Description

  The present invention relates to a slack lining and a method for producing the same.

  Conventionally, when wearing clothes such as slacks where the body shape from the abdomen to the waist and hips is relatively clear when worn, it is common for women to wear a girdle as a foundation to correct the body shape. Is. Recently, the slacks (trousers) designed and cut so that the hips rise as legs with beautiful legs and the legs look long are popular not only for women but also for men. However, although the means of wearing a girdle for body shape correction is effective, it is troublesome. Men do not have the habit of wearing girdle.

  In Utility Model Registration No. 3008616 (Patent Document 1), in Calson Pants which is a kind of slender slacks, a highly elastic power net with little elasticity is provided on the inner side from the front thigh to the waist. Stretched for abdominal correction, fastened at the waist periphery, outer side seams and inner side seams, and a stretch net with high elasticity and weak elasticity between the waist periphery and the hip line on the back body Tighten, fasten at the waist and outer side seams, and overlap the stretch net above the hip shape correction line above the hip line and the inseam thigh. A stretchable power net with little elasticity of the fabric is stretched and fastened at the lower end of the stretch net, the outer side seam and the inner side seam, and a belt-like 2 between the hip line and the hip shape correction line Straightening slacks for hip-up, characterized in that as the correction unit is disclosed.

  However, the slack disclosed in Patent Document 1 is a power net for abdominal correction during the manufacture of slacks, that is, when the outer side seam and the inner side seam are sewn together to sew the front body and the back body together. And stretch nets and power nets for hip correction must be sewn in place, which is very laborious. Moreover, power nets and stretch nets are stretchable, making it difficult to sew. In addition, for sewing knitted fabric materials that have elasticity and elasticity like power nets and stretch nets, special sewing dedicated to them. A machine is necessary, and it is a problem that a small-scale garment worker has such a large financial burden to always have such a special sewing machine.

  Furthermore, in the slacks of Patent Document 1, the hip correction power net and the stretch net are provided only on the back body of the slacks, and both ends are sewn on the outer side seams, so that the hips are strengthened. It is only holding down, and you can hardly expect the effect of lifting the hips up.

The present inventor previously proposed a slack lining that solves the above-mentioned problems in Japanese Patent No. 3509309 (Patent Document 2). The lining of the slacks in Patent Document 2 is not sewn to the slacks outer surface of each part like the one disclosed in Patent Document 1, but with a power net that is a knitted fabric material having elasticity, It was constructed as a semi-finished product with a fine underpants shape, and the waist part of the lining was sewn inside the waist part of the slacks outer material so that the lining was attached to the slacks outer material. Specifically, the lining of this slack is formed by contacting the crotch of the left cloth and right cloth made of power nets with the front center back part and the back center side part to form the crotch part. The bottom of the crotch was formed by contacting the edges of the crotch with the inner strips to form an underpants shape. In addition, the power net is cut into a tape with a predetermined width to form left and right reinforcing pieces, and these reinforcing pieces pass from the vicinity of the rear crotch part to the front center part of the waist part through the left and right side parts, respectively. And sewn to the right fabric. In this way, the reinforcing piece is sewn not only to the back body but also to the front center of the waist part through the side part, so the reinforcing piece acts to push up the wearer's hip part from below, and further to the front side Then, it acts to hold down the wearer's abdomen.
Utility Model Registration No. 3008616 Japanese Patent No. 3509309

  Although the lining of the slacks disclosed in Patent Document 2 has a large hip-up effect, there is a tendency to suppress the roundness of the hip by the power net. In addition, although the body is thick, the size is set to be thin for body shape correction, so even if the power net is stretchable, it cannot sufficiently cope with the thickness of the body. In other words, when wearing slacks, it is desirable that the crotch of the lining presses the abdomen of the wearer and the tightness is tightly attached to the body to a certain extent for hip-up. The wearer's crotch and legs were also in a tightened state, causing a problem of being cramped and not wearing well.

  The present invention solves the problem of the lining of Patent Document 2 as described above, does not tighten the crotch and legs of the wearer, can provide a more comfortable wearing feeling, and does not crush the roundness of the hip as much as possible. The purpose is to provide a slack lining with an up effect.

  In addition, since the lining of the present invention is made of a stretchable fabric, it is difficult to sew together if a curve with a small curvature is drawn, such as a crotch curve used for a pattern of a normal slack's front fabric. Therefore, the present invention uses a slack lining that is easy to sew by designing parts to correspond to the wearer's crotch thickness and leg thickness without using a curve with a small curvature. The purpose is to provide.

  Further, as the number of parts constituting the lining increases, it takes time and effort to sew. Therefore, the present invention is intended to provide a slack lining that is easy to wear without increasing the number of parts as much as possible.

  It is another object of the present invention to provide a lining that can be more easily performed than before by using the lining of the present invention in connection with the fastening of slacks.

  The object of the present invention is to provide a method for producing the backing of the slacks of the present invention as described above.

  The present invention is an underpants-shaped slack lining having a crotch upper part and a leg part, the lining comprising a left crotch part and a left leg part that is continuous with the left crotch part, a right crotch part And the right side cloth that is continuous to the right side leg part, the auxiliary cloth that constitutes a part of the leg part, and the left and right hip-up reinforcing cloths, the left side cloth, the right side cloth, the auxiliary cloth, and the reinforcing cloth. Is a knitted fabric material having elasticity, and the crotch part of the left and right fabrics is stitched together at the edges on the rear center side, and on the front center side, a slide fastener is inserted from the upper end of the waist part to the left and right fabrics. A front center side of the crotch portion that is attached to the front center side edge of the cloth, and that the front center edge of the left side cloth and the right side cloth can be opened and closed by the slide fastener, and is below the bottom fastener of the slide fastener. The edges of each other stitch together The reinforcement cloth for hip-up is sewn to the left-side cloth and the right-side cloth respectively from the vicinity of the rear crotch part to the front center part of the waist part through the left and right side parts. The cloth has a substantially rectangular shape, the length of the long side is about twice the length of the leg of the left cloth or the right cloth, and the edge of one long side of the auxiliary cloth is the left cloth and The edge of the other long side of the auxiliary cloth is stitched to the rear edge of the left cloth and the leg of the right cloth, and the hip up The hips of the left and right fabrics above the reinforcing fabric are stretched to form a bulge, and the lining further includes an elastic tape, and the elastic tape is sewed in the stretched state. Sewing on at least the lower part of the rear center edge Attached to the lower portion of the rear center edge, and the lining is attached by sewing its waist portion to the inside of the waist portion of the slacks outer surface, and the front opening edge of the slack surface material Is achieved by a slack lining characterized by being sewn to the slide fastener of the lining.

  When the elastic knitted fabric material is a power net, both the left and right fabrics are set so that the direction in which the left and right fabrics are stretched is the lateral direction of the underpants-shaped lining, and the auxiliary fabric has a large stretch. It is preferable that the direction is set to the direction of the short side, and the left and right reinforcing cloths are set so that the stretchable direction is the vertical direction of the underpants-shaped lining.

  When attaching the lining of the present invention to the slacks outer material, the hip-up reinforcing cloth and the elastic tape may face the slacks outer material, or conversely, do not touch the slacks outer material and be positioned inside the lining material. Also good. In particular, when the crotch portion of the slacks is thin and has no room for clearance, it is preferable that the hip-up reinforcing cloth and the elastic tape are located inside the lining so that the shape of the lining does not affect the appearance.

  Further, according to the present invention, the knitted fabric material having elasticity is cut so as to form an underpants-shaped slack lining having a crotch part and a leg part, and a left crotch part and a left side continuous with the crotch part Left side cloth constituting the leg part, right side cloth part comprising the right crotch part and the right leg part continuous thereto, a substantially rectangular auxiliary cloth constituting part of the leg part, and left and right hip-ups A step of forming a reinforcing fabric for sewing, a step of sewing the reinforcing fabric to each of the left side fabric and the right side fabric from the vicinity of the rear crotch portion through the left and right side portions to the front center portion of the waist portion, the left side A step of stitching together the edges of the back center side of the crotch part of the cloth and the right side cloth, pressing the convex mold on the hip part of the left side cloth and the right side cloth above the hip-up reinforcing cloth, and performing heat treatment, Cloth on the hip area A step of forming a bulge, a step of stitching together a lower portion of the front center side edge of the crotch part of the left side fabric and the right side fabric, an edge portion of one long side of the auxiliary fabric on the left side fabric and Stitching to the front edge of the leg of the right fabric, stitching the edge of the other long side of the auxiliary fabric to the rear edge of the left fabric and the leg of the right fabric, the center edge after the stitching A slack comprising: a step of sewing an elastic tape to a lower portion of the portion in a stretched state; and a step of attaching a slide fastener to an upper portion of the front center side edge of the crotch portion of the left and right fabrics. The object is achieved by a method of manufacturing a lining.

  Furthermore, the present invention is such that the waist portion of the lining of the slacks manufactured by the above method is sewn to the inside of the waist portion of the slacks outer material, the lining material is attached to the slacks outer material, and the edge of the front opening in the slacks outer material is The object is achieved by a method of attaching a slack lining, characterized by being sewn to a slide fastener.

  The lining of the slacks of the present invention is an underpants-shaped slack lining having a crotch and legs, and is made of a stretch knitted fabric material, so this lining is inside the waist of the slacks outer material When sewn and attached, the lining fits elastically to the wearer's waist, hips, abdomen, thighs, etc. in slacks wearing state, and body shape correction can be performed.

  According to the present invention, an auxiliary cloth made of a stretch knitted fabric material constitutes a part of the leg, the auxiliary cloth is substantially rectangular, and the length of the long side is the left side cloth or Twice the length of the leg of the right fabric, the edge of one long side of the auxiliary fabric is stitched to the front edge of the left fabric and the leg of the right fabric, and the length of the other long side of the auxiliary fabric Edges are stitched to the rear edge of the left and right leg legs. By sewing the auxiliary cloth on the left and right cloths in this way, the left cloth and the right cloth are stitched together at the front center and the rear center as in Patent Document 2, although the crotch is perfect. Compared to the case, the crotch dimension (the length from the center of the front of the waistline to the center of the back of the waistline) is increased by the length of the short side of the auxiliary cloth, and the length of the auxiliary cloth is short at the crotch. Allow plenty of space for the length of the side. At the same time, as in Patent Document 2, the circumference of the leg portion is increased by the length of the short side of the auxiliary fabric as compared with the case where the crotch edges of the left and right fabrics are sewn together. In this way, by using a substantially rectangular auxiliary cloth, the crotch part fits in the same way as before, but the lining does not bite into the wearer's crotch, and the legs are overtightened The feeling of wearing is very good.

  In addition, since the auxiliary cloth is rectangular or substantially rectangular, the left and right cloths are also stitched together in a straight line, and can be easily and neatly sewn with a sewing machine without requiring skill.

  Furthermore, by using an auxiliary cloth, it is not necessary to use a curve with a small curvature at the crotch part, so that sewing is easy.

  Further, according to the present invention, the number of parts constituting the underpants-shaped lining body is only one auxiliary cloth, and since the shape is substantially rectangular, even a stretchable fabric can be easily cut. Moreover, since the auxiliary cloth is sewn in a straight line, it is easy to sew and does not require labor.

  According to the present invention, since the cloth of the hip part in the left cloth and the right cloth above the hip-up reinforcing cloth is stretched to form a bulge, the roundness of the hip of the slacks wearer is not crushed and is beautiful. It can be in a state of hip up.

  In addition, the knitted fabric material with elasticity is a power net, and the left and right fabrics are set so that the direction of great elasticity is the lateral direction of the underpants shape lining, and the auxiliary fabric has the short side of the direction of great elasticity. The left and right reinforcing fabrics are set in the longitudinal direction of the underpants-shaped lining. The power net is a warp knitted fabric, and has a property that the stretchability is large in the longitudinal direction of the fabric, but the stretchability is small in the width direction. Therefore, when each part is cut so as to be in the stretch direction as described above, the left and right cloths extend in the wearer's waist direction and thigh circumferential direction, and the auxiliary cloth also extends in the thigh circumferential direction. Since it stretches, it is easy to wear and gives a moderate fit to the thigh, but does not give a tight feeling. On the other hand, the reinforcing fabric is sewn on the left fabric and the right fabric, and is difficult to stretch in the lateral direction, so it has a great effect of supporting the lower part of the hip and can be pressed firmly in the abdomen. .

  In the present invention, a fastener is attached to the lining, and this is also used as a common fastener for the slack surface. In addition, according to the present invention, the zipper is attached to the underpants-shaped lining so that it can be freely opened and closed, so that the hip-up effect and the abdomen tightening effect similar to those of the conventional girdle can be obtained, but compared with the conventional girdle. Therefore, it is very easy to attach and detach. Therefore, when attaching and detaching the slacks to which the lining of the present invention is attached, the slacks not using the lining of the present invention can be easily put on and taken off.

  According to the method of the present invention, the hip-up effect is large, the abdomen is tightened, the lining does not bite into the wearer's crotch, and the legs are not tightened too much, so the wearing feeling is very good. An underpants-shaped lining can be easily manufactured.

  According to the method of the present invention, the convex part is pressed against the hip part of the left and right cloths above the hip-up reinforcing cloth to perform heat treatment (so-called molding process), and the cloth at the hip part is formed. Since it stretches to form a bulge, it can create a beautiful hip line without crushing the wearer's hip.

  Hereinafter, the present invention will be described in detail based on the embodiments shown in the drawings. FIG. 1A is a front view of the slack lining of the present invention in a flat state, and FIG. 1B is a rear view thereof. FIG. 2 is a plan view showing parts constituting the lining main body, and FIG. 3 is a plan view showing an embodiment of mold insertion when cutting the parts.

  As shown in FIG. 1, the lining of the slacks of the present invention has an underpants shape having a crotch A and a leg B, and a lining body 1 made of a stretchable knitted fabric material and a slide fastener attached thereto. 2 and elastic tape 3.

  As shown in FIGS. 1 and 2, the lining main body 1 includes a left cloth 11 comprising a left crotch A and a left leg B continuous thereto, a right crotch A and a right leg continuous thereto. It consists of a right-hand cloth 12 constituting part B, an auxiliary cloth 13 constituting a part of leg part B, and left and right hip-up reinforcing cloths 14.

  As shown in FIG. 1 (a), the crotch A of the left cloth 11 and the right cloth 12 has the edges 11a and 12a (see FIG. 2) of the lower part of the crotch A sewn together at the front center 1a. The slide fastener 2 is attached to the edge of the left cloth 11 and the right cloth 12 from the upper end of the waist 1c (the waistline portion having a width of 1 to 3 cm from the upper end of the lining main body 1). The upper end of the slide fastener 2 to the lower stop 22 is attached to the fastener attachment edges 11c and 12c (see FIG. 2) of the left cloth 11 and the right cloth 12. It is attached to the edges 11a, 12a of the right fabric 12. The front center 1a of the lining main body 1 can be opened and closed by moving the slider 21 of the slide fastener 2 up and down.

  Further, as shown in FIG. 1B, the crotch part A of the rear body of the left cloth 11 and the right cloth 12 has the edges 11b and 12b (see FIG. 2) sewn together at the rear center 1b. The elastic tape 3 is sewn to the lower part of the stitched edges 11b and 12b in a stretched state. Since the elastic tape contracts after being sewn, gathers 1d are formed on the left cloth 11 and the right cloth 12 below the rear center 1b.

  The hip-up reinforcing cloth 14 is sewn to the left-side cloth 11 and the right-side cloth 12 so as to pass from the vicinity of the rear crotch part through the left and right side parts to the front center part of the waist part 1c.

  Further, as shown in FIG. 1 (b), in the rear body, the hips 1e of the left cloth 11 and the right cloth 12 above the hip-up reinforcing cloth 14 are stretched to form a bulge (the present invention). Since the bulge is formed and wrinkles are formed in the portion when the lining of the material is placed flat, the wrinkles are schematically represented by lines in FIG. 1 (b). Thus, by forming the bulge in the hip part 1e and forming the gather 1d, a space corresponding to the roundness of the wearer's hip is applied to the lining of the present invention so that the roundness of the hip is not crushed.

  Further, the auxiliary cloth 13 has a substantially rectangular shape as shown in FIG. 2, and as shown in FIG. 1A, the edge 13 a of one long side of the auxiliary cloth 13 is a leg portion of the left cloth 11 and the right cloth 12. 1B, the other long side edge 13b of the auxiliary cloth 13 is located on the rear side of the leg B of the left cloth 11 and the right cloth 12, as shown in FIG. It is sewn to the edge parts 11e and 12e. Since the auxiliary cloth 13 is attached to the left cloth 11 and the right cloth 12 in this way, there is room for the crotch thickness and leg thickness of the body by the length of the short side of the auxiliary cloth 13. Let

  The length of the long side of the auxiliary cloth 13 is about twice the length of the leg B of the left cloth 11 or the right cloth 12. That is, since the long sides 13a and 13b of the auxiliary cloth 13 are sewn together with the edges of the leg portions B of the left cloth 11 and the right cloth 12, the left cloth 11, the right cloth 12, and the auxiliary cloth 13 are not stretchable at all. Then, the length of one long side 13a is the length obtained by subtracting the seam allowance of the two edges 11a and 12a from the total length of the front edge 11d and the length of the edge 12d in the leg B. The length of the other long side 13b is the length obtained by subtracting the seam allowance of the two edges 11b and 12b from the total length of the rear edge 11e and the edge 12e in the leg B. It becomes. However, since the left cloth 11, the right cloth 12, and the auxiliary cloth 13 have elasticity, it is not necessary to have a strict length.

  The lower end of the front center 1a and the lower end of the rear center 1b are crotch portions, and when the lining of the present invention is laid flat, the auxiliary cloth 13 in the crotch is left over, resulting in three-dimensional unevenness. In FIGS. 1 (a) and 1 (b), the auxiliary cloth 13 is schematically shown without drawing such unevenness.

  As the knitted fabric material having elasticity that constitutes the lining main body 1, a power net (a plain power net, a pattern power net, a satin-like power net, a triconette, or the like), a two-weight ricot, or the like can be used. In particular, the power net is a warp knitted fabric having directionality in stretchability, and is characterized in that the stretchability is large in the longitudinal direction of the warp knitted fabric and the stretchability in the width direction is small.

  For this reason, when using a power net, both the left cloth 11 and the right cloth 12 have the direction in which the stretchability is large as the lateral direction (the waistline direction) of the underpants-shaped lining, and the auxiliary cloth 13 has the short stretch direction. It is preferable that the left and right hip-up reinforcing fabrics 14 have the direction of the sides, and the direction in which the stretchability is large is the vertical direction of the underpants-shaped lining (the vertical direction when worn). In this case, the stretchability is large in the waist direction of the wearer, the thickness direction of the body (crotch), and the circumferential direction of the thigh, and an appropriate fit is provided, but a tight feeling is not given. On the other hand, the reinforcement cloth 14 for hip-up does not extend in the lateral direction at the lower part of the abdomen or the hip, firmly presses the abdomen, and firmly supports the lower part of the hip.

  In the embodiment shown in FIG. 1, nothing is provided on the legs of the underpants-shaped lining of the present invention, but a lace may be sewn on the lower ends of the left and right legs B. Alternatively, a decorative stitch may be hung on the lower end of the leg B.

  The underpants-shaped lining of the present invention is attached to a slacks outer surface (those in the shape of slacks). In that case, the waist portion 1c of the lining can be easily sewn to the inside of the waist portion of the slack surface with a main sewing (straight stitch) sewing machine. The front opening edge of the slacks outer material is sewn to the tape part 23 of the slide fastener 2 of the lining. Thus, the slide fastener 2 attached to the lining is used as a fastener for slacks that are products. Therefore, when wearing slacks that are products, the slider 21 of the fastener 2 is lowered to open the front, but at the same time, the front of the underpants-shaped lining of the present invention can also be opened, so it is easy to wear slacks. When the slider 21 is raised and the fastener 2 is closed, the front opening of the slacks is closed, and at the same time, the abdomen tightening effect and hip-up effect are obtained by the lining of the present invention.

  Thus, since the lining of the present invention only sews the waist portion 1c and the tape portion 23 of the slide fastener 2 to the outer surface of the slacks, the lining of the present invention is thin so as to fit the body, Even slacks with a loose shape do not pull on the surface of the slacks.

  Further, in the case of slacks having a loose shape, the seam allowance portions obtained by sewing the left cloth 11, the right cloth 12, and the auxiliary cloth 13 so that the hip-up reinforcing cloth 14 and the elastic tape 13 face the slack outer surface, respectively. The lining is preferably attached to the slack surface so that it faces the slack surface. In this way, there is no ledge on the inside of the slacks that are the product (that is, the inside of the lining), and the appearance is also beautiful.

  Conversely, in the case of slacks that fit the wearer's hips, the hip-up reinforcing fabric 14 and the elastic tape 13 are located on the inner side of the lining so that they do not touch the slacks outer material. It is preferable to attach a lining. If it does in this way, the reinforcement cloth 14, the elastic tape 13, and the protrusion by a seam allowance will not affect the outer surface of a slacks.

  Below, the manufacturing method of the backing of the slacks of this invention is demonstrated.

  FIG. 3 shows an example of a case (pattern layout) of each part constituting the lining main body 1 shown in FIG. 2 when a power net is used as a knitted fabric material having elasticity. In FIG. 3, the arrow indicates the direction in which the stretchability is large, and coincides with the length direction of the warp knitted fabric. That is, the left side cloth 11 constituting the left crotch part A and the left leg part B continuous thereto and the right side cloth 12 constituting the right crotch part A and the right leg part B continuous thereto are both expanded and contracted. The auxiliary cloth 13 having a substantially rectangular shape that constitutes a part of the leg portion B has a direction in which the stretchability is large and the direction of the short side. The left and right hip-up reinforcing fabrics 14 are both molded in such a manner that the direction in which the stretchability is large becomes the vertical direction of the underpants-shaped lining, and these are cut to create each part.

  Next, the reinforcing cloth 14 is applied to each of the left side cloth 11 and the right side cloth 12 that has been created, from the vicinity of the rear crotch part, through the left and right side parts (indicated by reference numeral 1f in FIG. 1), to the front center part of the waist part 1c. Sewing everywhere. FIG. 4 is a plan view showing a state in which the reinforcing cloth 14 is sewn to the right cloth 12. When sewing, it is preferable to sew with a zigzag sewing machine, for example, with 4-point zigzag stitching.

  As shown in FIG. 5, the left-side cloth 11 and the right-side cloth 12 sewn with the reinforcing cloth 14 are sewn together at the rear center side edges 11b and 12b of the crotch A with, for example, a main sewing machine.

  A convex mold is pressed against the place of the hip part 1e in the left cloth 11 and the right cloth 12 above the hip-up reinforcing cloth 14, and heat treatment is performed to stretch the cloth at the hip part 1e to form a bulge. In this case, as shown in FIG. 5, heat treatment is performed by a mold processing machine in a state where the sewn left cloth 11 and right cloth 12 are spread. The molding machine used in the present invention is not particularly limited. For example, as schematically shown in FIG. 6, a cloth placing table 51 having holes or recesses 52, a square cloth presser frame 53 that can move up and down, and a convex type 54 and a support 55 that can move up and down. The convex mold 54 is heated and is inserted into the hole or the concave portion 52 when lowered. When performing molding with such an apparatus, first, the left cloth 11 and the right cloth 12 sewn on the cloth placing table 51 are spread so that the position of the hip portion 1e coincides with the hole 52, that is, 2 The fabrics 11 and 12 are placed so that the rear center 1b is located between the two holes 52, and the hip-up reinforcing cloth 14 is located around the hole 52 without closing the hole 52. Then, the cloth presser frame 53 is lowered to press around the left cloth 11 and the right cloth 12 so that the cloths 11 and 12 do not move. Next, for example, the support body 55 having the convex mold 54 heated to 180 ° C. ± 10 ° C. is lowered. The convex mold 54 descends into the hole 52 while stretching the cloth at the hip portion 1e of the left cloth 11 and the right cloth 12. After maintaining this state for about 16 seconds, the convex mold 54 is raised. Thereafter, the cloth presser frame 53 is raised and the cloths 11 and 12 are removed from the cloth placing table 51. In this way, the fabric at the location of the hip portion 1e is stretched and heat-set in a state where a bulge is formed. It is convenient to perform the molding process with the left and right cloths 11 and 12 sewn together in such a manner that the work is easy to perform and it is possible to confirm the location where the bulge is to be formed.

  Next, the lower portions 11a and 12a of the edge of the crotch A of the left cloth 11 and the right cloth 12 on the side of the front center 15a are sewn together by a main sewing machine. Thereby, the lower part of crotch part A becomes cylindrical.

  Then, the edge 13a of one long side of the auxiliary | assistant cloth 13 is continuously sewn on the front edge parts 11d and 12d of the leg part B of the left-side cloth 11 and the right-side cloth 12 by a main sewing machine. That is, half of the length of one long side of the auxiliary cloth 13 is sewn to the edge 11 d of the left cloth 11, and the other half is sewn to the edge 12 d of the right cloth 12. Further, the edge 13b of the other long side of the auxiliary cloth is continuously sewn to the rear edges 11e and 12e of the leg B of the left cloth 11 and the right cloth 12 in the same manner by a main sewing machine. Thereby, the cylindrical left and right leg portions B are formed.

  As described above, since the leg B is formed using the auxiliary cloth 13 as well as the legs of the left cloth 11 and the right cloth 12, the edges 11d, 12d, 11e of the legs of the left cloth 11 and the right cloth 12 are used. , 12e hardly use a curve with a small curvature. For this reason, the auxiliary cloth 13 and the left cloth 11 and the auxiliary cloth 13 and the right cloth 12 can be easily sewn.

  Preferably, the seam allowance of the rear center edges 11b and 12b sewn as described above, the seam allowance of the front center edges 11a and 12a sewn together, and the edges 11d, 12d, 11e and 12e of the leg B sewn with the auxiliary cloth 13 are preferable. , 13a and 13b are respectively divided, and a zigzag stitching machine is hung on the divided sewing allowance, and the seam allowance is divided and fixed.
