Abstract: In this thesis, the research work mainly focused on the preparation of nano-scale chitosan, and its applications in textile. Firstly, a new method to prepare the emulsions containing chitosan nanoparticles was developed through a dissolving-precipitating-dispersing process with the assistance of ultrasound, and emulsions of the pure chitosan nanoparticles or the composite chitosan/silver oxide nanoparticles were accordingly prepared. Then the emulsions were studied in the applications of textile antibacterial and deodorizing finishing. On the other hand, research works was done on the investigation and applications of the pure chitosan nanoparticles in the dyeing process of textile. This section included the study of the interaction between the pure chitosan nanoparticles and the acid dye molecules, and the application of the emulsion of the pure chitosan nanoparticles on the dyeability improvement of silk fabrics and nylon fabrics.
