Method for Structuring the Surface of a Synthetic Fiber, Device for Carrying Out Said Method, and Fiber With All-Around Laminar Profile

摘要

In a method for structuring the surface of a synthetic fiber, a substantially cylindrical fiber ( 2 ) is provided with a predefined surface structure ( 38, 38 a, 38 b) by means of plastic deformation. A fiber ( 2 ) that is supplied in a plastically deformable state is plastically deformed in an embossing process by means of a micro-lithographically structured embossing roller ( 28 ) having a maximum structural fineness of 10 mum and is then transferred into a rigid state while the created surface structure ( 38, 38 a, 38 b) is maintained.
