In the present invention, the inorganic porous material, which is charcoal and / or mineral, is used in the range of 1% by weight to 13% by weight, and when it is mixed in an amount of 1% by weight or less, antibacterial and deodorizing effects cannot be expected, and 13% by weight or more. In the case of mixing, it is difficult to mix with other materials, so that the strength of the memory foam is lowered, thereby making it difficult to mold.

In addition, the memory foam of the present invention contains 1 to 13% by weight of at least one inorganic antibacterial powder selected from the group consisting of silver, calcium phosphate and zeolite as a separate antibacterial component.

In particular, the silver used in the present invention is known to be particularly useful for shielding the antimicrobial effect and electromagnetic waves, and the addition of silver powder of several nanometers in size. When 1 wt% or less of silver loses the characteristics of the function of the electromagnetic shielding, and when 13 wt% or more is added, the electromagnetic shielding function is excellent, but the physical properties of the mixture are deteriorated. In the case of zeolite and calcium phosphate, it is not preferable because it is added as a powder having a size of several nanometers, and if it is out of the range of 1 to 13% by weight, it will cause a decrease in antibacterial effect or a decrease in physical properties of the composition.

Other additives that may be incorporated into the memory foam of the present invention may include certain directional means for masking the urethane odor of the foam. Such fragrance means is preferably a fragrance material in which the liquid natural fragrance stock solution is put into a microcapsule made of a known polymer material to control the amount of release of fragrance. Examples of the natural flavors include lavender flavors, brush flavors, and the like.

The amount of these added is 0.5 to 1.5% by weight relative to the total weight. Typically, the fragrance duration is short when adding the fragrance liquor, while the microencapsulation as in the above configuration can sustain the release of the fragrance.

In the memory foam of the present invention, an inorganic porous material and an inorganic antimicrobial powder are mixed and stirred in a polymerized polyurethane resin melt to prepare a final product through a process of press molding. The molding process may use methods and apparatus known in the art, and are not particularly limited in the present invention.

In the case of the antimicrobial test on the sanitary fabric of the composition of the present invention, it was shown to have a reduction rate of 99.9% or more against Staphylococcus aureus. In addition, by the porous of the charcoal and / or mineral showed more than 97% (after 30 minutes), the odor is removed.

In addition, the memory foam of the present invention has a function of absorbing ambient heat such as body temperature to radiate far infrared rays to the outside.

In general, infrared rays indicate electromagnetic waves corresponding to a wavelength range of 0.76-1000 µm, and far infrared rays in the wavelength range of 4-16 µm, in particular, are known to give the most pleasant feeling to humans and have a good thermal effect. When far-infrared energy having a wavelength similar to that of the water molecule is radiated to the human body, the far-infrared energy is resonantly absorbed by the water molecule to increase the vibration of the water, thus bringing about a warming effect and a very fine massage effect. As a result, far-infrared rays can bring about beneficial effects on the human body such as temperature increase of subcutaneous layer, microvascular expansion, blood circulation promotion, metabolism strengthening, blood flow disorder relieving. The memory foam of the present invention showed an emissivity of 89% or more at 37 C and 5-20 μm as a result of far-infrared emissivity, while the unprocessed product showed 23 C in thermal imaging, whereas the memory foam of the present invention was 24.9. With C, it was confirmed that the temperature increase effect appeared about 2 C.

In addition, it was confirmed that the anion release test for the memory foam of the present invention appeared as 340 ion / cm 3, the effect of stabilizing blood pressure and comfortable breathing can be expected through the released anion.
