(Third embodiment of the present invention)
The stocking which concerns on the 3rd Embodiment of this invention is demonstrated based on FIG.5 and FIG.6. FIG. 5 is a pile knitted fabric pattern diagram on the back side of the knitted fabric on the instep side of the stocking according to the present embodiment, and FIG. 6 is a cross-sectional view taken along line BB in the stocking described in FIG.

  In each of the drawings, the stocking according to the present embodiment is knitted with a pile knitted fabric in the middle foot point portion 4, the interphalangeal joint portion 5 and the heel portion 6 similarly to the stocking according to the first embodiment. In addition to this knitting configuration, on the back side of the foot side portion, the corresponding portion of the shin side midfoot point 31 and the heel side midfoot point 32 has a larger dynamic friction coefficient than the outer surface and a compressive strain up to the maximum pressure, A special knitted fabric with a compression characteristic that satisfies at least one of compression energy up to the maximum pressure and compression recovery performance is knitted by circular knitting, and each pile knitted knitted fabric is backed by a foot during a walking operation of the wearer The knitted fabric is knitted with a striped knitted fabric in a direction crossing the path Q of the center of gravity movement.

  As described above, the striped knitted fabric in the pile knitted fabric of the middle foot point portion 4 and the heel portion 6 is configured to intersect the route Q of the center of gravity movement of the sole, so that it follows the route Q during walking. The stress generated sequentially is alleviated, and the uneven portion formed of the striped knitted fabric of the pile knitted fabric is reliably transmitted to the sole of the wearer, thereby enabling stable walking.

  In each of the above-described embodiments, the pile knitted fabric has a dynamic friction coefficient larger than that of the fabric and a compression characteristic satisfying at least one of compression strain up to the maximum pressure, compression energy up to the maximum pressure, and compression recovery. However, it is possible to knit large or any one of compression strain up to the maximum pressure, compression energy up to the maximum pressure, and compression recovery. In addition, the stress relaxation characteristics can be greatly knitted.

For the stockings used in Example 1, the toes were knitted in a pile knitting manner, and three types of prototypes 1, 2, and 3 were produced.
1. Knitted double nylon covered yarn and nylon knitted fabric 3: 1 pile knitting (hard pile PH)
2. Nylon double covered yarn and nylon knitted fabric Knitted into a 3: 1 pile knitting pattern for every course (every other layer of hard pile Ph)
3. All wooly nylon thread knitting knitting 3: 1 pile knitting (soft pile Ps)
A normal type stocking was used as a control for comparison.

  The experimental items are the friction coefficient between the human skin (upper arm inner side) and the stockings, the friction coefficient between the stockings and the shoe material (cowhide), the compression characteristics and stress relaxation characteristics of the stockings, and the pressure applied to the toes during walking. It is a subjective evaluation. For subjective evaluation, four sensitivity values, (a) standing comfort, (b) walking comfort, (c) soft feeling during walking, and (d) compressive feeling during walking, are compared with a paired comparison method (Ura (Variant method). That is, different types of stockings were worn on the left and right, and one of the other stockings was compared with the other, and a five-step evaluation was performed. Each subject evaluated in 12 combinations.

In Example 1, the static friction coefficient and the dynamic friction coefficient between skin and stockings, stockings and shoe material (cowhide) were measured.
From this measurement result, under any pressure, the soft type Ps is the most slippery between the skin and stockings (pile knitted surface: back side), and the stockings (front surface) and the shoe material are slippery. Since it occurs between the stockings, it was considered that shoe rubs are unlikely to occur.

ソフトタイプＰｓの圧縮ひずみ量（ε）は強圧下でノーマルタイプの約９倍であり柔らかく、圧縮エネルギー（ＷＣ）は、強圧下でノーマルタイプの約２倍であり柔らかく、且つ最大圧までの応力緩和特性が大きいことがわかった。

The compressive strain (ε) of the soft type Ps is about 9 times that of the normal type under high pressure and soft, and the compression energy (WC) is about twice that of the normal type under high pressure and soft, and the stress up to the maximum pressure. It was found that the relaxation characteristics are large.

また、圧縮回復性はハードタイプＰＨで高かったが、ソフトタイプＰｓでもノーマルタイプより若干回復性がよいことがわかった。次に、６ｋＰａからの圧縮ひずみ、最大圧までの圧縮エネルギー、圧縮回復性のうちの少なくとも一を満足する圧縮特性の結果から、ＰｓおよびＰｈはノーマルタイプＮに比べて粘弾性成分が大きく、緩衝効果が認められた。

Moreover, although the compression recovery property was high with the hard type PH, it was found that the soft type Ps has a slightly better recovery property than the normal type. Next, from the result of the compression characteristics satisfying at least one of the compression strain from 6 kPa, the compression energy up to the maximum pressure, and the compression recoverability, Ps and Ph have larger viscoelastic components than the normal type N, and the buffer The effect was recognized.

また、歩行時の足の第一指（親指）と第五指（小指）部分で接触圧を測定した。その結果、ソフトタイプＰｓで平均接触圧が低くなることがわかった。

In addition, contact pressure was measured at the first finger (thumb) and fifth finger (little finger) part of the foot during walking. As a result, it was found that the average contact pressure was lowered with the soft type Ps.

In the subjective evaluation, “standing comfort” and “walking comfort” were higher in all prototypes than in the normal type. “Softness during walking” was the highest evaluation of the soft type Ps. The hard type of PH and Ph had a large “feeling of pressure”, but the soft type was evaluated as not feeling pressure as much as N (difference analysis result, difference between samples p <0.01).
