The process of individualizing personal protective equipment (PPE) is aimed at achievingoptimal fit to the user’s body, thus maximizing comfort, especially when PPE is applied in critical conditions. The aim of the research was to confirm the possibility of implementing PPE in rea industrial conditions and to estimate the comfort of use in real conditions of use. In order to perform the last stage of the personalization procedure for firefighter suits, process qualification was carried out in an industrial environment, and the firefighter’s PPE fabricated was validated under real conditions of firefighters’ activities. The effect of implementation of the individualization procedure confirmed optimal fitting of the PPE to the individual user’s body and allowed for improvement of the comfort of use.

The functionalisation of textile products and materials using the low temperature plasma technique is increasingly used in industrial practice, mainly because of the many benefits, often unattainable with the use of other techniques. The study focused on the modification of the composite textile materials - sheets of Ultra High Molecular Weight Polyethylene (UHMWPE) fibres (Dyneema ® SB51) by applying the surface deposition of silicone-like polymer in an environment of low temperature plasma. The aim of this study was to evaluate changes in the mechanical and physical properties of modified ballistic textiles un der simulated storage conditions in accelerated time. Based on experiences in planning the research on accelerated aging, a test programme was developed for the assessment of changes during the aging process in ballistic fibrous materials under various environmen tal conditions. The process of low temperature plasma modification affected the mechani cal properties of the ballistic composite textile materials during the accelerated ageing using temperature or temperature and humidity. The effect of the modification varied with the mechanical properties investigated.
