Process for preparing self-curing composite acrylic fibers, by spreading at least two solutions of acrylonitrile polymer components through a single hole to form solvated filaments; desolvation of the filaments; stretching of the desolvated filaments; drying of the stretched filaments and relaxation of the removed filaments; characterized in that solutions of the same acrylonitrile polymer and of the same concentration in solution are used as the fiber-forming components, and a sufficient amount of a shrinkage-modifying additive is added to at least one of the components to effect the difference of contraction necessary to provide the self-curling character in the formed fiber.
