Luconia ceramics, magnesia ceramics, with a particle size of 0.5 to 5. Powder-like materials with a diameter of 0 μm are preferable. Containing far-infrared emitting ceramics in non-woven fabric As a method of tightening, for example, fiber-forming resin contains far-infrared emitting ceramics. There is a method of using fibers spun with fibers as constituent fibers of non-woven fabrics, and a method of using far-infrared rays in non-woven fabrics. Methods such as impregnation with a binder in which radiation-emitting ceramics are dispersed are used. . In this way, when far-infrared emitting ceramics are contained in a nonwoven fabric, When the pad is attached to the toe, the far-infrared effect of far-infrared emitting ceramics As a result, thermal molecular movement occurs in the human body, causing the human body to self-heat and hyperemia to occur in a short period of time. It promotes blood flow and can have medical and health-promoting effects.

[0011] In addition to far-infrared emitting ceramics, zeolite is replaced with metal ions. Antibacterial zeolite, polyvinyl, polyacrylate, polyester, polyester Antioxidants with piganides or quaternary ammonium salts immobilized on polymer chains such as Bacterial agents, deodorants such as activated carbon and zeolite can be contained in nonwoven fabrics. Each of these ingredients can be used singly or in combination, taking into consideration the purpose and conditions of use. In addition to the breathability, water absorption, and cushioning properties inherent to nonwoven fabrics, It is possible to add functions such as heat retention, antibacterial properties, and deodorization properties.

0012 In addition, when manufacturing the toe protection pad of the present invention, two A method of overlapping sheets of nonwoven fabric and sealing the area around these nonwoven fabrics, leaving an opening. In addition, as shown in Figure 3, continuous sheet-like nonwoven fabrics are stacked one on top of the other, and this We adopted a method of sealing and cutting the paper into a circular shape, and then cutting it in half along the center line. You can also Also, one piece of non-woven fabric can be folded and stacked to make two pieces of non-woven fabric. good.
