Description

[Technical Field]

[0001] The present invention relates to lower-body garments, such as boxer shorts, which are lower-body undergarments that cover the abdomen and buttocks. The lower-body garments easily follow the movement of the wearer's body (especially the waist) and are resistant to slipping (falling down) and can prevent shirts or other items worn on the outside of the lower-body garments from rolling up. The present invention particularly relates to lower-body garments equipped with a garment band for achieving this function, and to such garment bands (sometimes referred to as waist elastic, waistbands, or woven elastic). The lower-body garments referred to in the present invention are not limited to those for men or women, and may be any lower-body garment that covers at least the abdomen and buttocks. If the garments have leg sections, the length of the garment is not particularly limited. The garments may be worn as underwear or for sports, and their uses are not limited to these. The "abdomen" primarily refers to the lower abdomen. In addition, in the description of this invention, the knitted fabric that constitutes the lower body garment, excluding the clothing band, is described without distinguishing it from fabric (even when it is described as fabric, it indicates that it is a stretchable knitted fabric), and the fabric that constitutes the clothing band is described as woven fabric (to distinguish it from fabric and knitted fabric). [Background technology]

[0002] There are known lower-body garments that use fabrics with high elasticity (stretches well and shrinks well) and / or fabrics with high compression strength (tightly stretches and fits closely to the body). Knitted fabrics are particularly preferred for this purpose due to their elasticity. One example of such lower-body garments is underwear. Underwear ensures a good fit with uniform pressure distribution, does not feel tight or loose during body movement, and improves the appearance of the garment when worn.

[0003] Boxer shorts, one type of underwear, are made by sewing together fabric pieces for the body, gusset, and placket, which are cut along a flat standard pattern. These fabric pieces are often made of weft-knitted fabrics such as rib knitting, which are stretchable so as not to hinder movement during the various activities of daily life.

[0004] Furthermore, in such boxer shorts, pieces of fabric cut along a flat pattern that resembles a projection of the body onto a plane are sewn together to form a three-dimensional shape, which conforms as closely as possible to the complex three-dimensional curves of the human abdomen, buttocks, and legs, achieving both a comfortable fit (easy fit) and a non-restrictive feeling (stress-free).However, when lower-body clothing such as boxer shorts is worn, for example, by a middle-aged man with a protruding abdomen, there is a problem in that the boxer shorts slip off the wearer's body with movement of the lower body, or a shirt worn on the outside of the boxer shorts rolls up, resulting in an unattractive appearance.

[0005] Although not applicable to boxer shorts like this, a clothing elastic cuff structure that is applicable to women's above-the-knee leggings to prevent the lower-body garment itself from slipping down from the wearer's body is disclosed in Utility Model Registration Publication No. 3185291 (Patent Document 1). The clothing elastic cuff structure (including lower-body underwear) disclosed in Patent Document 1 comprises an elastic cuff that extends over a predetermined width upward from the upper end of a garment main body that covers a part of the body, and is characterized in that the upper end of the garment main body is formed continuously upward to form an elastic cuff-forming section that is knitted in the same way as the garment main body, and the elastic cuff is formed by applying an elastic material that is stretchable like rubber at least at room temperature and prevents slipping down to part or all of the inside of the elastic cuff-forming section, and is characterized in that the elastic material includes at least urethane rubber, silicone rubber, or natural rubber.

[0006] In addition, Japanese Patent Application Laid-Open No. 2020-153054 (Patent Document 2) solves the problem that when a shirt or T-shirt or other outer garment is tucked into the waist area of pants and the body is moved for a certain period of time, a part of the outer garment tucked into the waist area of pants slips up and slides out, or the outer garment bulges out, resulting in a lack of aesthetic appeal (preventing a shirt or the like worn on the outside of lower body clothing from rolling up). The pants disclosed in Patent Document 2 are pants with a function to prevent clothing from slipping down, and include a waist opening, two thigh openings, a gusset section provided between the two thigh openings, and a waist ring section provided in the vicinity of the waist opening, and the waist ring section has elasticity that stretches in the circumferential direction, and the waist ring section and the upper end of the pants are connected by a connecting section, and the waist ring section includes a first band section and a second band section that are connected to each other, and a pleated section is provided between the first band section and the second band section, and the first band section is selected. The first band portion is folded in a manner that allows the first band portion to be ... [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Utility Model Registration Publication No. 3185291 [Patent Document 2] Japanese Patent Publication No. 2020-153054 Summary of the Invention [Problem to be solved by the invention]

[0008] However, the structure of the clothing cuff elastic disclosed in the above-mentioned Patent Document 1 merely prevents the clothing from slipping down from the wearer's body by applying an elastic material to the inside of the cuff elastic forming part, and does not prevent the shirt or the like worn on the outside of the lower body clothing from rolling up. In addition, there are problems in that the silicone rubber or urethane rubber applied as the elastic material comes into direct contact with the skin, which may result in a poor wearing comfort or the risk of skin irritation.

[0009] Furthermore, the pants disclosed in Patent Document 2 merely prevent the jacket from rubbing upward by attaching a frictional anti-slip member to the garment outside the waist ring, but cannot prevent the garment from slipping down from the wearer's body. To prevent both the pants body disclosed in Patent Document 2 from slipping down from the wearer's body and the shirt or other garment outside the pants from rolling up, it is necessary to provide anti-slip material on both the front and back, but this raises problems such as increased costs and a poor appearance.

[0010] The present invention was developed in consideration of the above-mentioned problems of the prior art, and its purpose is to provide a clothing band that is suitable for use in lower-body clothing that mainly covers the abdomen and buttocks, which allows the lower-body clothing to easily follow the movement of the wearer's body (particularly the waist) as the lower body moves, is less likely to slip off (is less likely to slip down), prevents shirts and the like worn on the outside of the lower-body clothing from rolling up, and prevents the clothing from looking unattractive, and has an aesthetically pleasing appearance, as well as a lower-body clothing that uses this clothing band. [Means for solving the problem]

[0011] In order to achieve the above object, a clothing band according to one aspect of the present invention employs the following technical means.

[0012] That is, a clothing band according to one aspect of the present invention is a clothing band that prevents the clothing from slipping off the body of the wearer on the skin side of the clothing, and prevents an outer garment that is more outer than the clothing from slipping on the anti-skin side of the clothing, and is characterized in that the clothing band is formed from woven rubber, and the woven rubber uses synthetic fiber yarns of 100 to 200 dtex / 30 to 100 F for the weft, and synthetic fiber yarns of 100 to 200 dtex / 30 to 100 F and ultrafine polyester fiber yarns with a single fiber diameter of 1000 nm or less for the warp, and the ultrafine polyester fiber yarns are exposed on both the front and back of the woven rubber.

[0013] Preferably, the woven rubber can be configured to use the synthetic fiber yarn as a pattern thread of the warp and the ultra-fine polyester fiber yarn as a ground thread of the warp.

[0014] More preferably, the synthetic fiber yarn used as the pattern yarn of the warp yarn can be a lustrous nylon yarn or a lustrous polyester yarn.

[0015] More preferably, the woven rubber can be configured so that the non-slip portion knitted with the ground yarn and the design portion knitted with the pattern yarn alternate on the front and back sides of the woven rubber in a striped or lattice pattern along the longitudinal direction of the clothing band.

[0016] More preferably, in a comparison between a first woven rubber having the striped pattern and a second woven rubber having no comparative pattern but formed with the same yarn usage and yarn type except that the ultrafine polyester fiber yarn is not used, the first woven rubber has a three-tiered striped pattern of the non-slip portion, the design portion and the non-slip portion on the front side, and a three-tiered striped pattern of the design portion, the non-slip portion and the design portion on the back side, with the measurement direction perpendicular to the longitudinal direction, measurements are taken on the front and back of the first woven rubber to calculate an average value, while the second woven rubber has the same pattern on both the front and back, so measurements are taken on only one of the front and back, and the first woven rubber can be configured to have a surface friction coefficient MIU that is 10% or more higher, a surface friction coefficient variation MMD that is 200% or more higher, or a surface roughness SMD that is 40% or more higher than the second woven rubber.

[0017] More preferably, in a comparison between a first woven rubber having the striped pattern and a second woven rubber having no comparative pattern but formed with the same yarn usage and yarn type except that the ultrafine polyester fiber yarn is not used, the first woven rubber has a three-tiered striped pattern of the non-slip portion, the design portion and the non-slip portion on the front side and a three-tiered striped pattern of the design portion, the non-slip portion and the design portion on the back side, and the measurement direction is perpendicular to the longitudinal direction, and measurements are made on the front and back of the first woven rubber to calculate an average value, while since the second woven rubber has the same pattern on both the front and back, measurements are made on only one of the front and back, and the first woven rubber has a static friction coefficient μs that is 30% or more higher, a dynamic friction coefficient μk that is 20% or more higher, or a standard deviation D of the frictional resistance force (gf) that is 60% or more higher than the second woven rubber.

[0018] In addition, a lower body garment relating to another aspect of the present invention is a lower body garment in which the edges of one or more stretchable knitted fabrics are joined, and is characterized in that a clothing band as described above is attached to the waist portion with the longitudinal direction of the clothing band in the direction around the waist.

[0019] Preferably, the lower body garment can be configured as boxer shorts that cover at least the lower abdomen and buttocks. [Effects of the Invention]

[0020] According to the present invention, a clothing band is provided that is suitable for use in lower-body clothing that mainly covers the abdomen and buttocks, and the lower-body clothing easily follows the movement of the wearer's body (particularly the waist) in response to movement of the lower body, and is less likely to slip (fall off), preventing shirts and the like worn on the outside of the lower-body clothing from rolling up and making the clothing look unattractive.In addition, it is possible to provide a clothing band that has an aesthetic appearance, and lower-body clothing that uses this clothing band.

[0022] Boxer shorts (short type) as an example of lower-body clothing according to an embodiment of the present invention will be described in detail below with reference to Fig. 1. Note that the boxer shorts (an example of lower-body clothing) shown in Fig. 1 have short leg portions, but when lower-body clothing according to the present invention has leg portions, the length of the leg portions is not particularly limited, and for example, the lower-body clothing according to the present invention may be a long type whose length reaches just above the knees. In this way, the lower-body clothing according to the present invention is not limited to boxer shorts, but may be any lower-body clothing that primarily covers the abdomen and buttocks, or may be lower-body clothing that also covers the legs, and when leg portions are included, the length of the leg covering is not limited as described above.

[0023] Here, boxer shorts 100 shown in FIG. 1 are an example of lower-body garments according to an embodiment of the present invention, equipped with a clothing band WB according to an embodiment of the present invention at the waist. FIG. 1(A) shows a front view (ventral side) of the boxer shorts 100 placed on a flat surface (ideal or virtual), and FIG. 1(B) shows a rear view (back side). The (ideal or virtual) state of being placed on a flat surface means, for example, that these figures are not symmetrical, do not show the three-dimensional shape of the bulging portions, etc. The boxer shorts according to this embodiment, which are an example of lower-body garments according to the present invention, are made of a stretchable fabric. Therefore, if they are not illustrated as such, they will be partially shrunk or partially stretched, making it difficult to understand their shape. Therefore, the above-described assumptions are used.

[0024] The boxer shorts 100 shown in Fig. 1 are an example of a lower-body garment that covers at least the lower abdomen and buttocks, and is made by joining the edges of one or more stretch knit fabrics (this joining is not limited to being by sewing or adhesive), and includes a body fabric B that covers at least a portion of the lower abdomen and buttocks, and a clothing band WB according to the present invention, which will be described in detail later, around the torso (waist portion, hips), and further includes a bulge portion (front placket) formed by a placket fabric F, and side portions formed on the left and right of the bulge portion (front placket) by side knit fabric S. Note that while the lower-body garment according to the present invention must include the clothing band according to the present invention, it is not necessary to include the bulge portion (front placket) formed by the placket fabric F and / or side portions formed on the left and right of the bulge portion (front placket) by side knit fabric S, and it is also possible to include a thick portion (crotch portion) formed by a thick knit fabric. In other words, the boxer shorts shown in Figure 1 are merely one example of lower body clothing according to the present invention, and the configuration of the boxer shorts (other than the essential requirement that they include the clothing band according to the present invention) is also merely one example.

[0025] The clothing band WB prevents the clothing (here, boxer shorts 100, an example of lower-body clothing) from slipping off the wearer's body on the skin side of the clothing, and also prevents an outer garment from slipping off the opposite side of the clothing. The clothing band WB is made of woven rubber. The woven rubber uses synthetic fiber yarns of 100 to 200 dtex / 30 to 100 F for the weft and synthetic fiber yarns of 100 to 200 dtex / 30 to 100 F and ultrafine polyester fiber yarns (sometimes referred to as microfibers) with a single fiber diameter of 1000 nm or less for the warp, with the ultrafine polyester fiber yarns exposed on both the front and back of the woven rubber.

[0026] The front (opposite side to the skin) of the clothing band WB placed on a flat surface is shown in Figure 2(A), and the back (skin side) is shown in Figure 2(B). As shown in Figure 2, the clothing band WB is woven using warp yarns (ground yarns, pattern yarns) and weft yarns to create a beautiful pattern. The anti-slip area WB10, where ultrafine polyester fiber yarns with a single fiber diameter of 1000 nm or less used as warp yarns are exposed, and the design area WB20, where synthetic fiber yarns of 100 to 200 dtex / 30 to 100 F (where the ultrafine polyester fiber yarns are not exposed) are used as warp yarns, are striped in the longitudinal direction of the clothing band WB and appear alternately in reverse order on the front and back (the opposite side of the front anti-slip area WB10 is the back design area WB20, and the opposite side of the front design area WB20 is the back anti-slip area WB10). The pattern of the clothing band WB is not limited to a striped pattern (a checkered pattern like a checkered flag) and may be a grid pattern (a checkered pattern like a checkered flag) or other patterns (patterns) (preferably aesthetic), but the anti-slip portion WB10 where ultra-fine polyester fiber threads are exposed on both the front and back of the clothing band WB (woven rubber) must be present on the surface. The width of the clothing band WB (the length in the measurement direction shown in FIG. 2, etc.) is 40 mm, although this is not limited thereto.

[0027] As will be described in detail later, the woven rubber forming the clothing band WB uses synthetic fiber yarns of 100-200 dtex / 30-100F as the warp pattern yarns and ultrafine polyester fiber yarns with a single fiber diameter of 1000 nm or less as the warp ground yarns. An example of ultrafine polyester fiber yarns is an island-in-sea composite split yarn (island-in-sea microfiber) as an ultrafine fiber. Fabrics using such ultrafine fibers are characterized by a high coefficient of friction on the fabric surface, and may be referred to as non-slip polyester below. Here, although not limited to, The ultrafine polyester fiber yarn used as the warp yarn (ground yarn) has a single fiber diameter of preferably 10 nm to 900 nm, and particularly preferably 500 nm to 800 nm, and the number of filaments is preferably 500 F to 5000 F, and particularly preferably 1500 F to 2000 F, The fineness of the synthetic fiber yarns used as the warp threads (pattern yarns) is preferably 10 dtex or more and 500 dtex or less, and more preferably 100 dtex or more and 300 dtex or less, and the number of filaments is preferably 10F or more and 200F or less, and more preferably 20F or more and 60F or less, The fineness of the synthetic fiber yarn used as the weft is preferably 10 dtex to 500 dtex, and more preferably 100 dtex to 300 dtex, and the number of filaments is preferably 10 F to 200 F, and even more preferably 20 F to 60 F. Furthermore, the synthetic fiber yarn used as the pattern yarn for the warp is preferably a glossy nylon yarn or a glossy polyester yarn, and a glossy nylon yarn is especially preferred. The clothing band WB shown in Figure 2 has a non-slip area WB10 knitted with a base yarn and a glossy design area WB20 knitted with a pattern yarn, which are repeated in stripes (here, three rows) to create an aesthetic appearance.

[0028] Below, we will explain the clothing bands WB according to two examples, a comparative example that serves as a control for these examples, and the evaluation results. The only difference between Example 1 and Example 2 is that the clothing band WB according to Example 1 has a black non-slip portion and a silver design portion, while the clothing band WB according to Example 2 has a blue non-slip portion and a white design portion. The comparative example is a comparative clothing band made with the same yarn and thread type, except that it does not use ultrafine polyester fiber yarn (non-slip polyester, as described below). Examples 1 and 2 have a three-tiered striped pattern of non-slip portion WB10, design portion WB20, and non-slip portion WB10 on the front side, and a three-tiered striped pattern of design portion WB20, non-slip portion WB10, and design portion WB20 on the back side. The comparative example has no pattern (it is entirely composed of design portions). The measurement direction in the evaluation test described later is the widthwise direction of the clothing band WB shown in FIG. 2 (the vertical direction of the waist, the direction in which the boxer shorts 100 slip down) (the same applies to the comparative example).

[0029] <Examples 1 and 2> Warp thread (ground thread): Non-slip polyester (167dtex, 1800F) Warp thread (pattern thread): Polyester thread (167dtex, 48F) Weft: Polyester yarn (167dtex, 48F) Rubber thread: Polyurethane thread (570dtex) Covering thread: nylon thread (78dtex, 24F) <Comparative Example> Warp: Polyester yarn (167dtex, 48F) Weft: Polyester yarn (167dtex, 48F) Rubber thread: Polyurethane thread (570dtex) Covering thread: nylon thread (78dtex, 24F)

[0030] <Evaluation Test (Part 1: KES Surface Properties)> As the first evaluation test, the surface friction coefficient MIU, the variation of the surface friction coefficient MMD, and the surface roughness SMD were measured using the KES method. Measurements were performed using a Kato Tech KES-SE under conditions of SENS: STD, static friction load: 50 gf, and static roughness load: 10 gf. The friction element was 10 mm x 10 mm, and consisted of an array of piano wires with a diameter of 0.5 mm. The friction element was moved at a speed of 1 mm / sec over the front and back surfaces of the clothing bands according to the examples and comparative examples. The variation in the surface friction coefficient MMD can be calculated, for example, using equation (1) described in Japanese Patent No. 4471097. Figure 3 shows the test results for the example, and Figure 5(A) shows the test results for the comparative example.

[0031] <Evaluation test (part 2: static and dynamic friction)> In the second evaluation test, a static and dynamic friction test was conducted using a Tribomaster on simulated skin to measure the static friction coefficient μs (the force / load (g) required to generate friction, *maximum value from 0 to 1 mm), the dynamic friction coefficient μk (friction force / load (g) while friction is generated, *average value from 10 to 50 mm), and the standard deviation D (deviation) of the friction resistance force (gf). The measurement conditions are shown below, and the test results for the example are shown in Figure 4 and the test results for the comparative example are shown in Figure 5(B). Static and dynamic friction test (Tribomaster TL201Ts) Test piece: rubber width x 100mm Test speed: 10mm / min Load: 25g Travel distance: 50mm (one way only) Contact: Flat contact Friction target: Simulated skin (BioSkin)

[0032] Figure 6 summarizes the results of Evaluation Test 1 (KES surface characteristics) for Example 1, Example 2, and the control Comparative Example, and Figure 7 summarizes the results of Evaluation Test 2 (static and dynamic friction). As shown in Figures 6 and 7, in Examples 1 and 2, the surface friction coefficient MIU, the variation in the surface friction coefficient MMD, and the surface roughness SMD, as well as the static friction coefficient μs, the dynamic friction coefficient μk, and the standard deviation D of the frictional resistance force (gf), are all greater than those of the Comparative Example, on both the front (opposite side to the skin) and back (skin side). From these results, it is clear that the clothing bands of the Examples are less slippery on both the front and back than the clothing bands of the Comparative Example, preventing boxer shorts from slipping off the skin and preventing shirts worn outside the boxer shorts from rolling up. Note that a larger variation in the surface friction coefficient MMD generally tends to result in a rougher feel. Furthermore, the surface roughness SMD is rough enough to not impair comfort, and the clothing bands according to the Examples are less slippery on both the front and back than the clothing bands according to the Comparative Examples.Here, the standard deviation D of the frictional resistance force (gf) is larger for the Examples than for the Comparative Examples, and it is clear that the non-slip polyester is exposed to a degree that does not impair comfort, and therefore the clothing bands according to the Examples are less slippery on both the front and back than the clothing bands according to the Comparative Examples.

[0033] More specifically, the superiority of the clothing band according to the embodiment over the clothing band according to the comparative example will be confirmed numerically.

[0034] As shown in Figs. 3, 5(A) and 6, The surface friction coefficient MIU is the average value of the Examples (0.286 + 0.324 + 0.352 + 0.307) / 4 = 0.31725, while that of the Comparative Example is 0.275. Therefore, (0.31725 / 0.275) x 100 means that the Example is 115.36% of the Comparative Example, which is at least 10% higher. Regarding the variation in the surface friction coefficient MMD, the average value of the Examples is (0.0240 + 0.0269 + 0.0275 + 0.0216) / 4 = 0.0250, while that of the Comparative Example is 0.114. Therefore, (0.0250 / 0.0114) x 100 means that the Example is 219.30% of the Comparative Example, which is at least 200% higher. Regarding the surface roughness SMD, the average value for the Examples is (14.156 + 11.883 + 12.612 + 16.266) / 4 = 0.0250, while that for the Comparative Example is 9.056, so (0.0250 / 0.0114) x 100 means that the Example is 151.60% of the Comparative Example, which is at least 40% higher.

[0035] As described above, the total average values of the front (opposite side to the skin) and back (skin side) in the Examples are larger than those in the Comparative Examples for the coefficient of surface friction MIU, the variation in the coefficient of surface friction MMD, and the surface roughness SMD, and it can be seen that the front (opposite side to the skin) and back (skin side) in the Examples are sufficiently non-slip. Note that it is sufficient that at least one of the coefficient of surface friction MIU, the variation in the coefficient of surface friction MMD, and the surface roughness SMD of the clothing band according to the present invention is greater than that of the Comparative Examples formed with the same yarns and yarn type except that ultrafine polyester fiber yarn is not used.

[0036] Next, as shown in Figs. 4, 5(B) and 7, The static friction coefficient μs of the examples is (1.337 + 1.250 + 1.311 + 1.228) / 4 = 1.2815, while that of the comparative example is 0.941. Therefore, (1.2815 / 0.941) x 100 means that the example is 136.18% of the comparative example, which is at least 30% higher. The coefficient of dynamic friction μk is (0.777 + 0.725 + 0.706 + 0.797) / 4 = 0.75125 for the Examples and 0.588 for the Comparative Examples, so (0.75125 / 0.588) × 100 means that the coefficient of dynamic friction μk for the Examples is 127.78% of the Comparative Examples, which is at least 20% higher. The standard deviation D of the frictional resistance force (gf) is 1.024 for the comparative example while the average value for the examples is (1.794 + 1.740 + 1.637 + 1.862) / 4 = 1.75825, so (1.75825 / 1.024) x 100 means that the example is 171.70% of the comparative example, which is at least 60% higher.

[0037] As described above, the total average values of the front (opposite skin side) and back (skin side) in the Examples are larger than those in the Comparative Examples for the static friction coefficient μs, the dynamic friction coefficient μk, and the standard deviation D of the frictional resistance force (gf), and it can be seen that the front (opposite skin side) and back (skin side) in the Examples are also sufficiently slip-resistant. Note that it is sufficient that the clothing band according to the present invention has at least one of the static friction coefficient μs, the dynamic friction coefficient μk, and the standard deviation D of the frictional resistance force (gf) greater than that of the Comparative Examples formed with the same yarns and yarn type except that ultrafine polyester fiber yarn is not used.

[0038] In this way, in lower body clothing (one example being boxer shorts) that mainly covers the abdomen and buttocks, the lower body clothing easily follows the movement of the wearer's body (particularly the waist) in response to movements of the lower body, and is less likely to slip (fall down), preventing shirts and the like worn on the outside of this lower body clothing from rolling up and making the garment look unattractive.In addition, a clothing band with an aesthetic appearance and lower body clothing that uses this clothing band can be provided.

[0039] It should be noted that the embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims. [Industrial Applicability]
