Patent

CA 2153981

The invention concerns dispersion of the cellulose based fibres in straw by the aid of alkali and strong mechanical agitation. This solubilizes the pentosane in the straw, and turns the mixture into a high viscosity paste, so that the forces from the agitation tear the individual straws apart and also disperse the fibres. In that way the fibres may be dispersed at solid content up to 85 % against only 8 % by traditional methods. The treatment results in a moulding paste, and this may be used directly for plastic forming of cellulose based fiber products after neutralising.
