Description

  The present invention relates to socks, and particularly to socks that are good for health.

  In order to fit the socks of conventional socks, in addition to knitting yarn (the main yarn in socks), covered yarn in which nylon processed yarn is wrapped around polyurethane elastic yarn as the back yarn (covered yarn is the core yarn) In many cases, a filament yarn or a spun yarn is wound around the yarn. In the case of using such a covered yarn, the knitting yarn appears on the outer surface of the sock, and the covered yarn serving as the back yarn appears on the inner surface of the sock. Accordingly, in the case of using such a covered yarn, the nylon-processed yarn that is a covering yarn in the covered yarn appears on the entire inner surface.

  On the other hand, silk thread is often used as a material for health-friendly socks. However, in the case of normal socks with a fit, covered yarn is used as the back thread as described above, so even if silk yarn is used for the knitting yarn, the silk thread will be on the outside and it will not touch the foot directly. It is a synthetic fiber such as nylon and cannot exhibit the hygroscopic properties of silk thread.

  In order to improve such problems, Utility Model Registration No. 3015174 (Patent Document 1) discloses a synthetic fiber that is relatively resistant to friction, with a surface yarn made of natural fibers such as silk that is relatively resistant to friction. Is knitted with the yarn as a back yarn to form a sock made of fibers whose surface is weak against friction and whose back is strong against friction. After that, it has been proposed to turn this over to make the fiber vulnerable to friction the back side.

  Also, utility model registration No. 3055454 (Patent Document 2) discloses socks for drying prevention. This sock is a sock constructed of a double structure of an inner layer and an outer layer, and the inner layer socks and the outer layer socks are connected to each other at the mouth portion, and the inner socks and the outer socks are continuous. Are organized. Then, after knitting, the shoe lower part that is the inner layer is pushed into the shoe lower part that is the outer layer to form a double structure. The lower part of the shoe, which is the inner layer, uses hygroscopic natural fibers such as silk thread.

As a similar sock, utility model registration No. 30686614 (patent document 3) discloses a warm sock. Similar to the above-mentioned Patent Document 2, this warm sock has a double structure consisting of an inner sock and an outer sock. The inner socks and the outer socks are continuously knitted in a continuous state at the mouth. Then, knitting the inner layer socks using silk yarn having a heat retaining effect, and preferably knitting using yarn made of synthetic fibers blended with gingeron etc. contained in shoga etc. as yarn for knitting the inner layer socks Is disclosed. Since it has a double structure in this way, it is said that heat retention is good.

  In the socks disclosed in Patent Document 1 described above, after knitting with the front yarn and the back yarn, the socks are turned upside down, so the outer stitch is not a normal front stitch but a back stitch. Therefore, it looks unpleasant, it seems that the socks are worn wrongly, and the wearer appears to be a gentle person. In addition, when using a covered yarn with a polyurethane elastic yarn as a back yarn and a core yarn covered with a nylon processed yarn as a back yarn to improve the fit, the covered yarn appears on the outer surface of the sock by turning it over. It will be. However, such covered yarns are not strong in polyurethane elastic yarn, so the outside is more rubbed than the inside of the socks, and it is rubbed with hard things etc., so it will break faster than usual. Arise.

  Moreover, in the sock having a double structure as disclosed in Patent Document 2 and Patent Document 3, the heat retention effect and the effect that the heel does not become lumpy can be obtained, but the sock is thick because of the double structure. There is a problem of becoming. There is also a problem that when the socks are thick, the shoes that are usually worn cannot be worn. In addition, there is a problem that the inner layer and the outer layer are separated from each other due to the double structure, and the appearance is worse. In winter, such socks may be used, but they are not suitable for summer use.

  The present invention solves the conventional problems as described above, and provides a sock that is healthy and is not as thick as a conventional sock.

In the present invention, at least the sole and the instep of a sock are knitted using a knitting yarn as a front yarn, a covered yarn as a back yarn, and the covered yarn has a polyurethane elastic yarn as a core yarn and bamboo fiber as a main yarn. The above-mentioned object is achieved by a sock characterized in that the thread to be wound is wound around the core thread as a covering thread, and the thread mainly composed of the bamboo fiber appears on the inner surface of the sole and instep of the sock. Achieve.
.

  Further, in the present invention, at least the sole part and the instep part of the socks are knitted with the knitting yarn as the front yarn, the core span yarn as the back yarn, and the core span yarn has the polyurethane elastic yarn as the core yarn, and bamboo fiber The short fibers mainly composed of bamboo fibers appear on the inner surfaces of the soles and insteps of the socks. The above object is achieved by socks.

  In the present invention, the front yarn and the back yarn are preferably knitted by a spliced yarn.

  In the present invention, a knitting yarn is used as a surface yarn, and a covered yarn (that is, a yarn in which a filament yarn or a spun yarn is wound around a core yarn) or a core span yarn (that is, another fiber is wound around the core yarn into a sheath shape in the spinning process). At least the sole part and the instep part of the sock are knitted using the wound thread) as the back thread. According to the present invention, the covered yarn uses a polyurethane elastic yarn as a core yarn, and a coated yarn in which a yarn mainly composed of bamboo fiber is wound around the core yarn. In the case of the core spun yarn, a polyurethane elastic yarn is used as a core yarn, and short fibers mainly made of bamboo fibers are wound around the sheath around the polyurethane elastic yarn. In the sock of the present invention, the yarn covering the core yarn in the back yarn and the fiber covering the core yarn appear on the inner surface of the sock. It is mainly made of fiber, and can exhibit properties such as antibacterial action of bamboo fiber.

  Therefore, according to the present invention, it is possible to suppress the propagation of various germs by the natural antibacterial action of the bamboo fiber, so that the sock can be prevented from becoming odorous.

  In addition, the applicant of the present invention diligently researched and measured the skin surface temperature by thermography while wearing bamboo fiber products, and measured changes in blood flow velocity and blood flow with a laser Doppler blood flow meter. When the skin touches the bamboo fiber, blood circulation improved and the skin temperature increased. Wearing the socks of the present invention improved blood circulation and warmed the feet. People with cold symptoms feel painful because their toes get cold, but the socks of the present invention improve the blood circulation of the feet when worn, so are particularly suitable for people with cold symptoms. In addition, the sock of the present invention improves blood circulation when worn, so it feels warm even in winter. Bamboo fiber is also hygroscopic, so the socks of the present invention are very suitable for summer. In addition, since bamboo fiber does not generate static electricity, there is no need to feel discomfort due to static electricity when putting on or taking off socks.

  Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings. FIG. 1 is a plan view of an embodiment of a sock according to the present invention, and FIG. 2 is a knitting structure diagram of a flat knitting showing an embodiment of a knitting method.

  FIG. 1 shows a sock 10 as an embodiment of a sock of the present invention. The socks of the present invention include not only short socks and high socks, but also those having a pants portion, such as tights, if the knitting yarn and the back yarn are used to knit at least the instep and the sole. It is a waste.

  In the present invention, the sock knitting method is not particularly limited, but usually the toe portion 16, the sole portion 15 and the heel portion 14 as shown in FIG. The leg portion 12 is often knitted from a flat knitting, a mesh knitting, a rib knitting, or a combination thereof. In general, the mouth portion 11 has many ribs and rubber yarns are often used.

  In the present invention, at least the sole portion 15 and the instep portion 13 are knitted using the knitting yarn (surface yarn) 1 and the back yarn 2 made of the covered yarn or the core spun yarn. Similarly, other parts of the socks (toe part 16, leg part 12, heel part 14 and wear mouth part 11) are knitted using a knitting yarn (front yarn) 1 and a back yarn 2 made of covered yarn or core spun yarn. Alternatively, another yarn may be added for reinforcement or the yarn may be changed. Further, a rubber thread may be inserted into the wearing mouth portion 11.

  The knitting yarn 1 is a main yarn when knitting socks, and becomes the front yarn 1 appearing on the front side of the socks. The material can be synthetic fiber yarn (nylon, polyester yarn, etc.), cotton yarn, cotton acrylic blend yarn, wool yarn, hair acrylic blend yarn, silk acrylic blend yarn, etc. It is preferable to use yarns mainly composed of bamboo fibers such as yarns made from bamboo and blended yarns of bamboo cotton.

  In the present invention, the covered yarn or the core spun yarn is knitted together with the knitting yarn 1 as the back yarn 2. The back yarn 2 in the present invention is different from the covered yarn used in conventional socks, and the yarn covering the polyurethane elastic yarn, which is the core yarn, is not a synthetic yarn but a bamboo fiber. The thread to be used is used. The yarn mainly composed of bamboo fiber is a spun yarn containing more than 50% bamboo fiber, preferably a spun yarn containing bamboo fiber, preferably 60% or more, more preferably 70% or more. Good. The fiber blended with bamboo fiber is preferably natural fiber such as cotton and hemp, but may be blended with synthetic fiber such as acrylic fiber to form a yarn. Bamboo fibers with 65 to 85% and cotton fibers with 35 to 15% are preferable because they exhibit the properties of bamboo fibers and provide strength with cotton fibers, no static electricity, and hygroscopicity.

  The covered yarn in the present invention may be a single covered yarn in which one yarn is wound around a polyurethane elastic yarn whose main yarn is bamboo fiber, or a double covered yarn that is wound twice by S twist and Z twist. Yarn may be used. The covered yarn of the present invention is manufactured by applying a polyurethane elastic yarn, which becomes a core yarn at the time of covering, to a draft of about 3 to 5 times and winding a yarn mainly composed of bamboo fiber around it.

  In addition, the core spun yarn of the present invention supplies polyurethane elastic yarn in a spinning process (during spinning) for making short fibers mainly made of bamboo fibers into yarns. The yarn is made while covering the polyurethane elastic yarn. The short fiber mainly composed of bamboo fiber contains more than 50% bamboo fiber, preferably 60% or more, more preferably 70% or more bamboo fiber. What consists only of bamboo fiber may be sufficient. The fiber blended with bamboo fiber is preferably natural fiber such as cotton and hemp, but may be blended with synthetic fiber such as acrylic fiber. Bamboo fibers with 65 to 85% and cotton fibers with 35 to 15% are preferred because they exhibit the properties of bamboo fibers and strength can be obtained with cotton fibers.

  In the present invention, as described above, the knitting method is not particularly limited. However, as shown in FIG. 2, it is preferable to perform knitting with a spliced yarn knitting the front yarn 1 and the back yarn 2 simultaneously. When knitting with a spliced yarn, the front yarn 1 appears on the outer surface of the sock and the back yarn 2 appears on the entire inner surface of the sock. Therefore, in the present invention, a covered yarn using a yarn mainly made of bamboo as a covering yarn or a core spun yarn in which a short fiber mainly made of bamboo is coated around a polyurethane elastic yarn is used as the back yarn 2. By doing in this way, the bamboo fiber which mainly consists of bamboo appears on the inner surface of the sock, so that the characteristics of the bamboo fiber can be utilized.

  The sole portion 15 is knitted by a flat knitting by a spliced yarn knitting as shown in FIG. 2, but the instep portion 13 may be a mesh knitting or a rib knitting instead of a flat knitting. Also in that case, it is preferable to use a spliced yarn for knitting the front yarn 1 and the back yarn 2 of the present invention simultaneously. Further, it is preferable that the other portions (the toe portion 16, the leg portion 12, the heel portion 14, and the wear mouth portion 11) are spliced yarns using the back yarn 2 of the present invention.

  As the surface yarn, 40-count double yarn was used as a spun yarn composed of 70% bamboo fiber and 30% cotton. A covered yarn having a yarn mainly composed of bamboo fiber as a covering yarn was used as a back yarn. This covered yarn is a spun yarn in which polyurethane elastic yarn with a thickness of 40 denier is used as the core yarn, blended with 70% bamboo and 30% cotton. What was wrapped around the core yarn with a cover was used. In the finished covered yarn, a yarn mainly composed of 3 m bamboo fiber was wound around a 1 m polyurethane elastic yarn. Using such front and back yarns, the leg part 12, the instep part 13, the heel part 14, the sole part 15 and the toe part 16 are all made into a flat knitting with a splicing knitting with a front yarn and a back yarn. The portion 11 was made into a rib knitting with a splicing knitting with front and back yarns. At this time, polyester yarn is added to the toe portion and the heel portion as a reinforcing yarn. The knitted socks had bamboo fibers on the inner surface, and the front side was made of yarn mainly composed of bamboo fibers, so that the touch was very good. And when this sock was worn, it had good hygroscopicity and antibacterial action, so it did not smell like the feet were damp. In addition, blood circulation improved and I felt warm. When putting on and taking off the socks, it was a good feeling without any static electricity generated while wearing.

It is a top view of one Example of the sock of this invention. It is a knitting organization chart of a flat knitting showing an embodiment of a knitting method.
