A procedure has been developed for predicting the protective effectiveness of hybrid fibrous filter materials (HFFMs) based on the Wheeler-Jonas dynamic adsorption model and available experimental data on the effect of relative humidity of the gas-air mixture on the adsorption capacity and the adsorption rate constant of activated carbon fiber materials (ACFMs) (for capturing C6H12) and impregnated fibrous chemisorbent-ampholytes with indication (IFCS-AI) (SO2/NH3). Based on the simulation results, such a sequence of arrangement and optimal layer thicknesses for IFCS-A, activated fibrous carbon materials (AFCM), and indicator layers in (HFFMs) were determined. Prototypes of HFFMs with standardized absorption capacity for SO2, NH3, and C6H12 were manufactured; and HFFM-BI, consisting of four layers – IFCS-A, AFCM, biocidal, and indicator. Specifications for the manufacture of a HFFM with standardized absorption capacity for toxic gases such as A, E, and K; process regulations for the manufacture of the trifunctional nonwoven hybrid fibrous filter material HFFM-1 and process regulations for the HFFM with a absorption capacity response indicator for acidic/basic gases; an anatomically adapted design of the face part of a respirator half-mask, taking into account the individual anthropometric parameters of users of different ages have been developed. A new design of a filtering respirator with an improved obturation strip shape has been developed, taking into account the anthropometry of the user’s face.
