Abstract
A method is provided for coating a fibrous web, in particular a fibrous web comprising nanocellulose fibres. The method includes steps of applying a coating agent to a textured surface region of a textured substrate, applying a fibre furnish or a wet fibrous web onto the coated textured surface region of the textured substrate, optionally dewatering to provide a wet fibrous web, and drying said wet fibrous web such that at least a portion of said coating agent is transferred to said fibrous web. The method provides a coated fibrous web with improved barrier properties.
