Zhejiang Textile And Garment Vocational College And Enterprises Jointly Research And Develop New Printing And Dyeing Technology

Recently, the scientific research and innovation team led by Professor Xia Jianming, director of dyeing and Finishing Technology Research Institute of Zhejiang textile and garment vocational and technical college, won the "best solution Award" of key technology research and industrialization (key demand) project of cellulose knitted fabric grass and wood dyeing and signed with Ningbo Guangyuan Textile Co., Ltd A scientific and technological cooperation agreement with a total investment of 15 million yuan was established. Behind this is the cooperative scientific research and exploration of the University and enterprise for more than 10 years.

The winning technology of dyeing and Finishing Technology Research Institute of Zhejiang textile and clothing vocational college is closely related to people's life. Compared with chemical dyes, the advantages of plant dyes are obvious: green, environmental protection and health. However, its limitations lie in that to meet the requirements of industrial production process technology needs to form a complete technical system through scientific research, and there are problems such as less chromatography and low color fastness.

Ningbo Guangyuan Textile Co., Ltd. was established in 2007. At the beginning of its establishment, it did traditional printing and dyeing processing. With the transformation and upgrading of printing and dyeing industry, the living space of printing and dyeing enterprises with high pollution, high energy consumption and low added value is squeezed. According to Fu Hongping, chairman of the company, starting from its core advantages, the company has made a decision to extend to the upstream of the industrial chain, aiming to build a modern textile technology enterprise integrating research and development, design, production, sales and brand operation of healthy and fashionable fabrics.

Among them, Fu Hongping paid most attention to and devoted most energy to plant printing and dyeing. Since 2009, Guangyuan company has started this research jointly with Zhejiang textile and clothing vocational college and other colleges and universities.

In order to realize the industrialization of plant printing and dyeing, it is necessary to solve the core problem of technological standards.

Xia Jianming has been working in this field for more than 30 years. The problems he studied in the laboratory are also of concern to the industry.

"Plant dyeing technology is a systematic project. In the early stage, the source and selection of plant dyes include extraction of plant dyes, dyeing process, chromatographic development, color fastness, etc., and there are also problems of technical certification and popularization and application." Xia Jianming said that at every stage, we should break through many difficulties.

Guangyuan company invests about 7% of its annual sales into R & D every year. "A mature technological process is the optimal solution found through repeated demonstration with experimental data. For example, whether the plant is crushed into water and heated to extract pigment, or put the whole plant in, which is more efficient. The temperature of the water and the duration of the heating have to be explored in the laboratory He has been engaged in the R & D of Zhejiang Textile Technology Institute, and has been engaged in the research and development of straw dyeing technology team.

After more than 10 years of research, the technology of plant dyeing has gradually matured, and has nine color systems of yellow, red, blue, purple, gray, brown, coffee, black and green.

"With the industrialization technology of plant dyeing becoming more and more mature, its application scope is also more and more extensive, not only for household clothing, bed products, but also for soft clothing, medical supplies, etc., this kind of healthy and environmental protection technology can be used." Xia Jianming talked about the future with great confidence.
