The Third of a kind
• Human body – the most complicated thermo-regulating machine • Body’ heat release mechanism • Comfortable skin temperature • Autonomic regulation – Active movements
A phase change material (PCM) is a substance with a high heat of fusion which, melting and solidifying at a certain temperature, is capable of storing and releasing large amounts of energy. 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.
• Energy efficiency • Materials efficiency • Benign chemistry
•
The main challenge in developing textile PCM structure is the method of their use.
•
Encapsulation of PCMs in a polymeric shell is an evident selection, but it adds stiff weight to the active material.
•
Efficient encapsulation, core-to-wall ratio, out put of encapsulation, stability during application and incorporation of capsules onto fabric structure are some of the technological aspects being measured.
•
Though PCMs are being promoted in various types of apparel and connected products, the applications in which they can really work are limited.
•
As superior test methods are developed for PCMs, makers of PCM materials and garments will have to further cautiously target the markets in which their products do work well.
