Description

The present invention provides a knitting method of a knitted fabric that connects a wale-direction end of a first knitted fabric portion and a wale-direction end of a second knitted fabric portion, and a terminal end of the first knitted fabric portion and the second knitted fabric portion. It relates to a knitted fabric in which parts are joined together.

Using a flat knitting machine having a first needle bed and a second needle bed, a wale direction end portion of a first knitted fabric portion held by the first needle bed and held by the second needle bed The wale direction ends of the second knitted fabric portion are joined together. For example, Patent Document 1 discloses a method of knitting a knitted fabric in which a first knitted fabric portion and a second knitted fabric portion are joined by a bind-off process. The bind-off process is a process of repeatedly forming a double stitch by overlapping two adjacent stitches and knitting a new stitch on the double stitch. Fraying of the stitches is suppressed in the joined portion joined by the bind off process.

WO2011/018929

The joints formed by the bind-off process are excellent in appearance and stretchability. However, stitches must be processed one by one, and the number of processes for forming the joint is very large. In particular, when the length to be joined is long, the time required to form the joint becomes very long.

One of the objects of the present invention is to provide a knitting method of a knitted fabric that can connect the first knitted fabric portion and the second knitted fabric portion more easily than bind-off processing. One of the objects of the present invention is to provide a knitted fabric that has joints and is manufactured with good productivity.

<1> The knitting method of the knitted fabric of the present invention comprises:
Using a flat knitting machine having a first needle bed and a second needle bed,
A method of knitting 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. in
a step A of dividing the plurality of stitches forming the first stitch row into n groups, and dividing the plurality of stitches forming the second stitch row into m groups;
including a step B of repeating steps B1 and B2 until there are no groups that can be selected;
In step B1, selecting one group X from the n groups and selecting one group Y from the m groups;
In the step B2, a heat-fusible yarn is used to knit a stitch continuing in the wale direction of each stitch of the group X and a stitch continuing in the wale direction of each stitch of the group Y,
The numbers of groups m and n in the step A are the same number and are 2 or more and 6 or less.

In the knitting method of the knitted fabric, the number of groups matches the number of repetitions of the steps B1 and B2. For example, when the first stitch row and the second stitch row are each divided into three groups, in the first step B1, one of the three groups of the first stitch row and the three groups of the second stitch row One of the groups is selected and step B2 is performed for the first time. In the second step B1, the groups X and 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 one group of the first stitch row and the remaining one group of the second stitch row are selected, and the third step B2 is performed.

The number of stitches in each group forming the first stitch row and the number of stitches forming the second stitch row may be the same or different. For example, when dividing the first stitch row consisting of 12 stitches into two groups, the number of stitches in the first group may be 6 and the number of stitches in the second group may also be 6. The number of stitches in the second group may be four, and the number of stitches in the second group may be eight. The number of stitches in group X and the number of stitches in group Y may be the same or different.

In step A, the grouping is preferably performed so that the stitch arrangement range of each group overlaps the stitch arrangement range of another group in the knitting width direction. As a result, each group in the first stitch row and the second stitch row has a portion where a stitch of another group is sandwiched between two stitches of each group arranged in the knitting width direction. For example, when the first stitch row is divided into a first group and a second group, as shown in Example 1 below, the stitches of the first group and the stitches of the second group are alternately arranged in the knitting width direction. are mentioned. As shown in Example 2 below, the first group may include a portion where the stitches forming the first group are adjacent to each other, and the second group may include a portion where the stitches forming the second group are adjacent to each other. May contain parts. 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 "X" indicates the stitches of the second group.

<2> As one embodiment of the knitting method of the knitted fabric of the present invention,
For example, the stitches knitted in the step B2 are all back stitches.

The purl stitch is a stitch knitted on a needle bed facing the needle bed on which the knitted fabric portion is held. For example, when knitting the back stitch following the stitch A of the first knitted fabric portion held on the first needle bed, after moving the stitch A to the second needle bed, the stitch B continuing to the stitch A is knitted. do. This stitch B is a back stitch.

<3> As one embodiment of the knitting method of the knitted fabric of the present invention,
Each of the n groups consists of every n-1 stitches,
Each of the m groups may be formed of every m-1 stitches.

As a specific example of the above mode <3>, a case will be described in which the stitches of the first stitch row made up of 12 stitches are divided into three groups. In this case, the first group is composed of the 1st, 4th, 7th, and 10th stitches counted from one end of the first stitch row in the knitting width direction. The second group is composed of the 2nd, 5th, 8th and 11th stitches. The third group is composed of the 3rd, 6th, 9th and 12th stitches. In this case, in the step B2, the stitches of the stitches of the group X continuing in the wale direction and the stitches of the stitches of the group Y continuing in the wale direction are alternately knitted.

<4> As one embodiment of the knitting method of the knitted fabric of the present invention,
Before the step A, using the heat-fusible yarn, a new first stitch row following the wale direction of the first stitch row and a new second stitch row following the wale direction of the second stitch row A form comprising a step X of knitting at least one of.

<5> The knitted fabric of the present invention is
In the knitted fabric having a joint portion that joins the end portions of the first knitted fabric portion and the second knitted fabric portion,
The joint portion is composed of a plurality of joint stitch rows different from the first knitted fabric portion and the second knitted fabric portion,
Each joining stitch row consists of stitches formed at a part of the terminal part of the first knitted fabric part and a part of the terminal part of the second knitted fabric part,
The knitting yarn constituting each joining stitch row is a heat-fusible yarn,
The jump yarn in each joint stitch row and the jump yarn in the other joint stitch row are fused in a crossed state,
At least part of the stitches in each joined stitch row and the stitches in the other joined stitch rows are fused in a contact state,
The jump yarn straddles the first knitted fabric portion and the second knitted fabric portion.

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 joined with a dramatically smaller number of steps than the bind off process. Specifically, the first knitted fabric portion and the second knitted fabric portion can be connected simply by repeating the steps B1 and B2 as many times as the number of groups.

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 by a plurality of joining stitch rows constituted by heat-sealing yarns. A portion of the heat-fusible yarn is melted by heat treatment such as ironing, so that the contacting portions of the heat-fusible yarn are fused. The points where the heat-fusible yarns contact are the points where the heat-fusible yarns contact each other and the points where the heat-fusible yarns and the non-heat-fusible yarns contact each other. Locations where the heat-fusible yarns come into contact include locations where jumping yarns intersect and locations where adjacent stitches overlap each other. By this fusion, the knitted fabric of the present invention is obtained which has a joining portion that firmly joins the first knitted fabric portion and the second knitted fabric portion.

According to the method of knitting a knitted fabric according to <2> above, the first knitted fabric portion and the second knitted fabric portion can be connected two-dimensionally. This point will be described in detail in the embodiment.

According to the method of knitting a knitted fabric according to <3> above, the stitches made of the heat-fusible yarn connecting the first knitted fabric portion and the second knitted fabric portion are regularly arranged. As a result, the joint portion between the first knitted fabric portion and the second knitted fabric portion is beautifully finished.

According to the method of knitting a knitted fabric according to <4> above, the number of contact points where the heat-fusible yarns come into contact with each other is increased. As a result, the strength of the joint is improved.

The knitted fabric of the present invention is excellent in productivity even though it has a joint portion. This is because the plurality of joined stitch rows forming the joined portion are knitted in a very short time by the knitting method of the knitted fabric of the present invention.

FIG. 1 is a schematic configuration diagram of a skirt, which is a knitted fabric according to an embodiment. FIG. 2 is a first knitting process diagram of the knitting method of the knitted fabric according to the embodiment. FIG. 3 is a second knitting process diagram following FIG. FIG. 4 is a loop diagram showing the state of stitches in the vicinity of the joint portion of the knitted fabric according to the embodiment.

A method of knitting a knitted fabric and a knitted fabric according to an embodiment will be described below with reference to the drawings.

<Embodiment 1>
A knitted fabric 9 shown in FIG. 1 is a long skirt knitted sideways on a flat knitting machine. The knitted fabric 9 includes a set-up portion 9S formed at the left side edge on the page and a knitting end portion 9E formed at the right side edge on the page. To knit this skirt, first, the set-up portion 9S that becomes the side end of the skirt is knitted. Next, the first knitted fabric portion 5 and the second knitted fabric portion 6 branched 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 a 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.

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. A four-bed flat knitting machine includes a lower front needle bed, a lower back needle bed, an upper front needle bed, and an upper back needle bed. The lower front needle bed, the lower back needle bed, the upper front needle bed, and the upper back needle bed are hereinafter referred to as FD, BD, FU, and BU, respectively. 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, FD and FU are the second needle beds, and BD and BU are the first needle beds.

"S+Number" in the left column of FIGS. 2 and 3 indicates the number of the knitting process. The right column shows the knitting state of the stitches in each knitting process. A black dot in the right column indicates a knitting needle, and an inverted triangle mark indicates a yarn feeder 8 provided in the flat knitting machine. A yarn feeder 8 feeds a heat-fusible yarn 8Y. A straight arrow indicates the transfer. The stitches newly knitted in each knitting process are indicated by thick lines.

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

In S1, using the heat-fusible yarn 8Y supplied from the yarn feeder 8, a new first stitch row 10 continuing in the wale direction of the first stitch row 1 and a new new stitch row 10 continuing in the wale direction of the second stitch row 2 A second stitch row 20 is knitted (step X). More specifically, after the yarn feeder 8 is moved rightward to knit a new first stitch row 10, the yarn feeder 8 is moved leftward to knit a new second stitch row 20. In this example, the first stitch row 1 and the second stitch row 2 are connected in a tubular 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-fusible yarn 8Y fed from the yarn feeder 8, for example, a heat-fusible yarn 8Y having a core portion and a sheath portion can be used. The core is a knitting yarn made of a material that shrinks when heated. The sheath is sheath-shaped and covers the outer periphery of the core, and is made of a material having a melting point lower than that of the core. 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.

Although the above S1 is a step for improving the strength of the joint, it is not an essential step. Knitting may be started from S2 without performing S1.

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 done in 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 drawing are the first group 11 , and the even-numbered stitches are the second group 12 . Similarly, in the second row of stitches 20 , the odd-numbered stitches from the left side of the drawing are a first group 21 , and the even-numbered stitches are a second group 22 .

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 S2 and S3 are preparatory steps for backing the stitches forming the first joining stitch row 3 knitted in the next S4. When the stitches forming the first joining stitch row 3 are the front stitches, there is no need to perform S2 and S3.

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. FIG.

Further, in S4, the stitches of the group X and the stitches of the group Y are alternately knitted using the heat-fusible yarn 8Y (first step B2). In this example, the yarn feeder 8 is moved rightward, and the stitches of the first group 11 and the stitches of the second group 22 are alternately knitted. The plurality of stitches knitted in S4 are connected in the knitting width direction. The plurality of stitches constitute the 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 following the wale direction of the first joining stitch row 3 using the heat-fusible yarn 8Y. In addition, a tubular stitch row may be knitted continuously in the wale direction of the first joining stitch row 3 using the heat-fusible yarn 8Y. By knitting a new first joining stitch row 3 or a new tubular stitch row, the strength of the joint portion 7, which will be described later, can be improved. In this case, if a thin heat-fusible yarn 8Y is used as the heat-fusible yarn 8Y, it is possible to prevent the thickness of the joint 7 while ensuring the strength of the joint 7 .

In S5, among the stitches forming the first joining stitch row 3, the stitches held by the FU are moved to the BD. In S6 of FIG. 3, the remaining stitches of the first joining stitch row 3 are moved from BU to FD.

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. These S7 and S8 are preparatory steps for backing the stitches forming the second joining stitch row 4 knitted in the next S9, and are not essential configurations.

In S9, group X and group Y are selected from groups other than the group 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.

Further, in S9, the stitches of the group X and the stitches of the group Y are alternately knitted using the heat-fusible yarn 8Y (second step B2). In this example, the yarn feeder 8 is moved leftward, and the stitches of the second group 12 and the stitches of the first group 21 are alternately knitted. The plurality of 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, a new second joining stitch row 4 or a new tubular stitch row may be knitted using the heat-fusible yarn 8Y.

In S10, among the stitches forming the second joining stitch row 4, the stitch held at the BU is moved to the 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 . A joint portion 7 is formed by the first joining stitch row 3 and the second joining stitch row 4 . As shown in S11, the first jumping yarn 30 of the first joining stitch row 3 and the second jumping yarn 40 of the second joining stitch row 4 cross at a position between FD and BD. The crossover yarns 30 and 40 are portions of the joining stitch rows 3 and 4 that straddle the FD and the BD.

After S11, the knitted fabric 9 is removed from the needle bed while the shape of the stitches of the two joining stitch rows 3 and 4 is maintained by, for example, performing bag knitting using a draw thread. The pull-out yarn is a knitting yarn that is removed later, and is composed of a non-heat-fusible yarn.

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. On the other hand, when the knitting end portion 9E is formed by bind-off processing as in the conventional method of knitting a 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 time from the start of knitting to the end of knitting of the knitted fabric 9 may be more than doubled between the knitting method of the knitted fabric of this example and the conventional knitting method of the knitted fabric.

The state of the stitches in the vicinity of the joint portion 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. In FIG. 4, the portion knitted by the heat-fusible yarn 8Y (see FIGS. 2 and 3) is indicated by a thick line. As shown in FIG. 4 , a first knitted fabric portion 5 arranged on the upper side of the page and a second knitted fabric portion 6 arranged on the lower side of the page are connected by a joint portion 7 . In this example, the new first stitch row 10 and the new second stitch row 20 knitted by the heat-fusible yarn 8Y are regarded as parts of the first knitted fabric portion 5 and the second knitted fabric portion 6, respectively. . The orientation of the stitches of the first knitted fabric portion 5 and the orientation of the stitches of the second knitted fabric portion 6 are opposite to each other. In the joined portion 7, there is neither a double stitch nor a stitch continuous in the wale direction of the double stitch, unlike the joint portion in the bind-off process.

The joining portion 7 of this example is composed of 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 are formed alternately with 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 straddles 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 straddles the first knitted fabric portion 5 and the second knitted fabric portion 6 . The first jumping yarn 30 and the second jumping yarn 40 intersect at the boundary position between the joining stitch rows 3 and 4 . In FIG. 4, for convenience of explanation, two stitches adjacent in the knitting width direction in the joined 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 are shown in a state separated from each other. A stitch and jump yarns 30, 40 adjacent to the stitch are shown separated from each other. In the actual knitted fabric 9, since each stitch of the joining stitch rows 3 and 4 shrinks, the two stitches in at least a part of the sets consisting of two adjacent stitches, and in some cases, in all the sets, are contracted. in contact. In addition, the stitches and the jumping yarns 30, 40 are in contact with each other in at least some of the sets of the stitches and the jumping yarns 30, 40, and in some cases, in all of the sets.

The knitted fabric 9 of this example is neatly set by an iron or the like. The heat of the iron partially melts the heat-fusible yarn 8Y to fuse the stitches of the joining portion 7 and the stitches and the crossover yarns 30, 40 together. As a result, the heat-fusible yarn 8Y forming the joint portion 7 becomes difficult to move, and fraying of the stitches forming the joint portion 7 is suppressed. Here, the pull-out thread may be removed before the heat treatment, or may be removed after the heat treatment. If the drawing thread is water soluble, the drawing thread is dissolved and removed from the knitted fabric 9 when the knitted fabric 9 is washed before shipping.

A typical fusion point at joint 7 is indicated by a hollow arrow. The first stitch row 10, the second stitch row 20, the first joining stitch row 3, and the second joining stitch row 4 are composed of the heat-sealing yarn 8Y. Therefore, the contact portion between the stitch of the first stitch row 10 and the stitch of the first joining stitch row 3 is fused, and the contact portion between the stitch of the first stitch row 10 and the stitch of the second joining stitch row 4 is fused. are doing. Similarly, the contact portion between the stitch of the second stitch row 20 and the stitch of the first joining stitch row 3 is fused, and the contact portion between the stitch of the second stitch row 20 and the stitch of the second joining stitch row 4 is fused. are wearing

The first jumping yarn 30 and the second jumping yarn 40 are in contact with each other where the first jumping yarn 30 and the second jumping yarn 40 intersect. Therefore, the first crossover yarn 30 and the second crossover yarn 40 are fused together at the intersection. The intersection of the first jump yarn 30 and the second jump yarn 40 can be easily confirmed when the actual knitted fabric 9 is pulled. In addition, due to the contraction of both jump yarns 30 and 40, the stitches of the first joining stitch row 3 and the stitches of the second joining stitch row 4 are in contact with each other. Therefore, these stitches are also fused. In addition, due to shrinkage of the knitted fabric 9, the stitches of the first joining stitch row 3 and the first jumping yarn 30 or the second jumping yarn 40 contact, and the stitches of the second joining stitch row 4 and the first jumping yarn 30 or The portion where the second jump yarn 40 contacts is also fused. When the stitches and the jumping yarns 30, 40 are fused, the stitches of the stitch rows 10, 20 sandwiched between the stitches and the jumping yarns 30, 40 become difficult to move. Furthermore, due to shrinkage of the knitted fabric 9, stitches adjacent in the knitting width direction may also be fused together. Not all of the stitches in contact are necessarily fused. If the stretchability of the heat-fusible yarn 8Y is high, the number of contact points between adjacent stitches increases, and the strength of the joint 7 increases.

In the present example, all the stitches forming the joining stitch rows 3 and 4 are back stitches that are pulled out from the old stitches from the front side to the back side of the paper surface. A stitch usually tends to curl in the direction in which it is pulled out from the old stitch. 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 surface tend to curl to the front side of the paper surface. If all the stitches constituting the joining stitch rows 3 and 4 are front 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 surface. be worn. In this case, the feel and appearance of the joint 7 may be impaired. On the other hand, as in this example, if all the stitches forming the joining stitch rows 3 and 4 are back stitches, the first knitted fabric portion 5 and the second knitted fabric portion 6 of those back stitches curl toward the front side of the paper surface. restrain from doing. As a result, the first knitted fabric portion 5 and the second knitted fabric portion 6 are connected two-dimensionally, and the feel and appearance of the joint portion 7 are less likely to be impaired. Here, not all the stitches forming the joining stitch rows 3 and 4 may be back stitches. For example, if 50% or more of all the stitches constituting the first joining stitch row 3 and all the stitches constituting the second joining stitch row 4 are back stitches, the first knitted fabric portion 5 and the second The knitted fabric portion 6 is connected two-dimensionally. The higher the ratio of back stitches, the better. The backstitch ratio is, for example, 70% or more, or even 90% or more.

The joint 7 provided with the fused state described above has a predetermined stretchability. This is because the first jumping yarn 30 and the second jumping yarn 40 spanning between the first knitted fabric portion 5 and the second knitted fabric portion 6 at the joint portion 7 allow movement of the knitted fabric 9 in the knitting width direction. is. If the stretchability of the heat-fusible thread 8Y is high, the stretchability of the joint portion 9 is further improved.

<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. A needle-free state is a state in which an empty needle is arranged between two adjacent stitches.

The number of groups of 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-sealing yarn 8Y at the joint 7 increases, so the strength of the joint 7 increases. On the other hand, if the number of groups is large, there is a risk that the joint portion 7 will become too thick or the stretchability of the joint portion 7 will be impaired. Therefore, the upper limit of the number of groups is 6.

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 knitwear. Further, the knitting method of the knitted fabric of the present invention can also be used to prevent fraying at the end portion of a tubular knitted fabric. For example, an example of preventing fraying at the terminal end of a collar will be briefly described. While knitting the collar, a branched knitted fabric portion branching from the middle of the wale direction of the collar is knitted. The branched knitted fabric part is enough for one course. Next, the collar is knitted to 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, and the terminal end portion of the collar and the branched knitted fabric portion are heat-fused by the knitting method of the knitted fabric of the present invention. Joined by thread. By fusing the heat-fusible thread with an iron or the like, fraying prevention at the end of the collar is completed. In addition, when the branch knitted fabric portion is knitted in the middle of the main knitted fabric portion and the main knitted fabric portion and the branch knitted fabric portion are joined by the knitting method of the knitted fabric of the present invention, for example, belt loops for pants can be easily formed. can also
