Phosphatidilcholine Liposomes as Vehicles for Disperse Dyes for Dyeing Polyester/Wool Blends

Abstract

This study describes the role of liposomes as carriers in dyeing polyester/wool blends with disperse dyes. Dye exhaustion and bonding on polyester/wool samples are studied under different experimental conditions—the liposome amount, the dye amount, and the temperature—to achieve optimal conditions. The results are compared with those obtained with and without conventional dyeing auxiliary products. Although bath exhaustion is higher in the presence of commercial carriers, the dye bonded in creases markedly in the presence of liposomes in the two fibers. The role played by liposomes in polyester/wool blend dyeing can lead to a new strategy for this process.
