Wool dyeing process
Phospholipids combination from commercial soybean lecithin (SBL) had been prepared as acetone insoluble small fraction (AIF) which was acetylated at 70per cent. Phospholipids composition was elucidated with TLC-Densitometry. The acetylated AIF had been used for planning liposomes for encapsulating reactive dye for wool and wool combinations dyeing. Ultrasonic irradiation was utilized in organizing liposomes. Particle dimensions measurements associated with the liposomes encapsulating the dye at different concentrations had been measured. Optimum particle measurements of about 16 nm was gotten at liposome concentration of 4 g/l.
Dyeing was performed under different parameters in presence and lack of microencapsulated (MS) dye. Along with energy values, exhaustion, levelling and fixation per cent had been greater in presence of liposome and tensoactive product compared to those of old-fashioned dyeing process. These more satisfactory link between wool dyeing encouraged the application of the maximum problems of wool dyeing on wool combination fabrics with effectiveness dye uptake and levelling. Furthermore, microencapsulation with liposomes as a brand new efficient technology for dyeing procedure prevents environmental air pollution.
