Description
ρ=(W/1002)×(10/T)・・・(1)
ρ:密度(g/cm3)
W:JIS L 1913に準じて測定した単位面積当たりの質量(目付)(g/m2)
T:0.1kPaの荷重下での不織布の厚さ(mm)
燃焼性試験および通気量測定に使用した基材、表皮材、および難燃化材の仕様は以下の通りである。各実施例および比較例の吸音材には、下記仕様の基材および表皮材のみを積層したもの、およびその間に難燃化材を重ねたものを用いた。尚、本実施例および比較例で用いた難燃化材は熱融着性シートとしての機能も備えており、各実施例および比較例のうち、難燃化材を有する吸音材の基材および表皮材は難燃化材により接着されている。一方、難燃化材を有さない吸音材の基材および表皮材は、ニードルパンチにより一体化されている。
〔基材〕
繊維材料:ポリエステル繊維と低融点ポリエステル繊維との混合繊維
繊維径:φ14μm
目付:300g/m2または500g/m2
厚み:10mm
製法:ニードルパンチ
〔表皮材〕
繊維材料:オレフィン繊維
繊維径:φ9μm
目付:50g/m2
厚み:1mm
製法:スパンボンド
〔難燃化材〕
繊維材料:ポリエステル繊維、ポリオレフィン繊維、またはポリアミド繊維
目付:30g/m2
厚み:0.1〜1mm
実施例1:表皮材/難燃化材(ポリエステル繊維;0.2mm)/基材(300g/m2)
実施例2:表皮材/難燃化材(ポリオレフィン繊維;0.2mm)/基材(300g/m2)
実施例3:表皮材/難燃化材(ポリアミド繊維;0.2mm)/基材(300g/m2)
実施例4:表皮材/難燃化材(ポリエステル繊維;0.2mm)/基材(500g/m2)
実施例5:表皮材/難燃化材(ポリエステル繊維;0.5mm)/基材(300g/m2)
比較例1:表皮材/基材(300g/m2)
比較例2:表皮材/基材(500g/m2)
比較例3:表皮材/基材(300g/m2)/表皮材/基材(300g/m2)
比較例4:表皮材/難燃化材(ポリエステル繊維;1mm)/基材(300g/m2)
比較例5:表皮材/難燃化材(ポリエステル繊維;0.1mm)/基材(300g/m2)
B=(s/t)×60・・・(2)
B:燃焼速度(mm/min)
s:燃焼距離(mm)
t:燃焼時間(秒)
吸音材の通気量に応じた吸音性能を評価するため、以下の試験体を用いて残響室法吸音率の測定を行った。表2と図4にその測定結果を示す。
〔試験体〕
積層構造:表皮材/難燃化材/基材/表皮材/難燃化材/基材
通気量:5、27、50、2、および58cm3/cm2・s
S:試料の面積(m2)
A:等価吸音面積(m2)であり、下記の(4)式により求めた。
A=55.3V/c・[1/Τ2−1/Τ1]・・・(4)
V:試料を入れない状態における残響室の容積(m3)
c:空気中の音速(m/s)
Τ1:試料を入れない状態における残響室の残響時間(s)
Τ2:試料を入れた状態における残響室の残響時間(s)
表2および図5の吸音性能試験の結果から、吸音材は通気量が5〜50cm3/cm2・sのときに(試験体1〜3)、低周波から高周波までの広い音域にわたって高い吸音性能を示すことが確認された。また、通気量が5cm3/cm2・s未満になると(試験体4)、高周波域における吸音性能が低下し、通気量が50cm3/cm2・sを超えると(試験体5)、低周波域の吸音性能が低下することが確認された。これらの結果から、吸音材の吸音性能を最適化するためには、通気量5〜50cm3/cm2・sを目安として調整することがより望ましいと考えられる。
