FMI expects the bio-based flame retardant cellulosic apparel market to shift toward a qualification-led growth model, where regulatory durability and scale outweigh sustainability positioning. As procurement standards tighten, demand will concentrate around integrated suppliers offering inherently flame-retardant fibers with wash-durable, non-leaching performance. This shift is likely to accelerate consolidation and marginalize finish-dependent and non-integrated producers over the forecast period.
