Abstract
The purpose of this study is to propose the development of high quality electromagnetic wave shielding fabrics. Silver nitrate is used for polyester fabric as an electromagnetic wave shielding material. The effects of activators and electroless silver plating condition on the evenness and adhesion of silver to fabrics, are observed through the SEM micrographs. Surface morphology and wash-ability are measured using SEM. The results are as follows: The optimum weight loss by alkaline hydrolysis of polyester fabrics is about 20%. The optimum concentration of $SnCl_2$ and $PdCl_2$in catalyst reaction using $PdCl_2$ as an activator is 2.5g/L and 0.5g/L, respectively. The optimum concentration of dextrose to improve adhesion between the silver plating and fabrics is 45g/L. The optimum concentration of silver nitrate in the catalyst reaction, using $PdCl_2$ as an activator is 56g/L, respectively. The optimum plating temperature and time are $15^{\circ}C$ and 30minutes, respectively.
