This invention relates to a method for producing proteinaceous shaped articles from globular proteins according to the NMMO method, and to proteinaceous shaped articles themselves that are made from globular proteins according to the NMMO method. According to the invention, a suspension consisting of aqueous NMMO and of these precrosslinked proteins is transferred into a spinning solution, whereby the suspension contains a polysaccharide and/or a polysaccharide is added to the extrusion solution. The spinning solution is extruded into a precipitation bath through a form tool and through an air gap. Afterwards, the shaped article is washed with an aqueous liquid without the use of solvents and is subsequently hardened using known crosslinking reactions. The produced solutions are processed for a diverse product-oriented processing, preferably on the basis of known wet and dry/wet spinning techniques, optionally in conjunction with multi-constituent spinning techniques. The produced solutions can be processed using spin casting or other shaping techniques in order to produce, by these means, e.g. monofil and polyfil filaments, staple fibers, microfibers, nonwovens, foils, membranes, coatings, films or other shaped articles.
本发明涉及一种根据NMMO方法用球状蛋白质生产蛋白状物品的方法,以及根据NMMO方法用球状蛋白质制成的蛋白状物品本身。根据本发明,将由水性 NMMO 和这些预交联蛋白质组成的悬浮液转移到纺丝溶液中,悬浮液中含有多糖和/或在挤出溶液中加入多糖。纺丝溶液通过成型工具和气隙挤入沉淀槽。之后,在不使用溶剂的情况下,用水性液体清洗成型物品,然后使用已知的交联反应硬化。生产出的溶液可进行多种产品加工,最好采用已知的湿法和干法/湿法纺丝技术,也可选择结合多成分纺丝技术。生产出的溶液可以使用纺丝铸造或其他成型技术进行加工,以便通过这些方法生产单纤维和聚纤维长丝、短纤维、超细纤维、无纺布、箔、膜、涂层、薄膜或其他成型物品。
