How To Develop Large Variety Synthetic Fibers In The Era Of Meager Profit

The collaborative innovation system of the coloring fiber industry chain, which is closely led by the China Academy of textile science and technology, will take the polyester fiber, polyamide fiber and regenerated cellulose fiber as the key points, and break through the key core technologies in all links of the whole industry chain, so as to help the industry achieve rapid and benign development.

Duan Xiaoping, vice president of China Textile Industry Federation and President of China Chemical Fiber Industry Association, said in an interview: "the chemical fiber industry seems to have entered the state of" no man's land "and lost the target of learning. Under such circumstances, the world needs to develop together.

As a big country of chemical fiber, China has the responsibility and obligation to carry out the banner of R & D and invest in R & D to promote the development of global fiber industry.

China is the largest chemical fiber country in the world. It occupies 70% of the world's chemical fiber output. It is the only country that owns all kinds of chemical fiber, and the overall level of China's chemical fiber has been greatly improved. Especially in the conventional field, as well as high-performance fiber and differential fiber, China has been in the leading position.

The focus of the development of China's chemical fiber represents the future direction of the global fiber industry.

In 2015, the output of China's chemical fiber reached 48 million 310 thousand tons, and the proportion of chemical fiber to textile fiber processing increased from 70% in 2010 to 84.1%, which played an important supporting role in promoting the sustainable development of China's economy.

However, China's chemical fiber under the new normal is facing a stage of overcapacity.

According to statistics, China's fiber production capacity slowed down to 4.5% in 2015, and the global fiber processing volume is expected to grow at an average annual rate of 2.8% to 3%.

In particular, the large variety of synthetic fiber has entered the era of "meager profit". The development of PET and PA fibers mainly depends on tracking and imitation, which restricts the sustainable development of textile and related industries.

However, from the perspective of demand, the future

The increment still depends on the large variety of general synthetic fiber.

According to the relevant data, the United Nations is expected to have a global population of 7 billion 760 million in 2020, a net increase of 410 million, an average annual growth rate of 1.09%, and a net increase of 740 million people in the 2020~2030 years, with an average annual growth rate of 0.9%.

With the growth of population, fiber consumption will continue to grow correspondingly.

"At the end of 13th Five-Year, the world's per capita fiber consumption will exceed 12.5 kg / person, an increase of 0.6 kg / person over 2015, and the total global fiber consumption will be close to 100 million tons.

Among them, synthetic fiber will be the embodiment of textile fiber.

The main force. "

Luo Hongjing, deputy director of optimization and consultation center of China Petrochemical Corp economic and Technological Research Institute, analyzed.

Zhu Meifang, Dean of the school of materials science and engineering, Donghua University, also believes that in the future, the proportion of polyester production capacity and demand will account for about 88% of the total domestic fiber, and the production capacity and demand of nylon will increase by 9% and 12%, and the proportion of total fiber will increase to 6%.

How to develop large variety of synthetic fibers in the era of meager profits under strong demand? "The industry needs to rely on large capacity engineering foundation to promote the quality of conventional products, enhance the added value of products, and achieve the high quality and multiple functions of general fiber."

Zhu Meifang pointed out that in the future, fiber components should be developed from single to complex, simple and multiple structures. The research of fiber function should be from passive adaptation to active innovation design, and at the same time, basic research should be strengthened, so as to infuse the driving force for product research and development, support the development of original key technologies, and increase the crossover and integration of most disciplines and technologies.

Fortunately, the industry has already started related research.

Enterprise level is also constantly innovating research and development, and has achieved good results.

Chen Fei, vice president of Fujian Jinjiang science and Technology Co., Ltd.

Relying on the unique core technology of the company, science and technology has developed three high quality nylon products, including porous fine denier fiber, raw liquid coloring fiber and functional series fiber, and the market feedback effect is very good.

"With the continuous development of society, people's material life needs are constantly improving.

In the future, the development of nylon fiber is bound to move towards a functional and high-end direction.

Chen Fei said that in the future, Jinjiang science and technology will develop fast thermal nylon fiber, high stretch nylon fiber, conductive nylon fiber and other high-end products.

He Zhuosheng, President of the China polyamide fiber branch of China Chemical Fiber Industry Association and deputy general manager of Guangdong Xinhui Mei Da nylon Limited by Share Ltd, also proposed that the production technology of caprolactam, the main raw material of nylon, has made breakthroughs. The large capacity nylon 6 polymerization device and technology have been further improved, and the spinning domestic equipment is also integrated with imported equipment. In the future, the product structure of nylon should be further optimized.

He analyzed that compared with the developed countries, the proportion of China's industrial plastics and industrial yarn was low, and the variety structure still had much room for optimization. Moreover, under the influence of the increase of national income and the change of consumption concept, the development potential of fibers and decorative fibers used in the automobile industry had great potential.
