Abstract
A method for self-crimping of S/S bi-component fibers on a fiber line includes the steps of main drawing, post-drawing on a cold drawing unit, water application in the tensed state and relaxation at the dryer inlet in the compact closed state, which results in fibers with a novel .OMEGA.-shaped crimping structure.
