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.

にもなる等の欠点を有していた。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.

に取り替えなければならない等の欠点がある。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.

等の問題がある。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.

した蒸れ防止靴の出現が望まれている。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.

ている。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.

用などが考えられている。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.

かってしまうという問題点が残っている。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.

を完成させるに至った。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.

Instead of using the cloth material for the insole of the shoe and the cloth material for the upper part of the shoe so that the end openings of the hollow fiber come to the peripheral portion of the shoe part and the shoe insole member, the shoe is applied to the entire inner surface of the shoe main body. Example 5 except that a bag-shaped cloth material in which the insole of the shoe and the upper part of the shoe are integrally formed by attaching the hollow fiber so that the end opening of the hollow fiber is located only in the foot insertion opening of Example 5
A shoe for preventing stuffiness was produced in the same manner as in. Subsequently, Example 1
An evaluation test was performed on the anti-steam shoes obtained by the same operation as above. As a result, with regard to impact resistance, 10 people answered that they did not feel pain in their knees and that they walked easily, while the rest of them answered that they felt some pain in their knees and did not feel particularly easy to walk. The results are shown in Table 1 for the dampness of the shoes and the absorbability of vibration.
