Sixone offers an AI‑driven platform that uses spectroscopy and machine‑learning to fingerprint mixed‑fiber garments and generate reaction recipes that selectively release polyester. The extracted polymer is repolymerized into high‑purity PET pellets with properties matching virgin polyester, allowing apparel brands and textile manufacturers to incorporate certified recycled feedstock without modifying existing production lines.

Problem
Blended post‑consumer textiles contain polyester mixed with other fibers, dyes, and chemical finishes, making them chemically complex and unsuitable for conventional recycling streams. As a result, only about 1 % of textile waste is recycled while the vast majority ends up in landfills or degrades into microplastics.
Solution
Sixone applies a data‑driven, AI‑enabled platform to identify the precise chemical composition of mixed‑fiber garments and to execute targeted reactions that selectively liberate polyester. The extracted polyester monomers are repolymerized into high‑purity PET pellets that meet the performance specifications of virgin polyester and recycled bottle feedstock. These pellets can be directly incorporated into existing textile manufacturing processes, allowing apparel brands to close material loops without redesigning their supply chains. By continuously expanding a chemical fingerprint database, the system improves yield and reduces processing costs across a wide range of fabric blends.
Target Audience
Primary customers are apparel brands and textile manufacturers seeking certified recycled polyester to meet circularity commitments, as well as supply‑chain partners looking to integrate recycled feedstock without altering existing production processes.
Features
- Advanced spectroscopy creates detailed chemical fingerprints of each textile batch for accurate material identification.
- Proprietary machine‑learning models predict optimal reaction conditions and generate “recipe” recommendations for each blend.
- Targeted chemical reactions selectively break polyester bonds while preserving non‑polyester components, enabling efficient separation.
- Repolymerization step produces PET pellets with melt flow and tensile properties equivalent to virgin polyester and recycled PET bottles.
- Scalable processing workflow integrates with standard textile manufacturing lines, requiring no equipment modifications for end users.
- Continuously updated materials database expands coverage to new fiber combinations and performance finishes, improving extraction yields over time.
- End‑to‑end data pipeline ensures traceability, quality control, and compliance with industry standards for recycled content.
