    摘要: The invention relates to a method for the production of cellulose carbamate by reactive extrusion and for the production of moulded articles made of regenerated cellulose. The method for the production of cellulose carbamate is based thereby on the activation of cellulose, subsequent separation of the activation solution and following thereon reactive extrusion of the activated cellulose. Typical examples of moulded articles which can be produced therefrom are fibres, films, beads, sponges or sponge-type cloths.

    摘要: The invention relates to a process for producing flexible cellulose fibres by spinning solutions of the cellulose through spinnerets over an air layer in an amine oxide-containing aqueous and/or alcoholic regenerating bath followed by drying, in which the damp threads from the spinneret are taken before drying through at least one post-treatment bath containing water and water-miscible alkanols, diols, triols or mixtures thereof, and a washing bath containing water, an alkanol, a diol or a triol.

    摘要: The invention concerns a profiled part and aggregates for making same. The aggregates contain a material for plastic matrix technique and an adherence promoter. Regenerated cellulose fiber elements are incorporated in the matrix material. The characteristic profile of a profiled part made from such aggregates corresponds substantially to that of profiled PC/ABS parts, the profiled part of the invention being, however, capable of being produced at a more advantageous cost, being more recyclable and being, moreover, capable of being shaped at lower temperatures.
