Materials That Keep You Warm Under The Spotlight At The Beijing Winter Olympics

Do you know about materials that keep youwarm? Recently, our reporter learned that a new material developed by Professor Wang Dong's team at Wuhan Textile University has provided a warm "innercore" for the winter Olympic and Paralympic security clothing for theBeijing 2022 Winter Olympics and Winter Paralympic Games. The secret of how tomake the winter Olympic and Paralympic security guards wear warm clothes in thecold winter outdoors is hidden in a new material of "multiple functionalpolyester staple fiber". The warm core of the cold-weather clothing 70% ofthe new material, and other fibers mixed into the warm wadding, with instantwarming, long-lasting heat storage, thin and comfortable, sweat-absorbing andbreathable performance. Scientists are studying materials that keep you warm.

New materials to do the "core"of the cold-proof clothing

It looks like an ordinary gray flocculent,but when you touch it and rub it, it immediately heats up, and in theexhibition hall of "interdisciplinary research team based on fibermaterials" on the 4th floor of Wuhan Textile University Institute ofTechnology, our reporter saw this "multiple functional polyester staplefiber "new material.

"This is Sinopec in a few years ago totake the initiative to find us for targeted research, the team only spent halfa year to do it, the technology transferred to Sinopec." Wang Dong,professor of Wuhan Textile University and director of the Key Laboratory ofTextile Fibers and Products of the Ministry of Education, introduced this newmaterial to do the "inner core" of the cold-proof clothing, which canquickly and as far as possible absorb the perceived light, through theefficient transformation of light energy into heat energy, and then slowlyrelease the heat. Some scientific experiments on materials that keep you warmare being conducted now.

After the rapid completion of technicalresearch, Sinopec to find downstream producers "Yizheng ChemicalFiber" for mass production, the first batch of 300 tons immediately soldout, Wang Dong said, not only good performance, 1 ton of raw material profitmargin than conventional polyester 21 times higher, bringing actual economicbenefits.

"When it comes to textiles, peopletend to equate clothing with it, which is actually a misunderstanding of thetextile industry." Wang Dong introduced, textile materials are essentiallya basic material that can be applied in various fields.

Functional fiber polymers and fibers,nanofiber filtration membranes, wearable electronic flexible devices,biomedical ...... Wang Dong's team's scientific research application productsare getting richer and richer, and the transformation efficiency is greatlyimproved, forming a good cooperation with enterprises such as Sinopec andDaikin of Japan, which will initiate the scientific research transformationwith Wang Dong's team every year in a targeted manner.

"To do what others can't do

In the door of the "InterdisciplinaryResearch Team based on Fiber Materials" on the 4th floor of the Instituteof Technology of Wuhan Textile University, the slogan "FourOrientations" is posted. Wang Dong said that scientists should begoal-oriented, demand-oriented, application-oriented, so this is posted at thedoor, "I want to show every teacher, every student, to engage inscientific research in the end for what. As scientists, we have to shoulder ourhistorical responsibility and keep marching into the breadth and depth ofscience and technology." Some scientific progress has been made inmaterials that keep you warm.

In 2005, when Wang Dong was studying in theUnited States, he discovered a special phenomenon in one of his experiments andthought of using this phenomenon to make original scientific achievements andsolve the international problem of the difficulty of mass production of polymernanofiber materials. Since then, Wang has been devoted to the industrializationof nanofiber materials and their application in precision filtration materials.

"Do science and technology that otherscan't do and make up for the shortcomings of the supply chain." Afterreturning from the United States to teach at Wuhan Textile University, WangDong has been doing market-oriented transformation of scientific andtechnological achievements. With the scientific research goal ofmicro-nanization, functionalization and high-performance of fiber materials, hecuts into the pain points and difficulties of various industries, and usesfiber-related technical means to meet the demand.

He has cooperated with orthopedic hospitalsto make high-performance polymer materials PEEK, and his newly developedfunctional fibers for heat and humidity control are immediately seen by manyenterprises. ...... Starting from nanofibers that are 1000 times thinner thanhair, Wang Dong now leads the "interdisciplinary research team based onfiber materials "towards a broader red sea of applications.
