ACOUSTIC ABSORPTIVE FILM MATERIAL
PROBLEM TO BE SOLVED: To provide an acoustic absorptive film material excellent in film material strength and acoustic absorptive effect as a ceiling area constituting film forming material (film ceiling) and a ceiling area constituting member accessory arranged on a ceiling of buildings, further having light weight and incombustibility and suitable for constituting a film ceiling such as an outdoor athletic filed, a gymnasium, an indoor pool, an event hall, a public hall, a ceremonial hall, a station, an airport and a shopping mall.SOLUTION: A fabric contains a resin coating yarn (A) and a resin coating yarn (B) as fabric elements with porosity of 5% or less, a specific gravity of the resin coating yarn (A) is 0.25 or more larger than that of the resin coating yarn (B), occupied volume ratio of yarn (A):(B) to the fabric is 2:1 to 1:2 and especially it has aspects of monolayer fabric, double fabric or triple fabric, especially cross section of the resin coating yarn is flat and especially the resin coating fabric is heat expansive.SELECTED DRAWING: Figure 1
【課題】建築物の天井に設置される天井面積構成膜材（膜天井）、天井面積構成部材付帯物として、膜材強度及び吸音効果に優れ、さらに軽量性と不燃性を具備する、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、空港、ショッピングモールなどの膜天井構築用に好適な吸音性膜材の提供。【解決手段】樹脂コーティング糸条（Ａ）及び樹脂コーティング糸条（Ｂ）を織編要素に含む空隙率５％以下の織物として、樹脂コーティング糸条（Ａ）の比重を樹脂コーティング糸条（Ｂ）の比重よりも０．２５以上大きく、かつ織物に対する糸条（Ａ）：（Ｂ）の占有体積比を２：１〜１：２とし、特に単層織物、または二重織物、または三重織物の態様で、特に樹脂コーティング糸条の断面が扁平で、特に樹脂コーティング糸条を熱膨張性とする。【選択図】図１
