Notes on Saran™ TC (Thermal Color Change Fiber)
1.Colorfastness to Light
Please avoid continual use in direct sunlight as colorfastness to light is low in some colors.
The softening point of Saran™ fibers is from 145 - 165℃ so they are not very heat-resistant.
When applying heat-set processing, settings at 120℃ or below, or at 110℃ if possible are recommended.
3.Use in Indicating Temperature Change
In areas with temperature change, there is a 10℃ range between the beginning and the ending of discoloration. There is also a 2 to 3℃ difference in discoloration temperatures depending on the colors, even in same-temperature types. Please do not use it as a precise temperature sensor.
Saran™ fibers can be stained with colorants such as disperse dyes and reactive dyes.
Fastness may be affected when dyed.
