Li Lingshen also highly affirmed the "national key R & D project in the field of fiber materials", which is the key national R & D program in 13th Five-Year.

He pointed out that at present, China's chemical fiber industry is facing the lack of independent innovation capability. The core technology and key equipment and application development of new and high technology fiber are urgently needed to break through. The key raw materials and core strains of bio based chemical fiber are also subject to practical problems such as foreign countries, equipment and raw materials are not matched and international dependence is high, fiber material independent brand and marketing network construction need to be strengthened.

In recent years, the national key R & D plan has focused on the major strategic tasks of the country, focusing on solving the bottlenecks and outstanding problems faced by the current national development, and implementing key technologies and products of major common features, and implementing cross sectoral, cross industry, cross regional R & D layout and collaborative innovation, providing continuous support and guidance for the main areas of national economic and social development.

The "national key R & D project in the field of fiber materials", a special national R & D program in 13th Five-Year, is an important measure to promote the development of high performance composite materials, advanced structural materials, new functional materials and green fiber materials. Through the breakthroughs in key technologies such as design and development of basic materials, manufacturing process and process optimization, and breakthroughs in localization equipment, high performance, high added value and green, efficient and low carbon production of fiber materials are realized.

He also shared the research results of various subjects in the project.

The exchange is the industrialization technology of flexible manufacturing and recycling of chemical fiber. He focuses on efficient flexible manufacturing technology and recycling technology.

Among them, the goal of high efficiency flexible manufacturing technology project is to realize the flexible and efficient manufacturing technology of polyester and polyamide fiber, which has reached the international advanced level. It is manifested in the following aspects: basic research, polyester, polyamide copolymerization, spinning forming and structural evolution mechanism, and full flow engineering simulation. In terms of key technologies, 3-5 key technologies of polyester and polyamide flexible and efficient manufacturing system, which are original, system integrated innovation and independent intellectual property rights, have been formed. In terms of application and demonstration, 5-8 demonstration projects and industrialization demonstration bases with 5-8 driving effects have been built to promote flexible and efficient preparation of polyester fiber production capacity of 4 million tons, and polyamide 6 fiber production capacity of 500 thousand tons.

Communication is the key technology of high quality essential flame retardant fiber and products.

She pointed out that fiber and products are important basic materials for national economy and people's livelihood. Polyester, polyamide and regenerated cellulose fibers, which account for more than 90% of the total chemical fiber, are all combustible fuels.

According to incomplete statistics, over 50% of fires in various types of fires are related to the ignition or combustion of textiles.

Based on this, many domestic and foreign institutions have carried out research on flame retardant technology, and made some progress. But there are some problems such as low flame retardancy, poor durability, large volume of smoke, serious droplet and high cost. Therefore, it is urgent to carry out research on high quality flame retardant fiber and products.

Wang Rui pointed out that the key technologies for high quality flame retardant fibers and products are to solve the problems of high efficiency flame retardant structure design and controllable equipment, high dispersion and suppression of flame retardants, synergism of flame retardant and smoke suppression, flame retardant and processability of fiber, serious contradiction between fiber melt forming and combustion droplet.

Results: the resistance to droplet research of flame retardant polyester fibers has made great progress. The maximum oxygen index reaches 40%, the UL94 test reaches V0 level and the smoke suppression performance is improved. The key equipment of the continuous flame polymerization polyester melt direct spinning has completed the relevant design and pformation work. The flame retardant polyamide 6 has entered the pilot stage, and the flame retardant PA6 slice has been prepared. The flame retardant PA66 vertical combustion test has reached UL 94 V-0 level, the limiting oxygen index is 33.2%, and has good flame retardant effect. The flame retardant cellulose fiber has completed the design and preparation of the flame retardant structure, and has made the flame retardant regenerated cellulose fiber whose fracture strength is greater than 2cN/dtex and the limiting oxygen index is 35%. In this project, the mechanism of flame retardancy and resistance to droplet and smoke suppression of fibers has been studied.

New 20 thousand flame retardant yarn production line.

In the report entitled "Research on organic inorganic hybrid materials and their applications", it is pointed out that great health is a global concept that goes through the necessities of life. Fiber materials are not only the raw materials of garments, home textiles, and industrial textiles, but also important basic materials and engineering materials. They are closely related and have great significance for national economic development and social progress.

15 years ago, Zhu Meifang put forward the idea of hybridization.

She said that if the idea was added to the research and development of fibers, various innovations could make fibers develop from traditional cloak and shelter to various functions at present.

In sharing, she briefly introduced the innovative results of several fibers used in PET, PA6, polypropylene PP, PLA, PHBV and so on.

Zhu Meifang suggested that in addition to textile and clothing, hybrid technology can also contribute to the prevention and treatment of dental diseases such as caries and periodontal diseases.

At present, hybrid resin materials are applied in the prevention and treatment of oral diseases. Among them, recycled materials are the core material of dental prosthesis (accounting for 70%).

Speaking of the market situation of hybrid resin materials, she said that at present, the technology and market of the material are monopolized by Europe and the United States, and the competitiveness of China's domestic products is relatively low.

China lacks high quality dental restorative materials, such as filling resins 40 years later than abroad. Clinical needs depend mainly on imports from abroad, and imports amount to billions of dollars annually.

Sharing is the project of preparation and application of reinforced materials for geotechnical engineering.

The research contents of the project are as follows: study stable and reliable polymerization system; study the preparation and industrialization technology of high strength and high modulus PVA, PAN fiber and high strength anti-aging PP fiber; study the preparation mechanism and industrialization technology of dispersant; study the service behavior and failure mechanism of building reinforced short fiber and geotextile; study the dispersion and application technology of short cut fiber in concrete and asphalt; demonstration project.

At the meeting, Zou Liming introduced these research contents one by one.

She said that the landmark achievements of the project include three main points: one is the key preparation technology and industrialization of large size, high strength and high modulus PVA fiber; two, the key preparation technology and industrialization of high-strength coarse PP filament needle punched geotextiles; and three, the early warning mechanism for plastic shrinkage cracking of cement-based materials.

In the report on the miracle of natural surpassing natural polyamide, the development and industrialization of Kaiser Based Polyamide were introduced.

Kaisai Biological Industry Co., Ltd. is the first and the only industry in the world to implement large-scale revolutionary industrial technologies such as long-chain dicarboxylic acid, bio butanol and bio based amine two by using biotechnology.

In recent years, Kaisai has developed bio based polyamine two and has excellent performance in biological based polyamide. In 2014, it completed the trial run of industrialization.

In 2016, Kaisai biological Xinjiang Wusu production base started construction. It is expected to achieve an annual capacity of 50 thousand tons of bio based amyl two amine, an annual capacity of 100 thousand tons of bio Based Polyamide and an annual capacity of 30 thousand tons of long-chain dicarboxylic acid.

Xu Xiaochen focuses on the new bio based polyamide fiber TLC, which is mainly derived from corn and other biomass materials. It has the characteristics of easy workability, dyeability and intrinsic flame retardancy, and has superior textile properties.

The high quality raw coloring fiber and its application are shared.

It is understood that the project has broken through the preparation technology of dyed polyester staple fiber of direct spinning superfine liquid, and has built a 30 thousand ton / year industrialization demonstration line. It has broken through the preparation technology of polyester staple fiber dyed by high strength raw liquid of melt direct spinning special black sewing thread, and built a 50 thousand ton / year industrialization demonstration line.

Jin Jian introduced that one of the key technologies of the project is raw material preparation technology -- special Pigments / dyestuff modification, ultrafine, stable dispersion and masterbatch preparation technology. The key research contents are migration resistant colorants research and pigment modification research.

He pointed out that the new synthetic colorants have good heat resistance and migration resistance through the structure design of colorants, especially in the PA applications, which achieve good boiling resistance, and achieve the organic combination of heat resistance, migration resistance and easy dispersity of dyes.

By modifying the pigment, the dispersity and dispersion stability of the pigment are improved, the filtration property of the masterbatch is improved, the coloring strength is improved, and the thermal stability is improved.
