PCM Thermo+

Comfort Zone:
Microclimate between the skin and the fabric that is perceived as most comfortable 28-30ºC (82°F – 86°F)
(R.A. Scott, Textiles for protection, 2005)
- Standard garment thermal insulation – Passive
- PCM thermal regulation - Active
Temperature variation in microclimate is determined by:
Body Heat
Change in environment
( The presence of PCM will buffer such fluctuations in temperature)
Thermoregulation & Perspiration
- If body temperature exceeds 37.5°C (98.6°F) the body needs to cool down
- Blood vessels under the skin dilate
- Body produces perspiration
- Cooling through evaporation
- PCM absorbs the heat from the body .
- Microclimate stays in the comfort zone for longer periods of time .
- Delays the onset of temperature rise to 37.5°C (98.6°F) .
- Less cooling needed for the body.
- Less perspiration.
- Cool sensation.
