You've probably been asked by a buyer whether recycled swim fabric performs as well as virgin — usually right before they ask for the certification paperwork. Short answer: at the right spec, yes.
This page covers recycled swimwear fabric — RPET and recycled-nylon blends, what GRS certification actually proves, and where the trade-offs really sit.
What Recycled Swim Fabric Is Made From
Most recycled swim fabric starts as post-consumer PET — plastic bottles — spun into RPET polyester, then blended with elastane for stretch. Recycled-nylon versions exist too, usually from reclaimed fishing nets and industrial waste.
Does Recycled Cost You Performance?
This is the real question buyers care about. At the band we run, recycled polyester matches virgin on the numbers that matter for swim: chlorine resistance, four-way stretch, UPF and quick dry. The recycled-swim names you see at retail run 82/18 recycled polyester-elastane precisely because it holds UPF 50+ and chlorine resistance.
The honest trade-off is colour: recycled feedstock varies, so expect slightly more batch-to-batch colour fluctuation. We manage it with lab dips and strike-offs before bulk.
What GRS Certification Proves
The Global Recycled Standard verifies recycled content, chain-of-custody traceability, plus environmental and social criteria across the supply chain. For a brand making a recycled claim on a hangtag, GRS is the paper trail that survives an audit. We supply GRS-certified recycled swim fabric when your buyer needs it.
Recycled sits alongside the rest of the swim program — see the full picture in our swimwear fabric sourcing guide, the chlorine detail on our chlorine-resistant swimwear fabric page, and related sustainable options in our recycled sustainable fabric category.
Premium RPET & Elastane Blend
Our swimwear fabric is engineered with a precise blend of 82% recycled polyester (RPET) and 18% elastane, giving it a 4-way stretch that exceeds 25% elongation with >95% shape recovery. With a weight range of 180–240 GSM and a standard width of 150 cm, this fabric offers the ideal balance of coverage, compression, and comfort. The recycled polyester is sourced from post-consumer PET bottles, transforming plastic waste into high-performance swimwear material.

GRS-Certified Traceability and Integrity
Every roll of our swimwear fabric is independently audited and certified to the Global Recycled Standard (GRS). This ensures a verified recycled content of 20% to 100%, with full chain-of-custody documentation from post-consumer waste to finished fabric. Brands can confidently claim GRS certification with transparent tracking of every production step, supported by transaction certificates (TCs) and scope certificates (SCs).

Engineered for Performance and Durability
While traditional swimwear often relies on virgin nylon blends, our RPET fabric delivers superior performance with built-in UPF 50+ protection, blocking over 98% of UVA and UVB radiation. It also exhibits high chlorine resistance, preserving color and elasticity even after extended pool use. The moisture-wicking finish dries rapidly—contact time under 30 seconds—and the fabric maintains a colorfastness rating of Grade 4-5, resisting fading wash after wash. Compare this with UV Protection Stretch Fabric and Moisture Wicking Stretch Fabric for additional performance benchmarks.
Customization for Swimwear Collections
Available in customizable weights from 140 to 280 GSM and widths from 150 cm to 180 cm, this fabric adapts to diverse swimwear silhouettes—from sleek one-pieces to rash guards and bikinis. Fabric constructions include single jersey, interlock, and mesh, each offering different degrees of breathability and opacity. Customize your order further by consulting our Recycled Performance Fabric and Sustainable Activewear Fabric options.
A Sustainable Choice for the Circular Economy
By integrating recycled polyester with a GRS-certified supply chain, this fabric helps brands achieve sustainability goals. With up to 100% recycled content, each meter directly mitigates plastic pollution. The GRS certification also verifies responsible social and environmental practices throughout production. Opting for RPET swimwear fabric is a tangible step toward reducing the fashion industry's carbon footprint, without compromising on style or performance.
