ARAMID FIBER FAR-INFRARED EMITTING PAPER AND PREPARATION METHOD THEREFOR

Aramid fiber far-infrared emitting paper and a preparation method therefor. Para-aramid chopped fibers and para-aramid pulp fibers are used as paper-based functional materials, which have the excellent characteristics of high specific strength and large specific stiffness. At the same time, the para-aramid chopped fibers and para-aramid pulp fibers may form a paper-like matter having pores and channels, and carbon nanotubes are embedded in the structural pores and channels of the paper-like matter. Therefore, the paper-like matter has good molding quality and composite properties. The far-infrared wavelength emitted by the present aramid fiber far-infrared emitting paper is 4-20μm, the main frequency band is about 10μm, and the far-infrared conversion efficiency reaches as high as 99%. The tensile strength thereof is 0.12-0.18KN/mm2, and the paper may be bent and folded. La présente invention concerne un papier émetteur d'infrarouge lointain en fibre aramide et son procédé de préparation. Les fibres coupées d
