What is Polyimide Fiber(PI Fiber)

Polyimide Fiber (abbreviated PI) provides excellent mechanical properties, such as fire retardant, acid and alkali resistance, anti-oxidation, and are thermally stable up to approximately 350°C.
PI can be spun into yarn, dyed, and then made into a fabric by various methods including weaving, knitting, or felting.
The yellowish-brown PI gives it the gold-like color, and the anti-oxidation allows its color to remain the same after multiple times of use.

PI is the perfect material for garments that need protection against fire as it offers optimal protection to workers that need to perform in high-risk environments
Furthermore, PI Fiber-based fabrics are skin-friendly and highly color stable, can be used on livelihood fire retardant products such as fire blankets and furniture.
