Abstract (en)

[origin: WO2008022993A2] The present invention relates to a process for producing polymer fibres, especially nano- and mesofibres, 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 fibres obtainable by this process.
