The invention provides a fabric printing production line, and belongs to the technical field of machines. The fabric printing production line comprises a rack, a fabric unreeling device for releasing fabric is arranged at one end of the rack, and comprises a first mounting plate and a second mounting plate which are fixed to the rack, an unreeling shaft is arranged between the first mounting plate and the second mounting plate, one end of the unreeling shaft penetrates the first mounting plate, an unreeling roller cylinder is detachably fixed to the unreeling shaft, and a drive motor used for driving the unreeling shaft to rotate is further fixed to the rack; the production line is characterized in that a conveying mechanism for traction conveying of fabric, multiple printing devices for different-dye printing on fabric, a drying device for drying the printed fabric and a neatening device for neatening the dried fabric are arranged on the rack in sequence. The production line has the beneficial effect that the fabric can be subject to assembly printing, and the printing efficiency of the fabric can be improved.
