SOUND ABSORPTION/INSULATION MATERIAL AND ITS MANUFACTURING METHOD
To further properly improve the performance of a sound absorption/insulation member which is formed of a cellulosic fiber.SOLUTION: A manufacturing method of a sound absorption/insulation material includes a first process for laminating cellulosic fibers on a net material 62 while sucking a liquid of an undiluted solution through the net material 62 from a liquid suction part 63 with a molding mold 60 set in a state of being immersed in the liquid undiluted solution containing the cellulosic fibers, and a second process for forming a protrusion 15 by drying the cellulosic fibers which are laminated on the net material 62, and forming a contour of a communication part 30 by drying the cellulosic fibers which are laminated on a recessed region 70. The inside and outside of the protrusion 15 are made to communicate with each other by a communication path 32 of the communication part 30 formed of an arrangement trace of a salient part 72 by removing the dried protrusion 15 and the communication part 30 from the molding mold 60.SELECTED DRAWING: Figure 10
【課題】セルロース系繊維で形成された吸遮音部材の性能をより適切に向上させることにある。【解決手段】成形型６０を、セルロース系繊維を含む液状の原液に浸した状態として、液体吸入部６３から網材６２を通して原液の液体を吸入しつつ、網材６２の上にセルロース系繊維を積層させる第一工程と、網材６２の上に積層したセルロース系繊維を乾燥させて凸部１５を形成し、凹部位７０に積層したセルロース系繊維を乾燥させて連通部３０の外形を形成する第二工程と、乾燥状態の凸部１５と連通部３０を成形型６０から取外すことにより、突起部７２の配置跡で形成された連通部３０の通路部３２によって凸部１５の内外を連通する。【選択図】図１０
