Study On The Bio Degumming Of Hemp Fibers By Donghua Students' "Cross Boundary"

< p > when it comes to hemp, people often think of the functions of air permeability and moisture conduction.

At Donghua University, there is a student centered research team on biological degumming of hemp fibers. They actively carry out scientific and technological collaborative innovation in an interdisciplinary and cross disciplinary manner. They include not only the first prize of national college students' extracurricular academic competition, but also the heavyweight award of the national college student entrepreneurship program, and the Xiaoping science and technology innovation team selected by the Central Committee.

< p > it is understood that the commonly used degumming methods in the textile industry are chemical methods, that is, strong acid, strong alkali and strong oxidants are used to treat raw hemp. This is not only energy consuming and high cost, but also can not recycle waste water, and pollution is a big problem.

How to make bast fiber green and green? "With a doubt, under the guidance of teachers such as Yu Chongwen, Zhang Xingqun, Yang Jianping and Chen Ting, the research team has been drilling into the research world of hemp fiber biological degumming in 2008.

< p > according to the team leader and Dr. Ding Ruoyao of the 09 grade Textile Institute, the biological degumming originated from the "retting". In a popular way, it is to put the linen in the pool for several months, and to promote the fermentation of the bacteria inside it, so that the bacteria can eat the gum on the linen.

"This practice has a long cycle and a high labor cost, and we need to find the most suitable strain of" a href= "//www.sjfzxm.com/news/index_c.asp" hemp fiber < /a > biological degumming and cultivate it in large quantities to improve the speed and quality of degumming.

For P, Ding Ruoyao and other members went to the factory for a few months, unable to attend to the harsh environment of high temperature and high humidity in the workshop and the unpleasant smell of chemical smell.

Ding Ruoyao said: "at three or four in the middle of the night, it is common practice to get up and see the experiment process."

< p > in order to promote technology < a href= "//www.sjfzxm.com/news/index_c.asp" > industrialization < /a >, the team worked with a Ma industry enterprise in Yuanjiang, Hunan, from laboratory small test to pilot plant test, and finally realized industrial production.

This technology not only helps enterprises to reduce unit energy consumption greatly, but also saves production costs. Moreover, the total amount of pollutants discharged has also been greatly reduced, which has achieved good social and economic benefits and environmental benefits.

< p > at present, more and more colleges and universities advocate "collaborative innovation", < a href= "//www.sjfzxm.com/news/index_c.asp" > Ding "/a", they write Donghua students' understanding and interpretation of these four words in action.

In this "student army" consisting of 4 doctorates, 7 masters and 4 undergraduate students, there are both students who study textile engineering, students who learn biological engineering, and students who learn chemistry.

Zhang Yixiang, 12 master of chemical biology, said: "the biggest advantage of interdisciplinary and cross boundary research is to broaden our horizons and inspire creativity through collisions with other professional students.

He talked about how high temperature, choice of bacteria and proportion of bacteria should be used for degumming of hemp fibers. These are established step by step in the course of continuous discussion and discussion. "The whole study is by no means a professional student, and interdisciplinary and interdisciplinary is a must."

Ding took an example. At the very beginning, they used pure biological methods to retting hemp fibers, but the effect was not satisfactory. Later, thanks to the students in chemistry, they woke up and suggested that after adding a small amount of chemical reagents, the degumming effect had been significantly improved.

He said with emotion, "there are really many sweeteners in synergy and innovation."

< p > 10 more than the national and provincial ministerial awards, 15 independent intellectual property rights authorized national invention patents, and more than 20 articles published in important publications at home and abroad. Although the harvest has been fruitful, the research team of the hemp fiber degumming research team is still unremitting efforts.
