Abstract The paper discusses the methods of modification of melt-blown polymer materials by the addition of a bactericidal agent or superabsorbent directly to the fibre-forming area during the melt-blown production process. It also presents tests of textile composites designed for use in selected types of personal protective equipment worn in the workplace. One example of the application of textile composites is the protective footwear insole. The insole composites contain specially developed variants of melt-blown nonwovens made from PP, PC, and PA fibres. Microbiological, hygienic, and mechanical tests have shown that the optimum insoles for all-rubber protective footwear are those made of bioactive composites containing a PC melt-blown nonwoven. Another example of composite application is the air-purifying half mask. Filter composites contain polymer nonwovens with the addition of different quantities of a superabsorbent. They have been tested for particle penetration, airflow resistance, and moisture sorption.
