*5.3.3.3 Sample at wash temperature 60°C*

In **Figure 16** it can be observed that image A at magnification 1620X the mPCM around the fibre are brittle and fragmented and image B at magnification 3280X it is evident that the PCM capsule around the fibre is damaged, therefore the conclusion can be made that multiple laundering at higher wash temperatures are damaging to the PCM microcapsule, which causes the loss of thermoregulating content as identified in the TGA and DSC test results.
