In July 7th, the Ministry of industry and information technology published the guide for the development of key common technologies (2011), involving 8 key generic technologies in the textile industry.

Such as imitation cotton polyester fiber and its textile industrialization technology, high and new technology fiber technology, high temperature filtration material technology, high efficiency ultrafine filtration nanofiber membrane bulk manufacturing key technology, new type of biomass fiber key technology and so on.

These key generic technologies have great and far-reaching significance for the textile industry to achieve the goal of sustainable development and build a textile power.

Achieving the goal of textile power

The upcoming textile development plan 12th Five-Year will outline the textile industry of China in the next 5 or 10 years.

Blueprint for development

。

Among them, we have focused on breaking through the major technical bottlenecks restricting the development of the industry, tackling a number of common key technologies, and improving core technology and independent innovation capability.

In 2020, to achieve a strong textile country, we must have independent innovation of high-performance fiber products, and achieve industrial mass production.

These common key technologies represent the technological strength of a country.

The development of science and technology is inseparable from the participation of high performance fiber materials.

Carbon fiber, para aramid fiber, high strength and high modulus polyethylene fiber and so on are the new high-tech fiber technologies highlighted in this published guide to the development of key common technologies of industry (2011).

The high performance composite fibers such as spacecrafts, large aircraft, high-speed railways and new energy sources are indispensable.

After several years' efforts, China's carbon fiber industry is forming an industrial scale. The technology of carbon fiber precursor, pre oxidized wire and carbonization has matured, and the key equipment such as pre oxidation furnace and large carbonization furnace has been able to produce independently.

Kiloton carbon fiber equipment and carbon fiber tow (1 ~ 6K) have been mass produced; the technology of high strength and high modulus series such as carbon fiber T700 and T800 has been expanded; the technology of 1000 tons of aramid fiber is constantly improving; the aramid fiber has achieved industrial production, and its total output has exceeded 10000 tons; the high strength and high modulus polyethylene fiber varieties have increased and the output has been expanded, so that industrialization has been realized.

Some high-tech private enterprises in China seize the opportunity to adjust the national industrial policy and push forward to the high-performance fiber field.

Some powerful state-owned large companies have also increased their investment in science and technology. They have played the main role of the national team and marched into the high-tech fiber field.

It is foreseeable that the industrialization and investment scale of high performance fibers will further expand in China, and a new textile industry growth stage is taking shape.

According to the reporter, in order to cooperate with the development of China's large aircraft C919, a domestic private enterprise has successfully developed the steering wheel compound fiber product, and has passed the appraisal and evaluation of the relevant departments, and all the indexes meet the design requirements, which can meet the production needs of some key components of large aircraft in China.

Development and harmonious coexistence

The shortage of resources, the expansion of population and the change of environment require that a country's economic development should take into account the global interests.

Changing the way of growth, focusing on the future, grasping the development trend of textile technology in the world, deploying basic theoretical research and cutting-edge technology in advance, and laying a solid foundation for the future development of the industry become the consensus of the industry.

The development of the textile industry has always depended on resources such as cotton, mulberry, oil and so on. However, the limited resources make the development of the industry encounter bottlenecks, and the original situation is no longer possible.

As a result, textile raw materials have been expanded to other fields, such as marine fiber (seaweed fiber, chitin fiber), raw materials (bamboo fiber, coconut shell fiber, sugarcane fiber).

In addition, energy conservation, environmental protection and environmental protection are becoming the key to the sustainable development of textile industry.

As a result, the key technologies for mass production of highly efficient ultrafine filtration nanofiber membranes for seawater desalination, high temperature filtration materials for high temperature filtration materials for thermal power plants, and key technologies for new biomass fibers have been pushed to the front desk.

Tianjin University of Technology has been developing many kinds of membrane materials such as hollow fiber membrane materials for many years.

After the Wenchuan earthquake, the equipment for filtering polluted water was provided to the disaster area, and seawater desalination by reverse osmosis membrane technology. From the treatment of urban sewage to the provision of double membrane seawater desalination facilities for Singapore, the University made outstanding contributions to the development of the textile industry.

High temperature filtration materials play an important role in filtering harmful particulate pollutants in thermal power plants, because at temperatures of 200 degrees Celsius, the fibers in filter bags must use high temperature resistant materials, such as polyphenylene sulfide, polyimide, polytetrafluoroethylene and other fibers.

But for a time, our country could not produce and import itself.

Now this situation has changed greatly.

Sichuan, Jiangsu and other companies have made breakthroughs in the production of high-temperature filter bags.

Jiangsu Ruitai Technology Co., Ltd. has realized the industrialization production of polyphenylene sulfide (PPS) staple fiber, producing 10000 tons of PPS staple fiber and 3000 tons of PPS filament.

The PPS products of PPS resin and PPS modified material produced by Sichuan special new material Co., Ltd. have filled the gap of PPS industrial production in China.

Indicating the future direction of the industry

The key common technology of an industry often indicates the development direction of the industry.

For example, super cotton imitation technology is a key technology that has been highly praised by domestic and foreign textile science and technology and invested in R & D in recent years.

This technology can make chemical fiber very close to natural cotton, and some technical indicators even exceed cotton.

Popularly speaking, "super Imitation cotton" products, whether they are visual, tactile or functional (skin friendly, comfortable, washable), all have the excellent characteristics of cotton and chemical fiber, such as polyester, and achieve the effect of cotton and cotton.

"Super Imitation cotton" products should ensure that cotton has excellent softness and warmth retention, and also has good mechanical and chemical properties, even antistatic, anti pilling, antibacterial, flame retardant, far infrared, UV resistant and other functions.

With the improvement of the technology of "super cotton imitation", the added value of products will also increase.

Wang Huaping, vice president of the Research Institute of Donghua University and director of the Key Laboratory of high performance fiber and products education ministry, said that "super Imitation cotton" has opened up a new space for the development of chemical fiber industry.

He said that there is still a big gap between China's Imitation cotton products and foreign countries, especially in comparison with Japan. The key technology system, product system and standard system of "super Imitation cotton" products such as polymerization, spinning, weaving, dyeing and finishing have not yet formed and need to be strengthened.

He suggested that the industry should strengthen the research on the mechanism of dynamic thermal and moisture comfort of cotton fibers and products, and make clear the positioning and objectives of the products. The research on capillary wicking effect and dynamics, moisture absorption and wetting ability and dynamics of fiber and fabric such as imitation cotton fine denier or super fine denier, hydrophilic copolymerization modification, inorganic blending modification, surface roughening, section profiled, and so on will lay a scientific foundation for formulating cotton imitation function testing methods and indicators and standardizing market behavior.

It is understood that in order to ease the contradiction between supply and demand of cotton, effectively use excess polyester production capacity, relying on chemical fiber industry technology innovation strategic alliance, by the end of 2010, the Ministry of science and technology first launched the "12th Five-Year" National Science and technology support project "super cotton synthetic fiber and textile industrialization technology development".

The project has participated in the development of more than 20 units including the Chinese Academy of textile science, Donghua University, Yizheng chemical fiber Limited by Share Ltd and Taicang Jinhui chemical fiber Industrial Co., Ltd.

With the continuous improvement of key common technologies in textile industry, many key technology research and development and industrialization have become opportunities for the textile industry to nurture and develop strategic emerging industries.

Of course, because the research of key generic technology is difficult and the cycle is long, the development of industrial common key technologies can not be accomplished overnight.

But as the forward-looking and directional technology in the textile industry, especially the key common technologies such as basic materials, key processes, core components and system integration, we must firmly grasp and relax.

Because it represents the future of textile.
