The Dyeing of Polypropylene Fibers with Disperse Dyes

The Journal of the Society of Chemical Industry, Japan, 1962
ポリプロピレン繊維に対する分散染料の水分散系における染着について染着平衡の立場から検討した。まず,分散剤の影響を避けるために,極性の大きい3種類の精製アントラキノン系染料,C.I.Disperse Blue 3,Blue27およびViolet11を選び,分散剤を添加しない染色系での染着平衡を測定した。染着平衡は,分配型の直線関係を与え,ΔH0およびΔS0ともに正の値を示した。また,これら染料のトリプロピレン/水の分配平衡は染着平衡と併行性を示し,トリプロピレンによく溶解する染料ほどポリプロピレン繊維に対して大きい親和性を有する。上記,染色系に分散剤としてアニオンおよび非イオン活性剤を添加することにより,染着量の低下をきたすだけでなく ...
