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 () shown in FIG.
