Liposomes are lipid vesicles that are composed of amphiphile molecules and can carry hydrophobic and hydrophilic materials. In this research work liposomes used as carrier for transfer of dye molecules into wool fibers. The preparation and production of multilamellar liposomes (MLV) from Soya lecithin were carried out and the behavior of liposomes at different temperature was studied. The effect of different concentration of liposomes in the dye exhaustion profile of two dyes (Namely, Irgalan Blue FBL and Lanaset Blue 2R) at two different temperatures of 85 degrees C and 95 degrees C on the wool fabric was investigated. The results showed that presence of liposomes in the dye-bath helps to increase the dye absorption on the wool fabric before 80 degrees C. Dyeing at higher temperature and longer time leads to a decrease in the final exhaustion along with increase in the liposomes concentration. Liposomes at high temperature converted to the disperse phospholipids unimers that may deposited on the fabric surface and may produce a hydrophobic barrier against absorption of dye. The presence of 1% o.w.f. (on weight of fabric) of liposomes at 85 degrees C improved the dye exhaustion of Irgalan Blue FBL on the wool fabric. The wash fastness properties of samples which dyed in the dye-bath containing liposomes also improved.
