LécithineLa phosphatidylcholine est plus connue sous le nom lécithine.
Au sens le plus strict, la lécithine désigne uniquement les phosphatidylcholines c'est-à -dire un lipide formé à partir d'une choline, d'un phosphate, d'un glycérol et de deux acides gras (figure). Dans ce contexte, il serait plus juste de parler des lécithines, car il ne s'agit pas d'une seule molécule mais d'un groupe dont la composition en acide gras varie d'une molécule à l'autre. Ainsi, les lécithines vont adopter diverses couleurs selon leur composition : du jaune, pour la lécithine végétale, au brun, pour la lécithine de poisson.
Le terme de lécithine est aussi utilisé par extension pour désigner l'ensemble des phospholipides extraits du vivant (par exemple le soja), dans la mesure où ils sont majoritairement constitués de phosphatidylcholine.

| Résumé : |
The aim of this study was to examine the use of liposome in the dyeing of wool and mohair fibres with acid dyestuffs. Soybean lecithin and cholesterol were used to form the liposome membrane utilised in the dyebath. Liposome production was performed according to the thin lipid layer method (Bangham Method) using a rotary evaporator. Two different forms of liposome were used for dyeing wool and mohair fibres. In its first form, liposome was utilised as an auxiliary agent, where it was added to a conventional dyebath at the beginning of the process. In its second form, dyes were encapsulated with liposome and then used in dyeing. The effects of these two different forms of liposome were compared with conventional dyeing. Dyeing was carried out at depths of shade of 0.5%, 1.0% and 2.0% using three different concentrations of liposome (0.33%, 0.66% and 1.33%). An analysis of K/S values, fastness to washing, and the alkali solubility of fibres was conducted. The fibre samples dyed in the presence of liposome exhibited very good fastness to light (grade 8). The wash fastness test results of the liposomal-dyed samples were significantly better (grade 4-5) than for those samples which were conventionally dyed. In the presence of liposome, the tensile strength of fibres was 20 gf, whereas it was 11 gf without liposomes. |
