Description

[Technical Field]

[0001] The present invention relates to a multi-knitted wearing device that can be worn at least around the foot (the area from the ankle to the toes), such as a sock (socks, knee-high socks, etc.), stockings, tights, etc. [Background technology]

[0002] In the past, a double sock has been proposed (see, for example, JP 2010-138532 A). This type of double sock is characterized by being formed by knitting a sock knit fabric comprising an inner sock body consisting of a toe portion, a foot insertion portion, and a leg insertion portion, and an outer sock body also consisting of a toe portion, a foot insertion portion, and a leg insertion portion, the leg insertion portion of the inner sock body being connected to the leg insertion portion of the outer sock body via a connecting yarn, and by applying terry to the inside surfaces of the toe portions, foot insertion portion, and leg insertion portions of the inner sock body and the outer sock body being overlapped and the toe portion of the inner sock body being sewn together (see, for example, JP 2010-138532 A). This type of double sock has excellent heat retention and is often worn, especially in cold weather. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-138532 Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a person wearing the above-described double socks engages in relatively vigorous exercise or enters a warm room, their feet tend to become sweaty.

[0005] An object of the present invention is to provide a multi-knitted garment that has excellent heat retention properties and prevents the wearer's body part from becoming stuffy. [Means for solving the problem]

[0006] A multi-knitted wearing device according to a first aspect of the present invention comprises at least one first knitted layer and at least one second knitted layer. The first knitted layer includes a region made of bulky knitted fabric. This bulky knitted fabric has higher heat retention than the moisture-absorbing, quick-drying knitted fabric or lower thermal conductivity than the moisture-absorbing, quick-drying knitted fabric. The second knitted layer includes a region made of moisture-absorbing, quick-drying knitted fabric. The moisture-absorbing, quick-drying knitted fabric has higher moisture-absorbing, quick-drying properties than the region made of bulky knitted fabric. This moisture-absorbing, quick-drying knitted fabric may or may not be breathable.

[0007] As described above, this multi-knitted wearing device has not only heat retention but also moisture-absorbing and quick-drying properties. Therefore, this multi-knitted wearing device has excellent heat retention properties and can prevent the area where the device is worn from becoming stuffy. Furthermore, when the bulky knitted fabric has a lower thermal conductivity than the moisture-absorbing and quick-drying knitted fabric, the bulky knitted fabric can, compared to the moisture-absorbing and quick-drying knitted fabric, prevent or suppress the loss of heat from the area where the device is worn to floors or shoes that are cooler than body temperature due to thermal conduction, or the transfer of cold from the floor or shoes to the feet. Even when the areas in direct contact with the multi-knitted wearing device, such as the floor or shoes, are cold, the bulky knitted fabric can prevent the loss of heat from the foot to floors or shoes that are cooler than body temperature due to thermal conduction, or the transfer of cold from the floor or shoes to the feet.

[0008] A multi-knitted wearing device according to a second aspect of the present invention is the multi-knitted wearing device according to the first aspect, and the multi-knitted wearing device is capable of being worn at least on a foot. The first knitted layer constitutes a sole covering part that covers the bottom side of the foot.

[0009] Therefore, this multi-knitted wearing tool can suppress the release of heat from the bottom side of the foot.

[0010] A multi-knitted attachment according to a third aspect of the present invention is the multi-knitted attachment according to the second aspect, wherein the first knitted fabric layer is positioned as the outermost layer of the bottom covering part.

[0011] Therefore, even if the floor, shoes, or other places with which the multi-knitted wearing device comes into direct contact are cold, this device can prevent heat from being lost from the feet to the floor or shoes, which are cooler than body temperature, through thermal conduction, and can prevent the coldness of the floor or shoes from being transmitted to the feet.In addition, this multi-knitted wearing device can reduce the likelihood of causing discomfort to the feet.

[0012] A multi-knitted wearing device according to a fourth aspect of the present invention is the multi-knitted wearing device according to any one of the first to third aspects, and can be worn at least on the foot. The first knitted layer and the second knitted layer are provided only on the tip covering portion. The tip covering portion covers the tip of the foot. Here, the tip of the foot refers to the area of ​​the toes, and more specifically, the area anterior to the MTP joint.

[0013] It is known that the toe region is the most susceptible to getting cold, since it is the distal end of the foot. Generally, the toe region of a shoe has a larger space than the toe region, while the space between the shoe and the foot other than the toe is relatively small. Therefore, if the multi-knitted wearing device has a single-layer structure for the portion other than the toe covering portion, it can efficiently insulate the toe region, which is particularly susceptible to getting cold, without making the foot feel cramped inside the shoe.

[0014] A multi-knitted attachment according to a fifth aspect of the present invention is the multi-knitted attachment according to any one of the first to fourth aspects, wherein the bulky portion of the bulky knitted fabric extends inward.

[0015] Therefore, even if the area where the multi-knitted attachment directly contacts is cold, the multi-knitted attachment can reduce the heat transfer area of ​​the cold and can enjoy the heat insulating effect of the air layer, thereby making it difficult for the cold to be transferred to the feet.

[0016] A multi-knitted attachment according to a sixth aspect of the present invention is the multi-knitted attachment according to the first aspect, further comprising at least one third knitted fabric layer. The third knitted fabric layer includes an area made of a partially bulky knitted fabric.

[0017] The partially bulky knitted fabric has a bulky region and a low-bulk region. Each time the partially bulky knitted fabric is stepped on, the bulky region is stepped on and its volume is reduced, causing the air contained in the bulky region and the air above the low-bulk fabric region to flow and diffuse. This allows the multi-knitted wearing device to circulate and diffuse heated air within the wearing device during walking, etc., and to warm a relatively large area of ​​the foot. Furthermore, this air flow and diffusion action encourages the gradual expulsion of humid air within the system, preventing the wearer's feet from becoming sweaty.

[0018] A multi-knitted attachment according to a seventh aspect of the present invention is the multi-knitted attachment according to the sixth aspect, wherein the bulky portion of the partially bulky knitted fabric extends inward.

[0019] Therefore, even if the area where the multi-knitted attachment comes into direct contact with the foot, such as the floor or shoes, is cold, the multi-knitted attachment can reduce the heat transfer area of ​​the cold and can enjoy the insulating effect of the air layer, thereby making it difficult for the cold to be transferred to the foot.

[0020] A multi-knitted attachment according to an eighth aspect of the present invention is the multi-knitted attachment according to the sixth or seventh aspect, wherein the third knitted layer is knitted in a pseudo-terry knit pattern by interweaving (A) a plain knit course made of core-sheath yarn having elasticity and bulkiness, in which a core yarn is covered with a sheath yarn, and (B) a tuck knit course made of crimped yarn having elasticity and bulkiness.

[0021] Therefore, with this multi-knitted attachment, it is possible to enjoy the heat insulating effect of the air layer, and even if the place where the multi-knitted attachment comes into direct contact with, such as the floor or shoes, is cold, the cold is less likely to be transmitted to the feet.

[0022] A multi-knitted wearing device according to a ninth aspect of the present invention is the multi-knitted wearing device according to any one of the sixth to eighth aspects, and is capable of being worn at least on a foot. The third knitted layer constitutes a sole covering part that covers the bottom side of the foot.

[0023] Therefore, with this multi-knitted attachment, it is possible to enjoy the heat insulating effect of the air layer, and even if the place where the multi-knitted attachment comes into direct contact with, such as the floor or shoes, is cold, the cold is less likely to be transmitted to the feet.

[0024] A multi-knitted wearing tool according to a tenth aspect of the present invention is the multi-knitted wearing tool according to any one of the sixth to ninth aspects, wherein the partially bulky knitted fabric includes a bulky region and a low-bulk region. The low-bulk region is less bulky than the bulky region.

[0025] Therefore, every time the partially bulky knitted fabric is stepped on, the bulky region is stepped on and its bulk decreases, causing the air contained in the bulky region and the air above the low-bulk fabric region to flow and diffuse. As a result, this multi-knitted wearing device can circulate and diffuse the heated air inside the device when walking, etc., and can warm a relatively wide area of ​​the foot. In addition, it promotes the gradual discharge of humid air inside the system, making it less likely for the wearer's feet to become sweaty.

[0026] A multi-knitted wearing tool according to an eleventh aspect of the present invention is the multi-knitted wearing tool according to the tenth aspect, wherein the low-bulk region is adjacent to at least two high-bulk regions. In this case, both the high-bulk region and the low-bulk region may be strip-shaped, and the low-bulk region may be adjacent to the high-bulk region on both sides in the short direction.

[0027] Therefore, in this multi-knitted wearing device, the bulky region can enhance the air flow and diffusion effect on the air above the low bulk region, allowing the air to flow and diffuse further within the system.

[0028] A multi-knitted wearing device according to a twelfth aspect of the present invention is the multi-knitted wearing device according to any one of the sixth to eleventh aspects, and can be worn at least on a foot. The first knitted layer, the second knitted layer, and the third knitted layer are provided only on the tip covering portion. The tip covering portion covers the tip of the foot. Here, the tip of the foot refers to the area of ​​the toes, and more specifically, the area anterior to the MTP joint.

[0029] It is known that the toes of the feet are the most susceptible to getting cold, since they are the extremities of the foot. Generally, the toes of shoes have a larger space than the toes, while the space between the shoe and the foot is relatively small in areas other than the toes. Therefore, if the multi-knitted wearing device has a single-layer structure for the areas other than the toe covering, it can efficiently insulate the toes, which are particularly susceptible to getting cold, without cramping the foot inside the shoe. It can also warm the relatively wide area of ​​the toes, preventing the toes of the wearer from getting sweaty.

[0030] A multi-knitted attachment according to a thirteenth aspect of the present invention is the multi-knitted attachment according to the twelfth aspect, wherein the first knitted layer is an interwoven fabric layer of (a) a sheath-core yarn having elasticity and bulkiness, in which a core yarn is covered with a sheath yarn, and (b) a crimped yarn having elasticity and bulkiness. The second knitted layer is an interwoven fabric layer of (a) a sheath-core yarn having elasticity and bulkiness, in which a core yarn is covered with a sheath yarn, and a moisture-absorbing, quick-drying yarn. Furthermore, the third knitted layer is an interwoven fabric layer of (a) a sheath-core yarn having elasticity and bulkiness, in which a core yarn is covered with a sheath yarn, and (b) a crimped yarn having elasticity and bulkiness.

[0031] Therefore, this multi-knitted wearing device can efficiently absorb sweat generated from the feet and quickly dry the sweat, and can also actively and efficiently warm the feet of the wearer by utilizing the moisture of evaporated sweat.

[0032] A multi-knitted wearing device according to a fourteenth aspect of the present invention is the multi-knitted wearing device according to any one of the first to thirteenth aspects, further comprising at least one fourth knitted layer. The fourth knitted layer includes an area made of a moisture-absorbing heat-generating knitted fabric having moisture-absorbing and heat-generating properties. The moisture-absorbing and heat-generating knitted fabric is knitted from a yarn having moisture-absorbing and heat-generating properties. The moisture-absorbing and quick-drying knitted fabric is knitted from a yarn including a moisture-absorbing and quick-drying yarn. Either the second knitted layer or the fourth knitted layer is located as the innermost layer.

[0033] Therefore, this multi-knitted wearing device can efficiently absorb sweat generated from the feet and quickly dry the sweat, and can also actively and efficiently warm the feet of the wearer by utilizing the moisture of evaporated sweat.

[0034] A multi-knitted attachment according to a 15th aspect of the present invention is the multi-knitted attachment according to any one of the first to fourteenth aspects, wherein the moisture-absorbing, quick-drying knitted fabric is knitted from a front yarn and a back yarn. The front yarn includes a moisture-absorbing, heat-generating yarn or a moisture-absorbing, quick-drying yarn. When the front yarn includes a moisture-absorbing, heat-generating yarn, the back yarn includes a moisture-absorbing, quick-drying yarn, and when the front yarn includes a moisture-absorbing, quick-drying yarn, the back yarn includes a moisture-absorbing, heat-generating yarn.

[0035] Therefore, this multi-knitted wearing device can absorb sweat generated from the feet and quickly dry the sweat using the same knitted fabric, and can also actively warm the wearer's feet by utilizing the moisture of evaporated sweat.

[0036] A multi-knitted attachment according to a sixteenth aspect of the present invention is the multi-knitted attachment according to any one of the first to fifteenth aspects, wherein the moisture-absorbing, quick-drying knitted fabric is a mixed knit fabric of moisture-absorbing, heat-generating yarn and moisture-absorbing, quick-drying yarn.

[0037] Therefore, with this multi-knitted wearing tool, not only can the effect of moisture absorption and quick drying be enjoyed, but also the effect of moisture absorption and heat generation can be enjoyed.

[0038] A multi-knitted wearing tool according to a seventeenth aspect of the present invention is the multi-knitted wearing tool according to any one of the first to sixteenth aspects, wherein the bulky knitted fabric is a knitted fabric having terry stitches, and the terry stitches face another knitted fabric layer.

[0039] Therefore, with this multi-knitted attachment, even if the place where the multi-knitted attachment comes into direct contact with, such as the floor, is cold, the heat transfer area of ​​the cold can be reduced and the heat insulating effect of the air layer can be enjoyed, thereby making it difficult for the cold to be transferred to the feet.

[0042] <Configuration of the multi-knitted harness according to the embodiment of the present invention> The multi-knit wearing device according to the embodiment of the present invention is a multi-layered wearing device worn on at least the foot, such as a sock (foot cover, sock, knee-high sock), stockings, tights, etc. The "foot" referred to here refers to the area from the ankle to the toes. Examples of the multi-knit wearing device according to the embodiment of the present invention include a double-knit sock 100 shown in Figs. 1 to 3 and double-knit tights 200 shown in Fig. 10. Below, the double-knit sock 100 will be described in detail as a first embodiment, and the double-knit tights 200 will be described in detail as a second embodiment, and configurations that can be used in the present invention will also be described.

[0043] -First embodiment- <Configuration of double knit sock according to the first embodiment of the present invention> The double knit sock 100 according to the first embodiment of the present invention is a sock with a two-layer structure that has a hook-like shape when viewed from the side as shown in Fig. 1, and is mainly composed of a foot covering portion 110, a heel covering portion 120, an Achilles tendon covering portion 130, an ankle covering portion 140, a lower leg covering portion 150, and an opening portion 160 as shown in Fig. 1 and Fig. 2. This double knit sock 100 can also be said to be composed of an inner layer IL and an outer layer OL as shown in Fig. 3. These constituent portions and the two-layer structure will be described in detail below.

[0044] For ease of explanation, the up-down direction, left-right direction, and front-rear direction are defined in Figures 1 to 3. Hereinafter, the configuration of the double knit sock 100 may be explained using these directions.

[0045] Incidentally, the double knit sock 100 does not necessarily have to have a lower leg covering portion 150 or an opening portion 160. If only the lower leg covering portion 150 is absent, the opening portion 160 will be provided above the Achilles tendon covering portion 130 and the ankle covering portion 140. If the multi-knit wearing device is a stocking or tights, a thigh covering portion will be provided instead of the opening portion 160, and a panty portion or the like will be added above the thigh covering portion. The thigh portion is the region from above the knee to below the crotch, and the panty portion is the region that covers part or all of the area from below the crotch to the waist.

[0046] (1) Foot covering The foot covering part 110 is a bag-shaped part for covering the area from the ankle to the toes, and as shown in Figure 1, is mainly composed of an instep covering part 111 and a sole covering part 112. These parts will be described in detail below.

[0047] (1-1) Back of the hand covering The instep covering portion 111 is a portion that mainly covers the instep side of the foot and is composed of an instep base portion 111b and an instep tip portion 111t as shown in FIG. 1. The instep base portion 111b is a substantially rectangular portion that mainly covers the instep of the foot. This instep base portion 111b, together with the sole base portion 112b, forms a tubular main covering portion BP (see FIG. 1). The instep tip portion 111t is a substantially semidisc-shaped portion that mainly covers the nail side of the toe and extends forward from the tip of the instep base portion 111b. This instep tip portion 111t, together with the sole tip portion 112t of the sole covering portion 112, forms a bag-shaped tip covering portion TP (see FIG. 1).

[0048] The inner layer region I11 of the back covering portion 111 (see FIG. 3 ) is knitted using plain knitting, mesh knitting, tuck knitting, or the like. The inner layer region I11 may or may not be breathable. The knitted fabric used to knit the inner layer region I11 is made of a moisture-wicking, quick-drying yarn (hereinafter referred to as a "moisture-wicking, quick-drying yarn"). Examples of moisture-wicking, quick-drying yarns include polyester / polyurethane composite yarns such as LYCRA® fr. FX30 / 75. LYCRA® fr. FX30 / 75 also has deodorizing properties. The knitted fabric used to knit the inner layer region I11 may be made of yarns other than moisture-wicking, quick-drying yarns. Examples of yarns other than moisture-absorbing and quick-drying yarns include moisture-absorbing and heat-generating yarns (hereinafter referred to as "moisture-absorbing and heat-generating yarns"), moisture-absorbing and desorbing yarns (hereinafter referred to as "moisture-absorbing and desorbing yarns"), and deodorizing yarns (hereinafter referred to as "deodorizing yarns"). Examples of moisture-absorbing and heat-generating yarns include polyester / rayon blend yarns such as Hight Heat-T and acrylic / rayon blend yarns such as WARM PLUS-R. Acrylic / rayon blend yarns typically exhibit a temperature rise (moisture-absorbing and heat-generating property) of 3.7°C when measured using moisture-absorbing and heat-generating method B (test room temperature 20±2°C, initial humidity 40%RH / humidified humidity 90%RH). In addition, a double-layered knitted fabric consisting of plain knitting and all-terry knitting made from an acrylic / rayon blend yarn exhibited a heat retention rate of 47.2% in a heat retention test using a Thermolab II testing machine (environmental conditions: 20°C, 65% RH), while a double-layered knitted fabric consisting of the same plain knitting and border terry knitting exhibited a heat retention rate of 46.8% in the same heat retention test. In contrast, yarns used to knit fabrics made by other manufacturers only showed a temperature rise of at most 3.3°C under the same conditions. Furthermore, bulky knitted fabrics made by other manufacturers only showed the same or lower heat retention rate in the same heat retention test. Examples of moisture-absorbing and releasing yarns include cotton yarn, wool yarn, polyester yarn, and acrylic yarn. Furthermore, when the inner layer portion I11 is knitted from a moisture-absorbing and quick-drying yarn and a yarn other than the moisture-absorbing and quick-drying yarn, one yarn may be used as the face yarn and the other yarn as the back yarn. In such a case, it is preferable to use a moisture-absorbing, quick-drying yarn as the back yarn and a yarn other than a moisture-absorbing, quick-drying yarn as the face yarn (for example, a moisture-absorbing, heat-generating yarn, a moisture-absorbing, moisture-releasing yarn, a deodorizing yarn, etc.).

[0049] On the other hand, the outer layer portion O11 of the back covering portion 111 is knitted with a full-body bulky knit, such as full-body terry knit. This bulky knit not only forms an air layer that holds (contains) more air than flat knit, mesh knit, tuck knit, etc., but also provides cushioning when the wearer walks. In other words, this bulky knit has higher heat retention than the inner layer portion I11 described above, and lower thermal conductivity than the moisture-absorbing, quick-drying knit. The bulky knit only needs to have an air layer and high cushioning, and there are no particular limitations on the material or manufacturing method used. Bulky knitting can be achieved, for example, by (i) changing the shape of the stitches, such as by forming loops in pile knitting or pseudo-pile knitting, (ii) using bulky yarn or untwisted yarn that has been subjected to bulky processing, or by performing post-treatment such as raising the surface of the fabric after forming the entire outer layer portion O11 of the back covering portion 111, or (iv) attaching a separate member, such as a sponge-like member such as foamed urethane (see, for example, Patent Publication No. 2021- 116509 (See, for example, Japanese Patent Publication No. 2003-102494, etc.) As shown in FIG. 4, the outer layer region O11 is knitted so that the bulky region PB (for example, pile region) faces the inner layer side.

[0050] (1-2) Bottom covering part The bottom covering part 112 is a part that mainly covers the bottom side of the foot and is composed of a bottom base part 112b and a bottom tip part 112t as shown in FIG. 1. The bottom base part 112b is a substantially rectangular part that mainly covers the bottom of the foot. This bottom base part 112b, together with the back base part 111b, forms a tubular main covering part BP (see FIG. 1). The bottom tip part 112t is a substantially semidisc-shaped part that mainly covers the ventral side of the toe and extends forward from the tip of the bottom base part 112b. This bottom tip part 112t, together with the back tip part 111t of the back covering part 111, forms a bag-shaped tip covering part TP (see FIG. 1).

[0051] The inner layer region I12 of the sole covering part 112 may be knitted using plain knitting, mesh knitting, tuck knitting, etc., similar to the inner layer region I11 of the upper covering part 111, or may be knitted using other knitting fabrics. Furthermore, this inner layer region I12 may be knitted using the same yarn as the yarn that forms the inner layer region I11 of the upper covering part 111, or may be knitted using a yarn that is different from the yarn that forms the inner layer region I11 of the upper covering part 111. However, it is preferable that the yarn used to knit the inner layer region I12 of the sole covering part 112 includes a moisture-absorbing and quick-drying yarn.

[0052] On the other hand, the outer layer region O12 of the bottom-side covering portion 112 is knitted using a partial bulky knitting technique such as border terry knitting. As shown in FIG. 6, this outer layer region O12 is knitted so that straight-band-shaped high-bulk regions RP and straight-band-shaped low-bulk regions RL are alternately arranged along the foot length direction D1. The high-bulk regions RP can be produced by the above-mentioned method for producing a bulky knitted fabric. On the other hand, the low-bulk regions RL are regions having a lower bulk than the high-bulk regions, and can be knitted using, for example, plain knitting, mesh knitting, tuck knitting, or a combination thereof. Note that such partial bulky knitting can be produced by alternately repeating high-bulk knitting and low-bulk knitting in the wale direction (see, for example, Utility Model Registration No. 3121397). In such cases, it is preferable to use thick yarn for the high-bulk knitting and thin yarn for the low-bulk knitting. As shown in FIG. 5, the outer layer region O12 is knitted so that the bulky region PB (for example, pile region) faces the inner layer side.

[0053] (2) Heel covering part The heel covering part 120 is a part for covering the heel, and extends rearward from the rear end of the foot covering part 110 as shown in FIG.

[0054] The inner layer region I20 of the heel covering part 120 (see FIG. 3) may be knitted using plain knitting, mesh knitting, tuck knitting, etc., similar to the inner layer region I11 of the upper covering part 111, or may be knitted using other knitting fabrics. Furthermore, this inner layer region I20 may be knitted using the same yarn as the yarn that constitutes the inner layer region I11 of the upper covering part 111, or may be knitted using a yarn that is different from the yarn that constitutes the inner layer region I11 of the upper covering part 111.

[0055] On the other hand, the outer layer region O20 of the heel covering part 120 may be knitted with a bulky knitting such as terry knitting, similar to the outer layer region O11 of the instep covering part 111, or may be knitted with another knitted fabric. Furthermore, when the outer layer region O20 of the heel covering part 120 is knitted with a bulky knitting, the bulky knitting may be knitted by the same method as the knitting method of the outer layer region O11 of the instep covering part 111, or the bulky knitting may be knitted by a method different from the knitting method of the outer layer region O11 of the instep covering part 111.

[0056] (3) Achilles tendon covering The Achilles tendon covering portion 130 is a portion for covering the Achilles tendon, and extends upward from the upper rear end of the heel covering portion 120 as shown in FIGS.

[0057] The inner layer region I30 of the Achilles tendon covering portion 130 may be knitted using plain knitting, mesh knitting, tuck knitting, or the like, similar to the inner layer region I11 of the back covering portion 111, or may be knitted using other knitting fabrics. Furthermore, this inner layer region I30 may be knitted using the same yarn as the yarn that forms the inner layer region I11 of the back covering portion 111, or may be knitted using a yarn that is different from the yarn that forms the inner layer region I11 of the back covering portion 111.

[0058] On the other hand, the outer layer region O30 of the Achilles tendon covering part 130 may be knitted with a bulky knitting such as terry knitting, similar to the outer layer region O11 of the instep covering part 111, or may be knitted with another knitted fabric. Furthermore, when the outer layer region O30 of the Achilles tendon covering part 130 is knitted with a bulky knitting, the bulky knitting may be knitted by the same method as the knitting method of the outer layer region O11 of the instep covering part 111, or the bulky knitting may be knitted by a method different from the knitting method of the outer layer region O11 of the instep covering part 111.

[0059] (4) Ankle covering part The ankle covering part 140 is a part for covering the ankle, and extends upward from the upper front end of the foot covering part 110 as shown in Figure 1. The ankle covering part 140 is located below the lower leg covering part 150.

[0060] The inner layer region I40 of the ankle covering part 140 may be knitted using plain knitting, mesh knitting, tuck knitting, etc., similar to the inner layer region I11 of the back covering part 111, or may be knitted using other knitting fabrics. Furthermore, this inner layer region I40 may be knitted using the same yarn as the yarn that forms the inner layer region I11 of the back covering part 111, or may be knitted using a yarn that is different from the yarn that forms the inner layer region I11 of the back covering part 111.

[0061] On the other hand, the outer layer region O40 of the ankle covering part 140 may be knitted with bulky knitting such as terry knitting, like the outer layer region O11 of the instep covering part 111, or may be knitted with other knitted fabrics.

[0069] <Features of the double knit sock according to the first embodiment of the present invention> The double knit sock 100 according to the first embodiment of the present invention has the above-described configuration, which not only provides excellent heat retention but also excellent moisture absorption and quick-drying properties. Therefore, the double knit sock 100 not only provides excellent heat retention, but also prevents the feet of the person wearing the double knit sock 100 from becoming sweaty.

[0070] Furthermore, in this double-knit sock 100, the outer layer region O12 of the bottom covering part 112 in the foot covering part 110 is knitted using partial bulky knitting. Therefore, every time the wearer's foot steps on the bottom covering part 112, the air above the low-bulk region RL flows and diffuses due to the air flow and diffusion action of the bulky region RP. Therefore, this double-knit sock 100 can flow and diffuse the air heated within the sock when walking, etc., and can warm a relatively wide area of ​​the foot. Furthermore, this air flow and diffusion action encourages the humid air inside the sock to be gradually expelled to the outside, making it less likely for the wearer's feet to become sweaty.

[0071] <Modification> (A) In the double knit sock 100 according to the first embodiment, the instep tip portion 111t and the bottom tip portion 112t form a pouch-shaped tip covering portion TP, but the instep tip portion and the bottom tip portion may also form a toe pouch portion for covering each or several toes of the foot.

In addition to the above, the method of forming the panty portion also includes a method of sandwiching a gusset between tubular bodies to form a three-dimensional panty portion. In any of the above methods, it is necessary to close the toes of the foot-covering portion 210 and secure the knitting ends by sewing or fusing them to prevent them from unraveling.

[0114] As a knitting machine used to knit the double knit tights 200, it is preferable to use, for example, a 4-inch knitting machine having a needle count of 320N to 360N.

[0115] <Features of the double knit tights according to the second embodiment of the present invention> The double knit tights 200 according to the second embodiment of the present invention have the above-mentioned configuration, and therefore not only have excellent heat retention but also excellent moisture absorption and quick-drying properties. Therefore, the double knit tights 200 have excellent heat retention and can prevent the feet and legs of the person wearing the double knit tights 200 from becoming stuffy.

[0116] In addition, in these double-knit tights 200, the outer layer portion of the bottom covering portion 212 in the foot covering portion 210 is knitted using a pseudo-terry knit. Therefore, every time the wearer's foot steps on the bottom covering portion 212, the air above the low-bulk region flows and diffuses due to the air flow and diffusion action of the high-bulk region. Therefore, these double-knit tights 200 can flow and diffuse the air heated inside the socks when walking, etc., and can warm a relatively wide area of ​​the foot. Furthermore, this air flow and diffusion action promotes the gradual discharge of humid air inside the system, making it less likely for the wearer's feet to become sweaty.

[0117] <Modification> (A) In the double knit tights 200 according to the second embodiment, the instep tip portion 211t and the bottom tip portion 212t form a pouch-shaped tip covering portion TP', but the instep tip portion and the bottom tip portion may also form a toe pouch portion for covering each toe or several toes of the foot.

[0118] (B) No. 2 In the embodiment, the double knit tights 200 according to the second embodiment are taken up to explain an example of a multiple knit wearing tool. However, the multiple knit wearing tool is not limited to the double knit tights 200 according to the second embodiment, and may be any multiple knitting tool having triple or more layers. tights may be.

[0119] (C) In the double knit tights 200 according to the second embodiment, the inner layer portion of the instep covering portion 211 of the foot covering portion 210 is formed from an interwoven fabric (knitted fabric) of the above-mentioned core-sheath yarn and moisture-absorbing, quick-drying yarn. However, if the inner layer portion of the bottom covering portion 212 is knitted from such yarn, the inner layer portion of the instep covering portion 211 may be formed from an interwoven fabric of moisture-absorbing, heat-generating yarn and moisture-absorbing, quick-drying yarn.

[0120] (D) Although the double knit tights 200 according to the second embodiment have a two-layer structure overall, only the tip portions of the leg-covering portions of the tights may have a two-layer structure. In such cases, the portions other than the tip portions may have a single-layer structure, and these portions may be knitted in any knitting pattern (for example, plain knitting, mesh knitting, tuck knitting, full terry knitting, border terry knitting, zigzag knitting, etc.). Furthermore, if the portions other than the tip portions are knitted in zigzag knitting, the panty portion may be knitted in a knitting pattern other than zigzag knitting. In such cases, it is preferable that the panty portion be knitted in a pseudo-terry knitting pattern. A preferred example of such a pseudo-terry knitting pattern is, for example, a terry knitted pseudo-terry knitting pattern (bulky knitting pattern) that is a mixed knit (knitted) fabric (fabric) of the above-mentioned core-sheath yarn and the above-mentioned crimped yarn. In such cases, the example in which the gore line GL of the modified example (M) of the first embodiment is branched into a Y shape may be applied.

[0121] (E) The technology applied to the double knit tights 200 according to the second embodiment may also be applied to double knit pantyhose. When a single covered yarn is used as the core-sheath yarn, the denier of the core yarn in the single covered yarn is preferably within the range of 20 to 40, and the denier of the sheath yarn is preferably within the range of 10 to 20. Furthermore, the knitting machine used to knit the double knit pantyhose is preferably, for example, a 4-inch knitting machine with a needle count of 360N to 400N.

[0122] The above-described modifications may be adopted individually or in appropriate combinations within a range that does not cause any contradictions.

[0123] The present invention will be described in more detail below with reference to examples. [Example]

[0124] (1) Manufacturing of double knit socks (1-1) Selection of thread Rayon acrylic yarn (60% rayon / 40% acrylic) is used as the surface yarn that constitutes the inner layer (skin side portion) other than the tip covering part TP, with deodorizing yarn used as the backing yarn. Rayon acrylic yarn (60% rayon / 40% acrylic) is used as the surface yarn that constitutes the outer layer (outer portion) of the tip covering part TP, with deodorizing yarn used as the backing yarn. High multi-polyester yarn (moisture-absorbing modified type) is used as the surface yarn that constitutes the inner layer (skin side portion) of the tip covering part TP, with deodorizing yarn used as the backing yarn.

[0125] (1-2) Organization The areas other than the tip covering part TP were knitted with a thin pile knit in a conventional manner (i.e., this area has a single layer structure). The inner layer area (skin side area) of the tip covering part TP was knitted entirely with plain knitting in a conventional manner, the outer layer area (outside area) of the back side tip part 111t was knitted with full terry knitting in a conventional manner, and the outer layer area (outside area) of the sole side tip part 112t was knitted with border terry knitting in a conventional manner. The border terry knitting was knitted by combining terry knitting and plain knitting. The pile areas in the full terry knitting and border terry knitting were knitted so that they faced the inner layer side.

[0126] (2) Measurement of the internal environment of double-knit socks A temperature and humidity sensor was attached to the skin at the base of the instep between the first and second toes of each foot, and then the double-knit socks described above were worn on the right foot and a thick comparison sock was worn on the left foot. Next, sneakers were worn on each foot, and the temperature and humidity inside the socks were measured after wearing them for four hours under the following conditions. The results were shown in the graph in Figure 13. The comparison socks were single-ply, all-terry knit socks made from polypropylene yarn, acrylic yarn, wool yarn, and other yarns.

[0127] Note Temperature: 9°C (average temperature in December) for the first hour, then 15°C-20°C Humidity: Approximately 30% Location: Nara Prefecture business office

[0128] The graph shows that the double knit socks of this example not only maintain a higher temperature inside the shoe than the comparative product, but also reduce the humidity inside the shoe. Therefore, these double knit socks have excellent heat retention and can prevent the wearer's feet from becoming sweaty.
