Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a laminate suitable for forming clothes (especially outerwear for outdoor use in cold weather).

[0002]

2. Description of the Related Art A cold weather outerwear is worn when performing outdoor sports or working outdoors during cold weather. In recent years, with respect to such outerwear, it is not enough to keep the heat of the human body warm with the outerwear. Instead, it is considered to attach a heating member to the jacket itself to warm the human body.

As such a jacket for heating, for example, a dedicated storage pocket is provided on the lining of the jacket and a so-called "disposable body warmer" is stored therein or a tank for storing fuel gas. It is known that the fuel gas is attached to a jacket and used as a heating member by oxidizing the fuel gas.

[0004]

However, in such conventional heating outerwear, the heating member is locally arranged in a part of the outerwear because of the weight, shape and size of the heating member. Inevitably, it does not effectively warm the entire upper body of the wearer. A person who wears such a conventional jacket often feels that the portion where the heating member is attached is locally hot and the other portion is cold.

In order to avoid such an inconvenience, it is conceivable to dispose a heating member on the entire outerwear, but this increases the weight of the entire outerwear, and due to the shape of the heating member and the like, Flexibility is also reduced, wearing comfort is poor, and the cost is high. Further, when fuel gas or the like is used, the structure becomes complicated, and it is necessary to take measures to prevent gas leakage and the like, and cost increase cannot be avoided.

[0006] An object of the present invention is to provide a laminated body suitable for constructing a jacket which is capable of efficiently heating the entire body and is excellent in economical efficiency, and a jacket using the same.

[0007]

A laminate of the invention 1 is a first layer having a surface heating element attached to the surface thereof, and two or more woven or knitted fabrics laminated on the surface of the first layer by a crossover yarn. And a second layer made of a woven or knitted fabric that is three-dimensionally connected.
In this laminate, the second layer made of a woven or knitted fabric having a predetermined three-dimensional structure forms an air layer in or between the second layer and the first layer. When the sheet heating element of the first layer, which is located in contact with the air layer, generates heat, the air layer effectively retains this heat in the entire layer.

The woven or knitted fabric, which constitutes the second layer and in which two or more woven and knitted fabrics are three-dimensionally connected by the thread, is the second
It is sufficient as long as it can form an air layer between itself and the first layer, for example, "double Russell", "double tricot knitting (single tricot knitting with a two-row needle bed tricot knitting machine. Heavy tissue) ”and the like.

The laminated body of the invention 2 is the laminated body of the invention 1 in which the first layer is made of a fiber structure surface-treated with a heat transfer material, and the planar heating element is attached to the surface thereof.

In this laminated body, the first layer to which the planar heating element is attached is made of a fiber structure subjected to a predetermined surface treatment, and conducts heat transferred from the planar heating element well to the entire laminated body. The radiant heat from the planar heating element is reflected to the surface side to effectively warm the air layer side.

Examples of the heat transfer material forming the first layer include metal and carbon. Examples of the fiber structure include fibers (yarns), woven fabrics, knitted fabrics, non-woven fabrics, and others in which urethane or the like is impregnated.
And as a concrete first layer, for example, metal, carbon, etc. plated or vapor-deposited on a fiber woven or knitted material, metal,
Examples thereof include metal fibers obtained by fiberizing carbon and the like, woven and knitted materials mixed-spun, interwoven, interwoven, and synthetic resin such as polyurethane impregnated with metal fibers and carbon fibers.

The laminated body of the invention 3 is the laminated body of the invention 1 or 2, and is a woven or knitted fabric which is laminated on the back surface side of the first layer and in which two or more woven and knitted fabrics are three-dimensionally connected by a thread. Further comprising a third layer consisting of In this stack, the third
The layer forms an air layer with the first layer on the back surface side to prevent heat from the planar heating element from escaping from the back surface side.

The laminate of the invention 4 is the laminate of the invention 3, wherein a heat insulating material is further laminated on the back surface side of the third layer. By additionally laminating a heat insulating material on the back surface side, the separation of the planar heating element from the back surface side can be more effectively suppressed. A laminate of invention 5 is the laminate of invention 3 or 4, wherein the first layer is removable from between the second layer and the third layer.

By removing the first layer to which the sheet heating element is attached, it is possible to prevent the sheet heating element from being damaged when the laminate is washed with water, for example. A layered product of an invention 6 is the layered product of any one of the inventions 1 to 5, and the planar heating element having a positive load resistance characteristic is a plurality of heating elements. The planar heating element of this laminate has a small plate shape, and the flexibility and flexibility of the laminate are not impaired even when the laminate is used for clothes. Further, the planar heating element composed of a heating element having a positive load resistance characteristic can change its self-resistance value according to the temperature, and for example, the heating temperature can be self-controlled in a temperature range of 10 to 40 ° C. In this case, the temperature range suitable for the human body can be automatically maintained without excessively increasing the temperature. Further, such a sheet heating element can be obtained relatively inexpensively,
It is also economical.

The surface cloth body of the garment may be made of a material different from that of the back cloth body, or may be made of the same material. And when it is composed of the same material, the outerwear may be made of one material.

In this garment, power is supplied to the planar heating element from a power supply device fixed to an arbitrary position on the surface of the clothing by a cord or the like, and the planar heating element is caused to generate heat. When forming the back fabric body, the laminated body is positioned such that the front surface side is the lining side of the outerwear (clothing side) and the back surface side is the outer material side (outside side) of the outerwear. Then, the heat generated from the planar heating element of the laminated body spreads throughout the laminated body and is not diffused to the outer side, that is, the outside of the clothes, and efficiently warms the entire body of the person wearing the clothes.

The outerwear of the eighth invention is the outerwear of the sixth or seventh invention, and has a side portion connecting the back fabric body and the front fabric body, and the side portion is made of a stretchable fabric. In this outerwear, the stretchable fabric on the side part brings the back fabric body and the front fabric body close to each other, and brings the back fabric body and the front fabric body into close contact with the person wearing the outerwear. Then, the heat from the planar heating element is more effectively transmitted to the wearer to warm the wearer.

To be

(Structure of Fiber Structure Laminate) As schematically shown in FIG. 3, the fiber structure laminate constituting the back fabric body 2 of such a garment 1 comprises a first layer 11 and a first layer 11. 1 layer 1
The second layer 12 is laminated on the front surface of the first layer 1, and the third layer 13 and the fourth layer 14 are laminated on the rear surface of the second layer 12. The first layer 11 is a woven or knitted product obtained by plating or vapor-depositing a metal such as aluminum or silver or carbon on the surface of a fiber woven or knitted product, and the surface side thereof has a plurality of planar heating elements 15 processed into a small plate shape. Are arranged and fixed with an adhesive or the like. The sheet heating element 15 is a heating element having a PTC (positive load resistance) characteristic. It is processed into a substantially rectangular shape and positive and negative electrodes are incorporated in the left and right long side portions, and these electrodes are sequentially connected by a wiring 16. The wiring 16 is finally connected to the power supply device 5 and is supplied with electric power.

In order to connect the electrodes of the individual sheet heating elements 15 to each other, instead of connecting with the wiring 16 as described above, the sheet heating element 15 is arranged between the sheet heating element 15 and the first layer 11. It is also possible to use a printed wiring board made of a heat-resistant film such as polyimide. By further providing a heat transfer layer by metal plating or the like on the back side of this printed wiring board (the side on which the planar heating element is not attached), the diffusion of heat from the planar heating element 15 can be made more effective.

The sheet heating element 15 is preferably set to be self-controlled to have a resistance value of about 30 to 40 Ω in the temperature range of 10 to 40 ° C., and the voltage supplied from the power supply device 5 is about 6 to 12V. By setting to 1.2 ~ 3
The heating value is about W / h. By setting like this,
It is possible to continuously control the temperature of the sheet heating element 15 to a predetermined value, and it is possible to continuously generate heat without excessively increasing the temperature. Further, it is not necessary to artificially adjust the heat generation amount one by one.

As the first layer 11, it is also possible to use a metal fiber obtained by fiberizing a metal such as aluminum or carbon, or a carbon fiber mixed-spun, knitted or knitted in a woven or knitted material. On the other hand, the second layer 12 is composed of a woven or knitted fabric in which two or more woven and knitted fabrics are three-dimensionally connected by a crossover yarn, and for example,
It is composed of "Double Russell", "Double tricot knitting (double structure of single tricot knitted by two-row needle bed tricot knitting machine)" and the like. Such a three-dimensional woven or knitted fabric forms a porosity inside, and the second layer 1
An air layer is formed by itself or between the first layer 11 and the second layer 12.

Like the second layer 12, the third layer 13 is also made of a woven or knitted material such as "double russell", and the second layer 1
An air layer is formed similarly to 2. A plurality of sets of surface fasteners 17a and 17b are attached at intervals on the front surface side of the third layer 13 and the back surface side of the second layer 12, and the first layer 11 is formed by the surface fasteners 17a and 17b. Third layer 1
It is detachably fixed to 3.

Furthermore, a fourth layer is formed on the back surface of the third layer 13.
Layer 14 is laminated and stitched. The fourth layer 14 is for exhibiting heat insulating properties, and is, for example, titanium vapor-deposited polyester fabric or the like. Each of these layers is cut into a predetermined shape, and after the first layer 11 is detachably laminated on the third layer 13 and the fourth layer 14, the first layer 11 is sandwiched so that the second layer 12 and the third layer 13 are sandwiched. The layer 13 and the fourth layer 14 are sewn in a bag shape, leaving a part as an opening, to form a laminated structure.
The openings of the second layer 12, the third layer 13, and the fourth layer 14 can be opened and closed by, for example, fasteners, and the first layer 11 inside can be taken out from the openings as needed.

In the laminated body having such a structure, the surface side (upper side in FIG. 3) of the laminated body is the lining side (wearer side) of the garment 1 and the back side (lower side of FIG. 3) is the front side (side). Wear 1
The back fabric body 2 of the wear 1 is formed as the back surface side) of the wear 1. In the wear 1 configured in this way,
The laminated body forming the back fabric body 2 generates heat and retains the heat, and the back fabric body 2 is efficiently spread over the entire body to effectively warm the wearer's body. In addition, in this wear 1,
Since the stretchable fabric 4 on the side portion makes the back fabric body 2 closely contact with the wearer when wearing, the heat retaining effect is further enhanced.

That is, when the sheet heating element 15 supplied with power from the power supply device 5 generates heat, the second layer 12 having a predetermined three-dimensional structure is the second layer 12 itself or the second layer 12 and the first layer 1.
An air layer is formed between the sheet heating element 1 and the sheet 1, so that heat from the sheet heating element 15 can be retained and spread over the entire back fabric body 2. In addition, the first layer 11 having an excellent heat transfer property also conducts the conduction heat from the planar heating element 15 satisfactorily as a whole, and at the same time, the planar heating element 15
Radiant heat from is reflected to the second layer 12 side. Thus, the entire back fabric body 2 effectively warms the entire back of the wearer.

The back fabric body 2 of the leisure wear 1 is also provided with the third layer 13 and the fourth layer 14, so that the heat generated from the sheet heating element 15 is dispersed outside the leisure wear 1. It is effectively suppressed. [Other Embodiments] (a) Although the laminated body of the above embodiment is provided with the third layer and the fourth layer, it is also possible to form a laminated structure with only the first layer and the second layer.

For example, as the first layer, a synthetic resin such as polyurethane having a heat insulating property impregnated with metal fibers or carbon fibers is prepared, and a necessary outer material is provided on the back surface side if necessary, and the second layer You may use what laminated | stacked. The first layer also transfers heat to the whole and reflects radiant heat, and the polyurethane or the like exerts heat insulating properties to prevent the heat from being dispersed to the outside. (B) In the above-described embodiment, as the first layer 11, a plurality of sheet-like heat generating elements obtained by plating the surface of a fiber woven or knitted material with a metal such as aluminum or silver or carbon and vapor-deposited into a small plate shape. The case where 15 is attached is used as an example. However, as the woven or knitted fabric to which the sheet heating element 15 is attached, a general woven or knitted fabric in which the surface of the fiber woven or knitted fabric is not plated or vapor-deposited with metal, carbon, or impregnated with metal fibers or carbon fibers is used. A synthetic resin having a heat insulating property such as general polyurethane which is not used may be used.

Even in this case, the second layer 12 having a three-dimensional structure forms an air layer in the second layer 12 or between the second layer 12 and the first layer 11, and the air layer is formed from the planar heating element 15. Effectively retains heat throughout the layer. Therefore, the entire jacket is effectively warmed. (C) In the above embodiment, the predetermined fabric is used only for the back fabric body 2, but it is also possible to use this for the front fabric body 3. (D) In the above embodiment, a plurality of sheet heating elements 15 divided into small plates are used. However, if the sheet heating elements are capable of maintaining flexibility, they are divided into sheets in this way. It can be used even if it is not.
