CA 2694070

The invention relates to a high-strength and abrasion--resistant fibrous material and to a method for the production thereof. According to said method, a natural fibre material is solubilized in an alkaline manner. The fibrous material is treated with an alkaline material, without being subjected to mechanical stress a) at a temperature of between 5 and 30°C and then b) at a temperature of between 80 and 150°C, and is then optionally washed and/or dried.

L'invention concerne un matériau fibreux à rigidité élevée, résistant à l'abrasion, et un procédé de production de ce matériau par cuisson alcaline d'un matériau fibreux naturel, consistant à traiter le matérieau fibreux avec une substance alcaline sans le soumettre à une contrainte mécanique a) à une température de 5 à 30 °C, puis b) à une température de 80 à 150°C, ces étapes étant éventuellement suivies d'un lavage et/ou d'un séchage.
