摘要：
In a crimping process of metal fibers between the engaging pairs of gear rollers, the fibers are first embedded in a ductile and coherent matrix material. After applying a permanent crimping wave deformation on this composite, the matrix material is removed. The crimped fibers can subsequently be transformed to a metal fiber web. They can also easily be blended with textile fibers in order to form, e.g., antistatic blended yarn.
