Description

Socks and its manufacturing method {SOCKS AND METHOD OF PRODUCING IT}

The present invention relates to a sock having a massage effect of imparting a moderate sense of stimulation to the core, and more particularly to a sock suitable for walking.

Conventionally, socks which impart a massage effect to the longest part of a foot by the uneven | corrugated peak formed by the knitted structure are proposed.

[Patent Document 1] Japanese Utility Model Registration No. 3076702

For example, Patent Document 1 discloses a sock having uneven peaks in which three uneven peaks are knitted three-dimensionally by tuck knitting or pearl knitting on the lining of a sock.

According to the conventional socks having the above-described configuration, when the socks are worn, the uneven peaks directly contact the surface of the sole, the weight is applied from above, and the pressing force acts to give a stimulus to obtain a constant massage effect.

However, the conventional socks having the above-described configuration, for example, stay on using the unevenness due to the knitting structure such as the jaw knitting or the pearl knitting, so that the convex portion formed can obtain an appropriate massage effect in terms of thickness and hardness. It was insufficient.

By the way, as shown in FIG.6 (b), the tribal arch H1 (calf arch) and the transverse arch H2 (horizontal arch) are formed in the heart of a person, and those two arches are at the time of walking grounding. Along with acting as a cushion for cushioning shock, it plays an important role in smoothly moving weight by distributing weight throughout the foot.

As shown in Fig. 6 (a), the medial arch H1 forms an arch over the first metatarsal G21 beyond the tibia, the columnar bone, and the medial lingual bone starting from the calcaneal tubercle G31. It consists of a palace and an outer arch that forms an arch over the fifth metatarsal G22 passing through the cubic bone starting from the calcaneal node G31. On the other hand, as shown in Fig. 6 (a), the crossbow arch (H2) has a long heart including an anterior arch formed from the first metatarsal bone G21 to the fifth metatarsal bone G22, and three tongue tongues. It consists of a main arch formed from the left side G32 to the right side G33.

Moreover, plantar tendon (H3) exists in the heart of a person, as shown to FIG. 6 (b). Plantar tendon (H3) is a strong tendon that extends from the calcaneus toward each toe, and plays an important role in the maintenance of the foot arch (H1). If the plantar tendon (H3) is normal, the function as a cushion to mitigate the impact of the ground and the foot by bending or straining the arch arch (H1) during walking or running. However, in the foot where the structure of the entire foot is hard and lacks the flexibility of the plantar tendon (H3), when the sole is grounded to the ground by running or the like, it is not possible to bend or tense, resulting in a strong tension in the plantar tendon (H3), As it is repeated, burden may be excessively applied to the tendon, causing inflammation (plantar tendonitis).

As described above, in general, a small insulator on the plantar tendon may be caused by a decrease in muscle strength, such as a calf or the like due to lack of exercise, or an overexposure of a foot due to sports. It is said that there are many cases of waiting for the pain to improve by devising to reduce the burden on the soles and massage movements of the soles because they heal naturally. For example, to absorb the shock at the time of putting a cushion material (heel cup) and arch support in a heel and the heart part, or to put a soft sole on the sole, and to reduce burden on plantar tendon, or to take off shoes In this state, massage is performed by putting the heart portion of the foot on the golf ball and rolling, or the toes are rolled back to press the heart portion with the fingers, or the sole massage is performed on the towel gather to stimulate the heart portion.

However, conventional socks in which irregularities are formed by knitted tissues are insufficient as a massage effect for a person who is concerned about inflammation of the plantar tendon. For this reason, it is considered to attach a member such as rubber or silicone to the inner surface of the sole of the socks separately, but there is a problem that the manufacturing cost is increased because a process of attaching rubber or silicone is required separately.

The problem to be solved by the present invention is that in the conventional socks, since the irregularities are formed by the knitting structure, the thickness or hardness of the convex portion is insufficient, and in the structure of attaching a member such as rubber or silicone to the inner surface of the sole of the sock, rubber, etc. There is a need for a separate attaching step, which increases the manufacturing cost.

In order to achieve the above object, the socks of the present invention,

A massage part comprising bulky yarn and thermoplastic fiber yarn is formed at a predetermined position of the socks, and the volume of the bulky yarn is increased by heat setting the massage part, and at least a portion of the thermoplastic fiber yarn is welded to the bulky yarn to make the massage part. The predetermined | prescribed thickness and hardness are given to the most main characteristic point.

(Effects of the Invention)

In the sock of the present invention having such a configuration, the volume of the bulky yarn is increased by heat-setting the massage unit comprising the bulky yarn and the thermoplastic fiber yarn, and at least a portion of the thermoplastic fiber yarn is welded to the bulky yarn to have a predetermined thickness and Since the hardness can be imparted, it is thicker than the convex portion of the conventional sock formed only of knitted tissue, and a rigid massage portion can be provided.

The present invention does not provide a process for attaching a member such as rubber or silicone to the inner surface of the sock, and provides a massage part in which bulky yarn and thermoplastic fiber yarn are knitted at a predetermined position of the sock for the purpose of obtaining a proper massage effect. The thermal setting of the massage part increases the volume of the bulky yarn, and at least a portion of the thermoplastic fiber yarn is welded to the bulky yarn to achieve a predetermined thickness and hardness.

Here, the "predetermined position" is a part which the user wants to perform a massage effect by receiving the pressurization from the massage part when putting on the socks of this invention, and exercising, and a massage part according to the objective, for example, It can be formed in the center of a sole part or in the position of a heel part. In addition, for example, in soccer, skiing, and snowboarding socks, a foot may be provided on the shin portion of the foot to provide a massage effect.

In this invention, it is more preferable to form the said massage part corresponding to the range containing at least one part of the plantar tendon of the long core part of a sole. As described above, as a means of alleviating the inflammation of the plantar tendon, massage is performed by placing the core portion of the foot on a golf ball and rolling, pressing the core portion with a finger by pressing the toe back, or performing a sole massage on the towel gather. This is because the present massage condition can be expected by forming the massage part of the sock of the present invention corresponding to the range along the plantar tendon of the long core of the sole.

In addition, in this invention, the shape of a massage part is not specifically limited, For example, you may make an external shape elliptical shape, and may form a massage part flat over the whole range, or may arrange | position so that a square massage part may be checkered. .

However, since the massage part is in contact with the sole of the foot, considering the air permeability, it is better to have a way out of the air. Therefore, as for the massage part, it is more preferable to arrange | position plurally the convex part of arbitrary shape at predetermined intervals. This is because an air escape path is formed between the convex portions. Moreover, it is more preferable that the massage part arrange | positions the convex part of narrow and elongate shape in a ridge shape at predetermined intervals. This is because, because of the local pressure by the weight can be expected more efficient massage effect. Moreover, although the space | interval of narrow convex part should just be designed suitably, it can be set as the range of 2 mm-8 mm, for example.

As described above, when the narrow and long convex portions are arranged in a ridge shape, the narrow and long convex portions are more preferably disposed in a direction orthogonal to the direction of the plantar tendon of the longest part of the sole. The plantar tendon is a tendon that extends in the direction of the foot, but when the narrow and long convex portions are arranged in a direction parallel to the foot, the plantar tendon is pressurized by the weight each time it walks, and the gap between the convex portions is retracted or the original restoration is repeated. This is because the effect of massaging the plantar tendon is improved.

In the present invention, the volume of the bulky yarn is increased by heat-setting the massage section in which the bulky yarn and the thermoplastic fiber yarn are knitted, and at least a portion of the thermoplastic fiber yarn is welded to the bulky yarn, so that the convex portion is formed only in the knitting structure such as chin knitting or pearl knitting. Compared with the conventional socks formed, the thickness can be reliably given to the massage part. The inventors have found that it is more preferable to knit the massage part in the knitting of the file, and to set the thickness in the range of 2.8 mm to 6.0 mm. In view of the characteristics of a conventional hosiery knitting machine, even if the bulky yarn is considered to have a bulky property, it is difficult to form a thickness exceeding 6.0 mm. For example, even if such a thickness can be formed, a decrease in production efficiency and quality This is because there is a high risk of causing. Moreover, it is because there exists a high possibility that sufficient massage effect may not be acquired when it is actually worn as it is thickness less than 2.8 mm. Therefore, the range of said 2.8mm-6.0mm is the most preferable range from a viewpoint of productivity, quality, and a massage effect.

By adopting the above constitution, in the socks of the present invention, the hardness of the massage portion can be reliably firm as compared with the conventional socks in which the convex portions are formed only of the knitting structure. In addition, according to the inventors' review, the amount of compression work of the massage part measured using a tester for measuring the compression characteristics of the fiber product under the conditions of the maximum compression load of 50 gf / cm 2 and the compression speed of 0.02 mm / sec is 0.4 to 0.8. It turns out that it is preferable that it is the range of gfcm / cm <2>. The smaller the numerical value, the higher the hardness of the test object. However, as the measured value is less than 0.4, the stimulus to the center of the heart becomes excessive, which impedes comfortable walking interlocking, while the measured value is higher than 6.0. The sensation of stimulation to the heart can no longer be felt, and the massage effect is also thinned accordingly. Therefore, the range of 0.4-0.8 gfcm / cm <2> is the range of the compression work amount (hardness) required in order to acquire the feeling of a stimulus to a core part by walking motion, and a massage effect according to it.

In this invention, it is more preferable to use the yarn which mixed the high shrinkage fiber and the low shrinkage fiber as a bulky yarn. This is because the high shrinkable fibers shrink when the thermal setting is performed, and the low shrinkable fibers are expanded in the loop to increase the volume so that the mass of the massage portion can be efficiently formed. As the bulky yarn, for example, wool can be used. However, in the case of wool, the cost is high and the effect of increasing the volume of the massage part when heat setting is relatively small. Therefore, in order to solve this problem, in the present invention, when using a yarn mixed with a high shrinkable fiber and a low shrinkable fiber as a bulky yarn, it is preferable to use acrylic fiber as the high shrinkable fiber and the low shrinkable fiber. Do.

As described above, when the yarn mixed with the high shrinkable acrylic fiber and the low shrinkable acrylic fiber is heat-set, the high shrinkable acrylic fiber shrinks, so that the low shrinkable acrylic fiber expands in a loop and becomes bulky. By using this action, the mass of the massage part can be efficiently formed.

In the present invention, as the thermoplastic fiber yarn, for example, a low-melting-point nylon yarn having high heat adhesiveness, a boucle yarn having a loop formed on the surface of the yarn, or the like can be used. However, the low-melting point nylon yarn has a problem in that it tends to be crushed after heat setting and also feels tingling. Further, in the case of buclesa, there is a problem that the weldability is low, it is difficult to knit. Then, in order to solve these problems, in this invention, it is preferable to use ethylene vinyl alcohol fiber yarn which is a composite fiber of fiber and polyester which consist of copolymer of ethylene and vinyl alcohol as a thermoplastic fiber yarn.

In the socks of the present invention, the knitting structure of the massage part is preferably a structure in which pile structures are arranged in a mottled shape. This is because by arranging the pile structure in such a mottled shape, the portions where the bulky yarn and the thermoplastic fiber yarn contact each other, the pile loops are easily welded on the thermoplastic fiber, and the hardness is also easily secured. This is because the air permeability of the cloth can be ensured even after curing by thermal setting.

Moreover, in the socks of this invention, it is more preferable that the ratio of bulky yarn and thermoplastic fiber yarn in a massage part is a range of 4: 1-6: 1 by weight ratio. This is because when bulky yarn is less than 4 times of the thermoplastic fiber yarn, the bulky action of the bulky yarn decreases gradually. In addition, when bulky yarn is knitted more than 6 times of the thermoplastic fiber yarn, the welding action by the thermoplastic fiber yarn is gradually lowered.

In addition, the following structure can be employ | adopted further in order for the socks of this invention to be a socks suitable for walking.

As described with reference to FIG. 6, the sole of the human foot includes the anterior arch formed over the first metatarsal bone G21 to the fifth metatarsal bone G22 and three tongues, and the left side G32 to the right side of the long core ( A crossbow arch (H2) consisting of a main arch formed over G33) is formed, but when a load is applied due to overuse of a foot due to sports or wearing high heels for a long time, the crossbow arch (H2) descends to impact by the arch of the sole of the foot. It is important to keep the shape of the transverse arch (H2) normal because absorption is not normally performed, and further, the plantar tendon causes inflammation. Therefore, in the sock of the present invention, it is more preferable to form the first fastening portion which fastens the long core portion and forms the periphery of the instep portion. It is because it can support so that a crossbow arch H2 may not fall by fastening a long core part and forming it around a instep part. In addition, a 1st fastening part can be formed by knitting a high elastic yarn, for example.

In the case of forming the first fastening portion as described above, it is further preferable that a second fastening portion is formed around the ankle portion, and the second fastening portion and the first fastening portion are connected at the bent portion on the upper surface side of the socks. Do. This is because by engaging the Achilles tendon in addition to the support of the crossbow arch (H2), the fatigue caused by walking for a long time is reduced, and the walking operation is stabilized by preventing shaking of the ankle part.

Further, for example, when connecting the first fastening portion and the second fastening portion knitted with high elastic yarn at the bent portion on the upper side of the socks, the flexibility of the bent portion is slightly impaired. Therefore, as mentioned above, when forming the 1st fastening part and the 2nd fastening part, and connecting it on the upper surface of a sock, it is more preferable that the said bending part should be a chin knitting. This is because a tendon is formed in the circumferential direction of the sock by the knitting of the jaw so that the angle of the bend (the angle formed by the legs and the instep of the socks) of the sock can be easily followed by the movement.

In the socks of the present invention, it is more preferable to form the annular first pile knitted portion at the inner side position of the socks so as to correspond to the big toe base portion while wearing the socks. Since the base portion of the big toe is a portion to which a force is applied when walking, the first pile knitting portion of the big toe absorbs the shock applied when walking and the base portion of the big toe slides inside the socks. It is desirable because it disappears and becomes easier to walk.

Further, in the socks of the present invention, it is more preferable to form a second pile knitting portion having a predetermined shape at the inner side position of the socks so as to correspond to the base portion from the middle toe to the toe in the state of wearing the socks. The base portion extending from the middle toe to the toe is also a portion to which a force is applied during the walking operation, but by forming the second pile knitting portion of a predetermined shape, the shock can be absorbed and the stability is improved.

In the socks of the present invention, it is more preferable that the inner side of the heel and the inner side of the toe of the heel are piled together, and the length of the heel of the heel is longer than the pile length of the toe. The heel part that is the most impacted at the time of landing at the time of the pile has a long file length to improve the shock absorption ability, and the toe is applied to the toe in the direction of the car with a short file length. In addition to securing the force, the impact on the toes when the vehicle is intended to mitigate.

As described above, when the first pile knitted portion and the second pile knitted portion are formed, and the inner side of the heel portion and the inner side of the toe portion are configured together with the pile piece, the first pile knitted portion and the It is more preferable that both of the pile lengths of the second pile knitting portion are shorter than the pile length of the heel portion and longer than the pile length of the toe portion. Thus, by making the pile length of the 1st pile knitting part and the 2nd pile knitting part into an intermediate length, the said effect (effect of shock absorption of a heel part, securing the in-vehicle force and relaxation of an impact) can be obtained preferably. Because there is.

In the socks of the present invention, it is more preferable to form a mesh knitted portion on the sole side of the gap portion between the toes. This is because the mesh portion of the gap between the toe, which is most likely to be wet, can be used for ventilation so that the foot can be prevented from getting wet.

Further, in the socks of the present invention, it is more preferable that the diameter of the leg portion of the socks is configured so that the diameter becomes thicker toward the opening portion. This is because the pressure of the opening can be reduced by being close to the shape of the calf of the person.

The manufacturing method of the socks of this invention is a method of manufacturing the socks of this invention, The massage part knitting process which knits a bulky yarn and a thermoplastic fiber yarn in the predetermined position of the core part of a socks, and the said massage part of 110 degreeC-130 degreeC And a heat setting step of applying a predetermined thickness and hardness to the massage part by welding at least a portion of the thermoplastic fiber yarn to the bulky yarn by thermally setting at a temperature for a predetermined time. The heat setting process is a method of manufacturing a sock, characterized in that it is combined with the heat setting process of the whole sock for controlling the shape of the sock at the same time. Moreover, in the manufacturing method of the socks of this invention, it is more preferable that the heat setting time of the said massage part in the said heat setting process shall be in the range for 1 to 30 second. It is because there exists a possibility that the action which gives predetermined | prescribed thickness and hardness to a massage part by heat setting may become in less than 1 second. In addition, in order to give a predetermined thickness and hardness to a massage part, it is enough within 30 second, and when heat setting more than 30 second, a fiber may deteriorate and damage a texture, and unnecessary time may be taken, and production efficiency may increase. Because it gets worse.

According to the method for manufacturing a sock of the present invention, the above-described heat setting process is combined with the heat setting process of the whole sock for adjusting the shape of the sock, the production efficiency is improved.

(Example)

EMBODIMENT OF THE INVENTION Hereinafter, the best form of the socks of this invention and its manufacturing method is demonstrated using FIGS. 1 is an explanatory view showing the sole side of the sock in the state of inverting the sock of the present invention for the left foot, FIG. 2 is an explanatory view of the massage part, (a) is a state before heat setting, and (b) is a heat setting 3 is an explanatory view showing the instep side of the sock in the state where the sock is inverted, FIG. 4 is a view showing the state where the sock is viewed from the side of the big toe, and FIG. The figure which looked at the state which looked at the sock side of a sock toe.

As shown in Fig. 1, the sock S of this embodiment is knitted using a stretch yarn by a sock circular knitting machine, and the sole portion A, the long core portion B, and the heel portion J are similar to the normal socks. ), The toe K is provided. The most characteristic constitution of the present invention is to form a massage part 1 in which bulky yarn and thermoplastic fiber yarn are knitted at a predetermined position of the sole part A of the sock S, and the massage part 1 is formed. The heat setting increases the volume of the bulky yarn and at least a portion of the thermoplastic fiber yarn is welded to the bulky yarn to impart a predetermined thickness and hardness to the massage part 1.

Here, a "predetermined position" is a site which thinks that it wants to perform a massage effect by receiving the pressure from the massage part 1 when putting on the socks S of this invention, for example, when walking, The massage part 1 may be formed in the position of the center part of the sole part A, or the heel part J according to the objective, for example.

In the sock S of this embodiment, as shown in FIG. 1, the massage part 1 is formed corresponding to the range along the plantar tendon of the long core part B of a sole in the state which wore the sock S. As shown in FIG. The plantar tendon is a strong tendon that extends from the calcaneus toward each toe, as shown in FIG. 6B. When the plantar tendon is inflamed, as described above, the present condition is that by placing a foot on a golf ball and rolling it, or rolling the toes back, pressing the heart portion with a finger or performing a sole massage on a towel gather, but the present invention As shown in FIG. 1, the massage part 1 of the socks S is formed in the range along the plantar tendon of the long core part B of the sole (the range enclosed by the dotted line in FIG. 1) to expect the same massage effect. Because it can.

Since the massage part 1 is formed by knitting a bulky yarn and a thermoplastic fiber yarn, the shape can be freely determined by programming in a sock knitting machine. For example, the massage part 1 may be formed flat in an oval shape over the whole range, and about 10-20 square massage parts 1 may be arrange | positioned so that it may become a checkered pattern. Moreover, you may arrange | position a some circular massage part 1 at random.

In the sock S of this embodiment, as shown in FIG. 1, the massage part 1 arrange | positions the convex part 2 of a narrow and elongate shape in a ridge shape at predetermined intervals. Since the massage part 1 is a part in contact with the sole of the foot, considering the air permeability, it is better to have a length of air escape. When the arrangement arrange | positioned in the shape of a ridge as shown in FIG. 1 forms a gap between the narrow and long convex parts 2, the length which an air escapes to a horizontal direction is formed by this clearance, and it is local by weight Since it is pressurized, a more efficient massage effect can be expected. In the socks S of the present embodiment, seven narrow and long convex portions 2 are formed, and the interval between the convex portions 2 is about 4 mm.

Moreover, in the socks S of this embodiment, as shown in FIG. 1, the narrow convex part 2 is arrange | positioned in the direction orthogonal to the direction of the plantar tendon of a sole. The plantar tendon is a tendon that extends in the direction of the foot of the foot, but when the narrow and long convex portions 2 are arranged in a direction parallel to the foot length (that is, the circumferential direction of the foot), the plantar tendon is pressurized by the weight every time it walks. This is because the effect of planting the plantar tendon is improved by repeating the motion of 2).

2: is explanatory drawing of a massage part, (a) has shown the state before heat setting, and (b) has shown the state after heat setting. In FIG. 2A, the bulky yarn does not have a large volume due to the heat setting transition, and the welding portion 1 has insufficient thickness and hardness because the welding with the thermoplastic fiber yarn is not completed. The present invention heat-sets the massage part 1 in which the bulky yarn and the thermoplastic fiber yarn are knitted, so that the bulky yarn becomes bulky and at least a part of the thermoplastic fiber yarn is bulky yarn as shown in FIG. Compared with the conventional socks which were welded and formed convex portions only by knitting structures such as jaw knitting and pearl knitting, there is a feature that the thickness and hardness can be reliably imparted to the massage portion 1.

In the sock S of this embodiment, the knitting structure of the massage part 1 is a structure which arrange | positioned the pile structure in the mottled shape. This is because by arranging the pile structure in a mottled shape, the portions where the bulky yarn and the thermoplastic fiber yarn contact each other, the pile loops are easily welded by the thermoplastic fibers, and the hardness is also easily secured. This is because the air permeability of the cloth can be ensured even after curing by heat setting.

In the socks S of this embodiment, the thickness of the massage part 1 is 4.2 mm. In addition, about the compression work amount of the massage part 1, as demonstrated below, the value measured on the conditions of the upper limit compressive load 50gf / cm <2> and the compression rate 0.02mm / sec using the tester which measures the compression characteristic of a textile product. The range is 0.4 to 0.8 gfcm / cm 2.

The test machine used in the present Example is a measuring device which presses cloth from above, and sets the upper limit compressive load and the compression speed, respectively, and measures the hardness of the cloth. The compression characteristics test was performed on the massage part 1 of the socks S of this embodiment and the normal socks (comparative example) which used cotton blend spinning in the same knitted structure as the embodiment of this invention, and the hardness of each cloth ( The compression work amount gf cm / cm 2) was measured. The test method and test conditions were as follows, and the result was as showing in Table 1.

<Test method>

1) Cut the test cloth into 10cm × 10cm and set it to the measuring instrument.

2) Five parts of the same knitted fabric were measured arbitrarily in the test cloth, and the average value was computed.

<Test conditions>

Measuring instrument: KES-FB3 compression tester

Conditions: upper limit compressive load 50gf / cm 2, compression rate 0.02mm / sec

The smaller the numerical value of the compression work amount gfcm / cm 2, the harder the test cloth was. However, the embodiment of the present invention was confirmed to have twice the hardness of conventional products using conventional materials in that it is half the number of the comparative example. It became. In addition, as a result of various examinations by changing the ratio of bulky yarn and thermoplastic fiber yarn or the like, in the above test method, when the hardness of the massage part 1 is configured to be in the range of 0.4 to 0.8 gfcm / cm 2, an appropriate massage effect can be obtained. Could know.

In the socks S of the present embodiment, moderate hardness is obtained by setting the ratio of the bulky yarn and the thermoplastic fiber yarn in the massage part 1 to a weight ratio of 5: 1. In this invention, it is thought that it is preferable to make ratio of a bulky yarn and a thermoplastic fiber yarn be 4: 1-6: 1.

In the sock S of this embodiment, as a bulky yarn, a yarn in which high-shrink acrylic fibers and low-shrink acrylic fibers are mixed is used. When the bulky acrylic yarn is thermally set, the highly shrinkable acrylic fibers are shrunk, so the low-shrinkable acrylic fibers are expanded in a loop and bulky. The present invention uses this action to form a large volume of the massage part (1).

In the present invention, as the thermoplastic fiber yarn, for example, a low melting point nylon yarn having high heat adhesiveness, a buclesa having a loop formed on the yarn surface, or the like can be used. Some low-melting-point nylon yarns with high heat adhesiveness are commercially available under the name of Erda (registered trademark), for example. Erda (registered trademark) has a low melting point of 110 to 120 ° C and high heat adhesiveness. In addition, various kinds of vulcles which knitted crimp-shaped decorative yarns are commercially available.

However, in the case of low-melting point nylon yarn, there is a problem in that it is easy to be crushed after the heat setting and feels tinged, and in the case of buclesa, there is a problem that it is difficult to knit due to low weldability. Therefore, in the socks (S) of the present embodiment, the above problems are avoided by using ethylene vinyl alcohol fiber yarn which is a composite fiber of polyester and fiber composed of a copolymer of ethylene and vinyl alcohol as thermoplastic fiber yarn.

3 is an explanatory view showing the instep side of the sock S in the state where the sock S of the present embodiment is turned over. The sock S of this embodiment is provided with the instep C, the ankle D, the leg L, and the opening M similarly to the normal sock.

The sock S of this embodiment forms the 1st fastening part 3 which fastens the long core part B, and forms the circumference | surroundings over the instep part C. As shown in FIG. When a load is applied to sports such as marathon, basketball, soccer, etc., or wearing leather shoes or high heels for a long time, the crossbow goes down and shock absorption by the arch of the sole is not normally performed. Although it is known that the tendon causes inflammation, it is possible to support the crossbow arch so that the crossbow does not fall by forming the first fastening portion 3. Moreover, the 1st fastening part 3 is formed by knitting high elastic yarn on the knitted fabric of the socks S. Moreover, as shown in FIG.

4 is a view showing the state of the socks (S) of the present embodiment viewed from the side of the big toe, Figure 5 is a view showing the state of the socks viewed from the side of the little toe. E represents the bend of the sock S at which the ankle D and the leg L intersect.

In the sock S of the present embodiment, as shown in FIGS. 3 to 5, the second fastening portion 4 that forms the first fastening portion 3 and is formed around the ankle portion D is further formed. Forming. The 2nd fastening part 4 also makes high fastening force by knitting high elastic yarn. In addition, the first fastening portion 3 and the second fastening portion 4 are connected at the position of the bent portion E of the upper surface of the socks (S). In this way, the Achilles tendon is concluded in addition to the support of the crossbow, thereby reducing the labor of long walks. In addition, since the part of the ankle does not shake during walking, the walking operation is stabilized and comfortable walking can be performed.

As described above, when the first fastening portion 3 and the second fastening portion 4 in which high elastic yarns are knitted are connected at the bent portion E of the upper surface of the socks S, the flexibility of the bent portion E is slightly damaged. Therefore, in the socks S of the present embodiment, the bent portion E is the jaw knitting. In this way, since several tendons are formed in the circumferential direction of the socks S, the angle of the bend portion E (the angle formed by the leg portion L and the instep portion C of the socks) becomes wider or narrower according to walking. This is because it becomes easy to follow.

As shown in Fig. 1 and Fig. 4, the socks S of the present embodiment have an annular first pile knitting portion at the inner side position of the socks S corresponding to the base portion of the big toe in the state where the socks S are worn. (5) is formed. It is because the base part of a big toe is a part to which a force is applied at the time of walking, and can form the annular 1st pile knitting part 5, and can absorb the impact applied at the time of walking. Moreover, since the curved surface of the base part of a big toe is accommodated in the center part of the annular pile knitting part 5, it also has the effect that it does not slip inside the sock S, and it becomes easy to walk.

In addition, the sock S of this embodiment is a shape as shown to FIG. 1 and FIG. 5 in the position of the inner side of the sock S corresponding to the base part from the middle toe to the little toe in the state which wore the sock S. FIG. The 2nd pile knitting part 6 of this is formed. Since the base portion extending from the middle toe to the little toe is a portion to which a force is applied during the walking operation, similarly to the first pile knitting portion 5, it aims at securing shock absorption and in-vehicle force.

In FIG. 1, the medial side of the heel J and the medial side of the toe K are pile knitted. And in the sock S of this embodiment, the pile length of the heel part J is made longer than the pile length of the toe part K. As shown in FIG.
