Functional bed mattress containing germanium {FUNCTIONAL BED MATTRESS COMPRISING GERMANIUM}

The present invention relates to a functional bed mattress containing germanium, and more particularly, by manufacturing a bed mattress by mixing germanium and various additives, electromagnetic waves are blocked, and a large amount of far-infrared rays and negative ions beneficial to the human body are emitted to circulate blood. and metabolism, it is harmless to the human body and has excellent antibacterial and deodorizing power to prevent infection with various germs, fine dust, and viruses in advance, as well as to prevent the growth of mold or microorganisms that can be generated in mattresses. It is about a functional bed mattress containing germanium that can suppress and keep the polluted air in the bedroom clear and clean.

In general, bed mattresses include spring mattresses based on springs and sponge mattresses using synthetic resin sponges.

The spring mattress is the most commonly used one, and although it is cozy due to the cushion of the spring, it causes back pain because the center of gravity is concentrated on the head and buttocks when sleeping, and the function is deteriorated due to wear and rust of the spring. The disadvantage is that the mattress must be replaced after a certain period of use. In addition, there are problems with functional defects such as insufficient heating function, noise, dust pollution, and bacterial propagation.

Although the sponge mattress is cheap, it does not have enough elasticity to support the body for a long time, so the part where the weight is concentrated is depressed, and since it is a chemical material, it can cause allergic diseases or skin troubles on sensitive skin, and has a thermal function There are problems with functional defects such as insufficiency, dust pollution, and bacterial propagation.

On the other hand, there is an urgent need for a mattress that can fully relieve fatigue and have a useful effect on the human body while resting for modern people who are exposed to many harmful substances and stresses such as indoor and outdoor environments and electromagnetic waves, which have recently become more serious.

To reflect these consumer needs, mattresses capable of performing antibacterial and deodorizing functions have been disclosed. For example, domestic utility model registration No. 380174 'antibacterial mattress cover impregnated with nanosilver particles' and There are mattress technologies with antibacterial function added, such as domestic utility model registration No. 285972 'mattress with antibacterial agent'.

However, adding an antibacterial function to such a mattress has a problem that the antibacterial effect is inhibited when used for a long time, and indoor air is polluted by not only odors unique to the house, but also odors of food and odors unique to various pets present in the room. However, there is a problem in that the smell as described above is absorbed into the mattress as it is and causes sleep disturbance.

Therefore, it is harmless to the human body and has excellent antibacterial and deodorizing power to prevent infection with various germs, fine dust, and viruses in advance, as well as suppressing the growth of mold and microorganisms that can be generated in the mattress and contaminating the bedroom There is an urgent need for a new and advanced mattress that can keep the air clean and clean.

In the above step, the wool yarn coated with PVA is passed through the first feed roller, heat-treated in a heater at a temperature of 170 to 180 ° C, and then a second feed It can extend|stretch while passing a roller.

Subsequently, weaving may be performed using the stretched wool yarn.

In the above step, weaving may be performed by interlacing the stretched wool yarn in a cross shape in the transverse and longitudinal directions. For example, the weaving of the wool yarn is arranged at equal intervals so that the stretched wool yarn is adjacent to each other, or the stretching It can be done by twisting and weaving the wool yarn.

The configuration of weaving using the stretched wool yarn in the above step is a known technique in the art, and thus, a detailed description thereof will be omitted for convenience of description and clarity of the technical idea of the present invention.

Next, the woven wool yarn may be washed with hot water to produce a microfine paper fabric.

In the above step, the woven wool yarn can be washed with water to remove the PVA coating layer coated on the surface of the wool yarn to prepare a microfine fabric. While washing with hot water, ultra-fine paper fabrics can be produced.

Hereinafter, with reference to the accompanying drawings, a preferred embodiment of a functional bed mattress containing germanium according to the present invention will be described in more detail.
