(5)撥水性(撥水ころがり角度)
水平板上に取りつけた平面状の被測定試料に0.2ccの水を静かに滴下し、この平板を等速度で静かに傾斜させ、水滴がころがりはじめるときの角度を撥水ころがり角度とした。なお、撥水ころがり角度が小さいほど撥水性が良好であり、25度以下を合格とする。
(6)撥水度
JIS L1092-2009 7.2 はっ水度試験(スプレー法)により撥水度(級)を測定した。
(7)織物の目付け
JIS L1096-2010 8.3により織物の目付け(g/m2)を測定した。
ポリエチレンテレフタレートを紡糸温度300℃で紡出し、4000m/minで引き取り、一旦巻き取ることなく引き続き1.3倍に延伸し、フィラメントの横断面形状が丸断面のポリエステルマルチフィラメント70dtex/144fil(非捲縮繊維からなる極細繊維)を得た。
