Abstract
In a method for structuring the surface of a synthetic fiber, a substantially cylindrical fiber (2) is provided with a predefined surface structure (38, 38a, 38b) 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 μm and is then transferred into a rigid state while the created surface structure (38, 38a, 38b) is maintained.
Claims14
A method for structuring the surface of a synthetic fiber, wherein a substantially cylindrical fiber is provided with a predefined surface structure by means of plastic deformation, characterized by the following steps:
- a) supplying the fiber in a plastically deformable state;
- b) plastically deforming the fiber in an embossing process by means of at least one microlithographically structured embossing roller, which cooperates with at least one pressure roller, wherein each embossing roller and each pressure roller define therebetween an embossing zone for the fiber, and wherein each embossing roller has a maximum structural fineness of 10 μm;
- and
- c) transferring the fiber into a rigid state while maintaining the created surface structure.
