JP2001317889A - Lap robe - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a thin and light lap robe being warmer and having flexibility by adding characteristics of a metal and an oxide having high thermal storage properties to a woven fabric, a knitted fabric, a nonwoven fabric or the like. SOLUTION: The lap robe comprises a metal layer and a base material layer obtained by adhering the metal and the oxide on a base material by a dry plating method. With this constitution, a metal ultra-thin film is closely contacted with fiber and a heat ray dispersed from a body is absorbed by an infrared absorbing function. Accordingly, a high thermal storage effect is incorporated. Thus, even thin fabric can sufficiently raise a heat insulation effect. The metal is adhered by the dry plating method, and hence an adhesion strength is high. Since flexibility of the fiber is not changed, the fiber is easily processed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for sitting in a chair in an office or the like, and covers a waist, a thigh, and a leg, and is used to keep them warm. It is characterized in that metal is adhered.

[0002]

2. Description of the Related Art Conventionally, there has been no hitch provided with a heat retaining function by directly adhering a metal or the like to a substrate such as a woven fabric, a knitted fabric, or a nonwoven fabric by a dry plating method. The air conditioner is too effective, and the office floor gets cold. However, many female employees in office clerks often sit at desks. For this reason, measures have been taken to prevent the cold of the hips and legs by wearing thick socks or leg warmers, or by using a small rectangular rug to make it easier to handle blankets and towels. However, there was no good rug that allowed the metal to adhere to the base material by the dry plating method to store the heat of the body, prevent divergence and prevent the cold. In addition, the conventional ones are relatively thick, bulky and difficult to handle.

[0003]

SUMMARY OF THE INVENTION The present invention provides a warmer, more flexible, thinner and lighter rug by adding the properties of metals and oxides having high heat storage properties to woven fabrics, knitted fabrics and nonwoven fabrics. The purpose is to do.

[0004]

Means for Solving the Problems In order to achieve the above object, the invention according to claim 1 of the present invention comprises a metal layer and a substrate layer in which a metal is adhered to a substrate by a dry plating method. With this configuration, the metal ultra-thin film adheres to the fiber and absorbs heat rays radiated from the body by the infrared absorption function, thereby having a high heat storage effect. For this reason, a thin cloth can sufficiently increase the heat retaining effect without using a thick brushed cloth like a conventionally used blanket, so that a light, thin and easy-to-handle throw is provided. be able to. In addition, by adhering a metal or an oxide by a dry plating method, the adhesive strength is high, and the flexibility of the fiber is not changed.

According to a second aspect of the present invention, the base material is a synthetic fiber such as polyester, nylon, acrylic, polyethylene and polypropylene. Alternatively, it is a blend of the two. With such a configuration, the configuration is suitable for bringing a metal or oxide into close contact by a dry plating method.

In the invention according to claim 3, the metal is a metal having a high heat storage property such as stainless steel, titanium and nickel. Alternatively, it is composed of an alloy of these metals and other metals. Further, it is characterized by being composed of metal oxides, carbides and nitrides. With this configuration, it is excellent in infrared absorption function, absorbs heat radiated from the body, and exhibits a high heat storage effect, so that it is warm. Stainless steel does not corrode easily and is economical. In addition, alloys of titanium and silver are less likely to cause metal allergy, and at the same time, can impart antibacterial properties, so that there is a characteristic that it is difficult for bacteria to propagate,
More preferred. When synthetic fibers and natural fibers are blended, the ratio of the natural fibers is preferably up to 5% by weight.

Embodiments of the present invention will be described below. FIG. 1 shows a substrate 2 composed of a woven fabric, a knitted fabric, a nonwoven fabric, or the like.
The metal 1 is brought into close contact with one side by dry plating. FIG. 2 is a view showing a state in which the body is mounted after finishing to a shape suitable for a rug. Use it so that the dry-plated surface contacts the body side, that is, the legs and waist. Either surface may be used, but by using it in this way, the body temperature is immediately transmitted to the metal surface, where it is stored and warmer.

[0008] Dry plating includes processing methods such as vacuum vapor deposition, sputtering, ion beam, and ion plating. When taking a look at the sputtering method as an example, when processing a base material, a basic method is used. After the material is dried, it is spread in a sealable casing, and a bar-shaped anode and a metal target for sputtering are set in front of the casing. After reducing the pressure in the casing to about 1 × 10 ⁻³ Torr, argon gas was introduced to adjust the pressure in the casing to a low-pressure argon gas atmosphere of about 5 × 10 ⁻⁴ Torr. 400 between the cathode
When a DC current of 〜800 V and 2１００100 A is passed, the metal jumps out of the cathode target and adheres to the surface of the substrate.

According to the present invention, a metal or an oxide is firmly adhered to a cloth-like base material such as a nonwoven fabric, a woven fabric, or a knitted fabric by a dry plating method. A warm throw can be provided. Even if a metal is adhered to a substrate such as a nonwoven fabric or a woven fabric by a dry plating method, the original softness, air permeability, and feel of the substrate do not change. It is also easy to freely cut into any size.
