Abstract:

In order to better apply nano silver to the functional finishing of textiles, the preparation methods of nano silver and the characteristics of various methods to obtain nano silver in recent years are systematically introduced. The preparation methods mainly including liquid chemical reduction, photochemical synthesis, electrochemical synthesis, biosynthesis and microwave assisted method. At the same time, the research progress of nano silver in the field of textiles is reviewed, when nano silver were utilized in the textiles, it can endow textile with antibacterial, UV protection, self- cleaning, hydrophobicity, electromagnetic shielding and antistatic properties, and the mechanism of nano silver to realize these functions is elaborated in detail in order to promoting the industrialization development of nano silver in the field of multifunctional textiles. Finally, the problems existing in the application of nano silver on textiles are further analyzed and summarized, and the prospect of its application in textiles is forecasted.

Key words: nano silver, antibacterial textile, functional finishing, electromagnetic shielding property
