< p > it is easy to see that China's chemical fiber imports are decreasing and exports are increasing.

China's chemical fiber industry has developed from nothing to a few generations after several generations of "a target=" _blank "href=" http://www.91se91.com/ "> textile" /a ". At present, China's chemical fiber production accounts for 65% of the world's output. Chemical fiber products cover almost all varieties. The main chemical fiber technology and equipment have reached the international advanced level and become the world's largest chemical fiber producer with the largest scale, the most complete industrial chain and strong competitiveness.

< p > < strong > reconstructing the new competitive advantage of chemical fiber industry < /strong > < /p >

P entered into the twenty-first Century, and new technologies such as polymer materials, bioengineering and microelectronics developed rapidly, which greatly promoted the technological progress of traditional industries such as chemical fiber and textile.

The world's chemical fiber industry has entered a new stage of competition, which is based on high-tech, high-tech products and based on Information Engineering and knowledge economy.

With the continuous rise of various costs, China's economy has entered the era of high cost, and the chemical fiber industry is no exception.

The low cost competitive advantage of the earlier years has ceased to exist. Once the low cost development mode is the supporting point for the rapid development of China's chemical fiber industry, it has become a resistance to sustainable development of the industry.

At present, chemical fiber industry needs to solve the problem of how to break through the high cost limitation besides green environmental protection and resource saving.

< /p >

At the same time, there are still several problems to be solved in China's chemical fiber industry at present. First, the proportion of high-tech fiber and high value-added products is relatively low, and the core technology and key technology and equipment of the vast majority of high-tech fibers need to be further improved. "P"

If the ability of independent innovation does not improve, it will affect the innovation and upgrading of the entire chemical fiber industry.

Two, the domestic chemical fiber industry has experienced a period of rapid development, but mainly based on the expansion of conventional fiber production capacity. The problem of excessive development of conventional and homogeneous products is highlighted.

In the period of economic development and large fluctuations in market demand, many enterprises still remain at the low level of low price competition.

Three, China's chemical fiber enterprises are still mainly production oriented, industrial marketing and brand building lag behind, high cost and low price competition eroded profit margins, resulting in a low overall profit level.

< /p >

< p > therefore, in the critical period of China's chemical fiber entering the upgrading and improving efficiency, we should accelerate the pformation of the development mode and development path, cultivate and form a new competitive advantage with innovation, quality, brand and service as the core, and achieve the upgrading of the industrial chain and value chain from the low end to the high end, and enhance the core competitiveness of enterprises and the added value of products. This is the only way to reconstruct the new competitive advantage of China's chemical fiber industry, realize the sustainable development of China's chemical fiber industry, and become the world's strong chemical fiber industry power.

< /p >

< p > < strong > basically is to inject new vitality < /strong > < /p >.

< p > a large number of practices show that to adapt to the above development conditions, the fundamental path is to inject new vitality and change the development mode, so as to create an upgraded version of China's chemical fiber industry chain.

< /p >

< p > the driving force of technological innovation industry upgrading.

At present, the main varieties of conventional fibers in China have played a decisive role in the world. At the same time, they also support the rapid development of China's chemical fiber industry. However, the structural overcapacity of conventional low level fiber varieties is also prominent.

With the rapid development of modern technology and related industries in China, the demand for high quality and high functionality of materials related to chemical fiber industry will promote the development of high-tech fibers, high-performance differential functional fibers and their composites.

In the face of such a situation, we must pay close attention to the latest trend of global technology development, accelerate the pace of technological innovation in the chemical fiber industry through various ways such as "original innovation", "integrated innovation", "digestion and absorption and re innovation", and promote the application of high and new technology in the chemical fiber industry, and speed up the adjustment and optimization of the industrial structure.

Modern technology of materials science, information technology, nanotechnology, biochemical technology and other basic theories are applied to pform and enhance the technology, equipment and process control in the chemical fiber industry, and solve many problems in the whole process of chemical fiber production, and gradually enhance the capability of independent research and development.

< /p >

< p > the only way to upgrade resources recycling industry.

Under today's complex global economic environment, resource constraints and environmental pressures pose a greater challenge to the upgrading of chemical fiber industry chain.

In the face of this global problem, in addition to shifting conventional production capacity and developing high-tech fiber and other development strategies to resolve the pressure from resources and environment, we should actively promote the development of circular economy, rapidly expand the scale of circular economy industry, improve the level of technology and product quality, accelerate the development of diversification, differentiation and high technology content, and seek the healthy and sustainable development of the chemical fiber industry.

By the end of 2012, China's regenerated polyester fiber had an annual capacity of about 8000000 tons, and its actual output reached 4 million 500 thousand tons, accounting for 80% of the world's total output.

China has become the first producer of regenerated polyester fiber.

In addition, the recovery and utilization of other fibers such as nylon and polypropylene have also made great progress. The number of recycled materials has been increasing year by year, and the level of technology has been increasing. The application of recycled fiber has covered most of the downstream areas. In terms of raw materials and accessories recycling, such as large-scale polyester plant, acetaldehyde recovery and large nylon polymerization plant, the technology has been developed successfully, and the recovery rate can reach 99.5% and 100% respectively. The technology has been applied in major enterprises and major projects in the industry. The coloring and spinning technology of chemical fiber has been widely applied. The annual output capacity of 1 million 500 thousand tons has been formed. Compared with traditional dyeing technology, the technology can reduce more than 70% of CO2 exhaust gas, and tons of fiber can save 140 tons of dyeing water consumption.

< p > green channel of low carbon economic fiber upgrading.

With the continuous expansion of the scale of the chemical fiber industry, aiming at reducing greenhouse gas emissions, building a production system based on low energy consumption and low pollution, including low carbon energy system, low carbon technology and low carbon industrial system, is an important task of the low carbon economy of chemical fiber industry.

< /p >

For this purpose, we vigorously promote new technologies, technologies, equipment and materials for energy conservation, emission reduction, water saving, consumption reduction, green and low-carbon, promote cleaner production, implement circular economy, and develop degradable, renewable, recyclable materials, such as bio based fiber materials, for traditional fields and new fields. P

In particular, we should focus on the development and application of 4H4L products and practical technologies with high efficiency, high added value, high performance, high yield, low consumption, low cost, low price and low risk (environment) to meet the green demand of low carbon economy, environmental friendliness and ecological cycle, and meet the new demand in the new field (non consumer goods and non-traditional areas) and the new round of growth in industry demand.
