Cleaning production process in dyeing and printing industry

Abstract

The invention relates to a production process in textile dyeing and printing industry, which provides a cleaning production process and equipment in the dyeing and printing industry. The process comprises the processes of singeing, desizing, boiling, bleaching, mercerizing, dyeing / pattern printing, tidying (rinsing) and finished product obtaining, wherein in the work procedures of desizing, boiling, dyeing / pattern printing and tidying (rinsing), 20 to 50 KHz ultrasonic waves are adopted for irradiation. Correspondingly, ultrasonic wave generators are arranged in production equipment such as a desizing tank, a vapor steaming box, a dyeing cylinder, a rinsing box and the like. The cleaning production process and the equipment thereof in the dyeing and printing industry provided by the invention adopt the ultrasonic wave technology, improve the dye utilization rate and the dyeing efficiency, reduce the dye consumption, enhance the dye coloring and color fixation effect, accelerate the permeation and the moistening of the dye on the textile, short the dyeing time, reduce the waste water discharge quantity of the dyeing and printing industry, improve the biodegradability of the dyeing and printing waste water, reduce the pollution of an MBR system, improve the cleaning effect, and reduce the pollution.

Description

technical field [0001] The invention relates to a production process in the textile printing and dyeing industry, in particular to a clean production process and equipment in the printing and dyeing industry. Background technique [0002] In recent years, my country's printing and dyeing industry has experienced unprecedented rapid development, and its share of global production capacity has continued to rise, making my country the largest country in the world's printing and dyeing industry. However, textile dyeing and finishing requires a lot of water. Whether it is desizing and scouring in pre-treatment, or rinsing after dyeing to remove floating impurities, a lot of water is needed to complete. Therefore, the printing and dyeing industry is a water-consuming industry. , The "big household" of sewage discharge, the pressure on my country's water environment cannot be underestimated. [0003] At present, the treatment of printing and dyeing wastewater is mainly based on cen...
