JIS L1055 A法(2003年版)に準拠して、遮光率を測定した。
紫外線遮蔽率試験方法は、紫外線カット素材の加工効果統一評価方法(日本化学繊維協会)に準じ測定した。分光光度計(株式会社島津製作所製UV−3600、付属装置として、マルチパーパス大型試料室MPC−3100(積分球付)を用い、波長280〜400nmの透過率を測定し、これの積分値を求め、次式で算出した遮蔽率によって紫外線カットの効果を判定する。
温度20±2℃の試験室内において、黒画用紙の5mm上にスペーサを用いて試料を保持し、試料上部50cmからレフランプ(岩崎電気株式会社製アイランプ<スポット>PRS100V500W)でランプ光を照射して、15分後の黒画用紙裏面の表面温度をサーモカメラ(NEC Avio赤外線テクノロジー(株)製H2630、一般財団法人カケンテストセンター)で測定した。測定は生地の位置を入れ替えて4回測定し、そのデーターを平均した値を試験結果とした。
総繊度56デシテックス72フィラメントのポリエステル仮撚加工糸をツイル組織で製織し、通常の染色加工工程、即ち、精練後、130℃の温度での液流染色と160℃の温度の仕上げ熱セット工程を経て、タテ糸の密度が176(本/2.54cm)で、ヨコ糸の密度が118(本/2.54cm)のカバーファクター2200の織物を得た。
繊維布帛として、実施例1記載のカバーファクター2200の織物生地を使用した。
総繊度56デシテックス48フィラメントのフルダルポリエステル糸を平組織で製織し、通常の染色加工工程、即ち、精練後、130℃の温度での液流染色と160℃の温度の仕上げ熱セット工程を経て、タテ糸の密度が162(本/2.54cm)で、ヨコ糸の密度が116(本/2.54cm)のカバーファクター2080の織物を得た。
実施例1の繊維布帛と、全体の質量パーセントで7%の酸化チタンを添加した合成樹脂フィルムを貼り合わせ、2層シートを得た。
実施例1の繊維布帛と、実施例2の全体の質量パーセントで30%のカーボンブラックを添加した合成樹脂フィルムを貼り合わせ、2層シートを得た。
2:酸化チタンを含有する合成樹脂フィルム
3:カーボンブラックを含有する合成樹脂フィルム
