Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a completely waterproof shoe having moisture permeability. 2. Description of the Related Art A completely waterproof shoe that prevents water from entering is generally provided with a waterproof inner formed by sewing a waterproof sheet in a bag shape surrounding a foot on a foot contact portion. The outer shell is attached so as to cover the waterproof inner, and the entire structure is formed in a double structure. In order to prevent water from entering the sewn portion, the waterproof inner is coated or dipped with a coating agent, an adhesive, or the like, and subjected to a sealing treatment. In order to prevent the inside of the shoe from getting wet, a waterproof film having moisture permeability is used as the material of the waterproof inner. However, a waterproof film or a moisture-permeable waterproof film alone is soft, low in strength, easy to cut, and sticky. In order to cover those disadvantages, a tricot cloth or the like is laminated on the film. In addition, in order to have a feeling of fitting to feet, heat retention, strength, cushioning, etc., a sheet obtained by further laminating a backing material via urethane foam on the tricot cloth side of the above laminate is a waterproof sheet for a waterproof inner. It was used as. This took such measures so as not to impair the performance of the film. In the conventional waterproof inner, the waterproof film is formed so as to be positioned at the outermost outermost surface of the inner in order to give top priority to waterproofness. And when it was installed inside the upper shell, the inner side of the upper shell and the surface of the waterproof inner were bonded and attached. When the waterproof inner is attached to the inside of the shoe, the surface of the waterproof inner and the inner surface of the upper are partially adhered and fixed with an adhesive or the like. In this case, the mounting position of the waterproof inner may be shifted. In such a case, the portion where the waterproof inner is once adhered is peeled off, the shifted mounting position is corrected, and then the waterproof inner is bonded again. [0006] However, when the portion which has been once adhered with the adhesive is to be peeled off, the waterproof film on the surface of the waterproof inner surface is so thin that the waterproof film is torn immediately. Care must be taken, and there is a problem that workability is poor. Also, if the waterproof inner is attached to the shoe with the position shifted, the gap between the upper shell and the waterproof inner will cause wrinkles, which will adversely affect the appearance of the shoe. The present invention has been made to solve the above-mentioned drawbacks of the prior art, and it is easy to mount a waterproof inner, has excellent workability at the time of mounting, and has a wrinkle caused by a displacement of the waterproof inner. It is an object of the present invention to provide a waterproof shoe free from occurrence and other problems. [0008] The present invention is a waterproof shoe having a double structure consisting of an upper shell and a waterproof inner located inside the upper, and the waterproof inner comprises a fiber material and a waterproof film. A waterproof shoe comprising at least two layers directly laminated, wherein the waterproof inner is partially adhesively bonded at a plurality of portions to the inner surface of the upper surface on the fiber material side. , And the gist. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a waterproof shoe according to the present invention has a double structure comprising an upper shell 1 and a waterproof inner 2 located inside thereof. Furthermore, the waterproof shoe of the embodiment shown in FIG.
It has an insole 3 and an outsole 4. In the present invention, the waterproof inner 2 is formed according to the shape of the foot, and has at least a fiber material 21 and a waterproof film 22 as shown in FIG.
And the waterproof film 22 are laminated so as to be in direct contact with each other. [0010] Further, as shown in FIG. 2, the waterproof inner 2 is adhered to the upper 1 by providing adhesives 5a, 5b, 5c, 5d on the inner surface of the upper 1 on the fibrous material 21 side. To
Partially bonded at multiple sites. Ie waterproof inner 2
Is loosely bonded to the upper shell 1 without completely bonding it. As shown in FIG. 3, the waterproof inner 2 is formed by using an inner laminated sheet 200 in which a fibrous material 21, a waterproof film 22, an elastic material 23, and a backing material 24 are laminated in this order, so as to conform to the foot shape. It is formed in a bag shape. The present invention provides a waterproof inner 2
A waterproof film 22 is disposed inside the inner and the fibrous material 21 is formed so as to be exposed on the surface.
A significant feature is that the fiber material 21 and the inner surface of the front shell 1 are partially adhered to each other to form a waterproof shoe. As the fibrous material 21, knitted fabric, woven fabric, non-woven fabric, or the like is used. For example, fabric materials such as taffeta, twill, lip, satin weave, circular knit, warp knit, sheet knit, tricot cloth, tricot half and the like, and elastic fiber knit are used. It is preferable to use a knitted fabric because of its elasticity. As the waterproof film 22, a resin film formed of a resin having a moisture-permeable and waterproof function is preferably used. Such resin film, the amount of moisture permeation is 5000g / m 2 · day or more, further preferably a 8000~20000g / m 2 · day. The preferred elongation of the waterproof film 22 is 0 to 3
00%, preferably 20-150%. Examples of the waterproof film 22 include a polyurethane resin film such as a polyether-based polyurethane and a polyester-based polyurethane. In a polyether-based polyurethane resin film, moisture permeability can be adjusted by adjusting the content of oxyethylene groups in the resin. The thickness of the waterproof film 22 is preferably 5 to 300 μm. As the elastic material 23, an elastic material having air permeability is used, and for example, a porous material such as polyurethane foam is preferable. The thickness of the elastic member 23 is usually 0.1 to 10.0 mm, preferably 0.5 to 5.0 mm. Since the backing material 24 is located at a portion in contact with the foot inside the shoe, a comfortable cloth material is used. The backing material 24 is a woven fabric, a knitted fabric, or a nonwoven fabric, for example, a French pile, a non-brushed tricot material, rayon, or the like. The waterproof inner 2 is formed by laminating a fibrous material 21, a waterproof film 22, an elastic material 23, and a backing material 24 in this order to produce an inner laminated sheet 200. For example, the inner laminated sheet 200 is formed into a shoe shape. After cutting and sewing into a predetermined shape corresponding to the above, the seam (perforation) is subjected to waterproof treatment.
As a method for waterproofing the perforations of the waterproof inner 2, dipping of latex, water-based, or solvent-based glue, brush coating, waterproof tape attachment, or the like can be used. As shown in FIG. 4, for example, as shown in FIG.
The laminated body 20 and the backing cloth material 24 are
It can be obtained by laminating on both front and back surfaces and integrating them. When the elastic material 23 is a polyurethane foam, the front and back surfaces of the polyurethane foam are instantaneously melted by flame in a so-called frame laminating method, and the laminate 20 and the backing cloth material 24 are bonded together, without impairing the moisture permeability of the waterproof film 22. Can be integrated. As a means for laminating the waterproof film 22 and the fiber material 21, a heat fusion method, an adhesion method using an adhesive, or the like can be used. Examples of the heat fusion method include a method of thermocompression bonding the waterproof film 22 to the fiber material 21 and a coating method of directly pressing the extruded molten resin to the fiber material 21 in a fluid state. Also, as the bonding method, (a) using a gravure roll or the like for the waterproof film 22, dot-like, stripe-like,
Apply adhesive in a pattern such as mesh or grid,
A method of bonding the fibrous material 21 via the adhesive, (b) a method of spray-coating the adhesive to the fibrous material 21 or the waterproof film 22 and pressing both, (c) a dot shape, a stripe shape, a mesh shape, Alternatively, there is a method in which a hot-melt type adhesive formed in a lattice pattern is sandwiched between the fiber material 21 and the waterproof film 22 and bonded by thermocompression. As the adhesive, known adhesives such as urethane, nylon, and ester are used. This lamination may be entirely, partially, such as a dot shape or a stripe shape, or may be any,
It is desirable to adjust the bonding area to be in the range of 2 to 90%, preferably 20 to 80% of the total contact area. In the present invention, when the laminate 20 is laminated on the elastic material 23, as shown in FIGS.
It will adhere to 23. In particular, when the elastic material 23 is formed of a porous body such as a polyurethane foam, lamination on the waterproof film 22 has an advantage that bonding can be strengthened rather than fiber material 21. The lamination of the laminate 20 and the elastic material 23
As described above, frame lamination may be used, and as in the case of laminating the waterproof film 22 and the fibrous material 23, either a heat fusion method or an adhesive method may be used. The inner laminated sheet laminated as described above preferably has a moisture permeability of 500 to 50,000 g / m 2 · day, more preferably 3,000 to 50,000 g / m 2 · day. In the waterproof shoe of the present invention, a waterproof inner 2 formed in a bag shape is adhered to the upper shell 1 using the above-described inner laminated sheet to form a shell, and the inner sole 3 and the outer sole 4 are formed on the upper. It can be obtained by attaching etc. When partially waterproofing the waterproof inner 2 to the outer shell 1 or the like, the bonding site using the adhesive 5 (5a, 5b, 5c, 5d) or the like is not limited. The pressure-sensitive adhesive 5 used for this bonding is not particularly limited as long as it can be bonded by applying pressure, and a rubber-based or acrylic-based pressure-sensitive adhesive, a double-sided pressure-sensitive adhesive tape, various adhesives, and the like can be used. In the present invention, the term "adhesive bonding" of the waterproof inner to the outer shell refers to an adhesive state in which the two can be peeled off and re-adhered at the initial stage of bonding, and thereafter, in a broad sense including adhesive. Shall be referred to. The location where the adhesive 5 is provided is not particularly limited. However, it is preferable to provide the adhesive 5 at a location where the waterproof inner 2 is likely to be displaced from the upper shell 1 when the shoe is hanged, or at a bent location for wear. The blade 1 is obtained by cutting into a predetermined blade material shape using artificial leather, synthetic leather, or the like, and then sewing.
It is preferable to apply a waterproof tape to the perforations to prevent water from entering the inside of the upper shell. Further, as a material of the upper shell, a material used for clothing may be used. As a preferable material, a material whose surface is subjected to a strong water repellent treatment can be mentioned, and good waterproofness can be obtained as a completely waterproof shoe. As shown in FIG. 2, an insole material 6 can be adhered to the inside of the waterproof inner 2 of the waterproof shoe thus obtained, as shown in FIG. Although the handmade manufacturing method has been described as a method for manufacturing the shoe itself, a known method such as an injection manufacturing method, a total rubber manufacturing method, and a slash manufacturing method can be used. Embodiments of the present invention will be described below. (A) Preparation of waterproof inner A waterproof film of 10 μm thickness on one side of nylon tricot half (Diaplex D9900: manufactured by Diaplex)
Were laminated to obtain a laminate. A waterproof film side of the laminate was frame-laminated on one side of a polyurethane foam having a thickness of 3 mm, and a polyester French pile was frame-laminated on the other side of the polyurethane foam at the same time to obtain a moisture-permeable waterproof sheet for a waterproof inner. . Cut the above moisture-permeable waterproof sheet according to the shape of the shoe, sew it so that the nylon tricot half becomes the outer surface, apply water-based latex paste (natural rubber type) to the perforations, fill in the perforations and seal the waterproof inner. Obtained. (A) Fabrication of upper shell After cutting into a predetermined upper shape using brushed artificial leather, sewing was performed to obtain an upper shell. Waterproof tape was applied to the perforations to perform waterproof treatment on the outer shell. (C) Preparation of the shell material The waterproof inner was partially adhered to the inner side of the shell using an adhesive tape. The toe, both sides, and the heel part were obtained as the bonded part. (D) Assembling of shoes The above-mentioned upper material is hung on the predetermined last, the insole material is arranged on the last bottom surface, the back side of the upper material and the insole material are adhered and fixed all around using rubber glue, and The bottom was bonded and fixed via rubber glue. Finally, the last was removed and shoes were obtained. A gap occurred between the toe and the inner foot between the outer shell of the shell and the waterproof inner, causing wrinkles. For this reason, the waterproof inner was peeled off once and the gap was corrected, and then the pieces were bonded again to complete a wrinkle-free shoe. At this time, the adhesive portion of the waterproof inner was not destroyed. A 24-hour water immersion test was performed on the obtained shoes. As a result, no water entered from the outside of the shoes. The waterproof shoe according to the present invention has a double structure consisting of an upper shell and a waterproof inner located inside the upper, and the waterproof inner has at least a fiber material and a waterproof film. It is constructed by directly laminating layers, and by adopting a structure in which the waterproof inner is partially adhesively bonded to the inner surface of the upper surface on the fiber material surface in multiple parts, the waterproof inner is When the position is shifted, it is easy to peel off the waterproof inner from the outer shell, fix the position, and adhere again, so that the shifted portion can be prevented from wrinkling. When the waterproof inner is peeled from the outer shell, since the waterproof inner film to be adhered to the upper is made of a fiber material and the tear-resistant waterproof film is located inside and is not exposed on the surface in contact with the upper. In addition, the waterproof film is not damaged as in the prior art, and the workability during shoemaking is excellent. Also, compared to the case where a conventional waterproof inner film having a waterproof film exposed on the surface is used, there is no fear that the waterproof film is broken by movement such as bending or rubbing, and the performance is good for long-term use. A waterproof shoe is obtained.
