ABSTRACT OF THE DISCLOSURE An acid and disperse dyeable polyolefin composition is provided consisting essentially of from about 80-98% by weight of a polyolefine; from about 1-10% by weight of a N-vinyl-2-pyrrolidone polymer having a moisture regain, measured at 37.8°C and 98% relative humidity, of at least 10% and a ratio of mole fraction of N-vinyl-2pyrrolidone 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 poly- amide being normally a solid at 22°C, melting at a temperature of 235°C or below, of from 10-18, at least 25 mole % of all units in the polyamide having a basic tertiary amine nitrogen atom. Also disclosed are methods of preparing the polyolefin compo- sition, filaments prepared from the composition and woven and nonwoven sheets prepared from the filaments.
