Description

Detailed Description of the Invention (1) Technical field The present invention provides a shoe insole that has a thermal insulation effect in winter, does not swell, allows air to circulate through the sole of the foot, and has a good feel. and its manufacturing method.

(2) Background Art In the past, various shoe insoles with effects such as breathability and odor absorption have been proposed. Japanese Patent Publication No. 49-48024 discloses a shoe insole formed by sequentially overlapping an intermediate woven fabric B and a finely woven outer woven fabric made of resin monofilament and welding the peripheral edges thereof, and a method for manufacturing the same.

In addition to the above-mentioned shoe insoles, we have added the two functions of odor absorption and anti-mold, by adhering spherical activated carbon to vinylidene chloride-based synthetic resin short fiber nonwoven fabric using latex containing an anti-mold solution and having open cells. No) C is made, and the coarse mesh woven fabric A, the honeycomb intermediate woven fabric B, and the finely woven surface woven fabric are woven into woven fabric A, intermediate woven fabric B, sheet C, and the surface woven fabric. A deodorizing and mold-proof shoe insole made by overlapping and welding the peripheral edges in this order and a method for manufacturing the same are disclosed in Japanese Patent Laid-Open No. 54-22252.

For example, a coarse mesh woven fabric A made of vinylidene chloride-based synthetic resin monofilament, a honeycomb interwoven fabric B made of the resin monofilament, a non-woven fabric made of the resin and/or vinyl chloride-based synthetic resin short fibers, A sheet s coated with a mixed latex containing activated carbon powder, copper powder, and magnetic powder and then heated, and a surface woven fabric made of the resin monofilament are sequentially superimposed,
A shoe insole made by welding the peripheral edge, made of latex 10
The Mk ratio of activated carbon powder, copper powder, and magnetic powder to 0 is lO~50.10~5o11oo~4o, respectively.

The components of the latex used in the above mixed latex are, in weight ratio, 0.5 to 1.5 sodium lauryl sulfate and 0.5 to 1 sulfur per 100 parts of nitrobutyl latex.
．． 5. Zinc white 0.5-1.5, vulcanization accelerator 0.5-1.
5. A shoe insole containing anti-aging agents 1 to 3 and a method for producing the same are also disclosed in Japanese Patent Publication No. 18204/1983.

(3) Purpose The above-mentioned insoles are preferably used in the spring, summer, and autumn seasons due to the characteristics of the woven fabrics or sheets that make up each insole, but the insulation and heat retention effect in the winter is not necessarily sufficient. It was indescribable.

Therefore, the present inventors conducted studies to obtain a shoe insole that has a thermal insulation effect even in winter, does not get stuffy, allows air to circulate in the sole of the foot, and has a good feel.
By using fabric coated with aluminum vapor deposition on the back of the shoe insole, and then laminating a top sheet with good texture on the surface and welding the periphery, it was possible to obtain an extremely good shoe insole, and the present invention was completed. It is.

(4) In other words, the insole of the present invention comprises a fabric AN coated with aluminum vapor deposition, a honeycomb intermediate woven fabric B made of vinyl chloride-based synthetic resin monofilament, and a non-woven fabric made of the resin and/or vinyl chloride-based synthetic resin short fibers. A sheet S coated with mixed latex mixed with activated carbon powder and copper powder and then heated, a coarse reticulated woven fabric A made of vinylidene chloride synthetic resin monofilament, and a top sheet V were prepared so that the aluminum vapor-deposited surface was the outer surface. cJ@This is an insole made by overlapping and welding the periphery.

The aluminum-deposited fabric constituting the shoe insole of the present invention is, for example, a thin nylon knitted fabric (stockinette, knit).
Alternatively, it is a thin nylon nonwoven fabric that can provide a heat reflecting effect due to aluminum vapor deposition.

In addition, from the viewpoint of wearing comfort, it is preferable that the front sheet v has a relatively fluffy feel, such as boa, tricot (particularly nylon tricot), velveteen (corten), etc.
etc.

(5) Examples Hereinafter, the present invention will be described in detail with reference to the drawings. The shoe insole of the present invention includes copper powder, copper powder, A sheet S is prepared by applying a mixed latex mixed with charcoal powder and then heat-treated, and as shown in FIGS. S1 The coarse mesh woven fabric A, top sheet V
2. In Fig. 1, a indicates q welded areas other than the periphery (for regulating the relative movement of each laminated material). Indicates low

Next, one step of the method for manufacturing the shoe insole of the present invention will be explained with reference to FIG. After applying the mixed latex to the long aluminum vapor-deposited fabric AN, the honeycomb intermediate woven fabric B, and the non-woven fabric and treating it, the fabric S, the coarse mesh woven fabric A, and the top sheet v,
Fabric AN Intermediate woven fabric B, sheet S, woven fabric A, and front woven fabric A are laminated in this order as a laminate 5 through a row 210 and then intermittently along the upper surface of the lower electrode 3 of the flat panelist by a tensioning device (not shown). 1 and between the laminate 5 and the flat lower electrode 3. is a paper with a thickness of 0.02 to 0 on a paper with a thickness of 01 to 0.5
．． Insulating buffer 1 made of laminated polyester film
The material 4 is passed through rollers 11.12, and the upper surface ζ of the laminate 5 is passed through rollers 13.14 to a thickness of 0.01~
Layer the polyester film 6 of 0.02 tone,
These three parts are moved intermittently at the same speed, and the upper electrode 7 in the shape of the outer periphery of a shoe insole is lowered to the lower electrode 3. is crimped between both electrodes, and a high-frequency current is passed between both electrodes 3 and 7 to weld the peripheral edge of the laminate. If desired, multiple cutting lines corresponding to each size of the foot are welded. After that, it is punched out.

(6) Effects The shoe insole of the present invention has the above-described laminated structure, so that the following excellent effects can be exhibited due to the characteristics of each laminated material. In other words, a) The presence of aluminum vapor-deposited fabric provides insulation properties, making the soles of the feet less susceptible to temperature changes directly beneath the shoes when worn, thus improving comfort. Contribute.

The aluminum-deposited fabric is located on the backmost side of the insole, and when worn, between the sole of the foot and the fabric, there is a vinylidene chloride-based fabric in Woven Fabrics A, B, and %. Because of this, it has good breathability and allows heat to escape from the area near the soles of the feet, so the soles of the feet do not get stuffy.

7. Aluminum, which contributes to heat insulation, is vapor-deposited on the fabric, so the two are strongly integrated, and aluminum is resistant to peeling, so it has excellent durability.

→ The presence of vinylidene chloride-based woven fabrics, particularly woven fabrics A and B, provides excellent elasticity and contributes to improved comfort.

71 Since the sheet contains activated carbon, it can absorb bad odors generated inside shoes, and since it contains copper powder, it can prevent athlete's foot from occurring.

F) Since the top sheet is present in a position that directly contacts the sole of the foot, that is, on the outermost side, it provides good feel on the sole of the foot, thus contributing to improved comfort.

g) By forming a plurality of cutting lines corresponding to each foot size, the size of the insole can be changed using the cutting lines depending on the shoe in which the insole is used, and therefore, Versatility can be widened.

In addition, in this method of manufacturing shoe insoles, due to the presence of the aluminum evaporated surface, it is impossible to manufacture the insole by welding and cutting in one operation, but since the welding C-shaped part can be created by high frequency, punching must be performed separately. ? This allows for more efficient manufacturing.

As described above, the shoe insole of the present invention has a heat-insulating effect even in winter, does not get stuffy due to air circulation in the sole, and has a good feel.
