Description

[Technical Field]

[0001] The present disclosure relates to undergarments. [Background technology]

[0002] Functional clothing that promotes peripheral blood flow in the wearer to help the wearer recover from fatigue is known. For example, Patent Document 1 describes a blood flow-improving garment in which a front cover piece that covers the abdomen of the wearer is provided on the back surface with multiple protrusions containing far-infrared ceramic that emits far-infrared rays. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2014-201842 Summary of the Invention [Problem to be solved by the invention]

[0004] As described above, it is known that the use of functional fibers that emit far-infrared rays can improve the wearer's blood flow. Since the radiation energy of far-infrared rays is transmitted more efficiently the closer it is to the wearer's skin, in order to maximize the blood flow improvement effect, it is important to improve the fit of clothing so that the fabric containing the functional fibers adheres closely to the wearer's skin. On the other hand, excessively improving the fit of indoor wear such as pajamas and loungewear can lead to problems such as poor comfort and reduced wearability.

[0005] Therefore, an object of the present disclosure is to provide lower garments that can achieve both comfort and blood flow improvement function. [Means for solving the problem]

[0006] In one embodiment, the lower garment comprises a waist portion and a main body portion including a crotch portion and a pair of crotch portions, the waist portion including a ventral portion configured to cover the wearer's abdomen and a back portion configured to cover the wearer's back, each of the ventral portion and back portion including a lower edge joined to the crotch portion and an upper edge extending along the wearer's waistline above the lower edge, the ventral portion including far-infrared emitting fiber and having a tapered shape in which the width along the waistline decreases from the lower edge of the ventral portion toward the upper edge of the ventral portion, and the maximum width of the ventral portion in the waistline direction is smaller than the maximum width of the back portion in the waistline direction.

[0007] In the lower garment according to this embodiment, the maximum width of the abdominal portion in the waist direction is smaller than the maximum width of the back portion in the waist direction, preventing sagging or wrinkles from occurring in the abdominal portion. This allows the abdominal portion containing the far-infrared emitting fiber to be closely fitted to the wearer's abdomen, thereby increasing the radiation efficiency of far-infrared rays without using an elastic member or the like to improve fit. Therefore, this lower garment can achieve both comfort and blood flow improvement.

[0008] The abdominal portion includes a first outer panel and a second outer panel disposed on the side of the first outer panel that faces away from the wearer's skin, and each of the first outer panel and the second outer panel may contain far-infrared emitting fiber. By arranging the first outer panel and the second outer panel containing the far-infrared emitting fiber in an overlapping manner, blood flow in the abdominal portion of the wearer can be effectively improved.

[0009] The vertical width of the first outer panel may increase in a first direction along the waistline, and the vertical width of the second outer panel may increase in a second direction opposite to the first direction. By providing such first and second outer panel, the abdomen of the wearer can be covered in a close-fitting manner from an oblique direction, thereby effectively improving the wearer's blood flow.

[0010] The abdominal portion may further include an inner layer panel disposed on the wearer's skin side relative to the first outer layer panel, and the inner layer panel may include a far-infrared emitting fiber. By providing the inner layer panel including the far-infrared emitting fiber, blood flow in the abdominal portion of the wearer can be effectively improved.

[0011] The inner layer panel may have a multi-layer structure including two or more layers of fabric containing far-infrared emitting fiber. The first outer layer panel may have a multi-layer structure including two or more layers of fabric containing far-infrared emitting fiber. The second outer layer panel may have a multi-layer structure including two or more layers of fabric containing far-infrared emitting fiber. The inner layer panel, first outer layer panel, and second outer layer panel have a multi-layer structure, which can effectively improve blood flow in the abdominal area of ​​the wearer.

[0012] The abdominal portion includes a central region and an outer region disposed between the central region and the back portion in the waistline direction, and the inner layer panel, the first outer layer panel, and the second outer layer panel may be unjoined in the central region. By not joining the inner layer panel, the first outer layer panel, and the second outer layer panel in the central region, the inner layer panel, the first outer layer panel, and the second outer layer panel can move freely and easily conform to the wearer's body depending on the wearer's posture. As a result, the inner layer panel, the first outer layer panel, and the second outer layer panel are prevented from wrinkling, and the abdominal portion can be closely fitted to the wearer's abdomen.

[0013] The upper edge of the abdominal side portion may have a recess that is recessed toward the lower edge of the abdominal side portion. By forming such a recess, the apparent dimension of the upper edge of the abdominal side portion becomes longer, making it easier for the abdominal side portion to follow the bulge of the wearer's abdomen.

[0014] The vertical width of the abdominal portion may be equal to or greater than the vertical width of the crotch portion. By increasing the vertical width of the abdominal portion, the contact area of ​​the abdominal portion with the wearer's abdomen increases, thereby improving the blood flow improvement function of the abdominal portion.

[0015] The vertical width of the abdominal portion may be equal to or greater than the vertical width of the dorsal portion. The vertical width of the abdominal portion may be 7 cm or greater. Increasing the vertical width of the abdominal portion increases the contact area of ​​the abdominal portion with the wearer's abdomen, thereby enhancing the function of improving blood flow in the abdominal portion of the wearer. [Effects of the Invention]

[0016] According to the various aspects described above, it is possible to achieve both comfort and a blood flow improving function. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0018] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. In the description of the drawings, the same elements are designated by the same reference numerals, and duplicate explanations will be omitted. The drawings may be partially simplified or exaggerated for ease of understanding, and the dimensional ratios are not limited to those shown in the drawings.

[0019] The following describes a garment 1 according to one embodiment. The garment 1 is primarily worn indoors while sleeping or resting. The garment 1 is, for example, recovery wear that promotes recovery from fatigue in the wearer. The garment 1 contains a functional material that promotes blood flow in the wearer. In the following description, the "skin-facing side" refers to the side that faces the wearer's skin when the garment 1 is worn, and the "non-skin-facing side" refers to the side that faces away from the wearer's skin when the garment 1 is worn.

[0020] The garment 1 includes a lower garment 3. Fig. 1 is a front view of the lower garment 3 according to one embodiment. Fig. 2 is a rear view of the lower garment 3 shown in Fig. 1.

[0021] The lower garment 3 is a garment for covering the lower half of the wearer's body, and comprises a waist portion 50 and a main body portion 80. The waist portion 50 includes a ventral portion 51 and a dorsal portion 52. The ventral portion 51 covers the wearer's abdomen when worn. The dorsal portion 52 covers the wearer's back when worn. The ventral portion 51 and the dorsal portion 52 are formed into a tubular shape by sewing together both ends in the waist direction (circumferential direction around the wearer's waist).

[0022] Each of the abdominal portion 51 and the back portion 52 is made of fabric, such as woven fabric, knitted fabric, or nonwoven fabric. The fabrics that make up the abdominal portion 51 and the back portion 52 contain far-infrared emitting fibers. The far-infrared emitting fibers are fibers that carry a far-infrared emitting material that has the property of absorbing infrared rays emitted by the wearer and re-emitting that energy as far-infrared rays. Examples of far-infrared emitting materials include oxide ceramics, non-oxide ceramics, non-metals, metals, alloys, and crystals.

[0023] Examples of oxide ceramics include alumina (Al2O3), magnesia (MgO), zirconia (ZrO2), titanium oxide (TiO2), silicon dioxide (SiO2), chromium oxide (Cr2O3), ferrite (FeO2, Fe3O4), spinel (MgO·Al2O3), cerium (CaO2), and barium (BaO). Examples of non-oxide ceramics include carbide ceramics such as boron carbide (B4C), silicon carbide (SiC), titanium carbide (TiC), molybdenum carbide (MoC), and tungsten carbide (WC), as well as nitride ceramics such as boron nitride (BN), aluminum nitride (AlN), silicon nitride (Si3N4), and zirconium nitride (ZrN). Examples of non-metallic materials include carbon (C) and graphite. Metals include tungsten (W), molybdenum (Mo), vanadium (V), platinum (Pt), tantalum (Ta), manganese (Mn), nickel (Ni), copper oxide (CuO), and iron oxide (FeO). Alloys include nichrome, kanthal, stainless steel, and alumel. Crystals include mica, fluorite, calcite, alum, and quartz.

[0024] Far-infrared emitting fibers are produced by kneading a powder or granular far-infrared emitting substance with a particle diameter of 10 nm to 30 μm into fibers such as polyester. The far-infrared emitting substance may be fixed to the surface of the fibers by bonding with a binder (adhesive) or by chemically modifying the surface.

[0025] Since the abdominal portion 51 and the dorsal portion 52 contain far-infrared emitting fibers, the far-infrared rays emitted from the far-infrared emitting fibers promote blood circulation throughout the wearer's body.

[0026] The ventral portion 51 has an upper edge 51a and a lower edge 51b. The back portion 52 has an upper edge 52a and a lower edge 52b. Each of the ventral portion 51 and the back portion 52 has a tapered shape in which the width along the waist direction decreases from the lower edges 51b, 52b toward the upper edges 51a, 52a. The ventral portion 51 may have an elastic member such as flat elastic band provided along the upper edge 51a. The back portion 52 may have an elastic member such as flat elastic band provided along the upper edge 52a. Furthermore, the width of the lower edge 51b of the ventral portion 51 in the waist direction (the maximum width of the ventral portion 51) may be smaller than the width of the lower edge 52b of the back portion 52 in the waist direction (the maximum width of the back portion 52).

[0027] FIG. 3 shows a perspective view of the waist portion 50. As shown in FIG. 3, the abdominal portion 51 may include an inner layer panel 53, a first outer layer panel 54, and a second outer layer panel 55. The inner layer panel 53 has a trapezoidal shape when viewed from the front. The width of the inner layer panel 53 in the waist direction decreases toward the upper edge 51a. Both ends of the inner layer panel 53 in the waist direction are sewn along both ends of the back portion 52 in the waist direction. The inner layer panel 53 covers the abdomen of the wearer when worn.

[0028] As shown in FIG. 3 , the first outer panel 54 is disposed on the non-skin-facing side of the inner panel 53. Both ends of the first outer panel 54 in the waist direction are sewn to both ends of the back portion 52 in the waist direction. The second outer panel 55 is disposed on the non-skin-facing side of the first outer panel 54. Both ends of the second outer panel 55 in the waist direction are sewn to both ends of the back portion 52 in the waist direction. The first outer panel 54 and the second outer panel 55 have line-symmetric triangular shapes in a front view and intersect with each other at their centers. That is, the vertical width of the first outer panel 54 increases in a first direction along the waist direction. The vertical width of the second outer panel 55 increases in a second direction opposite the first direction. The first outer panel 54 and the second outer panel 55 extend in the waist direction so as to obliquely cover the wearer's abdomen.

[0029] Each of the inner layer panel 53, the first outer layer panel 54, and the second outer layer panel 55 contains far-infrared radiating fiber. By overlapping the inner layer panel 53, the first outer layer panel 54, and the second outer layer panel 55 containing far-infrared radiating fiber, the effect of promoting blood flow to the abdomen of the wearer is enhanced.

[0030] Each of the inner layer panel 53, the first outer layer panel 54, and the second outer layer panel 55 may have a multi-layer structure including two or more layers of fabric containing far-infrared emitting fibers. By making each of the inner layer panel 53, the first outer layer panel 54, and the second outer layer panel 55 have a multi-layer structure, the effect of promoting blood flow to the abdomen of the wearer can be further enhanced.

[0031] The abdominal portion 51 includes a central region and an outer region disposed between the central region and the back portion 52 in the waistline direction. In the central region, the inner layer panel 53, the first outer layer panel 54, and the second outer layer panel 55 may be unjoined. For example, the first outer layer panel 54 is unjoined to the inner layer panel 53 except at its opposite ends, and the second outer layer panel 55 is unjoined to the first outer layer panel 54 except at its opposite ends. This allows the inner layer panel 53, the first outer layer panel 54, and the second outer layer panel 55 to move freely and easily conform to the wearer's body depending on the wearer's posture. As a result, the inner layer panel 53, the first outer layer panel 54, and the second outer layer panel 55 are prevented from wrinkling.

[0032] The back portion 52 has a trapezoidal shape in a front view. The width of the back portion 52 in the waist direction decreases toward the upper edge 52a. The ventral portion 51 and the back portion 52 are sewn together along a pair of seams 57. The width d1 of the lower edge 51b of the ventral portion 51 in the waist direction is smaller than the width d2 of the lower edge 52b of the back portion 52 in the waist direction. Similarly, the width of the upper edge 51a of the ventral portion 51 in the waist direction is smaller than the width of the upper edge 52a of the back portion 52 in the waist direction. Therefore, the pair of seams 57 extend obliquely with respect to the central axis of the waist portion 50 and are positioned anterior (ventrally) to the coronal plane (the plane dividing the human body into front and rear) of the wearer.

[0033] In one embodiment, the height h1 of the inner layer panel 53 (the vertical width of the abdominal portion 51) may be equal to or greater than the height h2 of the back portion 52 (the vertical width of the back portion 52). For example, the height h1 of the inner layer panel 53 is greater than the height h2 of the back portion 52, and is equal to or greater than 7 cm. Increasing the height h1 of the inner layer panel 53 increases the contact area of ​​the inner layer panel 53 with the wearer's abdomen, thereby enhancing the blood flow improvement function.

[0034] The main body portion 80 includes a pair of leg portions 60. The pair of leg portions 60 are portions that cover the wearer's legs and are connected to the waist portion 50. Each of the pair of leg portions 60 is made of fabric such as woven fabric, knitted fabric, or nonwoven fabric. The fabric that makes up the pair of leg portions 60 contains far-infrared emitting fiber. Each of the pair of leg portions 60 includes a front leg portion 61 and a rear leg portion 71. The front leg portion 61 covers the wearer's leg from the front when worn. The rear leg portion 71 covers the wearer's leg from the rear when worn. The front leg portion 61 and the rear leg portion 71 are connected in the leg circumference direction (the circumferential direction around the wearer's leg) to form a cylindrical shape.

[0035] As shown in FIG. 1 , the front leg portion 61 includes a front main body portion 62 and a front hem portion 63. The front main body portion 62 includes a front crotch portion 62a and a front crotch portion 62b. The front crotch portion 62a covers the wearer's lower abdomen when worn. The front crotch portion 62b covers the wearer's thighs to near the ankles from the front when worn. The base end of the front crotch portion 62a is sewn to the lower edge 51b of the abdominal portion 51. The front crotch portion 62b is connected to the tip end of the front crotch portion 62a.

[0036] A front hem 63 is connected to the tip of the front crotch portion 62b. The front crotch portion 62a, the front crotch portion 62b, and the front hem 63 may be connected together seamlessly. The tip of the front hem 63 forms the hem edge 63a, which is the tip of the front leg portion 61. When worn, the front hem 63 covers the wearer's ankle from the instep side. In the leg circumference direction, the width of the front hem 63 may taper from the base end of the front hem 63 toward the hem edge 63a.

[0037] As shown in FIG. 2 , the rear leg portion 71 includes a rear main body portion 72 and a rear hem portion 73. The rear main body portion 72 includes a rear crotch portion 72a and a rear crotch portion 72b. The rear crotch portion 72a covers the wearer's buttocks when worn. The front crotch portion 62a and the rear crotch portion 72a are connected in the waist direction of the wearer to form a tubular crotch portion 82. The rear crotch portion 72b covers the wearer's thighs to near the ankles from the rear when worn. The front crotch portion 62b and the rear crotch portion 72b are connected in the waist direction of the wearer to form a tubular crotch portion 84. The base end of the rear crotch portion 72a is sewn to the lower edge 52b of the back portion 52. The rear crotch portion 72b is seamlessly and integrally connected to the tip end of the rear crotch portion 72a.

[0038] A rear hem 73 is connected to the tip of the rear crotch section 72b. The rear main body section 72 and the rear hem 73 are made of separate pieces of fabric and sewn together. The rear hem 73 covers the wearer's ankles from the rear when worn. The tip of the rear hem 73 provides the hem edge 73a, which is the tip of the rear leg section 71. The width of the rear hem 73 in the leg direction may taper from the base end of the rear hem 73 to the hem edge 73a. The front hem 63 and the back hem 73 are sewn together at their respective leg ends to form a ring-shaped hem C2 (see Figure 4).

[0039] As described above, the main body 80 includes the crotch portion 82 and a pair of crotch portions 84, and the crotch portion 82 is joined to the lower edge 51b of the abdominal portion 51 and the lower edge 52b of the back portion 52. In one embodiment, the height h1 of the inner layer panel 53 may be equal to or greater than the height h3 of the crotch portion 82 (the width of the crotch portion 82 in the vertical direction).

[0040] FIG. 4 is an enlarged view of the vicinity of the hem C2 of the lower garment 3. As shown in FIGS. 2 and 4, a drawstring section 75 is formed in the rear leg section 71 between the rear main body section 72 and the rear hem section 73, discontinuously reducing the diameter of each leg section 60. The drawstring section 75 can also be considered to be the seam between the rear main body section 72 and the rear hem section 73. The width of the tip of the rear main body section 72 before sewing in the leg direction is set larger than the width of the base of the back hem section 73 before sewing in the leg direction. The tip of the rear main body section 72 is sewn to match the width of the base of the back hem section 73. As a result, as shown in FIG. 4, excess fabric of the rear main body section 72 is gathered, and gathers are formed in the rear leg section 71 along the drawstring section 75.

[0041] On the other hand, the front main body portion 62 and the front hem portion 63 are smoothly connected without any seams. In other words, no narrowing portion is formed between the front main body portion 62 and the front hem portion 63.

[0042] The drawstring section 75 provides appropriate contraction to the hem C2 by utilizing the dimensional differences in the fabric itself, without using elastic materials such as rubber. As a result, friction between the hem C2 and the legs prevents the leg sections 60 from unexpectedly rolling up while sleeping. Furthermore, by forming the drawstring section 75 only on the rear leg section 71, the front hem 63, which faces the rear hem 73, is pressed against the front of the wearer's ankle and fits snugly around the ankle. The blood circulation-promoting effect of the far-infrared emitting fiber increases the closer the fiber is to the body. Therefore, by fitting the front hem 63, which includes the far-infrared emitting fiber, snugly around the wearer's ankle, heat radiation efficiency is maximized. This promotes peripheral blood vessel dilation and improves blood circulation in the toes.

[0043] In one embodiment, the distance D2 between the hem edge 73a of the back hem 73 and the tapered portion 75 along the longitudinal direction of each leg 60 may be 3 cm or more and 15 cm or less. By making the distance D2 between the hem edge 73a of the back hem 73 and the tapered portion 75 3 cm or more, the back hem 73 is positioned to cover the wearer's ankles when worn, thereby improving blood flow. On the other hand, by making the distance D2 between the hem edge 73a of the back hem 73 and the tapered portion 75 15 cm or less, most of the pair of legs 60 can be made loose, preventing an excessively tight fit. The distance D2 between the hem edge 73a of the back hem 73 and the tapered portion 75 along the longitudinal direction of each leg 60 may be 5 cm or more and 10 cm or less.

[0044] As shown in Figure 4, the front hem 63 may have a folded-back portion 65 at the hem edge 63a. The folded-back portion 65 is formed by folding back the fabric of the front hem 63. The length L2 of the folded-back portion 65 along the longitudinal direction of each leg 60 is, for example, between 1 cm and 15 cm.

[0045] FIG. 5 is an exemplary pattern development diagram for manufacturing the above-described lower garment 3. As shown in FIG. 5, the lower garment 3 is manufactured using a left front leg part 310, a left hind leg part 320, a right front leg part 330, a right hind leg part 340, a left hem part 350, a right hem part 360, a first front waist part 410, a second front waist part 420, a third front waist part 430, and a rear waist part 440.

[0048] The right front leg part 330 includes an upper edge 331, a lower edge 332, a first side edge 333, a second side edge 334, and a crotch edge 335. One end of the first side edge 333 is connected to one end of the upper edge 331, and the other end of the first side edge 333 is connected to one end of the lower edge 332. One end of the crotch edge 335 is connected to the other end of the upper edge 331. One end of the second side edge 334 is connected to the other end of the crotch edge 335, and the other end of the second side edge 334 is connected to the other end of the lower edge 332.

[0049] The right hind leg part 340 includes an upper edge 341, a lower edge 342, a first side edge 343, a second side edge 344, and a crotch edge 345.

One end of the second side edge 344 is connected to the other end of the crotch edge 345, and the other end of the second side edge 344 is connected to the other end of the lower edge 342.

[0050] The left hem part 350 is formed in a substantially rectangular shape. The left hem part 350 includes an upper edge 351, a lower edge 352, a first side edge 353, and a second side edge 354. One end of the first side edge 353 is connected to one end of the upper edge 351, and the other end of the first side edge 353 is connected to one end of the lower edge 352. One end of the second side edge 354 is connected to the other end of the upper edge 351, and the other end of the second side edge 354 is connected to the other end of the lower edge 352. The length of the upper edge 351 is shorter than the length of the lower edge 322 of the left hind leg part 320. The width of the left hem part 350 (the distance between the first side edge 353 and the second side edge 354) narrows from the upper edge 351 toward the lower edge 352. In other words, the left hem part 350 has a tapered shape.

[0051] The right hem part 360 is formed in a substantially rectangular shape. The right hem part 360 includes an upper edge 361, a lower edge 362, a first side edge 363, and a second side edge 364. One end of the first side edge 363 is connected to one end of the upper edge 361, and the other end of the first side edge 363 is connected to one end of the lower edge 362. One end of the second side edge 364 is connected to the other end of the upper edge 361, and the other end of the second side edge 364 is connected to the other end of the lower edge 362. The length of the upper edge 361 is shorter than the length of the lower edge 342 of the right hind leg part 340. The width of the right hem part 360 (the distance between the first side edge 363 and the second side edge 364) narrows from the upper edge 361 to the lower edge 362. In other words, the right hem part 360 has a tapered shape. As shown in FIG. 6, the left hem part 350 and the right hem part 360 may have a multi-layer structure in which a single piece of fabric is folded along a fold line FL1 to overlap the fabric.

[0052] The first front waist part 410 is formed in a substantially trapezoidal shape. The first front waist part 410 may have a multi-layer structure in which two or more layers are superimposed by folding a single piece of fabric. The first front waist part 410 includes an upper edge 411, a lower edge 412, a first side edge 413, and a second side edge 414. One end of the first side edge 413 is connected to one end of the upper edge 411, and the other end of the first side edge 413 is connected to one end of the lower edge 412. One end of the second side edge 414 is connected to the other end of the upper edge 411, and the other end of the second side edge 414 is connected to the other end of the lower edge 412. The length of the upper edge 411 is shorter than the length of the lower edge 412. Therefore, the width of the first front waist part 410 in the waist direction narrows as it approaches the upper edge 411. In other words, the first front waist part 410 has a tapered shape. As shown in FIG. 7, the first front waist part 410 may have a multi-layer structure in which a single piece of fabric is folded along a fold line FL2 to overlap the fabric.

[0053] The second front waist part 420 and the third front waist part 430 are formed in a substantially triangular shape. Each of the second front waist part 420 and the third front waist part 430 may have a multi-layer structure in which two or more layers are superimposed by folding a single piece of fabric. The vertical width of the second front waist part 420 increases toward a first direction along the waistline direction. The vertical width of the third front waist part 430 increases toward a second direction opposite to the first direction.

[0054] The rear waist part 440 is formed in a substantially trapezoidal shape. The rear waist part 440 may have a multi-layer structure in which two or more layers are superimposed by folding a single piece of fabric. The rear waist part 440 includes an upper edge 441, a lower edge 442, a first side edge 443, and a second side edge 444. One end of the first side edge 443 is connected to one end of the upper edge 441, and the other end of the first side edge 443 is connected to one end of the lower edge 442. One end of the second side edge 444 is connected to the other end of the upper edge 441, and the other end of the second side edge 444 is connected to the other end of the lower edge 442. The length of the upper edge 441 is shorter than the length of the lower edge 442. Therefore, the width of the rear waist part 440 in the waistline direction narrows as it approaches the upper edge 441. In other words, the rear waist part 440 has a tapered shape. As shown in FIG. 8, the rear waist part 440 may have a multi-layer structure in which a single piece of fabric is folded along a fold line FL3 to overlap the fabric.

[0055] To manufacture the lower garment 3, the lower edge 322 of the left hind leg part 320 is sewn along the upper edge 351 of the left hem part 350. At this time, because the length of the lower edge 322 is longer than the length of the upper edge 351, the excess fabric of the left hind leg part 320 is gathered together during sewing, forming gathers along the seam. By sewing them together in this manner, the left hind leg part 320 becomes the rear main body part 72, and the left hem part 350 becomes the rear hem part 73, and a drawstring part 75 is formed between the rear main body part 72 and the rear hem part 73. Similarly, the lower edge 342 of the right hind leg part 340 is sewn along the upper edge 361 of the right hem part 360. At this time, because the length of the lower edge 342 is longer than the length of the upper edge 361, the excess fabric of the right hind leg part 340 is gathered together during sewing, forming gathers along the seam. By sewing in this manner, the right rear leg part 340 becomes the rear main body part 72, the right hem part 360 becomes the rear hem part 73, and a drawstring part 75 is formed between the rear main body part 72 and the rear hem part 73.

[0056] Parts of the first side edge 313 and the second side edge 314 of the left front leg part 310 are sewn along the first side edge 323 and the second side edge 324 of the left hind leg part 320, respectively. Other parts (tips) of the first side edge 313 and the second side edge 314 of the left front leg part 310 are sewn along the first side edge 353 and the second side edge 354 of the left hem part 350, respectively. By sewing the left front leg part 310, the left hind leg part 320, and the left hem part 350 in this manner, the left leg part 60 including the front leg portion 61 and the rear leg portion 71 is formed. Similarly, parts of the first side edge 333 and the second side edge 334 of the right front leg part 330 are sewn along the first side edge 343 and the second side edge 344 of the right hind leg part 340, respectively. Other parts (tips) of the first side edge 333 and the second side edge 334 of the right front leg part 330 are sewn along the first side edge 363 and the second side edge 364, respectively, of the right hem part 360. By sewing the right front leg part 330, the right hind leg part 340, and the right hem part 360 in this way, the right leg part 60 including the front leg portion 61 and the hind leg portion 71 is formed.

[0057] Furthermore, the crotch edge 315 of the left front leg part 310 and the crotch edge 335 of the right front leg part 330 are sewn together, and the crotch edge 325 of the left hind leg part 320 and the crotch edge 345 of the right hind leg part 340 are sewn together. In this way, the pair of legs 60 are joined together.

[0058] A first side edge 413 and a second side edge 414 of the first front waist part 410 are sewn together along a first side edge 443 and a second side edge 444 of the back waist part 440. The second front waist part 420 and the third front waist part 430 are arranged on the non-skin-facing side of the first front waist part 410, and both end portions of the second front waist part 420 and the third front waist part 430 are sewn together along a first side edge 443 and a second side edge 444 of the back waist part 440. By sewing together the first front waist part 410, the second front waist part 420, the third front waist part 430, and the back waist part 440 in this way, a waist part 50 including a belly part 51 and a back part 52 is formed.

[0059] The upper edge 311 of the left front leg part 310 and the upper edge 331 of the right front leg part 330 are sewn together along the lower edge 412 of the first front waist part 410. The upper edge 321 of the left hind leg part 320 and the upper edge 341 of the right hind leg part 340 are sewn together along the lower edge 442 of the rear waist part 440. In this manner, the lower garment 3 including the waist part 50 and the pair of leg parts 60 is produced.

[0060] FIG. 9 is a perspective view of the hem portion C2 of the lower garment 3 worn by a wearer. As described above, in the lower garment 3, the tapered portion 75 is formed between the rear main body portion 72 and the rear hem portion 73 of the rear leg portion 71, discontinuously narrowing the diameter of the leg portion 60 in the direction of the wearer's leg. By narrowing the leg portion 60 at the rear of the hem portion C2, the front hem portion 63, which faces the rear hem portion 73, is pressed against the wearer's ankle from the front, providing a surface-to-surface fit. This allows the front hem portion 63 to fit snugly against the wearer's instep, maximizing the heat radiation efficiency of the far-infrared radiation fiber contained in the front hem portion 63 and promoting the dilation of the wearer's peripheral blood vessels. This promotes blood circulation in the wearer's feet and helps the wearer recover from fatigue.

[0061] On the other hand, because the front hem 63 is not tapered, the wearer's toes can pass through smoothly when putting on or taking off the garment, preventing the toes from getting caught. Furthermore, because the diameter of the pair of leg sections 60 is not tapered in the portions proximal to the tapered section 75, excessive tightness around the wearer's calves and thighs is prevented when the garment is worn. This improves the comfort of the lower garment 3.

[0062] Furthermore, in the lower garment 3 described above, the maximum width of the abdominal portion 51 in the waist direction is smaller than the maximum width of the back portion 52 in the waist direction, preventing sagging or wrinkles from occurring in the abdominal portion 51. This allows the abdominal portion 51, which contains far-infrared emitting fibers, to be closely fitted to the wearer's abdomen, thereby improving the radiation efficiency of far-infrared rays without using elastic members or the like to improve fit. Therefore, this lower garment 3 can achieve both comfort and a blood flow-improving function.

[0063] 1 includes an inner layer panel 53, a first outer layer panel 54, and a second outer layer panel 55, but in one embodiment, the abdominal side portion 51 may not include the inner layer panel 53, but may include only the first outer layer panel 54 and the second outer layer panel 55. Alternatively, the abdominal side portion 51 may not include the first outer layer panel 54 and the second outer layer panel 55, but may include only the inner layer panel 53.

[0064] Fig. 10 is a front view of an undergarment 3A having only an inner layer panel 53 as the abdominal portion 51. As shown in Fig. 10, an upper edge 51a of the abdominal portion 51 of the lower garment 3A may be formed with a recess 56 that recesses toward the lower edge 51b of the abdominal portion 51. By forming the recess 56 in the abdominal portion 51, the apparent dimension of the upper edge 51a of the abdominal portion 51 becomes longer, making it easier to follow the expansion of the wearer's abdomen.

[0065] While the garment 1 according to various embodiments has been described above, the present invention is not limited to the above-described embodiments and various modifications can be made without departing from the spirit of the invention. In other words, it should be noted that the above-described embodiments are for illustrative purposes only and do not limit the scope of the present invention.

[0066] For example, in the above-described embodiment, the entire lower garment 3 is made of fabric containing far-infrared emitting fiber, but it is sufficient that the far-infrared emitting fiber is contained at least in the abdominal portion 51 of the lower garment 3. The various embodiments described above can be combined within a consistent range.
