Description

[Technical field]

[0001] The present invention relates to a method for knitting a knitted fabric that connects the wale-wise end portion of a first knitted fabric section and the wale-wise end portion of a second knitted fabric section, and to a knitted fabric in which the terminal ends of the first knitted fabric section and the second knitted fabric section are joined together. [Background technology]

[0002] A flat knitting machine equipped with a first needle bed and a second needle bed is used to join the wale direction end of a first knitted fabric part held on the first needle bed and the wale direction end of a second knitted fabric part held on the second needle bed. For example, Patent Document 1 discloses a knitting method for joining a first knitted fabric part and a second knitted fabric part by a bind-off process. The bind-off process is a process in which two adjacent stitches are overlapped to form an overlapping stitch, and a new stitch is knitted on the overlapping stitch, and this process is repeated. Fraying of the stitches is suppressed at the joint formed by the bind-off process. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2011 / 018929 Summary of the Invention [Problem to be solved by the invention]

[0004] The joints formed by the bind-off process have excellent appearance and elasticity. However, each stitch must be processed one by one, and the number of steps required to form the joints is very large. In particular, when the length to be joined is long, the time required to form the joints becomes very long.

[0005] An object of the present invention is to provide a knitting method for a knitted fabric that can connect a first knitted fabric portion and a second knitted fabric portion more easily than by a bind-off process. An object of the present invention is to provide a knitted fabric that is produced with high productivity while having a joint portion. [Means for solving the problem]

[0006] <1> The knitting method of the knitted fabric of the present invention includes the steps of: Using a flat knitting machine equipped with a first needle bed and a second needle bed, A knitting method for a knitted fabric that connects a first stitch row of a first knitted fabric portion held on the first needle bed and a second stitch row of a second knitted fabric portion held on the second needle bed, A process A of dividing a plurality of stitches constituting the first stitch row into n groups and dividing a plurality of stitches constituting the second stitch row into m groups; A step B repeating the steps B1 and B2 until there are no more selectable groups; In the step B1, one group X is selected from the n groups, and one group Y is selected from the m groups; In the step B2, a stitch following each stitch of the group X in the wale direction and a stitch following each stitch of the group Y in the wale direction are knitted using a heat fusible yarn; The numbers of groups m and n in the step A are the same and are 2 or more and 6 or less.

[0007] In the knitting method of the above knitted fabric, the number of groups and the number of repetitions of steps B1 and B2 are the same. For example, if the first knitting row and the second knitting row are each divided into three groups, in the first step B1, one of the three groups of the first knitting row and one of the three groups of the second knitting row are selected, and the first step B2 is performed. In the second step B1, group X and group Y are selected from the groups not selected in the first step B1, and the second step B2 is performed. Then, in the third step B1, the remaining group of the first knitting row and the remaining group of the second knitting row are selected, and the third step B2 is performed.

[0008] The number of stitches in each group constituting the first stitch row and the number of stitches in each group constituting the second stitch row may be the same or different. For example, when the first stitch row consisting of 12 stitches is divided into two groups, the number of stitches in the first group may be 6 stitches and the number of stitches in the second group may also be 6 stitches, or the number of stitches in the first group may be 4 stitches and the number of stitches in the second group may be 8 stitches. The number of stitches in group X and the number of stitches in group Y may also be the same or different.

[0009] In the process A, it is preferable to group the stitches so that the arrangement range of the stitches of each group overlaps the arrangement range of the stitches of the other groups in the knitting width direction. As a result, each group in the first stitch row and the second stitch row has a portion where the stitches of the other groups are sandwiched between two stitches arranged in the knitting width direction in each group. For example, when the first stitch row is divided into the first group and the second group, as shown in Example 1 below, the stitches of the first group and the stitches of the second group are arranged alternately in the knitting width direction. As shown in Example 2 below, the first group may include a portion where the stitches constituting the first group are adjacent to each other, and the second group may include a portion where the stitches constituting the second group are adjacent to each other. As shown in Example 3 below, the stitches of the first group and the stitches of the second group may be arranged irregularly. In Examples 1 to 3 below, "○" indicates the stitches of the first group, and "×" indicates the stitches of the second group. Example 1…○×○×○×○×○×○×○× Example 2…○○××○○××○○×× Example 3…○×○○×○○×○××

[0010] <2> As one embodiment of the knitting method of the knitted fabric of the present invention, In the step B2, all the stitches are purl stitches.

[0011] A purl stitch is a stitch knitted on a needle bed opposite to the needle bed on which the knitted fabric portion is held. For example, when knitting a purl stitch following stitch A of the first knitted fabric portion held on the first needle bed, stitch A is moved to the second needle bed, and then stitch B continuous with stitch A is knitted. This stitch B becomes a purl stitch.

[0012] <3> As one embodiment of the knitting method of the knitted fabric of the present invention, Each of the n groups is made up of stitches every n-1. Each of the m groups may be formed of stitches every m-1 stitches.

[0013] The above form <3> As a specific example, a case will be described where the stitches of a first stitch row consisting of 12 stitches are divided into three groups. In this case, the first group is made up of the 1st, 4th, 7th, and 10th stitches counting from one end of the first stitch row in the knitting width direction. The second group is made up of the 2nd, 5th, 8th, and 11th stitches. The third group is made up of the 3rd, 6th, 9th, and 12th stitches. In this case, in process B2, the stitches following each stitch of group X in the wale direction and the stitches following each stitch of group Y in the wale direction are knitted alternately.

[0014] <4> As one embodiment of the knitting method of the knitted fabric of the present invention, An example of a form includes a step X, which is performed before step A, of knitting at least one of a new first knitting row following the first knitting row in the wale direction, and a new second knitting row following the second knitting row in the wale direction using the heat-sealing yarn.

[0015] <5> The knitted fabric of the present invention is In a knitted fabric having a joint portion that joins end portions of a first knitted fabric portion and a second knitted fabric portion, The joining portion is formed by a plurality of joining stitch rows different from the first knitted portion and the second knitted portion, Each joining stitch row is made up of stitches formed in a part of an end portion of the first knitted fabric section and a part of an end portion of the second knitted fabric section, The knitting yarn constituting each joining stitch row is a heat-sealing yarn, The crossover yarns in each joining stitch row and the crossover yarns in other joining stitch rows are fused in a crossing state, At least a part of the stitches in each joining stitch row and a part of the stitches in another joining stitch row are fused in contact with each other, The crossover yarn spans the first knitted fabric portion and the second knitted fabric portion. Effect of the Invention

[0016] According to the knitting method of the present invention, the first knitted fabric portion and the second knitted fabric portion can be joined with a dramatically fewer number of steps than in the bind-off process. Specifically, the first knitted fabric portion and the second knitted fabric portion can be joined by simply repeating steps B1 and B2 the same number of times as the number of groups.

[0017] By carrying out the knitting method of the knitted fabric of the present invention, the end portions of the first knitted fabric portion and the second knitted fabric portion are connected to each other by a plurality of joining stitch rows formed by heat fusion yarn. By melting a part of the heat fusion yarn by heat treatment such as ironing, the points where the heat fusion yarns contact are fused. The points where the heat fusion yarns contact are points where the heat fusion yarns contact each other and points where the heat fusion yarns contact a non-heat fusion yarn. Examples of points where the heat fusion yarns contact each other include points where the crossover yarns cross each other and points where adjacent stitches overlap each other. By this fusion, the knitted fabric of the present invention having a joining portion that firmly joins the first knitted fabric portion and the second knitted fabric portion is obtained.

[0018] the above <2> According to the knitting method of the knitted fabric, the first knitted fabric portion and the second knitted fabric portion can be connected in a plane. This point will be described in detail in the embodiment.

[0019] the above <3> According to the knitting method of the present invention, the stitches made of the heat fusion yarn connecting the first knitted fabric portion and the second knitted fabric portion are regularly arranged, and as a result, the joining portion between the first knitted fabric portion and the second knitted fabric portion is neatly finished.

[0020] the above <4> According to the knitting method of the knitted fabric, the number of contact points where the heat-fusible yarns come into contact with each other is increased, thereby improving the strength of the joints.

[0021] The knitted fabric of the present invention has excellent productivity even though it has a joint portion, because the multiple joining stitch rows that constitute the joint portion can be knitted in an extremely short time by the knitting method of the knitted fabric of the present invention. [Brief description of the drawings]

[0022] [Figure 1] FIG. 1 is a schematic diagram of a skirt which is a knitted fabric according to an embodiment. [Diagram 2] FIG. 2 is a diagram showing a first knitting process of the knitting method for the knitted fabric according to the embodiment. [Diagram 3] FIG. 3 is a second knitting process diagram following FIG. [Figure 4] FIG. 4 is a loop diagram showing the state of stitches in the vicinity of a joint of the knitted fabric according to the embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, a knitting method of a knitted fabric according to an embodiment and the knitted fabric will be described with reference to the drawings.

[0024] <Embodiment 1> The knitted fabric 9 shown in FIG. 1 is a long skirt knitted horizontally on a flat knitting machine. This knitted fabric 9 has a set-up portion 9S formed at the side edge on the left side of the drawing, and a knitting end portion 9E formed at the side edge on the right side of the drawing. To knit this skirt, first, the set-up portion 9S, which will be the side edge of the skirt, is knitted. Next, a first knitted fabric portion 5 and a second knitted fabric portion 6 branching off from the set-up portion 9S are knitted. Finally, the first knitted fabric portion 5 and the second knitted fabric portion 6 are connected to form the knitting end portion 9E. The knitting method of the knitted fabric of the present invention is applied to the formation of this knitting end portion 9E.

[0025] 2 and 3 are knitting process diagrams showing specific knitting processes for forming the knitting end portion 9E. The flat knitting machine used in this example is a four-bed flat knitting machine. The four-bed flat knitting machine is equipped with a lower front needle bed, a lower rear needle bed, an upper front needle bed, and an upper rear needle bed. Hereinafter, the lower front needle bed, the lower rear needle bed, the upper front needle bed, and the upper rear needle bed are respectively represented 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. In this example, the FD and FU are the second needle beds, and the BD and BU are the first needle beds.

[0026] The "S + number" in the left column of Figures 2 and 3 indicates the knitting process number. 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 yarn feeder 8 equipped to the flat knitting machine. Thermal fusion yarn 8Y is fed from the yarn feeder 8. The straight arrow indicates the transfer. The newly knitted stitches in each knitting process are shown in thick lines.

[0027] S0 in Fig. 2 shows a state in which the first stitch row 1 is held at BD and the second stitch row 2 is held at FD. The first stitch row 1 constitutes the end in the wale direction of the first knitted fabric portion 5 (Fig. 1). The second stitch row 2 constitutes the end in the wale direction of the second knitted fabric portion 6 (Fig. 1). The first stitch row 1 and the second stitch row 2 are knitted separately by two yarn feeders not shown. Here, the knitted fabric 9 in this example is knitted by full needle knitting. Full needle knitting means that knitting is performed without empty needles between adjacent stitches.

[0028] In S1, a new first stitch row 10 following the first stitch row 1 in the wale direction and a new second stitch row 20 following the second stitch row 2 in the wale direction are knitted using the heat-sealed yarn 8Y fed from the yarn feeder 8 (step X). More specifically, the yarn feeder 8 is moved to the right to knit the new first stitch row 10, and then the yarn feeder 8 is moved to the left to knit the new second stitch row 20. In this example, the first stitch row 1 and the second stitch row 2 are connected in a cylindrical shape. The yarn feeder 8 is a yarn feeder different from the yarn feeder that knits the stitch rows 1 and 2. As the heat-sealed yarn 8Y fed from the yarn feeder 8, for example, a heat-sealed yarn 8Y having a core portion and a sheath portion can be mentioned. The core portion is a knitting yarn made of a material that shrinks by heat. The sheath portion is in the shape of a sheath that covers the outer periphery of the core portion and is made of a material with a melting point lower than the melting point of the core portion. Alternatively, the heat-fusible thread 8Y may be made of a uniform material. The material of the heat-fusible thread 8Y is preferably a material that can ensure stretchability even after being heat-treated.

[0029] The above S1 is a process for improving the strength of the joint, but is not an essential process. Knitting may start from S2 without performing S1.

[0030] In S1, the first stitch row 10 and the second stitch row 20 are each divided into two groups (step A). ​​This grouping is conceptual and is performed within the computer of the flat knitting machine. In this example, in the first stitch row 10, the odd-numbered stitches from the left side of the page are grouped as the first group 11, and the even-numbered stitches from the left side of the page are grouped as the second group 12. Similarly, in the second stitch row 20, the odd-numbered stitches from the left side of the page are grouped as the first group 21, and the even-numbered stitches from the left side of the page are grouped as the second group 22.

[0031] In S2, the stitches of the first group 11 of the first stitch row 10 are moved from BD to FU. In S3, the stitches of the second group 22 of the second stitch row 20 are moved from FD to BU. These steps S2 and S3 are preparation steps for turning the stitches constituting the first joining stitch row 3, which is knitted in the next step S4, into purl stitches. If the stitches constituting the first joining stitch row 3 are to be made into face stitches, it is not necessary to carry out S2 and S3.

[0032] In S4, an arbitrary group X is selected from the first group 11 and the second group 12, and an arbitrary group Y is selected from the first group 21 and the second group 22 (first step B1). When selecting the group X and the group Y, it is preferable that the stitches of the group X and the stitches of the group Y are shifted in the knitting width direction. In this example, the first group 11 is selected as the group X, and the second group 22 is selected as the group Y.

[0033] In S4, the stitches of group X and the stitches of group Y are knitted alternately using the heat-sealing yarn 8Y (first step B2). In this example, the yarn feeder 8 is moved to the right, and the stitches of the first group 11 and the stitches of the second group 22 are knitted alternately. The stitches knitted in S4 are connected in the knitting width direction. The stitches constitute a first joining stitch row 3 that connects the first knitted fabric portion 5 and the second knitted fabric portion 6. Furthermore, a new first joining stitch row 3 may be knitted in the wale direction of the first joining stitch row 3 using the heat-sealing yarn 8Y. In addition, a tubular stitch row may be knitted in the wale direction of the first joining stitch row 3 using the heat-sealing yarn 8Y. By knitting a new first joining stitch row 3 or a tubular stitch row, the strength of the joining portion 7 described later can be improved. In this case, by using thin heat-fusible threads 8Y as the heat-fusible threads 8Y, it is possible to prevent the thickness of the joint 7 from increasing while ensuring the strength of the joint 7.

[0034] In S5, the stitches held at FU are moved to BD among the stitches constituting the first joining stitch row 3. In S6 of Fig. 3, the remaining stitches of the first joining stitch row 3 are moved from BU to FD.

[0035] In S7, the stitches of the first group 21 of the second stitch row 20 (see S1 in FIG. 2) are moved from FD to BU. In S8, the stitches of the second group 12 of the first stitch row 10 (see S1 in FIG. 2) are moved from BD to FU. S7 and S8 are preparatory steps for turning the stitches constituting the second joining stitch row 4, which is knitted in the next S9, into purl stitches, and are not essential steps.

[0036] In S9, group X and group Y are selected from among the groups other than those selected in S4 (second step B1). In this example, the second group 12 of the first knitted fabric portion 5 and the first group 21 of the second knitted fabric portion 6 are selected.

[0037] In S9, the heat-sealing yarn 8Y is further used to knit stitches alternately between the stitches of group X and the stitches of group Y (second process B2). In this example, the yarn feeder 8 is moved leftward to knit stitches alternately between the stitches of the second group 12 and the stitches of the first group 21. The multiple stitches knitted in S9 constitute the second joining stitch row 4 that connects the first knitted fabric portion 5 and the second knitted fabric portion 6. As in S4, the heat-sealing yarn 8Y may be further used to knit a new second joining stitch row 4 or a tubular stitch row.

[0038] In S10, among the stitches constituting the second joining stitch row 4, the stitches held at BU are moved to FD. In S11, the remaining stitches of the second joining stitch row 4 are moved from FU to BD. Through the above steps, the first knitted fabric portion 5 and the second knitted fabric portion 6 are connected by the first joining stitch row 3 and the second joining stitch row 4. The first joining stitch row 3 and the second joining stitch row 4 form a joining portion 7. As shown in S11, the first crossover yarn 30 of the first joining stitch row 3 and the second crossover yarn 40 of the second joining stitch row 4 cross at a position between FD and BD. The crossover yarns 30, 40 are the portions of the joining stitch rows 3, 4 that span between FD and BD.

[0039] After S11, for example, tubular knitting using a withdrawal yarn is performed to remove the knitted fabric 9 from the needle bed while maintaining the stitch shapes of both joining stitch rows 3, 4. The withdrawal yarn is a knitting yarn that will be removed later and is composed of a non-thermal fusion yarn.

[0040] According to the knitting method of the knitted fabric of this example, the number of knitting steps does not increase no matter how long the length in the knitting width direction of the knitting end portion 9E of the knitted fabric 9 shown in Fig. 1 becomes. On the other hand, when the knitting end portion 9E is formed by a bind-off process as in the knitting method of the conventional knitted fabric, the number of knitting steps increases as the length of the knitting end portion 9E becomes longer. Depending on the length of the knitting end portion 9E, the knitting method of the knitted fabric of this example and the knitting method of the conventional knitted fabric may have a difference of more than double in the time from the start to the end of knitting of the knitted fabric 9.

[0041] The state of stitches near the joint 7 in the knitted fabric 9 knitted by the knitting method of the knitted fabric of this example will be described based on the loop diagram of FIG. 4. In FIG. 4, the part knitted by the heat fusion yarn 8Y (see FIGS. 2 and 3) is shown by a thick line. As shown in FIG. 4, the first knitted fabric part 5 arranged on the upper side of the paper and the second knitted fabric part 6 arranged on the lower side of the paper are connected by the joint 7. In this example, the new first knitted fabric row 10 knitted by the heat fusion yarn 8Y and the new second knitted fabric row 20 are regarded as parts of the first knitted fabric part 5 and the second knitted fabric part 6, respectively. The stitch direction of the first knitted fabric part 5 and the stitch direction of the second knitted fabric part 6 are opposite to each other. In the joint 7, there are no double stitches or stitches that are continuous in the wale direction of the double stitches, as in the joint in the bind-off process.

[0042] The joining portion 7 of this example is composed of a first joining stitch row 3 and a second joining stitch row 4. The first joining stitch row 3 and the second joining stitch row 4 are alternately formed in the stitches of the first knitted fabric portion 5 and the stitches of the second knitted fabric portion 6, respectively. Therefore, the first joining stitch row 3 includes a plurality of first crossover yarns 30. The first crossover yarn 30 refers to a portion of the first joining stitch row 3 that spans the first knitted fabric portion 5 and the second knitted fabric portion 6. Similarly, the second joining stitch row 4 includes a plurality of second crossover yarns 40. The second crossover yarn 40 refers to a portion of the second joining stitch row 4 that spans the first knitted fabric portion 5 and the second knitted fabric portion 6. The first crossover yarn 30 and the second crossover yarn 40 cross at the boundary between the joining stitch rows 3 and 4. For convenience of explanation, in FIG. 4, two stitches adjacent to each other in the knitting width direction in the joining stitch rows 3 and 4 are shown separated from each other. Also, the stitches of the first joining stitch row 3 and the stitches of the second joining stitch row 4 that are butted together are shown separated from each other. The stitches and the floating yarns 30, 40 adjacent to the stitches are shown separated from each other. In the actual knitted fabric 9, each stitch of the joining stitch rows 3, 4 shrinks, so that the two stitches are in contact with each other in at least some pairs, and in some cases all pairs, of the pairs of two adjacent stitches. Also, the stitches and the floating yarns 30, 40 are in contact with each other in at least some pairs, and in some cases all pairs, of the pairs of stitches and the floating yarns 30, 40.

[0043] The knitted fabric 9 of this example is set neatly with an iron or the like. A part of the heat-sealing yarn 8Y melts due to the heat of the iron, and the stitches of the joint portion 7 are fused to each other and to the jumping yarns 30, 40. As a result, the heat-sealing yarn 8Y constituting the joint portion 7 becomes difficult to move, and fraying of the stitches constituting the joint portion 7 is suppressed. Here, the removal yarn may be removed before or after the heat treatment. If the removal yarn is water-soluble, it is dissolved and removed from the knitted fabric 9 during washing before the knitted fabric 9 is shipped.

[0044] Representative fusion points in the joining portion 7 are indicated by white arrows. The first stitch row 10, the second stitch row 20, the first joining stitch row 3, and the second joining stitch row 4 are formed of heat fusion yarn 8Y. Therefore, the contact portions between the stitches of the first stitch row 10 and the stitches of the first joining stitch row 3 are fused, and the contact portions between the stitches of the first stitch row 10 and the stitches of the second joining stitch row 4 are fused. Similarly, the contact portions between the stitches of the second stitch row 20 and the stitches of the first joining stitch row 3 are fused, and the contact portions between the stitches of the second stitch row 20 and the stitches of the second joining stitch row 4 are fused.

[0045] At the points where the first and second crossover yarns 30 and 40 cross, the first and second crossover yarns 30 and 40 are in contact with each other. Therefore, the first and second crossover yarns 30 and 40 are fused at the crossover points. The crossover of the first and second crossover yarns 30 and 40 can be easily confirmed when the actual knitted fabric 9 is pulled. In addition, due to the contraction of both crossover yarns 30 and 40, the stitches of the first joining stitch row 3 and the stitches of the second joining stitch row 4, which are in a butted state, are in contact with each other. Therefore, these stitches are also fused. In addition, due to the contraction of the knitted fabric 9, the points where the stitches of the first joining stitch row 3 and the first or second crossover yarn 30 and the stitches of the second joining stitch row 4 and the first or second crossover yarn 40 are in contact with each other are also fused. When the stitches and the jump yarns 30, 40 are fused, the stitches of the stitch rows 10, 20 sandwiched between the stitches and the jump yarns 30, 40 become difficult to move. Furthermore, adjacent stitches in the knitting width direction may also be fused due to contraction of the knitted fabric 9. All of the contacting stitches do not necessarily have to be fused. If the thermal fusion yarn 8Y has high elasticity, the number of contact points between adjacent stitches increases, and the strength of the joint 7 increases.

[0046] In this example, all stitches constituting the joining stitch rows 3 and 4 are purl stitches pulled out from the old stitches from the front side of the paper to the back side. Stitches usually tend to curl in the direction of pulling out from the old stitches. For example, the front stitches of the new first stitch row 10 pulled out from the stitches of the first stitch row 1 to the front side of the paper tend to curl toward the front side of the paper. If all stitches constituting the joining stitch rows 3 and 4 are purl stitches, the stitches of the first joining stitch row 3 and the stitches of the second joining stitch row 4 are fused in a curled state toward the front side of the paper. In this case, the feel and appearance of the joining portion 7 may be impaired. On the other hand, if all stitches constituting the joining stitch rows 3 and 4 are purl stitches as in this example, the purl stitches suppress the first knitted fabric portion 5 and the second knitted fabric portion 6 from curling toward the front side of the paper. As a result, the first knitted fabric portion 5 and the second knitted fabric portion 6 are connected in a planar manner, and the feel and appearance of the joint portion 7 are unlikely to be impaired. Here, it is not necessary that all of the stitches constituting the joint stitch rows 3 and 4 are purl stitches. For example, if 50% or more of all the stitches constituting the first joint stitch row 3 and all the stitches constituting the second joint stitch row 4 are purl stitches, the first knitted fabric portion 5 and the second knitted fabric portion 6 are connected in a planar manner. The higher the ratio of purl stitches, the more preferable. The ratio of purl stitches is, for example, 70% or more, or even 90% or more.

[0047] The joint 7 having the above-mentioned fused state has a predetermined stretchability. This is because the first crossover yarn 30 and the second crossover yarn 40 extending between the first knitted fabric portion 5 and the second knitted fabric portion 6 in the joint 7 allow movement of the knitted fabric 9 in the knitting width direction. If the stretchability of the heat-fused yarn 8Y is high, the stretchability of the joint 9 is further improved.

[0048] <Other embodiments> The flat knitting machine used in the knitting method of the knitted fabric of the present invention may be a two-bed flat knitting machine. In that case, it is preferable that the first stitch row 1 and the second stitch row 2 are in a needle-free state. The needle-free state means a state in which an empty needle is arranged between two adjacent stitches.

[0049] The number of groups in the first stitch row 10 and the second stitch row 20 may be 3 or more. As the number of groups increases, the number of contact points of the heat fusion yarn 8Y at the joint 7 increases, and the strength of the joint 7 increases. On the other hand, if the number of groups increases, the joint 7 may become too thick or the stretchability of the joint 7 may be impaired. Therefore, the number of groups is set to an upper limit of 6.

[0050] The knitting method of the knitted fabric of the present invention can also be used to join the front body and the back body at the shoulder line of the knitwear. The knitting method of the knitted fabric of the present invention can also be used to prevent fraying at the end of the tubular knitted fabric. For example, an example of preventing fraying at the end of the collar will be briefly described. In the middle of knitting the collar, a branch knitted fabric part that branches off from the middle of the collar in the wale direction is knitted. One course of the branch knitted fabric part is sufficient. Next, the collar is knitted to the end. In this case, one of the collar and the branch knitted fabric part is regarded as the first knitted fabric part, and the other is regarded as the second knitted fabric part, and the end of the collar and the branch knitted fabric part are joined by a heat-sealing yarn by the knitting method of the knitted fabric of the present invention. The fraying prevention at the end of the collar is completed by fusing the heat-sealing yarn with an iron or the like. In addition, when a branch knitted fabric part is knitted in the middle of the main knitted fabric part and the main knitted fabric part and the branch knitted fabric part are joined by the knitting method of the knitted fabric of the present invention, for example, a belt loop for pants can be easily formed.
