DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sock having a flat knitting structure knitted by a circular knitting machine or a double flat knitting machine, that is, a knitted sock.

[0002]

2. Description of the Related Art In order to enhance the heat retention of a knitted sock, a method of using a thick knitting yarn or a method of forming a loop pile on the sole of the foot has been adopted.

[0003]

A knitted sock using a thick knitting yarn gives a stuffy feeling, and the thicker the knitted socks, the less the flexibility and stretchability and the worse the comfort. Even if the loop pile has bulky open hair before wearing, the knitted sock on which the loop pile is formed is crushed when worn, and gives a stuffy feeling like a knitted sock using a thick knitting yarn. And the loop pile surface crushed by wearing is in the wale direction,
That is, the surface becomes a smooth surface in which the fiber fuzz is arranged in the length direction of the knitted sock, and the sole becomes slippery, giving a feeling of fatigue during walking.
Wearing thin knitted socks repeatedly gives the ankles a stuffy feel, impairs the ankle movements and gives them a feeling of fatigue and poor comfort.

[0004]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a knitted sock which does not give a feeling of stuffiness during wearing, is excellent not only in heat retention but also in flexibility and stretchability, and is comfortable to wear.

[0005]

The knitted sock according to the present invention comprises:
The sole 13 has a bag-like double knit structure of the front knitted fabric 12 and the back knitted fabric 11, and the stitches of the front knitted fabric 12 and the stitches of the back knitted fabric 11 of the sole knitted fabric are 1 per a plurality of wales. A double stitch 14 polymerized at a rate of two times is formed to join the front and back knitted fabrics 11 and 12, and the joined double stitch 14 constitutes a groove 17 continuous in the wale direction 16, At 15, three to nine bag-like cavities 19 continuous in the wale direction 16 are formed in the sole 13 between the adjacent grooves 17 between the adjacent grooves 17 and between the grooves 17. This is a first feature.

A second feature of the knitted sock according to the present invention is that, in addition to the first feature, the knitting yarn of the front knitted fabric (12) and the knitting yarn of the back knitted fabric (11) are made of a fiber material, The point is that the quality specifications of the yarn such as the twist structure (the number of twists, the presence or absence of ply twist, the number of ply single yarns, etc.) and the structure of the yarn (spun yarn or multifilament yarn) are different.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A front knitted fabric 12 and a back knitted fabric 1 shown in FIG.
The first knitting structure is a flat knitting, but these knitting structures may be rib knitting, pearl knitting, tack knitting, additional yarn knitting, or the like.
However, preferably, the groove 1 continuous in the wale direction 16 is used.
7 is formed on the surface of the back knitted fabric, that is, the inner surface of the knitted sock, and the surface of the front knitted fabric 12, that is, the outer surface of the knitted sock is made flat.
For this purpose, the knitting structure of the back knitted fabric 11 and the surface knitted fabric 12 is made flat knitting, and the knitting structure of the back knitted fabric 11 is rib knitted only in the wale constituting the groove 17.

The double stitch 14 is formed at a ratio of one wale for every 5 to 20 wales, and the groove 17 and the groove 1 constituting the double stitch 14 are formed.
It is preferable that the bag-shaped cavity 19 sandwiched between the seven is formed in the sole 13 in three to nine steps. The double stitch 14 (groove 1
When 7) is formed at a rate of 1 or more wale per 5 wales, the knitting structure of the sole 13 is not so different from a mere double flat knitting structure, and the double stitches 14 (groove 1) are formed.
When 7) is formed at a ratio of less than 1 wale for every 20 wles, the sole of the foot sole is not much different from a bag-like double flat knitting structure, and no special effect is expected.

That is, the reason why the groove 17 and the cavity 19 which are continuous in the wale direction are provided in the sole of the foot according to the present invention is that even if the sole of the sole becomes thick due to the overlap of the top knitted fabric and the back knitted fabric, the sole knitted fabric is not formed. Because the back knitted fabric is separated, the same flexibility and elasticity as when wearing thin knit socks repeatedly are secured on the sole of the foot, and the front knitted fabric and the back are repeatedly compressed when walking. The air between the knitted fabrics moves along the bag-shaped cavity 19 so as to be pushed out in the wale direction and does not give a sense of humidity, and even if a compressive stress acts along the length direction of the knitted socks during walking, the grooves 17 are not formed. Is locked by the knitting yarn 20 on the side edge of the groove 17 and the slip between the front knitted fabric 12 and the back knitted fabric 11 is suppressed, and the tiredness due to the slip is not given. The porous structure of the sole 19 is maintained, and the thermal insulation and heat insulation of the sole 13 are ensured.

In this regard, when the double stitches 14 (grooves 17) are formed at a ratio of 1 wale or more for every 5 wales, the top knitted fabric and the back knitted fabric are in close contact with each other, and each of the front knitted fabric and the back knitted fabric is allowed. Flexibility and elasticity are suppressed, and a bag-like cavity 19 that promotes the movement of air cannot be formed in the meantime, and the sole 13 has a heavy double flat knitting structure or a thick knitting yarn. It will not change much. When the double stitch 14 (groove 17) is formed at a ratio of less than 1 wale per 20 wale, the groove 1
The space between the groove 7 and the groove 17 does not rise in a ridge shape (18),
The structure of No. 9 is not maintained, and the slippage occurs between the top knitted fabric and the back knitted fabric as in the case where the sole of the sole is made into the bag-like double flat knitting structure, and the comfort is deteriorated.

For this purpose, the double stitches 14 are formed at a ratio of 1 to 5 to 20 wales, and the bag-shaped cavities 19 of 3 to 9 lines are formed in the sole 13. When the grooves 17 formed by the double stitches 14 are formed in the back knitted fabric 11 and the outer surface of the knitted sock as the front knitted fabric 12 is flattened, the grooves 17 and the grooves 17 are formed in the back knitted fabric 11 as the inner surface of the knitted socks. A plurality of ridges 18 sandwiched are formed, and the feeling of the sole 13 is good, and a comfortable knitted sock can be obtained.

If the bag-like cavity 19 is continuous in the length direction of the knitted sock, the groove 17 (double stitch 14) may be formed intermittently every few courses, and the sole 13 It does not need to be continuous in a straight line over the entire length. Such a groove 17 (double stitch 14) and a bag-like cavity 19 (ridge 1)
8) may be formed continuously also on the heel portion 21 and the toe portion 21 which are located before and after the sole portion 13.

The knitting yarn of the front knitted fabric and the knitting yarn of the back knitted fabric have the number of twists,
The presence or absence of twisting, the number of twisted single yarns and other twisted structures, fiber materials such as wool fiber, silk fiber, cotton fiber, rayon, nylon, polyester fiber, acrylic fiber, and spun yarn and multifilament yarn It is good to make it different in quality specification such as form. Preferably, for the back knitted fabric that touches the soles, fibers having excellent functionality such as fibers subjected to antibacterial treatment and deodorizing treatment and silk fibers having a function of activating the skin are used. More preferably, the back knitted fabric that touches the sole uses natural fibers having a high heat retention property such as wool fiber or silk fiber, and the surface knitted fabric that touches the floor has a physical strength such as nylon, polyester fiber, or acrylic fiber. Use excellent synthetic fibers.

[0014]

The sole 1 of the knitted sock of the present invention (claim 1).
3 is at least two sheets of the front knitted fabric 12 and the back knitted fabric 11 even when compressed during walking, unlike the case where a loop pile is formed on the sole of the foot and the knitted socks are worn repeatedly. The thickness of the knitted fabric is maintained, and a bag-like cavity 19 supported by the knitting yarn 20 on the side edge of the groove 17 is formed between the knitted fabrics. And, unlike the case of repeatedly wearing knitted socks, there is no slip between the front knitted fabric 12 and the back knitted fabric 11,
It does not give a feeling of fatigue when worn, and does not give a feeling of stuffiness because the air inside the sole inside 13 moves along the bag-like cavity 19. or,
Since the sole portion 13 is separated into the front knitted fabric 12 and the back knitted fabric 11, it does not become coarse and hard like a knitted sock using a thick knitting yarn, and is like a case where knitted socks are repeatedly worn. In addition, the movement of the ankle is not hindered, and the ankle does not feel stuffy.

According to the present invention (claim 2), the back knitted fabric that touches the sole is made of functional fibers or natural fibers such as wool fibers, silk fibers, and cotton fibers, which are rich in heat insulation and moisture absorption. Knitted socks with good durability, non-hygroscopic, non-contaminating, and highly durable synthetic fibers such as nylon and polyester fibers are used for the surface knitted fabric that touches the floor. Can be

As described above, according to the present invention, a high-quality knitting fabric which does not give a feeling of stuffiness during wearing, has good comfort, has excellent physical properties such as heat retention, flexibility, elasticity, and abrasion resistance. You can get socks.
