The application of poly(amidoamine) dendrimers for modification of jute yarns: Preparation and dyeing properties

In this study, poly(amidoamine) (PAMAM) G-2 dendrimer was used for jute yarn. Fourier transform infrared spectroscopy (FT-IR) revealed that all carbonyl groups of jute fibers reacted with amino groups of polyamidoamine dendrimers. SEM observation indicated the good dispersion PAMAM dendrimers. Jute yarns pretreated with PAMAM dendrimer displayed markedly enhanced color strength with reactive dyes, even when dyeing had been carried out in the absence of electrolyte or alkali. Dendrimer-treated jute yarn showed much better light-fastness than untreated jute yarn.
