Medical textiles represent one of the fields of technical textiles. They are fiber products and structures intended for first aid or clinical treatment of wounds and/or treatment of diseases and must therefore meet requirements such as non-toxicity, non-carcinogenicity, non-allergenicity, antimicrobiality, biodegradability and biocompatibility. They are classified into textiles for implants, medical textiles for outdoor use, medical textiles for health maintenance, textiles for hygiene products and textiles in prostheses. As part of the thesis, we compared eight different nonwovens used for medical textiles to maintain health, as a fulter layer in medical masks. The nonwovens discussed in the work are multilayer textiles that differ according to the process of making the base layer. The considered samples are made by a combination of spunbonding, meltblowning and combinationsof both procedures. They differ in the number of layers, combinations of web formation processes, thickness, fiber diameter and raw material composition. In the experimental part, we determined the breaking force and breaking elongation, air permeability, water vapor permeability, porosity and thermal conductivity. Based on the results obtained in the thesis we can conclude that samples 3, 4 and 5 have optimal air permeability; to filter harmful substances well when passing through a mask for protection, water vapor permeability and thermal conductivity and are most suitable for use as multilayer nonwoven textiles used for medical masks.
