In addition, since the sock and the rubber layer are integrated, comfort is good and durability is high.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-drying sock having excellent moisture retention, good comfort, and high durability.

[0002]

2. Description of the Related Art In low seasons such as winter, skin becomes excessively dry and keratinized. The keratinization of the skin impedes the smooth replenishment of water and causes the degree of roughness to progress more. For the face and fingers, it can be groomed frequently by applying creams.However, in the case of the soles of the feet such as heels and toes, it is not well-groomed and excessively rough skin due to keratinization. Often become. In particular, in the case of an elderly person, the skin becomes rough due to the keratinization of the soles of the feet, and cracks and the like may occur, leading to pain.

[0003] In order to prevent the occurrence of such symptoms, a method of wearing thick socks is conceivable, but it cannot be said to be a preferable method in that the feet become stuffy or large footwear is required. . In order to prevent partial drying of the heels of the feet, socks have been proposed that are partially non-breathable to increase the moisture retention. For example, Japanese Unexamined Patent Publication No. 4-289202 proposes a sock in which a non-breathable sheet made of a polyvinyl chloride film is sewn so as to surround a heel portion. Socks have been proposed in which a soft vinyl chloride resin paste is applied to the heel portion of the socks and solidified to form a moisturizing portion.

However, the invention described in Japanese Patent Application Laid-Open No. 4-289202 cannot be said to have good comfort due to a sense of incongruity in a sewn portion when worn, and also has insufficient durability in practical use. . In addition, 3-997
The invention described in the specification of JP-A-07-2007 is not sufficient in terms of comfort due to poor elasticity of polyvinyl chloride.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an anti-drying sock in which the desired portion of the sock is made non-breathable to enhance the moisture retention of the foot and to provide satisfactory comfort and durability. I do.

[0006]

According to the present invention, there is provided a sock for drying, characterized in that the sock has a rubber layer on at least a part or all of a portion of the sock where the sole contacts the sole. . The present invention also provides, as Claim 2, the drying prevention sock according to Claim 1, wherein the rubber layer is formed on a portion including the heel or toe of the sock. According to a third aspect of the present invention, there is provided the anti-drying sock according to the first or second aspect, wherein the rubber layer is formed by immersing the sock in rubber latex, followed by drying and solidifying. In addition, the present invention provides, as claim 4, the anti-drying sock according to claims 1, 2 or 3, wherein the rubber layer is formed on the outer surface of the sock.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The anti-drying sock of the present invention has a rubber layer on at least a part or all of a portion of the sock where the sole contacts. Therefore, the rubber layer can be formed on a desired portion other than the portion where the sole of the sock contacts, for example, the entire finger of the sock, the portion where the instep or ankle contacts, and the like. In addition, this rubber layer may be formed on either the inner surface or the outer surface of the sock, and may be formed on the same portion on both side surfaces or on different portions.

[0008] The anti-drying sock of the present invention has a rubber layer on one or both of the toe and the heel where the sole of the sock contacts, in order to protect the heel and the toe, which are particularly keratinized. Is preferred. Further, the rubber layer is preferably formed on the outer surface of the sock in order to eliminate a feeling of discomfort when worn and enhance comfort.

Next, an example of the method for producing the anti-drying sock of the present invention will be described with reference to the drawings. However, the method of producing the anti-drying sock of the present invention is not limited to the following method. FIG. 1 to FIG. 3 are conceptual diagrams for each step for explaining the method for producing a sock for preventing drying according to the present invention.

First, in a first step, as shown in FIG. 1, a sock 1 is mounted on a metal last 2 made of aluminum or the like. The sock 1 does not require any special material, shape, size, knitting method, and the like, and a commercially available product can be used as it is.

Next, in a second step, as shown in FIG. 2, a portion of the sock 1 where a rubber layer is to be formed is immersed in a latex liquid 3 for a required time and then pulled up. By this immersion treatment, the portion of the sock 1 where the rubber layer is to be formed is impregnated with the latex liquid 3.

The rubber latex liquid 3 used in this step may be a natural rubber latex or a synthetic rubber latex. The rubber latex liquid 3 can contain various additives such as a vulcanizing agent, a vulcanization accelerator, a filler, a reinforcing agent, a plasticizer, a softening agent, and an antioxidant, which are compounded in general rubber products. . The rubber latex liquid 3 may be mixed with a coloring agent such as a pigment so that the rubber layer has the same color as that of the sock or a different color to impart fashionability.

The solid content concentration, viscosity, etc. of the rubber latex in the rubber latex liquid 3 can be appropriately set in relation to the immersion time (the amount of the rubber latex liquid 3 impregnated).
For example, if the viscosity is increased by pre-vulcanizing the rubber latex liquid 3 to improve the adhesion, the immersion time can be reduced.

Next, in a third step, the latex liquid 3 impregnated in the sock 1 is dried and solidified. The drying and solidification in this case varies depending on the type of the latex liquid, the amount of impregnation, and the like. When a natural rubber latex liquid is used, the drying and solidification is carried out at about 80 to 110 ° C. for about 15 to 60 minutes.

By the processing of the first to third steps,
As shown in FIG. 3, it is possible to obtain a drying prevention sock in which the rubber layer 4 is formed on the heel portion and the rubber layer 5 is formed on the toe portion. The thickness of the rubber layers 4 and 5 is not particularly limited as long as the portion is kept air-permeable and does not give an uncomfortable feeling when worn. Usually, a thickness of about 1 mm or less is sufficient. is there.

EXAMPLES The present invention will be described in more detail with reference to the following Examples, but it should not be construed that the invention is limited thereto.

Example 1 Drying prevention socks having rubber layers on the heel and toe portions were manufactured by the method shown in FIGS. As the socks, a pantyhose made of a nylon-polyurethane blend was used. As the rubber latex liquid, a natural rubber latex liquid (solid concentration: 45% by weight, viscosity: 10 cP) containing a required amount of a vulcanizing agent and a vulcanization accelerator was used. The immersion time was about 0.5 minutes or less for both the heel and the toe. Drying and solidification was performed at about 90 ° C. for about 15 minutes.

When the sock for drying prevention obtained in this manner was pulled several times with both hands, the sock body and the rubber layer were integrated. It could be stretched in the same way. Also,
In the same manner, it was held with both hands and repeatedly violently expanded and contracted several hundred times or more in total. However, since the sock main body and the rubber layer were integrated, no slip, peeling, cracking, etc. occurred in the rubber layer.

The drying prevention socks were applied to 14 men and 1 woman
Six people, a total of 30 people, were asked to wear a panel of 60 years or older for 2 weeks, and 27 people gave the evaluation that they were comfortable, and all of them got the evaluation that they had moisture retention.

[0020]

According to the dry socks of the present invention, the effect of the rubber layer enhances the moisturizing effect of the feet, so that the feet can be protected from excessive drying and keratinization can be prevented.
In addition, the anti-drying socks of the present invention have good comfort and high durability.
