PURPOSE: To obtain a synthetic fiber filament union cloth, excellent in antistatic performances and having a good touch feeling and provide a method for producting the same.

CONSTITUTION: (1) The characteristic of this synthetic fiber filament union cloth prepared by mixing and weaving warp yarns comprising positively charged synthetic fiber filament yarns and negatively charged synthetic fiber filament yarns with weft yarns comprises the size ratio of the filaments constituting the warp yarns having a relationship of ≥0.5 and ≤3 and alternately arranging the positively charged filaments of the warp yarns and the negatively charged filaments thereof one by one. (2) The characteristic of this method for producing a synthetic fiber filament woven fabric comprises weaving by uring the warp yarns of positively charged filament yarns and negatively charged filament yarns alternately arranged one by one on one beam.
