摘要： The invention relates to a method for producing non-wovens, according to which a lyotropic solution of cellulose carbamate in N-methylmorpholine-N-oxide (NMMNO) is spun to several continuous threads into a precipitation bath via an air gap by extruding the same through a nozzle beam comprising several openings, whereupon said continuous threads are intermingled with the aid of gaseous medium and/or fluid that flows thereagainst. The invention further relates to such non-wovens and the use thereof.

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 method for producing non-wovens during which a cellulose carbamate solution is spun by means of extrusion through a nozzle block having a number of openings into a precipitation bath to form a number of endless threads and, afterwards, is mingled by subjecting it to a flow of a gaseous medium and/or fluid. The invention also concerns a non-woven of the aforementioned type and the use thereof.

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

摘要： The invention relates to a method of manufacturing tubular films from a solution of a mixture of cellulose and proteins by extrusion blowing the solution over an air gap into a precipitation bath, and to the films produced with this method and their application. Tubular cellulose films have been used for centuries as packaging material, particularly in the food industry and especially also as sausage skins. The particular advantages of the cellulose films are their good biodegradability, their high water absorption and the good water-vapour transmission. In addition to this, tubular films formed from proteins are also used for food packaging, preferably as sausage skins.

摘要： The invention pertains to a process for manufacturing cellulosic moldings wherein a solution containing cellulose dissolved in amine oxides is molded in a die and the molded solution is fed through an air zone into a regenerating medium. The molded solution is passed successively through at least two regenerating media, which are selected so that a slower coagulation takes place at least in the first regenerating medium than in the final regenerating medium.

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.
