The invention discloses a cold pad batch dyeing process for silk broadcloth. The process comprises the following steps of: adding 30g of potassium niobate (KN) type dye into each liter of water, uniformly stirring, conveying into a liquid rolling groove, and keeping the temperature of between 25 and 45 DEG C; immersing silk broadcloth fabric in dye liquor in the liquid rolling groove, soaking under the state of movement for 55 minutes, pulling the silk broadcloth fabric away from the dye liquor, allowing the silk broadcloth fabric to pass through a pair of uniform rollers, reeling and rolling in open width by a central drive roller on a rolling frame, after the silk broadcloth fabric is coiled, tightly wrapping the silk broadcloth fabric and a spindle head by using a film, and placing at the temperature of 30 DEG C for 6 to 9 hours; and washing by using clean water, placing in water containing soda and soaking, taking the silk broadcloth fabric out, washing by using water once, and drying to obtain the silk broadcloth. In the process, the damage to the silk broadcloth is small, silk abrasion is reduced, the color and luster are uniform, and filling and strip imprint of the fabric can be reduced; and the process has the advantages of capability of saving water and energy, high dye utilization rate, low investment on equipment, simplicity and the like and is easy to operate.
