July 6, 2016, from China

The 2016 annual Textile Innovation Conference organized by the Federation of industry is held in Shishi, Fujian.

Yu Jianyong, academician of the Chinese Academy of engineering, delivered a keynote speech at the conference on "modern textile technology innovation and development".

The contents are as follows:

It is a great pleasure to participate in the China Textile Innovation annual meeting in the famous Textile City lion, and have the opportunity to share with you some personal ideas about textile innovation.

My topic is the innovative development of textile science and technology.

We are going to talk about three aspects: first, consider the development strategy of textile industry.

Second,

Development of material science and technology innovation.

Third, we should focus on the innovation of terminal applications and improve the effective supply.

First, the development strategy of science and technology in textile industry.

Three points are emphasized here. One is to grasp the inherent law of the development of the textile industry, that is, innovation is the core link closely linked to the development of the industry.

Second, we must grasp the main trend of scientific and technological innovation in textile industry.

Third, we should grasp some key points in textile industry's technological innovation.

Textile industry innovation, as a core special system, is mainly embodied in two aspects. One is the development of the textile industry as the basic sector of human basic life and data production, and the status of the industry is very clear.

At the same time, the textile industry is also a time-varying feature, from machine textile to synthetic textile to the high-tech textile industry.

To sum up, we say that textile is a basic and eternal industry, not a sunset industry.

Microscopically speaking, the operation and technology of enterprises

Innovation, application mode innovation, if not keep pace with the changes of the times, is the sunset industry.

So I want to conclude that the core is how to innovate to promote our development.

Specifically, innovation is nothing more than two aspects: one is the demand side, the key to solve the major problems in this era. One is the sustainable utilization of resources, the other is the sustainable development of the environment, and the third is the improvement of human's quality of life and the development of activities.

It gives the textile industry new content.

Can the times make effective basic preparations for such effective demands?

Now high-tech technology endows innovation demand with sufficient technical support and supply basis.

Second, grasp the trend of scientific and technological innovation in textile industry.

There are three problems: first, grasp the characteristics of technological innovation in textile industry.

Our innovation is to promote the innovation and development of the entire industry on the basis of the worldwide technological revolution and industrial pformation.

In such an environment, our innovation is embodied in the integration of emerging technology and textile manufacturing requirements with respect to technological means.

How does the technology of textile technology and processing technology and new technology overlap?

This is an important feature of innovation.

Two, what does innovation do? Where do innovations start? What I think is the second is to grasp the theme of innovation and how we can achieve effective innovation. This is divided into several groups. I have eight thematic words, the first is the new realm. Through the development of new technologies, the performance of our products has made the technological level of our processing achieve a new level of efficiency and cost control.

The second is high quality, diversification, and development of many varieties. We develop high efficiency and low cost around high quality and multi varieties.

This is an effective way to upgrade our industry.

The third is that we represent green manufacturing and intelligent manufacturing. This is the problem of sustainable development. From our manufacturing process, raw material use and so on, we are advancing the system, reflecting the requirement of green manufacturing, we will have great room for development.

This is intelligent manufacturing. We are talking about this innovation. For the manufacturing industry, there are mainly three aspects. Intelligent manufacturing is mainly to solve efficiency, solve its quality, and solve its rapid response to the needs. This is a very important way.

Our quality and varieties need another leg to join.

The fourth key word is the consumer centered, customer centered, so that the manufacturing category reflects the needs of consumers.

At the same time, we integrate our products into multiple values, cultural elements and so on to enhance our overall value.

Third, we must grasp the overall development trend of the industry, and we will form a main line of the whole innovation system.

From raw materials to products, two support, high-end equipment and information technology, under the support of our manufacturing system.

Around these product nodes, these innovative topics have just been launched, for example, in our production, we mainly solve the problem of ecological efficiency from the processing end, from the product end, now we are focusing on solving the two major performance, one is the performance, the other is from the variety development.

In our manufacturing and processing field, we need to make overall improvement in our yarn manufacturing, weaving, weaving, and overall technology, so as to achieve high efficiency, low consumption and green processing on the basis of overall processing.

In terms of products, we need to improve the quality, how to realize the ecology in processing, this is our energy consumption is low, our resources consumption is low, the pollution is less, we must realize the resource utilization.

Fuel and auxiliaries, two major issues of green safety.

This is a great space for promoting our innovation in an all-round way and has unlimited value.

In the world of products, multi-function China, manufacturing digitalization, intellectualization, application individuation and networking form the overall layout.

In our raw materials, processing technology, especially in the application level, how to apply some systematic innovation work should be promoted.

In the field of equipment technology, our chemical fiber is mainly refined, large capacity, textile equipment to achieve high speed, high quality, automation, continuous Hua.

Dyeing and finishing equipment should be water-saving, energy saving and environmental protection on the ecological processing. How to improve the intellectualization of optical mechanical and electrical integration in the overall equipment? In our textile information field, we should integrate, modularize and intelligentize the design and manufacture. We should control the whole process in an international way. In the marketing end of the whole product, we need the Internet of things, and the large intelligent system of cloud computing improves the efficiency of our overall operation.

We think it is very important to grasp the development focus of our overall scientific and technological innovation. I think our strategic needs are embodied in five aspects: the first is the high-end, the second is diversification, and the diversified development needs to adapt to consumer demand.

The third is to expand to new high technology.

The fourth is to make our industry conform to the requirements of ecological development.

The fifth reform and opening up from the introduction of digestion and absorption to a new stage, we now simply rely on the introduction of technology this development mode is difficult to continue, we have been in some areas in textile processing has reached the world's advanced level, then our frontier technology to independent innovation to further increase, so in this, we must continue to explore.

In the overall development area, we must grasp the key points. We should break through the key technology of high performance fiber preparation and fiber utilization in new fiber materials, and improve the advanced textile processing technology mainly on the yarn.

In the field of ecological dyeing and finishing, in terms of high quality, ecological processing, chemicals, and the entire ecological chain, in modern clothing, we are mainly in functional clothing, in digital manufacturing, in the technology of sustainable technology common technology is textile materials, in the field of application, pay attention to safety aspects and so on to fully realize the expansion of the industrial chain.

In our equipment, our technology, CNC technology and other key technologies should be comprehensively upgraded.

How to improve the intellectualization in information technology?

On the second hand, we choose one point from the innovation of textile system as the overall innovation of raw materials. We have five key trends: the first is high performance.

High fiber has the characteristics of light weight, high strength, high simulation, impact resistance and high temperature resistance. It has wide application in various fields and high performance product applications.

We grasp the high-performance fiber is actually forming three groups, we are carbon fiber, carbon fiber should be said that its application is very extensive, but in its application, there are two areas are problems, the first is its brittleness, when using flexible materials, its brittleness hinders its application, the second is its performance.

The second direction is functional, which is also widely used in product development. We need to grasp what the source of this function is, that is, the constant evolution of our human life and the continuous evolution of our lifestyle. We need to rise from simple clothing function to comfort, further listing to health care, protection in some specific occasions, and further our lifestyle to sport leisure, fast-paced life. We must pursue the function of conservation, and expand the life, such as biological applications, which provide our supplementary therapy and other fields.

At the same time, the method of making functional fiber group is also diversified, with copolymerization modification.

Through the realization of the function, we can achieve different monomer copolymerization.

Third blending modification technologies.

How can we achieve the sustainable development of biomass fiber through theoretical basic research?

In this area, for example, the use of genetic engineering to achieve genetic manipulation of raw fiber is the development of silkworm mulberry silk.

The upgrading of raw materials has been realized in the whole biological engineering.

The second is regeneration, which contains cellulose and fiber production technology. We make full use of the existing cellulose resources, including some special resources.

Another is the regeneration of protein fiber, how to develop one hundred percent pure protein regeneration, we imitate the biological process of layer silk to achieve protein fiber regeneration.

Another is marine biomass fiber, marine biomass has good characteristics and biological activity, such as sodium alginate radiation protection function.

Another type is polyester fiber. How to achieve biologic technology is very important in the future.

Its bioconversion is polyester derived from biomass slowly forming biomass.

Fourth, how to achieve circular biochemistry.

In fact, we have made contributions to the feed processing industry. Our textile industry is a long way to go and solves the problem of quality of physical law, which can not be reused many times, and the cost is relatively high.

Now another way is to divide the physical method. We partially degrade, and some of them become monomers. By embedding and linking, we can develop functional regenerated fibers. This will have great prospects in the future.

The fifth is nanofibers.

Nanofibers have great applications in environment and medical treatment.

The first is the regulation of nanofiber structure, the dimension of flexible ceramic fibers.

The second is two-dimensional nano cobweb.

For example, a three-dimensional structure can also be formed.

The third part is about the application of technological innovation in textile products.

I have seen the theme of the conference. We have many women's men's wear in sportswear.

I would like to focus on two issues: fiber materials, multi-element applications and innovative applications of fiber materials.

In terms of our civilian products, our daily necessities, how do we make technological innovations? Fiber materials have become a very important engineering material, and have important applications in the fields of national defense, aerospace and aviation, especially aviation. We know that our fiber materials have become an important symbol of aircraft level.

In the field of energy, wind power, especially our batteries, batteries used for consumption, are now used in most of the materials of electric vehicles and power batteries.

Many of our environmental engineering materials used in our filtration function are fiber materials.

And our resources. Most of the recycling of water resources is mostly fiber materials.

Fiber is also a technical material for public pport systems, whether traditional cars or new energy vehicles.

For example, in industrial components, we need to enhance their dynamic characteristics. We need to use such lightweight materials, such as new buildings and building walls, which have become a basic material in the public pport system.

In addition, it is yarn, one is multi component yarn, the second is new structure yarn, and also is the yarn of chemical fiber silk.

Then there is the product, one is the embodiment of texture, one is the embodiment of function, the other is the fashion element.

I think a very important point in this is the life form.

For example, the types of sports are very large, and the development of sports fabrics is more and more different from ordinary fabrics.

Finally, the new realm of product development, namely smart wearable, smart wearable actually involves the wearable energy, one is solar energy, the other is the machinery of human movement, and the other is the corresponding chemical fiber.

How to achieve flexibility?

We use the large flexibility of textiles to make sensing machines.

The third is integrated technology.

And more importantly, creative design, how to link up with life, develop corresponding sensing, reduce the impact on the knee.
