A self-crimping multi-component polyamide filament is provided and a process for producing the filament. In its simplest form, the filament is composed of two components each of which comprises a polyamide of the same chemical composition and one of which contains a minor amount of a polyolefin admixed with the polyamide. The filament is formed by co-extruding the components to form a conjugate filament that is attenuated in the molten state, solidified and then collected. Attenuation of the filament in the molten state imparts self-crimping properties and molecular orientation to the filament.
