二軸押出機(口径46mm、L/D=46)を用いて、下記の表3に記載の各構成成分を、表3に示す配合に従って、190℃で溶融混練することにより、ペレット状の樹脂組成物(A)を製造した。
表3に記載の各構成成分および配合比率を適用したこと、および図2に記載の微小菱形の孔の作製に代えて、図3(図中の黒色部分はスリットまたは孔を示す)に示すスリットを作製したこと以外は、実施例4と同様にして、多孔複合体(5)を得た。開孔率、異方化率、および伸張応力緩和率の測定結果を表3に示す。
表3に記載の各構成成分および配合比率を適用したこと以外は、実施例4と同様にして、多孔複合体(6)~(11)を得た。開孔率、異方化率、および伸張応力緩和率の測定結果を表3に示す。
表3に記載の各構成成分および配合比率を適用したこと、および図2に記載の微小菱形の孔の作製に代えて、図4(図中の黒色部分はスリットまたは孔を示す)に示す複数の長方形(長さ10mm、幅5mmのスリット)を作製したこと以外は、実施例4と同様にして、多孔複合体(12)を得た。開孔率、異方化率、および伸張応力緩和率の測定結果を表3に示す。
表3に記載の各構成成分および配合比率を適用したこと、および図2に記載の微小菱形の孔の作製に代えて、図5(図中の黒色部分はスリットまたは孔を示す)に示す複数の円形で縦の間隔と横の間隔が異なるメッシュ状多孔シート{径7mmの円形、縦方向の円と円の間隔(円端部と円端部の長さ)7mm、横方向の円と円の間隔4mm}を作製したこと以外は、実施例4と同様にして、多孔複合体(13)を得た。開孔率、異方化率、および伸張応力緩和率の測定結果を表3に示す。
表3に記載の各構成成分および配合比率を適用したこと、および孔を作製しなかったこと以外は、実施例4と同様にして、多孔複合体(4)’を得た。開孔率、異方化率、および伸張応力緩和率の測定結果を表3に示す。
表3に記載の各構成成分および配合比率を適用したこと以外は、実施例4と同様にして、多孔複合体(5)’~(10)’を得た。開孔率、異方化率、および伸張応力緩和率の測定結果を表3に示す。なお、比較例7において、伸張応力緩和率の測定開始より破れが発生し、また、比較例8においては、成形不可につき測定できなかった。
その後、選手10名に15分間の練習試合を行わせた。その試合中(運動時)のスポーツブラの固定安定性、締付け性および爽快性(耐ムレ性)の官能評価を選手10名により行った。10名の選手の評価の平均値を、装着性の評価として採用した。その結果を表4に示す。
ランク1:良好
ランク2:比較的良好
ランク3:普通、少し違和感あり
ランク4:違和感あり
ランク5:違和感あり、使用したくない。
