Yarn Manufacturing Programme
Recycled (rPET) and Regenerated Polyester Yarn Manufacturer — Türkiye
Recycling is not a label but a choice of route. We run both the mechanical and the chemical route; they process different waste, deliver different strength and suit different programmes. This page puts them side by side.
The mechanical route washes, flakes and re-melts post-consumer PET bottles. It is the most common and most accessible path, but it carries a technical cost that we do not hide in the table: tenacity of 2.7–3.7 cN/dtex sits below virgin polyester's 3.6–4.5 band. The reason is chemical — PET is hygroscopic, moisture in the chain hydrolyses the ester bond at melt temperature and intrinsic viscosity falls. In practice, that makes machine tension and batch consistency more critical.
The chemical route closes that gap by a measurable margin. Depolymerisation breaks PET back to its monomer and repolymerisation re-extends the chain, compensating the loss of intrinsic viscosity and lifting tenacity to 3.0–3.8 cN/dtex — above mechanical rPET and just below virgin. Its second advantage is in the feedstock: it can process coloured and mixed waste, which the mechanical route cannot.
Coverage differs between the two routes, and hiding that difference would mislead the buyer. Mechanical rPET runs in 50, 75, 100 and 150 denier; the finest microfilament constructions (144 and 288 filaments) are not part of this family. Chemically regenerated runs in 50, 75 and 100 denier; 150 denier is not available in that family.

The route is chosen with your claim and your performance target
Which route is right depends on the recycled-content claim you need to make, the tenacity you are targeting and your colour programme. GRS 4.0 and RCS 2.0 chain of custody apply — these documents evidence traceability of the material, not performance, and it matters not to confuse the two. Recycled content and certification scope are confirmed with the quotation. Quotation requests are answered within 2 business days.

Frequently asked questions
Should I choose mechanical or chemical recycling?
If the claim and the cost are your priority, mechanical rPET is the common and accessible path. If tenacity and colour flexibility matter more, chemically regenerated fits better: its tenacity sits above mechanical rPET and it can process coloured and mixed waste. The decision should be made together with the performance target.
What is the difference between GRS and RCS?
Both are chain-of-custody standards and evidence the traceability of recycled content. GRS additionally carries social and environmental criteria and chemical restrictions; RCS focuses on content verification alone. Neither certifies the performance of the fabric — they certify where the material came from.
How high can you take the recycled content?
The share is set against the product and the performance target and is documented through the chain of custody. The exact figure is confirmed with the quotation; every claimed share has to be backed by the certification scope.
Which denier and filament options exist in rPET?
Mechanical rPET runs in 50, 75, 100 and 150 denier. The finest microfilament constructions — 144 and 288 filaments — are not part of this family; the finest option in rPET is 96 filaments.
Which bands does the chemically regenerated route cover?
It is produced in 50, 75 and 100 denier. There is no 150 denier in that family; where recycling is required in that band, the mechanical rPET route is used.
Can recycled yarn be blended with virgin in one fabric?
It is technically possible, but the two fibres differ in tenacity and shrinkage behaviour, so the heat-setting window has to be set accordingly. From a claims standpoint, blended use requires the recycled share to be calculated correctly through the chain of custody.
