| Abstract: | The structure and physical and chemical properties of polytetrafluoroethylene(PTFE) fiber were introduced.The manufacturing techniques for PTFE fiber were described in details,including carrier spinning(wet spinning and dry spinning),paste extrusion spinning,melt spinning,fissure spinning.The advantages and disadvantages of these spinning techniques were compared.Carrier spinning process was a mature technique for PTFE fiber,especially for low-linear density fiber.The application of PTFE fiber was described in the fields of filtration material,medical material,sealing packing and textile industry.It was pointed out that the key to China PTFE fiber development should be the innovation and development of novel manufacturing techniques and the improvement of PTFE fiber quality and output. |
