Abstract

The invention relates to a process for the production of saturated fiber structures. The process includes (a) introduction of a fiber structure onto a conveyor belt; (b) application of a solution including monomer and optionally including activator, and optionally including catalyst in at least one line to the fiber structure; (c) passage of the fiber structure with the solution through at least one roll pair in which pressure is exerted on the fiber structure; and (d) cooling of the saturated fiber structure, so that the monomer solidifies.
