染色工程におけるウレタン樹脂の皮革様シートからの脱落の有無を評価するにあたり、その代用試験として、染料を含まない水を染色液として用い評価を行った。前記ウレタン樹脂の脱落は、水及びその温度の影響によるものであるから、前記評価方法により、染色工程におけるウレタン樹脂の脱落の評価方法に代用することが可能である。
前記脱落率が0質量%以上2.5質量%未満であったものを「A」と評価し、2.5質量%以上5.0質量%未満であったものを「B」と評価し、5.0質量%以上7.5質量%未満であったものを「C」と評価し、7.5%以上であったものを「D」と評価した。また、ウレタン樹脂を水性媒体中に分散することができずゲル化したため、前記皮革様シートを製造できなかったものを、表1及び2中「−」と評価した。
実施例及び比較例に記載の方法で、各ウレタン樹脂が水性媒体に分散したウレタン樹脂組成物を製造できたものを「A」、ウレタン樹脂が水性媒体に分散せず、沈降またはゲル化したものを「D」と評価した。
前記方法で得たウレタン樹脂組成物の不揮発分が20質量%となるように調整したものを、粘度・粘弾性測定装置(HAAKE社製、Reo Stress)を用い1℃/minの条件で加熱しつつ、その粘度を測定した。その粘度が100mPa・sを超えたときの温度を凝固温度とした。また、90℃以上に加熱した場合であっても前記粘度が100mPa・sを超えなかったものを「凝固せず」と評価した。
前記方法で得た繊維積層体の柔軟性(風合い)を、触感により下記評価基準にしたがって評価した。
