A durable water/oil-repellent fabric with excellent wrinkle resistance via non formaldehyde crosslinking agent was developed. Therefore, this paper investigates effect of non-formaldehyde cross-linking agent based on polyurethane in the presence of fluorocarbon and nano-silica compounds on water/oil repellency and the durability of treatments on cotton fabric. The cotton fabric was first treated with cross-linking polyurethane, and then treated fabric was placed in a silica-fluorocarbon ultrasonic bath, via pad–dry–cure method. Sample 4 (CPN 6%, nano-silica of 1%, FB of 8%) showed the best results, and the contact angle reached 130 degrees. The water/oil repellency was reduced by three washing and returned to the original value after heat treatment. Cross-linked fabrics reached an excellent crease recovery angle of 234 degrees. EDS of sample 4 shows the presence of F and Si on the fabric. With washing, the amount of fluoride decreases and bounces back after heat treatment. SEM analysis shows increase on surface roughness. ATR analysis shows peaks corresponding to Si–O, carbon bonds or amide related absorption peak and C = O on treated fabric.
