Is Nylon (Polyamide) Plastic-Free?
The honest chemistry, the performance trade-offs, and a straight verdict for founders deciding what their next line is actually made of.
Verdict: Not plastic-free, it is plasticNylon is plastic. It is a synthetic polyamide polymer made from petroleum, spun into fiber. It does not biodegrade and it sheds microplastics in the wash. Conventional nylon (PA6, PA66) is entirely petroleum-derived. The one meaningful distinction is bio-based polyamide made from castor oil, which is a genuinely different, plant-derived chemistry, and it is the polyamide platform OHZEHN-TEX is built on.
What is Nylon (Polyamide)?
Nylon is the common name for synthetic polyamide fibers, most often PA6 or PA66. Conventional nylon is polymerized from petroleum-derived monomers. It was the first fully synthetic fiber and remains a workhorse for its strength, abrasion resistance, and smooth hand.

How is Nylon (Polyamide) made?
Petroleum feedstock is converted to the polyamide monomers (caprolactam for PA6; adipic acid and hexamethylenediamine for PA66), polymerized, melted, and spun into filament. As with polyester, standard nylon has no plant content, so it is plastic.
How does Nylon (Polyamide) perform?
Very strong, highly abrasion-resistant, smooth, and elastic-feeling, with better durability and softer hand than polyester in many uses. That is why it shows up in swimwear, hosiery, and high-wear activewear. The environmental cost mirrors polyester: fossil feedstock, no biodegradation, and microplastic shedding.
So, is Nylon (Polyamide) plastic-free?
No, conventional nylon is not plastic-free; it is a petroleum plastic. The important nuance most glossaries miss: bio-based polyamide made from castor oil is a real, plant-derived polyamide chemistry with a very different feedstock. It is the difference between oil-based nylon and a plant-based polyamide, and it is central to how a plastic-free performance fabric is built.
Where you see it: Swimwear, hosiery, activewear, outerwear shells, and high-abrasion trims.
The OHZEHN-TEX™ take
This is the fiber where the OHZEHN-TEX story is sharpest. Instead of petroleum polyamide, OHZEHN-TEX™ is built on castor-oil-derived polyamide, a plant-based route to nylon's strength and hand without the crude-oil feedstock. Paired with corn-derived stretch, it targets the exact use cases nylon owns, on a 99.5 percent plant-derived platform.
Frequently asked questions
Is nylon plastic?
Yes. Nylon is a synthetic polyamide plastic made from petroleum. It does not biodegrade and it sheds microplastics. It is a different polymer family from polyester but it is equally plastic.
Is bio-based nylon plastic-free?
Bio-based polyamide from castor oil changes the feedstock from petroleum to a plant, which is a genuine and meaningful difference in origin and footprint. It is the plant-based route to polyamide performance. That plant-derived chemistry is the foundation OHZEHN-TEX is built on.
Nylon vs polyester, which is worse for plastic?
Both are plastic and both shed microplastics. Nylon is often more durable and softer; polyester is cheaper and dries faster. Neither is plastic-free. The alternative is a different, plant-based fiber, not choosing between two plastics.
