This review discusses the properties of liposomes and their role in the textile process, including textile preparation and dyeing. Liposomes have a surface activity effect due to a hydrophilic head group and hydrophobic hydrocarbon tail. Its preparations do not tend to foam, which advantageously distinguishes them from other textile auxiliaries. According to the carrier role of liposomes, they can be used in several textile processes such as textile finishing and dyeing with several types of dyes and fibers. Each application is discussed in this review paper. Several types of dyes are encapsulated by liposomes in the dyeing process and their presence indicates that they have retardant and leveling effects according to their gradual release of dyes. In addition, the presence of liposomes in the textile process can improve the mechanical properties of textile products, resulting in better wash fastness properties and leveling effect and handle properties. The best character of liposomes is a reduction in temperature of process resulting to save energy and they are environment degradable materials.

The environmental safe treatment methods were used to improve the penetrability of wool fibers with natural dye (Madder) in the presence of chemical and physical modified natural soybean lecithin. The dyeing conditions of wool fiber with madder were optimized by response surface methodology (RSM). The five independent variables were selected at low and high level values. The ANOVA results of the quadratic model show that the model terms such as dyeing temperature, dyeing time, lecithin concentration, plasma treatment duration, dyeing method, and their interactions are significant. Moreover, the optimum conditions which were proposed for the natural dyeing of LTP-treated wool fibers cause dyeing temperature reach to 76.53°C in the presence of acetylated lecithin.
