The invention discloses a fabric for an air bag and a production method thereof. The average value of ratios of the number of abnormal interweaved points to the total number of the interweaved pointsof each 10 continuous warp yarns and/or weft yarns is larger than or equal to 15 percent in the fabric. Tension difference exists between each 10 continuous warp yarns and/or weft yarns when the fabric is weaved. The invention provides the fabric for the air bag fabric, which can keep basic performance, and has small slippage of a sewed part when the air bag is unfolded as well as good receiving performance and low cost.
