Abstract
Description
実施例1の繊維状フィラーは、垂直にラップ仕上げされた不織布プロセスを通して製造された極めて嵩高な不織布ウェブであった。使用したステープル繊維は、バインダー成分として使用される複合繊維を用いた再生ポリエステル(PET)繊維であった。
実施例2~5の繊維状フィラーは、従来のエアレイイングウェブ形成機(Rando Machine Corporation,Macedon,New Yorkから商標名「RANDO-WEBBER」で入手可能)を使用することによって製造した極めて嵩高な不織布ウェブであった。異なるステープルファイバーを使用した場合、ステープル繊維を重量パーセントでブレンドした。不織布ウェブの厚さは15~30.0mmの範囲であり、ウェブの面積重量(坪量)は、1平方メートル(gsm)あたり100~400グラムの範囲であった。次いで、不織布ウェブを100~250℃の範囲の温度を有するスルーエアーオーブンに通し、事前接合されている嵩高な不織布ウェブを得た。
表2は、比較例A及びBで使用した材料を列挙する。比較例A及びBは市販品であり、繊維状フィラー材を含まない。
シーファー擦傷試験
シーファー擦傷試験を行って、SCOTCH-BRITE(商標)Dobie擦り磨きパッドからポリプロピレンメッシュで被覆した実施例1の繊維状フィラー材並びに比較例A及びBの製品の相対研磨性(relative abrasiveness)を評価した。試験は、米国特許第5,626,512号(Palaikisら)に記載されているものと概ね同様の方法で実施した。繊維状フィラー材を円形パッド(直径8.25cm)にカットした。試験は、2.25kgの荷重下で約250rpmで5000回転する円形繊維状フィラーパッドを用いて、円形アクリル系ワークピース(直径10.16cm)の表面に水を毎分40~60滴の速度で適用して実施した。結果は、視覚的評価として、又は1~5の、アクリルディスク上に残っている擦傷パターンの3つのサンプルの視覚的評価の平均として与えられる。シーファー擦傷視覚的評価を表3に記載する。
物品清掃効果試験は、米国特許第5,626,512号(Palaikisら)に記載されているのと概ね同様の方法で実施した。直径8.25cmの18ゲージステンレス鋼パネルを、120グラムのミルク、60グラムのチェダーチーズ、120グラムのハンバーガー、120グラムのトマトジュース、120グラムのチェリージュース、20グラムの小麦粉、及び100のグラニュー糖、並びに1つの卵からなる食品汚れ混合物でコーティングした。コーティングされたパネルを230℃のオーブン中で14分間焼成し、最終コーティング重量は0.5グラム未満であった。
実施例1は、SCOTCH-BRITE(商標)Dobie擦り磨きパッドからポリプロピレンメッシュで被覆し、比較例A及びBをきれいにすすいだ。次いで、試料を、約500mlの4%食器用洗剤水溶液を含有するトレーに完全に浸漬させた、試料を、泡立ちが視覚的に見えるまで、手で5回未満の手で絞った。視覚的評価を表6に記載する。
実施例1~5並びに比較例A及びBの吸水率は、これらの水の可能な最大量について測定した。吸水性を試験するために、実施例1~5の繊維状フィラー並びに比較例A及びBの発泡体フィラーのみを試験した。試料は、水をそれらに通して流すことにより清掃し、試料が泡立ちを停止するまでそれらを絞った。試料を200°Fのオーブンに入れて乾燥させ、重量が変化しなくなるまで乾燥させた。乾燥重量を、「A」で記録した。次いで、試料を温かい水道水、約46℃に浸漬し、絞って封入された空気を除去した後、水を約1分間吸収させた。次いで、試料を取り出し、1分間空気乾燥させて過剰な水を除去した。各試料の初期重量を「A」として記録し、20秒後の湿潤重量を「B」として記録した。フィラー吸水率、「C」は、その元の乾燥重量から保持される水の総量として定義され、以下の式を使用して計算される。
フィラー吸水率C=(B-A)/A
実施例1~5の繊維状フィラー並びに比較例A及びBの発泡体フィラーの長さ(l)、幅(w)、及び厚さ(t)は、デジタルキャリパー(500-196-30、Mitutoyo)を使用してミリメートル単位で測定した。各試料の長さ、幅、及び厚さを乗じることによって各試料の体積(m3)を計算し、次いで記録した。材料乾燥重量(g)を、デジタル秤(Mettler Toledo製のPM400)を使用して測定し、0.001グラムの位まで記録した。試料の密度は、以下の式を用いて計算した。
密度=乾燥重量(g)/体積(m3)
圧縮に対する抵抗は、物品を10ミリメートルの設定点まで圧縮するためのニュートンでの力として定義される。ChatillonからのLF Plus引張フレームを使用して試験を実施した。上部プレートの寸法は、5.5インチ×4インチであった。引張試験機に、5,000Nのロードセルを設置した。圧縮速度を、100mm/分に設定した。実施例1~5の繊維状不織布フィラー並びに比較例A及びBの発泡体フィラーを、引張試験機のホルダに配置した。引張試験機によって報告された試料を圧縮するために必要な力を、キログラム力(kgf)で記録した。物品圧縮試験の結果を、表10に記載する。
実施例及び比較例のフィラー材の繊維直径を光学顕微鏡器具(Keyence製のVHX Digital Microscope)で測定した。試料を顕微鏡下で200倍の倍率で観察し、それらの画像を撮影した。次いで、画像をスケールバーと併せて使用して、繊維の直径をミリメートルで決定した。繊維寸法を、以下の表11に列挙する。
