Green is the “must-answer” for the wool textile industry

Huang Shuyuan said that with the transfer of the world's wool textile industry to China, China is currently the world's largest wool textile production and processing country, but it also brings a series of problems such as pollution. In order to realize the green and healthy development of China's wool textile industry, a large number of enterprises have invested a lot of research and development and investment, and have achieved certain results. In particular, the industrialization of the continuous processing and treatment process of the chlorine-free anti-shrinking hair strip by the biological enzymatic method not only realizes the economic effect of the enterprise, but also reflects the social responsibility of the industry.

When talking about energy-saving and emission reduction in the wool textile industry, Huang Shuyuan pointed out that during the “Twelfth Five-Year Plan” period, the wool textile industry actively implemented the “Wool Industry Water Pollutant Emission Standard ” and the “Textile Dyeing and Finishing Industry Water Pollutant Emission Standard” and promoted it. A large number of advanced technologies for energy saving and emission reduction, such as small bath ratio dyeing, low temperature dyeing, high-efficiency top coat washing machine, post-finishing washing and shrinking machine and other water-saving technologies.

During the “ Thirteenth Five-Year Plan” period, the wool textile industry will actively implement the development concept of innovation, coordination, green, openness and sharing, promote the supply side reform of the wool textile industry, and accelerate the development and promotion of key technologies for energy conservation, emission reduction and resource recycling. Save resources and reduce pollutant emissions. In particular, it will speed up the research and development of advanced technology for energy saving and consumption reduction, such as scouring, wool product recycling, chlorine-free shrinkage prevention, less watermark dyeing, and zero chemical emissions.

The project can achieve anti-shrinking green processing of wool

The “Key Technology and Industrialization of Bio-Enzyme Continuous Wool Rapid Shrink Prevention” approved by Tianjin Lianyuan Tianmei Technology Co., Ltd., Tianjin University of Technology, Changshu Xinguang Top Bar Processing Co., Ltd., Wuhan Textile University, Bazhou City Binhai Oriental Technology Co., Ltd. and other units jointly undertake and are guided by the China Textile Industry Federation. Based on the theory of “double urging method”, the project developed wool fiber modified high-efficiency biological enzymes and activators, which significantly improved the reaction efficiency of biological enzymes and wool fiber scales; developed a rapid anti-shrinkage treatment technology for wool fiber biological enzymes. It has solved the technical problems of uniformity and stability in the continuous processing process; developed the key equipment for wool fiber bio-enzyme processing, built a continuous processing production line, and realized the industrialization of the continuous rapid shrink-proof processing of wool tops. , reached the green processing of wool shrink-proof. The overall technology of the project has reached the international advanced level, and has reached the international leading level in the continuous anti-shrinkage treatment technology of wool tops. At the same time, the wool fiber fiber processed by the project has excellent performance, stable quality , advanced and mature technology, and has broad application and application prospects.

Yao Jinbo introduced the key technology of bio-enzyme continuous wool rapid shrinkage prevention: "At present, the most widely used wool shrinkage treatment process is the chlorination shrinkage prevention method. This process has the advantages of low cost and good anti-shrinkage effect, but it is processed. The organic halide AOX (absorbable organic halide) produced in the process will seriously pollute the environment, and domestic and international regulations have adopted legislation to limit AOX emissions. Moreover, the residual chlorine is difficult to clean and does not meet the processing requirements of ecological textiles. At present, there are many methods for anti-shrinkage of chlorine-free wool, such as potassium permanganate method, peroxide method, ozone gas treatment method, biological enzymatic method, low-temperature plasma treatment method, liquid ammonia method, and natural high polymer and nano material finishing method. Etc. Among them, the biological enzymatic method is not only ecologically friendly, but also has mild reaction conditions, high catalytic efficiency, safety, easy operation, easy biodegradation of waste liquid, and optimal replacement of chlorination shrinkage prevention process. In the process of implementation, biological enzymatic wool The rapid anti-shrinking technology has the function of quickly completing the scale modification, achieving anti-felting, and achieving the TM31 (585A)-8% technical requirement, while achieving the anti-shrinking effect, the maximum To reduce the uniformity of wool fiber damage and shrinkage treatment. In the continuous production, the stability of the working fluid, the stability and reproducibility of wool processing quality, designed a new processing idea - biological enzyme continuous wool fast Key technology for shrink-proof. The dyeing and spinnability of the products produced by this production process are up to the level of chlorinated similar products, and the anti-pilling level is higher than similar products.

Full promotion still needs to be strengthened

Yang Wanjun said in the introduction of the chlorine-free shrink-proof wool process: "Lvyuan Tianmei has spent nearly one year working closely with Changshu Xinguang Tops Co., Ltd. to slightly modify the existing chlorination stripping equipment and use the green source. Tianmei's auxiliaries achieve the effect of stripping scales under the original process conditions, thereby realizing the industrialization process of chlorine-free anti-shrinking tops, and named this process 'Evexin' process.” Yang Wanjun said that the next step will be Improve the rapid online monitoring technology in the production process, promote the formulation of international standards, promote the globalization of the project, and further promote the research on reducing costs, improving production lines and comprehensive utilization of wastewater discharge.
