| titleOfInvention | Nonwoven filter fabric for bacterial-viral respiratory filters and method for its production (versions) |
| abstract | FIELD: textiles, paper. ^ SUBSTANCE: material comprises fibrous layers of a mixture of viscose, polypropylene and bicomponent fibers, bonded with the back-up substrate, in the following ratio of components: viscose fibers (0.17-0.33) tex - (20-40) wt.% polypropylene fibers (0.33-0.67) tex - (30-45) wt %, polypropylene fibers 1.7 tex - (5-10) wt.%, bicomponent fibers (0.22-0.40) tex (20 - 30) wt %, calcium chloride (15-50) wt %. The surface density of the obtained filter material is (100-500) g/m2, air permeability (550-850) dm3/m2s, hygroscopicity (25.0-47.5)%. The objects of the invention are also variants of the method of manufacturing non-woven filter material, the first of which involves the processing of viscose and polypropylene fibers with an aqueous solution of calcium chloride with the mass concentration (100-500) g/dm3 at processing module (1:21:5) of weight parts for viscose fibers, at processing module (1:1.51:3) of weight parts for polypropylene fibers. The version 2 of the claimed method provides for the processing of the whole filtering material with a solution of calcium chloride, which mass concentration is (100-500) g/dm3 at processing module (1:1.151:3) of weight parts. In both versions, drying of the treated material is carried out at a temperature not exceeding 80C and heat treatment with hot air at a temperature of (120-145)C. ^ EFFECT: obtaining a porous hydrophilic filter material with a high air permeability and stability of shape, providing moisture and warming of air entering the patient's lungs through a breathing filter when endotracheal anesthesia and mechanical lungs ventilation. ^ 18 cl, 1 dwg, 5 ex |
