Abstract

(57) [Abstract] [Purpose] To improve the feeling of stuffiness in shoes in which the upper material of the upper part is formed using synthetic leather. [Structure] A synthetic leather material 3 formed by processing and forming a large number of fine holes 4 having a diameter of about 0.1 mm or less is polymerized and pasted on a back surface side of a synthetic leather material 3 having both breathability and waterproofness. And constitutes the instep covering 2.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to an instep material that constitutes an upper (upper) portion of a shoe.

[0002]

[Prior Art]

 Traditionally, shoes have been manufactured that use synthetic leather for the instep material that constitutes the upper part.The synthetic leather has a structure called microporous structure, and it has both moisture permeability and waterproofness. Are also being developed.

[0003]

[Problems to be solved by the device]

 A shoe manufactured by using synthetic leather with a breathable film as the upper material has breathability but little breathability. For this reason, conventional shoes that use synthetic leather for the instep material tend to get wet inside the shoes due to the buildup of moisture inside the shoes, especially on humid days such as rainy days. There are drawbacks.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a shoe instep material having both breathability and waterproofness.

[0005]

[Means for Solving the Problems]

 In this invention, a synthetic leather material is used which has a large number of fine pores dispersed on the entire surface, for example, fine pores having a diameter of about 0.1 mm or less. In addition, a cloth material having both waterproof property was polymerized and adhered to form a shoe instep material.

The above instep material has a large number of fine holes formed in the synthetic leather material, and the cloth material polymerized and attached to the synthetic leather material is breathable and waterproof. It will be provided with breathability and waterproofness as a bonded product. The fine pores formed in the synthetic leather material that will form the outer surface of the upper part of the shoe are, for example, fine with a diameter of around 0.1 mm or less, so that they have almost no external appearance. It does not adhere to

【Example】

 Preferred embodiments of the present invention will be described below with reference to the drawings.

FIG. 2 is a plan view of the shoe, and FIG. 1 shows an enlarged vertical sectional view of a circled portion A of the upper portion 1 of the shoe. As shown in FIG. 1, an instep material 2 constituting the upper part 1 of this shoe has a cloth material 5 on the back side of a synthetic leather material 3 formed by processing a large number of fine holes 4 dispersed over the entire surface. It is formed by stacking and adhering.

The size of the fine holes 4 formed in the synthetic leather material 2 is such that the appearance is barely noticeable, and for example, the diameter is about 0.1 mm or less. In this case, it is not always necessary to make the sizes and shapes of the fine holes 4 uniform, and the fine holes 4 of various sizes and shapes may be formed. Further, the number of the fine holes 4 is set to be necessary and sufficient for providing the synthetic leather material 3 with air permeability, and is related to the size of the fine holes 4, for example, 50 to 200 pieces / cm. Set to about ² .

On the other hand, as the cloth material 5, a cloth having both breathability and waterproofness is used. A non-woven fabric that has been subjected to a water-repellent finish is suitable as such a cloth, and one specific example thereof is a myway in which a non-woven fabric made of polyester ultrafine fibers is subjected to a water-repellent finish using Teflon. Tex (trade name of Foot Techno Co., Ltd.) (air permeability: 10 cc / cm ² / sec, water pressure resistance: 500 mmH ₂ O) and the like are used. It is also possible to use a cloth woven so as to withstand a water pressure of, for example, about 500 mmH ₂ O by appropriately selecting the kind and thickness of the thread to be used, the density of the thread and the thickness of the cloth.

Then, the above-mentioned synthetic leather material 3 and the cloth material 5 are superposed on each other, and the two materials are bonded together by a method in which the air permeability as a polymerized adhesive is not significantly impaired. For example, the synthetic leather material 3 and the cloth material 3 may be formed by point-bonding with an adhesive, grid-bonding with a melt-bonding film, or melt-bonding with a sheet-shaped urethane foam. 5 and 5 are polymerized and attached to form the instep covering 2. Then, the instep material 2 thus formed is used to form a part or the whole of the upper portion 1 to manufacture a shoe.

The instep material of the present invention is configured as described above, but the scope of the present invention is not limited by the above description and the contents of the drawings, and various modifications can be included without departing from the scope of the invention. .. For example, in the above embodiment, the synthetic leather material and the cloth material are polymerized and bonded to form the instep material. However, for the purpose of reinforcement or other purposes, the space between the synthetic leather material and the cloth material or the back side of the cloth material is Alternatively, a reinforcing material made of a material that does not impair the air permeability is inserted or overlapped on both of them, and they are attached by a method that does not impair the air permeability so that the instep material is formed. May be.

[Effect of the device]

 Since the present invention is constructed and operates as described above, a shoe manufactured by constructing a part or all of the upper part by using the instep material of the present invention will not Because the moist air of the air permeates the instep material and is discharged to the outside of the shoe, the feeling of stuffiness is greatly improved compared to conventional shoes using synthetic leather for the instep material, especially on rainy days. On such a humid day, comfort is significantly improved compared to conventional ones.
