摘要： A solvent system for biopolymers in the form of carbohydrates which is based on a molten ionic liquid, with additives being present in the solvent system if appropriate, is described. This solvent system comprises a protic solvent or a mixture of a plurality of protic solvents, and if the protic solvent is water alone, this is present in the solvent system in an amount of more than about 5% by weight. Carbohydrates can be incorporated into the solvent system, in particular in the form of starch, cellulose and derivatives thereof, and the solvent system can then be employed for regenerating the carbohydrates dissolved therein. In addition, a particularly advantageous method of producing the solvent system containing the carbohydrates and for producing regenerated carbohydrates, in particular in the form of regenerated cellulose fibres, is described. The invention accordingly also provides such spinning fibres which are nonfibrillating. The invention offers, in particular, economic advantages over the systems of the prior art.

摘要： The invention relates to a method for producing regenerated biopolymers in the form of carbohydrates, using a solvent system that contains the biopolymers dissolved therein. The solvent system is based on a melted ionic liquid and optionally a protic solvent or a mixture thereof. The biopolymers dissolved in the solvent system are precipitated in a coagulation medium, said medium comprising a protic coagulant or a mixture of protic coagulants. The method according to the invention is characterized in that the surface tension σ of the coagulant or the mixture of coagulants is 99% to 30% of the surface tension σ of water, the surface tension being measured according to ASTM D 1590-60 at a temperature of 50°C. The method according to the invention is economical and flexible and leads to advantageous products, especially in the form of staple fibers which are especially not fibrillated and have an advantageous wet to dry strength ratio.
