Science & Innovation

Lifting nylon beyond what it's ever done

01
Monomaterial Design
Every component - yarn, trim, thread - is nylon-6. No blends, no contamination, no compromise on recovery.
02
On-Body Stretch
Patented molecular design delivers performance without spandex - tunable from 20-70% by RTV tech.
03
Infinite Recovery
Nylon-6 depolymerizes back to caprolactam and regenerates to virgin-grade material. Same quality, infinite cycles.
Monomateriality

Materials built to come back

One material, no contaminating blends. Everything that moves through our system is 100% recyclable by design - and we help you build it into your products.

01
Yarn
Production-ready nylon yarn. Drop-in replacement, fully recyclable.
02
Fabric
Finished monomaterial fabric with stretch. Ready for cut and sew.
03
Pellets
Regenerated nylon for injection molding and extrusion.
04
Prototypes
Prove out monomaterial concepts before production.

Material Management

End of life is just the beginning

We accept all types of fabrics and materials for recycling - not just nylon. End-of-life materials come back to us and are reused as-is or are recycled into valuable materials.

01
Collection
End-of-life recovery from brands, manufacturers, and waste streams.
02
Reprocessing
End-of-life textiles are recycled into valuable inputs for next-life markets.
03
Regulatory Risk Removal
Verified take-back pathway. EPR, SB 707, EU regulations covered.
Sort and export facility
Baled textiles in warehouse
