Description
1組のハードテンションD’Addario複合体(PEEK)クラシック弦(部品番号EJ46C)からの巻クラシック弦を、UV硬化性樹脂を吸収させたフィルムで被覆した。この組は、直径の異なる3本の巻き弦から成るものであった。以下に、それぞれの弦とその個々のD’Addario部品番号について記載する。
2番目の組の巻きクラシック弦をD’Addario(部品番号EJ46C)から入手し、使用した溶媒/樹脂溶液を以下のように変更したこと以外は、例1で記載されるのと実質的に同様の方法で被覆した。単位面積当たりの質量が約1.1g/m2で、厚さが0.0025mmの延伸PTFEを、デラウェア州、ニューアークのW.L.ゴア・アンド・アソシエーツ社から入手した。このフィルムの多孔度は約80%であった。75/25wt%のMEK溶媒/樹脂溶液を、延伸PTFEフィルムに吸収させるため調製した。この樹脂は、コネチカット州、トリントンのDymax社によって製造されている621シリーズ MULTI−CURE(登録商標)ウレタンアクリレートであった。この溶媒−樹脂溶液を、延伸PTFEフィルム全体に投与し均一に塗布した。ライナーを、溶媒−樹脂溶液を延伸PTFEフィルムに浸透させたフィルムと組み合せた。ライナーと吸収フィルムの両方を炉(約125℃に設定)に通して送り、MEK溶媒を除去した。フィルムを炉から取り出し、フィルムのライナー表面と一致して吸収された樹脂と、ライナー側に存在する薄い表面コートとを有する部分的な吸収構造体を回収した。この表面コートは、延伸PTFE表面のすべてではないがその一部を被覆していた。吸収フィルムは、厚さが約0.0024mmと測定された。吸収フィルムの単位面積当たりの質量は約1.8g/m2と測定された。
(デラウェア州、ニューアークのW.L.ゴア・アンド・アソシエーツ社から入手した)延伸PTFEのフィルムに、NEOFLON(商標)RP−4020EFEP(エチレンテトラフルオロエチレン系コポリマー、ダイキン工業社製)をコーティングした。このコーティングは、延伸PTFE基材の一方の表面にNEOFLON RP−4020EFEPの層を接触させることにより行った。このアッセンブリをNEOFLON RP−4020EFEPの融点よりも高い温度に加熱し、次いでその温度を維持しながら伸長した。次に、このアッセンブリを冷却して、NEOFLON RP−4020EFEPをコーティングした延伸EPTFEのフィルムを得た。次に、このフィルムを約4mm未満の幅に細長く切り、下の各D’Addario弦の周囲にらせん状に巻きつけて弦の長さ全体にわたって2層のフィルムを形成した。
熱可塑性フルオロポリマーのDyneon(商標)HTE(ヘキサフルオロプロピレン、テトラフルオロエチレン、エチレン)を用いた以外、本質的には比較例1を繰り返した。炉から取り出すと、すべての弦が脆かった。これらの弦を比較例1と同じクラシックギターに取り付けたが、音は許容できないものであった。
(デラウェア州、ニューアークのW.L.ゴア・アンド・アソシエーツ社から入手した)延伸PTFEのフィルムに熱可塑性フルオロポリマーのDyneon(商標)HTE(ヘキサフルオロプロピレン、テトラフルオロエチレン、エチレン)をコーティングしたものを、本質的に比較例1に記載されるようにして作製した。次いで、比較例1に詳述する通り、このフィルムを23本のD’Addarioクラシック弦(部品番号J4604C)に適用した。
(デラウェア州、ニューアークのW.L.ゴア・アンド・アソシエーツ社から入手した)延伸PTFEのフィルムに熱可塑性フルオロポリマーのTHV(テトラフルオロエチレン、ヘキサフルオロプロピレン及びフッ化ビニリデン)をコーティングしたものを、本質的に比較例1に記載されるようにして処理した。次いで、比較例1に詳述する通り、このフィルムを7本のD’Addarioクラシック弦(部品番号J4604C)に適用した。
本例では、例1に従って形成した被覆弦の耐久性を、例3及び例4で形成した被覆弦と比較する。
