The goal of this study was to optimize and make comparative analysis of air-permeability of two types of nonwoven fabrics, plan and conduct two-factor experiments to determine the airpermeability of thermally bonded and needle-punched thermally bonded nonwoven fabrics, process experimental data, and determine the optimum values of target functions. Experimental and analytical methods were used in this work. Mathematical models describing the influence of proportional content of bicomponent fibers and thermal bonding pressure on air-permeability of the fabric were obtained. The properties of the nonwovens were optimized, the obtained data were compared, and recommendations are offered for making fabrics with the best performance properties.
