Recycled Polyester vs Recycled Nylon: 6 Honest Facts

Recycled polyester vs recycled nylon is a common decision when specifying recycled synthetic fabrics.

Recycled polyester and recycled nylon are two of the most widely specified recycled synthetic fabrics in product manufacturing. Recycled polyester is typically made from post-consumer PET, such as used bottles, while recycled nylon is recovered from sources like discarded fishing nets and industrial waste. Both reduce reliance on virgin petrochemical inputs, but they differ in feel, performance and cost profile. Both are available through SUS Materials with swatches, sampling and certification details on request.

What is the difference between recycled polyester and recycled nylon?

The two materials come from different polymer families and behave accordingly. Recycled polyester is widely available, holds colour well and is a versatile workhorse for everything from linings to outerwear shells. Recycled nylon tends to be softer to the touch, more abrasion-resistant and more elastic, which makes it a common choice for performance wear, swimwear and bags that flex under load. Neither is universally superior; the right pick depends on the demands of the specific product. A useful first step is to map your functional requirements, abrasion, stretch, hand-feel, colour fastness, before choosing the polymer.

What does GRS certification actually verify?

The Global Recycled Standard (GRS) is a voluntary, full-supply-chain standard for tracking and verifying recycled content in a final product, and it also addresses chain-of-custody traceability, environmental and social criteria, chemical use and labeling.¹ Crucially, GRS verifies that recycled content has been independently audited rather than simply claimed. A product must contain at least 20% certified recycled material by weight to carry any GRS claim, and only products at 95% or above may be labeled as “100% recycled.”² Enforcement runs through third-party, on-site audits by certification bodies accredited under the standard.

Why certification matters for recycled fabrics

Recycled content is difficult for a buyer to confirm by eye, which is exactly why an audited standard like GRS carries weight. Without third-party verification, “recycled” is just a marketing word; with it, there is a documented chain of custody from input to finished roll. For brands, this matters both for regulatory compliance in markets that scrutinise environmental claims and for retailer requirements that increasingly ask for certification on file. The practical takeaway is to request the relevant certification documentation for the exact material and lot you intend to buy, rather than relying on a general category claim about a fabric type.

Performance trade-offs to weigh

Beyond the recycled story, the two fabrics carry the same broad trade-offs as their virgin counterparts. Polyester offers strong colour retention, dimensional stability and cost efficiency at scale. Nylon offers superior abrasion resistance and a softer hand, but typically sits at a higher price point and can be more sensitive to UV over time. Recycling does not change these fundamental polymer characteristics, so the choice between recycled polyester and recycled nylon should be driven by the end use first and the recycled narrative second. Sampling both against your real-world test protocol remains the most reliable way to decide.

How to specify recycled content correctly

When writing a spec, name the standard, the minimum recycled percentage and the documentation you require, rather than relying on the word “recycled” alone. Keep environmental language qualified, describing a material as lower-impact rather than making absolute claims you cannot substantiate. You can review both fabrics in detail on the recycled polyester and recycled nylon pages, and explore the wider range on the eco-textiles hub.

FAQ

Is recycled polyester as good as virgin polyester?
For most applications the performance is comparable, since the polymer chemistry is the same. Quality depends more on the processing and the specific lot than on the recycled origin itself.

Is recycled nylon more expensive than recycled polyester?
Recycled nylon generally sits at a higher cost level than recycled polyester, consistent with the difference between their virgin equivalents. The gap varies by construction and volume.

Does GRS prove a fabric is sustainable?
No. GRS verifies recycled content and chain of custody and sets environmental and social criteria; it is a credible signal but not a blanket claim that a product is “sustainable.” Always assess the full lifecycle.

What recycled percentage should I ask for?
That depends on your product and market. Specify a minimum certified percentage and request the documentation for the exact material you plan to order.

Choosing between recycled polyester vs recycled nylon

Lead with the product’s functional needs, then confirm recycled content with audited documentation rather than category claims.
