1. A method of preparing a spinning dispersion, comprising:

  • adding a fiberizing polymer to a polytetrafluoroethylene (PTFE) aqueous dispersion to form a PTFE/Polymer dispersion, wherein the PTFE/Polymer dispersion comprises at least 1% by weight of the fiberizing polymer in relation to weight of the PTFE/Polymer dispersion to no more than 10% by weight of the fiberizing polymer in relation to weight of the PTFE/Polymer dispersion, and wherein the PTFE/Polymer dispersion has a viscosity of at least 50,000 cP.
