As a rising star of synthetic fiber, polypropylene has a relatively small scale, but it has abundant raw materials, simple production process, low energy consumption and low pollution in the production process, and has the advantage of sustainable development. Polypropylene products are characterized by light weight, high strength, acid and alkali resistance, especially in recent years, the development of functional polypropylene, products are widely used in carpets, various ropes, fishing nets, building reinforcement materials, packaging materials and other industrial, household goods and medical Health and other fields. Although China's polypropylene R&D has started late, after nearly 20 years of catching up, China's polypropylene products cover high-strength, anti-UV, dyeable, fine-denier, ultra-fine denier and other differentiated polypropylene products, and have become the world's largest polypropylene producer.

At present, socialism with Chinese characteristics has entered a new era. China's economy has shifted from a high-speed growth stage to a high-quality development stage, and the textile and chemical fiber industry has also moved into a new era of high-quality development. How to grasp the opportunities of high-quality development in the polypropylene industry, how to deal with the impact of international market competition and trade friction on the development of the industry, how to improve the competitiveness of polypropylene in the international market, how to break through the bottleneck of the development of polypropylene enterprises, how to give full play to the local textile chemical fiber industry The advantages of chain linkage development, mastering the development trend of chemical fiber industry and polypropylene industry chain, focusing on polypropylene raw materials, products and application development, promoting the transformation and upgrading of polypropylene industry to achieve high quality development are the concerns of the whole industry and the hotspot of the conference.

Du Xiaoping, vice president of the China National Textile and Apparel Council and president of the China Chemical Fiber Industry Association, pointed out in his speech that after 40 years of reform and opening up, the chemical fiber industry has created unprecedented profound changes and achieved remarkable results. China has become a global The most complete and largest chemical fiber production, consumption and exporting country in the industry chain. Polypropylene is a small variety in the chemical fiber industry, but it is also an industry with excellent performance and green production process. According to the statistics of the National Bureau of Statistics, in 2012-2017, the actual output of nearly 50 enterprises above the scale of China's polypropylene is stable at around 300,000 tons, less than 1% of the total output of synthetic fibers, which is a small proportion of synthetic fibers. It is mainly distributed in Jiangsu, Zhejiang, Shandong and Guangdong in the southeast coast. Due to the excellent performance of polypropylene, its application in specific fields such as ropes, ribbons, nonwovens, geotextiles, adobes, and high-end sportswear has maintained a steady development in recent years. Compared with the application of foreign polypropylene in industrial and high-end sportswear, this is also the growth point of our future industry. The development of new technologies, new equipment, intelligent manufacturing, Internet +, functional and high value-added products is the responsibility of our new generation of polypropylene people.

Liu Duanxiong, deputy mayor of the People's Government of Jieyang City, Guangdong Province, introduced the industrial development trend of Jieyang City in Guangdong Province in his speech. He pointed out that Jieyang is a manufacturing city in Guangdong and a private economy. It has traditional industries such as metal, petrochemical, textile and garment, food and medicine. Among them, Sinopec and textiles and garments are pillar industries of Jieyang, with a sound industrial chain, including textiles. The output value of chemical fiber clothing reached more than 130 billion yuan. At present, the total investment of 65.43 billion yuan, annual production of 20 million tons of refining + 1.2 million tons of ethylene + 2.6 million tons of aromatics refining and chemical integration, as well as textile printing and dyeing environmental protection integrated processing center and other major projects to accelerate, will certainly drive the realization of petrochemicals and The extension and reconstruction of the chain of the textile and garment industry has also brought important opportunities for the development of the chemical fiber industry and created favorable conditions. In the future, Jieyang will insist on serving enterprises and projects as the top priority, further improve the support measures for private enterprises and small and medium-sized enterprises, comprehensively optimize the business environment, and help enterprises solve practical problems. I hope that this meeting will be an opportunity to focus on major projects, plan cooperation and cut through, create mutual benefits and win-win, and work together to promote the high-quality development of the chemical fiber industry.

Ten experts and guests at the scene discussed the domestic and international economic environment, textile industry, and polypropylene industry. Li Zengjun, Secretary General of the Polypropylene Branch of China Chemical Fiber Industry Association, presided over this session.

In China's "Guidelines for the Development of the "13th Five-Year Plan for Chemical Fiber Industry", we will position the development status of China's "fiber materials" industry from three aspects: First, it is an important pillar industry for the overall competitiveness of the textile industry. The second is an industry with international competitive advantages. Third, it is an important part of strategic emerging industries. Chemical fiber is no longer only used in traditional textile and clothing. It is actually related to defense, military, transportation, energy, medical and health. In the future, we will focus on fiber new materials, green manufacturing, intelligent manufacturing, and brand cultivation. Finally, it introduces the representative research and development achievements of Donghua University: scientific problems and key technologies of carbon fiber preparation process and its system engineering research; molecular chain conformation control and molding technology research of organic high-performance fiber preparation; molecular design of general fiber Aggregation structure and simulation super-realization research; organic/inorganic nano-hybrid materials and nano-fiber forming basic research; renewable resource fiber material preparation and biomimetic technology research.

Gao Chunyu, a senior researcher at the Beijing Research Center of Dalian Commodity Exchange, analyzed the current status and development trends of the global olefins market, the global polypropylene market and China's polypropylene market, and listed the main factors affecting the price of polyolefins in 2019. In 2018, the global new ethylene production capacity was 9.12 million tons/year, and the new propylene production capacity was 6.35 million tons/year. In 2019, ethylene production capacity will increase by 5.68 million tons, of which new capacity will increase by 3.3 million tons per year in North America and 1.98 million tons per year in Asia. As capacity growth is faster than demand growth, ethylene production rate may rebound from 2018; In 2019, 3.2 million tons of propylene per year will be added, of which nearly 3 million tons will be added in the Asia-Pacific region. The growth rate will slow down and the propylene operating rate will rebound to 79%.

In 2017, the global polypropylene production capacity increased by nearly 3.7 million tons per year, and the demand growth rate has declined. In 2017, the global demand for polypropylene was 70.70 million tons, an increase of 4.0% year-on-year. The demand growth rate has dropped from 2016, and the operating rate of polypropylene equipment has also declined. It is estimated that by 2020, the world's polypropylene production capacity will reach 84.71 million tons / year, and the demand will reach 76.88 million tons. At present, injection molding, film and wire drawing are still the main applications of polypropylene. In recent years, the demand for polypropylene for drawing and film has been steadily increasing. Other fast-growing applications include pipes, pipe fittings and coating materials. In China's polypropylene consumption, weaving, injection molding and film are the main consumption areas. It is estimated that domestic polypropylene production capacity will be 29 million tons/year in 2019, and demand will reach 29 million tons, up 7.0% year-on-year. It is estimated that the annual output will be about 24 million tons and the net import volume will be about 5 million tons.

Gu Qingliang, a professor at the School of Management at Donghua University, interprets the current textile trade change from the historical perspective of the development of the times. The report introduces the era of global industrial civilization, has passed the first industrial revolution of I-III, is currently undergoing the fourth industrial revolution (4IR), through subversive information and communication technology, quantum technology, artificial intelligence technology, 3D technology, digital Data technology and other deep technology, and its digital laser, material technology, biotechnology, nanotechnology, green technology, robots and other special technologies, open up new application markets, such as carbon fiber structural materials, mobile payment, face recognition, new energy vehicles, Speech recognition, driverless and other applications. China's technological innovation and application leading role in the 4IR industry has emerged. New types of transportation electric vehicles such as internal combustion vehicles, new energy vehicles, unmanned vehicles, high-speed rail and magnetic levitation (opening 600 kilometers in 2020) may become one of the driving forces of the new cycle. Applied to chemical fiber enterprises, the Agreement on Textiles and Clothing (ATC) stipulates that textile quotas will be abolished on January 1, 2005, marking the return of the global textile and apparel trade to the multilateral trading system and entering the post-MFA (multi-fiber agreement) era. The world pattern of major textile and apparel exporting countries has had a huge impact, and China’s textile and apparel exports are facing a new economic environment. China's textile and garment industry plays an important role. Textiles and clothing have been an important source of China's trade surplus for many years. Although China's textile and garment industry exports are affected by unfavorable factors such as the interference of US and European trade frictions, they still maintain a steady growth momentum. At present, the world is in a new era. The inevitable, uneven and inadequate conflicts are the main features. Globalization, trade liberalization is unstoppable, and the inclusive growth of the Belt and Road Initiative is the main task of China's textile industry. Fashion innovation and the creation of China's status are important measures for us to cope with the current world changes.

Situ Jianyu, deputy director of the Guangdong Chemical Fiber Research Institute, introduced the development of the chemical fiber industry in the Pearl River Delta region. In 1983, Guangdong Province's first full-scale introduction of polyester high-speed spinning production line was successfully put into operation at Xinhui Polyester Factory, which opened the development boom of Guangdong chemical fiber. By the end of 1996, Guangdong had accounted for a quarter of the national output. The full range of products, especially polyester filament yarn, is the first in the country, both in terms of advanced technology and production capacity. With the improvement of the localization of chemical fiber equipment, the advantages of low input and high output of domestically produced equipment are very obvious. The problem of high input and low output in the early stage of Guangdong chemical fiber industry is gradually revealed. The Guangdong chemical fiber industry has been brilliant for more than ten years. Enter the adjustment phase. As China's economic development gradually shifts from the Pearl River Delta region to the Yangtze River Delta region, Guangdong's industrial structure has also begun to change. The tertiary industry has become the largest industry in Guangdong. The chemical fiber industry faces problems such as lack of talent pool, low equipment production efficiency and high cost. Leading to the continued decline of the chemical fiber industry. In the transformation and development of the chemical fiber industry in the Pearl River Delta region, it is mainly reflected in the research and development of product differentiation, deep processing of products and non-woven fabrics. Clothing and apparel is an important direction of industrial transformation. In 2016, the total sales value of Guangdong apparel and apparel industry was 405.767 billion yuan, a year-on-year increase of 2.4%; the export of clothing was 32.732 billion US dollars, accounting for 25.79% of the country. The Guangdong garment industry has maintained a stable operation and continues to maintain its leading position throughout the country. Industrial textiles are an important extension of the chemical fiber industry, and industrial textiles based on non-woven fabrics have maintained a good growth momentum. As a unique branch of the textile industry, it is a short-flow, high-efficiency, low-emissions industry and one of the more active areas of technological innovation. In the province, the industrial agglomeration effect has been gradually improved, and various industrial clusters such as Nanhai medical and health materials, Guangzhou Conghua packaging household materials, Jiangmen geotechnical construction materials, and Dongguan home textile automotive interior materials have been formed.

Cai Zhengguo, a professor at the School of Materials Science and Engineering at Donghua University, said that polyolefin is a high-molecular material with a large output and a wide range of applications in the world. In 2014, the output reached 140 million tons. However, polyolefins are non-polar polymers, and this inherent defect severely hampers the use of polyolefins in many fields. The introduction of a polar group or a polar molecular segment into a polyolefin molecular chain to prepare a functionalized polyolefin can effectively improve the properties of the polyolefin material, for example, imparting hydrophilicity, colorability, and polarity to the polyolefin. Molecular compatibility, etc., thereby increasing its high added value. Cai Zhengguo introduced the development of polyolefin catalysts and hoped to achieve coordination copolymerization of olefins with polar monomers by designing transition metal catalysts. The realization of this process is very challenging and is considered to be one of the last “Holy Grail” in the polyolefin field. The report focuses on the copolymerization modification of functionalized polypropylene by introducing hydroxyl groups, which effectively improves the mechanical properties, oxidation resistance, thermal stability, light stability and dielectric properties of polypropylene. The application of functionalized polypropylene in polypropylene was shared.

Wang Min, senior engineer of Beijing Zhongli Machine Engineering Technology Co., Ltd., introduced the research basis, positioning, scope of use and the progress of the polypropylene special project. According to the compilation requirements, the special research work of polypropylene mainly investigated the situation of the production enterprises of the polypropylene project, the supervision of the local government management department on the project establishment, construction and operation of the polypropylene project, the foreign standards and norms of similar projects, and the mandatory in the original regulations.
