Description
次に、各サンプルに、厚み１２５μｍのフィルムを４ｋｇｆのテンションで５周巻き付けて、５０℃で４時間エージングし、常温に戻った状態でフィルムを解舒した。
フィルム解舒直後に、各サンプルの弾性体層の表面部分に形成されている段差（凹部）を測定した。
引き続いて、各サンプルにおける段差が形成されている付近の弾性体層表面部分を、加熱温度１２０℃に設定したホットプレートに、自重（約１５０ｇ）で押し付けて、加熱した。加熱は、１０秒単位で行い、その都度、加熱後の段差を測定し、段差の復元が見られなくなるまで加熱を繰り返した。
また、フィルム解舒後２０時間以上経過した各サンプルについて、上記と同様の段差復元確認テストを行った。
Next, a 125 μm-thick film was wound around each sample for 5 turns with a tension of 4 kgf, aged at 50 ° C. for 4 hours, and the film was unwound after returning to room temperature.
Immediately after the film was unwound, the step (concave portion) formed on the surface portion of the elastic layer of each sample was measured.
Subsequently, the surface of the elastic body layer in the vicinity of each sample where the step was formed was pressed against a hot plate set at a heating temperature of 120 ° C. with its own weight (about 150 g) and heated. Heating was performed in units of 10 seconds, each time a step after heating was measured, and heating was repeated until no restoration of the step was observed.
Also, for each sample for at least 20 hours after the film unwinding, it was subjected to the same step restoration confirmation test as described above.
