A polytetrafluoroethylene textile and manufacturing method thereof is disclosed. a pretreatment process is performed on a plurality of polytetrafluoroethylene yarns. In the pretreatment process, a step of extending the polytetrafluoroethylene yarns are extended, the polytetrafluoroethylene yarns are knitted into a polytetrafluoroethylene fabric, the shape of the polytetrafluoroethylene fabric is fixed, and the polytetrafluoroethylene fabric are de-knitted into the polytetrafluoroethylene yarns with a plurality of knit-assisting parts. A second knitting process is performed to knit the polytetrafluoroethylene yarns and a plurality of artificial yarns together to obtain the polytetrafluoroethylene textile. 1. A method of manufacturing a polytetrafluoroethylene textile , comprising steps of:performing a pretreatment process on a plurality of polytetrafluoroethylene yarns, wherein the pretreatment process comprises a step of extending the polytetrafluoroethylene yarns; a step of first knitting the polytetrafluoroethylene yarns into a polytetrafluoroethylene fabric; a step of fixing the shape of the polytetrafluoroethylene fabric; and a step of de-knitting the polytetrafluoroethylene fabric such that the polytetrafluoroethylene yarns are provided with a plurality of knit-assisting parts; andperforming a second knitting process to knit the polytetrafluoroethylene yarns with the knit-assisting parts and a plurality of artificial yarns together to obtain the polytetrafluoroethylene textile,wherein the knit-assisting parts assist the second knitting process to knit the polytetrafluoroethylene yarns and the artificial yarns together.2. The method of claim 1 , wherein the length of the polytetrafluoroethylene yarns are increased in a proportion of 70% to 120% in the step of extending the polytetrafluoroethylene yarns.3. The method of claim 2 , wherein the length of the polytetrafluoroethylene yarns are increased by pulling and twisting claim 2 , and the knit-assisting parts of ...
