The invention relates to a method for preparing a yarn, in particular a multifilament yarn, for use as a textile reinforcement in a matrix material, in particular a mineral matrix material, a textile reinforcement and a component comprising this reinforcement. The object of the invention is to improve the wettability of multifilament yarns, especially for aqueous mineral coatings. To solve this, the surface of the yarn is modified by means of a plasma-chemical and / or plasma-physical process in such a way that the resulting modification at least improves the wettability.
