<p>Cellulose carbamate-spinning solution comprises a solution of cellulose carbamate in at least one ionic liquid, where the cellulose carbamate concentration, in the spinning solution, is at least 15 wt.% and has a zero-shear viscosity, measured at 100[deg] C, of 50-7500 Pas. Independent claims are included for: (1) a method for preparing a cellulose carbamate-non-woven fabric comprising extruding the spinning solution in a melt blown process through a nozzle block with at least 20 nozzle holes, stretching the fibers, from the nozzle block, through a temperature-controlled air flow, and coagulating by spraying with a coagulating liquid and subsequently either the fiber is formed as continuous filament and formed into a matting, or the fiber is formed with finite length and is formed into the matting; and (2) cellulose carbamate-non-woven fabric obtained by the above method.</p> |
