The special samples for the test were prepared. They were built of fabric clothing fixed with the use of epoxy glue between two rigid rings made of epoxy-glass composite (Fig.6c).

3.2. Research assumptions

The tests conditions were as follows: - Cells temperature:

o Scenario 1 : 60°C o Scenario 2 :100°C o Scenario 3: 330 °C

- Distance between textile and Peltier cells was 5 mm for each scenario (Fig. 7a)); - Time of sample heating process – 5 minutes; - Measurement area on the sample was shown in Fig. 7b). The average temperature was taken from this area. The test steps were:: - heating the cell to a predetermined temperature, - stabilization of temperature on the Peltier cells, - placing the sample in measuring position and measurement.

4. Results

4.1. Fireproof textile – Proton

Test results has shown that the amount of heat radiation passed through the sample with TiSi coating was smaller than for the sample without coating. The example of that phenomenon was shown in Fig. 8.
