Sažetak
Wool samples were dyed with indigo through an exhaust technique at various pH values. The non-ionic form had the highest substantivity while the Ionics ones had relatively less for wool. The fibres could best be dyed in the acidic pH range. Chemistry of the dyebath and fibre was considered to explain the effects of pH on colour strength. The results showed that hydrogen bonding and ionic interactions were the main reason for the exhaustion of dye onto wool fibres. Hydrogen bonding was operated between the hydroxyl group and amide groups of the dye and the fibres respectively while ionic interactions worked at low pH values between the end-amino and ionized groups of the dye respectively.
