Abstract

Abstract The layer of aerogel was applied to the surface of basalt fabric due to the possibility of improving a fabric protecting against the influence of hot environmental factors. The analysis of aerogel surface roughness and thickness of the obtained sample, resistance to contact heat for the contact temperature between 100°C and 250°C, and tests of resistance to the penetration of thermal radiation were carried out. In addition, thermal conductivity, thermal resistance, thermal diffusion, thermal absorption, and surface roughness were determined. The obtained results indicate the unevenness of aerogel application on the surface of basalt fabric. For this reason, work should be carried out on an appropriate technology that will allow them to be applied evenly on the surface of the fabric. The parameters tested and the results obtained are promising in terms of the possibility of using the fabric obtained in protective gloves.

Highlights

  • In the field of textiles, the use of aerogels has been noticed

  • The low thermal conductivity affects the limitations of heat loss, which is very important for materials with protective properties that guarantee the insulation against hot and cold environments

  • Measurements of thermal insulation properties were done on the fabric made of basalt fibers and fabrics made of basalt fibers with aerogel

Summary

Introduction

In the field of textiles, the use of aerogels has been noticed. So far, attempts have been made to exploit the hA. The low thermal conductivity affects the limitations of heat loss, which is very important for materials with protective properties that guarantee the insulation against hot and cold environments. Research regarding the application of aerogel to the surface of basalt fabric to improve the thermal properties of the fabric and the possibility of using it in protective gloves intended for the use in the hot environment was carried out. The Alambeta testing device was used to determine the thermal insulation properties of the basic and modified basalt fabrics [22] It was constructed and manufactured by the Czech company Sensora, and it is an automatic device used primarily to obtain dynamic and statistical evaluations of the thermophysical properties of textile materials [23].
