PTFE filamentyarn is the monofilament with a certain continuous lengthover 10000 meters.

    Density is in range of 200dtex-1500dtex with higher strength, elongation and better flexibility.

    Our standard specification is 500dtex or 450den. 

    At present, there are two kinds of production process for the PTFE filament yarn. That is "extruding method" namely round filament yarn and "splitting method" namely flat filament yarn.

    Usually, Splitting" PTFE filament yarn namely flat filament yarn. 

    PTFE flat filament yarn are formed from PTFE film by drafting, sintering and cutting. It is suitable for making PTFE scrim.

    However, "Extruding" PTFE filament yarn namely round filament yarn is suitable for making PTFE sewing thread.
