To provide a polyester product, such as a new advertising curtain and a banner having excellent flame retardancy.

The polyester products, such as the advertising curtain and the banner having the flame retardancy comprise preparing a flame retardant (HBCD) for a polyester fabric, subjecting the fabric to a setter process to cause permeation fixing of the thus impregnated flame retardant into the yarn of the fabric at a high temperature, printing and displaying a prescribed display surface on the resultant fabric based on the silk printing using an existing flame retardant pigment ink, and subjecting the fabric to cutting processing and sewing processing etc., thereby perfecting the polyester products.
