Abstract: The present invention provides a method for producing a PTFE fiber that makes it possible, unlike the emulsion spinning process, to obtain a polytetrafluoroethylene (PTFE) fiber, particularly a long PTFE fiber, without using a matrix material, is more productive than conventional production methods such as a slit yarn process, and is capable of enhancing mechanical properties and the degree of freedom in diameter of the obtained fiber. The method for producing the PTFE fiber of the present invention includes the step of reducing a diameter of a string-shape PTFE-containing solid material (a first solid material) by drawing the first solid material at a temperature equal to or higher than a melting point of PTFE. The first solid material can be obtained from a PTFE-containing solid material (a second solid material) containing water and a surfactant, by reducing an amount of the water contained in the second solid material.

Abstract: The present invention provides a method of manufacturing a polytetrafluoroethylene (PTFE) product offering better productivity and a higher degree of flexibility in form of the product to be obtained than the conventional methods of manufacturing a PTFE product, and a method of manufacturing PTFE particle aggregate obtained as an intermediate while manufacturing a PTFE product. According to the manufacturing methods, aggregate of PTFE particles including water and a surfactant is obtained by applying force to a dispersion of PTFE particles containing PTFE particles, a surfactant and water as a dispersion medium, where the force makes the PTFE particles approach or contact with each other. Such a manufacturing method may be carried out, for example, with a chamber (1) shown in FIG. 1.
