To produce a pile fabric without expressing intervals between rows of the piles as groove-like appearance and having good appearance and high commercial value as carpets by alternately forming loop piles in the loop pile part.

This production of a pile fabric is to interweave alternately arranged two species of pile wrap yarns L1, L2 in a pile part to engage with ground weft yarns A struck into the upper side of each of core warp yarn Z by alternately passing over every other ground weft yarn A1 or A2 and alternately passing under every other ground weft yarn A2 or A1, and arrange the ground weft yarns A2, A1 to alternately approach and separate, thus, form the loop piles with the pile warp yarn L1 and the loop piles with the pile weft yarn L2 by shifting their sites to form a shifted state biasing in the weaving direction by alternately approaching and separating the engaged spots passing under the ground weft yarns A2, A1.
