PROOF: PERFORMANCE

There are two compelling reasons why you should switch to the GTT Fluorocarbon-free, water-free dry finish:  Performance and Durability. The GTT performance outperforms both C8 and C6 padded wet finishes. The laundry durability and abrasion resistance outperforms both C8 and C6 padded wet finishes. Need we say more?  

Here is the PROOF. First, for performance, we directly compare polyester fleece that is C8 or C6 treated by a leading apparel brand with the GTT fluorocarbon-free finish. The untreated fabric is the same. 

The Bundesmann Water Repellency Tester provides a grueling rainshower that is estimated to be 200-500x a real rainshower. Compare the C8 and C6 treatment with the GTT treatment. Watch how the rain just runs off the treated face...

High End Silk FabriC

Dry finishing is not just for sports and outdoor performance apparel... How about high end fashion?  The video above shows fine silk fabric that was dry-finished using the GTT technology at 35 Bar pressure (3.5 MPa). This PFC-free, water-free, solvent-free finish provides a water repellent and stain repellent treatment for silk fabric.

Cotton and Poly/Cotton Blends

100% cotton fabric is difficult to treat using dry finishing and cotton/poly blends are difficult to treat using traditional "wet"-based finishing.  Now, both can be treated using the high pressure technology developed by GTT.  Have a look at the video above that demonstrates the viability of this proprietary GTT process.

Interested in treating membrane fabrics?  

 Membrane fabrics have a polyurethane (PU) or e-polytetrafluoroethylene (e-PTFE) membrane for water-proofing. The porous PU or e-PTFE membrane provides for water-proofing, while also allowing water vapor to escape.  This provides better comfort and breathability for the wearer. But, the thin membrane must be protected by covering it with a DWR-coated fabric. If that fabric becomes waterlogged, the membrane will not breathe. Wear and washing often removes the outer DWR coating especially for wet-finished fluorocarbon-based DWR treatments.  

Not so for the GTT PFC-free dry finish DWR treatment as shown in this video.  It holds up better than any C6 or C8 fluorocarbon treatment.  High pressure curing provides an even better protective finish.  

Note the high performance of the Thermally-cured ("TC") fabric cured at 1 Bar pressure and the even higher performance for the "HP" cured sample (10 Bar pressure) and the "Pod" sample (30 Bar pressure).   

This video shows treatment of the face fabric only, without the PU membrane.  To see the treatment of the 3 layer fabric with the membrane used for complete water-proofing, look down at the second video, just below this one.
