摘要： The invention relates to an installation and method for producing straight ceramic fibres. Said installation essentially comprises a mixing device for producing a suspension of ceramic powder, aqueous amine oxide and cellulose. The suspension production occurs batch-wise or continuously and can take place in one or several steps with the addition of all or individual components. Said installation also comprises a device for concentrating the produced suspension of ceramic powder, aqueous amine oxide and cellulose, whereby said device intensively mixes with heating, shears and transports the suspension with water evaporation, until a precisely determined amount of water evaporates and a suspension of ceramic powder is formed in a mouldable solution of the cellulose in aqueous amine oxide. Said concentrating device also comprises a device linked to the above mentioned device, whereby the mouldable ceramic cellulose solution suspension is processed into ceramic raw fibres in a rope shape. Said concentrating device permits straight ceramic raw fibres to be formed and can be integrated with an installation, in which the raw fibre bundles are pyrolyzed and sintered.

摘要： The invention relates to a method for producing shaped bodies, especially threads or foils, from at least one polymer of the groups consisting of polysaccharide, polysaccharide derivative or polyvinyl alcohol by forming a solution of the polymer that contains an additive in a solvent containing amine-N-oxide, extruding the solution and precipitating the extrudate by contacting with a coagulant. The invention is characterized in that at least two polymeric solutions are formed. At least one of the two polymeric solutions contains one or more finely distributed additives and the at least two polymeric solutions are simultaneously extruded forming a combined extrudate.
