Is Nylon / Polyamide Vegan? Material Facts & Alternatives

Vegan status: Vegan

Also known as: Polyamide 6, Polyamide 6,6, PA6, PA66, Lycra Nylon

Origin

Synthetic — produced from petrochemical feedstocks (adipic acid and hexamethylenediamine for PA66; caprolactam for PA6).

Environmental impact

Rating: high. The production of nylon 6,6 releases nitrous oxide (N₂O), a greenhouse gas approximately 300 times more potent than CO₂. Also sheds microplastics. Not biodegradable. However, nylon is highly durable and long-lasting, which reduces per-use impact.

Durability

Excellent. Exceptionally strong, abrasion-resistant, and elastic. One of the most durable synthetic fibres.

Common uses

Tights/hosiery, swimwear, activewear, outdoor gear, bags, ropes, parachutes, toothbrush bristles.

Notes

Nylon was invented by DuPont in 1938 and was the first commercial synthetic fabric. It replaced silk in stockings during World War II. Econyl is a recycled nylon brand produced from discarded fishing nets, carpet waste, and fabric scraps — a significantly more sustainable option. Vegan but with high environmental footprint.
