FIELD: textile industry; may be used in manufacture of filtering nonwoven materials such as filter element of breathing apparatuses and respiratory units for cleaning air-gas mixtures from toxic aerosols. SUBSTANCE: nonwoven material consists of textile fibrous lap from anion-exchange modified polyamide fibers and a system of fastening loops of tricot bond from sewing thread and additionally includes the second system of fastening loops from yarn of hydrophilic modified polyamide fiber of charme bond. Sewing thread in the first system is used in the form of high-shrinkage thread. Hydrophilic thread content in material amounts to 10-15 mass%, and high-shrinkage thread, up to 8-12 mass.%. EFFECT: higher protective properties of material. |
