Abstract:

Conveyor belts are widely used in almost all fields of industry, agriculture and architecture. They are also used in mines of raw materials and minerals, in the cement and lime industry, in paper and sugar mills, as well as in agriculture, power and etc. Conveyor belts consist of a woven fabric carcass and rubber covers. In the production process, polyamide polyester vulcanised fabrics are subjected to high temperatures. The aim of the study was to examine how the process of heat treatment affects the internal geometry of synthetic fabrics and what the impact of the weave on these changes is. An experiment was performed by subjecting nine samples of polyester and polyamide fabrics of different weave to heat treatment at 160 °C for 5, 10 and 15 minutes. The scheduled study was to mirror the conditions prevailing in the vulcanisation. Analysis of the measurements of the basic parameters characterising the internal structure of fabric shows that the weave affects the size of their changes during exposure to high temperatures.
