Embodiment Construction
[0021] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.
[0022] A clean production process in the printing and dyeing industry, including singeing - desizing - scouring - bleaching - mercerizing - dyeing / printing - finishing (rinsing) - finished product process and wastewater treatment process, wherein,
[0023] In the process of desizing and scouring, use 20-50KHZ ultrasonic irradiation at room temperature, and in the dyeing / printing process, use 20-50KHZ ultrasonic irradiation on the fabric soaked in dye solution; after the fabric is dyed, it needs to Rinse to remove undyed, unfixed or hydrolyzed dyes. In the finishing (rinsing) process, use 20-50KHZ ultrasonic waves in the rinsing box to irradiate to promote the washing effect. The printing and dyeing wastewater produced in the desizing, scouring, bleaching, dyeing / printing and finishing processes is irradiated with 20-50KHz ultrasonic waves before the ...
