Description

[Detailed description of the invention] [Industrial application field] The invention provides a comfortable shoe opening that has excellent sweat and moisture absorption properties, reduces wetting and stuffiness phenomena, is lightweight, and has excellent abrasion resistance. This relates to boots that are higher than the ankle.

[Conventional technology]

Rubber boots with collars that are higher than the ankle often have a lining material affixed to the inner surface to provide comfort, cold protection, sweat absorption, etc., but there are various types depending on the purpose. A soft lining material is applied. Among them, boots that use a single layer of moisture-absorbing fabric or water-permeable fabric and a porous foam material attached to the back side, that is, the outer layer of the boots, are used to provide sweat-absorbing properties. etc. are known. In addition, as a means for imparting sweat absorption properties to general footwear, a porous foam material 3 such as polyurethane and a non-woven material on the side that comes into contact with the foot are used as shown in FIG. A double-layered knitted or double-layered knitted fabric or woven fabric 2' made of hygroscopic yarn and a hygroscopic yarn is attached to the back side of the outer layer 1 of boots, and the double-layered knitted or double-layered knitted or woven fabric 2' is made of hygroscopic yarn and hygroscopic yarn. ', a thick hygroscopic thread 4 is used on the porous foam material 3 side, and a non-hygroscopic thread 4 is used on the opposite layer, that is, the layer that comes into contact with the foot. Footwear and the like are known in which sweat-absorbing properties are imparted using thin threads 5.

[Problem that the invention attempts to solve]

As mentioned above, there are various methods for imparting sweat absorption properties, but especially boots with a non-water-absorbing rubber layer or synthetic resin layer and a collar that is higher than the ankle, such as work boots. For boots that do not require much heat retention and are worn during the summer months when sweating is likely, the conventional methods of imparting sweat absorption properties as described above have had various problems.

In other words, a structure in which a single layer of moisture-absorbing fabric is attached to the back side of a surface layer consisting of an impermeable rubber layer or synthetic resin layer quickly becomes sticky, and furthermore, if the back side is made of porous foam material and its feet touch Boots that use lining material with water-permeable fabric attached to the contact side,
In boots using sweat-absorbing properties as shown in Utility Model Publication No. 59-13849, the porous foam material has heat-retaining properties even though it has a certain degree of sweat-absorbing and water-retaining function. However, there is a fundamental problem with boots such as work boots that are worn even in the summer, where it is desirable to eliminate this characteristic.Furthermore, porous foam materials have a sweat absorption and water retention function only in the local area where sweat is generated. However, there is a problem in that the performance of dispersing sweat-absorbed moisture to the surrounding area is poor, and that after a certain amount of sweat absorption, a sticky phenomenon occurs in the area.

[Means for solving problems]

As a result of intensive studies to solve the problem of sweat absorption of conventional rain boots, the present inventor used a knitted fabric made of two or more synthetic fibers with different single yarn finenesses. A surface made of yarn with a small single filament fineness is attached to the outer layer side of the boots, and the surface made of a yarn with a small single filament fineness is attached to the outer layer side of the boots. If the surface is on the inside of the boots, there will be no wetting phenomenon even when the knitted fabric is attached directly to the back of the outer layer consisting of a water-impermeable rubber layer or synthetic resin layer, and it has excellent sweat absorption and abrasion resistance. He discovered that superior boots could be obtained and completed this invention.

That is, the present invention provides boots with a collar that is above the ankle, in which a lining material is attached to the back side of an outer layer made of a rubber layer or a synthetic resin layer, and the lining material is made of synthetic fibers with different single yarn finenesses. The fabric is knitted so that yarns having the same single yarn fineness are located on the same side, and the side consisting of yarns having a small single yarn fineness is attached to the back side of the surface layer. It is about boots that are worn.

Hereinafter, embodiments of boots according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a side view of one embodiment of the boots according to the present invention, and FIG. 2 is an enlarged cross-sectional explanatory view showing the positional relationship between the outer layer and the lining material of the boots according to the present invention.

In the drawings, reference numeral 1 denotes the outer layer of a boot whose opening is made of a rubber layer or a synthetic resin layer such as soft polyvinyl chloride and is higher than the ankle. 2 is composed of synthetic fiber yarns such as nylon fibers and polyester fibers with different single filament finenesses directly attached to the back side of the surface layer 1, and is knitted so that the yarns with the same single filament finenesses are located on the same surface. The lining material is made of a knitted fabric, and its structure is as shown in FIG. The surface 2b made of yarn with a large fineness is located on the side that comes into contact with the foot.

In the present invention, as described above, the surface 2a of the lining material 2 made of yarns with a small single filament fineness is attached to the surface layer 1, and the side 2a made of yarns with a large single filament fineness is attached to the surface layer 1.
b is required to be located on the side that comes into contact with the foot. With this configuration, excellent sweat absorption is exhibited, and the lining material 2 is formed on the non-water permeable surface layer 1. Even if it is directly attached, its sweat absorption properties are not impaired.

In the present invention, it is preferable that the difference in single yarn fineness is 1.5 times or more for the yarn with a large single yarn fineness as compared to the yarn with a small single yarn fineness, and more preferably a difference of 2 times or more. Further, from the viewpoint of abrasion resistance, the single yarn fineness of the yarn on the side that comes into contact with the foot, that is, the yarn with a large single yarn fineness, is preferably 2 deniers or more, preferably 3 deniers or more, and the yarn on the surface layer 1 side It is preferable that the single yarn fineness of the yarn, that is, the yarn having a small single yarn fineness, is 1 denier or more from the viewpoint of sweat absorption and strength. The number of single yarns of such synthetic fiber yarns with different single yarn finenesses is preferably 10 or more, and especially for yarns with small single yarn finenesses, it is preferable to have 30 or more yarns to achieve the purpose of the present invention. preferred above.

The knitting structure of the knitted fabric is not particularly limited, and either single knitted fabric or double knitted fabric can be applied, but single knitted fabric has a simpler structure and is preferable in terms of wear resistance, but double knitted fabric Since it is thicker, it is preferable in terms of sweat absorption, but it is not preferable for use in summer because it has high heat retention.

[Effect]

In the rain boots according to the present invention having the above-mentioned configuration, sweat permeates through the surface 2b made of yarns with a large single filament fineness and is absorbed into the surface 2a made of yarns with a small single filament fineness. However, this is not because the yarn itself with a small single filament fineness is a hygroscopic type of fiber, but because it is formed between the single filaments of the yarn constituting the surface 2b consisting of yarns with a large single filament fineness. Since the gaps formed between the single threads of the yarns constituting the surface 2a, which are made of yarns with a smaller fineness than the gaps between the yarns, are very small, the sweat absorption is improved due to the large capillary phenomenon of this very small gap. This is because it is given. In this way, sweat is absorbed by the surface 2a made of yarns with small fineness,
Since this surface 2a consisting of yarns with small single filament fineness is made up of many single filaments, the absorbed sweat does not stay only in the absorbed part, but is transferred to the yarns by the large capillary phenomenon. As a result, even if the backing material 2 is directly attached to the water-impermeable surface layer 1, stuffiness and wetting phenomena are eliminated. Furthermore, while the boots are not being worn, the absorbed sweat passes through the surface 2b made of yarn with a large single yarn fineness and is released to the outside, so the wearer will not feel wet or stuffy. There isn't.

[Effect of idea]

The boots according to the present invention as described in detail above have a lining material knitted from synthetic fiber yarns having different finenesses of single yarns attached to the back side of the outer layer consisting of a rubber layer or a synthetic resin layer. The surface made of threads with a small fineness is located on the surface layer side, and the surface made of threads with a large single filament density is located on the side that comes into contact with the foot, so the sweat generated from the feet is Sweat is absorbed and transferred from the surface made of yarns with a large single filament fineness to the surface made of yarns with a small single filament fineness, and the absorbed sweat is widely diffused within the yarns with a small single filament fineness. Even though the surface layer is made of a water-impermeable rubber layer or synthetic resin layer, the surface that comes into contact with the foot does not get stuffy or wet, and is always kept dry.

In addition, the surface that comes into contact with the foot is made of synthetic fibers with a high fineness, so it has excellent abrasion resistance, and it does not require the addition of porous foam or other hygroscopic materials. Since they have sufficient sweat absorbing properties, they can provide thin and light boots suitable for wearing in summer, etc., and can be made at low cost, so they have great practical value.
