Disclosed are polytrimethylene terephthalate-based flame retardant compositions and fibrous articles produced therefrom. The flame retardant compositions comprise (a) 74 weight % to 99.4 weight % of polytrimethylene terephthalate; (b) 0.5 weight % to 10 weight % of a flame retardant, which is a phosphorous containing polyester of Formula 1, wherein n is an integer ranging from 22 to 150; (c) 0.1 weight % to 6 weight % of alumina oxide nanoparticles; and (d) 0 to 10 weight % of an optional additive; wherein the weight percent is based on the total weight of the flame retardant composition.
