Nonwoven material |
| abstract |
FIELD: manufacture of nonwoven sorption-filtering materials. SUBSTANCE: nonwoven material has two layers fixed together by needle stitching. One layer is made from modified capron fiber megalon and other layer is made from mixture of anion-exchange fiber based on grafted copolymer of polycaproamide and polydiethylamine ethylacrylate and cation-exchange fiber based on phosphorylatedgrafted copolymer of polycaproamide and polygilicidylmethacrylate, with content of the latter in mixture being 30-70 wt.%. Weight ratio of layers is (0.2-0.4):1. EFFECT: increased efficiency and improved protective properties as to aerosol salts. 1 tbl |
