Description

[Technical field]

[0001] The present invention relates to a multi-knitted garment that can be worn at least around the foot (the area from the ankle to the toes), such as socks (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 comprising an inner sock body consisting of a toe portion, a foot insertion portion, and a leg insertion portion, and an outer sock body consisting of the toe portion, the foot insertion portion, and the 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, a sock knitted body being knitted by applying pile to the inner sides of the toe portions, the foot insertion portion, and the leg insertion portion of each of the inner sock body and the outer sock body, and the inner sock body and the outer sock body being overlapped and the toe portion of the inner sock body being sewn to the toe portion of the outer sock body). This type of double sock has excellent heat retention and is often worn, especially when the temperature is low. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2010-138532 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when a person wearing the above-mentioned 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 is excellent in heat retention and that prevents the wearer's area of ​​the garment from becoming stuffy. [Means for solving the problem]

[0006] The multi-knitted garment 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. The bulky knitted fabric has a higher heat retention than the moisture-absorbing, quick-drying knitted fabric or a 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 a higher moisture-absorbing, quick-drying property than the region made of the bulky knitted fabric. The moisture-absorbing, quick-drying knitted fabric may or may not have breathability.

[0007] As described above, this multi-knitted wearing tool has not only heat retention but also water absorption and quick drying properties. Therefore, this multi-knitted wearing tool has excellent heat retention and can prevent the wearing part of the person wearing this multi-knitted wearing tool from becoming stuffy. In addition, when the bulky knitted fabric has a lower thermal conductivity than the water absorption and quick drying knitted fabric, the bulky knitted fabric can prevent or suppress the heat of the wearing part from being lost by heat conduction to floors, shoes, etc. that are lower than body temperature, and the cold of the floor or shoes from being transmitted to the feet, compared to the water absorption and quick drying knitted fabric. Even if the parts that the multi-knitted wearing tool directly contacts, such as floors or shoes, are cold, it can prevent the heat of the feet from being lost by heat conduction to floors, shoes, etc. that are lower than body temperature, and the cold of the floor or shoes from being transmitted to the feet.

[0008] The multi-knitted wearing device according to the second aspect of the present invention is the multi-knitted wearing device according to the first aspect, and the multi-knitted wearing device can be worn at least on the 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 wearing tool according to a third aspect of the present invention is the multi-knitted wearing tool according to the second aspect, in which the first knitted layer is located 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, the multi-knitted wearing device can prevent heat from being lost from the feet to the floor or shoes, which are colder than body temperature, through thermal conduction, and can prevent the coldness of the floor or shoes from being transmitted to the feet. Also, the multi-knitted wearing device can reduce the occurrence of discomfort in 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 a foot. The first knitted layer and the second knitted layer are provided only on the tip covering part. The tip covering part covers the tip part of the foot. The tip part of the foot here refers to the area of ​​the toes, and more specifically, the area in front of the MTP joint.

[0013] Incidentally, it is known that the tip of the foot is the most susceptible to getting cold, since it is the end of the foot. Generally, the tip of the shoe is provided with a space that is relatively larger than the tip of the foot, while the space between the shoe and the foot other than the tip is relatively small. Therefore, when the part other than the tip covering part of the multi-knitted wearing device is made of a single layer structure, the tip of the foot, which is particularly susceptible to getting cold, can be efficiently kept warm without making the foot cramped inside the shoe.

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

[0015] Therefore, even if the area where the multi-knitted wearing device comes into direct contact is cold, the multi-knitted wearing device 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 feet.

[0016] A multi-knitted wearing device according to a sixth aspect of the present invention is the multi-knitted wearing device according to the first aspect, further comprising at least one third knitted layer. The third knitted 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, and the air contained in the bulky region and the air above the low-bulk fabric region flow and diffuse. Therefore, this multi-knitted wearing device can flow and diffuse the air heated inside the wearing device when walking, etc., and can warm a relatively wide area of ​​the foot. In addition, this air flow and diffusion action promotes the gradual discharge of the air in the system with high humidity to the outside, making it difficult for the wearer's feet to become sweaty.

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

[0019] Therefore, even if the area with which the multi-knitted wearing device comes into direct contact, such as the floor or shoes, is cold, the multi-knitted wearing device 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 feet.

[0020] A multi-knitted wearing device according to an eighth aspect of the present invention is the multi-knitted wearing device according to the sixth or seventh aspect, in which the third knitted layer is knitted in a pseudo-pile knit pattern formed by interweaving (A) a flat 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 wearing device, it is possible to enjoy the heat insulating effect of the air layer, and even if the place where the multi-knitted wearing device comes into direct contact with, such as the floor or shoes, is cold, the cold is unlikely 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 can be worn at least on the foot. The third knitted layer constitutes a sole covering part that covers the bottom side of the foot.

[0023] Therefore, with this multi-knitted wearing device, it is possible to enjoy the heat insulating effect of the air layer, and even if the place where the multi-knitted wearing device comes into direct contact with, such as the floor or shoes, is cold, the cold is unlikely 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, in which 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 area is stepped on and its volume is reduced, and the air contained in the bulky area and the air above the low-bulk fabric area flow and diffuse. Therefore, this multi-knitted wearing device can flow and diffuse the air heated inside the wearing 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 difficult 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, in which the low loft region is adjacent to at least two high loft regions. In this case, both the high loft region and the low loft region may be strip-shaped, and the low loft region may be adjacent to the high loft region on both sides in the short direction.

[0027] Therefore, in this multi-knitted wearing device, the air flow and diffusion effect of the bulky regions with respect to the air above the low loft regions can be enhanced, and the air can be further flowed and diffused 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 part. The tip covering part covers the tip part of the foot. The tip part of the foot here refers to the area of ​​the toes, and more specifically, the area in front of the MTP joint.

[0029] Incidentally, it is known that the tip of the foot is the end of the foot and is therefore particularly susceptible to getting cold. Generally, the tip of the shoe is provided with a space that is relatively larger than the tip of the foot, while the space between the shoe and the foot other than the tip is relatively small. For this reason, when the part other than the tip covering part of the multi-knitted wearing device is made of a single structure, the tip of the foot, which is particularly susceptible to getting cold, can be efficiently kept warm without making the foot cramped inside the shoe, and the relatively wide area of ​​the tip of the foot can be warmed, making it difficult for the tip of the wearer's foot to get steamy.

[0030] A multi-knitted wearing device according to a thirteenth aspect of the present invention is the multi-knitted wearing device according to the twelfth aspect, in which 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 water-absorbing quick-drying yarn. In addition, 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 garment can efficiently absorb sweat generated from the feet and quickly dry the sweat, and can also efficiently and actively warm the wearer's feet by utilizing the moisture of evaporated sweat.

[0032] A multi-knitted wearing tool according to a fourteenth aspect of the present invention is the multi-knitted wearing tool 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 heat-generating properties. The moisture-absorbing heat-generating knitted fabric is knitted from a yarn having moisture-absorbing heat-generating properties. The water-absorbing quick-drying knitted fabric is knitted from a yarn including a moisture-absorbing quick-drying yarn. Either the second knitted layer or the fourth knitted layer is located as the innermost layer.

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

[0034] A multi-knitted wearing tool according to a fifteenth aspect of the present invention is the multi-knitted wearing tool according to any one of the first to fourteenth aspects, in which the moisture-absorbing, quick-drying knitted fabric is knitted from a front yarn and a back yarn. The front yarn includes a moisture-absorbing, quick-drying yarn or a moisture-absorbing, quick-drying yarn. When the front yarn includes a moisture-absorbing, quick-drying 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, quick-drying 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 actively warm the wearer's feet by utilizing the moisture of evaporated sweat.

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

[0037] Therefore, with this multi-knitted garment, not only can the effect of water 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, in which the bulky knitted fabric is a knitted fabric having a pile stitch. The pile part of the pile stitch faces another knitted fabric layer.

[0039] Therefore, with this multi-knitted wearing device, even if the place with which it comes into direct contact, such as the floor, is cold, the heat transfer area of ​​the cold can be reduced and the 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 multiple knitted harness according to the embodiment of the present invention> The multi-knitted wearing device according to the embodiment of the present invention is a wearing device with a multi-layer structure to be worn at least on the foot, such as socks (foot covers, socks, knee-high socks), stockings, tights, etc. The "foot" here refers to the part from the ankle to the toes. Examples of the multi-knitted wearing device according to the embodiment of the present invention include a double-knitted sock 100 shown in Figs. 1 to 3 and a double-knitted tights 200 shown in Fig. 10. The double-knitted sock 100 will be described in detail below as a first embodiment, and the double-knitted tights 200 will be described in detail as a second embodiment, and configurations that can be accepted in the present invention will 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 shape in side view as shown in Fig. 1, and is mainly composed of a foot covering part 110, a heel covering part 120, an Achilles tendon covering part 130, an ankle covering part 140, a lower leg covering part 150, and an opening part 160 as shown in Fig. 1 and Fig. 2. It can also be said that the double knit sock 100 is composed of an inner layer IL and an outer layer OL as shown in Fig. 3. These constituent parts and the two-layer structure will be described in detail below.

[0044] For ease of explanation, the up-down direction, the left-right direction, and the front-rear direction are defined in Figures 1 to 3. Below, 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 the lower leg covering part 150 or the opening part 160. If only the lower leg covering part 150 is not present, the opening part 160 will be provided above the Achilles tendon covering part 130 and the ankle covering part 140. If the multiple knitted wearing device is a stocking or tights, a thigh covering part will be provided instead of the opening part 160, and a panty part or the like will be added above the thigh covering part. The thigh part is the part from above the knee to the crotch, and the panty part is the part that covers part or all of the area from the crotch to the waist.

[0046] (1) Foot covering part The foot covering part 110 is a bag-shaped part for covering the area from the ankle to the toes, and as shown in Fig. 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 part The instep covering part 111 is a part that mainly covers the instep side of the foot, and is composed of an instep base part 111b and an instep tip part 111t as shown in FIG. 1. The instep base part 111b is a substantially rectangular part that mainly covers the instep of the foot. This instep base part 111b forms a cylindrical main covering part BP together with the bottom base part 112b (see FIG. 1). The instep tip part 111t is a substantially semidisk-shaped part that mainly covers the nail side of the toe, and extends forward from the tip of the instep base part 111b. This instep tip part 111t forms a bag-shaped tip covering part TP together with the bottom tip part 112t of the bottom covering part 112 (see FIG. 1).

[0048] The inner layer portion I11 (see FIG. 3) of the upper covering portion 111 is knitted by flat knitting, mesh knitting, tuck knitting, or the like. The inner layer portion I11 may or may not have breathability. A yarn having moisture-absorbing and quick-drying properties (hereinafter referred to as "moisture-absorbing and quick-drying yarn") is used as a yarn constituting the knitted fabric for knitting the inner layer portion I11. An example of the moisture-absorbing and quick-drying yarn is a polyester / polyurethane composite yarn such as LYCRA (registered trademark) fr. FX30 / 75. LYCRA (registered trademark) fr. FX30 / 75 also has deodorizing properties. A yarn other than moisture-absorbing and quick-drying yarn may be used as a yarn constituting the knitted fabric for knitting the inner layer portion I11. Examples of yarns other than water-absorbing quick-drying yarns include yarns having moisture absorbing and heat generating properties (hereinafter referred to as "moisture absorbing and heat generating yarns"), yarns having moisture absorbing and releasing properties (hereinafter referred to as "moisture absorbing and releasing yarns"), and yarns having deodorizing properties (hereinafter referred to as "deodorizing yarns"). Examples of moisture absorbing and heat generating yarns include polyester / rayon blended yarns such as Hight Heat-T and acrylic / rayon blended yarns such as WARM PLUS-R. Acrylic / rayon blended yarns usually show a temperature rise (moisture absorbing and heat generating properties) 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-structure knitted fabric made of a plain knit and an all-pile knit made of an acrylic / rayon blend yarn exhibits a heat retention rate of 47.2% in a heat retention test using a Thermo Lab II type testing machine (environmental conditions: 20°C, 65% RH), and a double-structure knitted fabric made of the same plain knit and border pile knit exhibits a heat retention rate of 46.8% in the same heat retention test. On the other hand, the yarn used to knit the knitted fabric of the other company's product only exhibits a temperature rise of at most 3.3°C under the same conditions. In addition, the bulky knitted fabric of the other company's product only exhibits a heat retention rate equal to or less than that in the same heat retention test. Examples of moisture-absorbing and releasing yarns include cotton yarn, wool yarn, polyester yarn, and acrylic yarn. In addition, when the inner layer portion I11 is knitted from a water-absorbing and quick-drying yarn and a yarn other than the water-absorbing and quick-drying yarn, one yarn may be used as the face yarn and the other yarn may be used as the back yarn. In such a case, it is preferable to use a water-absorbent, quick-drying yarn as the back yarn, and a yarn other than the water-absorbent, 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 upper covering portion 111 is knitted with full bulky knitting such as full pile knitting. This bulky knitting is a knitted fabric that not only forms an air layer that holds (contains) more air than flat knitting, mesh knitting, tuck knitting, etc., but also provides cushioning when the wearer walks, etc. In other words, this bulky knitting has higher heat retention than the above-mentioned inner layer portion I11, or lower thermal conductivity than the moisture-absorbing quick-drying knitted fabric. The bulky knitting only needs to have an air layer and high cushioning, and there are no particular limitations on the material or manufacturing method thereof. The bulky knitting can be formed, for example, by (i) changing the shape of the stitches, such as by forming the stitches in a loop-like pile knitting or pseudo-pile knitting, (ii) using bulky (fluffy) yarn, such as bulky yarn or untwisted yarn, that has been subjected to bulky processing, (iii) forming the entire outer layer portion O11 of the upper covering portion 111, and then performing post-treatment such as raising the fabric surface, or (iv) attaching a separate member, such as attaching a sponge-like member such as foamed urethane (see, for example, JP 2021-231665 A). 116509 (See, for example, Japanese Unexamined Patent Publication No. 2003-233615, etc.) As shown in FIG. 4, the outer layer portion O11 is knitted so that the bulky portion PB (for example, the pile portion) faces the inner layer side.

[0050] (1-2) Bottom Coverage 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. The bottom base part 112b forms a cylindrical main covering part BP together with the back base part 111b (see FIG. 1). The bottom tip part 112t is a substantially semidisk-shaped part that mainly covers the ventral side of the toe, and extends forward from the tip of the bottom base part 112b. The bottom tip part 112t forms a bag-shaped tip covering part TP together with the back tip part 111t of the back covering part 111 (see FIG. 1).

[0051] The inner layer region I12 of the bottom covering part 112 may be knitted with flat knitting, mesh knitting, tuck knitting, etc., like the inner layer region I11 of the upper covering part 111, or may be knitted with other knitting fabrics. In addition, this inner layer region I12 may be knitted with the same yarn as the yarn constituting the inner layer region I11 of the upper covering part 111, or may be knitted with a yarn different from the yarn constituting the inner layer region I11 of the upper covering part 111. However, it is preferable that the yarn knitting the inner layer region I12 of the bottom covering part 112 includes a moisture-absorbing quick-drying yarn.

[0052] On the other hand, the outer layer part O12 of the bottom side covering part 112 is knitted with partial bulky knitting such as border pile knitting. As shown in FIG. 6, this outer layer part O12 is knitted so that straight-band-shaped bulky regions RP and straight-band-shaped low-bulk regions RL are alternately arranged along the length direction Dl of the foot. The bulky 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 bulky parts, and can be knitted with, for example, flat knitting, mesh knitting, tuck knitting, and combinations thereof. Note that such partial bulky knitting can be knitted by alternately repeating bulky knitting and low-bulk knitting in the wale direction (see, for example, Utility Model Registration No. 3121397, etc.). In such a case, it is preferable to use thick yarn for bulky knitting and thin yarn for low-bulk knitting. As shown in FIG. 5, the outer layer portion O12 is knitted so that the bulky portion PB (for example, the pile portion) faces the inner layer side.

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

[0054] The inner layer portion I20 of the heel covering portion 120 (see FIG. 3) may be knitted with flat knitting, mesh knitting, tuck knitting, or the like, similar to the inner layer portion I11 of the upper covering portion 111, or may be knitted with other knitting fabrics. In addition, this inner layer portion I20 may be knitted with the same yarn as the yarn constituting the inner layer portion I11 of the upper covering portion 111, or may be knitted with a yarn different from the yarn constituting the inner layer portion I11 of the upper covering portion 111.

[0055] On the other hand, the outer layer region O20 of the heel covering part 120 may be knitted with bulky knitting such as pile knitting like the outer layer region O11 of the upper covering part 111, or may be knitted with other knitting fabrics. When the outer layer region O20 of the heel covering part 120 is knitted with bulky knitting, the bulky knitting may be knitted by the same method as the knitting method of the outer layer region O11 of the upper 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 upper 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 part 130 may be knitted with flat knitting, mesh knitting, tuck knitting, or the like, similar to the inner layer region I11 of the upper covering part 111, or may be knitted with other knitting fabrics. In addition, this inner layer region I30 may be knitted with the same yarn as the yarn constituting the inner layer region I11 of the upper covering part 111, or may be knitted with a yarn different from the yarn constituting the inner layer region I11 of the upper covering part 111.

[0058] On the other hand, the outer layer region O30 of the Achilles tendon covering part 130 may be knitted with bulky knitting such as pile knitting like the outer layer region O11 of the instep covering part 111, or may be knitted with other knitting fabrics. Furthermore, when the outer layer region O30 of the Achilles tendon covering part 130 is knitted with 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 Coverage 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 Fig. 1. The ankle covering part 140 is located below the lower leg covering part 150.

In addition to the above, the method of forming the panty part may also be a method of forming the panty part three-dimensionally by sandwiching a gusset between the tubular bodies. In any of the above methods, it is necessary to close the toes of the foot covering part 210 and to sew or fuse the end of the knitting so that it does not come undone.

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

[0115] <Characteristics 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, having the above-mentioned configuration, are excellent not only in heat retention but also in moisture absorption and quick drying. Therefore, the double knit tights 200 are excellent in 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 the double knit tights 200, the outer layer portion of the bottom covering part 212 in the foot covering part 210 is knitted with a pseudo-pile knit. Therefore, every time the wearer's foot steps on the bottom covering part 212, the air above the low volume area flows and diffuses due to the air flow and diffusion action of the high volume area. Therefore, the 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. In addition, this air flow and diffusion action encourages the air in the system, which has become humid, to be gradually discharged to the outside, making it difficult for the wearer's feet to become sweaty.

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

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

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

[0120] (D) Although the double knit tights 200 according to the second embodiment are entirely of a two-layer structure, only the tip of the leg covering part of the tights may be of a two-layer structure. In such a case, the part other than the tip may be of a single layer structure, and the part may be knitted in any knitted fabric (for example, flat knitting, mesh knitting, tuck knitting, full pile knitting, border pile knitting, zokki knitting, etc.). In addition, when the part other than the tip is knitted in zokki knitting, the panty part may be knitted in a knitted fabric other than zokki knitting. In such a case, it is preferable that the panty part is knitted in a pseudo-pile knitted fabric. A preferable example of such a pseudo-pile knitted fabric is, for example, a tuck-knit pseudo-pile knitted fabric (bulky knitted fabric) that is a cross-knit fabric (knitted fabric) of the above-mentioned core-sheath yarn and the above-mentioned crimped yarn. In such a case, 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 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 a range of 20 to 40, and the denier of the sheath yarn is preferably within a range of 10 to 20. In addition, as a knitting machine used for knitting the double knit pantyhose, for example, a 4-inch size knitting machine having a needle count of 360N to 400N is preferably used.

[0122] The above-described modified examples may be adopted individually or in appropriate combinations within the scope of the present invention.

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

[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 constituting the inner layer (skin side) 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 constituting the outer layer (outer part) 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 constituting the inner layer (skin side) 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 flat knit in a conventional manner, the outer layer area (outer area) of the back side tip part 111t was knitted with full pile knit in a conventional manner, and the outer layer area (outer area) of the sole side tip part 112t was knitted with border pile knit in a conventional manner. The border pile knit was knitted by combining pile knit and flat knit. The pile areas in the full pile knit and border pile knit were knitted so as to face the inner layer side.

[0126] (2) Measuring the internal environment of double-knit socks After attaching a temperature and humidity sensor to the skin at the base of the instep between the first and second toes of each foot, the above-mentioned double knit sock was worn on the right foot and a comparative thick sock was worn on the left foot. Next, sneakers were worn on each foot, and the temperature and humidity inside the socks were measured when worn for four hours under the following environment. As a result, the graph shown in Figure 13 was obtained. The comparative products were socks knitted with a single pile and the constituent yarns were polypropylene yarn, acrylic yarn, wool yarn, and other yarns.

[0127] Note Temperature: 9℃ (December average) for the first hour, then 15℃~20℃ Humidity: approx. 30% Location: Nara Prefecture business office

[0128] From the graph, it is clear that the double knitted socks according to this embodiment can not only keep the temperature inside the shoe higher than the comparative product, but also suppress the humidity inside the shoe. Therefore, these double knitted socks have excellent heat retention and can prevent the wearer's feet from becoming sweaty.
