Tianjin Institute of Industrial Biotechnology, Chinese Academy of Sciences

Recently, the Tianjin Biotechnology Institute of the Chinese Academy of Sciences and Hebei Textiles Supply and Marketing Co., Ltd. jointly developed and promoted the pre-printing and dyeing treatment of boiled and bleached biological enzymes. According to the green and sustainable future development trend of China's textile printing and dyeing industry, according to the low value-added and low-cost operation of the textile market, after continuous research and development, compounding test and process improvement of new textile enzyme preparations, it is finally obtained in the second half of this year. A breakthrough progress has been made to develop a series of environmentally-friendly biological pre-treatment enzyme preparations and supporting technologies that are urgently needed in China's textile printing and dyeing pre-treatment. The process has good matching characteristics for domestic complicated fabric types and current equipment. According to the actual application calculation, the printing and dyeing enterprises use the enzymatic pretreatment process, which will greatly reduce the cost price of energy, time, sewage treatment and additives, thereby enhancing the market competitiveness of printing and dyeing enterprises. In the trial production process, some large textile enterprises in China have given full support, including Tianjin Tianfang Group, Hebei Ningfang Group, Weiqiao Venture Group, Lutai Textile Group, Qingdao Zhifa Textile Group, Shandong Binzhou Sanyuan Home Textiles , Wuxi Qianzhou Weida Needle Textile Co., Ltd., etc. On July 26 this year, he held a press conference on technical achievements in Hebei Ningfang Group, and featured reports in mainstream media such as People’s Daily, Xinhua News Agency, China News Service, China Textile News, and China Textile Herald. Caused a huge response.

The production application of pre-dye bio-textile dyeing pre-treatment of the Chinese Academy of Sciences is reflected in the comparison of the quality of the cloth surface with the traditional alkali process. The comparative values ​​of the pre-treatment production applications of the c16*12 120*60 yarn card dyeing cloth are as follows: table:

The pre-treatment of biological enzymatic method realizes one step and one bath of desizing refining, which can shorten the treatment process and improve the treatment efficiency. At the same time, compared with the alkali method, the biological enzymatic pretreatment process saves steam by 50% and saves 40% of electricity. 50% water, 30% reduction in wastewater COD value.

In summary, through the production and application practices of pre-treatment biological enzymes and processes developed by the Tianjin Institute of Labor and Technology in the Chinese Academy of Sciences, compared with the most widely used desizing enzymes in China, our complex enzyme preparations have the following advantages: 1. One step of desizing and refining After completion, there is no need to do alkali refining treatment after desizing, saving alkali dosage and reducing alkali neutralization and wastewater treatment cost. Second, for the pretreatment of mixed slurry, chemical fiber cloth and other enzymatic methods, the treatment effect of Chinese Academy of Sciences enzyme preparation is more Good, has a unique advantage; Third, the Chinese Academy of Sciences complex enzymes have a better effect on the removal of cottonseed hulls; Fourth, the supporting environmentally friendly oxygen bleaching auxiliaries can reduce the amount of hydrogen peroxide and minimize the damage to the grey cloth on the basis of improving the enzyme treatment effect. In line with the international textile industry's environmental standards.

The project has been strongly supported and valued by the key departments of the Chinese Academy of Sciences, the “13th Five-Year Plan” of the Tianjin Institute of Labor and Technology, and the Hebei National Control Company.
