A面に、単繊維繊度が1.45dtexで長さが51mmのカチオン可染ポリエステル繊維100質量%からなる40番紡績糸単糸を用いた。また、B面に、単繊維繊度が2.5dtexで長さが51mmのメタアラミド繊維95質量%と単繊維繊度が2.2dtexで長さが51mmのレーヨン繊維5質量%の混紡率からなる40番紡績糸単糸(混紡糸)を用いた。実施例1と同様にして布帛(二重織物)を作成し、同様の色に染色した。染色した布帛について、難燃性、高視認性、耐光性および風合いについての特性の測定結果を、表1に示す。
また、これらの実施例1~5で得られた布帛は、ISO 20471規格に規定される色度座標内の蛍光イエローに輝度率βが0.70以上で染色可能であり、ISO 105-B02によるキセノン耐光試験後も上記の色度座標内を維持しISO 20471規格の要求事項を満たすことを確認した。
さらに、実施例1~5の布帛は、JIS L 0842に規定されるカーボンアークによる耐光堅牢度試験でも4級を満たすとともに、風合いも普通以上であった。耐光堅牢度および風合いの観点から、布帛のB面であっても耐光堅牢度および風合いに劣るアラミド(比較例3)を用いることが不適であることが確認できた。
