摘要: Composite fibers useful for preparing diaphragms are prepared by (a) mixing a PTFE or PTFE copolymer dispersion or powder with a finely divided inorganic material and a fiber forming material, (b) shear heating the resulting mixture to a temperature at which sheared to PTFE or PTFE copolymer becomes flowable without showing signs of decomposition while removing the dispersion medium, if a PTFE or PTFE copolymer dispersion is used, (c) cooling the mixture to below 70° C., (d) mix shearing the mixture at below 70° C. to form composite fibers.
