What GRS-certified recycled polyester is
Recycled polyester is polyester filament spun from reclaimed PET, mostly post-consumer drinks bottles and post-industrial polyester waste, that has been sorted, cleaned, melted and re-extruded into yarn; the yarn is then knitted or woven into the same fabric constructions as virgin polyester. In the trade it is sold as rPET, and in a finished football shirt or gym top it is not distinguishable from virgin polyester by look or hand.
GRS stands for the Global Recycled Standard, a voluntary international standard owned by Textile Exchange. It does two things a buyer cares about: it verifies that the recycled content claimed in a fabric is real, and it tracks that content through every processing stage, from the recycler to the spinner, the knitter, the dyer and the garment factory, so the claim on the finished garment can be traced back to its source.
ZipaSports in Sialkot, Pakistan, offers GRS-certified recycled polyester on request for any polyester-based garment in its range. It is not the default fabric; a buyer asks for it at enquiry and the fabric is sourced against that order.
What the GRS standard covers
The GRS covers more than the percentage of recycled fibre; it is a chain-of-custody standard with social, environmental and chemical requirements attached to every certified site. The table summarises what each part means for a sportswear buyer.
| GRS element | What it requires | What it means for your order |
|---|---|---|
| Recycled content | Verified recycled input, with a minimum share for certification and a higher share to carry the GRS label on a product | The recycled percentage on your hang tag is checked, not estimated |
| Chain of custody | Each site handling the material holds a scope certificate; each sale between sites is covered by a transaction certificate | Traceability from recycler to your finished garment |
| Social requirements | Worker rights and conditions at certified sites | Aligns with the BSCI audit already held by the factory |
| Environmental requirements | Management of water, energy, waste and emissions at certified sites | Supports a brand's environmental reporting |
| Chemical restrictions | Restricted substances in processing of the certified material | Complements OEKO-TEX Standard 100 fabric testing |
| Labelling | Rules on how the GRS mark and recycled claim may be shown | We follow the label wording rules on your tags |
Certificate copies for the recycled fabric used in an order are available on request; certificate numbers are not published on the website. Other certifications the factory holds are listed on the certifications page.
Recycled equivalents for every standard polyester fabric
A recycled polyester garment is run at exactly the same GSM, knit construction and finish as its standard equivalent; only the source of the polyester yarn changes. The table maps the standard fabric range to the recycled version ZipaSports can source on request.
| Standard fabric | GSM | Recycled equivalent | Garments |
|---|---|---|---|
| Polyester interlock | 140–180 | rPET interlock, moisture-wicking finish | Football, cricket, basketball jerseys |
| Polyester mesh / pin-dot mesh | 140–180 | rPET mesh | Ventilated jerseys, training tops |
| Polyester piqué | 160–200 | rPET piqué | Polo shirts, pit shirts, work polos |
| Interlock / microfibre | 140–180 | rPET interlock or microfibre | Team and training shorts |
| Polyester-spandex | 240–300 | rPET-spandex; the polyester share is recycled, the elastane is not | Leggings, compression, sports bras |
| Polyester-spandex rash guard knit | 180–220 | rPET-spandex, flatlock seams | BJJ, MMA and swim rash guards |
| Performance polyester fleece | 240–300 | rPET fleece | Training hoodies, tracksuits |
| Ventilated polyester mesh | 150–180 | rPET mesh | Motocross jerseys |
| 600D polyester | Woven, denier-rated | rPET 600D | Kit bags, backpacks, gym bags |
Cotton-polyester fleece at 280–350 GSM can use recycled polyester for its polyester share only; nylon-spandex, seamless nylon-elastane and cotton gi fabrics are not polyester and are outside the scope of this page. The full standard range is on the fabrics overview.
Sublimation and decoration on recycled polyester are identical
Sublimation printing works on recycled polyester exactly as it does on virgin polyester, because the dye bonds to the polyester polymer at roughly 200 °C and the polymer is the same whether it came from a bottle or from a new resin. Colour range, gradients, all-over coverage, printed names and numbers and wash-fastness are unchanged, and the print still cannot crack, peel or fade the way a surface print can.
The other decoration methods are also unchanged. Screen printing, multi-head embroidery, DTF transfer, heat transfer vinyl and tackle twill are applied to the finished fabric and do not depend on the yarn's origin. Woven neck labels, printed size tags and hang tags are attached in the same way, which is where the recycled claim itself is printed.
ZipaSports runs the same in-line and final QC on recycled fabric as on standard fabric: wash-fastness and colour-fastness checks on sublimated panels, measurement checks against the approved size specification and pre-shipment photos on request. The dye sublimation page covers the print process; the polyester interlock page covers the most common base knit.
Recycled versus virgin polyester: what changes and what does not
For a sportswear buyer the practical difference between recycled and virgin polyester is documentation and sourcing, not performance. The table is the comparison we give buyers who ask whether switching changes their product.
| Property | Virgin polyester | GRS recycled polyester |
|---|---|---|
| Fabric GSM and construction | Standard range | Same range, same knit |
| Sublimation printing | Full colour, all-over | Identical |
| Moisture-wicking finish | Applied at finishing | Applied the same way |
| Screen print, embroidery, DTF | Yes | Yes, no change |
| Availability at ZipaSports | Stock fabric | On request, sourced per order |
| Documentation | OEKO-TEX Standard 100 tested fabric | Plus GRS chain-of-custody certificate copies on request |
| Label claim | 100% polyester | Recycled content stated per the GRS label rules |
| Pricing | Quoted per enquiry | Quoted per enquiry; depends on fabric, quantity and decoration |
We do not claim that recycled polyester is softer, stronger or cooler than virgin polyester; run to the same specification it performs as the same fabric. Where a buyer wants to check for themselves, a physical sample in the recycled fabric takes 5–7 days, is charged at sample cost and is credited against the bulk order.
Who asks for recycled polyester
Recycled polyester is requested most often by brands and institutions that have made a recycled-content commitment in writing and now need a supplier who can document it. The buyer types below are the ones that typically ask for it.
- UK and EU sportswear and activewear brands with published recycled-content targets, or selling through retailers and marketplaces that ask for substantiation of environmental claims. Consumer-protection rules in the EU and UK increasingly require that a green claim on a product be evidenced, and the GRS transaction certificate is that evidence.
- Schools, colleges and universities whose procurement or sustainability policy asks for recycled content in PE kit, team kit and leavers' hoodies.
- Corporate buyers ordering work polos, company sports-day kit or event tees under a supplier sustainability policy.
- Event organisers and charities producing fun-run and tournament tees where the recycled claim is part of the event's messaging.
- Distributors and kit suppliers answering a tender that scores recycled content.
Buyers in these groups usually also need the export paperwork to line up with the claim, so the commercial invoice and packing list describe the fabric as recycled polyester. Regional pages for the UK and EuropeIrelandNew ZealandUAESaudi Arabia cover shipping and duties.

Frequently Asked Questions
Is recycled polyester good for sportswear?
Yes, recycled polyester is used for sportswear at the same GSM and construction as virgin polyester, so a 140–180 GSM rPET interlock jersey wicks, prints and washes the same as its standard equivalent. The difference is the yarn's source and the GRS documentation, not the performance of the garment.
Does sublimation work on recycled polyester?
Yes, sublimation works identically on recycled polyester, because the dye bonds to the polyester polymer at around 200 °C regardless of whether the polymer came from recycled bottles or new resin. All-over prints, gradients, names and numbers and wash-fastness are unchanged from virgin polyester.
What does GRS certified mean?
GRS certified means the recycled content in a fabric has been verified under the Global Recycled Standard, a Textile Exchange standard, and tracked through every processing site by scope and transaction certificates. It also imposes social, environmental and chemical requirements on certified sites, so the claim covers more than the fibre percentage.
What GSM is recycled polyester jersey fabric?
Recycled polyester jersey fabric is 140–180 GSM in interlock, mesh or pin-dot mesh, the same as the standard sublimation jersey range. Piqué polos are 160–200 GSM, performance fleece 240–300 GSM and polyester-spandex leggings 240–300 GSM, all matched to the standard equivalent.
Can I put the GRS logo on my garments?
The GRS mark can be used on a product only when the garment meets the standard's labelling rules, including its recycled-content threshold and approved wording, and the claim is backed by transaction certificates through the supply chain. ZipaSports prints the recycled claim on labels and hang tags in line with those rules and supplies certificate copies on request.
Is recycled polyester more expensive than standard polyester?
Pricing for recycled polyester depends on the fabric, the quantity and the decoration, and it is sourced per order rather than held as stock, so it is quoted with your enquiry rather than from a list. Contact ZipaSports on WhatsApp with the garment and quantity for a quote within 24 hours.
Which garments cannot be made in recycled polyester?
Garments whose main fabric is not polyester cannot be made in recycled polyester: nylon-spandex leggings, seamless nylon-elastane knits and cotton pearl-weave gis fall outside it. In polyester-spandex and cotton-polyester blends only the polyester share is recycled, and the elastane or cotton is standard.
What is the minimum order for recycled polyester garments?
The minimum order is 20–25 pieces per design, with lower quantities possible on request and no MOQ limit for sportswear brands, the same policy as standard fabric. Because the recycled fabric is sourced against the order, we confirm availability and any effect on the schedule in the quotation.
Can you provide GRS certificates for my order?
Yes, certificate copies covering the GRS recycled polyester used in your order are available on request, alongside the commercial invoice, packing list and certificate of origin for export. Certificate numbers are not published on the website; ask for the copies with your enquiry or at order confirmation.
