PROBLEM TO BE SOLVED: To obtain a polyester fibrous structure capable of simultaneously satisfying high levels of weather resistance and flame retardance without deteriorating physical and chemical characteristics essential to a polyester fiber by adsorbing a specific ultraviolet light absorber and a specified flame retardant thereon. SOLUTION: This polyester fibrous structure is obtained by respectively adsorbing >=0.2% at least one ultraviolet light absorber represented by formula I (R is H or a lower alkyl; R1 and R2 are each a lower alkyl), formulae II and III (R is a lower alkylene) and having >=10% sublimation weight loss at 220 deg.C and >=0.4% at least one flame retardant represented by formula IV, formula V [R1 and R2 are each a lower alkyl; R3 and R4 are each H or a lower alkyl; Y is CH2 , C(CH3 )2 , S, SO2 , O or CO-N=N; (m) is an integer of 0-4], formula VI, etc., on a spun-dyed polyester textile fabric and imparting weather resistance and flame retardance thereto. |
