Description

Medical bed with cotton carbon fiber containing latent heat material}

The present invention relates to a medical bed using a cotton carbon fiber containing a latent heat material, and more particularly, to precipitate a decane compound (octadecane, tetrodecane, nonadecan, hexadecane, etc.), which is a latent heat material, on cotton carbon fiber. The present invention relates to a medical bed containing a cotton carbon fiber-based film prepared by spraying and compressing the same, and containing natural fragrances (such as brush and chrysanthemum) in the space inside the bed.

Carbon manufactured to have strong absorption and adsorption properties is called activated carbon and is used for adsorption of poison gas or discoloration of fats and oils. Conventional bedding manufacturing method has been made in the form of attaching the activated carbon fiber to the inside of the fabric constituting the bedding by bonding or absorbing the activated carbon fiber powder in a binder. However, the bonding method has a problem that the odor is continuously induced even after the adhesion, the binder treatment method has a problem that the effect of the activated carbon fiber is weak.

Accordingly, activated carbon-added cotton swab was developed in the Republic of Korea Patent Publication No. 10-2003-0062837. By treating cotton wool with activated carbon, you can achieve a good night's sleep by emitting far-infrared rays.You can adjust the temperature and humidity by placing a futon using activated carbon-treated cotton in the room or closet. To achieve.

The latent heat (heat storage) is the heat absorbed or released at the same temperature when the phase change of the material, in the case of a specific material heat is generated when the phase change from solid to liquid, which is called latent heat, 80cal / g is absorbed when the ice melts The heat of melting of or 540 cal / g of heat which is absorbed when water is evaporated is a typical example.

The latent heat material (phase change material / heat storage material) is used to keep the ambient temperature or the temperature of the applied product constant, or to save energy by absorbing ambient heat to the inside or emitting outside heat by using its latent heat. It is used as a heat storage medium, and such latent heat material is absorbed to the inside of the latent heat material, in order to overcome the problems caused by the flowability of the latent heat material that has been phased into a liquid when the phase change from solid to liquid, or The heat inside the latent heat material is directly contacted with the object in order to be released to the outside.

Among the various latent heat materials, inorganic hydrates causing phase change at a certain temperature are known to satisfy the above conditions, but are not suitable for use of latent heat materials due to physical and chemical instability, and the heat content and melting point increase due to evaporation of crystal water are increased. Due to phase separation and supercooling, the scope of use is limited in practical applications.
