FILTERING AND SORBING MATERIAL Russian patent published in 2009 - IPC B01D39/16 

FIELD: means of protection.

SUBSTANCE: invention relates to production of a filtering and sorbing material used in the means of personal respiratory protective equipment to cleanse the air form fumes and aerosols of hazardous substances. The filtering and sorbing material containing polypropylene fibers filled with microatomised carbon, fibers of sulfate unbleached cellulose and fibers of mercerised cellulose is obtained by adding the polypropylene fibers in the amount 5-10% of the total mass at the stage of grinding the sulfate unbleached cellulose after which combined grinding of the mixture is continued until the grinding degree of 28±2°SHR is reached, the mixture is then mixed with the fibers of mercerised cellulose and carbon, paper web is poured dried and treated with an impregnating solution containing nickel chloride (II) - 10%, ferrous chloride (III) - 10%, copper chloride (II) - 10%.

EFFECT: production of elestic well draped filtering and sorbing material with high mechanical and adsorbtion characteristics and a low aerodynamic resistance to respiration.
