Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shoe insole which uses tourmaline and can thereby keep a foot healthy. 2. Description of the Related Art Tourmaline, which is also called tourmaline, has characteristics such that electrodes are formed at both ends of its crystal to generate negative ions, emit far-infrared rays, and have a surface active effect. . The properties of these tourmalines have a positive effect on the human body, but among them, the action of minus-on on the human body has been attracting much attention, for example, a beauty promoting action, an analgesic action, a stress relieving action, It is known to have various effects such as a blood circulation promoting action. In recent years, by utilizing the characteristics of tourmaline to generate negative ions, it is often used as a decorative product as it is, and also used in cosmetics or miscellaneous goods. In particular, the development of shoe insoles using tourmaline for the purpose of promoting foot health has been studied, and various types have been proposed. For example, Japanese Utility Model Registration No. 3068927 discloses a shoe insole provided with three layers of an upper layer, a middle layer, and a bottom layer, wherein the upper layer is a nonwoven fabric of synthetic polymer fibers in which fine particles of tourmaline ore are sealed. Shoes, wherein the middle layer is formed of a nonwoven fabric of a natural polymer fiber in which fine particles of tourmaline ore, fine particles of activated carbon, and an electrically conductive material are enclosed, and the bottom layer is formed of a cushion material. The insole is disclosed. JP-A-2002-051805 has a two-layer structure in which a core layer and a surface layer are integrally bonded. The core layer is made by uniformly mixing tourmaline powder into a polypropylene resin foam. Discloses a tourmaline-containing insole, which is a mesh made of synthetic resin fiber. [0003] However, the shoe insole disclosed in Japanese Utility Model Registration No. 3068927 has a structure in which fine powder of tourmaline is enclosed in a synthetic polymer fiber tissue. However, it is hard to say that the negative ions are effectively emitted outside. Also, in the shoe insole disclosed in Japanese Patent Application Laid-Open No. 2002-051805, since tourmaline is dispersed in the foam, the emission of negative ions is suppressed by the foam, and there is a problem in the emission effect. Remains. Means for Solving the Problems The present invention has been made in view of the above-mentioned circumstances, and its specific structure is a surface fabric made of a polyester woven fabric, a vinylidene chloride resin monofilament. A first intermediate material consisting of a woven fabric, a second intermediate material having a mixture of tourmaline powder and a binder adhered to the surface of a polyester nonwoven fabric, a third intermediate material consisting of a woven fabric of vinylidene chloride resin monofilament, and a vinylidene chloride resin The present invention relates to a shoe insole formed by laminating a backing fabric made of a monofilament woven fabric in this order, fusing the laminate into a shoe insole shape, and adhesively integrating an outer peripheral edge thereof. In a preferred embodiment thereof, the second intermediate material relates to the above-mentioned shoe insole, wherein the mixture is applied to a surface of a polyester nonwoven fabric in a striped pattern, preferably such that the strips are applied at a constant interval. . DESCRIPTION OF THE PREFERRED EMBODIMENTS The shoe insole according to the present invention basically has a five-layer structure in which a top material, a first to third intermediate material and a back material are laminated in this order, Between the three intermediate materials, there is a second intermediate material made of a polyester nonwoven fabric to which tourmaline is attached by a binder. It is necessary that the outer fabric is formed of a woven fabric so as to prevent passage of negative ions and the like generated from the tourmaline component of the second intermediate material as much as possible. As described above, the possibility that the negative ions are hindered is very low due to the fact that the fabric is made of a highly air-permeable fabric. In addition, since the outer fabric is also in direct contact with the sole of the foot, it is preferable that the fabric be made of a comfortable material. On the other hand, the material of the backing cloth may be unified to the same material as the front cloth, but since it is a part that does not relatively require comfort and aesthetics, for example, even if breathability is selected as the highest priority, I do not care. As the material of the first and third intermediate materials, those having good air permeability are preferable. In particular, it is necessary that the first intermediate material is formed of a woven fabric like the outer fabric. In the present invention, the second intermediate material is prepared by mixing tourmaline, which has been finely pulverized in powder form in advance, with a binder and a solvent, and then applying an appropriate amount of the mixture to a surface of a polyester non-woven fabric which faces upward when worn. , The surface) and cured. The tourmaline used is preferably in the form of a powder, but may be in the form of granules if the wearing comfort is not deteriorated. These powdery or granular tourmalines can be easily attached to the polyester nonwoven fabric using a binder such as an adhesive or a binder. Needless to say, additives such as a solvent and a volatile agent may be appropriately mixed as needed. The mixture is applied to the surface of the polyester non-woven fabric, for example, in the form of stripes, preferably at regular intervals. In this case, the stripes coated with tourmaline are not limited to linear stripes, but may be wavy stripes or zigzag stripes. The mixture of tourmaline and the binder may, of course, be applied over the entire front and back of the polyester nonwoven fabric, but it is convenient to apply the mixture to the surface of the nonwoven fabric from the viewpoint that the generated negative ions sufficiently act on the soles. And preferred. An embodiment in which a deodorant and a bactericide are added to the mixture, if desired, is also preferable in view of the effect of preventing odor of the soles. Also, the shoe insole of the present invention does not need to be specified as a five-layer structure, for example, a three-layer structure consisting of a surface cloth, a single intermediate material made of a polyester nonwoven fabric to which a mixture of tourmaline powder and a binder is adhered, and a back cloth. It may be a structure. [0007] Examples of the material constituting the front fabric, the first to third intermediate materials, and the back fabric include polyester, polypropylene, polyamide (nylon), polyvinyl chloride, and polyvinylidene chloride. As the material of the surface material, a woven fabric mainly composed of polyester or polypropylene is preferable. As the material of the first and third intermediate materials and the material of the back material, monofilaments of polyvinylidene chloride are preferable. Is preferably a polyester nonwoven fabric. Other fabrics for the front and back fabrics include, for example, wool, cotton, hemp, rayon, and woven or knitted fabrics made of a blend of the above polyester, polyamide and these fibers. In addition, the weaving method of the woven fabric and the knitting method of the knitted fabric used for these fabrics are not particularly limited. Can be used. The double raschel woven fabric is made of, for example, polyester fiber, and the honeycomb woven fabric is made of, for example, polypropylene monofilament. In addition, by performing so-called melamine processing on the material of the shoe insole, coloring and yellowing of the material can be suppressed. The melamine processing is performed by dipping polyester fiber cloth into a melamine resin solution (so-called dobuke) using, for example, a rebound-hardened finishing material (main component: self-crosslinkable acrylic vinyl acetate copolymer resin). By drying at about 160 ° C. Further, in the case of the surface cloth, the fiber used as a material may be a specially processed fiber such as an antibacterial treatment or a bacteriostatic treatment which suppresses the growth of bacteria and enhances the deodorization. Antibacterial and bacteriostatically processed polyester fiber is a fiber with high antibacterial properties imparted by deeply fixing a highly safe antibacterial agent and bacteriostatic agent from the polyester fiber surface to the inside of the fiber like a dye. . The production of the shoe insole is easily carried out by a conventional method. For example, as shown in JP-B-39-6288, a shoe insole provided with equipment capable of high-frequency heating is provided. Using a manufacturing apparatus, first, a laminated body in which the front fabric, the first to third intermediate materials, and the back fabric are superimposed is placed on the flat-plate-shaped lower electrode, and then the shoe insole is placed thereon. A high-frequency current is applied between the upper and lower electrodes while pressing and pressing the upper electrode having a sharpened outer periphery in a shape mold, thereby heating the laminate between the electrodes, The laminate is blown into a shoe insole shape, and at the same time, the outer peripheral edge thereof is bonded. In the shoe insole of the present invention, the hot melt powder containing a polyamide component is interposed between the surface material and the intermediate material, between the layers of the intermediate material, and between the intermediate material and the backing material, respectively, and It is also possible to make a shoe insole by a method in which the obtained laminate is blown into a shoe insole shape by applying a high-frequency current, and at the same time, its outer peripheral edge is bonded. The shoes to which the shoe insole of the present invention can be applied include shoes for men, women and children, such as leather shoes for commuting, commuting to school, pumps, sandals, boots, walking shoes, athletic shoes, sneakers and the like. It can be used for various general shoes without any particular limitation. Further, the shoe insole of the present invention can be used by inserting it into the shoe, or as a material for the shoe, directly as an insole when manufacturing the shoe. In this case, in addition to the general shoes described above, sandals without sandals, sandals, slippers and the like can be applied. As described above, the shoe insole according to the present invention has almost no possibility that the emission of negative ions caused by the use of tourmaline is hindered due to its structure. Therefore, the negative ions act effectively on the soles of the feet, so, for example, negative ions from tourmaline are effectively absorbed into the body from the soles of the feet, making the blood weakly alkaline, adjusting the physical condition, and also expected to be effective against coldness etc. . Furthermore, the growth of bacteria causing odor is suppressed by negative ions, and the deodorizing effect is high. Hereinafter, embodiments of the present invention will be described with reference to the drawings. Example 1 FIG. 1A shows a front view of the surface of a shoe insole 1 of the present embodiment, FIG. 1B shows a back view of the shoe insole 1, and FIG. FIG. As shown in these figures, the shoe insole 1 of the present embodiment is manufactured by a method of fusing a laminate having a basic structure of five layers into a shoe insole shape, and bonding and integrating the outer peripheral edge 2 thereof. As is clear from FIG. 2, the shoe insole 1 of the present embodiment is obtained by laminating a front fabric 3, a back fabric 4, a first intermediate material 5, a second intermediate material 6, and a third intermediate material 7. It has a five-layer structure. In the present embodiment, a jersey woven fabric of polyester fiber having excellent hygroscopicity (texture is enlarged and shown in an enlarged view X of FIG. 1) is used as the front fabric 3, It uses a highly divergent Krehalon honeycomb woven fabric (the texture is enlarged and shown in the enlarged view Y in Figure 1). Further, as the first intermediate material 5 and the third intermediate material 7, a crehalon screen-patterned woven fabric is used. FIG. 3 shows the second intermediate member 6. The second intermediate member 6 is coated with a coating liquid obtained by mixing an acrylic resin with a solvent using a finely powdered tourmaline as a binder on the surface of the polyester nonwoven fabric 8. A product (trade name: Tolmarex) formed by coating and drying is used. As can be seen from FIG. 3, in the present invention, the coating liquid is applied on the surface of the polyester nonwoven fabric 8 such that the stripes are spaced at a constant interval, thereby forming coating stripes 9 respectively. As described above, in this embodiment, since tourmaline is adhered to the surface of the polyester nonwoven fabric 8, there is a low possibility that the generated nonionic ions are diverged in the sole direction by the polyester nonwoven fabric 8 itself. Further, the surface cloth 3 and the first intermediate material 5 existing between the sole of the foot and the second intermediate material 6 having tourmaline when worn are both made of a woven fabric having a very good air permeability. Therefore, the emitted negative ions of tourmaline effectively act on the sole without being hindered. Further, the shoe insole 1 has a very thin structure of about 2 to 4 mm in thickness despite the laminate. Therefore, even when the shoe is laid on the midsole of the shoe, the shoe does not feel extremely cramped, and the comfort is very good. [0013] The shoe insole according to the present invention uses, as a second intermediate material, a polyester nonwoven fabric having a mixture of tourmaline and a binder adhered to the surface thereof. Therefore, there is a low possibility that the diffusion of the negative ions from the tourmaline is hindered by the intermediate material or the like. In particular, since the outer fabric and the first intermediate material existing between the sole and the second intermediate material are made of a woven fabric having extremely good air permeability, the generated negative ions are effective without being hindered. It can act on the sole of the foot.
