The heat-storage and thermo-regulated textiles and clothing are newer concepts they are two-way thermo-regulated new products, and have been studied for more than 30 years. The development history of heat-storage and thermo- regulated textiles and clothing is outlined in Table 3.1. 

Scientists have increasingly been studying the manufacture process and properties of heat-storage and thermo-regulated textiles and clothing for several decades. There will be more reports about basic, dynamic thermal resistance and its applications in the near future. 

Linear chain hydrocarbons are a non-toxic, inexpensive, extensive source of raw materials, suitable for varied usage. They are the most important PCMs in the manufacture of heat-storage and thermo-regulated textiles and clothing. 

Heat-storage and thermo-regulated textiles can be used as casual textiles, for example, face fabric, hner fabric, batting, etc. Thermal underwear, jackets, sports garments and skiwear have now come onto the market. 

Heat-storage and thermo-regulated textiles can absorb, store, redistribute and release heat to prevent drastic changes in the wearer s head, body, hands and feet. In the case of ski boots, the PCM absorbs the heat when the feet generate excess heat, and send the stored heat back to the cold spots if the feet get chilly. This keeps the feet comfortable. Ski boots, footwear and golf shoes are coming onto the market. 

PEG-treated fabric may be useful in medical and hygiene applications where both liquid transport and antibacterial properties are desirable, such as surgical gauze, nappies and incontinence products. Heat-storage and thermo-regulated textiles can keep the skin temperature within the comfort range, so they can be used as a bandage and for burn and heat/cool therapy. 

The manufacture, properties and applications of heat-storage and thermo-regulated textiles have been extensively studied since the 1980s but their future development is still not very clear. It is expected that similar importance will be attached to improving comfort to the wearer as was seen in the development of breathable membranes (Gore-Tex, Sympatex). These textiles were selected as one of the 21 inventions that will shape the 21st century by the editorial staff of Newsday. 

The experiment results show that a thermo-regulated textile that can regulate inner temperature effectively must have enough high thermal resistance. How to combine the heat-storage and release technology with the trapped-air technology is an area for future research. 

The group VI transition metal carbon compound can convert near infra-red rays into heat." " If the particles of ZrC are added to the heat-storage and thermo-regulated textile, they can absorb the near infra-red rays of the sun in daylight and convert them into heat that makes the PCMs in the textile change phase from solid to liquid. The textile releases its heat to keep its temperature relatively steady when the inner temperature is lower than the crystallizing point of the PCMs. ... 

Fibre type and heating rate appeared to have little effect on the overall heat content or thermal performance of the treated fabrics. The PEG-coated fabrics produced by the Mitsui Corporation were used as ski and sportswear. Other thermo-regulated textile products, such as blankets, sleeping bags, underwear, jackets, sports garments, socks, ski boots, helmets, etc., have come into the market since 1997. ...
