A method for manufacturing filaments for personal hygiene articles is described. The filaments are provided with a surface structure with at least one surface recess such as dimples and/or pittings. The filament includes at least a portion made of a material soluble by a corrosive agent and is covered in part with a cover layer stable to the corrosive agent such that a surface portion of the filament body substantially corresponding to the at least one surface recess is uncovered. The filament body is contacted with the corrosive agent for a limited time to create the surface recess in the uncovered surface portion.
