In his remarks, duan xiaoping pointed out that polypropylene is an industry with excellent product performance and green production process. According to the statistics of the national bureau of statistics, from 2012 to 2017, the actual output of nearly 50 enterprises above the scale of polypropylene fiber in China was stable at about 300,000 tons, less than 1% of the total output of synthetic fiber, a variety with a small proportion of synthetic fiber. According to the actual survey and statistics of chemical fiber association, the production capacity of polypropylene fiber in China is 1.036 million tons, and the actual output is about 800,000 tons, among which the capacity of filament (including single silk) is 521,500 tons, the capacity of staple fiber is 240 thousand tons, the capacity of BCF is 119,500 tons, and the capacity of high-strength industrial silk is 1545 thousand tons. Due to the excellent properties of polypropylene fiber, its application in certain fields such as rope, ribbon, nonwovens, geotextiles, eisai, and high-end sportswear, it has maintained a steady development trend in recent years. Due to the historical development track, the industrial development level of polypropylene fiber in Europe and the United States is higher than that in China, especially in the field of industrial use and high-end sportswear. The use of polypropylene in these two fields is different from other chemical fiber varieties, which also makes the polypropylene industry more room for technological progress.

In his speech, guo briefly reviewed the development history of the polypropylene industry. In 1954, he said, ziegler and natta published patents for the manufacture of isotonic polypropylene; In 1957, Italian company first realized the industrial production of isotactic polypropylene; Since the 1960s, Japan has continuously increased investment in the research and development of high-performance, functional polypropylene, vigorously developed the use of polypropylene in decoration and industry, and expanded the application field of polypropylene. In the 1970s, the United States, Italy, the Czech republic and other countries began the development of polypropylene fine wire; In the mid-1980s, concrete strong polypropylene made progress. The United States and Western Europe began to use it in the construction industry. Since the 1990s, with the improvement of the performance of polypropylene fiber, the variety of polypropylene fiber is more diversified. The United States has developed polypropylene fiber with flame retardant, anti-static electricity and other functions, while the western European countries have successfully developed the new differentiated polypropylene fiber such as conductive polypropylene fiber, electric polypropylene fiber, and bioabsorption and degradation polypropylene fiber. By the end of the 20th century, differential polypropylene fiber, such as fine denier, flame retardant, antibacterial, anti-ultraviolet, anti-aging, and far infrared, was developed successively in China, with a certain yield. In the early 21st century, China's industry has further developed high strength, uv resistance, dyeing, fine Dan, super fine Dan and other polypropylene products. So far, most of the differential polypropylene have been produced and developed in China.
At present, compared with large chemical fiber, domestic pp manufacturing is still dominated by small and medium-sized enterprises, and the degree of industrial concentration needs to be further improved. To this end, Mr Guo said: "" we hope to constantly promote and deepen industrial technology exchanges and industry-university-research cooperation with the help of industrial associations as a bridge to promote industrial agglomeration and enhance the comprehensive competitiveness of the industry. Although polypropylene is a small variety of chemical fiber industry, but can have a large role. Polypropylene fiber is also the environmentally friendly industry with the lowest energy consumption and the lowest pollution in all chemical fiber industries. It is a sustainable industry. I believe that with the joint efforts of my colleagues in the industry, and through the continuous development and application of the functions and characteristics of polypropylene, especially the application of the unique characteristics of "acid and alkali resistance", the market prospect of polypropylene industry in the future will be greatly promising.

Li changqi, chairman of jiaxing shengbang machinery and equipment co., LTD., narrates "a method to rapidly upgrade polypropylene spinning equipment to the international level". He analyzed the current situation of domestic polypropylene spinning equipment (filament) : first, a large number of domestic equipment is used, and the equipment is produced by non-mainstream first-line chemical fiber equipment manufacturers. Second, the equipment is old and the technology is low. The hot roller USES steam jacket and multi - stage temperature control technology very few, winding head is basically a rabbit head form. Third, mainstream polypropylene equipment manufacturers basically do not have the high-end hot roll and winding first - class key components manufacturing capacity. Fourth, domestic polypropylene filament equipment technology development is a low gradually to high development process. Fifth, pp filament manufacturing enterprises are eager to get cost-effective equipment.
Li changqi said that around 1995, German and Japanese production of winding head to six (900.920 chuck) eight (1200 chuck) led, hot roller? 220 * 280,? 220 * 350,? 190*350mm long is dominant. The equipment is of higher quality than the equipment currently produced. However, due to its low production capacity and inadaptability to the high production requirements of domestic pet and polyamide fiber market, many of them are discontinued and in the state of being sold. If a large number of idle winding heads and hot rolls produced by Germany and Japan around 1995 are used for dressing and transformation in the polypropylene market, the equipment level of China's polypropylene market will be greatly improved.
In sharing "inventory management and optimization of polypropylene enterprises", huang yangming, technical director of China polypropylene network, pointed out that the inventory data of polypropylene enterprises cannot be updated in real time, manpower cost increases, and customer service quality needs to be improved. Under this background, if we want to do well inventory management, we need to carry out effective operation from three aspects: warehousing, material requisition and warehouse management. In this process, the management of input, sales, storage, and code scanning software is particularly important. Its advantages are: the number of electronic scale generation is directly input into the computer, and the accuracy is high; One-time investment, less labor, low cost, quick results, fast delivery; It can carry rich contents, trace quality problems and improve product competitiveness. Each code carries corporate information, increasing marketing opportunities and influence.
