Biological Enzyme Continuous Wool Fast Shrinking Technology Eliminates Safety Concerns

1 years ago, the birth of Princess Sherlock in England brought a wool blanket to the spotlight. It soon became a burst for many parents to give their children.

Apart from the design, parents are more concerned about: if it is not hand woven, and can really make the newborn skin care blankets have many factors such as comfort, safety and so on, can the process on the production line be achieved? During the "13th Five-Year" 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, accelerate the R & D and popularization of the key technologies of energy saving, emission reduction and resource recycling, and save resources and reduce pollutant emissions.

In particular, we should speed up the study of advanced technologies such as wool scouring, wool products recovery, wool no chlorine, shrinkproof, less water printing and dyeing, and zero discharge of hazardous chemicals.

1 years later, the release of a new type of ecological wool shrink proof processing technology, the key technology of continuous enzyme fast wool shrinking, can dispel the doubts of parents.

This technology can avoid the harm of chlorine to the environment and human body when it is treated by chlorination and shrink proof, and the treated wool products can give consideration to comfort and safety.

In July 6th, in Changshu, Jiangsu, sponsored by China Wool Textile Industry Association, Changshu Xinguang top top processing Co., Ltd. and Tianjin Luyuan Tian Mei Technology Co., Ltd. jointly held the 2016 Seminar on the achievement of chlorine free treatment of top wool. Experts and scholars from government, industry associations, enterprises, institutions and research institutes conducted a special discussion on this technology, and made a deep analysis of the current situation, the overall situation and the pressure of environmental protection, and judged the current situation of the wool textile industry from various angles, so as to make suggestions for the green pformation of the wool textile industry.

Zhou Lingqun, vice mayor of Changshou City government of Jiangsu, Huang Shuyuan, chairman of China Wool Textile Industry Association, Cao Guofen, Secretary of the Party committee secretary of Changshou City Town, Changshou City, vice mayor Gaoping, Chen Guoqiang, Dean of textile School of Soochow University, Yao Jinbo, Dean of Chemical Engineering School of Wuhan Textile University, Qu Jiande, general manager of Changshu Xinguang wool strip processing Co., Ltd., general manager of Tianjin Luyuan Tian Mei Technology Co., Ltd., vice president and so on.

Wu Yanwen, Deputy Secretary General of China Wool Textile Industry Association, presided over the meeting.

Huang Shuyuan said that with the world's wool textile industry pferred to China, China is currently the world's largest wool textile producing and processing country, but at the same time, it also brings pollution and a series of problems.

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 R & D and investment, and have achieved certain results.

In particular, the industrialization of the continuous processing technology of biological enzyme free chlorine free shrink wool has not only realized the economic effect of the enterprise, but also embodied the social responsibility of the industry.

When it comes to energy saving and emission reduction in the wool textile industry, Huang Shuyuan pointed out that during the "12th Five-Year" period, the wool textile industry actively carried out the "discharge standards for water pollutants in wool textile industry" and "water pollutants discharge standards for textile dyeing and finishing industry", and promoted a large number of advanced technologies for energy saving and emission reduction, such as small bath dyeing, low temperature dyeing, high-efficiency wool top washing machine, finishing and washing and shrinking machine.

The project "the key technology and industrialization of fast shrinking bio enzyme continuous wool" has been jointly undertaken by Tianjin Luyuan Tian Mei Technology Co., Ltd., Tianjin University of Technology, Changshou City Xinguang top processing Co., Ltd., Wuhan Textile University and Bazhou Binhai Orient Technology Co., Ltd.

Based on the theory of "double push method", the project has developed wool fiber modified high efficiency enzyme and activator, significantly improved the reaction efficiency of biological enzyme and wool fiber scales, developed the technology of continuous shrinking and fast shrinking of cellulase, and solved the technical problems of uniformity and stability in continuous process. The key device of enzymatic processing of wool fiber was developed, and a continuous processing line was built, and the industrialization of continuous and fast shrink proof processing of wool tops was realized for the first time, and the green processing of wool shrink proof was achieved.

The overall technology of the project has reached the international advanced level and has reached the international leading level in the continuous shrink prevention technology of wool top.

At the same time, the wool fiber produced by the project technology is of excellent performance, stable quality, advanced and mature technology, and has broad application prospects.

Yao Jinbo introduces biological enzyme continuous type.

The key technology of rapid shrinkage prevention is: "at present, the most widely used shrink prevention process is chlorination and shrinkage prevention.

This process has the advantages of low cost and good shrink proof effect, but the organic halide AOX (Absorbable Organic halogenide) produced during the treatment process will seriously pollute the environment. At the same time, the emission of AOX is restricted by legislation at home and abroad.

Moreover, its residual chlorine is difficult to clean and does not conform to the processing requirements of ecological textiles.

At present, there are many methods for preventing wool from chlorinated wool, such as Potassium Permanganate method, peroxide method, ozone gas treatment method, biological enzyme method, low temperature plasma treatment method, liquid ammonia method, and natural polymer and nano material finishing method.

Among them, biological enzyme method is not only eco-friendly, but also has mild reaction conditions, high catalytic efficiency, safety, easy operation, and easy biodegradation of waste liquid.

In the course of implementation, the rapid shrinkage control technology of biological enzyme wool has the rapid completion of scale modification, anti felting, and TM31 (585A) -8% technical requirements. At the same time, it can reduce the damage of wool fibers and the uniformity of shrinkproof treatment.

In the continuous production, the stability of working fluid and the stability and reproducibility of wool treatment quality are designed. A new processing idea, the key technology of rapid continuous shrinkage of biological enzyme, is designed.

The dyeing and spinnability of the products produced by the production process reached the level of chlorinated products of the same kind, and the anti pilling level was higher than that of similar products.

In introducing the process of chlorine free shrinkproof wool, it is said that "Luyuan Tian Mei has spent nearly 1 years working closely with Changshu Xinguang wool top company to pform the existing chlorination method to remove flake equipment, use Luyuan Tian Mei's auxiliary agent to achieve scaling effect under the original technological conditions, thus realizing the industrialization process of chlorine free shrinkproof top, and naming the process as" Eve Xin "process.

Yang Wanjun said that the next step will be to improve the rapid online monitoring technology in the production process, and promote the formulation of international standards, promote the popularization of the project, and further promote the research on reducing costs, improving production lines and comprehensive utilization of wastewater.

Jiangsu Changshu Xinguang top processing Co., Ltd. focuses on wool chemical processing for 16 years, with an annual capacity exceeding 15000 tons.

According to Qu Jiande, general manager of the company, the company has jointly produced, studied and studied three parties. After more than 1 years of factory field research and exploration of technology, a major equipment pformation was carried out, and the laboratory test technology was pformed into a continuous chlorination free process.

At present, the key technology of biological enzyme continuous wool rapid shrinkage control has the ability of mass production, and the processing technology is gradually optimized. The product ecology meets the requirements of the textile standard Oeko-Tex100, meets the requirements of post processing, anti fuzzing and pilling performance, and gloss returns to nature.

Speaking of the future of bio enzyme shrinkproof wool technology, Qu Jiande said that the next step will be to reduce costs, stabilize processes and optimize processes three aspects.

It is necessary to select more efficient and cheap chemical additives, greatly reduce production costs, further improve product quality, and integrate a set of intermediate control and monitoring methods that are suitable for industrial production, stabilize product quality, reduce raw material costs, develop special production lines, overcome difficulties, and bring bio enzyme shrink resistant wool products to market.

At present, the key technology of rapid continuous shrinking of biological enzyme has been capable of mass production.
