Abstract
【解決手段】粉粒状吸着剤、熱可塑性粉末樹脂及び水流交絡法、及びニードルパンチ法により製造した不織布を構成単位とする吸着性シート。
【選択図】なし
Description
本発明の吸着性シートは、基材層間に吸着剤及び熱可塑性樹脂を含む吸着性シートであって、該基材層の少なくとも片面がニードルパンチ加工及び/又は水流交絡加工が施された不織布であることが好ましい。本願発明者等が知る限り、ニードルパンチ加工、水流交絡加工がなされた不織布は、毛羽が多く、表面平滑性が低いため、フィルター等に用いる吸着性シートには用いられていなかった。しかし、特に基材層間に吸着剤及び熱可塑性樹脂を含むシートに用いれば、シート全体として使用する接着剤を劇的に低減することができるという特異な効果を本願発明者等は見出した。すなわち、従来の基材シートでは、実用に耐える接着強力を得るために接着シートを使用する、あるいは吸着性シート全体への熱プレス負荷を大きくする等の処理がなされており、結果として、高通気抵抗化、脱臭性能の低下等の悪影響を招来していた。一方、本発明のニードルパンチ加工及び/又は水流交絡加工が施された不織布は毛羽が発生するが、かかる毛羽が吸着層に入り込んでアンカーとなり、吸着剤を固定するために用いる吸着層内の接着剤が吸着層と基材層を接着する機能も発揮し、シート全体として使用する接着剤を劇的に低減することが可能となり、柔軟且つ低通気抵抗の吸着性シートを得ることができる。
荷重7gf/cm2の圧力を加えた時の値
(線速30cm/s、供給濃度0.5g/m3の条件下で測定)
粉塵に対する目詰まり度の代用特性。初期通気抵抗から150Pa上昇したときを寿命と判断し、該時点において濾材に堆積した粉塵量を天秤で秤量した値である。サンプルサイズは15cm×15cmで測定実施した。本実施例中では基材シート(粉粒状吸着剤散布側)を上流にして負荷試験を実施。
トルエンガスを用いて線速16cm/sにおいてフィルターの上下流の濃度 をそれぞれガステック製検知管で測定し、上流側のガス濃度から下流側のガス 濃度を減じた値を上流側のガス濃度で除した値の百分率で示した。測定は6c m×6cmに切り取ったサンプルで実施。なお、本特許では上流側濃度は80 ppmとし、測定開始から1分後の除去率のデータを実施例に記載した。
基材シートと粉粒状吸着剤層の平均剥離強度を測定。試験片の大きさは幅50mm、長さ200mmとして、引張速度100mm/minとして実施。
