FIELD: textiles, paper.
SUBSTANCE: proposed electret linen which contain a mixture of thermoplastic resin and additives to create a charge. Additives to create a charge include trianilinetriazine materials substituted by ester and substituted by amide. The linen made from mixtures may take the form of films or fabrics of woven fibrous material. The linen of woven microfibre material is suitable for use as a filtering medium. The invention provides a electret linen which can easily be charged using different charging mechanisms, such as corona charge excited by direct current, hydrocharge or a combination thereof.
EFFECT: electret linen has the ability for relative long-lasting charge retention.
