The current approaches to prepare antibacterial fibers are applied by coating [2], pad-dry-cure [3], chemical modification [4] and electro-less plating [5] processes with metal elements [6], photo-catalytic materials [7], and qua- ternary ammonium agents [8]. Among them, hand feeling is hurt and durability of antibacterial properties is not so good by coating and pad-dry-cure. Chemical modification process can solve this problem but it does damage to fabric's mechanical strength. Silver electro-less plating is an effective way to impart substrate with antibacterial and antistatic properties with good durability.
