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.

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.
摘要翻译：本发明涉及一种用于生产直式陶瓷纤维的装置和方法。所述装置主要包括用于制备陶瓷粉末，氧化胺水溶液和纤维素的悬浮液的混合装置。悬浮液生产分批或连续进行，并且可以在一个或多个步骤中进行，同时加入全部或单独的组分。所述安装还包括用于浓缩所制备的陶瓷粉末，氧化胺水溶液和纤维素的悬浮液的装置，由此所述装置与加热，剪切和水蒸发分离并传输悬浮液，直到精确确定量的水蒸发，并将悬浮液在纤维素在氧化胺水溶液中的可成形溶液中形成陶瓷粉末。所述浓缩装置还包括与上述装置连接的装置，由此可模制的陶瓷纤维素溶液悬浮液被加工成绳状的陶瓷原纤维。所述浓缩装置允许形成直的陶瓷原纤维，并且可以与原料纤维束热解和烧结的装置集成。
