ためと考えられる。In the present invention, the above-mentioned sheet-like far-infrared radiator is covered with a synthetic resin non-woven fabric. The synthetic resin as used herein includes polyolefin resins such as polyethylene and polypropylene, polyester resins such as polyethylene terephthalate, cellulose resins, acrylic resins, and fluorine resins. According to the knowledge of the inventor of the present application, the far infrared ray transmittance varies depending on the type of synthetic resin, and among the above synthetic resins, the polyolefin resin is the most preferable material because it has the far infrared ray transmittance. It is considered that this is because far infrared rays penetrate the polyolefin resin itself.

In the range of up to 200 gr / m 2 , it is practical. This range is determined from both the perspective of far infrared ray transmission and the strength of the nonwoven fabric. If the basis weight is 15 gr / m 2 or less, the far infrared ray transmittance is extremely good, but the strength of the nonwoven fabric is low and practical. Disappear. On the other hand, when the basis weight is 200 gr / m 2 or more, the density of the nonwoven fabric is increased more than the required strength, and the far infrared ray transmittance is significantly lowered. The basis weight of the non-woven fabric is 20 gr / m 2 to 100 in terms of economy and practicality.
A range of gr / m 2 is desirable.

However, when an adhesive is used, far infrared rays are partially absorbed by the adhesive and its permeability is lowered, so that the heat fusion of the fibers does not occur. It is preferable to wear it.

As the measurement conditions, the ratio (τx / τ0) of the radiant emittance at a temperature of 30 ° C. and a wavelength of 9,56 μm was determined, and the results are shown in Table 1.

Further, among the non-woven fabrics, when the polyolefin resin is used, it is considered that the polyolefin resin itself has a property of transmitting far infrared rays because the polyolefin resin itself has a good transmittance.
