The Influence of Hydrophobicity Factor on Wool Fibre Dyeing With Anionic Dye
In this study two alkylphenolethoxylates with different ethoxylation degree c.a.EO 9 (Lanasan LT as NPE-1) and EO 40 (Disponil AA P43 as NPE-2) were selected with the purpose to evaluate the influence of hydrophobicity of nonionic surfactants on wool dyeing efficiency.Anionic C.I.Acid Orange 7 dye was used to carry out an experiment in dyeing of wo
