Abstract

PURPOSE:To improve the durability, shock resistance, and vibration absorbing quality of shoes to prevent moisture by sticking a cloth three dimensionally woven of a fiber along the inside of a shoe. CONSTITUTION:Hollow threads made of porous macromolecular membrane are used for at least a part of three dimensionally woven cloth 12, 13. A shoe insole member 15 to which the cloth 12 is adhesively bonded and a shoe instep cover member 16 to which the cloth 13 is adesively bonded are sewn to the periphery 17 of a shoe insole and opening edges of the hollow threads of the cloth members 12, 13 are located at a foot insertion opening of a shoe and the periphery 17 of the shoe insole. When the shoe touches on the ground, the hollow threads in the cloth member 12 are squeezed by the weight imposed on the foot thereby exhausting perspiration component from the opening edges of the periphery 17 of the shoe insole. Conversely, when the foot is lifted from the ground, the hollow threads in the cloth 12 which have been squeezed are restored to the former state thereby absorbing the perspiration component in the shoe efficiently through the microscopic holes of the hollow threads into the inside space. Further, portion of the outside air are taken into the hollow threads through the opening edge of the periphery 17 of the shoe insole thereby performing an easy ventilation of the whole interior of the shoe.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel ventilable shoe for preventing stuffiness.

More particularly, the present invention relates to anti-skid shoes that are generally ventilated in shoes that have an exterior made from a material that is generally not breathable.

[0003]

The most commonly used shoes in daily life are leather shoes (made of animal leather such as cowhide, sheepskin, crocodile skin or synthetic leather), which are usually worn all day long. It is often put in a state, and when the temperature is high such as summer or when it moves frequently, it causes more sweat than the body, but the foot is not an exception, so under normal conditions it becomes damp when wearing leather shoes. Even if it does not occur, in many cases, there are individual differences in the above cases, but in many cases, the inside of the shoe becomes so hot and humid that a large amount of sweat and heat generate heat. As a result, the environment in which the feet are placed becomes extremely poor, and the environment in which the pathogen that causes skin diseases such as athlete's foot, which is said to be a social disease of modern people who wear shoes, is preferred for a long time is maintained. It is not very preferable from the viewpoint of hygiene. Furthermore, the perspiration components released and released inside the shoes eventually adhere to the inner surface of the shoes,
If it is absorbed and left as it is, it has a defect that it may cause a bad odor inside the shoe.

As a method for removing the stuffiness inside the shoes and thus the bad odor, an insole containing an adsorbent such as activated carbon is inserted into the inside of the shoes to adsorb the sweating component to the adsorbent such as activated carbon to remove moisture and deodorize. It is intended to obtain an odor effect. However, such an insole is laid on the inner bottom of the shoe, and even if it can adsorb the perspiration components from the sole side of the foot, it cannot adsorb the perspiration components from the instep side.
There is a drawback that the insole must be frequently replaced so that activated carbon or the like can always sufficiently adsorb the sweating component and the component causing the bad smell released inside the shoe.

As a method for solving such a problem, pores are provided in the shoe portion corresponding to the instep of the shoe so as to allow ventilation, and the sweating component and the component causing the bad smell are directly applied to the outside of the shoe through the pores. Some of them attempt to improve the breathability by discharging, and by combining this method with the above-mentioned insole, it is possible to remove the stuffiness of the entire inside of the shoe and thus the malodor to some extent. However, although breathability can be improved, there is a limit to the provision of pores, and it is not possible to completely discharge perspiration components and components that cause foul odors directly to the outside of shoes, and in the case of rain, There is a problem that water attached to the outer surface of the shoe easily enters the inside of the shoe through the pores and gets wet.

As the leather shoes, in addition to the above-mentioned everyday shoes, there are, for example, safety work shoes or cold weather shoes (mainly boots), and such leather shoes also have the same problems as described above. is doing. Further, there are rubber shoes other than leather shoes as work shoes to be used when working in places with high humidity or high temperature, but these rubber shoes also have the problem of stuffiness more than leather shoes. Even in such a case, there is no particularly excellent solution other than the method for preventing stuffiness used in the above leather shoes, and the appearance of stuffy shoes which overcome the above problems is desired.

In addition to the above-mentioned leather shoes and rubber shoes, when a large amount of sweat is struck from the beginning such as sports shoes, threads gathered or bundled from natural or synthetic fiber materials or the like are required. By using a cloth material that has been processed and woven or knitted, shoes with excellent breathability can be obtained. In order to further improve the breathability of such shoes, a shoe having pores in the upper portion of the shoe has been put into practical use in the same manner as the above leather shoes.
However, at the same time, these cloth shoes also have hygroscopicity, and some of the perspiration components are discharged to the outside through the interstices of the woven or knitted cloth material, but inside are discharged into the fiber material and discharged outside. However, it still absorbs moisture as it is, and as with leather shoes, the problem of causing a bad odor due to the adsorbed perspiration component still remains.

Therefore, the present situation is that no shoes have been obtained which completely eliminates or prevents the stuffiness inside the shoes and the bad odor.

On the other hand, a composite material in which ordinary flat fabrics are laminated and formed into a required thickness to form a base material, and a matrix such as a resin is filled in the base material is extremely excellent in weight despite its light weight. Conventionally, it has been used as a structural material for space equipment and aircraft. However, the composite material having the above-mentioned flat woven fabric as a base material is disadvantageous in peeling force and shearing force. In order to solve these problems, a three-dimensional woven fabric in which a tissue is three-dimensionally woven has been developed. This three-dimensional fabric has a structure reminiscent of animal reticulate tissue and plant cell wall tissue as shown in FIGS. 1 and 2, and has excellent strength per weight, impact resistance, and vibration absorption performance. Since it has the advantage that it has a large cutting force, it is considered to be applied to a member that exerts a large cutting force.

Further, research and development using a hollow fiber composed of a polymer membrane having a large number of fine pores is now actively conducted in a wide field, and many products have been produced from such research and development to date. There is. For example, as a material used in the medical field, particularly as a material for artificial organs, many examples of use in dialysis machines such as heart-lung machines and artificial kidneys have been reported, and some of them have already been put into practical use. Further, many examples of using it in a filter as a material used as a filtering material for filtering impurities for purification of pure water or ultrapure water used for cleaning electronic parts such as IC are reported. Some have already been put to practical use. Further, in the use of such hollow fibers, attention is paid to the difference in the size of particles or the like between the desired substance and the impurities, and the hollow fiber is made of a porous polymer membrane having a pore size intermediate between the sizes of the desired substance and the impurities. Although a desired substance and impurities are separated and filtered using a thread, a stuffy shoe using such a hollow fiber is disclosed in JP-A-4-307297. The above invention is
A cloth material using a hollow fiber made of a porous polymer film as at least a part is attached to the inner surface of the shoe, and the end opening surface of the hollow fiber of the cloth material is inserted into the foot insertion opening of the shoe and / or the inside of the shoe. By mounting the bottom member on the periphery of the bottom member, the perspiration component in the shoe is taken in through the fine holes of the hollow fiber, and the foot insertion opening of the shoe and / or the shoe along the space path inside the hollow fiber. The hollow fibers are discharged to the outside of the shoe through the end openings of the hollow fibers arranged in the peripheral portion of the insole member. Although the sweat-preventing shoe of the above invention surely effectively removes sweating components from the inside of the shoe, it is uncomfortable to wear due to insufficient strength, shock resistance, and vibration absorption performance, so that it is difficult to wear such as when kneeling. There is still the problem that it is burdensome.

As described above, the hollow fiber made of a three-dimensional woven fabric and a polymer membrane having a large number of fine pores is not used conventionally, but a cloth material obtained by combining these is used for removing sweating components. To date, there have been no reports of shoes used as protective cloth materials in the field of use.

[0012]

SUMMARY OF THE INVENTION An object of the present invention is to provide a stuffy shoe which is excellent in strength, impact resistance and vibration absorption performance.

Another object of the present invention is to provide a stuffy shoe which is excellent in strength, shock resistance and vibration absorption performance, which can prevent stuffiness inside the shoe due to a large amount of perspiration components and can prevent a bad odor. Especially.

Still another object of the present invention is to provide shoes having excellent strength, impact resistance and vibration absorption performance, and having poor breathability by applying waterproof treatment or gloss treatment to the outer surface of the shoe, An object of the present invention is to provide a stuffy shoe which is capable of preventing stuffiness inside a shoe due to a perspiration component and preventing a bad odor even in rubber shoes having almost no air permeability.

[0015]

Means for Solving the Problems The inventors of the present invention have made extensive studies as to a shoe which is excellent in strength, impact resistance and vibration absorption, and which can prevent stuffiness inside the shoe and prevent bad odor. A cloth material formed by three-dimensionally weaving a fiber containing a hollow fiber made of a polymer membrane in at least a part thereof is used, and the end opening surface of the hollow fiber is a foot insertion opening of a shoe and / or a shoe. By attaching it to the inner surface of the shoe so that it becomes the peripheral edge of the insole member, a shoe with excellent strength, impact resistance and vibration absorption performance can be obtained. The shoe is inserted into the inner space of the hollow fiber through the hole and is inserted through the space path inside the hollow fiber, and is inserted through the foot insertion opening of the shoe and / or the end opening of the hollow fiber arranged at the peripheral edge of the shoe insole member. Ejected to the outside, especially attached to the shoe insole member In the cloth material, when the shoe is in contact with the ground during walking, the weight of the foot is added to the shoe, so that the hollow fiber in the cloth material attached to the shoe insole member is crushed and the hollow fiber is crushed. The perspiration component taken into the internal space is exhausted to the outside from the end opening at the peripheral edge of the shoe insole member. Conversely, when the foot is raised, no pressure is applied to the insole of the shoe, so that the hollow fiber in the cloth material attached to the crushed insole member returns to its original state. Therefore, at this time, the perspiration component in the shoe is efficiently taken into the internal space of the hollow fiber through the fine pores of the hollow fiber, or a part of the outside air is hollow from the end opening of the peripheral edge of the shoe insole member. Captured inside the thread.
By smoothly repeating such an exhaust operation, the sweating component can be efficiently exhausted to the outside, and it was found that the inside of the shoe can be easily ventilated, and it was found that the above object can be achieved by this, and based on this finding, the present invention Has been completed.

That is, the present invention can be achieved by a damp-preventing shoe, which is characterized in that it is constructed by attaching a cloth material in which fibers are three-dimensionally woven to the inside of the shoe.

The present invention is also a hollow fiber in which at least a part of the fiber is a polymer membrane having a large number of fine pores through which perspiration components emitted and released can pass, and the open end surface of the hollow fiber. FIG. 3 shows a sewage-preventing shoe that is mounted so as to be the foot insertion opening of the shoe and / or the peripheral portion of the shoe insole member. The present invention also provides a stuffy shoe in which the diameter of the fine holes is in the range of 0.1 μm to 2 mm. The present invention also provides that the hollow fiber has an outer diameter of 100.
The present invention shows a damp-preventing shoe having a thickness of 20 μm to 3 mm and a thickness of 20 μm to 1 mm. The present invention further shows a stuffy shoe in which the opening ratio of the fine holes of the hollow fiber is in the range of 10 to 60%. The present invention further provides that the composition ratio of the hollow fibers in the cloth material is 10 to 6

In particular, when the above-mentioned three-dimensional woven cloth material is provided on the insole of the shoe, the strength, impact resistance and vibration absorption performance should be improved, the wearing comfort should be improved, and the burden on the knees etc. should be reduced. When using a hollow fiber for at least a part of the above-mentioned cloth material, more perspiration components can be exhausted to the outside of the shoe in a short time even when viewed from the exhaust mechanism of perspiration components described in detail below. It is preferable.

That is, when the cloth material having the hollow fiber at least in part is attached to the inner surface of the shoe, the end opening of the hollow fiber is provided at the foot insertion opening of the shoe and / or the peripheral edge of the shoe insole member. It is preferably mounted so that it is positioned. With this structure, the perspiration component in the shoe is taken into the internal space of the hollow fiber through the fine pores on the surface of the hollow fiber, and the foot insertion opening of the shoe and / or the shoe along the spatial path inside the hollow fiber. The hollow fibers are discharged to the outside of the shoe through the end openings of the hollow fibers arranged in the peripheral edge of the insole member.

Particularly, in the cloth material or the like attached to the shoe insole member, when the shoe is in contact with the ground during walking, the shoe is attached to the shoe insole member to add weight to the foot. The hollow fibers in the cloth material are crushed, and the perspiration components taken into the hollow fiber internal space are exhausted to the outside from the end openings of the peripheral edge of the shoe insole member. Conversely, when the foot is raised, almost no pressure is applied to the shoe insole, so the hollow fiber in the cloth material attached to the crushed shoe insole member is
In order to return to the original state, at this time, the perspiration component in the shoe is efficiently taken into the inner space of the hollow fiber through the fine holes of the hollow fiber, or a part of the outside air is added to the edge of the peripheral edge of the shoe insole member. It is taken into the inside of the hollow fiber through the opening. By smoothly repeating such an exhaust operation, the perspiration component can be efficiently exhausted to the outside, so that the entire inside of the shoe can be easily ventilated.

The cloth material thus obtained is preliminarily processed according to the shape and size of the inner surface suitable for the shoe body. When hollow fibers are used for at least a part of the cloth material, the foot insertion opening and / Or there is a shoe insole attached to the peripheral edge of the shoe so that the end opening of the hollow fiber is located. In addition to this, it is applied only to the insole of the shoe, It is applied only to the cloth material for the insole of the shoe, which is installed so that the end opening of the hollow fiber is positioned in the section, and is applied only to the upper part of the shoe, and it is hollow at the foot insertion opening of the shoe and the peripheral portion of the insole member.

[Table 1]

Example 9 One pair of the shoe for preventing stuffiness of one leg for the right foot of Example 1 and one shoe for the left leg of Comparative Example 1 were used as one pair, and this was used for 6 months and every 8 hours every other day. After using it in everyday life, when I smelled the smell of the shoes, the anti-steam shoes had a lower offensive odor than the non-steamed shoes, and the odorous components did not easily adhere even after continuous use. It was confirmed.

Further, no apparent change was observed in the cloth material for the insole portion and the cloth material for the instep in the shoe for preventing stuffiness of Example 1.

Further, as a result of cutting out a part of the inner surface of the shoe and observing bacteria causing skin diseases with a microscope, the shoes for preventing stuffiness are much more liable to have bacteria than the shoes which are not stuffy. It was also confirmed that the number in the unit area was small.

Industrial Applicability The present invention provides a stuffy shoe which is constructed by attaching a cloth material, in which fibers are three-dimensionally woven, to the inside of the shoe. By using a three-dimensionally woven cloth material, it is possible to obtain a shoe having excellent strength, impact resistance, and vibration absorption performance, as compared with conventional shoes.

By using hollow fibers in at least a part of the three-dimensionally woven cloth material, it is possible to prevent stuffiness inside the shoe due to a large amount of perspiration components and prevent bad odor.

Furthermore, the outer surface of the shoe is subjected to a waterproof treatment or a gloss treatment to prevent the stuffiness of the inside of the shoe due to the perspiration component, even in the case of a shoe having poor breathability, or even a rubber shoe having almost no breathability. It can prevent foul odors and eventually prevent skin diseases.
