Introduction:-

What is PCMs??PCM – Phase Change Materials

How PCM works in Textiles??

Principle of Phase Change Material:

Principle of Phase Change Material:

Types of PCMs

Phase Change Materials:

PCMs DefinationHeat 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

Construction of PCMs

How to Incorporate PCMs In Textiles????

Filling or impregnatingFibre SpinningCoatings during FinishingFoam dispersion

PCM & Clothing Comfort

Testing of PCMs Incorporated Textiles

Testing of PCMs under Microscope

Scanning electron micrograph of typical MPCM in water carrier fluid

Properties of PCM Incorporated textiles

Desirable QualitiesChemical stableNon corrosive and non toxicLong lastingCommercial availabilityLow cost Reliability

Other ConsiderationsToxicity: 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

Challenges & Opportunities

LimitationsCostlyCoating reduces the air

permeability and moisture transmission etc.

Only perform for short intervals Does not absorb all the heat Reduces the dimensional stability
