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.
