FIELD: textile.
SUBSTANCE: proposed invention relates to textile industry, namely to production of non-woven materials, and can be used for creation of filter elements of gas and dust catching plants. Non-woven material consists of layers fixed by needling, one of which is formed from modified capron fibre, and second of hydrophilic capron fibre megalon, wherein layers are secured by needle-piercing on the side of layer of modified capron fibre of megalon with formation of continuous pile cover. Weight ratio of layers makes 1:0.2–0.6, height of nap makes 6–10 mm.
EFFECT: technical result is improved protective properties both on solid particles and on acid gases.
