Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the construction of the end of a knitted fabric such as socks with fingers or socks without fingers, gloves, leg warmers, tights, spats, wristbands, supporters, belly bands, and underwear. In particular, the present invention can solve the problem at the end of the tubular portion of a knitted fabric knitted in a tubular shape that requires elasticity.

[0002]

2. Description of the Related Art When knitting socks and gloves, which are examples of a tubular knitted fabric, with a flat knitting machine, knitting is performed from a toe portion or a fingertip portion to knit a tubular knitted fabric, and a leg insertion port which is a terminal portion thereof. Some of them are edge-treated at the peripheral edge or the peripheral edge of the hand insertion opening. At this time, as an end processing method, an overlock is applied, rake sewing is performed, or one of two adjacent loops is moved to the other loop side to be overlapped, and this overlap is performed. After repeating the procedure of forming a new loop in the set portion and performing a bind-off process, or supplying a heat fusion yarn to the end of the knitted fabric to form a knitted fabric portion with the heat fusion yarn, Is removed from the knitting needle, and the knitted fabric portion made of the heat-fusible yarn is heated and fused to prevent fraying.

[0003] However, when the end portion of the tubular knitted fabric is processed by overlock as described above, the appearance is deteriorated, and when the process is performed by scoop sewing, problems such as bulkiness are caused. . In addition, as described above, one of the two adjacent loops is moved to the other loop side and overlapped, and the procedure of forming a loop in the overlapped portion is repeatedly performed, and the bind-off processing is performed. After being knitted off from a knitting needle or supplying a heat-fusing yarn to form a knitted fabric portion with the heat-fusible yarn, the knitting needle is wiped off, and the knitted fabric portion with the heat-fused yarn is heated and fused to be loosened. In the case of a product that is stopped, there is a problem that the peripheral portion of the opening of the cylindrical portion becomes hard, lacks elasticity, impairs a feeling of wearing, and lowers the commercial value.

[0004]

Therefore, as described in Japanese Patent Application Laid-Open No. 9-188945, the applicant of the present application superimposes adjacent loops at the end of a tubular knitted fabric, and The elastic yarn is supplied to the formed loop to form a new loop, so that the loop is wiped off from the knitting needle, the binding process is performed, and the end processing is performed, so that the elasticity of the end opening of the tubular knitted fabric can be improved. Suggested ones.

[0005] However, in the above-mentioned bind-off processing, at the start of bind-off, a ground yarn having the same thickness is doubled and an elastic yarn is supplied to the double loop to form a new loop. Then, in the bind-off process, a loop made of the elastic yarn and a loop made of the adjacent ground yarn are overlapped, that is, a loop having a different thickness is overlapped to form a new loop made of the elastic yarn. Therefore, the thickness of the entire double loop differs between the start of the bind-off processing and the bind-off processing thereafter.
There was a problem that the loop was likely to fall off due to the difference in the thickness of the yarn.

That is, in general, when the thickness of the yarn is changed in the middle of knitting, dropouts are likely to occur. This is likely to cause a drop, and the knitting efficiency is reduced. Further, since only the bind-off processing applied to the end portion of the tubular knitted fabric is performed with the elastic yarn, at the start of the bind-off processing, the elastic yarn is supplied to the loop of the double-laid ground yarn to supply the elastic yarn. When the elastic yarn is supplied to the double loop to form a new loop by the elastic yarn, there is a problem that the elastic yarn is cut off due to a large resistance.

[0007] The present invention has been proposed in view of the above-mentioned problems, and has excellent stretchability at the end of a knitted fabric requiring stretchability, has a good feeling of wearing, and can improve the commercial value while suppressing the bind-off. It is an object of the present invention to provide a knitted fabric capable of improving workability.

[0008]

In order to achieve the above object, according to the first aspect of the present invention, at the end of the knitted fabric, one end of the knitted fabric main body knitted with ground yarn is attached with an elastic yarn.
The continuous knitting of the elastic knitted fabric portion or more is performed, and adjacent loops are overlapped with the elastic yarn, and a new loop is formed in the overlapped loop, so that the loop is wiped off from the knitting needle. It is configured to perform partial processing.

As the elastic yarn, a rubber yarn made of polyurethane or rubber (for example, Toyobo Espal having polyurethane elastic yarn as a core yarn) or a stretchable elastic yarn such as polyurethane elastic yarn as a core yarn is used. Surrounded with a stretchable knitting yarn such as a wooly nylon yarn as an auxiliary thread (FTY), a stretchable knitting yarn such as a wooly nylon yarn, and a rubber yarn and a polyurethane elastic yarn made of polyurethane, rubber, or the like Combined with a core yarn made of a stretchable elastic yarn and covered with a stretchable knitting yarn such as a wooly nylon yarn as an additional yarn, and a rubber yarn made of polyurethane or rubber and a wooly nylon yarn. And a combination with a stretchable knitting yarn.

According to a second aspect of the present invention, in the first aspect of the present invention, the knitted fabric main body is formed of a tubular knitted fabric, and an elastic yarn is inserted through the knitted fabric main body and circulated to form the elastic yarn. Thus, the elastic knitted fabric portion to be continuously knitted is knitted on the knitted fabric main body and the bind-off processing is performed. Inserting an elastic thread through a knitted fabric body of a tubular knitted fabric and circling it means inserting an elastic thread such as a rubber thread into a knitted fabric of a leg insertion part such as a sock, and circling the inside of the tubular knitted fabric a plurality of times. It can reinforce the elasticity of the leg insertion part such as socks.

According to a third aspect of the present invention, there is provided a method for treating an end portion of a knitted fabric, wherein in a weft knitted fabric knitted with knitting needles of a needle bed, a knitted fabric body knitted with ground yarn is used. An elastic yarn is supplied to the last loop, and at least one new loop is continuously knitted by the elastic yarn to form an elastic knitted fabric portion. Then, the final loop in the elastic knitted fabric portion is overlapped with an adjacent loop. In addition, a new loop is formed on the overlapped loop with the elastic yarn, and the new loop is overlapped with an adjacent loop to form a new loop on the overlapped loop with the elastic yarn. The loop is removed from the knitting needle while sequentially performing eye treatment.

So-called "five-body" knitted into one tubular knitted fabric
The part 7 is further knitted to the arch part 8.

After forming an arch part 8 forming a constriction from the "five-body" part 7, a heel part 9 and an ankle part 10, it is knitted on the upper end side of the tubular part by 1 × 1 rib knitting. A leg insertion port portion 14 having a leg insertion port 11 is knitted. Then, at the end of the knitted fabric for knitting the leg insertion opening portion 14, at the knitting end of the knitted fabric body knitted with ground yarn,
One or more elastic knitted fabric portions are continuously knitted with an elastic yarn, and adjacent loops are overlapped with the elastic yarn, and a new loop is formed in the overlapped loop, so that the loop is wiped off from the knitting needle. The end processing is performed by eye processing.

In order to reinforce the elastic force of the leg insertion port portion 14, this elastic thread uses an elastic thread inserted through the leg insertion port portion 14 knitted with ground yarn. Rubber yarn or the like (in the present embodiment, a rubber yarn having a polyurethane elastic yarn as a core yarn, and Toyobo Espal is used) is formed on the knitted fabric main body knitted with the ground yarn of the mouth portion 14. Through the tubular knitted fabric a plurality of times, and continuously stretch the elastic yarn from the end of knitting of the knitted fabric main body of the leg insertion opening portion 14 by the same 1 × 1 rib knitting as it is. We organize.

It is preferable to knit an elastic knitted fabric portion of a course or more, more preferably 1 and 3/4 course.

Further, when the knitted fabric body is knitted by rib knitting or flat knitting, when the flat knitting is performed, the elastic knitted fabric portion is knitted at least one stitch. More than a course is preferable, and it is more preferable to form two courses. Then, after knitting the elastic knitted fabric portion with the elastic yarn, the bind-off process is continuously performed by the elastic yarn, and the knitting of the elastic knitted fabric portion knitted by rib knitting is performed. The loop at the end of knitting is overlapped with the adjacent loop, and a new loop is formed with the elastic yarn on the overlapped loop, thereby performing a bind-off process of removing the loop from the knitting needle.

In the present embodiment, the bind-off processing is performed by the rib bind-off processing, which directly binds off each of the front knitting loop and the back knitting loop at the end portion of the rib knitted fabric. In addition, as the elastic yarn,

Next, as shown in FIG. 4 from the state of FIG.
In the rib knitted fabric on the back side of the sock hooked over the front and rear knitting needles, the loop hooked on the transfer empty needles B, D, F,. · Transfer to DF · · · Also, the loop hooked on the transfer empty needles A · C · E · · · of the front needle bed in the ribbed fabric on the front side of the sock Transfer to knitting needles A, C, E, etc.

FIG. 5 to FIG. 7 show a part of the procedure of the bind-off processing of the rib knitted fabric on the back side of the sock. FIG. 5 shows the knitting needle of the front needle bed on the rib knitted fabric side on the back side of the sock. After transferring the loop hooked on K to the transfer empty needle J of the rear needle bed, as shown in FIG. 6, the loop transferred to the transfer empty needle J of the rear bed is moved to the front side. It is transferred to the knitting needle J of the bed so that the knitting needle J of the front bed is in a state where two loops are hooked.

Then, as shown in FIG. 7, when a new loop is formed by an elastic thread on the front knitting needle J on which the two loops are hooked, the knitting needle K of the upper rear bed in FIG. 3 is located. The folded loop is in a state where the bind-off processing is performed, and the loop of the elastic yarn newly formed on the front knitting needle J is then moved to the state shown in FIG.
As shown in FIG. 5, the loop of the rib knitted fabric on the back side of the sock is shifted from the center to the left side in the figure by repeating the procedure of FIGS. It is being done.

Next, the procedure of the bind-off processing of the rib-knitted fabric on the front side of the sock is shown in FIGS. 8 to 21. As shown in FIG. 8, in the state shown in the lower part of FIG. At the left end, a new loop is formed by an elastic thread on the knitting needle A of the front bed, and as shown in FIG. 9, a loop is further formed on the transfer empty needle A of the rear bed, and as shown in FIG. The loop of the empty needle A for transfer on the side bed is transferred to the knitting needle A on the front side, and two loops are hooked on the knitting needle A on the front bed.

Then, the two loops hooked on the knitting needle A of the front bed are transferred to the transfer empty needle A of the front bed, and supplied to the transfer empty needle A of the front bed as shown in FIG. After forming a new loop by threading, the loop is transferred to the knitting needle A of the rear bed and superimposed as shown in FIG. As shown in FIG. 13, a new loop is formed on the knitting needle A of the rear bed where the loop is doubly hooked, and this loop is transferred to the empty needle A for transfer of the front bed as shown in FIG. By moving the rear needle bed to the left by one pitch as shown in FIG. 15, the transfer empty needle of the front bed is moved to the right by one pitch, and in FIG. 16, the transfer empty needle A of the front bed is moved. The loop is transferred to the rear knitting needle B so that two loops are hooked on the rear knitting needle B.

When a new loop is formed on the knitting needle B of the rear bed in FIG. 17, the loop located at the transfer empty needle A of the lower front bed in FIG. . At this time, the loop shown in FIGS. 8 to 12 is formed to secure the yarn length because the portion becomes a crossover portion between the front body and the back body.

Then, the loops of the rib-knitted fabric on the front side of the sock are bound from left to right in the figure by repeating FIG. 13 to FIG. 17 as appropriate, and the loops are removed from the flat knitting machine. It goes. Further, when the loop reaches the position of the knitting needle T of the rear bed, as shown in FIG. 18, a new loop is formed in the transfer empty needle T of the front bed, and the transfer empty needle T of the front bed is formed.
19, the knitting needle T of the rear bed as shown in FIG.
After forming a new loop as shown in FIG. 20, the loop formed on the knitting needle T of the rear bed is transferred to the empty needle T for transfer of the front bed, and the rib knitted fabric on the front side is formed. Is completed.

Next, in order to perform the bind-off processing of the remaining half of the back side rib knitted fabric, the loop hooked to the knitting needle T of the right end front bed in the back side rib knitted fabric shown in FIGS. The same bind-off processing is repeated as appropriate to complete the bind-off processing of the rib knitted fabric on the back side, and the sock 1 is completed. Socks 1 formed as described above
In the 1 × 1 rib knitted fabric forming the leg insertion opening portion 14, a 1 × 1 rib knitted elastic knitted fabric portion of the same knitted fabric is continuously knitted as it is from an end portion of the knitted fabric main body in the 1 × 1 rib knitted fabric. Since the loop of the elastic knitted fabric portion is subjected to the bind-off processing as it is, the bind-off-treated portion also expands and contracts by following the elasticity of the rib knit by the elastic yarn.

Since the elastic knitted fabric is knitted at least one stitch, the thickness of the entire double loop may differ between the start of the bind-off processing and the bind-off processing thereafter. This eliminates the conventional problem that the loop is likely to fall off due to the difference in the thickness of the yarn when performing the bind-off processing. Furthermore, since the bind-off processing by the elastic yarn is performed continuously from the elastic knitted fabric portion, the resistance when supplying the elastic yarn to the double loop at the start of the bind-off processing can be reduced as compared with the conventional case. Therefore, the conventional disadvantage that the elastic yarn is easily broken can be solved.

When one or more courses of the elastic knitted fabric are knitted, a double loop to be overlapped when performing the bind-off processing is formed by elastic yarns of the same thickness in one course. , Less loop dropout,
The workability of the bind-off processing is further improved. Moreover, as in the case of the present embodiment, when the knitted fabric main body is knitted by the rib knitting and the bind-off processing is performed by the rib bind-off processing, 1
When knitting the elastic knitted fabric part with 3/4 course, not only can the loop fall off, but also the bind-off processing can be started from the middle part of the tubular knitted fabric, so that the appearance is beautiful and good. Therefore, the elasticity of the periphery of the insertion opening can be further improved.

Since the loop of the elastic knitted fabric portion is directly bound off, the elasticity of the elastic yarn and the elasticity at the insertion hole of the foot can be ensured. As described above, the local strong tightening at the insertion port of the foot is eliminated, and the feeling of wearing can be improved. Further, in the present embodiment, the elastic knitted fabric portion continuously knitted on the knitted fabric main body is knitted by using the elastic yarn that is inserted into the knitted fabric main body in the leg insertion opening portion 14 and circulates. Since it is configured to perform the stitching process, it is not necessary to separately provide a yarn feeder for the stitching process, and the number of knitted fabrics that can be knitted by one knitting machine is reduced by the number of the yarn feeders for the stitching process. Can increase the productivity, and furthermore, it is possible to reduce the amount of thread coming out of the leg insertion opening 11 which is the end of the tubular knitted fabric, and to reduce the elasticity at the start of knitting the elastic knitted fabric. Thread can be prevented from coming off.

In the above embodiment, a flat knitting machine having a structure in which a knitting needle for knitting and an empty needle for transfer are slidably mounted between sinkers is used. The present invention can be applied to a transfer jack bed in which a jack is slidably accommodated, and the present invention can be applied to a flatbed knitting machine having four so-called beds in which a pair of front and rear beds are provided up and down. Of course, you can.

In the above embodiment, the leg insertion port portion 14 is formed by 1 × 1 rib knitting.
The knitted fabric of the leg insertion opening portion 14 may be rib knitting such as 2 × 1 or 2 × 2, so-called “wide rib knitting”, or may be knitted by flat knitting. In the embodiment, the knitted fabric body is knitted by rib knitting, and the bind-off process is performed with the rib bind-off, but for example, the knitted fabric body made of flat knit is also subjected to the bind-off process with the rib bind-off, The elastic knitted fabric part is knitted at least one stitch, preferably one or more courses, and more preferably knitted elastic knitted fabric parts of 1 and 3/4 courses.

Also in this case, when one or more courses of the elastic knitted fabric are knitted, double loops to be overlapped when performing the bind-off processing can be formed by elastic yarns having the same thickness. In addition, the dropout of the loop can be reduced, and the workability of the bind-off processing can be further improved. Moreover, knitting the elastic knitted fabric portions of the 1 and 3/4 courses can reduce the dropout of the loop and start the bind-off process from the middle portion of the tubular knitted fabric, similarly to the above-described embodiment. The appearance can be beautiful and good, and the elasticity of the periphery of the insertion opening can be further improved.

Further, when the knitted fabric main body is knitted by rib knitting or flat knitting, the elastic knitted fabric portion is knitted by one or more stitches even when flat knitting is performed. The above is preferable, and it is more preferable to form two courses. Hereinafter, as a second embodiment, a case in which a knitted fabric body is knitted by flat knitting and a flat knitted binding process is performed will be described with reference to FIGS.

FIG. 22 shows a knitting course of flat knitting. For convenience, the knitted fabric on the back side of the sock is displayed in the upper row, and the knitted fabric on the front side of the sock is displayed in the lower row. In FIG. 22, knitting is performed by knitting from the left end of the lower needle bed, moving to the right end of the upper needle bed, and making a single turn at the left end of the upper stage, and knitting the knitted fabric main body with ground yarn. Thereafter, an elastic knitted fabric portion that is continuous with the knitted fabric body is knitted by using the elastic yarn that has been inserted into the knitted fabric body, and the elastic knitted fabric portion is formed by a lower needle in FIG. Two courses are formed from the left end of the roux bed to the left end position of the upper needle bed.

FIGS. 23 to 25 show the procedure of the bind-off processing of the knitted fabric on the front side of the sock. FIG. 23 shows a loop hooked on the knitting needle A of the front needle bed in the knitted fabric on the front side of the sock. Is transferred to the transfer empty needle B of the rear needle bed, and as shown in FIG. 24, the loop transferred to the transfer empty needle B of the rear bed is transferred to the knitting needle B of the front bed. Two loops are hooked on the knitting needle B of the front bed.

Then, as shown in FIG. 25, when a new loop is formed by an elastic thread on the front knitting needle B on which the two loops are hooked, the knitting needle A of the lower front bed shown in FIG.
The loop that was located in is turned off
Next, the loop of the elastic yarn newly formed on the front knitting needle B is transferred to the transfer empty needle C of the rear bed as shown in FIG. 25, and the procedure of FIGS. The loop of the knitted fabric on the front side is bound from left to right in the figure.

Next, the procedure of the bind-off processing of the knitted fabric on the back side of the sock is shown in FIGS. 26 to 31. As shown in FIG. 26, the knitting needle T of the front bed is elastically threaded at the right end of the knitted fabric on the back side. A new loop is formed, and this loop is transferred to the transfer empty needle T of the front bed, and the loop of the transfer empty needle T of the front bed is transferred to the rear knitting needle T as shown in FIG. Then, two loops are hooked on the knitting needle T of the rear bed.

Then, as shown in FIG. 28, the yarn is fed to two loops hooked on the rear knitting needle T to form a new loop, and then, as shown in FIG. The transfer loop is transferred to the transfer empty needle S, and as shown in FIG. 30, the transferred loop is transferred to the knitting needle S of the rear bed and superposed. When a new loop is formed as shown in FIG. 31 on the knitting needle S of the rear bed in which the loop is doubly hooked, the loop located on the knitting needle T of the upper rear bed in FIG. It will be in the state that was done.

29 to 31 are repeated as appropriate, so that the loop of the knitted fabric on the back side of the sock is bound from right to left in the figure, and the loop is removed from the flat knitting machine. Go. In the second embodiment, the elastic knitted fabric portion is knitted at least one stitch similarly to the first embodiment, so that the bind-off process is started at the start of the bind-off process and thereafter. This eliminates the conventional problem that the yarn thickness of the entire double loop does not differ, and the loop tends to fall off due to the difference in the yarn thickness when performing the bind-off processing.

Further, since the bind-off treatment using the elastic yarn is performed continuously from the elastic knitted fabric portion, the resistance when supplying the elastic yarn to the double loop at the start of the bind-off treatment is reduced as compared with the conventional case. Since it is possible to reduce the number of the elastic yarns, it is possible to solve the conventional problem that the elastic yarn is easily broken. Further, when knitting the elastic knitted fabric portion in one or more courses, the double loop to be overlapped when performing the bind-off processing is formed by elastic yarns of the same thickness in one course, so that the loop The falling off is reduced, and the workability of the bind-off processing is further improved.

Moreover, when the elastic knitted fabric portion is knitted in two courses, not only can the loop fall off, but also the elasticity of the peripheral portion of the insertion opening can be further improved. In addition,
The end treatment of the knitted fabric of the present invention is not limited to the socks with fingers as in the above-described embodiment, and it is the end of knitting of the tubular supporter as shown in FIG. 32 as well as the round socks. It may be carried out in the opening 22 or, as shown in FIG. 33, in the neck part 32 of the round neck sweater 31 or the part where the knitting ends in the opening such as the cuff part 33 and the hem part 34. Alternatively, as shown in FIG. 34, the knitting may be carried out on one of the knitting end sides in the opening of the waistline portion 42 or the ankle portion 43 of the underwear 41.

As shown in FIG. 35, in a supporter 51 to be attached to the ankle, which has an open heel portion, an end-side end portion 52 at the opening of the heel portion.
The end treatment of the present invention may be applied to the knitting end side opening (the lower opening 53 on the toe side in FIG. 35) among the upper and lower ends. In addition, it goes without saying that the present invention can be applied to a tubular knitted fabric such as gloves, tights, spats, a wristband, and a belly band.

In addition, in the above-described embodiment, the bind-off treatment is performed from one end of the needle bed to the other end. Needless to say, the binding processing can be sequentially performed from the place.

[0048]

As described above, according to the present invention, at one end of a knitted fabric, at least one elastic knitted fabric portion is continuously knitted with an elastic yarn at an end of a knitted fabric body knitted with ground yarn. At the same time, adjacent loops are overlapped by the elastic yarn, and a new loop is formed on the overlapped loops, so that the loops are wiped off from the knitting needles. The yarn thickness of the entire double loop does not differ between the start of processing and the bind-off processing thereafter, and when performing bind-off processing, loops are likely to fall off due to the difference in thread thickness. Can be solved.

Further, since the bind-off treatment using the elastic yarn is performed continuously from the elastic knitted fabric portion, the resistance when supplying the elastic yarn to the double loop at the start of the bind-off treatment is reduced as compared with the conventional case. Since it is possible to reduce the number of the elastic yarns, it is possible to solve the conventional problem that the elastic yarn is easily broken. Further, in the present invention, the knitted fabric body of the knitted fabric is formed of a tubular knitted fabric, an elastic yarn is inserted through the knitted fabric main body and circulated, and by the elastic yarn,
When knitting the elastic knitted fabric portion to be continuously knitted on the knitted fabric main body and performing a bind-off treatment, an elastic yarn inserted through the knitted fabric main body in order to reinforce the elasticity of the knitted fabric main body. Since the knitting and the bind-off processing of the elastic knitted fabric portion can be performed by using this, it is not necessary to separately provide a yarn feeder for bind-off processing, and the number of knitted fabrics that can be knitted by one knitting machine is used. Can be increased by the amount that can reduce the number of the yarn feeders for bind-off processing, so that the productivity can be improved, and the thread is less likely to flow out at the leg insertion port 11 which is the end of the tubular knitted fabric. The elastic yarn can be prevented from coming off when the knitting of the elastic knitted fabric portion is started.

As described above, according to the present invention, at one end of a knitted fabric, at least one elastic knitted fabric portion is continuously knitted with an elastic yarn at an end of a knitted fabric body knitted with ground yarn. At the same time, with the elastic yarn knitting the elastic knitted fabric portion , adjacent loops are superimposed, and a new loop is formed in the superimposed loop so that the loop is wiped off from the knitting needle. Since the binding is performed, the yarn thickness of the entire double loop is not different between the start of the binding processing and the binding processing thereafter. The conventional disadvantage that the loop is likely to fall off can be solved.

Further, since the bind-off treatment using the elastic yarn is performed continuously from the elastic knitted fabric portion, the resistance when supplying the elastic yarn to the double loop at the start of the bind-off treatment is reduced as compared with the conventional case. Since it is possible to reduce the number of the elastic yarns, it is possible to solve the conventional problem that the elastic yarn is easily broken. Further, in the present invention, the knitted fabric main body of the knitted fabric is formed of a tubular knitted fabric, and
The elastic yarn is orbiting and inserted into the tubular knitted fabric body is knitted by the elastic yarn After orbiting, while knitting the tubular knitted fabric 1 stitches or more elastic knitted fabric portion continuous knitting the body In the case where the binding processing is performed, the knitting of the elastic knitted fabric portion and the binding processing are performed by using an elastic thread inserted through the knitted fabric main body to reinforce the elastic force of the knitted fabric main body. This eliminates the need to provide a separate yarn feeder for bind-off processing, and increases the number of knitted fabrics that can be knitted with one knitting machine by the amount that can reduce the yarn feeder for bind-off processing. The knitting of the elastic knitted fabric can be improved, and the thread can be prevented from coming off at the leg insertion port 11 which is the end of the tubular knitted fabric. Can also be prevented.
