Microcapsules loaded with phase change materials (PCMs) have been incorporated into various textiles (83). They provide enhanced heat capacity not easily achieved in other ways. Nelson (84) discusses a variety of textile applications of microcapsules including encapsulated PCMs. Encapsulated PCMs offer much promise as a means of improving the thermal capacity of various heat-transfer fluids (85). 

Gateway Technologies has reported the application of heneicosane, eicosane, nonadecane, octadecane, and heptadecane as phase change materials for insulative fabrics. This material can be 425% as warm as a high bulk wadding. Schoeller Textil AG Switzerland has also explored the application of micro-encapsulated phase change materials like waxes, which offer interactive insulation for skiwear, snowboarding and ski boats. They store surplus heat and the wax liquefies when temperatures drop, the microcapsules release the stored heat. 

Incorporating microcapsules of PCM into textile structures improves the thermal performance of the textiles. Phase change materials store energy when they change from solid to liquid and dissipate it when they... 

There are many thermal benefits of treating textile structures with PCM microcapsules such as cooling, insulation and thermo regulating effect. Without phase change materials the thermal insulation capacity of clothing depends on the thickness and the density of the fabric (passive insulation). The application of PCM to a garment provides an active thermal...
