Use of pro-liposome compositions in the textile finishing and process for preparing dyeing bath based on said pro-liposome compositions

摘要

The pro-liposome composition confers greater efficacy in dyeing due to greater penetration of the dye into the fabric fibres. In bleaching, the humectant capacity of the liposomes formed enhances the degree of final bleaching. In smoothing, the addition of the pro-liposome composition permits replacement of the substances normally used, thereby providing savings in raw material and reduction of the final pollutant content of the bath. The method consists in mixing the pro-liposome composition with the colorant(s) and the pre-heated water; stirring the mixture until homogeneity is achieved; separately, mixing sulphuric acid and pre-heated water; mixing the above resulting mixtures and proceeding to bathing of the fabric to be dyed.
