What recycled polyester means in dog collars
Recycled polyester is a PET-based polyester fibre whose raw material comes from recycled plastic streams rather than virgin petrochemical feedstock.
The material remains chemically polyester — the recycling process does not create a new fibre class; it remains the same PET-based polymer type, only with recycled instead of virgin input. In collar context, the term typically refers to the textile or webbing layer, not automatically the whole product. Recycled polyester is not a catch-all term for every recycled synthetic fibre. A broader classification of collar materials is available in the Dog collar material overview.
How to place PET, rPET, and REPREVE® correctly
PET is the base polymer; rPET is the recycled feedstock derived from PET streams. Recycled polyester is the textile end product of this process path. REPREVE® is a trademarked fibre family within the recycled polyester category — the name identifies a trademarked fibre family within the category, not a separate material type. Textile communication around dog collars often collapses these levels; the table below places them separately.
| Term | Classification |
|---|---|
| PET | Thermoplastic base polymer; source material for yarn and webbing |
| rPET | Recycled PET feedstock from post-consumer and post-industrial streams |
| Polyester yarn (recycled) | Textile output after converting rPET into fibre and yarn |
| REPREVE® | Trademarked fibre family within the category — not a generic term for rPET |
| Application role in collar | Canvas overlay or webbing — not automatically the full construction |
rPET is used across several industries; in collar production, the textile component is the typical point of application.
What recycled polyester does not mean
Recycled polyester ≠ Regenerated nylon — polyester and nylon are two separate polymer families: polyester is based on PET, nylon on polyamide chains. The recycling process does not change the polymer class; it produces the same PET-based polymer type from recovered input. The category Regenerated nylon describes the polyamide stream — not PET-based fibres.
Recycled polyester ≠ REPREVE® — REPREVE® is a trademarked fibre family within the recycled polyester category, not a generic label for the full class. Not every rPET fibre carries REPREVE® certification; not every REPREVE® delivery ends up as webbing in a finished collar.
Recycled polyester ≠ fully recycled collar — a recycled claim applies to the named material component, not to the whole product. The canvas overlay or webbing may contain recycled polyester while hardware, closures, and labels follow different material paths. The recycled statement refers to the specific textile component — a whole-product claim requires cross-component documentation.
At Barklin, recycled polyester appears as a REPREVE® canvas overlay — the component records 5.85 g at 50% recycled content in size M — and as recycled polyester sewing thread. Both figures apply to the respective component, not the complete collar. The Supply chain section of the transparency report provides further detail.
