No. 814: Fiber made of carbon nanotube is developed by Kuraray's subsidiary (November 29, 2013)

Kurarayliving, one of the subsidiaries of Kuraray, developed fiber made of carbon nanotube. Because carbon nanotube has 10 times higher heat conductivity than copper, it can increase the temperature of a 70 cm-square cloth instantly using 100 volt electricity. In addition, the new fiber decreases power consumption by more than 20%. In the initial stage, the company plan to apply it to heating appliances like electric carpet as well as to snow melting equipment.

Polyester fiber is emerged in a liquid in which molecules of carbon nanotube are dispersed evenly for coating. In the past, it was rather hard to put in molecules in the same density when powder carbon nanotube is dissolved in a liquid, but Kurarayliving developed a special solvent that allows molecules to line in the same density for the first time in the world. The company plans to market the new fiber to electric appliance manufacturers starting December. It will be sold for 10,000 yen per square meter, and mass production is expected to halve the price in the future.
