Abstract

See full text

A method for producing a pleatable textile object having electrostatically charged fibres, and to a pleatable textile object is described. At least two separate dies are used, one for the production of finer fibres and one for the production of coarser fibres, using a melt spinning process. At least the first die, which is used to produce the coarser fibres, has concentric orifices. The finer and coarser fibres are mixed at least in sections during the process and are also charged electrostatically with the aid of a polar liquid. The textile object can be used to make filters with a quality factor in excess of 0.2.
