Abstract (en)
[origin: DE102006050279A1] Production of polymer fibers (A) involves electro-spinning of an aqueous solution containing oppositely charged polyelectrolytes (I). Independent claims are included for: (1) the fibers (A) obtained by the process, specifically having a diameter of 10 nm bis 0.01-50 (especially 0.1-1) mu m and a length of at least 50 mu m; (2) an aqueous solution containing oppositely charged (I), plus at least 0.5 wt. % (based on the overall solution) of a water-soluble polymer (II) of water solubility at least 0.1 wt. % and at least one nonionic surfactant (III); and (3) the use of (III) in the production of polyelectrolyte complex fibers by electrospinning.
