fibers is even less, our group once successfully prepared Ni–P plated wool using chitosan as good media to chelate metal ions [9]. Herein, we propose a novel method to produce silver plated wool fibers by chemical bonding of silver layer and fibers without the usage of noble metal catalyst [10]. Firstly we utilized TCEP to produce –SH groups the wool fiber [11], which will act as seeds to connect with silver ions together with other natural functional groups like –NH2 and –OH in the wool fibers [12]. After metallization process, the plated silver layer
