What is phase change material in textile?
Phase change materials (PCM) take advantage of latent heat that can be stored or released from a material over a narrow temperature range. PCM possesses the ability to change their state with a certain temperature range. This is followed by an account of incorporation of PCM in the textile structure are summarized.
What is Thermocule PCM?
Outlast® technology, originally developed for NASA, utilizes phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort. These Thermocules™ can be incorporated into fabrics and fibers and have the capacity to absorb, store and release excess heat. …
Why does increasing the temperature cause a substance to change in succession from a solid to a liquid to a gas explain?
Increasing temperatures cause the molecule in the substance to gain kinetic energy and begin to vibrate and move at high momentum. More heating gives the molecules more kinetic energy and enables the molecule to further move away from each other and transform to gas.
How do you select a phase change material?
There are several factors that need to be considered when selecting a phase change material. An ideal PCM will have high heat of fusion, high thermal conductivity, high specific heat and density, long term reliability during repeated cycling, and dependable freezing behavior.
What kind of material is a phase change material?
Phase Change Material. Phase change materials (PCMs) are substances which absorb or release large amounts of so-called ‘latent’ heat when they go through a change in their physical state, i.e. from solid to liquid and vice versa.
Which is thermo regulated clothing with phase change materials?

What happens when a material changes from solid to liquid?
Heat is absorbed or released when the material changes from solid to liquid and vice versa; thus, PCMs are classified as latent heat storage (LHS) units. There are many different types of phase change material, usually capable of changing between a minimum of two physical states.
What is the purpose of liquid vapour phase change?
Liquid–vapour phase change is a useful and efficient process to transfer energy in nature, as well as in numerous domestic and industrial applications.
