*5.3.1 Unwashed PCM: different areas at 500X magnification (100 μm)*

SEM images at magnification 500X was captured at 3 different areas on the sample to illustrate distribution of the PCM microcapsules within the sample. In **Figure 12** image A, B and C shows visible bulges on the fibres and in an uneven webbing that links the intercedes of micron sized PCMs. The bulges indicates that the PCM content is wrapped around the fibre and the micron sized PCM observed in the uneven webbing indicates the PCM content was incorporated through a pad-dry-cure process method.
