"Transformation" And "Black Technology" Of The Textile Industry Appear In Tianjin Modern Light Textile Industry, With An Output Value Exceeding 100 Billion Yuan In The First Half Of The Year

It only takes 30 minutes to achieve sleep and wake-up by stimulating the brain, smart vests that can be "sewn" into the circuit of divers' body indicators module, carbon/carbon composite materials that can withstand 1600 degrees Celsius, thin and light arc resistant fabrics that can instantly form a thermal insulation and carbonization layer when encountering an arc... Tianjin, a city with a history of more than 100 years in the textile and clothing industry, With the help of "black technology", a new way of development is emerging.

The project of "from 0 to 1 and then to N" has been launched, and the products from silk to cloth to clothing have been shaped. The pace of laboratory and enterprise cohesion innovation has become more and more firm. Relying on group innovation, in the first half of this year, the output value of Tianjin's modern light textile industry exceeded 100 billion yuan, and the industrial transformation and upgrading are moving towards high-end and intelligent.

　　 Laboratory research and development of "Shangtianhai" new technology

At present, technical textiles with development potential and high added value have become a new economic growth point for the development of textile industry.

At the China Astronaut Research and Training Center, two EEG caps and four sets of muscle electrical stimulation clothing from the School of Textile Science and Engineering of Tianjin University of Technology (hereinafter referred to as the School of Textile) are being tested. In the future, these clothes and hats may go to the moon with astronauts.

"Astronauts should try to keep a normal biological clock during their stay in space. When they fall asleep and wake up, the EEG cap can stimulate the brain to fall asleep and wake up in only 30 minutes. In the space environment for a long time, human muscles will shrink, and muscle electrical stimulation clothing can help astronauts recover muscle function." Liu Hao, a professor of the Textile Institute, who led the project, told reporters that, EEG cap is composed of elastic fabric, integrated electrode and electrical stimulation module. "In research and development, we first solve functional problems, then solve comfort problems".

In addition to "going to heaven", small fabrics can also "go to sea". How can the clothes on the divers monitor their heart rate, blood pressure, blood oxygen and other physical indicators at the bottom of the sea hundreds of meters away? This is the research project of the Institute of Intelligent Wearable Electronic Textiles of the Textile Institute. The difficulty of this subject lies in how to better integrate electronic devices with textile clothing. "It can be simply understood that the lines of the monitoring module should be 'sewn' into the clothes. How to 'sew' is the key. At present, the integrated technology of functional clothing is mainly used to embed the flexible electrode bionic sensor into functional clothing." said the relevant person in charge of the research institute.

In recent years, in Tianjin University of Technology, this kind of high-end textile research project is "full of flowers".

"You see, this is the banana raw hemp extracted from the stem of the banana tree. The banana fiber extracted here has similar properties to hemp, with high strength, high moisture regain, fast moisture absorption and drainage, strong antibacterial property, biodegradable and other characteristics." In the laboratory of Professor Zhang Meiling of the Textile College, nearly 500g of banana fiber can be extracted from 1kg of banana stem raw materials, The blended yarn made of banana fiber and cotton fiber can be woven into bedding, curtains, sofa cloth, etc.

Tianjin University of Technology has always had strong scientific research strength and the ability to transform scientific and technological achievements in the field of modern textile. Up to now, the school has carried out nearly 1000 projects, such as research and development of electronic textiles for promoting sleep transcranial electrical stimulation and muscle rehabilitation electrical stimulation, neuromuscular stimulator, sleeve and finger sleeves for transcutaneous electrical stimulation of specific points of limbs, and has won 15 national scientific and technological awards and more than 1000 authorized patents.

　　 The implementation of industry, education and research promotes the "broken circle" of products

The laboratory of the Textile Institute has achieved "from 0 to 1", and "from 1 to N" has been handed over to the enterprises that realize the transformation of scientific and technological achievements through industry university research cooperation.

"Speaking of the high precision of the textile industry, carbon/carbon composite prefabrication technology is a good example." In Weiduowei Technology (Tianjin) Co., Ltd., Li Yu, the general manager, picked up a sample and told reporters: "This is the basic product of carbon/carbon composite prefabrication, which can weigh more than 10 grams per square meter at the lightest. The tensile strength of carbon fiber is extremely high, 7 to 9 times that of steel, but its radial strength is average, and its cohesion is poor. It is a huge challenge to comb it into a uniform and continuous wool net. " According to him, the working temperature of electronic grade polysilicon used to prepare chips in the production process is up to 1600 ℃, and the carbon/carbon composites based on carbon mesh tires can be used to make high temperature resistant furnace bodies or inner thermal insulation layers.

Many technological upgrading and product innovation are "forced". Zhao Xiaoming, the general manager of Tianjin Shenwei Flexible Protective Materials Technology Co., Ltd., is also the head of the protective textile materials innovation platform of Tianjin University of Technology.

"This is the lightest arc protection fabric in China at present," said Zhao Xiaoming, pointing to a piece of green fabric on the company's display platform. Although the surface looks like ordinary fabric, the function of this fabric has great potential.

It is reported that the instantaneous temperature of the arc can reach nearly 20000 degrees Celsius. When this material is used as the protective inner layer of the arc protective clothing, carbonization will occur at high temperatures, forming a dense carbonized layer. This carbonized layer has a low thermal conductivity, which can effectively block the heat transfer and slow down the heat transfer to the human body. At the same time, the carbonized layer can also prevent the spread of flame, play a certain role in flame retardance, and avoid burns. "Since we have independently developed and mastered key technologies and arc protection materials with the same specifications and protective effects, our price is less than half of that of foreign imports," he said.

Next to the arc protection fabric, an inconspicuous white cloth attracted the attention of the reporter. "Some scientific explorers and sailors will get eczema if they cannot change their clothes in a humid environment for a long time. This cloth can solve this problem." Zhao Xiaoming said that this seemingly ordinary white cloth has an antibacterial effect that reaches the international advanced level. After 50 times of washing, the antibacterial rate of general antibacterial cloth may still be more than 70%, while after 150 times of washing, the antibacterial rate of this cloth can still reach more than 90%.

"What is this' leather '?" A piece of "leather" on the table looked "incompatible" with other fabrics. "This is the fabric of medical radiation protective clothing. It is lead-free and non-toxic, and can replace traditional lead clothing. Under the same protective effect, its weight is 30% lighter than that of traditional lead clothing." Zhao Xiaoming told reporters that the project took six years from research and development to landing, and has now been industrialized in a Beijing enterprise. Its X-ray protective clothing The radiation shielding curtain and other products have been applied to Beijing Friendship Hospital, General Hospital of the Chinese People's Liberation Army, Fuwai Hospital of the Chinese Academy of Medical Sciences, Peking Union Medical College Hospital, etc.

In recent years, Tianjin textile enterprises and scientific research institutes have promoted the transformation and upgrading of the industry to the intelligent and high-end direction by focusing on collaborative innovation in the research, development and application of new textile materials, production processes, intelligent manufacturing and other aspects. 26 projects, such as cotton copper ammonia polyester cross warp strong twist fabric and multi-functional bamboo series developed by Tianjin Tianfang Investment Holding Co., Ltd., have reached the leading level in China; Tianfangbiao Testing&Certification Co., Ltd. has formed a number of core technologies and products, such as broken prototype, corrosion-resistant water bath shaker, near-infrared nondestructive testing model, soaping automatic dispenser, and has led China's textile testing industry to reach the international leading level in specific fields. The project research achievements have filled a number of gaps at home and abroad.

Moreover, there are many technological innovations in Tianjin's textile industry. In the opinion of Ma Bojun, Secretary General of Tianjin Garment Chamber of Commerce, Tianjin's textile industry has a solid foundation, with more than 100 high-quality enterprises such as Tianjin Textile Group, Lingzhi (Tianjin) Garments, Phoenix Contact, etc. New products, new technologies, and new "smart manufacturing" bring new opportunities to enterprises and industry development. "In recent years, Tianjin's textile industry is accelerating to improve its' quality 'to' new '. More and more enterprises are strengthening research and development to improve the scientific and technological content of products and services and increase the added value of enterprise transformation," she said.

Reporter's notes

Those scenes outside the report

The textile industry is "going up"

"You should go to the workshops of those old textile factories again, where the foundation of industrial development and the strength of scientific research and development are hidden. Our textile industry is on the way to a higher level." As the interview drew to a close, Liu Yong, executive vice president of the School of Textile Science and Engineering of Tianjin University of Technology, suggested to the reporter.

Once, the traditional textile industry was labeled as "labor-intensive, high energy consumption, low added value". Now, a new round of scientific and technological change is sweeping the world, and Tianjin's textile industry is quietly "transforming" in a busy world.

Tianjin Jinying Spinning Co., Ltd., which has built a factory for more than 30 years, has an annual output of nearly 7000 tons of sewing thread, and has maintained many years of cooperation with famous enterprises such as Li Ning, Anta, Bosideng, etc. Last year, the factory invested more than 20 million yuan in digital transformation.

Before manual doffing, one person repeated 4000 times a day, and 10 people completed 3 tons of production in 12 hours. Now automatic doffing, 2 people can complete the same workload in the same time; In the past, when the yarn of the manual connector was broken, it was necessary to check each spindle one by one. A worker could see seven or eight spinning wheels at most. Now 20000 spindles are equipped with single spindle monitoring equipment. Once the wire is broken, we can immediately know which spindle is in trouble. The whole workshop only needs two people to watch the spinning wheel.

In Tianjin Dayang Intelligent Manufacturing Co., Ltd., a piece of drawing is input into the computer, and the plate making and printing machine can automatically cut out clothes samples. Previously, manual cutting took more than half an hour, but now it only takes more than 10 minutes.

The equipment is advanced, the efficiency is improved, and the market is opened. Up to now, the school uniforms produced by the company have been shortlisted in 11 schools in 5 districts of our city, with 30000 sets of work clothes and 10000 sets of professional clothes delivered. In the first half of this year, the sales reached more than 63 million yuan.

Tianjin Phoenix Industrial Development Co., Ltd. designs and produces nearly one hundred wedding mother's clothes every year, with hundreds of fabrics and tens of thousands of accessories. How to quickly find a button and thread among thousands of accessories? The answer is hidden in the warehouse.

In the auxiliary material area of the warehouse, thousands of drawer shaped boxes in the stereo warehouse are attached with RFID (radio frequency identification) intelligent tags. Input the code on the handheld device, and you can know the specific location of the auxiliary materials immediately, which greatly improves the efficiency of warehouse management. Now, the factory can make hundreds of wedding mother clothes every day, and sold tens of thousands of them last year.

One by one, the laboratories lead the country in "black technology", and the production lines are set up with groups of "intelligent manufacturing" scenes. Traditional textiles are no longer "traditional". More and more textile enterprises actively introduce and promote the use of digital technology, accelerate the transformation and upgrading of intelligent factories and digital workshops, and continue to innovate in key processes, fabric technology, etc. The textile industry is changing from labor-intensive to technology intensive.

Expert opinion

Achievement transformation "from 1 to N"

Focus on enterprise innovation

　　 ——Interview with Liu Yong, Executive Vice President of School of Textile Science and Engineering, Tianjin University of Technology

Why are the scientific research achievements of many universities locked in the drawer? Asymmetric information, lack of pilot test scenarios... There are many reasons, how to break the point?

"From 0 to 1 depends on colleges and universities, and from 1 to N depends on enterprises to activate the 'power source' of innovation. The textile industry is no longer a labor-intensive 'sunset industry', but a high-tech, green and fashionable industry with high added value," said Liu Yong, executive vice president of the School of Textile Science and Engineering of Tianjin University of Technology.

Innovation is the first driving force leading the high-quality development of the industry. Tianjin's textile and clothing industry has experienced a high light period in history, but in recent years, with the transformation and upgrading of the industry and the booming development of textile and clothing industry in other provinces and cities across the country, Tianjin has gradually been overtaken. For a time, the textile industry was considered as a "sunset industry" with large pollution, small profits and gloomy prospects.

In Liu Yong's opinion, there is no backward industry, only backward products and technology. Tianjin textile and clothing industry has a good industrial foundation, with core technology enterprises such as Tianfangbiao Testing and Certification Co., Ltd., Tianjin Needle Research Technology Co., Ltd., as well as scientific and technological research and development platforms such as the State Key Laboratory of Separation Membrane and Membrane Process of Tianjin University of Technology, the Key Laboratory of Advanced Textile Composite Materials of the Ministry of Education, as well as Tianjin University of Technology, Tianjin University of Science and Technology Tianjin Academy of Fine Arts and other well-known institutions in the industry provide a stable innovation ecosystem for industrial development.

"Industrial development is afraid of 'the old has gone, the new has not come'. Enterprise innovation is the key to the landing of scientific research achievements and the transformation and upgrading of the industry to intelligent and high-end." He said that the transformation of cutting-edge scientific research achievements needs the support of advanced technology and intelligent production processes of enterprises. To develop the textile industry, it is necessary to continue to unblock the development channels of industry university research integration, strengthen the cooperation between enterprises, universities and scientific research institutions, give play to the leading role of leading enterprises in cooperation, and boost the industrial development into the fast lane.
