各試験の評価結果は、下記表2中に示した。
白色度の評価は、評価用の繊維のL*値を測色することにより行った。測色機としてはX-Rite社製のeXactを用いて、CIE/L*a*b*表色系における、L*値を測色した。このときの測色条件は、観測光源がD65、観測視野が2°、濃度がStatus Tであった。各評価用の繊維に対して5回測色を行い、その平均値を測定結果とした。L*値は大きい程、高い白色度を示すため好ましい。
評価用の繊維を、繊維が破れない程度に両手で限界まで延伸し、3秒間保持した後、延伸を止めた。その繊維の白色のベタパターン画像のヒビ割れを目視で観察し、その状態を下記3段階の評価基準で評価した。
-評価基準-
A:画像には延伸によるヒビ割れが認められなかった。
B:画像は延伸により僅かにヒビ割れし、生地の色である黒色が僅かに観察された。
C:画像は延伸によりヒビ割れし、生地の色である黒色が明確に観察された。
評価用の繊維の白色のベタパターン画像を目視で観察し、画像ムラを下記3段階の評価基準で評価した。
-評価基準-
A:画像にはムラが認められなかった。
B:画像には僅かにムラが認められ、白色ではあるが濃淡が生じている部分があった。
C:画像にはムラが認められ、白インクが過剰に付着してしまった部分や、白インクが付着せず、生地の色である黒色が明確に観察される部分があった。
下記表3に記載の成分を十分に撹拌して混合し、白インクを得た。得られた白インクを孔径5μmのミックスセルロースエステルのフィルターで濾過した後、真空ポンプを用いて脱気処理することにより、試験用の白インクW1、W2を得た。
