Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to heated garments. More specifically, the present invention relates to a heated garment in which a heating element is combined inside.

BACKGROUND ART Conventionally, clothing made of quilted materials and the like that incorporate heating elements to actively warm the body have been sold. With these clothes, only the part where the heating element was attached was abnormally hot, sometimes causing burns. Furthermore, areas without a heating element do not feel as warm, indicating that the body is being actively warmed, and because there is a large temperature difference between different parts of the body, it is easier to feel the cold. No effect seen.

Problems to be Solved by the Invention Under the current situation, there is no clothing that has the function of actively heating and keeping the entire human body warm. The present inventors have investigated the heat transfer mechanism for keeping the human body warm in clothing, using thermal mannequins, thermal resistance measuring devices, thermal photography,
Through intensive research using devices such as infrared thermometers, we have demonstrated the ability to keep the human body warm by supplying the heat emitted from the heating element to the entire inside of clothing, making it possible to keep other clothing warm even in cold weather. The purpose is to provide heated clothing with great heat retention that allows you to stay warm even when you put it on.

Means for Solving the Problems The present invention is characterized in that a heating element is combined inside a garment, and that at least one side of the fabric forming a space inside the garment in which the heating element is located has an uneven portion. In heated clothing.

Hereinafter, the specific structure of the heated garment of the present invention will be explained.

The term "heated clothing" as used in the present invention refers to clothing made by combining a heating element with a garment made with a layered outer layer, a lining, or a combination of down or batting.

The shape of the garment is not particularly limited, such as the jacket/noseau shown in Figure 1, piste, blouson, coat, vest, skirt, hoodie, etc., but at least one fabric facing the space inside the garment where the heating element is located is ridged. Alternatively, it is necessary that the garment be characterized by having irregularities such as dots.

In addition, the method of combining the heating element is as shown in Fig. 2.
A device capable of supporting a heating element such as the like is provided, and the heating element 4 is mounted therein. The location of the pockets and pockets is arbitrary, but effective locations where warm air heated by the heating element can easily be supplied to the entire inside of the garment through the recesses in the fabric facing the inner space of the garment are: The waist, abdomen, hem of a jacket, and hem of a jacket or skirt are preferred.

As shown in FIG. 3, the space inside the garment as used in the present invention refers to the space formed by the skin surface 12 or the underwear 13 such as a shirt or sweater and the outer material 1 in the case of a garment made with a heavy outer material.
10 and 11 For items made with lining or a combination of down or filling, the outer material 1 and the lining 2, or the space or skin surface formed by the outer material and the lining, down or filling, or the underwear such as a shirt or sweater and the lining. Space 1o, ii formed by
It is. Of these spaces, the space 11 where the heating element is located, excluding the pocket protrusion, is the space within the garment where the heating element is located as referred to in the present invention.

The heating element referred to in the present invention includes an electric heater body warmer, a disposable body warmer, a benzene body warmer, and the like. An electric heater body warmer is a body warmer that generates heat by energizing a linear heating element using nichrome wire or a planar heating element using carbon, etc., from a battery, accumulator, or direct power supply. Disposable body warmers refer to body warmers sold on the general market that utilize the exothermic oxidation reaction of iron powder. The size and thickness of the heating element are not particularly limited, but in order to maintain the form and aesthetics of clothing without inhibiting the motor functions of the human body,
Preferably, the heating element has a length of 1 (1 to 100 m, a width of 100 to 300 wm, and a thickness of 1 to 1 G+++m). Also, a heating element whose temperature does not exceed 60°C is a preferable heating element since there is no fear of burns.

The fabric constituting the heated garment in the present invention includes synthetic fibers such as polyamide fibers, ester fibers, and polyacrylic fibers, semi-synthetic fibers such as acetate, rayon,
Knitting and woven fabrics using yarns made from recycled fibers such as cupro, and natural fibers such as cotton, linen, and kuru, either alone or in combination;
It is non-woven.

Furthermore, the term "fabric" also includes films made of polyvinyl chloride, polyester, f'9 ethylene, etc.

Furthermore, these fabrics may be made by laminating polyurethane-based or polyacrylic ester-based polymers on one or both sides, but when such fabrics are used to make clothing, the space inside the clothing where the heating element is located At least one of the fabrics facing the garment must have a ridge-like or dot-like unevenness 15, and the height of the protrusion should be one or more.

In the present invention, methods for manufacturing the uneven portions of the fabric include cordless knitting, nailless rib knitting, nailless rib knitting, enze processing, etc., and the ribbed uneven portions can be produced by these methods. In addition, gravure coating on fabric using resins such as polyester, polyamide, and polyvinyl chloride, as well as films using polymers such as polyethylene, I-soliester, and polyvinyl chloride, can be used to create dots. It is possible to produce unevenness. The fabric may be designed to have an uneven portion on at least one side.

This ridged shape refers to one in which concave portions and convex portions alternately continue substantially linearly over the entire surface of the fabric, as shown in FIGS. 4(a) and 4(2), for example. As shown in Figure 4 (/'1), the convex part is circular.
Points are squares, ellipses, etc. that are continuous in a broken line and are formed in stripes, base stripes, radials, etc.

In addition, when the fabric is used as clothing, the direction of the convex portions is arbitrary, but in the case of ridges, the direction in which the ridges can maximize the function as a heating garment is at the center of the back, center of the front, or along the line. A sewing specification in which the heating element is located parallel to a mountain line is preferable, and a sewing specification in which the heating element is located at the center of the ball is preferable only in the case of a radial pattern.

The cross-sectional shape of the uneven portion is shown in FIG. The height 16 of the convex portion in the present invention is the distance from the top of the convex portion to the deepest portion of the concave portion, the width 17 of the convex portion is the distance from one end of the convex portion to the other end, and the width 18 of the concave portion is the distance from the top of the convex portion to the deepest portion of the concave portion. is the distance from one end to the other.

The width of the convex portion is preferably 1 to 20 mm, more preferably 1 to 10 mm considering the texture of the fabric. In addition, the width of the recess is preferably 1 to 20 m for ridge-shaped recesses and 3 to 20 m for single-point recesses; The width of the dotted recesses is preferably 3 to 15 m.

Furthermore, when the fabric is placed on a flat surface, the contact area of the convex parts is preferably 20 to 90%, and the height of the convex parts is preferably 1 to 15 m, but more preferably the contact area is 40 to 80%, and the height of the convex parts is 1 to 15 m. 1.5
~10m. The length of the convex portion is arbitrary, but it must be ridge-like or dot-like. If the contact area of the convex portion is less than 20%, the concave portion will bend and cover the area around the heating element, causing localized heating and the garment will not function as a heating garment. If it is larger than 9G91, the heat of the heating element will remain locally and the entire inside of the garment cannot be heated, and it will not function as a heating garment.

EXAMPLE Next, an example will be shown. Table 1 shows the heat retention properties of the clothes in this example, which were measured using the following method. Furthermore, it is generally accepted that humans can sense the difference in temperature between clothes they wear by as little as 0.01 clo.
