SOUND ABSORBING SHEET
PROBLEM TO BE SOLVED: To provide a lightweight and flexible noncombustible interior material that excels in reverberation suppressing and sound attenuating effects and is suitable for membrane ceiling structure used in indoor sports competition facilities, gymnasiums, indoor swimming pools, performance event halls, public auditoriums, ceremonial event facilities, railway station lobbies, airport lobbies, open-ceiling shopping malls and so forth.SOLUTION: A sound absorbing sheet has as a ventilation and diffusion layer fabric cloth made by weaving a multi-filament yarn, and configured as a laminate made by covering at least one face of this fabric cloth with a thermoplastic resin layer. Many ventilation holes of 0.5 to 2.5 mm in bore are so formed all over this laminate that a hole area rate of 2.5 to 12.5% is achieved as the total area of these ventilation holes, and the thermoplastic resin layer contains 1.5 to 10 mass% of heat-expanded particles relative to the thermoplastic resin layer.SELECTED DRAWING: Figure 1
【課題】軽量性とフレキシブル性とを有し、反響抑止効果と音響減衰効果とに優れ、屋内競技場、体育館、屋内プール、イベントホール、公会堂、冠婚葬祭式場、駅舎ロビー、空港ロビー、ショッピングモール吹き抜けなどの膜天井構築用に好適な不燃内装材の提供。【解決手段】マルチフィラメントヤーンを製織してなる繊維布帛を通気拡散層として含み、この繊維布帛の少なくとも片面に熱可塑性樹脂層を被覆形成してなる積層体として、この積層体の全面に孔径０．５〜２．５φｍｍの通気孔を多数形成し、この通気孔の面積総和としての開孔率２．５〜１２．５％を有し、さらに熱可塑性樹脂層が熱膨張性粒子を熱可塑性樹脂層に対して１．５〜１０質量％含むようにする。【選択図】図１
