Some peculiar electret properties of fibrous polymer materials have been studied by complementary methods. The residual polarization has been proved to result from capture of free charge carriers on two main types of defects, namely oxygen-containing groups and the defects formed from violated permolecular structure. A spontaneous electrel charge is generated in the fibrous material at both melt blowing and melt spinning and its value depends on the process parameters. The forced polarization of fibers in an external electric field makes the electret effect more pronounced and adds a specific character to the polarizing charge relaxation.
