Us Connell Textile Scientist Invented Counterfeit Package Technology To Make Fake Bags Worthless.

U.S.A Connell Textile scientists Juan Strait (Juan Hinestroza) and his colleagues covered the surface of the package with a substance that could not be seen with the naked eye. When scanned by a magnetic instrument, you could know where the bag came from and who made it. "You can put metal nanoparticles on the bags and mark them, just like barcodes." PhD, University of Florida Ken Cournot (Dr. Ken Kuno) said so.

Scientists hope that this new identification technology can finally make fake. GUCCI (Gucci), Prada (Prada) and Fendi (Fendi) bags are worthless. The ABC correspondent stationed at the Losangeles police sub Bureau said that the profits of counterfeit products were larger than that of drugs. According to statistics from the World Customs Orgnization, 1/10 of the world's trading markets are dominated by counterfeit products, which can generate about five hundred billion dollars of revenue per year for counterfeiters.

In order to defend their brands and interests, the fashion industry has been working hard to combat all kinds of problems. Counterfeit goods But it is still difficult. West Roza hinted that the US government was also interested in his invention and hoped to apply this technology to the identification of counterfeit banknotes. But what is worrying is that once this technology is widely used, it is likely that counterfeit producers will also imitate this technology.

Professor Chen Nanliang of Donghua University opens. Aerospace textiles The world

When Chang'e three explored the moon, Tiangong-1 also greeted its successor, Tiangong two, in space. These great events of space make a textile expert. Chen Nan Liang Special care. Because Tiangong-1, No. two and the first cargo spacecraft began to build the Chinese space station, and their "wings" - solar panels are all hand woven by the Chen Nanliang team.

Surprisingly, the spacecraft's solar wing materials are fiberglass, and they are woven into semi-rigid grid materials by Chen Nanliang. Recently, he also used the gilded wire to compile the first China spaceborne netted antenna, which will also be accompanied by high-performance communications satellites next year.

Before opening the "space textiles" world, the chasing ideal people almost gave up several times.

　　 For fear of going to "gully"

Chen Nanliang is from Shanghai, after 60. Science and technology is good, and also want to be a doctor. When I was admitted to university, my parents did not satisfy his professional aspiration because he was afraid he would be assigned to work abroad. The logic of the parents is very simple: when the local doctors in Shanghai were full, they must be assigned to the field. They might go to the ravine ditch, while the textile industry is basically on the coast.

In this way, Chen Nanliang entered the predecessor of Donghua University. East China Textile Institute of Technology Knitting specialty. He admitted that he didn't know what knitted was when he entered school. In the first semester, Chen Nanliang gave up some of himself and felt that reading was boring. Until he met Professor of physics, mechanical principles and other professional courses, and learned that textile is not only clothing, bedding, curtain carpet, and so on, there is a large category: industrial textiles. Because the traditional materials in many industries can be obtained by using new fiber materials and textile methods. For example, artificial blood vessels are medical textiles. Finding the closest thing to the profession and his ideal, he began to work hard, stay in school assistants, start research, and never go back.

　　 Weave the veins from the blood vessels to the leaves

When Chen Nanliang started from the artificial blood vessel, he did not realize that the road was not easy to walk.

Chen Nanliang is a native Donghua "Ben, Shuo Bo". He has never really stayed in school. The two time, as a senior visiting scholar, did not go abroad for more than six months, and the purpose was very strong.

For the first time, he aimed at artificial blood vessels and went to the knitting Institute of Brno, Czech, specializing in vascular warp knitting technology. As we all know, textile is usually crossed by longitude and latitude, while warp knitting is made in 45 degrees or even 20 degrees. When Chen Nanliang returned from his studies, he found that the domestic textile machinery foundation was weak, and fiber materials were also lacking.

The road was blocked, but Chen Nanliang did not give up completely. After all, warp knitting technology can also weave other products. Chen Nanliang often goes to see exhibitions with foreign companies, studying all kinds of warp knitted products, including wind turbine blades made of glass fiber warp knitted fabric, which are large, light and strong, and can resist torsional damage. In order to learn wind blade weaving technology, he went to Kaiserslautern University of Germany to exchange directionally. It has the best test facilities in Europe, including a 2000 ton compressor. Chen Nanliang realized that the domestic warp knitting industry should be industrialized, so we must first introduce the textile machinery equipment, digest and absorb and innovate again. Approved by the European Union, the first warp knitting machine was settled in Changzhou through industry university research cooperation. This will allow domestic fans to grow in size and power from 0.6 MW to 1.5 MW, and now to 2 megawatts. After several years, such warp knitting machines have also been made domestically.

　　 People around are in the workshop.

"Big windmill" is flying with the wind and tenacious and durable. Chen Nanliang has finally created an enhanced textile material which is completely different from cloth. This also allows astronauts to come to us.

As soon as we enter the gate, we know that the space station system belongs to the low orbit spacecraft. Although it is close to the earth, the space environment is not good, not only the space trash is much, but also the "atomic oxygen", which makes the aluminum alloy and other metal materials easily oxidized and scrapped. The solar panels, which are widely equipped with spacecraft, are made of aluminum alloy. The use of fiberglass without oxidation can be replaced by warp knitting "energy wings", which has a lightweight and strength aluminum alloy windsurfing. High quality glass fiber, such as cotton yarn, is smooth, with a diameter of 5 microns, about 1/4 of conventional products. Although the products of this level are abroad, they will never be exported.

Space missions are like mountains, and they will be handed over in March. Those 3 months are the hottest 3 months of the year, and Chen Nanliang and others are five or six people in Changzhou factory all day. Due to years of cooperation accumulated by the warp knitting fan blades, the workshop of the factory stayed overnight for Chen Nanliang until two or three in the morning.

It was the most painful and exciting day. Chen Nanliang did not want to sleep at all, nor did he feel tired at all. As the saying goes, "how much material is given and how much cloth it is woven", when the spinning machine has just started, the first few dozen meters are often useless cloth. And this space glass fiber is so scarce that it almost drives Chen Nanliang team into a dead end. After 3 months of failure, even a PhD student was in a cold workshop without air-conditioning. But Chen Nanliang was sticking to his final success. He was not asleep the day he got the qualified samples, and he found himself overdrawn second days ago.

"Heavenly palace" finally has new "wings". The warp knitted mesh is flexible in the middle and forms a hollow structure. It not only has good heat dissipation performance, but also can generate electricity on both sides. Chen Nanliang is proud to say that Tiangong-1 has solved the problem of photoelectric energy supply and long term rail retention. Compared with the design life of 2 years, it can greatly delay the "retirement".

In the "space textile revolution", Chen Nanliang and his collaborators independently designed and manufactured special warp knitting machines. During the 3 years of research, seven or eight invention patents were obtained. Based on this research and development system, Chen Nanliang has just delivered the satellite antenna made of metal filament warp knitting to the space system, its diameter can reach 32 meters, far greater than the satellite itself. Compared with the aluminum alloy made pot lid small antenna, it is light and strong, the signal reflection area and efficiency greatly increased.

"Now it is discovered that the warp knitting world of space products seems to be infinite and can do a lot of things." Making new things out of their own hands, Chen Nanliang is closer to the dream of college than ever before.
