PROBLEM TO BE SOLVED: To continuously manufacture a functional sheet where a functional agent is dispersed and deposited in the thickness direction of nonwoven fabric.SOLUTION: A manufacturing method of a surface sheet 10 is provided for manufacturing the surface sheet 10 by depositing a skin care agent 15 on a three-dimensional sheet 10b. An ultrasonic generator 2 for converting the skin care agent 15 into fine particles by supersonic oscillation and a suction device 3 for orienting the dispersion direction of the skin care agent 15 converted into fine particles are used. The mist of the skin care agent 15 is generated, the skin care agent 15 that is converted into the fine particles by oscillating the ultrasonic wave using the ultrasonic generator 2. The skin care agent 15 converted into the fine particles in a mist shape is scattered in the air. The skin care agent 15 converted into the fine particles and scattered in the air is passed by using the suction device 3 in the thickness direction of the conveyed three-dimensional sheet 10b. The skin care agent 15 converted into the fine particles is dispersed in the thickness direction of the three-dimensional sheet 10b and is deposited in the inside.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】機能剤を不織布の厚さ方向に分散して付着させた機能性シートを連続的に製造すること。【解決手段】立体シート10bにスキンケア剤15を付着させて表面シート10を製造する表面シート10の製造方法である。超音波の発振によりスキンケア剤15を微粒子化する超音波発生装置2と、微粒子化したスキンケア剤15の分散方向を方向付ける吸引装置3とを用い、超音波発生装置2を用いてスキンケア剤15に超音波を発振して微粒子化したスキンケア剤15の霧を発生させて、空気中に霧状に微粒子化したスキンケア剤15を飛散させ、空気中に飛散させた微粒子化したスキンケア剤15を搬送される立体シート10bの厚み方向に吸引装置3を用いて通し、微粒子化したスキンケア剤15を立体シート10bの厚み方向に分散させてその内部に付着させる。【選択図】図1
