2. Introduction:-

3. What is PCMs??
PCM – Phase Change Materials

4. How PCM works in Textiles??

5. Principle of Phase Change
Material:

6. Principle of Phase Change
Material:

7. Types of PCMs

8. Phase Change Materials:

9. PCMs Defination
Heat of Fusion [kJ/kg]:
Amount of energy required to melt
one kg.
Duration Index [J/(cm3*oC)]:
Comparison of how long a PCM will
remain at a constant temperature
during the phase change.
Calculated as: D.I. = hf ρ / ΔT

10. Construction of PCMs

11. How to Incorporate PCMs In
Textiles????
Filling or impregnating
Fibre Spinning
Coatings during Finishing
Foam dispersion

12. PCM & Clothing Comfort

13. Testing of PCMs Incorporated
Textiles

14. Testing of PCMs under
Microscope
Scanning electron micrograph of typical MPCM in water carrier
fluid

15. Properties of PCM Incorporated
textiles

16. Desirable Qualities
Chemical stable
Non corrosive and non toxic
Long lasting
Commercial availability
Low cost
Reliability

17. Other Considerations
Toxicity: n-Undecane, TEA-16,
n-Dodecane are all hazardous
materials.
Compatibility: Above all the chemicals
are corrossive in naure.
Cost: n-Undecane - $ 250/ltr
TEA-16 - $ 8/Kg
n-Dodecane - $ 116/ltr

18. Applications
Space
Sports Wear
Bedding & Accessories
Medical Applications
Shoes & Accessories
Casuals
Home Textiles
Others

22. Market For PCMs

23. Challenges & Opportunities

24. Limitations
Costly
Coating reduces the air permeability
and moisture transmission etc.
Only perform for short intervals
Does not absorb all the heat
Reduces the dimensional stability
