Method for producing a textile object having electrostatically charged fibres, and textile object

A method for producing a textile object having electrostatically charged fibres, comprising:

• spinning a first polymer to fibres of a first fibre type using a first die and at least one second polymer to fibres of a second fibre type using at least one second die, wherein the fibres are spun using a melt spinning process and/or using a solvent spinning process, or
• spinning a first polymer to fibres of a first fibre type and at least one second polymer to fibres of a second fibre type using at least one multipolymer die, wherein the fibres are spun using a melt spinning process and/or using a solvent spinning process,
• selecting the first polymer and the at least one second polymer such that the fibres produced from the first polymer can be so strongly charged triboelectrically by frictional interaction with the fibres produced from the at least one second polymer that a filter with a quality factor in excess of 0.2 can be manufactured with the textile object,
• shaping the textile object, wherein the frictional interaction occurs before and/or during shaping of the textile object, and/or
• inducing the frictional interaction during a finishing process,
• wherein, the first polymer and/or the at least one second polymer, contains at least one additive capable of binding free radicals and/or acting as internal slip agent.
