Material Dossier -- 2026

REPREVE®

Bottle-derived recycled polyester draws feedstock out of an existing bottle-to-bottle loop, which does not make the recycled content untrue but weakens a broad circularity claim. Microfibre shedding is addressed by none of the certificates this fibre holds.

Documented Constraints & Untested Conditions

Bottle-derived rPET is increasingly challenged on the grounds that it draws feedstock out of an existing closed bottle-to-bottle loop rather than creating new circularity. That argument does not make the recycled content untrue, but it does change how defensible a broad ‘circular’ claim is. Microfibre shedding is not addressed by any certificate this product holds.

No independent test record on file. Material Primer has not bench-tested this product. The figures above are the supplier’s own published specification. Treat them as a starting point for your own testing, not as verified performance.

Verification Boundary -- What This Page Does Not Claim

This dossier compiles the supplier's published specification, the stated scope of certificates held, and referenced standards. It does not represent independent laboratory testing, production batch monitoring, or transaction data. Suitability judgements derive from the documents above, not from bench tests.
