FIELD: manufacturing technology.
SUBSTANCE: invention relates to electret fabrics. Electret fabrics contain a thermoplastic resin and an additive promoting accumulation of the charge. Additive promoting accumulation of the charge is a salt of substituted mercaptobenzimidazole containing a divalent metal. Electret fabrics can be represented by a nonwoven fibre cloth or a film. Electret fabrics are suitable for use as a filtering material.
EFFECT: development of an easily charged and efficient electret fabric.
