Abstract: Antibacterial agent KD-2015, antibacterial agent KD-9400, water-proofing agent SFA, flame retardant HHS were used for the composite functional finishing of the knitted ceiling fabric. The influences of process parameters, such as the type of antibacterial agents, the amount of waterproof agent and flame retardant, and the setting temperature, on the properties of the product were analyzed. Results indicated that: use 3% antibacterial agent KD-2015, 2% water repellent SFA, 1:6 flame retardant HHS to prepare a composite functional finishing solution, and then have a direct one-bath process. The fabric is set at 160 ℃ for 1 min. The fabric has good antibacterial, flame-retardant and waterproof properties, which can meet the needs of forming and processing of automotive ceiling fabric.
