“rPET fabric” is a useful description, but it is not enough for responsible sourcing. Buyers should verify recycled content, certification scope, supply chain documentation and whether the final fabric performance still fits the garment.
Certification may be relevant, but buyers should read what the certificate covers. A yarn certificate, fabric transaction certificate and finished product claim do not mean the same thing.

A recycled claim needs support
“rPET fabric” is a useful description, but it is not enough for responsible sourcing. Buyers should verify recycled content, certification scope, supply chain documentation and whether the final fabric performance still fits the garment.
Certification may be relevant, but buyers should read what the certificate covers. A yarn certificate, fabric transaction certificate and finished product claim do not mean the same thing.
- Check recycled content percentage.
- Confirm whether certification covers yarn, fabric or finished goods.
- Ask for transaction documents when required by the customer.
Production variables buyers should not ignore
The same written specification can behave differently when yarn source, knitting tension, dyeing route, finishing recipe or packing changes. This is why a retained standard and production record are useful for repeat orders.
A factory-side review should connect the visible sample with the process that created it.
- Confirm composition, GSM, width and finishing route.
- Check whether the sample was made under the same route planned for bulk.
- Record what changes are acceptable before the order moves to production.
How to approve it in practice
A practical approval should combine physical sample review, measurable tolerances and written notes. If the requirement is subjective, such as handfeel or appearance, a reference sample becomes more important.
For technical points, test method and tolerance should be agreed before bulk fabric is produced.
- Keep one approved sample for comparison.
- Use roll numbers and batch records for traceability.
- Do not change material source or finishing route without review.
- Check bulk fabric after final finishing.
A practical sourcing note
The goal is not to make every fabric discussion complicated. The goal is to make the important risk visible early enough that the buyer and factory can solve it before cutting or shipment.
Questions buyers often ask
Can this be checked only from a photo?
No. Photos can help with communication, but fabric approval needs a physical sample, specification and sometimes test data.
When should this be discussed with the factory?
Before sampling or before bulk approval, especially when the fabric affects fit, appearance, comfort or compliance.
What should be kept for repeat orders?
Keep the approved sample, technical notes, roll records and any test reports connected to the order.
