DiAPLEX - What's So Intelligent?
Micro-Brownian
Movement
The intelligence
of DiAPLEX lies in the unique way in which it takes advantage
of Micro-Brownian motion (thermal vibration). Micro-Brownian
motion occurs within the DiAPLEX membrane when the temperature
rises above a predetermined activation point. As a result of
this motion, micro-pores are created in the polymer membrane
which allow water vapor and body heat to escape. Because permeability
increases as the temperature rises, the membrane is able to respond
intelligently to changes in the wearer's environment and body
temperature.
Ambient Temperature
Response Function
DiAPLEX is also unique
in that the temperature at which Micro-Brownian motion begins
can be freely specified. This means that the activation point
can be set to match the environmental conditions in which a garment
is likely to be worn. For everything from heavy duty cold weather
gear to lightweight sportswear, DiAPLEX can provide an ideal
combination of thermal insulation and vapor permeability.
When ambient temperature is below activation point
Molecular structure is rigid, so permeability
is low and body heat is retained.
When ambient temperature is above activation point
Micro-Brownian movement creates gaps
between molecules, increasing permeability
so that moisture and body heat can escape.
Flexible Barrier Function
When the temperature
within a garment is low, the DiAPLEX membrane acts to reduce
permeability and prevent air and water molecules from passing
through it. This helps to retain body heat. As the temperature
inside the garment rises, however, the Micro-Brownian motion
increases membrane permeability causing water vapor to be expelled
to the outside air. This "flexible barrier function"
enables the garment to intelligently adjust its insulating properties
in response to temperature changes, assuring optimum comfort
in any environment.
