The use of two different types of liposome suspensions (multilamellar vesicles, MLV, and large unilamellar vesicles, LUV) as carriers in the commercial dyeing of untreated wool with a milling acid dye is described. Liposomes prepared with egg phosphatidylcholine and containing the dye CI Acid Blue 90 were used. The physico‐chemical stability of liposomes was studied by measuring the mean particle size distribution of phospholipidic vesicles during dyeing. The possible hydrolysis of phospholipid molecules was also determined. Kinetic aspects involving dye adsorption and bonding were investigated. Dye exhaustion on untreated wool fibres was inhibited and dye bonding was improved. The lipid concentration and type of liposomes were important factors in this process.
