Usage of liposomes in dyeing of alpaca and polyacrylonitrile fibers

Liposomes are known as double-layered structures consisting of phospholipids. Textile manufacturers are showing increasing interest in the use of natural products such as phospholipids in the ecological realization of their processes. Liposomes encapsulate dye molecules, preventing them from moving quickly to the fibers, thus supporting dyeing uniformity. Within the scope of this thesis study, liposome synthesis was first carried out. Successful production of liposomes was confirmed by Fourier transformed infrared spectroscopy analyses. In addition, according to the zeta potential measurements, it can be said that the %1 solution creates a more stable suspension than the other concentrations among the solutions prepared in 4 different liposome concentrations: %0,5-1-2-4. It was determined that the polydispersity index value of %1 liposome was 0,472 and the average particle size was 165,2 nm. Then, reactive and basic dyes were encapsulated with liposomes and the possibilities of using these capsules in dyeing alpaca and polyacrylonitrile fabrics, respectively, were examined. As a result of the studies, it has been revealed that if %1 liposome is used in dyeing, a kind of leveling agent effect can be obtained in the dyeing of alpaca fibers and a kind of retarder effect can be achieved in the dyeing of polyacrylonitrile fibers. However, unlike leveling agents and retarders, it has been observed that although the dye uptake slows down when liposomes are used, the final dye uptake at the end of dyeing does not decrease, on the contrary, it increases. Furthermore, there was no significant difference in terms of fastness of dyeing.
