The invention relates to a method for producing a foldable textile fabric which has electrostatically charged fibers and to a foldable textile fabric. At least two separate nozzle bars are used, one bar being used to produce fine fibers and one bar being used to produce coarse fibers using a melt spinning method. At least the first nozzle bar, which is used to produce the coarse fibers, has concentric nozzles. The fine and coarse fibers are mixed at least in some regions during the process and are additionally electrostatically charged by means of a polar liquid. Filters with quality factors greater than 0.2 can be produced using the textile fabric. La invención se refiere a un método para producir un objeto textil plegable que tiene fibras cargadas electrostáticamente, y a un objeto textil plegable. Se utilizan al menos dos troqueles separados, uno para la producción de fibras más finas y otro para la producción de fibras más gruesas, al utilizar un proceso de hilado por fundición. Al menos el primer troquel, que se usa para producir las fibras más gruesas, tiene orificios concéntricos. Las fibras más finas y más gruesas se mezclan al menos en secciones durante el proceso y también se cargan electrostáticamente con la ayuda de un líquido polar. El objeto textil puede utilizarse para hacer filtros con un factor de calidad superior a 0.2.
