fibres with air, creating an ideal environment for evaporation. The PWAT material
absorbs heat when the wearer’s head is in contact with it. As there is an even distribution of water-absorbent polymer throughout the batting, the PWAT material provides
uniform cooling.
The SEM image of the breathable outer shell (top layer) of the PWAT material is
shown in Fig. 4.2. The above figure shows the top view of PWAT material, which is
a plain woven fabric.
