Heat-Activated Clothing

Steve,

I have no doubt this will find extensive application in undergarments of all types sold in certain shops.

And they thought the "mood ring" was cool?

How old is this technology?

AT LEAST 10 YEARS ++

Having worked at a UK dyer for over 15 years i well remember this product

Called Hypercolour in Uk sold by Global

Made by Matsui in Japan, with choice of temperature change

How is this different??

I wouldn't call this fabric heat-activated, it may confuse people with heat active which is a smart textile that really transfers heat to the body.

Long time ago, many companies had tried colorful concept. The market didn't accept it very well, like sun-change-color, luminescent fabric (fluorescence) and also the mentioned "heat-activated". There is a need for smart textiles and I thinks this is the preliminary concept of a practical garment that could help in our world.

I believe in carbon active fibers that vibrates at the same speed of human skin that when wearing cloths made of, will heat up your body by transferring that vibration to skin, as stated before. Although carbon fibers are not yet there due to particles are toxic and also stain almost anything.
