Description

Technical Field

[0001] The present invention relates to a method for knitting a knitted fabric having a first base and a second base that are continuous in the longitudinal direction. Background Technology

[0002] Patent Document 1 discloses a technique for placing a padding yarn in the knit width direction of a base knitted fabric portion. In this technique, a portion of the loops in the base knitted fabric portion are half-stitched, and a padding yarn is inserted between the half-stitched loop and a new loop knitted by the half-stitch. If the base knitted fabric portion is excessively stretched, it is difficult for the shape of the base knitted fabric portion to return to its pre-stretch state. If the padding yarn is a non-elastic yarn, the elongation of the base knitted fabric portion in the knit width direction is suppressed.

[0004] [Patent Document 1] Japanese Patent Application Publication No. 2000-96398 Summary of the Invention

[0005] [The problem the invention aims to solve]

[0006] In knitted fabrics, there exist instances where a first base and a second base, serving different functions, are continuous in the warp direction. In such knitted fabrics, there is a need to prevent the boundary between the first and second bases from elongating. The technology in Patent Document 1 fails to meet this need. Particularly when the first and second bases have different weaves, the technology in Patent Document 1 may not be able to sufficiently suppress the elongation of the aforementioned boundary.

[0007] One of the objectives of this invention is to provide a weaving method that makes it difficult for the boundary between the continuous first base and the second base in the longitudinal direction to elongate.

[0008] [Methods used to solve problems]

[0009] <1> The knitting method of the present invention uses a flat knitting machine to knit a fabric having a first base and a second base that is connected to the end portion in the longitudinal direction of the first base, wherein...

[0010] The weaving method comprises:

[0011] Step A, after weaving the first base layer, divides the coils within a specified range of the terminal portion into three or more groups; and

[0012] Process B, repeat processes B1 and B2 until there are no more groups (51, 52, 53, 54) to select.

[0013] In step B1, group X is selected from the three or more groups.

[0014] In step B2, a reinforcing coil is formed that overlaps with the coil in group X.

[0015] The configuration range of the coils in each of the three or more groups overlaps with the configuration range of the coils in other groups in the braiding width direction.

[0016] Here, the defined scope of the terminal section can be a part of the terminal section or the entire terminal section. Furthermore, the reinforcing coil can overlap with all the coils of group X, or it can overlap with a part of the coils of group X.

[0017] In process A, the coils of each group are grouped such that their arrangement overlaps with that of other groups in the braiding width direction. As a result, at least a portion of each group has a section sandwiching coils from other groups between two coils arranged in the braiding width direction within that group. For example, when the terminal section is divided into a first group, a second group, and a third group, as shown in Example 1 below, the coils of the first group, the second group, and the third group can be arranged sequentially. As shown in Example 2 below, each group can also include portions where the coils are adjacent to each other. As shown in Example 3 below, the coils of each group can also be arranged irregularly. Furthermore, in Examples 1 to 3 below, “○” represents the coil of the first group, “×” represents the coil of the second group, and “△” represents the coil of the third group.

[0018] ·Example 1…○×△○×△○×△○×△

[0019] ·Example 2…○○××△△○○××△△

[0020] ·Example 3…○×△○○××△△○×△

[0021] In the above weaving method, the number of groups is consistent with the number of repetitions of steps B1 and B2. The number of groups is, for example, 3 or more but less than 6. The number of loops in each group can be the same or different.

[0022] <2> In the above manner <1> In the knitting methods of knitted fabrics, it can also be:

[0023] The number of groups of three or more is N.

[0024] Each of the three or more groups consists of coils spaced N-1 times apart.

[0025] Here, N is a natural number greater than 3.

[0026] As described above <2> A specific example illustrates the case where the coils at the end of a first coil column consisting of 12 coils are divided into three groups. In this case, each group consists of coils spaced two coils apart. Specifically, the first group consists of the first, fourth, seventh, and tenth coils counted from one end in the braid width direction at the end of the coil. The second group consists of the second, fifth, eighth, and eleventh coils. The third group consists of the third, sixth, ninth, and twelfth coils.

[0027] <3> In the above manner <1> or <2> In the knitting methods of knitted fabrics, it can also be:

[0028] The process B2 includes:

[0029] Step X involves weaving the reinforcing coil drawn from the coil of group X by picking out half a mesh; and

[0030] In step Y, the coil of group X and the reinforcing coil are overlapped.

[0031] Picking up half a stitch is a well-known knitting method (see Patent Document 1, etc.). In picking up half a stitch, the loop Q of the needle P1 hooked on the needle bed P is moved towards the needle R1 of the needle bed R, and a loop S leading from loop Q is formed on the needle P1. The loop S leading from loop Q is connected to loop Q. In this invention, the reinforcing loop is equivalent to loop S, and the loop of group X is equivalent to loop Q.

[0032] <4> In the above manner <3> In the knitting methods of knitted fabrics, it can also be:

[0033] A process Z is provided after process X and before process Y, wherein a padding yarn is arranged between the coil of group X and the reinforcing coil.

[0034] The padding yarn is the thread sandwiched between the coils distributed to the front and rear needle beds of the flat knitting machine (see Patent Document 1, etc.). In the above manner... <4> In the middle, the padding yarn is sandwiched between the reinforcing coil and the coil of group X.

[0035] <5> In the above manner <1> or <2> In the knitting methods of knitted fabrics, it can also be:

[0036] In step B2, the reinforcing coil is formed by looped coils that overlap with the coils of group X using loop weaving.

[0037] <6> In the above manner <1> to <5> In any of the knitting methods for knitted fabrics, it can also be,

[0038] The reinforcing loop is woven using the knitting yarn used in the weaving of the first base.

[0039] [Invention Effects]

[0040] According to the knitting method of the present invention, elongation of the boundary between the first base and the second base in the knitted fabric can be effectively suppressed. The reinforcing loop only overlaps with the end portion of the first base, making the reinforcing loop inconspicuous. In addition, the boundary is less likely to thicken due to the reinforcing loop.

[0041] According to the above method <2> The weaving method involves regularly arranged reinforcing loops overlapping the end portion. Therefore, uneven stretching at the boundary along the weave width is less likely to occur. Furthermore, the aesthetics of the boundary are improved.

[0042] According to the above method <3> The knitting method forms a reinforcing loop drawn from the loop at the end of the first base portion. This reinforcing loop is difficult to move relative to the loop at the end portion. Therefore, in a knitted fabric with such a reinforcing loop, the aforementioned boundary is difficult to elongate.

[0043] According to the above method <4> The knitting method yields a knitted fabric with padding yarns placed at the aforementioned boundaries. The padding yarns suppress elongation in the knit width direction of the knitted fabric at the aforementioned boundaries. Therefore, in knitted fabrics with padding yarns at the aforementioned boundaries, the boundaries are less prone to elongation.

[0044] According to the above method <5> The knitting method allows for the weaving of fabrics with limited stretching boundaries using fewer steps.

[0045] In the above manner <6> In this knitting method, there is no need for a yarn feeder for knitting reinforcing loops. Furthermore, in the knitted fabric obtained by this method, there is no need for yarn cutting and knotting that accompanies yarn switching, thus increasing fabric productivity.

[0064] Hereinafter, a knitting method for a knitted fabric according to an embodiment will be described based on the accompanying drawings.

[0065] <Implementation Method 1>

[0066] Figure 1 A knitted sweater is shown as an example of knitted fabric 1 as described in Embodiment 1. The sweater has: a body piece 2 having sleeves; and a collar 3 connected to the body piece 2 in a seamless knitting manner. The body piece 2 has a front body piece 2F and a back body piece 2B connected in a tubular shape. The body piece 2 is knitted from the hem toward the collar 3. The collar 3 has a front neckline 3F that is continuous with the end portion of the front body piece 2F in the longitudinal direction and a back neckline 3B that is continuous with the end portion of the back body piece 2B in the longitudinal direction. The front neckline 3F and the back neckline 3B are connected in a tubular shape. In this example, the weave of the body piece 2 and the weave of the collar 3 are different.

[0067] The neckline of a knitted sweater forming the collar 3 sometimes gradually expands after repeated wearing due to differences in the raw materials of the knitting yarn. Therefore, it is preferable to suppress the elongation of the boundary 4 between the body piece 2 and the collar 3. In this example, the knitted sweater is knitted using the knitting method of the present invention, thereby suppressing the elongation of the boundary 4 between the back body piece 2B and the back collar 3B. The back body piece 2B and the back collar 3B correspond to the first base 5 and the second base 6 in the knitting method of the present invention, respectively.

[0068] based on Figure 2 as well as Figure 3An example of the knitting steps for the boundary 4 between the first base 5 and the second base 6 will be described. The flat knitting machine used is a 4-bed flat knitting machine. A 4-bed flat knitting machine has 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, lower back needle bed, upper front needle bed, and upper back needle bed will be referred to as FD, BD, FU, and BU, respectively. FD and BD are opposite each other. FU, located above FD, and BU, located above BD, are opposite each other. FD and FU are the first needle beds, and BD and BU are the second needle beds. This flat knitting machine has a lateral movement mechanism (not shown), allowing FD, FU, BD, and BU to move laterally relative to each other. Alternatively, a 2-bed flat knitting machine may be used instead of the one shown in this example.

[0069] Figure 2 , 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 solid circles in the right column indicate the needles FD, BD, FU, and BU. The capital letters outside the column indicate the needle positions. The circular and teardrop marks in the right column indicate loops, and the inverted triangle mark indicates the yarn feeder 9. Parts related to the knitting action of each knitting process are indicated by thick lines.

[0070] exist Figure 2 In step S0, body piece 2 is shown (refer to...) Figure 1 The knitting is finished. Body piece 2 is knitted from knitting yarn 9Y supplied from yarn feeder 9. The loops of the front body piece 2F are hooked onto needles A to L of FD. The loops at the end of the back body piece 2B, that is, the loops at the end of the first base 5 5 5, are hooked onto needles A to L of BD.

[0071] In step S0, the coils of the terminal section 50 are divided into three or more groups, in this example, into group 51, group 52, group 53, and group 54 (process A). Since there are four groups, each group 51, 52, 53, and 54 consists of coils spaced three times apart. That is, the spacing between adjacent coils in the knitting width direction within each group 51, 52, 53, and 54 is the spacing of three coils from other groups arranged between the adjacent coils. Specifically, group 51 consists of coils from needles D, H, and L of the BD knitting machine. Group 52 consists of coils from needles C, G, and K of the BD knitting machine. Group 53 consists of coils from needles B, F, and J of the BD knitting machine. Group 54 consists of coils from needles A, E, and I of the BD knitting machine. This grouping is a conceptual process executed within the computer of the flat knitting machine.

[0072] In this example, the entire end portion 50 of the back panel 2B is divided into multiple groups. In contrast, a portion of the end portion 50, such as the middle portion in the knit width direction of the back panel 2B, or for example, a portion equivalent to one-third of the entire portion, may also be divided into multiple groups.

[0073] In step S1, group X (the first operation B1) is selected from groups 51, 52, 53, and 54. In this example, the first group 51 is selected as group X. This selection is also a conceptual operation, performed within the computer of the flat knitting machine.

[0074] In step S1, the yarn feeder 9 is moved to the right, and a reinforcing loop 7 is knitted from the loops of the first group 51 by picking up half a stitch (step X in the first step B2). By picking up half a stitch, the loops of the first group 51 move toward the needles D, H, and L of FU, forming the reinforcing loop 7 on the needles D, H, and L of BD. The reinforcing loop 7 is knitted using the knitting yarn 9Y used in the knitting of the first base 5, thereby eliminating the time required for changing the knitting yarn. The reinforcing loop 7 can also be knitted using knitting yarn supplied from a different yarn feeder than the yarn feeder 9, unlike in this example.

[0075] Alternatively, unlike this example, half-throwing may not be applied to all coils in the first group 51. For example, half-throwing may be applied to more than 70% of the coils in the first group 51. This is also the case for the second group 52, the third group 53, and the fourth group 54, which will be described later.

[0076] In step S2, the yarn feeder 9 is moved to the left, and the knitting yarn 9Y is positioned between the first group 51 of FU and the reinforcing loop 7 of BD (step Z in the first step B2). The knitting yarn 9Y functions as a padding yarn 8. The padding yarn 8 can also be supplied from a different yarn feeder than the yarn feeder 9.

[0077] In step S2, the first group 51 loops and the reinforcing loop 7 are further overlapped (step Y in the first step B2). In this example, the first group 51 loop hooked on FU is overlapped with the reinforcing loop 7 hooked on BD. The first group 51 loops and the reinforcing loop 7 that form the overlapping loops are paired loops in a half-stitch. For example, the loop that moves from needle D of BD to needle D of FU by a half-stitch in step S1 overlaps with the reinforcing loop 7 formed on needle D of BD.

[0078] Then, steps B1 and B2 are repeated until no more groups can be selected (step B). Specifically, in step S3, the second group 52 is selected as group X (second step B1), and half-mot is picked up when the yarn feeder 9 moves to the right (step X in second step B2). In step S4, the padding yarn 8 is arranged when the yarn feeder 9 moves to the left (step Z in second step B2), and the loops of group X and the reinforcing loops 7 overlap (step Y in second step B2).

[0079] exist Figure 3In steps S5 and S6, the third group 53 is selected, and the third processes B1 and B2 are performed. Then, in steps S7 and S8, the fourth group 54 is selected, and the fourth processes B1 and B2 are performed.

[0080] After step S8, the back collar 3B is knitted by continuing to knit in the longitudinal direction at the end portion 50 of the back body piece 2B. Figure 1 ), and the front collar 3F is woven in the longitudinal direction at the end of the front piece 2F. Figure 1 By weaving the back neck 3B, i.e. the second base 6, the overlapping loops formed by the loops of the terminal portion 50 and the reinforcing loops 7 are fixed. The reinforcing loops 7 are difficult to move relative to the loops of the terminal portion 50, and the padding yarn 8 sandwiched between the loops of the terminal portion 50 and the reinforcing loops 7 is also difficult to move.

[0081] Figure 4 This is a schematic diagram showing the configuration of the padding yarn 8 in the terminal portion 50 of the first base 5. The lower side of the diagram shows the inner side of the knitted sweater, and the upper side shows the outer side of the knitted sweater. Figure 4 The roughly rectangular markings indicate the coil (i.e., any one of the coils in groups 51, 52, 53, and 54) or reinforcing coil 7 of the terminal portion 50 of the first base 5. Two parallel lines extending longitudinally indicate that the coil of the terminal portion 50 is connected to the reinforcing coil 7 by a half-mesh connection. Figure 4 In the middle section, the coil of the terminal part 50 and the reinforcing coil 7 are separate, but actually overlap. The thick line represents the padding yarn 8.

[0082] like Figure 4 As shown, reinforcing coils 7 overlap each coil in the terminal section 50. Therefore, the elongation of the terminal section 50 in the braid width direction is suppressed. Figure 1 The elongation of the boundary 4 of the knitted fabric 1 is shown. Particularly in this example, all the reinforcing loops 7 are connected by a transition yarn composed of knitting yarn 9Y, thus the reinforcing loops 7 on one side connected by the transition yarn constrain each other's movement. This is one reason for suppressing the elongation of the boundary 4. Furthermore, by arranging four padding yarns 8 at the end portion 50, the elongation of the end portion 50, i.e., the elongation of the boundary 4, is further suppressed.

[0083] like Figure 4 As shown, in this example's knitting method, the reinforcing loop 7 is only arranged at the end portion 50, and the reinforcing loop 7 is inconspicuous. The end portion 50 is not excessively thick in the thickness direction of the knitted fabric 1. In addition, the padding yarn 8 is arranged on the inside of the knitted sweater, making it difficult to see from the outside of the knitted sweater. Therefore, the knitted fabric 1 in this example has good aesthetics and excellent wearing comfort.

[0084] Having Figure 4In the knitted fabric 1 of the terminal portion 50 shown, even though the boundary 4 extends in the knit width direction, wrinkles are almost impossible to form in the portion near the boundary 4 in the first base 5. The reason wrinkles can form in this portion is that the first base 5, which is in a state of sandwiching each pad yarn 8 disposed in the terminal portion 50, shifts from its initial position, and the shifted first base 5 does not return to its initial position. The initial position refers to the position of the first base 5 relative to the pad yarn 8 during knitting. In this example, the reason why the position of the first base 5 is difficult to shift relative to the pad yarn 8 is presumably because the pad yarn 8 and the first base 5 are in contact with each other on the inside of the knitted sweater for a specified length. The length of each pad yarn 8 on the inside of the knitted sweater depends on the spacing of adjacent loops in each group 51, 52, 53, 54 (hereinafter, this spacing is referred to as spacing W). Therefore, spacing W is considered an important factor for suppressing the positional shift of the first base 5 relative to the pad yarn 8.

[0085] Experimental Examples

[0086] In the experimental example, in order to investigate the effect of the above-mentioned interval W on the formation of folds, the following knitted fabrics α and β were made.

[0087] In the production of knitted fabric α, in Figure 2 In step S0, the terminal portion 50 is divided into three groups, and steps S1 and S2 are performed on each group. The interval W in each group is the interval between two loops. For example, in the first group, loops B1 of the second group and loops C1 of the third group are arranged between adjacent loops A1 and A2. The number of padding yarns 8 arranged in the terminal portion 50 of the knitted fabric α is 3. In the knitted fabric α, the boundary 4 between the first base 5 and the second base 6 is difficult to stretch to the same extent as the knitted fabric 1 of Embodiment 1. In addition, in the knitted fabric α, even if the boundary 4 is stretched, there are almost no wrinkles in the part near the boundary 4 of the first base 5.

[0088] In the production of knitted fabric β, in Figure 2 In step S0, the terminal portion 50 is divided into two groups. In this case, the interval W in each group is an interval equal to the amount of one loop. Steps S1 and S2 are then performed on each group. In the knitted fabric β, the boundary 4 between the first base 5 and the second base 6 is difficult to elongate. However, in the knitted fabric β, if the boundary 4 elongates, wrinkles form in the portion near the boundary 4 of the first base 5, and these wrinkles persist. These wrinkles detract from the aesthetics of the knitted fabric β.

[0089] According to the results of the test examples, in order to suppress the positional shift of the first base 5, which is the cause of wrinkle formation, it is necessary to have a spacing of two loops or more (hereinafter, this spacing is referred to as the specified spacing) between each group of the terminal portion 50. However, even if there are portions in each group that are smaller than the specified spacing, the positional shift of the first base 5 can be suppressed as long as the number of such portions is small. The ratio Nb / Na of the number Na of portions sandwiched by adjacent loops in each group (hereinafter referred to as first portions) to the number Nb of portions having the specified spacing (hereinafter referred to as second portions) is 0.5 or more. That is, if more than half of the first portions are second portions, the positional shift of the first base 5 can be suppressed. When the number Nb of second portions is smaller than the number Na of first portions, it is preferable that Nb second portions are distributed in the knitting width direction. The higher the ratio Nb / Na, the more preferred. The ratio Nb / Na can be, for example, 0.8 or more or 0.9 or more. As with the knitted fabric 1 of Embodiment 1 and the knitted fabric α of the test example, the most preferred ratio Nb / Na is 1.0.

[0090] <Implementation Method 2>

[0091] In Embodiment 2, a weaving example is described where the reinforcing loop 7 is woven using half-mesh weaving but without padding yarn 8. In this description, the method of Embodiment 1 is used... Figure 2 , Figure 3 .

[0092] In this example, Figure 2 After step S1, in step S2, the yarn feeder 9 is not moved, but the coils of the first group 51 are overlapped with the reinforcing coil 7. In step S3, the yarn feeder 9 is moved to the left (opposite to the direction of movement shown in the figure) to perform half-rolling. In step S4, the yarn feeder 9 is not moved, but the coils of the second group 52 are overlapped with the reinforcing coil 7. Figure 3 After step S5, in step S6, the yarn feeder 9 is not moved, but the coils of the third group 53 are overlapped with the reinforcing coil 7. In step S7, the yarn feeder 9 is moved to the left (opposite to the direction of movement shown in the figure) to pick up half a thread. In step S8, the yarn feeder 9 is not moved, but the coils of the fourth group 54 are overlapped with the reinforcing coil 7.

[0093] In this example, a reinforcing coil 7 is arranged along the entire length of the terminal portion 50. Therefore, the elongation of the terminal portion 50 can be effectively suppressed.

[0094] <Implementation Method 3>

[0095] In implementation method 3, based on Figure 5 This section illustrates an example of forming a reinforcing coil by tucking the coil together. Figure 5 Observation methods and Figure 2 , Figure 3 same. Figure 5 The V-shaped mark in the figure indicates a coiled coil.

[0096] Figure 5 Step S0 and Figure 2 Step S0 is the same. In step S1, the yarn feeder 9 moves to the right to coil the coils of the first group 51. Through this coiling, the reinforcing coil 70 formed by the coiled coils overlaps with the coils of the first group 51. In step S2, the yarn feeder 9 moves to the left to coil the coils of the second group 52. In step S3, the yarn feeder 9 moves to the right to coil the coils of the third group 53. In step S4, the yarn feeder 9 moves to the left to coil the coils of the fourth group 54.

[0097] pass Figure 5 The weave shown features reinforcing loops 70 arranged along the entire length of the terminal portion 50. As a result, the transition yarns connecting multiple loops have increased contact opportunities with each other, effectively suppressing the elongation of the terminal portion 50. In each loop of the terminal portion 50, the knitting yarn 9Y is not wrapped but only overlapped with the reinforcing loops 70, so the terminal portion 50 does not become too thick.

[0098] Figure 5 The number of processes is the same as the number of groups in the terminal section 50, which is less than the number of processes in Embodiment 1. Therefore, according to the knitting method of this example using loops, it is possible to manufacture the knitted fabric 1, which is difficult to stretch at the boundary 4, with good productivity.
