Comparative analysis of protective garments system with fleece and spacer based removable inserts

The measurement results for the thermal insulation of the outer shell, removable thermal inserts, and protective garments system (PGS), as well as a comparative analysis of the thermal insulation, are presented. Both protective garments systems are made from the same materials. One removable thermal insert is made of fleece, while the other is made of spacer material. Tests of the thermal properties of the protective garments system were conducted using a thermal manikin. These studies have shown that the primary contributors to thermal insulation are the removable thermal inserts, while the outer shell, made of laminate, serves a protective function against wind and moisture. From the measured thermal insulation values and established results, it is evident that the outer shells of both protective garments systems have values slightly greater than 1 Clo, while the removable thermal inserts in the protective garments system have significantly higher thermal insulation values of 1.45 and 1.78 Clo. Thus, the total thermal insulation increases to about 2.3 Clo, indicating that removable thermal inserts can more than double the thermal insulation of the protective garments system.
