Special antistatic PTFE base fabric and preparation method thereof

The invention belongs to the technical field of PTFE base fabric, in particular to a preparation method of special antistatic PTFE base fabric. The preparation method comprises the following steps ofS1, preparation of PTFE yarns: melt-blowing a PTFE raw material at high temperature into silk, and thus making into PTFE round silk; merging two pieces of PTFE round silk into an initial strand, and merging multiple initial strands into the PTFE yarns; stretching the PTFE yarns in an anti-untwisting device and twisting the PTFE yarns into reels; S2, preparation of metal yarns: twisting stainless steel fiber and cotton fiber into the metal yarns and making into reels; S3, preparation of the special antistatic PTFE base fabric: after the PTFE yarns and metal yarns on the multiple reels are drawn, winding strips onto a drum in warp direction proportion; and weaving the PTFE yarns and metal yarns on the reels with the yarns on the drum by a loom in weft direction proportion, and thus preparingthe special antistatic PT
