There is disclosed an acid and disperse dyeable polyolefin composition consisting essentially of from about 80-98% by weight of a polyolefin, from about 1-10% by weight of a N-vinyl-2-pyrrolidone polymer having a moisture regain, measured at 37.8 DEG C and 98% relative humidity, of at least 10% and a ratio of mole fraction of N-vinyl-2-pyrrolidone units in the polymer to moles of water regained for 100 g of polymer of from greater than 0:1 to about 0.3:1, and from about 1-10% by weight of a polyamide having tertiary amine nitrogen atoms, <IMAGE> where all three carbon atoms are saturated, said polyamide being normally a solid at 22 DEG C, melting at a temperature of 235 DEG C or below, and having a structure number, N, as defined herein, of from 10-18. At least 25 mole % of all units in the polyamide have a basic tertiary amine nitrogen atom. There are also disclosed a method of preparing a preferred embodiment of the composition of the invention, filaments prepared from the polyolefin composition and woven and nonwoven sheets prepared from the filaments.
