材の難燃性も向上した。As described above in detail, in the cushioning material according to the present invention, since the foam is impregnated with the dispersion liquid in which the charcoal powder is dispersed, and the charcoal powder is filled in the foam, air is generated. When flowing through the inside of the foam, the moisture such as sweat contained in the air, ammonia,
Gases that cause odors such as formaldehyde, trimethylamine, and methyl mercaptan are adsorbed by the charcoal powder filled in the foam, and the cushioning material is improved in moisture absorption, deodorization, mold resistance, and mite. In addition, due to the far-infrared radiation performance of the charcoal powder, the heat retention of the charcoal powder when used in a futon or the like was improved, and the charcoal powder also improved the flame retardancy of the cushion material.

ようになり、上記のような特性がさらに向上した。Also, when the foam is impregnated with a dispersion of the charcoal powder as in the cushioning material of the present invention and the charcoal powder is filled into the foam, the charcoal powder is mixed with the raw material of the foam. As compared with the case where foaming is performed by foaming, a larger amount of charcoal powder can be filled in the cushion material, and the above-described characteristics are further improved.

ようになった。Also, as in the method of manufacturing a cushioning material according to the present invention, a foam is impregnated with a dispersion obtained by dispersing charcoal powder in a resin solution, and then dried, and the foam is filled with charcoal powder. When the charcoal powder is used, the charcoal powder is filled in a state of being sufficiently adhered to the surface of the foam and the bubbles inside the foam, so that the charcoal powder is prevented from detaching from the foam, and the charcoal powder is removed. The characteristics of the cushioning material in which the foam is filled are now stably maintained over a long period of time.

ようになった。When an adhesive containing charcoal powder is used for bonding the cushioning material as described above in the present invention, an odor caused by various solvents contained in the adhesive is mixed into the adhesive. It is absorbed by the charcoal powder, and the generation of offensive odor is suppressed, and the adhesive is given flame retardancy,
The generation of toxic gas due to the burning of the adhesive itself has also been suppressed.
