    • PURPOSE:To impart moisture absorbing/releasing properties by rolling in a columnar manner or laminating in many layers thermoplastic resin composite material formed with a colorant layer on the surface of a base layer containing predetermined wt.% of active clay and thermoplastic resin, integrating them under pressure by heating, and then cutting it in a predetermined planar direction. CONSTITUTION:A material is selected from a group consisting of active zeolite, active kaolinite, active illite, active montomorillonite, activated pearlite, activated berkulite, activated diatomite, activated modified cristobalite, and activated amorphous mineral. A thermoplastic resin composite material formed with a colorant layer on the surface of a base layer made of one or more types of 80 - 30wt.% of active clay and 20 - 70wt.% of thermoplastic resin is wound in a columnar manner, or laminated in a multiple layers, integrated under pressure by heating, and cut in a predetermined planar direction. Since the obtained moisture absorbing/releasing synthetic woodgrain material has remarkably moisture absorbing/releasing properties, the material protective effect of a wooden housing is performed to extend the years of the lifetime.
