The dyeing properties of wool fiber pretreated with benzyl alcohol was investigated. The dyeing experiments were preferred using C.I Acid Orange 7 at 80℃, pH 4.2.
The dye uptake of pretreated wool was increased compared to that of scoured wool. The increase of dye uptake of pretreated wool is attributed to the removal of scale which is the surface barrier of dye diffusion.
The dye uptake is changed with pretreatment temperature and time of benzyl alcohol. The action of benzyl alcohol on solvent-assisted dyeing is considerably due to some of disaggregation of dye in aqueous solution.
