<p>A fibrous material, in particular a cellulose material, is subjected to heating and subsequent treatment at high pressure, in particular with application of an impregnation agent after the heating and before the high pressure treatment. High pressure treatment may be performed by means of rollers (12'). Heating and high pressure treatment render fibrous material more reactive with reactive impregnating agents. Material may be dry defibrated after impregnation. Impregnation agent is, in particular, metal oxide acylate or isocyanate. Resulting fibers are useful as reinforcing fibers in matrices and as absorbing fibers.</p> |
