it may be, for example, 6 stitches or more, 8 stitches or more, or 12 stitches or more. The number of stitches is determined according to the design of the knitted fabric 1.

[0023] The number of stitches in the knitting width direction of the first replacement section 3A and the number of stitches in the knitting width direction of the second replacement section 3B may be the same or different. Also, the number of stitch rows of the first replacement section 3A may be the same as the number of stitch rows of the second replacement section 3B or may be different.

[0024] In the knitted fabric 1 of this example, the first exchange section 3A and the second exchange section 3B are formed by increasing the number of knitting courses in the exchange region 30. Therefore, the rope pattern 3 is three-dimensional and has an excellent appearance. In addition, in the knitted fabric 1 of this example, both ends in the knitting width direction of the first exchange section 3A are not connected to anywhere, and both ends in the knitting width direction of the second exchange section 3B are not connected to anywhere. Therefore, even if the knitted fabric 1 is pulled in the knitting width direction, yarn breakage is unlikely to occur in the exchange region 30.

[0025] <How to knit a rope pattern> The knitted fabric 1 of this example is knitted by a flat knitting machine. The flat knitting machine has a front needle bed and a back needle bed that face each other. Hereinafter, the front needle bed is referred to as FB and the back needle bed is referred to as BB. The FB and BB are configured to be rackable relative to each other. In this example, a knitting example using a two-bed flat knitting machine in which the BB is configured to be rackable will be described. The flat knitting machine used for knitting may be a four-bed flat knitting machine.

[0026] Next, an example of a method for knitting a rope pattern using a flat knitting machine will be described based on the knitting process diagrams of Figures 3 and 4. The "S+number" in the left column of Figures 3 and 4 indicates the knitting process number. The right column shows the state of stitch retention in each knitting process. In Figures 3 and 4, FB and BB are shown by thick horizontal lines. Also, stitch rows consisting of stitches retained at FB and BB are shown by hatched squares.

[0027] S0 in Fig. 3 shows a state in which the knitted fabric 1 knitted up to just before the bottom end of the replacement area 30 in Fig. 2 is engaged with the FB. The knitted fabric 1 in this example is divided into a first base stitch row 4, a first stitch row 5, a second stitch row 6, and a second base stitch row 7, in order from the left on the page. The first base stitch row 4, the first stitch row 5, the second stitch row 6, and the second base stitch row 7 are stitch rows that respectively constitute the first base portion 21, the first rope pattern portion 31, the second rope pattern portion 32, and the second base portion 22 in Fig. 2.

[0028] A vertical line is shown at the boundary between two adjacent stitch rows in the knitting width direction. The stitches sandwiching each boundary are connected via a sinker loop. For example, the end stitch on the right side of the first base stitch row 4 and the end stitch on the left side of the first stitch row 5 are connected by a sinker loop. If the positions of the first stitch row 5 and the second stitch row 6 are interchanged from this state, the sinker loop connecting each boundary may break. In this example, the number of stitches in the knitting width direction of the first stitch row 5 is 12, and the number of stitches in the knitting width direction of the second stitch row 6 is also 12. If the positions of such first stitch row 5 and second stitch row 6 are interchanged, the sinker loop at the boundary will break. Therefore, in this example, the knitting method of the rope pattern of the present invention shown below is carried out.

[0029] In S1, the first base stitch row 4 is moved from FB to BB (corresponding to step A1). The first base stitch row 4 and the first stitch row 5 are connected by a sinker loop 8a. The sinker loop 8a is a knitting yarn that connects the end stitch on the right side of the first base stitch row 4 and the end stitch on the left side of the first stitch row 5.

[0030] In S2, the BB is racked one pitch to the left, and then a new first stitch row 5N is knitted in the wale direction of the first stitch row 5 (part of process A2). The left direction is the first direction 4D (see S0) in which the first base stitch row 4 is arranged among the racking directions. This knitting of S2 is repeated multiple times. In this example, the knitting of S2 is repeated nine times. Here, in this example, the BB is racked two pitches in three S2s out of the nine S2s. Therefore, after nine S2s are repeated, the BB is racked 12 pitches to the left.

[0031] S3 shows a state in which the first replacement section 3A is completed by knitting a plurality of new first stitch rows 5N. The last knitted first stitch row 50 is a part of the first replacement section 3A. The left end of the first stitch row 5 is connected to the first base stitch row 4 via a sinker loop 8a. The right end of the first stitch row 5 is connected to the second stitch row 6 via a sinker loop 8b.

[0032] As shown in S3, the first stitch row 5 is connected to the first base stitch row 4 via the sinker loop 8a, so that the first replacement section 3A is pulled to the left. By pulling the first replacement section 3A to the left, the first replacement section 3A does not remain below the needle bed. In normal knitting, the newly knitted knitted fabric section is lowered below the needle bed by the action of the pull-down device or the pushing of the sinker mechanism. However, if only the new first stitch row 5N is increased, the first base stitch row 4 and the second stitch row 6 connected to the first stitch row 5 prevent the new first stitch row 5N from being sent out downward. As a result, the new first stitch row 5N remains below the needle bed, and the knitting of the first stitch row 5N becomes unstable, for example, if there is no movable sinker. When the number of times S2 is repeated is small, such a problem is unlikely to occur. Therefore, when the number of times S2 is repeated is small, the movement of S1 and the racking at S2 are not necessary.

[0033] In S4, the last first stitch row 50 is moved to BB. Twelve empty needles are arranged between the first base stitch row 4 and the last first stitch row 50. In the following S5, BB is racked to the right (part of process C). The right direction is the second direction 7D (see S0) in which the second base stitch row 7 is arranged among the racking directions. The racking amount is 12 pitches, which is the same as the knitting width of the first stitch row 50. Therefore, the first stitch row 50 is arranged in a position facing the second stitch row 6 in the front-rear direction.

[0034] In S6 of Fig. 4, the second base stitch row 7 is moved from FB to BB (corresponding to step B1). In this S6, only the last knitted first stitch row 50 of the first replacement section 3A is shown. The second base stitch row 7 and the second stitch row 6 are connected by a sinker loop 8c. The sinker loop 8c is a knitting yarn that connects the end stitch on the left side of the second base stitch row 7 and the end stitch on the right side of the second stitch row 6.

[0035] In S7, the BB is racked one pitch to the right (second direction 7D), and then a new second stitch row 6N is knitted in the wale direction of the second stitch row 6 (part of process B2). This knitting of S7 is repeated multiple times (the remainder of process B2). In this example, the knitting of S7 is repeated nine times. Here, in this example, of the nine S7s, the BB is racked two pitches in three S7s. As a result, the BB is racked 12 pitches to the right.

[0036] In this example, the number of courses X of the newly knitted second stitch row 6N is the same as the number of courses Y of the newly knitted first stitch row 5N, but the number of courses X may be more or less than the number of courses Y.

[0037] S8 shows a state in which the second replacement section 3B is completed by knitting a plurality of new second stitch rows 6N. The last knitted second stitch row 60 is a part of the second replacement section 3B. By knitting the new second stitch row 6N while racking the BB in the second direction 7D, the second replacement section 3B does not remain below the needle bed.

[0038] As shown in S8, by repeating racking of the BB to the right, a blank area consisting of 12 empty needles is arranged at the position of the BB facing the second replacement part 3B that is engaged with the FB. The racking of the BB to the right is also a part of the process C. In S9, the second replacement part 3B is moved to the blank area (the remainder of the process C). As a result, the replacement of the first replacement part 3A and the second replacement part 3B is completed. As shown in S9, the first base part 21, the second replacement part 3B, the first replacement part 3A, and the second base part 22 are separated. Therefore, even though the number of stitches in the knitting width direction of each of the first replacement part 3A and the second replacement part 3B is 12, no yarn breakage occurs when the first replacement part 3A and the second replacement part 3B are replaced.

[0039] In S10, the BB is racked leftward to eliminate the misalignment between the FB and the BB, and the first base portion 21, the second replacement portion 3B, the first replacement portion 3A, and the second base portion 22 are moved from the BB to the FB. After S10, a row of stitches continuing in the wale direction of all stitches held by the FB is knitted, thereby knitting a portion in the wale direction above the replacement area 30 in Fig. 2. As a result, the first base portion 21, the second rope pattern portion 32, the first rope pattern portion 31, and the second base portion 22 are connected in the knitting width direction.

[0040] In the above embodiment, as shown in Fig. 2, an example has been described in which the first replacement section 3A is arranged on the rear side of the second replacement section 3B. In contrast, the second replacement section 3B can also be arranged on the rear side of the first replacement section 3A. In that case, a knitting process in which the knitting process diagrams shown in Figs. 3 and 4 are reversed from left to right may be performed. Of the first replacement section 3A and the second replacement section 3B, the replacement section arranged on the rear side is knitted before the replacement section arranged on the front side.
