Description
本発明においては、熱可塑性樹脂からなる形状保持材が用いられる。
本発明において、「形状保持材」とは、塑性変形性を有する材料を意味し、任意の形状に変形させた際に塑性変形性により実質的にその形状を保持しうる性質を有する材料をいう。
図1は本発明に係るスリッパの一例を示す模式斜視図であり、1は底部、2は覆甲部、3は形状保持材を示す。
重量平均分子量(Mw)3.3×105、融点135℃の高密度ポリエチレン(日本ポリケム社製)を同方向二軸混練押出機(プラスチック工学研究所社製)に供給して樹脂温度200℃で溶融混練した後、Tダイを用いてシート状に吐出し、吐出されたシート状の溶融混練物をロール温度110℃に制御したカレンダー成形機にて幅25mm、厚さ9.5mmのシートに成形してポリエチレン樹脂シートを得る。
2 覆甲部
3 形状保持材
4 開口部
Claims (3)
- 塑性変形性を有し、任意の形状に変形させた際に塑性変形性により実質的にその形状を保持しうる性質を有する、熱可塑性樹脂からなる形状保持材が覆甲部に埋設又は貼着されて用いられたことを特徴とするスリッパ。
- 形状保持材が覆甲部及び底部に埋設又は貼着されて用いられたことを特徴とする請求項1記載のスリッパ。
- 形状保持材が、延伸倍率10〜40倍の延伸オレフィン系樹脂シートからなることを特徴とする請求項1又は2記載のスリッパ。
