DYEING BEHAVIOUR OF TREATED WOOL WITH SOME METAL IONS

Interaction of metal ions with wool is currently studied. The absorption of some metal ions such as copper, iron, cobalt, nickel and aluminum by wool from their aqueous salt solutions is investigated. The treatment conditions such as temperature of treatment and the pH values of metal salt solutions are interpreted. The effect of pretreatment of wool with some di- carboxylic acids on the metal uptake by wool is given. The influence of these absorbed metal ions on the dyeing properties of wool is investigated. The mechanical properties, alkali solubility, fastness properties as well as kinetic investigation on the dyeing process are also investigated.
