abstract |
The present invention relates to a process for producing polymer fibers, especially nano- and mesofibers, by the electrospinning process, in which a colloidal dispersion of at least one essentially water-insoluble polymer and of at least one nonionic surfactant, if appropriate further comprising at least one water-soluble polymer, is electrospun in an aqueous medium. The present invention further relates to fibers obtainable by this process. |
