LOI (Limiting Oxygen Index) is perhaps the most critical specification for flame-retardant applications. LOI represents the minimum oxygen concentration required to support combustion. Since normal air contains approximately 21% oxygen, a fiber with LOI of 26% or higher will self-extinguish in normal atmospheric conditions ^[4]. Premium grades like Kaneka's Protex achieve LOI values of 32-34%, making them suitable for high-risk environments such as military uniforms, firefighter gear, and industrial protective clothing.

Denier per Filament (dpf) affects both the hand feel and end-use performance. The industry standard offers two primary options: 3.0 dpf for standard applications and 1.5 dpf for self-extinguishing and expanding char variants ^[3]. Lower denier fibers provide softer texture and better drape, making them ideal for wig and hair extension applications (which account for over 54% of market demand). Higher denier options offer greater tensile strength and abrasion resistance, preferred for industrial fabrics and protective apparel.
