Description

Technical Field

[0001] The present invention relates to a knitting method of a knitted fabric in which an end portion in the wale direction of a first knitted fabric portion is connected to an end portion in the wale direction of a second knitted fabric portion, and a knitted fabric in which end portions of the first knitted fabric portion and the second knitted fabric portion are joined to each other. Background Art

[0002] Using a flat knitting machine having a first needle bed and a second needle bed, an end portion in the wale direction of a first knitted fabric portion fixed to the first needle bed is joined to an end portion in the wale direction of a second knitted fabric portion fixed to the second needle bed. For example, Patent Document 1 discloses a knitting method of a knitted fabric in which a first knitted fabric portion and a second knitted fabric portion are joined by a hemming process (Japanese: fushime shori). The hemming process is a process of repeatedly performing the following: forming an overlapping coil in which two adjacent coils are overlapped, and knitting a new coil in the overlapping coil. In the joined portion formed by the hemming process, the unraveling of the coil is suppressed.

[0006] The appearance and stretchability of the joined portion formed by the hemming process are excellent. However, it is necessary to process the coils one by one, and the number of processes for forming the joined portion is very large. In particular, when the length of the joining becomes longer, the time for forming the joined portion becomes very long. Summary of the Invention

[0007] Problems to be Solved by the Invention

[0008] One object of the present invention is to provide a knitting method of a knitted fabric that can simply connect a first knitted fabric portion and a second knitted fabric portion as compared with the hemming process. One object of the present invention is to provide a knitted fabric having a joined portion and manufactured with good productivity.

[0009] Means for Solving the Problems

[0010] <1>The knitting method of the knitted fabric of the present invention uses a flat knitting machine having a first needle bed and a second needle bed, and connects a first coil row of a first knitted fabric portion fixed to the first needle bed and a second coil row of a second knitted fabric portion fixed to the second needle bed.

[0011] The knitting method of the knitted fabric includes:

[0012] Step A, in which a plurality of coils constituting the first coil row are divided into n groups, and a plurality of coils constituting the second coil row are divided into m groups; and

[0013] Process B, in which Process B1 and Process B2 are repeatedly performed until there are no selectable groups.

[0014] In Process B1, one group X is selected from the n groups, and one group Y is selected from the m groups.

[0015] In Process B2, the coils continuous in the wale direction of each coil in group X and the coils continuous in the wale direction of each coil in group Y are knitted using heat-sealing yarns.

[0016] The number of groups m and n in Process A is the same, and is 2 or more and 6 or less.

[0017] In the above knitting method of the knitted fabric, the number of groups is the same as the number of repetitions of Process B1 and Process B2. For example, when the first coil row and the second coil row are each divided into 3 groups, in the first Process B1, one group from the 3 groups of the first coil row and one group from the 3 groups of the second coil row are selected, and the first Process B2 is performed. In the second Process B1, groups X and Y are selected from the groups not selected in the first Process B1, and the second Process B2 is performed. Then, in the third Process B1, the remaining one group of the first coil row and the remaining one group of the second coil row are selected, and the third Process B2 is performed.

[0018] The number of coils in each group constituting the first coil row and the number of coils in each group constituting the second coil row may be the same or different. For example, when the first coil row composed of 12 coils is divided into 2 groups, it may be that the number of coils in the first group is 6 and the number of coils in the second group is also 6, or it may be that the number of coils in the first group is 4 and the number of coils in the second group is 8. The number of coils in group X and the number of coils in group Y may be the same or different.

[0019] Preferably, in Process A, the coils are grouped in such a way that the arrangement ranges of the coils in each group overlap with those of the coils in other groups in the knitting width direction. As a result, in each group in the first coil row and the second coil row, there is a portion sandwiched by the coils of other groups between two coils arranged along the knitting width direction of each group. For example, when the first coil row is divided into a first group and a second group, as shown in Example 1 below, a pattern in which the coils of the first group and the second group are alternately arranged in the knitting width direction can be cited. As shown in Example 2 below, the first group may also include a portion where the coils constituting the first group are adjacent to each other, and the second group may also include a portion where the coils constituting the second group are adjacent to each other. As shown in Example 3 below, the coils of the first group and the second group may also be irregularly arranged. In addition, in Examples 1 to 3 below, "○" represents the coils of the first group, and "×" represents the coils of the second group.

[0020] · Example 1... ○×○×○×○×○×○×

[0021] · Example 2... ○○××○○××○○××

[0022] · Example 3... ○×○○××○○×○××

[0023] <2> As one aspect of the knitting method of the knitted fabric of the present invention, the following aspect can be cited:

[0024] All the coils knitted in the process B2 are reverse coils.

[0025] A reverse coil refers to a coil knitted in a needle bed facing the needle bed where the knitted fabric portion is fixed. For example, when continuously knitting a reverse coil with respect to coil A of the first knitted fabric portion fixed to the first needle bed, after moving coil A to the second needle bed, a coil B continuous with coil A is knitted. This coil B becomes a reverse coil.

[0026] <3> As one aspect of the knitting method of the knitted fabric of the present invention, the following aspect can be cited:

[0027] Each of the n groups is composed of coils separated by n - 1 coils,

[0028] Each of the m groups is composed of coils separated by m - 1 coils.

[0029] As a specific example of the above-described form <3>, a case where the coils of the first coil row composed of 12 coils are divided into 3 groups will be described. In this case, the first group is composed of the 1st, 4th, 7th, and 10th coils counted from one end in the knitting width direction of the first coil row. The second group is composed of the 2nd, 5th, 8th, and 11th coils. The third group is composed of the 3rd, 6th, 9th, and 12th coils. In this case, in the process B2, the coils continuous in the coil longitudinal direction of each coil in group X and the coils continuous in the coil longitudinal direction of each coil in group Y are knitted alternately.

[0030] <4>As one form of the knitting method of the knitted fabric of the present invention, the following form can be cited:

[0031] Before the process A, a process X is provided, and in the process X, at least one of a new first coil row continuous in the coil longitudinal direction of the first coil row and a new second coil row continuous in the coil longitudinal direction of the second coil row is knitted using the heat-sealing yarn.

[0032] <5>The knitted fabric of the present invention has a joint portion that joins the terminal portions of the first knitted fabric portion and the second knitted fabric portion to each other.

[0033] The joint portion is composed of a plurality of joint coil rows different from the first knitted fabric portion and the second knitted fabric portion.

[0034] Each joint coil row is composed of coils formed in a part of the terminal portion of the first knitted fabric portion and a part of the terminal portion of the second knitted fabric portion.

[0035] The knitting yarn constituting each joint coil row is a heat-sealing yarn.

[0036] The connecting yarns in each joint coil row and the connecting yarns in other joint coil rows are welded in a crossed state.

[0037] At least a part of the coils in each joint coil row and the coils in other joint coil rows are welded in a contact state.

[0038] The connecting yarn spans the first knitted fabric portion and the second knitted fabric portion.

[0039] Advantages of the Invention

[0040] According to the knitting method of the knitted fabric of the present invention, the first knitted fabric portion and the second knitted fabric portion can be connected with a significantly smaller number of processes than the bead pressing process. Specifically, the first knitted fabric portion and the second knitted fabric portion can be connected only by repeating the process B1 and the process B2 the same number of times as the number of groups.

[0041] By implementing the knitting method of the knitted fabric of the present invention, the terminal portions of the first knitted fabric portion and the second knitted fabric portion are connected to each other by a plurality of joining coil rows formed of heat-sealing yarns. By heat treatment such as ironing, a part of the heat-sealing yarns is melted, and thus the portions where the heat-sealing yarns are in contact are welded. The portions where the heat-sealing yarns are in contact are the portions where the heat-sealing yarns are in contact with each other and the portions where the heat-sealing yarns are in contact with non-heat-sealing yarns. As the portions where the heat-sealing yarns are in contact with each other, the portions where the connecting yarns cross each other, the portions where adjacent coils overlap each other, etc. can be cited. Through this welding, 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 can be obtained.

[0042] According to the knitting method of the knitted fabric described in <2> above, the first knitted fabric portion and the second knitted fabric portion can be connected flatly. This will be described in detail in the embodiments.

[0043] According to the knitting method of the knitted fabric described in <3> above, the coils formed of the heat-sealing yarns connecting the first knitted fabric portion and the second knitted fabric portion are regularly arranged. As a result, the joining portion of the first knitted fabric portion and the second knitted fabric portion is beautifully completed.

[0044] According to the knitting method of the knitted fabric described in <4> above, the contact points where the heat-sealing yarns are in contact with each other increase. As a result, the strength of the joining portion is improved.

[0045] The knitted fabric of the present invention has a joining portion and excellent productivity. This is because the plurality of joining coil rows constituting the joining portion are knitted in an extremely short time by the knitting method of the knitted fabric of the present invention.

[0071] Hereinafter, based on the accompanying drawings, the knitting method and the fabric of the implementation mode will be described.

[0072] <Embodiment 1>

[0073] Figure 1 The shown fabric 9 is a long skirt knitted horizontally on a flat knitting machine. The fabric 9 has a start part of knitting 9S formed at the left side end of the paper surface and an end part of knitting 9E formed at the right side end of the paper surface. When knitting this skirt, first, the start part of knitting 9S that forms the side end of the skirt is knitted. Next, the first fabric part 5 and the second fabric part 6 branched from the start part of knitting 9S are knitted. Finally, the end part of knitting 9E is formed by connecting the first fabric part 5 and the second fabric part 6. The knitting method of the fabric of the present invention is applied in the formation of this end part of knitting 9E.

[0074] Figure 2 、 3It is a knitting process diagram showing the specific knitting process 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 includes a lower front bed, a lower rear bed, an upper front bed, and an upper rear bed. Hereinafter, the lower front bed, the lower rear bed, the upper front bed, and the upper rear bed are denoted as FD, BD, FU, and BU, respectively. FD and BD face each other. FU disposed above FD and BU disposed above BD face each other. In this example, FD and FU are the second beds, and BD and BU are the first beds.

[0075] Figure 2 , 3 The "S + number" in the left column of indicates the number of the knitting process. The knitting state of the loops in each knitting process is shown in the right column. The black dots in the right column represent knitting needles, and the inverted triangle marks represent the yarn feeders 8 provided in the flat knitting machine. The heat-sealable yarn 8Y is supplied from the yarn feeder 8. The straight arrows represent loop transfer. The newly knitted loops in each knitting process are represented by thick lines.

[0076] In Figure 2 S0 of, the state where the first coil row 1 is fixed to BD and the second coil row 2 is fixed to FD is shown. The first coil row 1 constitutes the end portion in the wale direction of the first knitted fabric portion 5 ( Figure 1 ). The second coil row 2 constitutes the end portion in the wale direction of the second knitted fabric portion 6 ( Figure 1 ). The first coil row 1 and the second coil 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 knitting in a state where there are no empty needles between adjacent loops.

[0077] In S1, using the heat-sealable yarn 8Y supplied from the yarn feeder 8, a new first coil row 10 continuous in the wale direction of the first coil row 1 and a new second coil row 20 continuous in the wale direction of the second coil row 2 are knitted (process X). More specifically, the yarn feeder 8 is moved to the right to knit the new first coil row 10, and then the yarn feeder 8 is moved to the left to knit the new second coil row 20. In this example, the new first coil row 10 and the new second coil row 20 are connected in a tubular shape. The yarn feeder 8 is a different yarn feeder from the yarn feeders for knitting the coil rows 1 and 2. As the heat-sealable yarn 8Y supplied from the yarn feeder 8, for example, a heat-sealable yarn 8Y having a core portion and a sheath portion can be cited. The core portion is a knitting yarn made of a material that shrinks due to heat. The sheath portion is made of a sheath-shaped material that covers the outer periphery of the core portion and has a lower melting point than the melting point of the core portion. In addition, the heat-sealable yarn 8Y can also be made of the same material. The material of the heat-sealable yarn 8Y is preferably a material that can ensure stretchability even after being heat-treated.

[0078] The above S1 is a process for enhancing the strength of the joint, but it is not an essential process. It is also possible to start knitting from S2 without performing S1.

[0079] In S1, the first coil row 10 and the second coil row 20 are each divided into two groups (process A). This grouping is conceptual and is carried out within the computer of the flat knitting machine. In this example, the odd-numbered coils starting from the left side of the paper surface in the first coil row 10 are taken as the first group 11, and the even-numbered coils are taken as the second group 12. Similarly, the odd-numbered coils starting from the left side of the paper surface in the second coil row 20 are taken as the first group 21, and the even-numbered coils are taken as the second group 22.

[0080] In S2, the coils of the first group 11 of the first coil row 10 are moved from BD to FU. In S3, the coils of the second group 22 of the second coil row 20 are moved from FD to BU. These S2 and S3 are preparatory processes for making the coils that form the first joint coil row 3 knitted in the subsequent S4 into reverse coils. In the case of making the coils that form the first joint coil row 3 into front coils, S2 and S3 do not need to be implemented.

[0081] In S4, any group X is selected from the first group 11 and the second group 12, and any group Y is selected from the first group 21 and the second group 22 (the first process B1). When selecting group X and group Y, it is preferable that the coils of group X and the coils of group Y are offset in the knitting width direction. In this example, the first group 11 is selected as group X, and the second group 22 is selected as group Y.

[0082] In S4, further using the hot melt yarn 8Y, coils are knitted alternately in the coils of group X and the coils of group Y (the first process B2). In this example, the yarn feeder 8 is moved in the right direction, and coils are knitted alternately in the coils of the first group 11 and the coils of the second group 22. The multiple coils knitted in this S4 are connected in the knitting width direction. These multiple coils form the first joint coil row 3 that connects the first knitted fabric part 5 and the second knitted fabric part 6. Moreover, it is also possible to use the hot melt yarn 8Y to continuously knit a new first joint coil row 3 in the wale direction of the coils of the first joint coil row 3. In addition, it is also possible to use the hot melt yarn 8Y to continuously knit a tubular coil row in the wale direction of the coils of the first joint coil row 3. By knitting a new first joint coil row 3 and a tubular coil row, the strength of the joint part 7 described later can be enhanced. In this case, if a thin hot melt yarn 8Y is used as the hot melt yarn 8Y, it is possible to suppress the thickening of the joint part 7 while ensuring the strength of the joint part 7.

[0083] In S5, the coils of the first joint coil row 3 that are fixed to FU are moved to BD. Figure 3In S6, the remaining coils of the first joining coil row 3 are moved from BU to FD.

[0084] In S7, the coils of the first group 21 of the second coil row 20 (refer to Figure 2 S1) are moved from FD to BU. In S8, the coils of the second group 12 of the first coil row 10 (refer to Figure 2 S1) are moved from BD to FU. S7 and S8 are preparatory processes for making the coils constituting the second joining coil row 4 to be knitted in the next S9 into reverse coils, and are not essential structures.

[0085] In S9, groups X and Y are selected from groups other than the group selected in S4 (second process B1). In this example, the second group 12 of the first knitted fabric part 5 and the first group 21 of the second knitted fabric part 6 are selected.

[0086] In S9, further using the heat-sealing yarn 8Y, coils are alternately knitted in the coils of group X and the coils of group Y (second process B2). In this example, the yarn feeder 8 is moved in the left direction, and coils are alternately knitted in the coils of the second group 12 and the coils of the first group 21. The multiple coils knitted in this S9 constitute the second joining coil row 4 that connects the first knitted fabric part 5 and the second knitted fabric part 6. Similarly to S4, new second joining coil rows 4 and tubular coil rows can also be knitted further using the heat-sealing yarn 8Y.

[0087] In S10, the coils of the second joining coil row 4 that are fixed to BU are moved to FD. In S11, the remaining coils of the second joining coil row 4 are moved from FU to BD. Through the above processes, the first knitted fabric part 5 and the second knitted fabric part 6 are in a state connected by the first joining coil row 3 and the second joining coil row 4. The joining part 7 is formed by the first joining coil row 3 and the second joining coil row 4. As shown in S11, the first connecting yarn 30 of the first joining coil row 3 and the second connecting yarn 40 of the second joining coil row 4 cross at a position between FD and BD. The connecting yarns 30, 40 are the parts in the joining coil rows 3, 4 that span FD and BD.

[0088] After S11, for example, by performing bag knitting using a separating course yarn, etc., the knitted fabric 9 is removed from the needle bed while maintaining the shape of the coils of the two joining coil rows 3, 4. The separating course yarn is a knitted yarn that is removed later and is composed of a non-heat-sealing yarn.

[0089] According to the knitting method of the knitted fabric of this example, regardless of Figure 1No matter how long the length of the knitting width direction of the knitting end portion 9E of the shown knitted fabric 9 becomes, the number of knitting processes will not increase. On the other hand, in the case of forming the knitting end portion 9E by the pressing loop process as in the conventional knitting method of knitted fabrics, the longer the length of the knitting end portion 9E is, the more the number of knitting processes increases. Depending on the length of the knitting end portion 9E, there can be a difference of several times or more in the time from the start to the end of knitting of the knitted fabric 9 between the knitting method of the knitted fabric in this example and the conventional knitting method of knitted fabrics.

[0090] Based on Figure 4 the coil diagram, the state of the coils near the joint portion 7 in the knitted fabric 9 knitted by the knitting method of the knitted fabric in this example will be described. In Figure 4 it, the portions knitted by the heat-sealable yarn 8Y (refer to Figure 2 , 3 ) are shown in thick lines. As Figure 4 shown, the first knitted fabric portion 5 arranged on the upper side of the paper surface and the second knitted fabric portion 6 arranged on the lower side of the paper surface are connected by the joint portion 7. In this example, the new first coil row 10 and the new second coil row 20 knitted by the heat-sealable yarn 8Y are regarded as part of the first knitted fabric portion 5 and the second knitted fabric portion 6, respectively. The orientation of the coils of the first knitted fabric portion 5 and the orientation of the coils of the second knitted fabric portion 6 are opposite to each other. At the joint portion 7, there are no overlapping coils such as those in the joint portion in the pressing loop process and no coils continuous in the wale direction of the overlapping coils.

[0091] The joint portion 7 in this example is composed of a first joint coil row 3 and a second joint coil row 4. The first joint coil row 3 and the second joint coil row 4 are alternately formed in the coils of the first knitted fabric portion 5 and the coils of the second knitted fabric portion 6. Therefore, the first joint coil row 3 includes a plurality of first connecting yarns 30. The first connecting yarn 30 refers to the portion in the first joint coil row 3 that spans the first knitted fabric portion 5 and the second knitted fabric portion 6. Similarly, the second joint coil row 4 includes a plurality of second connecting yarns 40. The second connecting yarn 40 refers to the portion in the second joint coil row 4 that spans the first knitted fabric portion 5 and the second knitted fabric portion 6. The first connecting yarn 30 and the second connecting yarn 40 cross at the position of the boundary between the two joint coil rows 3 and 4. In Figure 4In order to facilitate the description, two adjacent coils in the knitting width direction in the joining coil rows 3 and 4 are shown in a mutually separated state. In addition, the coils of the first joining coil row 3 and the second joining coil row 4 that are butt-jointed are shown in a mutually separated state. The coil and the connecting yarns 30 and 40 adjacent to the coil are shown in a mutually separated state. In the actual knitted fabric 9, since the coils of the joining coil rows 3 and 4 contract, the two coils are in contact with each other in at least a part of the groups composed of two adjacent coils, and all the groups in some cases. In addition, the coil is in contact with the connecting yarns 30 and 40 in at least a part of the groups composed of the coil and the connecting yarns 30 and 40, and all the groups in some cases.

[0092] The knitted fabric 9 of this example is beautifully arranged by an iron or the like. Due to the heat of the iron, a part of the heat-fusible yarn 8Y melts, and the coils of the joint part 7 and the coils and the connecting yarns 30 and 40 are fused. As a result, the heat-fusible yarn 8Y constituting the joint part 7 is difficult to move, and the unraveling of the coils constituting the joint part 7 is suppressed. Here, the separating crosswise yarn can be removed before the heat treatment or after the heat treatment. If the separating crosswise yarn is water-soluble, the separating crosswise yarn dissolves and is removed from the knitted fabric 9 during washing before the knitted fabric 9 is shipped.

[0093] The representative fusion points in the joint part 7 are indicated by hollow arrows. The first coil row 10, the second coil row 20, the first joining coil row 3, and the second joining coil row 4 are constituted by the heat-fusible yarn 8Y. Therefore, the contact part between the coils of the first coil row 10 and the coils of the first joining coil row 3 is fused, and the contact part between the coils of the first coil row 10 and the coils of the second joining coil row 4 is fused. Similarly, the contact part between the coils of the second coil row 20 and the coils of the first joining coil row 3 is fused, and the contact part between the coils of the second coil row 20 and the coils of the second joining coil row 4 is fused.

[0094] At the portion where the first connecting yarn 30 and the second connecting yarn 40 cross, the first connecting yarn 30 contacts the second connecting yarn 40. Therefore, at the crossing portion, the first connecting yarn 30 and the second connecting yarn 40 are fused. The crossing of the first connecting yarn 30 and the second connecting yarn 40 can be easily confirmed when stretching the actual knitted fabric 9. In addition, due to the shrinkage of the two connecting yarns 30 and 40, the loops of the first joining loop row 3 and the loops of the second joining loop row 4 that are in a butted state come into contact. Therefore, these loops are also fused. In addition, due to the shrinkage of the knitted fabric 9, the portions where the loops of the first joining loop row 3 contact the first connecting yarn 30 or the second connecting yarn 40, and the portions where the loops of the second joining loop row 4 contact the first connecting yarn 30 or the second connecting yarn 40 are also fused. When the loops are fused with the connecting yarns 30 and 40, the loops of the loop rows 10 and 20 sandwiched by the loops and the connecting yarns 30 and 40 are difficult to move. Moreover, due to the shrinkage of the knitted fabric 9, the loops adjacent to each other in the knitting width direction may sometimes be fused. It is not necessary for all of the contacting loops to be fused. If the stretchability of the hot melt joining yarn 8Y is high, the contact portions between adjacent loops increase, and the strength of the joint portion 7 increases.

[0095] In this example, all of the loops constituting the joining loop rows 3 and 4 are reverse loops drawn out from the old loops from the front side near the paper surface toward the inside. Loops generally tend to curl in the direction of being drawn out from the old loops. For example, the front loops of the new first loop row 10 drawn out from the loops of the first loop row 1 toward the front side near the paper surface tend to curl toward the front side near the paper surface. If all of the loops constituting the joining loop rows 3 and 4 were front loops, the loops of the first joining loop row 3 and the loops of the second joining loop row 4 would be fused in a state of curling toward the front side near the paper surface. In this case, the touch and appearance of the joint portion 7 may be impaired. On the other hand, if all of the loops constituting the joining loop rows 3 and 4 are reverse loops as in this example, these reverse loops suppress the curling of the first knitted fabric portion 5 and the second knitted fabric portion 6 toward the front side near the paper surface. As a result, the first knitted fabric portion 5 and the second knitted fabric portion 6 are connected flatly, and the touch and appearance of the joint portion 7 are not easily damaged. Here, not all of the loops constituting the joining loop rows 3 and 4 have to be reverse loops. For example, if more than 50% of the loops of all of the loops constituting the first joining loop row 3 and all of the loops constituting the second joining loop row 4 are reverse loops, the first knitted fabric portion 5 and the second knitted fabric portion 6 are connected flatly. The higher the ratio of the reverse loops, the more preferable. The ratio of the reverse loops is, for example, 70% or more, and further 90% or more.

[0096] The joint portion 7 having the above-described welding state has a predetermined stretchability. This is because, in the joint portion 7, the first connecting yarn 30 and the second connecting yarn 40 spanning between the first knitted fabric portion 5 and the second knitted fabric portion 6 allow movement in the knitting width direction of the joint portion 7. If the stretchability of the hot-melt welding yarn 8Y is high, the stretchability of the joint portion 7 is further improved.

[0097] <Other embodiments>

[0098] The flat knitting machine used in the knitting method of the knitted fabric of the present invention may also be a double-bed flat knitting machine. In this case, it is preferable to set the first coil row 1 and the second coil row 2 in the off-needle state. The off-needle state means a state in which an empty needle is arranged between two adjacent coils.

[0099] The number of groups of the first coil row 10 and the second coil row 20 may also be 3 or more. The more the number of groups, the more the contact points of the hot-melt welding yarn 8Y in the joint portion 7 increase, and thus the strength of the joint portion 7 increases. On the other hand, if the number of groups increases, the joint portion 7 becomes too thick, or the stretchability of the joint portion 7 may be impaired. Therefore, the upper limit of the number of groups is 6.

[0100] The knitting method of the knitted fabric of the present invention can also be used to join the front body piece and the back body piece at the shoulder line of the knitted product. In addition, the knitting method of the knitted fabric of the present invention can also be used to prevent the unsealing of the end portion of the tubular knitted fabric. For example, an example of preventing the unsealing of the end portion of the collar will be briefly described. In the middle of knitting the collar, a branched knitted fabric portion branched from the middle of the collar in the longitudinal direction of the coils is knitted. The branched knitted fabric portion may be an amount of 1 coil row. Then, the collar is knitted until the end. In this case, one of the collar and the branched knitted fabric portion is regarded as the first knitted fabric portion, and the other is regarded as the second knitted fabric portion. By the knitting method of the knitted fabric of the present invention, the end portion of the collar is joined to the branched knitted fabric portion by using the hot-melt welding yarn. By melting the hot-melt welding yarn using an iron or the like, the prevention of the unsealing of the end portion of the collar is completed. In addition, when the branched knitted fabric portion is knitted in the middle of the main knitted fabric portion and the main knitted fabric portion and the branched knitted fabric portion are joined by the knitting method of the knitted fabric of the present invention, for example, it is also possible to easily form a belt hole of the pants.
