1. FR Fabric - Inner layer:
The flameproof textile structure was developed by combining FR hydrophobic Polyester fibres (in contact with the body to avoid wet feeling) with FR hydrophilic aramide fibres, which create an active suction channels that transport the moisture away from the skin.

2. Polymer effect (Hydrogel particles inside PU melt matrix):
The polymer coating will absorb and bind the excess of moisture migrating through the FR cotton fabric if the temperature is maintained below the threshold.
In case temperature increases, the coating will release the sweat accumulated, reproducing the human natural sweating process through evaporative cooling.

3. FR Cotton fabric:
To avoid the scattering of the swollen Hydrogel particles out of the FR plain fabric and to allow the migrating of water vapour out of the fabric, a FR cotton fabric was quilted to the coated FR plain fabric. The outer fabric is composed by a Cotton fabric (weight 90 g/m2) treated with the product “Antifiamma L” by A.CHI.MO (concentration 190 g/l) using the foulard technique at Foltex. The result is a FR Cotton fabric suitable to be quilted on the coated with hydrogel surface of the FR plain fabric. This multilayer structure, mimics physical mechanisms for human body thermoregulation.
