Description

[Technical field]

[0001] The present invention relates to clothing. [Background technology]

[0002] It is generally known that when a joint such as a hip joint or a knee joint is moved, for example, by bending, the skin of the buttocks or knees stretches more than before bending. Pants as clothing have a pair of left and right tubular parts that cover the legs of a wearer. When bending the buttocks or knees, the buttocks or knees of the wearer stretch while moving through the gap between the inner space of the tubular parts and the buttocks or knees so as to approach the inner surface of the tubular parts.

[0003] At this time, depending on the margin of the gap between the inner space of the tube part and the buttocks or knees, when the buttocks or knees come into contact with the inner surface of the tube part and the buttocks or knees are further bent from the point of contact, tension acts on the contact points between the knees and buttocks of the fabric of the tube part, causing tension in the buttocks or knees, preventing the buttocks or knees from bending due to the pants, or causing discomfort.

[0004] Patent Document 1 discloses pants made of a stretchable fabric that can follow the bending of the hips and knees.

[0005] Patent Document 2 discloses pants that are made of a low-stretch fabric and have a slit on the outside of the gluteal crease that slopes backward from the side line, and a slit on the front of the knee area that runs from the front of the thigh to the inside or outside of the knee, to reduce tightness that occurs when the leg is raised outward.

[0006] [Patent Document 1] Patent Publication No. 2012-167379 [Patent Document 2] International Publication No. 2014-125609 Summary of the Invention [Problem to be solved by the invention]

[0007] The pants in Patent Document 1 have side seams that sew the front and back body pieces together on the outside in the width direction, and the side seams have lower elasticity than other parts, which can hinder movements such as flexion of the buttocks and knees.

[0008] The pants of Patent Document 2 have slits and / or a stretchable fabric that covers the slits in addition to the slits, which tends to reduce the freedom of design of the garment.

[0009] The present invention provides clothing that does not impede movement of the wearer's joints without compromising design freedom when the wearer moves their joints. [Means for solving the problem]

[0010] One aspect of the present invention provides clothing which covers the wearer's body and has at least a portion thereof provided with a slip-promoting portion which, when the wearer's joints are moved, promotes slipping of the clothing in a direction which makes it easier to move the joints, or which inhibits the clothing from being hindered from slipping in a direction which makes it easier to move the joints.

[0011] According to the present invention, a garment can be provided that, by virtue of a slip-promoting portion provided on at least a portion of the garment, does not slip relative to the wearer's joints when the wearer moves the joints, thereby preventing the wearer from impeding the movement of the joints. For example, when a garment having a slip-promoting portion is applied to pants, if the buttocks or knees bent during exercise come into contact with the inner surface of the tubular portion of the pants and are then bent further, the slip-promoting portion causes the tubular portion to slip relative to the knees or buttocks. This makes it possible to suppress tension from acting between the contact points, as would occur if the tubular portion were fixed without slipping. Effect of the Invention

[0012] According to the present invention, it is possible to provide clothing that does not impede movement of the wearer's joints when the wearer moves the joints, without compromising design freedom. [Brief description of the drawings]

[0014] This embodiment relates to pants 1 as clothing. The pants 1 are provided with a slippage promoting portion at least in a part thereof, and the slippage promoting portion causes the pants 1 to slip relative to the wearer's joints when the wearer moves the joints, thereby obtaining an effect of not impeding the movement of the wearer's joints. The pants 1 according to one embodiment of the present invention will be described below with reference to the drawings.

[0015] 1 shows a front view of a bottom garment (hereinafter also referred to as "pants") 1 as a garment according to one embodiment of the present invention, laid flat. Hereinafter, the top and bottom, left and right, and front and back of the pants 1 will be defined based on a state in which a wearer wearing the pants 1 is standing upright. In addition, the direction from the outer surface to the inner surface in the thickness direction of the fabric is defined as the inside, and the opposite is defined as the outside, and the direction toward the outside in the width direction is defined as the outside, and the direction toward the center is defined as the inside.

[0016] 1 and 2, pants 1 of this embodiment are long trousers that extend from the waist to the ankles of a wearer. The pants 1 have a pants body 10 that is placed from the buttocks to the ankles, and a waist belt part 20 that is placed around the waist.

[0017] The pants body 10 has a cylindrical crotch portion 10a that covers the waist and buttocks, and a cylindrical crotch portion 10b that is arranged below the crotch portion 10a and splits into two to cover the left and right leg portions.

[0018] 1 and 2, the pants body 10 has a front body fabric 11 that covers the wearer's abdomen side and a back body fabric 12 that covers the wearer's buttocks side. The front body fabric 11 has a left front body fabric 11a located on the wearer's left side and a right front body fabric 11b located on the wearer's right side. The back body fabric 12 has a left back body fabric 12a located on the wearer's left side and a right back body fabric 12b located on the wearer's right side.

[0019] The pants body 10 has a front body fabric 11 and a back body fabric 12 sewn together on the widthwise outer side and the widthwise inner side to form a crotch tube portion 10a and a pair of left and right crotch tube portions 10b.

[0020] The pants body 10 has a front rise seam 24, a back rise seam 25, a pair of left and right side seams 26, and a pair of left and right inner thigh seams 27. The front rise seam 24 and the back rise seam 25 are formed on the rise tube portion 10a. Each rise seam 24, 25 extends vertically from the crotch portion 23 located in the crotch of the wearer to the waist portion 21.

[0021] The front rise seam 24 is formed by sewing together the left front body fabric 11a and the right front body fabric 11b on the widthwise inner side. In this embodiment, an engagement portion (fastener portion) is provided between the left front body fabric 11a and the right front body fabric 11b to form the front rise seam 24, but an engagement member does not have to be provided. The back rise seam 25 is formed by sewing together the widthwise inner end of the left back body fabric 12a and the widthwise inner end of the right back body fabric 12b.

[0022] 3 is a side view of the pants 1, as seen from the side of the left side seam 26, in which the side fold lines 71 formed on the outer side in the width direction overlap with the inner thigh fold lines 72 formed on the inner side in the width direction when the pants 1 are laid flat as shown in FIG. 1. In the present embodiment, the flat lay state refers to a state in which the front rise seam 24 and the back rise seam 25 of the pants 1 are aligned in the width direction, and the rise tube portion 10a and the crotch tube portion 10b are stretched out without wrinkles. The pants 1 in the side view shown in FIG. 3 may be arranged such that the front-to-rear positions of the pair of side seam lines 26 are aligned in the waist portion 21, the front-to-rear positions of the pair of inner thigh lines 27 are aligned in the crotch portion 23, and the front-to-rear positions of the pair of side seam lines 26 and the pair of inner thigh seam lines 27 are aligned in the hem portion 22.

[0023] As shown in Fig. 3, a pair of side seam lines 26 are formed from the crotch tube portion 10a to the crotch tube portion 10b. Each side seam line 26 extends vertically from the waist portion 21 to each hem portion 22. Each side seam line 26 is formed by sewing together the widthwise outer end of the front body fabric 11 and the widthwise outer end of the back body fabric 12. Since each side seam line 26 has the same configuration on the left and right, only the left side seam line 26 will be described in this embodiment.

[0024] As shown in Fig. 3, each side seam line 26 generally slopes backward as it extends downward. Each side seam line 26 intersects with a side fold line 71 at the middle in the up-down direction. As shown in Fig. 1, each side fold line 71 is a portion that forms the outer edge of the pants 1 when laid flat, and is symmetrical.

[0025] The side seam 26 has a first side seam 26a located on the rise tube portion 10a, a second side seam 26b located on the upper part of the crotch tube portion 10b, and a third side seam 26c located on the lower part of the crotch tube portion 10b. The first side seam 26a extends from the waist portion 21 to the jumper line 61. The second side seam 26b extends from the jumper line 61 to the knee line 62. The third side seam 26c extends from the knee line 62 to the hem portion 22.

[0026] In this embodiment, the jumper line 61 extends widthwise outward through point P where the front rise seam line 24, the back rise seam line 25, and the pair of left and right inner thigh seam lines 27 cross in the crotch portion 23, as shown by the two-dot chain line in FIG. 1, and is a straight line that is approximately perpendicular to the side fold line 71.

[0027] In this embodiment, the knee line 62 is a straight line perpendicular to the armpit fold line 71, 6 cm above the position where the inseam is vertically bisected, as shown by a two-dot chain line in FIG. 1. The knee line 62 is located near the knee of the wearer, and in this embodiment, it is located at a position corresponding to the apex of the knee when a specific mannequin (MD-20A (men's M size) manufactured by Nanasai Co., Ltd.) is dressed. In this embodiment, the distance between the knee line 62 and the position where the inseam is vertically bisected is set to 6 cm when the inseam Z (for example, 73.5 cm) is used as a reference, and the inseam at this time is set as the reference inseam. For example, when the inseam is set to Z1, which is longer than the reference inseam, in order to set a different size, the distance is set to a value obtained by adding half the difference from the reference inseam ((Z1-Z) / 2) to 6 cm. On the other hand, when the inseam length is set to Z2, which is shorter than the standard inseam length, the distance is set to a value obtained by subtracting half the difference from the standard inseam length ((Z-Z2) / 2) from 6 cm.

[0028] 3, the first side seam 26a is located forward of the side fold line 71. The first side seam 26a extends approximately parallel to the side fold line 71 between the waist portion 21 and the crossover line 61. The distance D1 between the first side seam 26a and the side fold line 71 on the crossover line 61 is set to, for example, 1.5 cm.

[0029] The second side seam 26b continues downward from the lower end of the first side seam 26a. The second side seam 26b is inclined downward and backward. The side inclination angle α1 of the second side seam 26b with respect to the side fold line 71 is preferably set to 5 degrees or more and 15 degrees or less. In this embodiment, the side inclination angle α1 is set to 12 degrees.

[0030] The second side seam 26b intersects with the side fold line 71 at the middle in the vertical direction. The intersection P1 between the second side seam 26b and the side fold line 71 is preferably located 50% to 57% above the second intersection P3 with respect to the distance L1 between the first intersection P2 where the jumper line 61 intersects with the side fold line 71 and the second intersection P3 where the knee line 62 intersects with the side fold line 71. In this embodiment, the intersection P1 is located 50% above the second intersection P3 with respect to the distance L1. If the intersection P1 is located above the second intersection P3 by less than 50% with respect to the distance L1, the distance D2 between the wearer's knee and the second side seam 26b is shortened if the inclination angle α1 is constant, and the second side seam 2b is likely to come into contact with the knee during bending and stretching, and the pants 1 is not likely to slip. If the inclination angle α1 is increased, the inclination of the second side seam 26b becomes large, which may reduce the design freedom. If the intersection point P1 is located above the second intersection point P3 by more than 57% with respect to the distance L1, the second side seam 26b tends to be located behind the side fold line 71, which tends to reduce the roominess of the back body fabric 12 on the thigh and buttocks sides, where room is needed when bending and stretching.

[0031] FIG. 4 is a schematic diagram showing a state in which the crotch tube portion 10b is arranged in a cylindrical shape in a cross section taken along line IV-IV in FIG. 3. As shown in FIG. 3 and FIG. 4, the distance D2 between the third intersection point P4 of the second side seam line 26b and the knee line 62 and the second intersection point P3 is preferably set to a length of 3.57% to 17.9% of the circumference D3 of the crotch tube portion 10b at the knee line 62. In this embodiment, the distance D2 is set to, for example, 4.76% of the circumference D3. In this embodiment, since the circumference D3 is set to 42 cm, the distance D2 may be set to 1.5 cm to 7.5 cm, for example, 2 cm. The distance D2 may have a manufacturing error of 0.5 cm, but even if such a manufacturing error is present, the effect of not hindering the movement of the wearer's joints can be exhibited. If the separation distance D2 exceeds 7.5 cm, the side seam line 26 will be located on the rear side, which will tend to result in slack in the front body fabric 11 in front of the side fold line 71, and in a non-aerial position (standing position), the front body fabric 11 will tend to sag and wrinkle, which may result in an unattractive appearance.

[0032] 3, the third side seam 26c is located behind the side fold line 71. The third side seam 26c is continuous with the second side seam 26b and is slightly inclined backward and downward. The third side seam 26c may be generally parallel to the side fold line 71 and extend in the up-down direction.

[0033] 5 is a schematic diagram showing a cross section along line VV in FIG. 3, in which the crotch tube portion 10b is arranged in a cylindrical shape. As shown in FIG. 3 and FIG. 5, the distance D4 between the fourth intersection P5 where the third side seam line 26c and the hem portion 22 intersect and the fifth intersection P6 where the side fold line 71 and the hem portion 22 intersect is preferably set to a length of 2.7% to 16.2% of the circumference D5 of the crotch tube portion 10b at the hem portion 22. In this embodiment, the distance D4 is set to a length of 8.1% of the circumference D5. In this embodiment, since the circumference D5 is set to 37 cm, the distance D4 may be set to a length of 1 cm to 6 cm, for example, 3 cm.

[0034] As shown in Fig. 1, a pair of right and left inner thigh seam lines 27 are formed on the crotch tube portion 10b. Each inner thigh seam line 27 extends in the up-down direction from the crotch portion 23 to each hem portion 22. Each inner thigh seam line 27 is formed by sewing together the widthwise inner end of the front body fabric 11 and the widthwise inner end of the back body fabric 12. Since each inner thigh seam line 27 has the same configuration on the left and right, only the right inner thigh seam line 27 will be described in this embodiment.

[0035] Fig. 6 is a side view of pants 1 arranged so that each side fold line 71 and each thigh fold line 72 overlap, as viewed from the right thigh seam line 27 side. As shown in Fig. 6, each thigh seam line 27 is inclined forward as it goes from top to bottom. Each thigh seam line 27 is located forward of each thigh fold line 72 formed on the inner side in the width direction when the pants 1 is laid flat.

[0036] The inner thigh seam 27 has a first inner thigh seam 27a located at the upper part of the crotch tube portion 10b and a second inner thigh seam 27b located at the lower part of the crotch tube portion 10b. The first inner thigh seam 27a extends from the jumper line 61 to the knee line 62. The second inner thigh seam 27b extends from the knee line 62 to the hem portion 22.

[0037] The distance D6 between the upper end of the first inner thigh seam 27a and the inner thigh fold line 72 may be set to 1 mm or more and 9 mm or less, for example, 6 cm. The first inner thigh seam 27a extends in the vertical direction generally parallel to the inner thigh fold line 72.

[0038] The second inner thigh suture line 27b continues downward from the lower end of the first inner thigh suture line 27a. The second inner thigh suture line 27b may be inclined downward and forward. In this embodiment, the inner thigh inclination angle α2 of the second inner thigh suture line 27b with respect to the inner thigh fold line 72 is set to 1 degree.

[0039] As shown in Figs. 4 and 6, the distance D7 between the sixth intersection P7 of the first inner thigh seam 27a and the knee line 62 and the seventh intersection P8 of the inner thigh fold line 72 and the knee line 62 is preferably set to a length of 2.38% or more and 21.43% or less of the circumference D3 of the crotch tube part 10b at the knee line 62. In this embodiment, the distance D7 is set to, for example, 11.9% of the circumference D3. In this embodiment, since the circumference D3 is set to 42 cm, the distance D7 may be set to 1 cm or more and 9 cm or less, for example, 4 cm. If the distance D7 is less than 1 cm, it is difficult to obtain a shift of the fabric with respect to the knee part, and if it exceeds 9 cm, the inner thigh seam 27 is located on the front side in a standing posture (non-exercise posture), which may result in a poor appearance.

[0040] 5 and 6, the distance D8 between the eighth intersection P9 between the second inner thigh seam 27b and the hem 22 and the ninth intersection P10 between the inner thigh fold line 72 and the hem 22 is preferably set to a length of 2.7% to 24.3% of the circumference D5 of the crotch tube 10b at the hem 22. In this embodiment, the distance D8 is set to, for example, 12.2% of the circumference D5. In this embodiment, since the circumference D5 is set to 37 cm, the distance D8 may be set to 1 cm to 9 cm, for example, 4.5 cm.

[0041] As shown in Fig. 3, a gusset seam 28 is formed at the side seam 26, where the back body fabric 12 is gusseted relative to the front body fabric 11. The gusset seam 28 gives the back body fabric 12 a rounded shape, which increases the space on the buttocks side of the crotch tube portion 10a.

[0042] More specifically, in the side seam 26 before sewing, the distance of the rear shim stitching portion 28b from the hip line 63 of the back body fabric 12 to the crossover line 61 is set longer than the distance of the front shim stitching portion 28a from the hip line 63 of the front body fabric 11 to the crossover line 61. The front shim stitching portion 28a and the rear shim stitching portion 28b are sewn together in accordance with the front shim stitching portion 28a by shortening the rear shim stitching portion 28b. The rear shim stitching portion 28b may be set to be 0.5 cm to 1.0 cm longer than the front shim stitching portion 28a, for example, 1 cm. Instead of the shim stitching, darts may be formed, and in this case, the rear shim stitching portion 28b may be set to be 2.5 cm longer than the front shim stitching portion 28a.

[0043] In this specification, "shimming" refers to a technique in which the sewn part of one piece of fabric is made longer than the sewn part of the other piece of fabric, and the sewn part of the longer piece of fabric is shrunk to match the shorter piece, giving the longer piece a bulge. Since only the sewn part of the longer piece of fabric is shrunk and the rest of the fabric remains the same, a bulge that spreads out three-dimensionally from the sewn part is created.

[0044] In this embodiment, the hip line 63 is a straight line that is located at a position corresponding to the most rearward protruding part of the wearer's buttocks, for example, as shown by the dotted line in Figure 3, between the waist portion 21 and the jumper line 61, and is perpendicular to the side fold line 71.

[0045] 1 and 2, in this embodiment, pants 1 are made of a non-stretch fabric 9 made of a woven fabric, and are assumed to be worn without adhering to the wearer. The non-stretch fabric 9 preferably has a stress of 46.6 N or more and 308.7 N or less when stretched 30% in the body length direction (warp direction), and in this embodiment, for example, is 308.7 N. The non-stretch fabric preferably has a stress of 13.9 N or more and 64.7 N or less when stretched 30% in the body width direction (weft direction), and in this embodiment, for example, is 64.7 N. The upper and lower limits of the non-stretch fabric 9 will be described in detail in the examples.

[0046] The stress of the non-stretchable fabric 9 when stretched in the body length direction and body width direction was measured by preparing one piece of fabric in each of the warp and weft directions, 50 mm wide and 200 mm long, fixing the fabric to a tensile tester (Shimadzu Corporation: Autograph AGS-X) with a gripping width of 65 mm above and below and a gripping distance of 100 mm, stretching the fabric at a tensile speed of 200 mm / min, and reading the stress when the elongation rate was 30%. The stretchable fabric for which the tensile stress was measured corresponds to the fabric located on the front side of the wearer and covering the thighs, more specifically, corresponds to the test piece cut out from the area indicated by a and b in Figure 1.

[0047] FIG. 7 is a schematic diagram showing the back surface of the non-stretch fabric 9 used for the front body fabric 11 and the back body fabric 12 of the pants 1, which is positioned on the wearer side. As shown in FIG. 7, the non-stretch fabric 9 has a twill weave 90. The twill weave 90 is a weave in which the intersections of the warp and weft threads appear as diagonal lines, resembling ridges. The twill weave 90 is formed by weaving the warp threads 92 and the weft threads 93 not alternately, but by one of the warp threads 92 or the weft threads 93 crossing multiple other threads and being regularly shifted in the direction of the arrow W. In this specification, the diagonal ridges that make up the twill weave 90 are called twill stitches 91.

[0048] In this embodiment, the twill weave 90 is woven by repeatedly passing a weft 93 over two warp threads 92, and then under one warp thread 92. The portion where the weft 93 passes over the warp threads 92 without passing under them is more convex (protruding) than the portion where the weft 93 passes under the warp threads 92, forming a twill stitch 91. This makes the twill stitch 91 more likely to come into contact with the wearer. In other words, the contact area is smaller than when the entire fabric comes into contact with the wearer, as in a plain weave in which warp threads and weft threads are woven alternately.

[0049] The twill inclination angle θ1, which is the angle of the twill stitch 91 of the twill weave 90, may be set to 30 degrees or more and 60 degrees or less, more preferably 30 degrees or more and 45 degrees or less, and in this embodiment, it is set to, for example, 40 degrees. The twill inclination angle θ1 is the angle between the warp yarns 92 and the direction in which the twill stitch 91 extends.

[0050] In this embodiment, the warp threads 92 and the weft threads 93 are made of polyester, a blend of polyester and nylon, or a cotton material, preferably excluding urethane. The wire diameter of the weft threads 93 is set to be larger than the wire diameter of the warp threads 92. Compared to when the warp threads 92 and the weft threads 93 have the same wire diameter, the weft threads 93 are more convex toward the wearer, so that the portion made of the warp threads 92 is more likely to be prevented from coming into contact with the wearer.

[0051] Fig. 8 is a schematic diagram showing the non-stretch fabric 9 before the front body fabric 11 is cut. Fig. 9 is a schematic diagram showing the non-stretch fabric 9 before the back body fabric 12 is cut. Figs. 8 and 9 show the non-stretch fabric 9 arranged with the wearer-facing surfaces (reverse surfaces) of the front body fabric 11 and the back body fabric 12 on the side where the twill weave 91 is convex, visible. In Figs. 8 and 9, the warp and weft threads are omitted, and only the direction of the twill weave 91 is shown.

[0052] As shown in FIG. 8, the first twill weave 90a formed on the back surface of the left front body fabric 11a and the second twill weave 90b formed on the back surface of the right front body fabric 11b have different twill stitches 91. In this embodiment, the first twill weave 90a and the second twill weave 90b are line-symmetrical. More specifically, the direction of the first twill stitch 91a of the first twill weave 90a is inclined downward from the inner thigh seam 27 toward the left side seam 26. The direction of the second twill stitch 91b of the second twill weave 90b is inclined downward from the inner thigh seam 27 toward the right side seam 26. When the fabric 9 is viewed from the back surface, the first twill stitch 91a is inclined upward to the right, and the second twill stitch 91b is inclined upward to the left.

[0053] As shown in FIG. 9, the third twill weave 90c formed on the back surface of the left back body fabric 12a and the fourth twill weave 90d formed on the back surface of the right back body fabric 12b have different twill stitches 91. In this embodiment, the third twill weave 90c and the fourth twill weave 90d are line-symmetrical. More specifically, the direction of the third twill stitch 91c of the third twill weave 90c is inclined downward from the inner thigh seam 27 side toward the left side side seam 26 side. The direction of the fourth twill stitch 91d of the fourth twill weave 90d is inclined downward from the inner thigh seam 27 side toward the right side side seam 26 side. When the fabric 9 is viewed from the back surface, the third twill stitch 91c is inclined upward to the right, and the fourth twill stitch 91d is inclined upward to the left.

[0054] Next, a method for manufacturing the pants 1 will be described.

[0055] As shown in Figures 8 and 9, a non-stretch fabric (hereinafter also referred to as "fabric") 9 with a twill weave 90 on the back side is prepared. The fabric 9 has one side fabric 9a with one side twill weave 9c located on one side (left side in Figures 8 and 9) across the center line C in the width direction of the fabric 9, and another side fabric 9b with another side twill weave 9d located on the other side (right side in Figures 8 and 9). The one side twill weave 9c and the other side twill weave 9d are line symmetrical.

[0056] The one side twill weave 9c has a right twill stitch d1 that slopes downward from the center line C to one side and rises to the right. The other side twill weave 9d has a left twill stitch d2 that slopes downward from the center line C to the other side and rises to the left. The fabric 9 has an inverted V-shaped twill weave 90 composed of the right twill stitch d1 and the left twill stitch d2.

[0057] Fabric 9 having an inverted V-shaped twill weave 90 is dyed to a desired color using dyes and pigments. In the dyeing process, for example, the fabric is immersed in a dye solution to obtain a dyed fabric 9. A left front body fabric 11a and a left back body fabric 12a are cut from one side fabric 9a of the dyed fabric 9, and a right front body fabric 11b and a right back body fabric 12b are cut from the other side fabric 9b.

[0058] As shown in Fig. 8, in order to cut the left front body fabric 11a, the left front body pattern 31 is placed on one side fabric 9a. The left front body pattern 31 is the left front body fabric 11a in an unfolded state. The left front body fabric 11a is obtained by cutting the left body pattern 31a with the waist portion 21 facing upward, the inner thigh seam line 27 positioned on the center line C side, and the hem portion 22 and the knee line 62 positioned perpendicular to the longitudinal direction of the fabric 9.

[0059] To cut the right front body fabric 11b, the right front body pattern 32 is placed on the other-side fabric 9b. The right front body pattern 32 is the right front body fabric 11b in an unfolded state. The right front body fabric 11b is obtained by cutting the right front body pattern 32 with the waist portion 21 facing upward, the inner thigh seam line 27 positioned on the center line C side, and the hem portion 22 and the knee line 62 positioned perpendicular to the longitudinal direction of the fabric 9.

[0060] As shown in Fig. 9, in order to cut the left back body fabric 12a, the left back body pattern 33 is placed on one side fabric 9a. The left back body pattern 33 is the left back body fabric 12a in an unfolded state. The left back body fabric 12a is obtained by cutting the left back body pattern 33 with the hem 22 facing up, the inner thigh seam line 27 positioned on the center line C side, and the hem 22 and the knee line 62 positioned perpendicular to the longitudinal direction of the fabric 9.

[0061] To cut the right back body fabric 12b, the right back body pattern 34 is placed on the other side fabric 9b. The right back body pattern 34 is the right back body fabric 12b in an unfolded state. The right back body fabric 12b is obtained by cutting the right back body pattern 34 with the hem 22 facing up, the inner thigh seam 27 positioned on the center line C side, and the hem 22 and the knee line 62 positioned perpendicular to the longitudinal direction of the fabric 9.

[0062] By cutting as described above, a left front body fabric 11a having a first twill stitch 91a, a right front body fabric 11b having a second twill stitch 91b, a left back body fabric 12a having a third twill stitch 91c, and a right back body fabric 12b having a fourth twill stitch 91d are obtained as shown in Figures 8 and 9. In this embodiment, the right twill stitch d1 of one side fabric 9a constitutes the first twill stitch 91a and the third twill stitch 91c, and the left twill stitch d2 of the other side fabric 9b constitutes the second twill stitch 91b and the fourth twill stitch 91d.

[0063] The front rise seam 24 of the left front body fabric 11a and the right front body fabric 11b are sewn together to form the front body fabric 11. The back rise seam 25 of the left back body fabric 12a and the right back body fabric 12b are sewn together to form the back body fabric 12. The front body fabric 11 and the back body fabric 12 are overlapped with the front sides facing each other, sewn together at the inner thigh seam 27 and the side seam 26, and turned inside out to form the pants 1.

[0064] Fig. 10 is a left side view showing a state where the wearer wears the pants 1 in a standing position with knees extended. Fig. 11 is a left side perspective view showing a state where the wearer wears the pants 1 in an exercise position with legs bent and stretched. In the pants 1 in Fig. 11, the position of the knees K in the standard position in the standing position in Fig. 10 is indicated by K1, and the position of the knees K in the exercise position is indicated by K2.

[0065] As shown by the arrow A in FIG. 11, when the wearer bends and stretches his / her legs, the knees K move downward in the inner space of the crotch tube 10b of the pants 1 from the reference position K1 to the exercise position K2, while moving outward in the width direction. By bending and stretching, the knees K move downward in the inner space of the crotch tube 10b. By spreading the legs, the knees K move outward in the width direction in the inner space of the crotch tube 10b. Since the inner space of the crotch tube 10b is limited, when a certain knee K moves outward in the width direction, the knees K abut against the inner surface of the crotch tube 10b. When the knees K abut against the crotch tube 10b, the crotch tube 10b rotates (shifts) toward the inside in the width direction relative to the knees K. In other words, the crotch tube 10b rotates upward and inward (opposite to the arrow A) relative to the knees K as a whole.

[0066] Due to the rotation of the crotch sleeve 10b relative to the knee K, the side seam 26, which was located on the outer side in the width direction (outer thigh side) in the standard posture of Fig. 10, moves to the front side of the knee K in the exercise posture as shown in Fig. 11. When the side seam 26 that has moved to the front side of the knee K abuts against the knee K, the rotation of the crotch sleeve 10b stops and it does not slip relative to the knee K, which tends to inhibit the movement of the knee K.

[0067] In contrast, the pants 1 according to this embodiment have the following advantages.

[0068] (1) The pants 1 have, in at least a part of the garment covering the wearer's body, side seams 26, inner thigh seams 27, and / or twill weave 90 as slip-promoting parts that promote slippage of the pants 1 in a direction that makes it easier to move the joints when the wearer moves the joints, or suppress the pants 1 from being hindered from slipping in a direction that makes it easier to move the joints. According to this configuration, the slip-promoting parts provided in at least a part of the pants 1 allow the pants 1 to slip relative to the joints when the wearer moves the joints, so that the pants 1 are less likely to hinder the movement of the wearer's joints. Specifically, when the bent buttocks or knees K are further bent after coming into contact with the inner surfaces of the crotch tube 10a or crotch tube 10b of the pants 1, the crotch tube 10a or crotch tube 10b slip relative to the buttocks or knees K. This makes it possible to prevent tension from acting between the contact points, as would occur when the rise and crotch tube portions 10a and 10b are fixed to the buttocks and knees K without slipping.

[0069] (2) Pants 1 have a front body fabric 11 located in front of the wearer and a back body fabric 12 located at the back, and the slip-promoting portion is formed by a side seam line 26 where the front body fabric 11 and the back body fabric 12 are sewn together in a side view and which slopes downward and backward in a side view.

[0070] According to this configuration, when bending and stretching with legs apart, for example, the pants 1 shift upwards as a result of bending and stretching, and shift inward in the width direction as a result of legs apart. This shift causes the side seam 26 to approach the knee K, but since the side seam 26 is inclined downward and backward, the separation distance X2 between the side seam 26 and the knee K can be made longer than the separation distance X1 between the side seam 126, which extends roughly along the body length direction, and the knee K, as shown by the two-dot chain line in Fig. 8. This allows a larger margin for the side seam 26 to shift to the knee K, and prevents the side seam 26 from contacting the knee K and impeding the movement of the knee K.

[0071] (3) The slip-promoting portion is formed by sewing the front body fabric 11 and the back body fabric 12 together, and further includes an inner thigh seam 27 that is inclined downward and forward in a side view from the inside. With this configuration, the inner thigh seam is shifted forward to match the side seam that is shifted backward, so that the knee K after bending and spreading the legs can be positioned between the side seam and the inner thigh seam. This can suppress the knee K after bending and spreading the legs coming into contact with the side seam and the inner thigh seam.

[0072] (4) The distance D2 between the intersection (third intersection) P4 of the side seam line 26 and the knee line 62 and the intersection (second intersection) P3 of the side fold line 71 and the knee line 62 is set to a length of 3.57% to 17.9% of the circumference D3 of the crotch tube 10b at the knee line 62. According to this configuration, the knee K and the side seam line 26 can be appropriately separated, so that the side seam line 26 can be more effectively prevented from contacting the knee K during the exercise posture, thereby inhibiting the movement of the knee K. If the distance D2 is less than 3.57% of the circumference D3, the side seam line 26 will contact the knee K in the middle of the exercise posture, and the movement of the knee K will be easily inhibited at that point, making it difficult to feel a slippery feeling. If the separation distance D2 exceeds 17.9% of the circumference D3, the side seam line 26 will be spaced further rearward than the side fold line 71, which will tend to create slack in the front body fabric 11 in front of the side fold line 71. This will cause the front body fabric 11 to sag and wrinkle when in a non-aerial position (standing position), which may result in an unattractive appearance.

[0073] (5) The distance D7 between the intersection (sixth intersection) P7 of the inner thigh seam 27 and the knee line 62 and the intersection (seventh intersection) P8 of the inner thigh fold line 72 and the knee line 62 is set to a length of 2.38% to 21.43% of the circumference D3 of the crotch tube portion 10b at the knee line 62. According to this configuration, the inner thigh seam 27 can be shifted to match the side seam 26, so that the inhibition of movement of the knee portion K can be more effectively suppressed. If the distance D7 is less than 2.38% of the circumference D3, the inner thigh seam 27 approaches the inner thigh fold line 72, so that the front body fabric 11 is likely to become loose, and in a non-exercise posture (standing posture), the front body fabric 11 is likely to sag and wrinkle, which may result in a poor appearance. If the separation distance D7 exceeds 21.43% of the circumference D3, the inner thigh seam 27 approaches the armpit seam 26, making it difficult to position the knee K in the circumferential middle position between the inner thigh seam 27 and the armpit seam 26 in an athletic posture, which may cause tightness. Also, in a standing posture, the inner thigh seam 27 is located on the front side, which may result in a poor appearance.

[0074] (6) The garment has one side body fabric (left front body fabric 11a, left back body fabric 12a) located on one side in the width direction of the wearer and formed with one side twill weave 9c, and the other side body fabric (right front body fabric 11b, right back body fabric 12b) located on the other side in the width direction of the wearer and formed with the other side twill weave 9d, the one side twill weave 9c and the other side twill weave 9d are line symmetrical, and the slip-promoting portion is configured by providing the one side twill weave 9c and the other side twill weave 9d on the back side of the one side body fabric and the other side body fabric located on the wearer side. With this configuration, the contact area can be made smaller than when the entire fabric contacts the wearer, as in a plain weave fabric in which warp and weft threads constituting the fabric are woven alternately, and the fabric is more likely to slip relative to the wearer.

[0075] (7) In pants 1 having a front body fabric 11 located in front of the wearer, the slip-promoting portion is formed on the back surface facing the wearer in left front body fabric 11a located on the wearer's left side, and is composed of a right twill stitch d1 that slopes upward to the right from the outside in the width direction toward the inside, and a left twill stitch d2 that slopes upward to the left from the outside in the width direction toward the inside, on the back surface facing the wearer.

[0076] According to this configuration, the right twill stitch d1 and the left twill stitch d2 provided on the left front body fabric 11a and the right front body fabric 11b, respectively, reduce the contact area with the wearer compared to a fabric configured with a plain weave, for example, so that friction between the pants 1 and the wearer is reduced and rotation of the pants 1 is less likely to be hindered. The pants 1 are less likely to slip off the wearer during exercise, and hindering of exercise can be suppressed.

[0077] The directions of the right twill stitch d1 and the left twill stitch d2 on the left front body fabric 11a and the right front body fabric 11b, respectively, can facilitate the shifting of the pants 1 with respect to the knee region K when changing from the standard position to the exercise position. More specifically, since the direction of the twill stitch coincides with the movement direction of the fabric rotating upward and inward (opposite the direction of arrow A) with respect to the knee region K, it is easier to rotate the fabric along the direction of the twill stitch than when the direction of the twill stitch is different from the movement direction of the fabric.

[0078] (8) In pants 1 having a back body fabric 12 positioned on the back side of the wearer, the slip-promoting portion is formed on the back side facing the wearer in left back body fabric 12a positioned on the wearer's left side, with a left twill stitch d2 that slopes left from the outside in the width direction to the inside, and on the back side facing the wearer, with a right twill stitch d1 that slopes right from the outside in the width direction to the inside.

[0079] According to this configuration, the right twill stitch d1 and the left twill stitch d2 provided on the left back body fabric 12a and the right back body fabric 12b, respectively, reduce the contact area with the wearer compared to a fabric configured with a plain weave, for example, so that friction between the pants 1 and the wearer is reduced and rotation of the pants 1 is less likely to be hindered. The pants 1 are less likely to slip off the wearer during exercise, and hindering of exercise can be suppressed.

[0080] (9) The twill inclination angle θ1 of the right twill stitch d1 and the left twill stitch d2 is set to 30 degrees or more and 60 degrees or less, so that the twill inclination angle θ1 of the right twill stitch d1 and the left twill stitch d2 can be appropriately set along the movement direction of the fabric relative to the wearer. If the twill inclination angle θ1 is less than 30 degrees, the upward movement of the fabric is not easily promoted. If the twill inclination angle θ1 exceeds 60 degrees, the movement of the fabric in the width direction toward the inside is not easily promoted.

[0081] (10) Either the warp thread 92 or the weft thread 93 constituting the one side body fabric and the other side body fabric has a larger diameter than the other thread, and a twill loop is formed by one of the threads. With this configuration, since the diameter of one of the threads constituting the twill loop is set to be larger, it is easy to separate the other thread from the wearer, and it is easy to more effectively reduce the contact area of ​​the fabric with the wearer.

[0082] (11) The pants 1 are made of a non-stretch fabric 9, which means that compared to stretchable fabric, the pants are less able to follow the movements of the body and are more susceptible to cramps. However, the slip-promoting portion allows the fabric to shift relative to the joints, thereby preventing cramps.

[0083] (12) The position of the side seam 26 corresponding to the buttocks is provided with the gusset seam 28, which expands the space on the buttocks side of the wearer and increases the margin until the buttocks come into contact with the pants during exercise. This prevents the pants from pulling on the buttocks, making it less likely to impede movement of the buttocks.

[0084] (13) A method for manufacturing pants 1, in which pants 1 are manufactured by preparing a fabric having a twill structure that is linearly symmetrical on one side and the other side in the width direction, dyeing the fabric to obtain a dyed fabric, cutting one side body fabric from one side fabric portion located on one side of the dyed fabric, cutting the other side body fabric from the other side fabric portion located on the other side, and sewing the one side body fabric and the other side body fabric together.

[0085] According to this configuration, the one side body fabric and the other side body fabric are cut from a single piece of fabric. For example, if the one side body fabric and the other side body fabric are cut from separate pieces of fabric, color unevenness occurs between the one side body fabric and the other side body fabric due to differences in dyeing lots. In contrast, it is possible to manufacture pants that have line-symmetrical one side twill and other side twill while suppressing color unevenness between the one side body fabric and the other side body fabric due to differences in dyeing lots. EXAMPLES

[0086] The pants of the comparative example and the example were subjected to evaluation tests for stretchability and sensory evaluation. The results of these evaluation tests are shown in Table 1.

[0087] Comparative Example 1 is a pair of pants made of a woven fabric containing urethane with conventional stretchability. Example 1 is a pair of pants made of a non-stretch fabric that does not contain urethane and is plain woven with 100% polyester yarn. Example 2 is a pair of pants made of a non-stretch fabric that does not contain urethane and is twill woven with 100% polyester yarn, which has lower elasticity than Example 1.

[0088] The stretchability was evaluated by measuring the stress at 30% elongation. The sensory evaluation was performed by evaluating the ease of leg-spreading bending and stretching exercises for wearers wearing the pants of Comparative Example 1, Example 1, and Example 2. Specifically, the presence or absence of a feeling of tension and a feeling of slippage during leg-spreading bending and stretching exercises was evaluated. The "feeling of tension" was evaluated as the presence of a feeling of tension (x) when there was no slippage between the fabric and the knee, and the fabric was stretched by bending the knee. The "feeling of slippage" was evaluated as the absence of a feeling of slippage (x) when there was no movement of the fabric when it slipped against the knee.

[0089] [Table 1]

[0090] As is clear from Table 1, in the case of the conventional stretchable fabric containing urethane, the fabric does not slip relative to the knees during leg-split bending and stretching exercises due to the elasticity of the fabric, but the fabric is stretched by the bending of the knees, creating a feeling of tightness. In addition, since the fabric does not slip relative to the knees, the fabric is less likely to move when it slips relative to the knees, and therefore a feeling of slippage is not obtained. In Example 1, the stress at 30% elongation is higher and the elasticity is lower than in Comparative Example 1, so the fabric is more likely to slip relative to the knees during leg-split bending and stretching exercises. In addition, the fabric slips relative to the knees, so a feeling of slippage is also obtained. In Example 2, the stress at 30% elongation is higher and the elasticity is lower than in Example 1, so the fabric is more likely to slip relative to the knees during leg-split bending and stretching exercises. In addition, the fabric is more likely to slip relative to the knees, so a good feeling of slippage is also obtained. Furthermore, in Example 2, the weave has a twill weave, so the slippage of the fabric relative to the knees is further promoted. From the results in Table 1, it is preferable that the upper and lower limits of the stress when the fabric of pants 1 is stretched 30% in the body length direction (warp direction) are set to 46.6 N or more and 308.7 N or less, and the upper and lower limits of the stress when the fabric is stretched 30% in the body width direction (weft direction) are set to 13.9 N or more and 64.7 N or less.

[0091] In this embodiment, an example has been described in which the pants 1 are made of a non-stretch fabric 9, but the pants 1 may be made of a stretch fabric.

[0092] In this embodiment, the twill weave 90 is woven by repeatedly passing the weft thread 93 over two warp threads 92 and then under one warp thread 92, but this is not limited to the above. As in the first modified example shown in FIG. 12, the twill weave 190 may be configured with warp threads 192 and weft threads 193 in a 2 / 2 twill, or as in the second modified example shown in FIG. 13, the twill weave 290 may be configured with warp threads 292 and weft threads 293 in a 2 / 1 / 1 / 1 twill.

[0093] In this embodiment, the pants 1 are described as being made of a woven fabric, but may be made of a knitted fabric.

[0094] In this embodiment, an example has been described in which the side seam 26 and the twill weave 90 are provided as the slip promotion portion, but the slip promotion portion may be formed of either the side seam 26 or the twill weave 90.

[0095] In this embodiment, an example has been described in which clothing with a slip-promoting portion is applied to pants 1, but the present invention is not limited to this, and the clothing can be any pants whose hems extend below the knee (for example, short length pants such as below-the-knee length or three-quarter length), and the present invention can be applied to loose or tight clothing, etc., and the same effect as the present invention can be obtained.
