Abstract
Description
【発明の詳細な説明】 の発明は、以下の実施例に限定されるものでない。[Detailed description of the invention] The invention is not limited to the following examples.
第１図のごとく、連続的にニードルパンチ加工されたス
タンピングクロスを抗油剤の濃度が２％なるよう調合さ
れた液槽に浸漬し、絞り込んだ後乾燥炉で乾燥させたと
ころ、撥油剤の含有量２重量％のスタンピングクロス原
反を得られた。As shown in Figure 1, a stamping cloth that had been continuously needle-punched was immersed in a liquid bath containing a 2% oil repellent, squeezed, and dried in a drying oven. A stamping cloth original fabric having an amount of 2% by weight was obtained.
この原反を用いて、常法によりフードインシュレータを
成形し、フードパネルに装着した。Using this original fabric, a hood insulator was formed by a conventional method and attached to a hood panel.
このフードインシュレータを装備した車両と溌油剤の未

たところ、数回の走行により、インシュレータそのもの
の外観が、未処理のものの場合に目だった汚れとなって
いたのに対し、処理したものは、初期の汚れがない状態
を保持していた。When we compared a vehicle equipped with this hood insulator with a vehicle equipped with a hood insulator that had not been treated with oil repellent, we found that after driving several times, the appearance of the insulator itself had become noticeably dirty compared to the untreated one. On the other hand, the treated ones retained their initial stain-free condition.
また、処理と未処理で装着初期のインシュレータの吸音
性能、および同一走行距離（走行距離１０万ｋＩＴＩ）
を走行した後のインシュレータの吸音性能を比較したと
ころ、以下の第４図のグラフに示す結果を得られた。In addition, the sound absorption performance of treated and untreated insulators at the initial stage of installation, and the same mileage (mileage 100,000 km ITI)
When the sound absorption performance of the insulators was compared after driving on the road, the results shown in the graph of Figure 4 below were obtained.
この結果から明らかなように初期吸音特性は未処理のほ
うが若干高いが、経過後の吸音特性は急激に落ちている
。As is clear from these results, the initial sound absorption properties are slightly higher in the untreated case, but after the treatment, the sound absorption properties drop rapidly.
これに対し、本発明では、１０万ｋｍ走行後でも初期状
態の吸音性能とほぼ同等の吸音性能を維持し、十分な効
果があることが示唆されている。On the other hand, it is suggested that the present invention maintains sound absorption performance substantially equivalent to the initial sound absorption performance even after traveling 100,000 km, and is sufficiently effective.
