Abstract:
A process for continuously coating a cellulose-based fibrous substrate web with a fatty acid chloride, comprising the steps of a) predrying a cellulose-based fibrous substrate web to an EN ISO 638:2008 dry matter content of less than 10%; b) coating the cellulose-based fibrous substrate web predried in step a) with a liquid fatty acid chloride composition at a DIN EN 20187 relative humidity of less than 20rh and a temperature below the boiling temperature of the liquid fatty acid chloride composition; c) thermally treating the coated cellulose-based fibrous substrate web obtained from step b).
