Character profile: Deng Zhongmin, second-level professor at Wuhan Textile University, graduate tutor, senior visiting scholar at Deakin University in Australia, academic leader in the direction of clothing design and engineering, advantageous science and characteristic fields of universities in Hubei Province (CAD in the field of textiles Application) academic leader, young and middle-aged experts with outstanding contributions in Hubei Province.
Mainly engaged in the research and development of textile and knitwear products and equipment. He has published more than 100 scientific research papers, and has presided over the completion of more than 10 provincial and ministerial level and more than 50 horizontal scientific research projects, including major projects in Hubei Province. The fully formed seamless fabric developed has various properties such as warmth and antibacterial. The results are at the leading level in the country. It has won more than 10 awards such as the second prize of Hubei Province Science and Technology Progress Award and the Hong Kong Sangma Science and Technology Award. It has been successfully used in Guangdong, Fujian, and More than a dozen cities in Shandong have applied it and achieved good social benefits.
Yesterday, Professor Deng Zhongmin of the School of Textiles of Wuhan Textile University received feedback from his colleagues that the “trousers, socks, and insoles” thermal three-piece set developed by him and his team sold well on the group buying platform. The product appraisal certificate shows that clothing made of this kind of fabric can heat the skin by 3.1-8.4°C in a short period of time after wearing it. In order to achieve this goal, Deng Zhongmin’s team has been working hard for more than seven years, and has tested more than a thousand materials.
Use “sandwich” fabric to lock in the air
After the product was developed this year, teachers in Deng Zhongmin’s team all wore it.
Team member Ke Wei wore a skirt yesterday and only had a pair of warm pants on her legs. She said that in the past, she had to wear long johns, warm pants, and outer pants to withstand the “magic attack” of Wuhan winter. Now she feels warmer. “The effect should be more obvious when the weather gets colder.”
Professor Deng said that compared with common warm clothes on the market that use fleece fabrics, theirs uses a “sandwich” structure, using two layers of fabric to sandwich the air layer, retaining more still air and achieving better results. In addition to the thermal insulation effect, each layer of fabric has a thermal insulation layer on the inside and a wear-resistant layer on the outside. The clothes are more washable, less prone to pilling, and the thermal insulation effect is longer-lasting.
In order to stabilize the air layer and prevent the air from being squeezed out, Deng Zhongmin proposed that the two layers of fabrics should be interwoven with threads to provide support, and the edges should be “locked” at any time so that the fabrics can be cut at will without breaking. affect performance.
In the process of practice, in addition to changing the process and equipment, they also changed the materials. After more than a thousand tests, Deng Zhongmin’s team selected hygroscopic and heating fibers made of cotton fiber and zirconium carbide composite powder rayon fiber and spandex fiber to weave together the upper and lower layers of fabric, which is full of elasticity; it also used polyester coffee carbon fiber to make the middle layer The intertwined threads not only help to heat up but also achieve antibacterial purposes.
Sentinels have already put on this new type of warm clothing
According to reports, some sentinels have already put on this new type of warm clothing.
“Now, we are still constantly improving the product to make it warmer, more fashionable, and meet the needs of more people.” Professor Deng said, He envisioned using environmentally friendly adhesive to composite the fabric to make it warmer, and in the future it could become an outdoor clothing fabric under extremely cold conditions for use by soldiers, outdoor workers, climbers, etc.
“Even for ordinary people, this technology is very meaningful. Think about it, maybe it can partially replace down jackets, allowing us to get rid of heavy layers of clothing in winter and travel. It’s more convenient and the image is more beautiful,” Kewei said.
The reporter learned that in addition to keeping warm, Deng Zhongmin’s team also has more research and development goals: moisture conduction, rain protection, etc., and integrating these functions into one fabric. “In recent years, the public’s demand for multifunctional textiles has increased significantly, and this type of textiles has great potential.” said Feng Jun, director of the Science and Technology Department of Wuhan Textile University.
Chen Gang, the liaison officer of Wuhan Science and Technology Bureau at Wuhan Textile University, said that by the end of 2019, the domestic leggings market had reached 350 billion yuan, and insoles, socks, etc. were worn by people every day. The research and development results of Deng Zhongmin’s team have obtained a number of patents and have great market prospects. The Wuhan Municipal Science and Technology Bureau is connecting them to promote the transformation of their implementation into Wuhan enterprises. </p
