Original Plan To Make The Waste Textiles Beautiful And Regenerate

With the improvement of people's living standard and the change of consumption mode, clothes have changed from "not enough wear" to "endless wear". It is estimated that by 2020, the total reserves of waste textiles can reach nearly 2 billion tons, while the capacity of regenerated spinning will be only 10 million tons.

How can we dig deep into the "rich ore" of textiles and let waste textiles turn waste into treasure? Wang Huaping, vice president of the Research Institute of Donghua University, presented the "China plan". He participated in the twenty-first China International Industrial Expo with the project "integrated technology of waste polyester high efficiency regeneration and fiber preparation industrialization", and won the two prize of national science and technology progress in 2018.

Using high-tech to "awaken" 2 billion tons of waste textiles

According to the China Federation of textile industry, if China's waste textiles can be recycled, it can save 24 million tons of crude oil and reduce 80 million tons of carbon dioxide emissions annually, saving nearly 1/3 of the cotton planting area. However, there are several large mountains that need to be crossed before the recycling of waste textiles. For consumers, textile recycling is often equated with "black hearted cotton". Is there really a market for new clothes? For enterprises, how to realize large-scale industrialization on the basis of cost and quality of waste textiles from different sources, colors and textures?

Turning waste into treasure requires technology to lead. As early as 2004, Wang Huaping focused on the "treasure" of waste textiles. Over the past ten years, Wang Huaping has led the research team to "drill" with the spirit of Yu Gong Shan Shan. As the main technology leader, Wang Huaping is involved in launching the technological innovation alliance of China's chemical fiber recycling and recycling, bio based fiber and biochemical raw materials, and promoting the construction of the industry standardization system. If consumers have misunderstandings, they will tackle the problem in a down-to-earth manner and strictly control the "safety clearance" of recycled textiles. In addition, the technical problems of regenerated fiber stability, conditioning, viscosity modification, regeneration, color change and color difference control have been solved one after another. Wang Huaping told reporters with the bottom of his heart: "technically speaking, China's recycled fiber technology has already been in the leading position in the world." the physical and chemical method of polyester textile, which was first created by the project, has achieved efficient regeneration from fiber to fiber. The cost of regenerated polyester has been reduced by 25%, and its performance is comparable to that of the original polyester.

From laboratory to workshop, this road is long, short and short, and how to really fall to the ground after the core technology of waste polyester regeneration has been broken down, so that the waste polyester production line of the enterprise has become "the top priority of Wang Huaping's scientific research team". He has set his sights on the enterprises in the Yangtze River Delta region. "Yangtze River Delta integration has become a national strategy. As a university researcher, we hope to promote the integration of scientific and technological innovation through the cooperation between schools and enterprises, and to achieve the" last mile "from the university laboratory to the enterprise workshop.

After tackling the technical difficulties, Wang Huaping, as the head of project technology, combined with Ningbo Dafa Chemical Fiber Co., Ltd., Jiaxing Haiyan Haili environmental protection Fiber Co., Ltd., Jiangsu excellent color environmental protection resources Polytron Technologies Inc and other enterprises, school enterprise cooperation and research together. Chen Ye is the backbone of Post-80's young teachers in the scientific research team. He commented on his mentor Wang Huaping. "Teacher Wang is absolutely the most understanding of the needs of enterprises in the field of engineering and technology, and the field of science is the most engineering application." Chen Ye said that running factories and visiting enterprises with Mr. Wang has become a required course in his work. Teacher Wang often warned him to think and solve problems from the perspective of an enterprise. He had to write papers and process sheets, and familiar with every process in the production process as an engineer. It is such a high standard and strict requirement that the scientific research team led by Wang Huaping can respond quickly to the problems encountered in the enterprise engineering application, and make the best effort to create economic and social benefits.

Today, the project has built the world's largest regenerated polyester fiber production base, producing 300 thousand tons of waste spinning regenerated staple fiber, 150 thousand tons of flask and regenerated filament, and 75 thousand tons of low melting point / regenerated polyester staple fiber annually. In the past three years, the unit has achieved sales of 7 billion 990 million yuan and exports of foreign exchange by US $261 million. Authorized 38 invention patents, published 10 scientific papers and 3 standard sets, achieved efficient recycling and high value utilization of waste polyester textiles in China, greatly improved the technical level of polyester regenerated fiber, and enhanced the image and status of China's textile recycling economy.

It is understood that with the deepening of school enterprise cooperation, the application field of recycled polyester is also expanding. Cutting-edge technology has made the once unremarkable waste textiles "beautiful regeneration" not only widely used in automobile interior decoration, environmental protection clothing and other fields, but also has been applied in many fields such as sea crossing bridges, water conservancy dams, expressways, buildings and so on, with the advantages of high fiber strength, good color fastness and stable quality. Recycled polyester is no longer a substitute for low-end textiles. Instead, it achieves "bend overtaking" and "waste", and really leverages the recycling market of 100 billion yuan textiles.

National demand is the "baton" of scientific research.

In the field of fiber research, from 2006 to now, Wang Huaping has won 5 national scientific and technological progress two prize. When asked about the secrets of winning prizes, Miss Wang gave such an answer: "to do different things in different stages, the state needs is the scientific research baton." This is the inheritance of the spirit of "high-speed spinning" of Donghua University, and also the persistence of our fiber discipline.

In 90s, functional and comfortable high-grade fabrics were imported. Wang Huaping led the team to develop thermoplastic polymer based nano composite functional fiber forming technology and key technology for preparation of high moisture conductive polyester fiber and products, which not only realized the self-sufficiency of functional fibers, but also exported to other countries all over the world. Entering the new century, Wang Huaping directed the development of super fine polyester filament, tackled technology and production problems, and displayed the Chinese fiber level to the world with high quality super fine denier yarn. Nowadays, as the environment becomes more and more serious, China is the biggest textile producer and consumer country in the world. The problem is that Wang Huaping breaks through the efficient regeneration technology of waste polyester, and provides a Chinese plan for solving the resource and environmental problems of fiber technology innovation.

Wang Huaping said frankly that each award has been paid by the team for more than ten years. He often told members of the team that he should have a sense of "national team", what the national demand is and what we can do, so that we can maintain a sober scientific research mind.
