PURPOSE: A method for processing expanded foam of a polyester fabric is provided to express unique patterns and soft exterior or texture. CONSTITUTION: A method for processing expanded foam of a polyester fabric comprises: a step of preparing a processing solution containing 8.0-12.0 wt% of polyvinyl alcohol resin, 2.0-8.0 wt% of surfactant, 1.0-10.0 wt% of foaming agent, 1.0-5.0 wt% of acrylamide copolymers, 0.5-2.0 wt% of thickening agent, 0.2-1.0 wt% of anti-foaming agent, and remaining amount of water; a step of printing the processing solution on the polyester fabric; and a step of thermal-setting of the polyester fabric at 160-170 Deg. C. for 40-120 seconds, washing, and drying. The foaming agent contains 30-45 wt% of azodicarbonamide, 20-25 wt% of p,p'-oxybisbenzensulfonylhydrazide, 15-20 wt% of p-toluenesulfonylhydrazide, 15-18 wt% of azobisisobutyronitile, and 5-7 wt% fo dinitropentamethylene tetramine. |
