The invention provides a method for producing a jacquard-like pattern with a dobby loom. With an original small pattern as a chief source, the method makes progressive combination in a warp-wise arrangement order of original yarn, i.e. advancing a digit number when every N digits are taken, step by step in an orderly way until the end of a cycle, with the N as an amplification factor in the warp direction; meanwhile, progressive combination is conducted in a broadwise arrangement order of the original yarn, i.e. advancing a digit number when every M digits are taken, step by step in an orderly way until the end of a cycle, with the M as an amplification factor broadwise; the produced jacquard-like pattern is N*M times of the original small pattern in area. With both low cost and high efficiency, the method of the invention solves the problem of producing jacquard fabrics on a dobby loom, and also can produce jacquard patterns of different effects.
