[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shoe insole, particularly a shoe insole having a high deodorant effect, a blood circulation promoting property, a heat retaining property, a molding simplicity and a walking stability of the shoe.

[0002]

[Prior Art]

 Conventionally, as an insole of shoes, one containing activated carbon having a deodorizing effect is known (Japanese Utility Model Publication No. 57-12885, Japanese Utility Model Publication No. 58-32652, and Japanese Utility Model Publication No. 57-43849). Such). Further, as those having a blood circulation promoting effect, those having irregularities on the surface thereof are known (Japanese Utility Model Publication Nos. 57-45855 and 58-16647).

[0003]

[Problems to be solved by the device]

 However, the insole using the above activated carbon has a problem that the deodorant function deteriorates with the lapse of time, so that the product life is short. However, since it is pressed and worn when it is used, there is a problem that its function disappears due to changes over time.

The object of the present invention was devised to eliminate the above-mentioned drawbacks of the conventional products, and is excellent in deodorizing property and blood circulation promoting property even when there is a change over time, and further has high moldability. It provides shoe insoles.

[0005]

[Means for solving the problem]

 The present invention has been devised in view of the above, in which a breathable sealant layer is interposed between front and back fabrics woven with polypropylene expanded spread yarn as warp yarns, and magnetic pellets are scattered, This is an insole that is characterized in that the front and back are polymerized and fused with a sealant layer and can be cut into a foot shape.

The sealant layer in the present invention melts at a temperature lower than the melting point of the front and back to polymerize and fuse the front and back, and is a thermoplastic resin having a lower melting point than the front and back. I won't. In addition, the sealant layer must be a thermoplastic resin molded to enhance the air permeability so that the insole itself has air permeability. Thermoplastic resins satisfying such conditions include polyethylene, ethylene-vinyl acetate copolymer, and the like, and these resins can improve air permeability by being formed into a cross-laminated film, a woven fabric, and a nonwoven fabric. ..

Further, the magnetic pellet is formed into a pellet by combining fine particles of a conventionally known material such as ferrite that can be used as a permanent magnet and a synthetic resin as a carrier for the fine particles. .. It should be noted that the magnetic pellets are embedded in the insole of the shoe by being evenly distributed over the sealant layer, and exert their deodorizing effect and blood circulation promoting effect due to their magnetism. However, it is necessary for the pellets to be non-magnetized at the time of application, because the magnetism tends to solidify in one place and the particles cannot be evenly applied.

[0008]

[Action]

 According to the present invention, a breathable sealant layer is provided on a front or back fabric woven with polypropylene expanded spread yarn as warp and weft, and magnetizable pellets are dispersed on the sealant layer. A lining or surface is placed on the base, and the front and back are polymerized and fused with a sealant layer, and the pellets are magnetized to form a base material for the insole, and then the base material is cut into a foot shape. Form the insole.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the embodiments shown in the drawings. FIG. 1 is an explanatory view schematically showing an embodiment of an insole according to the present invention with a part thereof cut away, and FIG. 2 shows an embodiment of an insole according to the present invention. It is explanatory drawing which showed the cross section typically. FIG. 3 is an explanatory view schematically showing the manufacturing process of an embodiment of the insole according to the present invention.

As shown in FIGS. 1 and 2, the insole of the shoe of the present embodiment includes front and back linings 1 and 2 woven with polypropylene expanded spread yarn as warp and weft, and the front and back linings 1 and 2. It is composed of a sealant layer 3 interposed between the sealant layer 3 and the magnetic pellets 4 substantially uniformly dispersed between the sealant layer 3 and the outer material 1. Here, as the sealant layer 3, a commercially available cross-laminated film having low density polyethylene as a base material (manufactured by Nisseki Plastics Co., Ltd., trade name Nisseki split cloth) was used.

Further, the insole of this embodiment is manufactured as shown in FIG.

The outer material 1, the lining 2, and the sealant layer 3 wound around the base material supply rolls 5, 5 and 5 are fed between the hot melt rolls 7a and 7b, conveyed onto the hot melt rolls 7b and 7c, and thereafter. The film is wound around the winding roll 8. By transporting each of the base materials on the hot melt rolls 7a, 7b, 7c, the front and back linings 1 and 2 are polymerized and fused by the sealant layer 3. The inside of the apparatus is set to 150 ° C. for this polymerization fusion. This set temperature is set so that only the sealant layer 3 is melted without melting the front and back fabrics 1 and 2, and the melting point of polypropylene is around 170 ° C and the melting point of low density polyethylene is around 110 ° C. It is set in consideration of this.

Further, the magnetic pellets 4 which have not been magnetized are spread substantially uniformly from the pellet feeder 6 on the sealant layer 3 before the polymerization fusion, and the pellets 4 are magnetized by a magnetizer (not shown) after the polymerization fusion. To be done. Although not shown, the base material of the wound insole is cut into a foot shape to form an insole.

In this embodiment, the front and back fabrics 1 and 2 are woven using polypropylene expanded spread yarns as warp and weft yarns, and a sealant layer 3 made of a cross-laminated film is interposed between the front and back fabrics 1 and 2. Since it is worn, it has the effect that the insole of the shoe has high air permeability. In addition, since the front and back linings 1 and 2 are made of polypropylene expanded fiber and have a large surface area, they have the effect of high heat retention. Furthermore, the large surface area increases the contact area with shoes. The grip between the foot and the shoe is enhanced, and the walking stability is high. In addition, since the manufacturing process is basically polymerization and fusion of sheets, there is an effect that molding is easy. Furthermore, since the magnetic pellets 4 are substantially evenly dispersed between the sealant layer 3 and the outer material 1, even if the insoles of the shoes change over time, deodorant properties and blood circulation promoting properties can be maintained. Have.

[Effect of the device]

 In the present invention, a sealant layer having air permeability is interposed between the front and back fabrics woven with polypropylene expanded spread yarns as warp and weft yarns, and magnetic pellets are scattered to form the front and back fabrics with the sealant layer. It is polymer-fused and cut into a foot shape, which has the effects of high breathability, heat retention, walking stability, and ease of molding.In addition, it has deodorant and blood circulation promoting properties even with changes over time. It has a high effect.
