FLOOR IMPACT NOISE REDUCTION CARPET
To provide a carpet capable of reducing floor impact noise.SOLUTION: A floor impact noise reduction carpet is configured so that, on a rear surface of a surface pile layer, a non-gel foam layer and a lining layer are laminated in this order, the non-gel foam layer includes a natural rubber latex and styrene-butadiene rubber (SBR), an expansion ratio of the non-gel foam layer is 5 times to 7 times, a basis weight of the lining layer is 30-150 g/m, and ΔLL(I) rank of the carpet measured in accordance with a measurement method of a floor impact noise level in a site of an architectural structure in JIS A 1418 (1995) is 4 or more.SELECTED DRAWING: Figure 1
【課題】床衝撃音を低減できるカーペットの提供。【解決手段】表面パイル層の裏面に、ノンゲルフォーム層と、裏打ち層とが順に積層され、前記ノンゲルフォーム層が、天然ゴムラテックスとスチレンブタジエンラバー（ＳＢＲ）を含んでなり、前記ノンゲルフォーム層の発泡倍率が、５倍〜７倍であり、前記裏打ち層の目付が３０〜１５０ｇ／ｍ２であり、ＪＩＳ Ａ １４１８（１９９５）の建築物の現場における床衝撃音レベルの測定方法に準拠して測定したカーペットのΔＬＬ（Ｉ）等級が４以上である床衝撃音低減カーペット。【選択図】図１
