Peng Yanli: Cotton Fabric Energy Saving Printing And Dyeing Changing Bureau

In September 24th,

The on-site promotion of "cotton fabric low temperature continuous scouring and bleaching process" jointly organized by the Ministry of Textile Industry Federation of science and technology development, China printing and dyeing industry association, China Household Textile Industry Association and textile optical technology education foundation was held in Yongji, Shanxi.

Chen Zhihua, chairman of the China dyeing and printing industry association, honorary chairman Li Jinbao, Secretary of the textile science and technology education foundation, Zhang Cui Zhu, and many representatives of printing and dyeing and home textile enterprises attended the event.

"Low temperature continuous rapid cold bleaching and bleaching technology for cotton fabric" has developed a fast, low temperature scouring and Bleaching Auxiliaries with high efficiency, dispersing, emulsifying, permeating and stabilizing. A continuous one bath one-step process for cotton fabric has been developed. It has made an attempt to achieve energy saving and consumption reduction for textile dyeing and finishing, and has achieved remarkable results.

Peng Yanli, Deputy Secretary General of the China Textile Industry Federation and director of the Ministry of science and technology development, commented on this achievement.

Chen Zhihua, chairman of the China dyeing and printing industry association, honorary chairman Li Jinbao, Secretary of the textile science and technology education foundation, Zhang Cui Zhu, and many representatives of printing and dyeing and home textile enterprises attended the event.

according to

Chai Huazhen, chairman of Cai Jia dyeing and Printing Co., Ltd. introduced that the cotton fabric's low temperature continuous scouring and bleaching process decreased from 12~24 hours to 75~90 minutes compared with the conventional cold reactor process. Compared with the conventional two step gas evaporation process, the temperature of the traditional bleaching process decreased from 100 to 40 degrees, and the consumption of steam, water and chemical products decreased by more than 50%, and the power consumption was reduced by more than 40%. Breaking through the disadvantages of the traditional cold reactor technology and the high energy consumption of the continuous steaming process, the pH value of the scouring and bleaching effluent dropped from 12 to 7~8, and the total amount of COD decreased by more than 60%.

The project is listed as the national Torch Plan industrialization demonstration project in 2013, the first prize of the textile science and technology award of "textile light" in 2014.

Awarding project.

At the inspection site, Chen Zhihua said that from the "11th Five-Year" to "12th Five-Year" period, the energy saving and emission reduction level of the printing and dyeing industry has been improving, which stems from the progress of science and technology.

The company's R & D investment in this area is driving the development of the industry, and Choi Jia is a good example.

The pretreatment level of cotton fabric has a great impact on the rear track. This has been a difficult problem for the textile industry. Cai Jia's technology has gone out of a completely new way. From the production process to the wastewater treatment process, it has great significance for the development of the industry.
