Abstract

Process for manufacturing a bulky composite fiber having a curling frequency of more than 10 curls per 25 millimeters, a degree of curling of at least 15% and a Young's modulus of at least 80 g/d, characterized in that extrusion and stretching form a composite fiber from two or more polymeric acrylonitrile components that have different shrinkage behaviors, said components being arranged eccentrically along said fiber, finally being dried tension-free at a temperature lower than 80º C.
