## Key takeaways

- Mono-material functional fabrics build every layer — face, membrane, and backing — from the same or a compatible polyester family, such as a polyester face and backing paired with a TPEE membrane, unlike traditional fabrics that mix incompatible materials like nylon, PU/PTFE, and polyester.
- Because every layer shares compatible chemistry, mono-material fabrics can be 100% closed-loop recycled, while traditional multi-layer laminates are nearly impossible to separate and recycle at end of life.
- Kae Hwa pairs this mono-material approach with solvent-free lamination to cut VOC emissions and offers GRS (Global Recycled Standard) certified materials as part of its broader sustainability program.

## Frequently asked questions

### What is a mono-material functional fabric?

A mono-material functional fabric is built entirely from the same or a compatible polymer family, such as a polyester face and backing paired with a TPEE membrane, instead of mixing incompatible materials like nylon, PU/PTFE, and polyester. Because every layer shares a compatible chemistry, the finished fabric can be fully recycled in a closed loop rather than becoming unrecyclable waste like traditional multi-layer laminates.

### Does switching to a mono-material fabric mean sacrificing performance?

No — TPEE-based mono-material laminates remain highly flexible and thermally stable while still delivering strong hydrostatic resistance and moisture vapor transmission, so recyclability doesn't come at the cost of performance.
