Cotton Fabric Energy Saving Printing and Dyeing Change Bureau

“Cool fabric low-temperature continuous rapid cold mixing and bleaching process technology” has developed high-efficiency dispersing, emulsifying, infiltrating and stable fast low-temperature bleaching auxiliaries, and achieved a high-efficiency and low-temperature continuous one-bath decoiling and bleaching process for cotton fabrics. Dyeing and finishing has been a useful attempt to achieve energy conservation and consumption reduction. Significant results have been achieved. After the identification, the technology has reached the "leading international level." Peng Yanli, deputy secretary-general of the China Textile Industry Federation and director of the Science and Technology Development Department, commented on this achievement.

On September 24th, the "Cotton Fabric Cryogenic Continuous Bleaching Process" on-site promotion activities jointly organized by the China Textile Industry Federation Technology Development Department, the China Printing and Dyeing Industry Association, the China Home Textile Industry Association, and the Textile Light Technology Education Conference were held. Yongji City, Shanxi Province was held.

Chen Zhihua, president of the China Printing and Dyeing Industry Association, honorary president Li Jinbao, Zhang Cuizhu, secretary-general of the Textile Light Technology Education Association, and representatives of many printing and dyeing and home textile companies attended the event.

According to the introduction of Cai Jiazhen, chairman of Shanxi Caijia Printing and Dyeing Co., Ltd., the low-temperature continuous bleaching and bleaching process of cotton fabrics reduces the stacking time from 12 to 24 hours to 75 to 90 minutes compared to the conventional cold-reactor process. Compared with the conventional two-step steaming process Reduce the temperature of traditional bleaching and bleaching process from 100°C to 40°C, reduce the consumption of steam, water, and chemical products by more than 50%, reduce the power consumption by more than 40%, and break through the traditional cold reactor process with low efficiency and continuous steaming The disadvantages of the high energy consumption of the process are that the pH of the bleaching wastewater is reduced from 12 to 7-8, and the total COD is reduced by more than 60%. The project was listed as the 2013 National Torch Program Industrialization Demonstration Project, and the “Light of Textile” 2014 China Textile Spinning Association Science and Technology Award was awarded the first prize.

At the inspection site, Chen Zhihua said that from the “Eleventh Five-Year Plan” to the “Twelfth Five-Year Plan” period, the level of energy-saving and emission reduction in the printing and dyeing industry has been increasing, which is due to advances in science and technology. The investment in R&D in this area has driven the development of the industry. Caijia is a good example. The pre-treatment level of cotton fabrics has a great influence on the back lane. This has always been a problem that has plagued the textile industry. This technology of Caijia has embarked on a completely new path, from the production process to the wastewater treatment process, all of which are of great significance to the development of the industry.
