Revolutionary breakthrough in wool strip shrink-proof technology

Since July, although many provinces and cities including Jiangsu have been hit by heavy rains, some railways and passenger lines have even temporarily suspended or line adjustments. However, a revolutionary breakthrough in the wool textile industry attracts new technology exchanges. A large number of woolen textile manufacturers and application companies from all over the country gathered in Changshu, Jiangsu Province to witness the innovation brought by this technology.

This technology is the day the United States by the Tianjin Green Technology Co., Ltd., Tianjin University of Technology, Changshu Xinguang tops Treatment Co., Ltd., Wuhan Textile University, Bazhou East Coastal Technology Co., Ltd. and other units jointly undertaken by China Textile Industry Association scientific and technological guidance project “Key technology and industrialization of bio-enzyme continuous wool rapid shrinkage prevention”.

In order to speed up the application of this technology, on July 6, the China Wool Textile Industry Association organized a “2016 Symposium on the Successful Exchange of Tops for Chlorine Free Processing” in Changshu, Jiangsu. Zhou Lingqun, deputy mayor of Changshu City, Jiangsu Province, Huang Shuyuan, president of China Wool Textile Industry Association, Cao Guofen, secretary of the Party Committee of Guli Town, Changshu City, Gao Ping, deputy mayor of Guli Town, Changshu City, General Manager of Changshu Xinguang Top Bar Processing Co., Ltd., Jiande De, Tianjin Luyuan Tianmei Technology Zhang Weimin, general manager of the company, and representatives from relevant industry organizations and enterprises attended the meeting.

Where is the revolutionary breakthrough?

Yao Jinbo, Dean of the School of Chemical Engineering, Wuhan Textile University, introduced the research and development background of the biological enzyme wool shrinkage prevention technology. He said that at present, the most widely used wool shrinkage treatment process is the chlorination shrinkage prevention method, which has the advantages of low cost and good shrinkage prevention effect, but the organic halide AOX (absorbable organic halogenation) produced by the treatment process. ()) will seriously pollute the environment, and domestic and foreign have adopted legislation to limit AOX emissions.

Moreover, its residual chlorine is difficult to clean and does not meet the processing requirements of ecological textiles. With the development of science and technology and the enhancement of human environmental awareness, the traditional anti-shrinkage treatment of chlorination has been gradually replaced by new environmental protection methods. The pursuit of more energy-saving, low-cost, good quality anti-shrinkage methods must become the future research in the textile field. trend. The use of biological enzyme technology to process textiles is one of the development directions. The biological enzymatic method is not only ecologically friendly, but also has mild reaction conditions, high catalytic efficiency, safety, easy operation, and easy biodegradation of waste liquid, and is most likely to replace the chlorination shrinkage prevention process.

Yang Wanjun, deputy general manager of Tianjin Luyuan Tianmei Technology Co., Ltd. introduced that Luyuan Tianmei has been studying the continuous processing method and process of biological enzyme processing wool tops since 2008. The successful application of this technology has solved the long-term troubled hair chlorination treatment caused by the industry. Serious environmental problems such as AOX emissions, but also solve the problem of pollution in the workshop production environment caused by chlorine leakage. Yang Wanjun introduced that the technology has been successfully applied to industrialization in Changshu Xinguang Top Bar Processing Co., Ltd. for one year.

Just one day before the meeting, the technology also passed an appraisal meeting organized by the China National Textile and Apparel Council. After questioning and discussion, the appraisal committee unanimously agreed that the project based on the "double catalysis" theory, developed wool fiber modified high-efficiency biological enzymes and activators, significantly improved the reaction efficiency of biological enzymes and wool fiber scales, and developed wool fiber bio-enzymes. Continuous rapid shrinkage prevention process technology, focusing on solving the technical problems of uniformity and stability in continuous processing; developing key equipment for wool fiber bio-enzyme processing, and establishing a continuous processing production line, the first realization of wool tops enzymes The industrialization of continuous rapid shrink-proof processing has achieved the green processing of wool shrink-proof.

Chen Guoqiang, dean of the Textile College of Suzhou University, read the appraisal results of the “Key Technology and Industrialization of Bio-Enzyme Continuous Wool Rapid Shrink Prevention” project. He said that the technology has reached the international advanced level and reached the international leading level in the rapid continuous shrinkage prevention technology of wool tops, and the wool fiber processed by this technology has excellent performance, stable quality, advanced and mature technology, and has broad promotion. And application prospects, it is recommended to speed up the promotion of applications to meet market demand.

The application party says this

Yu Jiande, general manager of Changshu Xinguang Top Bar Processing Co., Ltd. said that after one year of trial operation, Xinguang has successfully developed a continuous bio-enzyme shrink-proof production line and realized continuous industrial production and formed mass production capacity.

“Xingguang Company uses the synergistic effect of bioactivator and protease to modify the surface scale of wool in a very short time to achieve the continuous processing of shrink-proof. The wool after the treatment, the shrinkage test can reach the international wool machine Washable standard, shrinkage can be controlled at 0~-8%; no chlorination during processing, solves the problem of emitting AOX in the process of chlorine shrinkage prevention; the physical indexes of wool are similar to those of chlorinated wool, and The product has excellent anti-pilling performance and excellent dyeing performance. At the same time, the treated wool does not have excessive regular reflection light, and the gloss is closer to the original ecological wool.” Jian Jiande said.

As a first-line application, Qi Jiande proposed that the key technology of bio-enzyme continuous wool rapid shrinkage prevention should increase research and development efforts in terms of cost reduction and stable process in the future, and select more efficient and cheap chemical additives to greatly reduce production costs. And optimize the process to further improve product quality, integrate a set of intermediate control and testing methods for industrial production, and stabilize product quality.

How do experts view this technology?

Huang Shuyuan, president of China Wool Textile Industry Association, first highly praised the significance that this technology will bring to the development of the industry.

She said that China is the world's largest wool processing and processing country and wool consuming country. The world's most advanced wool spinning technology is also in China. The successful research and development of "bio-enzyme continuous wool rapid shrink-proof key technology and industrialization" will lead China. The woolen industry is on a higher level. Huang Shuyuan pointed out that during the "Twelfth Five-Year Plan" period, China's wool textile industry has made certain achievements in energy conservation and emission reduction , and has promoted a large number of new technologies for energy conservation and emission reduction. During the “ Thirteenth Five-Year Plan” period, in order to fully implement the development concept of “innovation, coordination, green, openness, and sharing” and promote the supply-side reform of the wool textile industry, the green development of the wool textile industry still has to undergo a severe test. The industry needs bio-enzyme continuous wool fast. More revolutionary technologies like anti-shrinking key technologies.

In addition, Huang Shuyuan also introduced the operation of the wool textile industry from January to May. Overall, from January to May, the wool textile industry was generally stable. The demand situation of the two markets declined compared with the same period of last year, but the decline was somewhat adjusted. The growth rate of the efficiency level dropped from the previous year, and the burden on enterprises increased.
