Essentials

SaranTC fibers are made by blending pigment-containing thermochromic microcapsules into the same polymer that is used to make other Saran fibers, which are characterized by an outstanding capability for the development of bright, fresh, lasting hues and colors. The microcapsules become increasingly transparent under warming, resulting in a gradual change in the apparent color of the Saran TC fibers, throughout the color-transition temperature range.

Color change occurs.

When heated with a hair dryer, or cooled with chilled water.
In response to warm breath or body temperature.
In movement between differing indoor and outdoor temperatures.
And on many other occasions in everyday life and use.

Microcapsule blending enables.

Full development of bright, non-fading color.
Full retention of water and flame resistance.
Freedom from fiber-coating embrittlement.
