Abstract :In this study, electroless copper plating on polyester fabric using glyoxylic acid and potassium ferrocyanide insert ignore into journalissuearticles values(K4Fe insert ignore into journalissuearticles values(CN); 6); as reducing agent and brightener agent, respectively. Influence of concentration of potassium ferrocyanide insert ignore into journalissuearticles values(K4Fe insert ignore into journalissuearticles values(CN); 6); in the plating solution on the deposited rate, morphology and surface resistance of copper plated polyester fabrics were studied. It was found that the deposition rate significantly decreased with the rise of the concentration of K4 Fe insert ignore into journalissuearticles values(CN);6 and the copper deposits became more compact and smoother. The copper coating on the fabric exhibited a face centered cubic crystal structure. The surface electrical resistance of the obtained copper plated fabric was 13.8 mΩ/sq when 20 mg/L K4Feinsert ignore into journalissuearticles values(CN);6 was added in the plating solution. The copper plated fabric possesses excellent electrical conductivity
