Abstract:
A process for the preparation of lyocell fibre or film by extruding a solution of cellulose in amine oxide through a spinneret or film die at elevated temperature via an air gap into an aqueous precipitation bath, thereby to form said fibre or film, characterised in that 0.1 to 60 wt % based on cellulose of a thermoplastic low-melting polymer is incorporated into the cellulose solution, the low-melting polymer having a melting point above 25.degree. C. but below the extrusion temperature of the cellulose solution, whereby said low-melting polymer is in a melted state during said extrusion step and is aligned in the axial direction of said fibre or film as said solution is extruded.
