The present invention provides a process for producing low fibrillating cellulose fibers by a dry-jet-wet spinning process wherein cellulose is treated with a solvent containing imidazolium ionic salt in a spinneret maintained at a temperature of 100-120&#xb0; C. and the spun fibers drawn to the coagulation bath containing ionic salt with the draw ratio less than 5, to produce fibers with fibrillating index less than or equal to 3.

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 &#x3c3; of the coagulant or the mixture of coagulants is 99% to 30% of the surface tension &#x3c3; of water, the surface tension being measured according to ASTM D 1590-60 at a temperature of 50&#xb0; 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.

The present invention relates to a method for preparing L-menthol in solid form, specifically in the form of flakes, by bringing an L-menthol melt into contact with two chilled surfaces distanced from one another. Moreover, the present invention relates to the L-menthol in solid form obtainable by said method, and also to its use for incorporation into utility and consumer goods of all kinds.
