Description

  The present invention knitted clothing and the like to be worn on the human body as a non-sewn tubular knitted fabric, and formed a heel at a portion corresponding to a joint or the like that joins the tubular knitted fabric to improve the feeling of wear. The present invention relates to a knitting method and a knitted fabric of a tubular knitted fabric having a heel for performing.

  2. Description of the Related Art Conventionally, a garment worn on a human body has a generally cylindrical shape such that a front part and a rear part swell outward. In a flat knitting machine that includes at least a pair of opposed needle beds in the front and rear and is capable of transferring and racking between the front and back needle beds, a tubular knitted fabric can be manufactured without sewing. If the knitting yarn is supplied so as to go around the front and back knitted fabrics with the knitted fabrics on the front and back needle beds, respectively, the front and back knitted fabrics are connected at both ends of the knitting width, and the whole is shaped like a cylinder. A knitted fabric can be manufactured without sewing (for example, refer patent documents 1-3). These Patent Documents 1 to 3 knitted a tubular knitted fabric without sewing while forming a gusset between a body part and a sleeve in a knit product worn on the upper body of a human body such as a sweater. Techniques to do this are disclosed. It is also possible to form a knit product to be worn on the lower body of a human body such as pants without sewing on a tubular knitted fabric while forming a heel between both legs (for example, see Patent Document 4).

  FIG. 10 shows the shape of the knitted fabric knitted by the flat knitting machine in the case of basic flat knitting. When the carriage moves in the longitudinal direction of the needle bed and the knitting action of the knitting needle is performed, a series of stitch loops is formed in the course direction indicated by C. Each stitch loop knocks over the stitch loop locked to the knitting needle before passing through the carriage so as to be orthogonal to the course direction and to be connected to the direction of the wale indicated by W. As a basic property of such a knitted fabric, it is known that it is easy to stretch in the course direction and difficult to stretch in the wale direction. The ridges formed by the prior arts of Patent Documents 1 to 4 are formed in the process of continuously joining the tubular knitted fabrics in the front-rear direction, and each tubular knitted fabric is formed at the boundary between the tubular knitted fabrics. A bind-off is formed in the course direction of the ground. In Patent Document 2, knitting is performed such that a transition yarn is generated so that a hole is not formed in a connecting portion between cylindrical knitted fabrics and there is elongation and tensile strength is increased.

  A technique for knitting a knitted fabric as a heel is also known (see, for example, Patent Document 5). Claim 1 of Patent Document 5 includes a non-sewn knit pant with a body portion formed first, and a crotch portion at the center. In the part, “circular knitting while interrupting the left and right stitches to form a substantially triangular additional portion (17a)”, “rotating knitting while holding the stitches gradually from the left and right outside to the inside and reverse triangle Forming an additional portion (17b) of the shape ”,“ When the crotch portion (15) is then knitted circularly, the inner portion of the crotch portion (15) is increased while maintaining the number of stitches at the lower end of the additional portion (17b). Forming part (17c) ".

  In the manufacture of garments by sewing such as underwear, a technique is used that creates a prototype that cuts the fabric based on three-dimensional cutting. In such draping, an independent fabric is applied to the heel portion. Regarding pantyhose and tights, a technique for sewing a gusset to a joint portion of a tubular knitted fabric is also known (see, for example, Patent Document 6).

International Publication No. 01/088243 Pamphlet International Publication No. 2002/063085 Pamphlet International Publication No. 03/031707 Pamphlet International Publication No. 2004/063447 Pamphlet Japanese Patent No. 3403720 JP-A-9-78309

  If the techniques disclosed in Patent Documents 1 to 4 are used, a three-dimensional knitted product having a heel at the joint between a sleeve such as a sweater and a body and a crotch such as pants can be sewn without sewing. Can be manufactured. In a knitted product having these heels, if the heel portion is sufficiently removed, the wearer can feel a sufficient space. However, since the knitting is linear, the outline does not follow the human body, and it is not preferable in terms of appearance to form a large heel portion. In movements of arms and legs in sports and the like, further clearance and elongation may be required. In the technique of Patent Literature 2, a yarn can be added to the heel portion to reinforce, but no extension can be obtained. In the technique of Patent Document 5, since the heel is extended to the inside of the leg portion, the portion that becomes the heel becomes large.

  Moreover, in the techniques of Patent Documents 1 to 5, although the shape of the heel is the same between the front side and the rear side, the human body has different sizes in the front and rear. For example, in the upper body, the front chest is larger than the rear, and the arm joints are formed to move toward the chest within a large angle range. In the lower body, the rear buttocks are larger than the front. As a function of the bag for forming clothes to be worn on the human body, it is expected to absorb a difference in the shape of the front and back of the human body and provide a space. However, when the heel is divided into a front side and a rear side with a flat knitting machine and knitted into a cylindrical shape, the front-rear direction becomes the wale direction. Since the knitted fabric is difficult to extend in the wale direction, it is difficult to have a space in the front-rear direction. As in the technique of Patent Document 6, when a crease is formed from another fabric and added to a tubular knitted fabric, an appropriate shape based on draping can be made. As a fabric, it must be sewn, and it takes time rather than no sewing.

  An object of the present invention is to provide a knitting method and a knitted fabric of a tubular knitted fabric having a heel that has a space in the front and rear and can obtain an outline along the human body without sewing.

The present invention is a flat knitting machine having at least a pair of opposed needle beds on the front and back and capable of transferring and racking between the front and back needle beds, and connecting the knitted fabrics knitted respectively on the front and back needle beds at both ends. On the other hand, a method of knitting a tubular knitted fabric having ridges without sewing by forming a knitted fabric at the joint portion,
A plurality of tubular knitted fabrics to be joined are each knitted from the tip to the vicinity of the joined part,
In the vicinity of the joint part, the knitting of the knit fabric has begun,
Knit the knit fabric so that the front side and the rear side have different shapes,
While joining the tubular knitted fabrics via the knitted knitted fabric,
The knitted fabric is different in the number of courses knitted on the front side and the rear side,
One side of the tubular knitted fabric to be joined to the side with a small number of courses among the knitted fabrics of the front side and the rear side is formed with a dart in the middle of the width direction, and the knitting width is changed between the front side and the rear side. This is a method for knitting a tubular knitted fabric having ridges, characterized in that it is matched to the other side of the tubular knitted fabric joined to the side having the larger number of courses.

Further, in the present invention, one of the front and rear side knitted fabrics includes a portion where the knitting width decreases and a portion where the knitting width becomes constant,
The other of the knitted fabrics of the front side and the rear side is so that the knitting width decreases.
It is characterized by knitting each.

  In the present invention, the ratio between the number of courses knitted on at least one of the front and rear side knitted fabrics and the number of courses knitted on the tubular knitted fabric of the portion joined to the knitted fabrics, The knitted fabric side is smaller than 1: 1.

  The present invention is characterized in that the ratio of the number of courses for knitting the knit fabric and the tubular knitted fabric is different between the front side and the rear side of the knit fabric.

In the present invention, the tubular knitted fabric is worn on the lower body of a human body,
The knitted knitted fabric is formed at a crotch portion between both legs of the tubular knitted fabric, and the number of courses on the back side is larger than the number of courses on the front side of the knitted knitted fabric.

  Furthermore, the present invention is a knitted fabric manufactured by the above-described method for knitting a tubular knitted fabric having any one of the ridges.

  According to the present invention, using a flat knitting machine that includes at least a pair of opposed needle beds on the front and rear, and can transfer and rack between the front and back needle beds, the front and rear have a space and follow the human body. A tubular knitted fabric having such an outline ridge can be manufactured without sewing. The knitted fabric is different in the number of courses knitted on the front side and the rear side, and one side of the tubular knitted fabric joined to the side with a smaller number of courses among the front and rear side knitted fabrics has a width Since the dart is molded in the middle of the direction and the knitting width is matched with the other side of the tubular knitted fabric joined to the side having the larger number of courses among the front and rear side knitted fabrics, the tubular knitted fabric The direction of the stitches can be aligned at the front and rear connecting portions.

  Further, according to the present invention, one of the knitted fabrics of the front side and the rear side is knitted so as to include a portion where the knitting width is reduced and a portion where the knitting width is constant, so that there is sufficient clearance. Can be made.

  Further, according to the present invention, the ratio between the number of courses knitted on at least one of the front and rear side knitted fabrics and the number of courses knitted on the tubular knitted fabric of the portion joined to the heel knitted fabric, Since the knit fabric side is smaller than 1: 1, the inside of the knit fabric is recessed in an arch shape, and the outline can be formed along a human body that is not linear.

  Further, according to the present invention, the ratio of the number of courses for knitting the knit fabric and the tubular knitted fabric is made different between the front side and the rear side of the knit fabric, so that an arch-shaped depression is provided as necessary for clearance. Can be adjusted in both directions and before and after.

  Further, according to the present invention, the number of courses on the back side, which is the buttock side of the knit knitted fabric formed in the crotch part between both legs without sewing the pants worn on the lower body of the human body, is larger than the front side, It can be manufactured with a larger clearance on the buttock side.

  Furthermore, according to the present invention, a knitted fabric such as clothes to be worn on the human body is manufactured as a tubular knitted fabric having a heel without sewing using a flat knitting machine, and the front and rear shapes are changed to provide sufficient clearance. A good outline can be obtained.

  FIG. 1 shows a layout of a knitted fabric with pants 1 as an example of a knitted product formed by a knitting method of a tubular knitted fabric having a ridge as an embodiment of the present invention. The pants 1 generally includes a trunk portion 2 and leg portions 3. The trunk | drum 2 is knitted as one cylindrical knitted fabric. The leg 3 is formed in a cylindrical shape as the left and right leg 3L, 3R. The left and right leg portions 3L and 3R are joined to the body portion 2 with the collar portion 4 interposed therebetween.

  Such a tubular knitted fabric having a heel such as pants 1 has at least a pair of opposing needle beds in front of and behind the mouth as viewed from the front, and is capable of transferring and racking between the front and back needle beds. Can be knitted with a knitting machine. A tubular knitted fabric can be formed by connecting the knitted fabrics knitted by the front and back needle beds at both ends. When using a two-bed flat knitting machine in which a pair of needle beds are provided at the front and back, for example, every other knitting needle is knitted on each needle bed, and a knitted fabric is knitted on the needle bed. This knitting needle is used as an empty needle, and is used for knitting the back stitch and rib knitting to the knitted fabric knitting the front stitch on the opposing needle bed, and for locking when transferring. When using a four-bed flat knitting machine in which the needle bed is provided in two stages at the top and bottom, the front knitted fabric is knitted with the knitting needles of the lower front needle bed and the upper rear needle bed, and the rear knitted fabric is similarly formed. Since the knitting needles of the lower back needle bed and the upper front needle bed can be used for knitting, it is not necessary to provide empty needles as in the two-bed flat knitting machine, and the surface of links, garters, ribs, etc. It is possible to knitting a tissue pattern in which the knitted fabric and the back stitch are mixed, or to move the stitches of the front and rear knitted fabrics in the course direction and join them together. If the knitted fabric is formed at the joint portion of the tubular knitted fabric, the tubular knitted fabric having the heel can be knitted without sewing.

  When the pants 1 shown in FIG. 1 is manufactured, for example, when worn on the human body, the front knitted fabric is knitted so that the front stitches are knitted, and the rear knitted fabric is knitted with the rear needle beds. Organize as you like. FIG. 1 (a) shows the front knitted fabric, and FIG. 1 (b) shows the rear knitted fabric. The knitted fabric of the heel part 4 is different in shape between the front knitted fabric 4F and the rear knitted fabric 4B, and the rear knitted fabric 4B is knitted more than the front knitted fabric 4F. Increase the number. That is, on the front side shown in FIG. 1 (a), a front body composed of front body portions 2LF, 2RF divided into left and right sides and front sides 3LF, 3RF of left and right leg portions 3L, 3R, and the front side Knit knitted fabric 4F. In the rear side shown in FIG. 1 (b), a rear body composed of rear trunks 2LB, 2RB and left and right leg portions 3L, 3R shown separately on the left and right sides, and rear The side knitted fabric 4B is knitted.

  The knitting of the portion shown in FIG. 1 can be performed in five sections S1 to S5. The knitting of the buttocks 4 is performed in the sections S2 to S4.

  First, in the section S1, the left and right leg portions 3L and 3R serving as a plurality of tubular knitted fabrics to be joined are knitted as independent tubular knitted fabrics from the tip to the vicinity of the joined portion. Each leg 3L, 3R is knitted into a cylindrical shape while connecting the front side 3LF, 3RF and the rear side 3LB, 3RB on both sides of the width. Although the heel part 4 is not knitted, abandoned knitting as described later may be performed.

  In section S2, it becomes near the junction part of leg parts 3L and 3R, and set-up of the knitted fabric used as heel part 4 is also started. If the flat knitting machine used for knitting is provided with a movable sinker having a function of pushing down the knitted fabric downward, or a mechanism capable of partially lowering the knitted fabric, the leg 3L , 3R can be knitted from the middle of knitting. If discard knitting is performed together with the knitting of the legs 3L and 3R, the heel part 4 can be pulled down together with the legs 3L and 3R downwardly through the knitted fabric.

  In the knitting in the section S2, the knitting of the body 3 eyes 1 and the body 1 eye 1 eye is combined, and at the same time, the heel part 4 is also formed to form the loose parts 5F and 5B. The rear gentle part 5B is knitted as a straight part with a constant knitting width. The knitting ratio of the body part 2 and the leg part 3 to the buttock part 4 is a total of four garments and two garments. In the body molding, the molding position is changed between the front body and the back body so that the rear knit fabric 4B is longer.

  In the knitting of the next section S3, knitting is performed at the ratio of the third body to the first body, and at the same time, the heel part 4 is also formed to form the sharply curved parts 6F and 6B. The front body and the back body are molded at the same angle as viewed from the entire knitting width. Here, the reduction of the front knit fabric 4F is completed.

  In the knitting of the next section S4, knitting is performed at the ratio of the first garment to the first garment, and at the same time, the rear knitted fabric 4B is molded to form the stitch reducing portion 7B. Since the front side knit fabric 4F has been reduced in the section S3, the front body is provided with a dart part 9F corresponding to the rear side reduction part 7B. By forming darts for reducing the number of stitches in the middle of the knitted fabric of the front body, the number of stitches reduced in the back body matches the number of knitting widths in the front and back bodies. Here, the reduction of the stitches on the back knit fabric 4B is also completed.

  In the next section S5, the left and right body parts 2L and 2R are joined via the central extension parts 8F and 8B, and the body part 2 as a single tubular knitted fabric is formed as a whole.

  FIG. 2 shows the shape of the part that is knitted as the heel part 4 of FIG. 2A shows the shape of the front knit fabric 4F, and FIG. 2B shows the shape of the back knit fabric 4B. The heel part 4 to be actually knitted is the number of stitches in the set-up part. For example, when a 12 gauge gauge SWG-X type four-bed flat knitting machine, which is a product of Shima Seiki Seisakusho, is used, Can be formed.

  In the loose parts 5F and 5B corresponding to the section S2 in FIG. 1, the body 4th eye 2nd, that is, the left leg 3L, the buttocks 4 and the right leg 3R are knitted with a 4: 2: 4 course number. Repeat 8 times. In the gentle side portion 5F on the front side, the molding is performed so that the number of stitches is reduced by 2 every time one course is knitted. Therefore, after repeating 8 times, 2 × 8 = 16 stitches are reduced to 40−16 = 24 stitches. In the back gentle part 5B, the stitch width is not reduced and the knitting width of the 40th stitch is maintained.

  In the steep bends 6F and 6B corresponding to the section S3 in FIG. 1, the body 3rd eye 1st, that is, the left leg 3L, the buttocks 4 and the right leg 3R are knitted with the number of courses of 3: 1: 3. Repeat 11 times. Each steep curve portion 6F, 6B is molded so as to be reduced by 2 every time one course is knitted, so after repeating 11 times, it decreases by 2 × 11 = 22, and in the front-side sharp curve portion 6F, it is 24-22. = 2 and 40-22 = 18 in the rear sharp turn 6B.

  As for the collar part 4 corresponding to section S4 of FIG. 1, the front side becomes the extension part 8F of the width 2 and the rear side becomes the reduction part 7B. The knitting of the body 1st eye 1st eye, that is, the left leg 3L, the buttocks 4 and the right leg 3R with the number of courses of 1: 1: 1 is repeated 30 times. In the meantime, in the reduction part 7B, a total of 16 reductions are performed on each side, 8 eyes on both sides, and the remaining 2 eyes are transferred to the extension part 8B.

  The surface of the flange portion 4 is recessed in an arch shape by the loosely bent portions 5F, 5B and the sharply bent portions 6F, 6B, and the legs 3L, 3R can be smoothly joined. The arch shape is depressed because the ratio of the number of knitting courses of the knitted fabric of the heel part 4 and the number of knitting courses of the tubular knitted fabric of the leg portions 3L, 3R joined to the heel part 4 is more than 1: 1. This is because the flange 4 side is made smaller. Furthermore, the ratio of the number of courses for knitting the knitted fabrics 4F, 4B and the tubular knitted fabric is made different between the knitted fabrics 4F, 4B on the front side and the rear side. can do.

  In the joining process of the tubular knitted fabric of the legs 3L and 3R and the knitted fabric of the front and rear collars 4F and 4B, a course that does not join the front and rear collars 4F and 4B occurs on the leg 3L and 3R side. On the side of the heel 4F, 4B, the courses are joined to the legs 3L, 3R, respectively. The side portions joined on the front and rear flange portions 4F and 4B are stretched in the wale direction by the leg portions 3L and 3R, and are pulled so that the interiors of the front and rear flange portions 4F and 4B are curved to form curved surfaces. Can be formed. Since the ratio of the flange portion 4 is smaller in the sharply bent portions 6F and 6B than in the loosely bent portions 5F and 5B, a more remarkable depression is formed. Thus, the number of courses knitted on at least one of the front and rear side knitted fabrics 4F and 4B and the number of courses knitted on the tubular knitted fabric at the portion joined to the side knitted fabrics 4F and 4B. Since the ratio is set to be smaller on the side of the knitted fabrics 4F and 4B than 1: 1, the side joined to the tubular knitted fabric is pulled by the knitted fabrics 4F and 4B, and the knitted fabrics 4F and 4B The inside can be recessed in an arch shape, and the outline can be shaped along the human body.

  FIG. 3 shows the shape of the pants 1 manufactured according to FIGS. 3A shows a state seen from above, FIG. 3B shows a state seen from the front, and FIG. 3C shows a state seen from the back. FIG. 4 shows the shape of a tights 10 formed by extending the legs 3 of the pants 1 of FIG. 3 as seen from the side. The knitted fabrics 4F and 4B on the front side and the rear side of the heel portion 4 are knitted at the front and back boundaries of the loosely bent portions 5F and 5B. By forming the loosely curved portion 5B having a constant knitting width and the sharply curved portion 6B having a reduced knitting width on the rear side while forming the gently bending portion 5F and the sharply curved portion 6F in which the knitting width decreases on the front side. , The rear side can be greatly tightened. The number of eyes in this period is more three-dimensional because there are few heel parts 4 and many body parts. Further, the front body is molded while forming the rear-side reduction part 7B. The tubular knitted fabric such as the pants 1 is worn on the lower body of the human body, and the heel portion 4 is formed at the crotch portion between the two leg portions 3L and 3R of the tubular knitted fabric. The number of courses in the ground 4B can be increased to make room.

  FIG. 5 shows a basic thread winding for joining the knitted fabric while knitting the heel part 4 in the vicinity of the joint part of the legs 3L and 3R when knitting the pants 1 of FIG. In this figure and each figure related to the thread winding shown in FIG. 3 and subsequent figures, for convenience of explanation, the leg portion 3 and the heel portion 4 have the leg portions 3LF and 3RF and the heel portion 4F, which are knitted fabrics on the front side, at the front needle bed. Although the legs 3LB and 3RB and the heel part 4B, which are the knitted fabrics on the rear side, are shown in a state where they are knitted on the rear needle bed, the knitting of each knitted fabric is performed on the front and back needle beds as described above. Can be done using. In addition, the left and right sides of the needle bed are shown as seen from the front of the flat knitting machine, and the right side portion (leg portion 3R) of the knitted fabric knitted on the left side portion of the needle bed is locked and knitted on the right side portion of the needle bed. It is assumed that the left side portion (leg portion 3L) of the knitted fabric to be engaged is locked. The position where the yarn is fed in the description of the thread winding is shown with reference to the needle bed.

  First, in the first course A1, knitting yarn is fed in the direction from the outer end side to the inner end side of the knitting width in order to knit the knitted fabric of the rear side 3RB of the right leg 3R. In the next course A2, in order to knit the knitted fabric of the leg portion 3RB on the right rear side, the knitting yarn is fed from the inner end side to the outer end side of the knitting width. In the next course A3, the knitting yarn is turned from the outer end side to the inner end side of the knitting width in order to turn the knitting yarn around the front needle bed and knit the knitted fabric of the front side 3RF of the right leg 3R. Supply yarn. In the next course A4, to knit the knitted fabric of the leg portion 3RF on the right front side, the knitting yarn is fed from the inner end side to the outer end side of the knitting width. In the next course A5, the knitting yarn is turned to the rear needle bed, and the knitted fabric of the rear side 3RB of the right leg 3R, the rear collar 4B, and the left rear leg 3LB is continuously knitted. Therefore, the knitting yarn is fed in the direction from the left outer end side to the right outer end side of the knitting width.

  In the next course A6, the knitting yarn is turned from the outer end side to the inner end side of the knitting width in order to turn the knitting yarn around the front needle bed and knit the knitted fabric of the front side 3LF of the left leg 3L. Supply yarn. In the next course A7, to knit the knitted fabric of the leg portion 3LF on the left front side, the knitting yarn is fed from the inner end side to the outer end side of the knitting width. In the next course A8, the knitting yarn is turned to the rear needle bed, and the knitted fabric of the rear side 3LB of the left leg 3L is knitted in the direction from the outer end side to the inner end side of the knitting width. Supply the yarn. In the next course A9, to knit the knitted fabric of the leg portion 3LB on the left rear side, the knitting yarn is fed in the direction from the inner end side to the outer end side of the knitting width. In the next course A10, the knitting yarn is turned to the front needle bed, and the knitted fabric of the front side 3LF of the left leg 3L, the front heel part 4F, and the right front leg 3RF is continuously knitted. The knitting yarn is fed from the outer end side on the right side of the width to the outer end side on the left side.

  The thread winding described above may be performed so as to return to the start position with a single stroke. However, the ratio between the number of courses for knitting the heel part 4 and the number of courses for knitting the leg part 3 is 1: 3, so that the ratio of the number of courses of the buttock part 4 is lower than 1: 1. Thereby, as mentioned above, the knitted ridge part 4 can be made into the curved surface recessed in an arch shape.

  FIG. 6 shows a process of joining the left and right legs 3L and 3R through the collar 4 together with the thread winding shown in FIG. 5 and transferring and racking between the front and back needle beds. The front needle bed is shown with a downward sloping line, and the rear needle bed is shown with a right sloping line. While the leg portion 3 is knitted in three courses and the heel portion 4 is knitted in one course, the left and right leg portions 3L and 3R are molded so that two stitches in total are brought closer to the inside of the knitting width. The number of stitches shown as the leg portion 3 and the heel portion 4 is an example for convenience of explanation. Further, if the heel part 4 is knitted by, for example, 1 × 1 rib knitting, it can be easily extended.

  FIG. 7 shows the number of knitting courses of the knitted fabric of the heel part 4 and the tubular knitted fabric of the leg parts 3L and 3R joined to the heel part 4 in the section S2 when knitting the pants 1 of FIG. An example of a thread winding with a ratio of 1: 2 to the number of knitting courses is shown. The ratio of the number of courses knitting the left and right legs 3L, 3R and the heel part 4 is 4: 2: 4. This ratio can be realized by combining a one-stroke thread winding with a 3: 1: 3 course number as shown in FIG. 5 and a thread winding making a round with a 1: 1: 1 course number. That is, the courses B1 to B10 are performed in the same manner as the courses A1 to A10 in FIG. In the next course B11, the knitting yarn is turned to the rear needle bed, and the knitted fabric of the rear side 3RB of the right leg 3R, the rear collar 4B, and the rear side 3LB of the left leg 3L is continuously provided. In order to knit, the knitting yarn is fed from the left outer end side to the right outer end side of the knitting width. In the next course B12, the knitting yarn is turned to the front needle bed to continuously knit the knitted fabric of the front side 3LF of the left leg portion 3L, the front heel portion 4F, and the front side 3RF of the right leg portion 3R. The knitting yarn is fed in the direction from the outer end side on the right side of the knitting width to the outer end side on the left side.

  FIG. 8 shows a schematic shape of a setter 11 which is an example of a knitted product formed by a knitting method of a tubular knitted fabric having ridges as another embodiment of the present invention. The seta 11 is generally composed of a body 12 and a sleeve 13. The body 12 is knitted as one tubular knitted fabric. The sleeve portion 13 is formed in a cylindrical shape as the left and right sleeve portions 13L and 13R, joined to the body 12, and forms one cylindrical knitting. A collar portion 14 is provided at a portion where the sleeve portions 13L and 13R are joined to the body 12. When viewed from the left and right sleeve portions 13L and 13R, the sleeve portions 13L and 13R are joined to the body 12 with the left and right collar portions 14L and 14R interposed therebetween. As with the collar part 4 in FIG. 1, the collar part 14 reduces the number of courses so that the arch 15 is formed, and the sleeve parts 13L, 13R and the body part 12 are smoothly joined with curved surfaces. . On the front side and the rear side of the heel part 14, the front side knitted fabric 14F has a larger number of courses than the rear side knitted fabric 14B, so that the chest side can have a space. The adjustment of the number of eyes in the front and rear bodies may be performed by forming a dart.

  FIG. 9 shows an example of the shape of the collar portions 24 and 34 as still another embodiment of the present invention.
