New generation of liposomic products with high migration properties

The usefulness of liposomes made up of phosphatidylcholine for wool dyeing has already been demonstrated. The dyeing temperature can be 10degreesC lower than for conventional dyeing, with similar dye exhaustion and lower environmental impacts. However, conventional liposomes do not favor dye migration and do not achieve good leveling without synthetic auxiliaries. This work presents new strategic liposome formulations to increase migration phenomena in wool fabrics and yarn dyeing. The promising results obtained with these specific liposome formulations are compared with those using a number of commercial migrators such as Tanapal LM and Albegal SET in wool fabric dyeing with premetallized 2:1 (Lanaset) and 1:1 (Neolan) dyes.
