Furthermore, wearing this double sock has the advantage of exhibiting an immediate effect of shutting off the cold outside air and warming the entire leg as soon as it is worn.

JP 2010-138532 A

  The above-described double socks disclosed in Patent Document 1 have been invented to solve the problem that the heat retention is not sufficient because the inner pile is not knitted on the legs of the inner cylinder. Therefore, in the double socks disclosed in Patent Document 1, the inner sock body is formed by applying piles to the inner side surfaces of the toe part, the foot insertion part, and the leg insertion part via the sock knitting yarn. At the same time, the inner side surfaces of the leg insertion portion, the foot insertion portion, and the toe portion of the outer sock body are also piled and formed in the same manner as the inner side surface of the inner sock body. In this manner, the pile of the same fiber material is applied to the inner side surface of the inner sock body and the inner side surface of the outer sock body via the sock knitting yarn.

  However, Patent Document 1 describes a wool blend material for the knitting yarn for knitting the outer surface (paragraph 0041 of Patent Document 1), but the material for the knitting yarn for knitting the pile on the inner surface is a sock. Only the knitting yarn for use is described (paragraph 0031 of Patent Document 1). The thermal characteristics of the knitting yarn (fiber material) vary greatly depending on the type, and the double socks disclosed in Patent Document 1 are unlikely to achieve sufficient heat retention. That is, on the inner surface of the inner sock body and the inner surface of the outer sock body, the inner surface of the inner sock body from the skin of the human body in the double socks using the pile of the same fiber material through the sock knitting yarn The thermal conductivity from the inner side surface of the inner sock body to the inner side surface of the outer sock body becomes the same, and there is a possibility that the heat cannot be sufficiently maintained.

  The present invention has been developed in view of the above-described problems, and an object of the present invention is to provide an inner cylinder body and an outer body having substantially the same shape formed from a substantially cylindrical knitted fabric continuous at the mouth rubber portion. In a double sock in which the tubular body is folded at the mouth rubber part and the toe portions of both cylindrical bodies are sewn, by making full use of the thermal characteristics of the fiber material, providing a double sock with extremely high heat retention is there.

In order to achieve the above object, the double sock according to the present invention takes the following technical means.
That is, the double sock according to the present invention is configured so that the inner cylinder body and the outer cylinder body having substantially the same shape formed from a substantially cylindrical knitted fabric continuous at the mouth rubber portion are folded back at the mouth rubber portion. It is a double sock sewn on the toe part, and a pile is provided on a surface of the inner cylinder facing the outer cylinder, and a pile is provided on a surface of the outer cylinder facing the inner cylinder, The thermal conductivity of the fiber knitting the pile provided in the inner cylinder is lower than the thermal conductivity of the fiber knitting the pile provided in the outer cylinder.

  Preferably, the fiber knitting the pile provided in the inner cylinder is a fiber mainly composed of polypropylene, and the fiber knitting the pile provided in the outer cylinder is a fiber mainly composed of acrylic. It can be configured to be.

  According to the double sock of the present invention, the inner cylindrical body and the outer cylindrical body having substantially the same shape formed from the substantially cylindrical knitted fabric that is continuous in the mouth rubber part are folded back by the mouth rubber part, and the toes of both cylinder bodies are used. In the double socks in which the portions are sewn, it is possible to provide a double sock with extremely high heat retention by fully utilizing the thermal characteristics of the fiber material.

It is a fragmentary sectional view of the double sock of FIG. It is the elements on larger scale of the A section of FIG. FIG. 2 is a schematic cross-sectional view showing a state in which the inner tubular body is pulled out by releasing sewing at the toe portion of the double sock of FIG. 1 (ie, a knitted state).

  Hereinafter, a double sock according to an embodiment of the present invention will be described in detail with reference to the drawings. Here, there are various structures and manufacturing methods for double socks, and the present invention is not limited to a specific structure and manufacturing method. In other words, any double sock may be used as long as it has the characteristics described later (the material of the knitting yarn for knitting the pile). For example, the knitting structure of the knitted fabric constituting the double socks and the type of the knitting machine for knitting the double socks may be any type. Therefore, the schematic structure of the double socks shown below is similar to the double socks disclosed in Patent Document 1 and is merely an example.

Note that the present invention is particularly preferred as indoor socks (socks) called room socks or room shoes. Moreover, since the double socks shown below are common to the left and right, it is preferable in that the right and left are not mistakenly worn.
FIG. 1 is a schematic side view of a double sock 10 according to the present embodiment, and FIG. 2 is a perspective view showing a wearing state of the double sock 10. FIG. 3 is a partial cross-sectional view of the double sock 10, and FIG. 4 is a partially enlarged view of part A of FIG. FIG. 5 is a schematic cross-sectional view showing a state (ie, a knitted state) in which the inner tubular body 30 is pulled out after the sewing at the toe portion 12 of the double sock 10 is released. In addition, FIG.1, FIG3 and FIG.5 is the figure which assumed the state which mounted the double sock 10 or the knitted double sock 10 in the plane.

  With reference to FIG. 1 and FIG. 2, the external feature of this double sock 10 is demonstrated. As shown in FIG. 1, the double sock 10 includes an annular foot part that forms a toe part 12 to a heel part 14, a mouth rubber part 16 provided in an opening part (a mouth opening), It has the same external appearance as a normal sock, including an annular body part that constitutes the rubber part 16 to the heel part 14. For example, the body portion and the foot portion are knitted with the same knitting yarn and the same knitted fabric, the toe portion 12 and the heel portion 14 are knitted with the same knitting yarn and the same knitted fabric, and the mouth rubber portion 16 has other parts. It can be knitted with rubber knitting, etc., which is more excellent in elasticity. However, the double socks according to the present invention are not limited to such knitting yarns and knitted fabrics for reasons such as design.

Next, with reference to FIG. 3 to FIG. 5, a cross section of the double sock 10 including the features of the double sock according to the present invention will be described. As shown in FIGS. 3 and 5, the double sock 10 includes an inner cylinder 30 and an outer cylinder having substantially the same sock side surface shape integrally formed from a substantially cylindrical knitted fabric that is continuous at the mouth rubber part 16. The body 20 is folded at the rubber band 16 and the toe portions of both cylinders (the toe portion 12B (back side: Back) of the inner cylinder body 30 and the toe portion 12F (front side: Front) of the outer cylinder body 20) are sewn. Yes. In the double sock 10 according to the present embodiment, the mouth rubber portion 16 is knitted as a part of the outer cylindrical body 20, but may be knitted as a part of the inner cylindrical body 30, You may knit as a part of the cylinder 20 and the inner cylinder 30. FIG.

In the knitted state of the double sock 10 shown in FIG. 5, the inner cylindrical body 30 is inserted into the outer cylindrical body 20 in the direction of the arrow, and the toe portion 12F of the outer cylindrical body 20 and the inner cylindrical body are inserted. This double sock 10 is manufactured by sewing 30 toe portions 12B. In addition, the manufacturing method of the double socks which concerns on this invention is not limited to such a manufacturing method.
As shown in FIGS. 3 to 5, in the outer cylinder 20, the pile 24 is provided on the surface facing the inner cylinder 30, and the opposite surface of the pile 24 is the outer surface 22 of the double sock 10. Yes. The outer surface 22 touches the outside air. Further, in the inner cylinder 30, a pile 34 is provided on a surface facing the outer cylinder 20, and an opposite surface of the pile 34 is an inner surface 32 of the double sock 10. The inner surface 32 contacts the skin of the user's leg F. Since it comprised in this way, the pile 24 in the outer cylinder 20 and the pile 34 in the inner cylinder 30 have opposed. Therefore, as shown in FIG. 4, warm air can be stored in the stitches of the pile 24 itself, the stitches of the pile 34 itself, and the gap between the pile 24 and the pile 34, respectively. In the present embodiment, the pile length of the pile 24 and the pile length of the pile 34 are described differently (in order to increase the pile length of the pile 24) in order to clarify the distinction. The pile length of the double sock according to the present invention is not limited to this.

Further, the characteristics of the fibers of the knitting yarn for knitting the pile, particularly the thermal characteristics, will be described in detail below. Hereinafter, the thermal conductivity is a physical quantity obtained by dividing a heat flux density (thermal energy passing through a unit area per unit time) by a temperature gradient in heat conduction, and is the same physical quantity as the thermal conductivity.
In the double sock 10, the thermal conductivity of the fiber knitting the pile 34 provided in the inner cylinder 30 is higher than the thermal conductivity of the fiber knitting the pile 24 provided in the outer cylinder 20. Low. More specifically, the fiber knitting the pile 34 provided in the inner cylinder 30 is a fiber mainly composed of polypropylene (at least 50% by weight or more of polypropylene), and the pile 24 provided in the outer cylinder 20 is used. The fibers to be knitted are fibers mainly composed of acrylic (for example, acrylic 95% by weight, wool 5% by weight).
As described above, acrylic (thermal conductivity λ = 0.21), nylon (thermal conductivity λ = 0.24), and polyester (thermal conductivity λ = 0.15) are added to the pile 34 of the inner cylinder 30. Polypropylene (thermal conductivity λ = 0.12) having a lower thermal conductivity than a fiber having a high thermal conductivity, such as, was used.

  As a result, since the pile in the outer cylinder and the pile in the inner cylinder are opposed to each other in the double socks, the stitch of the outer cylinder pile itself, the stitch of the inner cylinder pile itself, and the pile of the outer cylinder Since warm air can be stored in the gaps between the cylinder piles, high heat retention can be achieved. Further, in addition to the heat retention by such a pile, the inner cylinder pile is knitted into a fiber material having a lower thermal conductivity (than that of the outer cylinder pile). Therefore, the heat of the user's leg F is not released to the outside air.

  A known technique may be adopted as a method for knitting the pile 24 in the outer cylinder 20 and a method for knitting the pile 34 in the inner cylinder 30. Furthermore, in the outer cylinder 20, the outer surface 22 and the pile 24 may be knitted with the same knitting yarn, or may be knitted with different knitting yarns. In the inner cylinder 30, the inner surface 32 and the pile 34 may be knitted. May be knitted with the same knitting yarn, or may be knitted with different knitting yarns. In particular, when the inner surface 32 of the inner cylinder 30 and the pile 34 that are in contact with the skin of the user's legs F are knitted with polypropylene, since the polypropylene has a low hygroscopic property, it produces an effect that it becomes warm and warm.

As described above, the double sock according to the present embodiment includes an inner cylinder body and an outer cylinder body having substantially the same shape, which are formed from a substantially cylindrical knitted fabric that is continuous at the mouth rubber part, at the mouth rubber part. In a double sock that is folded and sewn on the toe portions of both cylinders, the amount of heat released from the human body transmitted to the inner cylinder can be reduced. As a result, in addition to the heat retention by the pile of the conventional double socks (all the piles are the same knitting yarn), the heat of the user's legs F is not released to the outside air, and high heat retention can be realized.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The present invention is a double-layered structure in which an inner cylinder and an outer cylinder having substantially the same shape formed from a substantially cylindrical knitted fabric that is continuous at the mouth rubber part are folded back at the mouth rubber part and the toe parts of both cylinders are sewn. It is suitable for socks, and is particularly preferred in that the thermal properties of the fiber material can be fully utilized and the heat retention can be made extremely high.
