Nylon Fibre: Market Size & Forecast 2026

The global nylon fibre market sits at approximately USD 34.2 billion in 2025 (base year), structurally anchored by a feedstock cost stack in which caprolactam and adipic acid account for roughly 62% of finished conversion cost. Nylon 6 (PA6) commands 58% of grade volume against 35% for Nylon 66 (PA66), with the latter persistently trading at a 15-20% price premium that reflects the dicarboxylic/diamine monomer complexity. Demand growth runs at 5.8% CAGR through 2032, held in a balanced-to-softening supply posture as new Asian Nylon 6 capacity comes online against a backdrop of automotive lightweighting and industrial-yarn demand that absorbs roughly 50% of total production. > **Analyst Take.** The call is to move to caprolactam-indexed contracts before Q3 2026, not because caprolactam is rising, but because it is not rising fast enough to hold supplier margins.
