Cellulose multi-component fibers from ionic liquids

A process for the concerted dissolution of cellulose and polyacrylonitrile in ionic liquids is discussed. Besides the preparation of these polymer solutions, the shaping by means of dry-wet-processes making cellulose-PAN-fibers is described. Furthermore, the textile-physical properties and the water retention behavior, the fibrillation tendency and the dyeing properties of the fibers resulting from this process are discussed. The results show that a new kind of fibers is available with specific, adjustable properties. These properties depend on the type of the polymers and the solvent used. A special role is played by the ratio of the polymers.
