PROBLEM TO BE SOLVED: To provide a manufacturing method of a hood insulator using a resonance structure unwoven fabric, capable of mass production and continuous production.SOLUTION: The hood insulator is configured such that a skin material 2 includes a micro-resonance layer 23 having many openings formed therein, a sound wave reduction phenomenon is generated by a resonance effect to effectively reduce the noise of an engine room, there is no need to increase weight and a thickness in order to improve sound absorption performance, and a resonance structure unwoven fabric advantageously is used for weight saving and maximization of space utilization. The micro-resonance layer is formed by a printing method, thereby achieving uniform print basis weight and thickness, and enabling mass production and continuous production.SELECTED DRAWING: Figure 1
【課題】大量生産及び連続生産ができる共鳴構造不織布を用いたフードインシュレーターの製造方法を提供する。【解決手段】表皮材２が、多数の開口が形成された微細共鳴層２３を含み、共鳴効果による音波減殺現象を発生させて、エンジンルームの騒音を効果的に低減し、吸音性能向上のために重量及び厚さを増加する必要がなく、軽量化及び空間活用性の極大化に有利な共鳴構造不織布を用いたフードインシュレーターを提供し、前記微細共鳴層を印刷法で形成することで、均一な印刷坪量及び厚さを有するようにし、大量生産及び連続生産ができる。【選択図】図１
