Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to seamless stockings. More particularly, the present invention relates to seamless stockings that are useful for preventing deterioration of hallux valgus, which has been particularly noticeable in recent years as an obstacle that occurs in a foot due to long-term wearing of shoes and causes various pains to a user. The term "seamless stockings" used herein refers to pantyhose, short stockings, long stockings, seamless tights, and the like that are mainly knitted by a circular knit sock knitting machine using polyamide synthetic fiber yarns.

[0002]

2. Description of the Related Art Hallux valgus is a progressive deformity disease in which the toe of the foot bends toward the fifth toe, thereby causing pain from the sole to the medial part of the toe joint. As shown in FIG. 1, the lateral metatarsal ligament 9 is loosened by wearing for a long time, and as a result, the inside of the head of the first metatarsal bone 7 opens toward the toe 2 and the toe 2 bends toward the fifth toe 6. It is a disease. Hallux valgus is a disease that has spread for 200 years in Europe and the United States.
It has increased rapidly, especially among women, over the years.

[0003] In order to prevent the occurrence of hallux valgus, the most preferable measure is to wear shoes of an appropriate shape.
In order to prevent the deterioration of the hallux valgus, which has occurred once, it is said that the lateral metatarsal ligament is fixed by various supporters so as not to be loosened. Based on this idea, as shown in FIG. 2, an annular zone 12 having a high tensile resistance is applied to the foot portion 11 so as to cover a portion corresponding to the lateral metatarsal ligament (9 in FIG. 1) of the wearer's foot. Pantyhose 1
No. 0 is commercially available, and this pantyhose is said to be effective in preventing hallux valgus deterioration.

[0004]

Although this known pantyhose has an excellent function against hallux valgus, it is difficult to wear the pantyhose when wearing the pantyhose because the zone with strong tensile resistance is provided in the foot portion in an annular shape. Has aesthetic problems. In other words, the zone with high tensile resistance must be a zone with a large amount of yarn per unit area in some form,
As a result, other areas must be darkened. In addition, in this pantyhose, since a zone having a high tensile resistance is provided in an annular shape, when viewed from above in a worn state, a dark zone can be clearly seen in a band shape above the foot portion. Hallux valgus itself is not a shameful disease, but many women do not like the state of being known and talked about. Therefore, except when wearing boots or other shoes where the foot part is completely hidden, when wearing pumps etc., make sure that even if it is functionally desired, others will not notice as much as possible and do not want to be known The female psychology of hope seems to be quite strong.

An object of the present invention is to provide a seamless stocking which has the same appearance as that of a conventionally known seamless stocking when worn and which is useful for preventing deterioration of hallux valgus in accordance with the above-mentioned female psychology. .

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to provide a zone of a sole of a seamless stocking with a zone having a higher tensile resistance than the other portion, and the width of the zone in the course direction is viewed from above when worn. This is sometimes achieved by seamless stockings, characterized in that they are defined within a range hidden by the user's feet. The configuration of the seamless stocking of the present invention is not limited to the pantyhose exemplified in the prior art, but can be applied to all seamless stockings knitted by circular knit sock knitting machines including long stockings. The zone with a high tensile resistance is preferably provided in a part of the sole so as to cover the lateral metatarsal ligament of the wearer, and by providing the zone with a high tensile resistance in this way, the lateral metatarsal ligament is not loosened. Can work. Further, in the seamless stocking of the present invention, the zone having a high tensile resistance is hidden by the wearer's foot when worn, so that the beauty of the wearer's foot is not spoiled.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a zone provided on a part of a sole of a seamless stocking having a higher tensile resistance than another part has a higher tensile resistance in a width direction of the sole, that is, a course direction of a knitted fabric. Is preferred. The zone having a high tensile resistance can be formed by changing the knit fabric structure of the seamless stocking, or knitting this zone with a yarn having a high elastic recovery force. As a special method, a zone having a high tensile resistance may be formed by suppressing the elasticity of the knitted fabric at that portion by staking the knitted fabric on the seamless stocking using another yarn.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing an example of the seamless stocking of the present invention. FIG. 3 is a side view showing an example of the seamless stocking of the present invention when worn. In a portion corresponding to the lateral metatarsal ligament of the foot when the sole 15 which is the sole portion of the foot portion 14 of the seamless stocking 13 shown in FIG. 3 is worn, a zone 17 having a higher tensile resistance than other portions of the seamless stocking 13 is provided. Are located. FIG. 4 is an arrow A in the side view of FIG.
It is the top view of the sole 15 seen from the direction. As is apparent from FIG. 4, since the zone 17 having a high tensile resistance is disposed in the portion of the sole 15 shown in FIG. 4, the direction of the arrow B in FIG. 3 (the direction from the back side of the paper surface in FIG. 4). With foot part 15
By being hidden by the feet when watching, the beauty of the wearer's feet is not impaired.

The size of the zone 17 having a strong tensile resistance is as follows.
The size can be arbitrarily selected as long as it is within a range hidden by the wearer's foot when worn. In an example in which the cylinder shown in FIG. 4 is knitted by a circular knit sock knitting machine having 400 knitting needles, the distance l ₁ from the boundary line of the toe portion 16 of the sole 15 to the zone 17 may be 65 to 70 courses.
Incidentally distance l ₂ from the boundary line to the edge of the toe portion 16 in this case is 80 to 85 courses. As shown in FIG. 6, a preferred width W (course direction) of the zone 17 is W.
Is 100, and the number of courses having a width C in the length direction (wale direction) is 360. Since the zone 17 is a zone having a high tensile resistance as described above, the zone 1
7 is hard to stretch. The following is an example of this as a stretch dimension indicating the ease of elongation of the knitted fabric. That is, the stretch dimension when pulled in parallel to the course direction at the position indicated by S _{1 to} S ₁ ′ in FIG. It is. On the other hand, the stretch size at the position indicated by S _{2 to} S ₂ ′ including the zone 17 having a high tensile resistance is 20 cm, and is hardly stretched much more than the position of S _{1 to} S ₁ ′. It turns out that it is what tightens. The stretch size at the position indicated by S _{3 to} S ₃ ′ is 22 cm, and the sole 15 and the toe 1
The stretch size at the position indicated by S _{4 to} S ₄ ′, which is the boundary line of No. 6, is 25 cm. In this case, the stretch dimension in the course direction of only the zone 17 is 12 cm for a knitted fabric having a wale number of 100. In this case, for reference, the stretch dimension in the wale direction in this case was 16 cm for a knitted fabric having 360 courses.

FIG. 5 is a drawing similar to FIG. 4 showing a variation of the seamless stocking of the present invention. As is clear when FIG. 5 is compared with FIG. 4, in the seamless stocking 15a shown in FIG. 5, the toe portion 16 'is larger than the toe portion 16 of the seamless stocking 15 shown in FIG. It is organized so that there is room. As described above, the toe portion 16 ′ is provided so that the toe has a margin.
Knitting is preferable because it helps to prevent deterioration of hallux valgus.

Next, an example of a knitting structure used for knitting a zone having a high tensile resistance in the seamless stocking of the present invention will be described below with reference to FIGS. As described above, various methods can be employed for forming a zone having a high tensile resistance. However, as shown in FIG. 7, the structure of the knitted fabric is the same as that of the conventional seamless stocking,
It is preferable to knit using a yarn having a strong elastic recovery force in a specific course, or to adopt a float structure in a specific course as shown in FIG. The knitting structure of the knitted fabric 18 shown in FIG. 7 is a sheet-knit structure, which is a knitting structure usually used for knitting of seamless stockings, and the entire knitted fabric is usually knitted with the same polyamide fiber multifilament. A textured yarn is usually used as the polyamide fiber multifilament, but an unprocessed yarn may be used. In order to knit the zone 17 having a high tensile resistance, courses indicated by 2F and 4F use the same textured or unprocessed yarn of polyamide fiber multifilament as the yarn knitting the other part of the seamless stocking. , 3F, spandex yarn or covering yarn (shown by thick yarn in the figure)
Is used. The covering yarn referred to here is a single covering yarn in which a spandex yarn is used as a core yarn and a synthetic long fiber yarn is wound around the core yarn in a certain direction as a sheath yarn, or a synthetic long fiber texture is further formed on the single covering yarn. A double covering in which the yarn is wound in the opposite direction.
As shown in FIG. 7, since the spandex yarn having a high elastic recovery force or its covering yarn is arranged at a constant ratio in the course direction, the tensile resistance of the zone 17 can be increased.

The knitting structure of the knitted fabric 19 shown in FIG. 8 is a 1: 3 float structure which is a typical float structure. 2F, 4
The yarns of the course indicated by F are knitted in the same knitting structure as the other parts of the seamless stockings, and the yarns of the courses indicated by 1F and 3F (shown by thick yarns in the figure) are knitted in a 1: 3 float structure. In the float structure, since there is a yarn portion which goes straight in the course direction indicated by 20 in FIG. 8, in a knitted fabric of this structure, it is difficult to elongate against tension in the course direction, that is, the tensile resistance becomes strong. In the knitted fabric shown in FIG. 8, it is preferable to use a spandex yarn or a covering yarn for the yarns of the courses indicated by 1F and 3F. This is preferable because the tensile resistance in the zone 17 can be further increased by the synergistic effect of the enhancement of the tensile resistance by the knitting structure and the enhancement of the tensile resistance by giving the yarn itself an elastic recovery force.

Hereinafter, the present invention will be described in more detail with reference to Examples. Example 1 A polyamide long fiber textured yarn 15d / 5f is supplied to a circular knit sock knitting machine having 400 needles to knit a seamless stocking illustrated in FIG. In order to make 17 a zone with a high tensile resistance, a double covering yarn was used in the course of 1F and 3F in the sheeting structure shown in FIG. As the double covering yarn, a spandex 15d is used as a core yarn, and a polyamide long fiber (original yarn) 12d / 7f is wound around the core yarn (the number of windings is 1).
860 turns / cm), and a polyamide long fiber (raw yarn) 12d / 7f wound thereon in the reverse direction. The width W (FIG. 6) in the course direction of the zone 17 having a high tensile resistance is 1
The width C in the 00-wale and wale directions (FIG. 6) was 360 courses, and the length of l ₁ shown in FIG. 4 was 65 courses. The stretch dimensions of each part are shown below. _{S 1 ~S 1 '27cm S 2} ~S 2' 20cm S 3 ~S 3 '22cm S 4 ~S 4' 25cm Note length of l ₂ shown in FIG. 4 was 80 courses.

Plural pieces of the obtained seamless stockings of Example 1 were lent to 10 women suffering from hallux valgus, and a wearing test was conducted for 10 weeks (50 days) under the condition of daily washing, but daily wearing. The shoes worn cannot be specified because there are individual differences, but rather, those worn by the wearer that they feel tight are used. After the wearing test, ten wearers were interviewed, and a feeling of comparison with conventional seamless stockings was obtained. Wearing feeling Wearing feeling is better than conventional products 6 No difference from conventional products 4 Impact on hallux valgus Does not seem to be deteriorating 5 People is slightly deteriorating like conventional products 5

Example 2 A seamless stocking was knitted under the same conditions as in Example 1. However, FIG. 8 shows a zone having a high tensile resistance:
A double-floating yarn knitted in a 3-float structure and similar to that in Example 1 was used for the courses of 1F and 3F. In addition, the shape of the toe portion is set to have a margin with respect to the toe of the foot as shown at 16a in FIG. Zone 17a with strong tensile resistance
The width W in the course direction is 100 wales, the width C in the wale direction is 360 courses, and the length l ₁ shown in FIG.
0 courses. The stretch dimensions of each part are shown below. _{S 1 ~S 1 '27cm S 2} ~S 2' 18cm S 3 ~S 3 '20cm S 4 ~S 4' 26cm Note length of l ₂ shown in FIG. 4 was 100 courses.

A wearing test was performed on the obtained seamless stocking of Example 2 in the same manner as in Example 1, and a feeling of comparison with the conventional seamless stocking was obtained. Feeling of wearing Good feeling of wearing compared to conventional products 8 No difference from conventional products 2 Effects on hallux valgus Does not seem to have deteriorated 6 Somewhat worse like conventional products 4

[0017]

The seamless stocking of the present invention is provided with a zone having a higher tensile resistance in one part of the sole than in the other part. Helps prevent hallux valgus deterioration during use. Since the zone having a high tensile resistance is provided in a part of the sole, it is not noticed by others when worn, and there is no difference in appearance from conventional seamless stockings.
