PTFE sewing thread is make from 100% PTFE filament fiber. Because PTFE materials with excellent UV resistance and working lifespan, so PTFE sewing thread has better function than other fiber. At the same time, the outdoor product’s working environment is complex and changeable. So people have to face many troubles of aging and breakage. PTFE sewing thread can adapt to extreme cold, extreme heat, strong UV radiation and long-term wear. It’ll be the best choose for out door application.

Base different production process,PTFE Filament Yarn include two type, Membrane Tore Yarn and Extruded Yarn.
Membrane Tore Yarn, the cross section likes ovalness. After twise process,the breaking force will better. The weakness is hard to contral color difference. It is adequate for construction,membrane structures,etc.
Extruded Yarn, the cross section likes roundness. It’s easy to contral color difference but breaking force lower than membrane tore yarn. It is adequate for clothing textile, sail, outdoor wigwam,etc.
