Relying On Technology, Tianjin University Of Technology Allows "Dyestuff" Dyes To Help Combat Poverty.

"I didn't expect you to be so interested in clothes made of blue indigo coarse cloth. Many people ask about other styles in live broadcast. We must work hard to meet the diversified needs of customers." Not long ago, Ouyang Chuan, deputy county magistrate of the county of Buyi and Miao Autonomous Prefecture in Southwest Guizhou Province, walked into the live broadcast room to bring goods to the special agricultural products in Guizhou. Netizens were very concerned about the indigo dyeing process, and also expressed the expectation of more varieties of clothing products. As a result, under the studio, Ouyang Chuan immediately telephoned professor Gong Jixian of the school of textile science and engineering of Tianjin University of Technology. More than three years of communication between them have made it unnecessary for them to get into the subject and discuss it.

Many years ago, in order to overcome poverty, Guizhou put forward the idea of developing the national characteristics clothing industry and launched the "splendid plan". Indigo dyed cloth has a history of more than 1000 years. For the Buyi people in the Pan River Basin, the blue indigo dyeing is not only a national traditional skill, but also a part of national culture. As the first county in Buyi County, China has seen an opportunity.

As a deep poverty-stricken county, there are abundant plant resources in the county of Puhang county. A large variety of bluegrass provides abundant materials for indigo and dyeing of the local Buyi people. Bluegrass itself is plant dye, natural and pollution-free. At the same time, it is a medicinal herb with anti-inflammatory and antibacterial functions. It can meet people's requirements for healthy life by dyeing, cleaning production and green manufacturing. However, the biggest problem of the existing dyeing technology is that the color is serious and the touch becomes blue. This brings huge obstacles to the production and promotion of indigo garments.

In 2016, Guizhou's Guizhou Heng Yi Buyi Autonomous County and Guizhou Hedu Buyi dress and Craft Research Institute Co., Ltd. heard that Tianjin had a "specialized textile" University, and then came to find the clean dyeing and finishing research team of the textile science and Engineering College of Tianjin University of Technology. This has also become the starting point for the two party cooperation.

Tianjin University of Technology's 5 teachers from different professions, such as biology, chemical engineering, and so on, form the core members of the research team. They take students to visit the research area of the county in several times. I remember arriving in Guizhou for the first time, and the team and county leaders and company leaders together to find a breakthrough. "Now the clothes stained by ordinary people are so discoloration that they have been wearing this technology for so many years." During the discussion, the question of chairman He Juchun attracted everyone's attention.

Gong Jixian and his colleagues and students began to visit each household to find the answer. Until in a family, the villagers rummaged to find a child's clothes, and the hostess said, "this dress is worn by my son. My brother is walking through it. I don't know which elderly man passed it down." Gong Jixian noticed that the clothes were dyed with vegetable dyes, which, though worn, did not fade. This gave everyone the confidence to study vegetable dyes.

Whether it is "official workshops" or "big people's VATS", the main mechanism of dyeing is the same, that is, the use of natural biological phenomena. The current emphasis is to control a spontaneous and uncontrollable process, and apply modern industrial biotechnology to natural dyeing.

Gong Jixian told reporters: "the traditional blue indigo dyeing is a strict process, similar to porcelain kilns, and there are great differences in dyeing and finishing process. With the passage of time, the traditional indigo dyeing technology of Buyi Nationality has been seriously lost, and the integrity of the process has decreased, resulting in low color fastness of the indigo handmade dyed products. At the same time, the fine dyeing process is long and complex, and is not suitable for mass production. Therefore, on the basis of traditional techniques and the restoration of traditional indigo dyeing technology, we should further develop the utilization of indigo plant and the original ecological textile, so as to really continue to inherit this ancient dyeing and finishing process.

The most difficult part of research is to search for biocatalysts, a highly efficient strain. The team was stationed in the farmers of the county of Heng Heng, observing the dyeing process for more than ten days, returning the dyed indigo to the laboratory. Over the past few years, the team has learned from the traditional natural fermentation idea, and constructed a clean and efficient plant indigo bioluminescence dyeing technology through the study of the whole cell biocatalyst, biological reduction electron transfer process analysis, biological reduction process and plant indigo molecular evolution behavior analysis. Product.

At present, with the support of the government of Guizhou's buheng Buyi Autonomous County, the plant indigo dyed dyeing factory has been set up, and the enterprise has been officially put into production for less than 1 years. It directly solves the employment of 30 local people and indirectly leads to the employment of more than 200 people from the indigo plant to the tourism industry. It is estimated that the annual output value will be about 10 million yuan, and the products will be sold at home and abroad. At the same time, it has formed industrial chains including blue grass planting, indigo dye preparation, indigo dyeing, and indigo related daily chemicals, health products and other products, and has promoted the development of local industrial tourism.

Indigo dye is natural and pollution-free. It is a medicine that can be eaten by itself. It is in line with people's pursuit of healthy life. Next, we need to start developing more health products. " Speaking of this work, every member of the team is very excited because they turn their research results into economic benefits, and use technology strength to help them tackle the poverty alleviation strategy with a sense of accomplishment.
