Printing and dyeing process for terylene washable energy-saving antibacterial fabric

The invention provides a polyester washable energy-saving antibacterial fabric printing and dyeing process which comprises the following steps: pre-setting on a setting machine according to the requirements of textiles, reasonably controlling tension, overfeeding and the temperature of each section of drying oven, and producing according to the process of 190-200 DEG C * 30-90 seconds; polyester and spandex are printed on the polyester and spandex knitted fabric through a printing and dyeing device, and after the polyester and spandex knitted fabric is preset, a dyeing and antibacterial one-bath process is carried out; dehydrating the cleaned textile, spreading the fabric, and dehydrating at the rotating speed of 500 revolutions * 5 minutes to ensure the flatness of the fabric surface; and finished products are shaped and packaged after being knitted. The anionic antibacterial agent is added according to the process when the polyester textile is dyed, and is dyed in one bath with the disperse dye, so that one
