The invention provides a fabric drying device of fabric printing and dyeing equipment and belongs to the technical field of machines. By the adoption of the fabric drying device, the problem that existing clothing fabric spraying, printing and dyeing devices are poor in drying efficiency is solved. In the fabric drying device of the fabric printing and dyeing equipment, the fabric printing and dyeing equipment comprises a printing and dyeing chamber and a conveyor belt transversely arranged in the printing and dyeing chamber; the fabric drying device comprises an air outlet barrel arranged over the conveyor belt; an air supply mechanism capable of delivering hot air into the air outlet barrel is further arranged in the printing and dyeing chamber; a bowl-shaped wind baffle right opposite to the air outlet barrel is arranged below the conveyor belt and is fixed into the printing and dyeing chamber, and an opening of the wind baffle faces upwards; a plurality of vent holes are formed in the upper sidewall and the lower sidewall of the conveyor belt in a penetrating mode; and the vent holes located on the same side are evenly distributed in the length direction of the conveyor belt. The fabric drying device has the advantage of high drying efficiency.
