A novel approach for Apocynum venetum/cotton blended fabrics modification by cationic polymer nanoparticles

Apocynum venetum/cotton blends were treated with nanoparticles followed by dyeing with Acid Red B. The results indicated that the 0.5 g/L nanoparticles concentration, 60 min treating time, 60 °C treating temperature and pH 6-8 are the optimum modification process to improve the dyeability, and the SEM images showed that nanoparticles can be adsorbed on the surface of modified A. venetum or cotton fibers uniformly.
