In pretreatment processing of textile materials Liposomes can be used in textile pretreatment processing as washing and scouring agents. They are generally stronger detergents in removing contaminants than traditional surfactants. Another advantage is that liposomes have low foam tendency during washing process. In addition, liposomes exhibit strong potential in bleaching. The introduction of liposomes into bleaching bath compositions favors strong deceleration of hydrogen peroxide decomposition, and simultaneously improves properties of fabrics, such as mechanical properties, brightness, softness, load, and elongation at break. In dyeing processing Liposomes can serve as delivery vesicles to transport encapsulated dyes to wool and polyether fibers. Their interaction with wool is affected by liposome absorption and lipid solubilization in wool, which leads to a deeper penetration of the dye to wool fiber. Modification of lipids in liposome may greatly enhance the dyeing efficiency and diffusion properties of wool fiber, resulting in shorter processing time, reduced dyeing temperature and better color stability.
