摘要

Utilization of the space warp knitted fabric and their combination with different non-textile materials increases in many areas of life nowadays. These materials are highly porous with excellent thermal properties. This paper presents an experimental investigation on the thermal behaviour and porosity of the sandwich structures defined for the production of protective rubber boots. The coefficient of the thermal conductivity was measured by the heat flow meter and togmeter. The porosity was detected by the using non-destructive method by the microtomography. The paper also describes the influence of porosity on the thermal conductivity of the sandwich structures defined for the production of protective boots. The results show significant effect of sandwich structure porosity on their thermal conductivity. Finally the paper describes the sandwich structures by the using special software for analysis the porosity of structures, their connectivity and the pores size distribution inside structures. The results of this study indicate that the sandwich structure containing 3D knit show better thermal properties.
